Cross-platform frameworks provide mobile app developers with a comprehensive set of tools designed to improve productivity by solving common problems. The question is which frameworks are best for you doing mobile development. To help you answer this question, we have prepared a special list of cross-platform frameworks for developing high-quality mobile applications.
Developing a mobile application using a cross-platform framework is a shorter path to successfully completing the task.
With nearly three million apps on Google Play, the Android operating system dominates the mobile landscape. Individuals, small companies and large enterprises are working hard to establish a strong mobile presence and capture market share. However, not everyone has the proper experience and resources needed to create a good mobile application from scratch using native tools.
The goal of frameworks is to make mobile app development as easy as possible.
List of cross-platform application development frameworks:
- Corona SDK;
Is it easy to create applications and games using Corona SDK? The creators of the Corona SDK framework promise ten times faster development of games and mobile applications. How is this even possible? This is likely due to the fact that the internal structure of the Corona application is entirely based on Lua, a lightweight multi-paradigmatic programming language with an emphasis on speed, portability, extensibility and ease of use.
The official Corona SDK website contains guides, lessons, and examples designed to turn novice mobile application developers into experienced professionals. Guides and tips cover all sorts of developer topics. From the basics of mobile development to more advanced topics. The Corona SDK framework is absolutely free. We remember about cross-platform. It runs on both Windows and Mac OS X and supports real-time application testing.
- TheAppBuilder;
So, description TheAppBuilder is a framework used by some of the largest organizations in the world, equipped with a user interface to speed up the development of application code. There are reviews that the version works best when used to create company presentations and other information applications. The framework comes with ready-made blocks for push notifications, feedback, surveys, content updates, analytics and much more. Best of all, TheAppBuilder integrates directly with Google Play, allowing you to publish ready-made apps with one click.
- Xamarin;
The Xamarin framework was developed by the same people who created Mono, compliant with the ECMA standard, and has a set of tools compatible with the .NET Framework. Xamarin offers developers a single C# codebase that they can use to create their own apps for all major mobile operating systems.
Unlike many other frameworks, Xamarin has already been used by more than 1.4 million developers around the world. With Xamarin for Visual Studio, developers can take advantage of the power of Microsoft Visual Studio and all its advanced features, including code completion, IntelliSense, and app debugging on a simulator or mobile device. The Xamarin Test Cloud feature allows you to instantly test applications on up to 2,000 real devices in the cloud (remotely, via the Internet). This is by far the best way to deal with the severe fragmentation of the Android ecosystem and release bug-free mobile apps that run without any major issues on most gadgets.
- Appcelerator Titanium;
The Appcelerator Titanium framework is part of the Appcelerator Platform, which includes all the tools mobile app developers need to build, test, and deploy highly optimized apps. The Titanium framework uses JavaScript to call a vast collection of APIs. These APIs call native operating system functions, providing exceptional performance and a natural appearance.
Titanium includes a visually oriented mobile app development process that relies heavily on pre-built code blocks that can be assembled via drag and drop. You can create data models programmatically or visually. Test your finished mobile apps in the cloud and track them with the Mobile Lifecycle dashboard, which provides valuable insight into app performance.
- PhoneGap;
PhoneGap from Adobe is one of the world's most popular frameworks for developing Android applications. It is created by the Apache Cordova development team. An open source mobile application development environment that uses CSS3 and HTML5, as well as JavaScript for cross-platform development. PhoneGap is also completely open source software.
It is based on an intuitive desktop application used to create applications and connect these applications to mobile devices (phones/smartphones, tablets). Finally, no more obscure text commands that are easy to get wrong and hard to remember. The fantastic desktop app is complemented by the PhoneGap mobile app. The application allows you to instantly see changes on your connected mobile device. Other things that make PhoneGap so recommended are its large library of plugins, third-party tools, and thriving community.
- Ionic;
Ionic is a free and open source framework licensed under the MIT license. It offers a whole library of components and tools. Ionic allows you to develop progressive web apps and native mobile apps for every major app store - all from a single codebase. Thanks to the best native plugins, it's extremely easy to use features like Bluetooth and Health Kit, and fingerprint authentication is also supported.
Ionic is also designed for performance tuning and optimization. All applications built using Ionic look like they are standardized and they work equally well. To date, nearly four million applications have been created by five million Ionic developers around the world. If you want to join them, visit the official website and learn more about this framework.
- NativeScript;
JavaScript and Angular, as well as TypeScript, are perhaps the most commonly used web development technologies. With the NativeScript framework, you can also use them to create applications. Simply put, NativeScript creates platform-specific user interfaces from a single code base. Unlike other integrated frameworks, NativeScript is supported by Telerik, a Bulgarian company that offers various software tools.
Do you need lessons on creating mobile applications in the cross-platform NativeScript framework? To help mobile application developers become familiar with this framework, the official website contains many examples and detailed teaching aids. You can view real implementations of mobile applications, study official documentation, and even dive into the source code.
- React Native;
React Native is developed by Facebook and used by Instagram, Tesla, Airbnb, Baidu, Walmart and many other Fortune 500 companies. Facebook's React JavaScript framework is open source ( open source). Since React Native uses the same UI building blocks as regular mobile apps for iOS and Android gadgets, it is impossible to differentiate a React Native app from an app built using Objective-C or Java. Once you update the source code, you will immediately see the changes in the application preview window. If you ever feel the need to manually optimize certain parts of your application, React Native allows you to combine native code with components written in Swift or Objective-C and Java.
- Sencha Touch.
Sencha Touch what is it? Like TheAppBuilder, it is an enterprise framework for creating universal mobile applications. It uses hardware acceleration techniques to achieve high performance. Sencha Touch comes with five dozen built-in UI components and decent looking themes, making it easy to create amazing apps that attract users.
The framework includes a robust data package that can use data from any internal source data. With this package, you can create collections of data using highly functional models that offer features such as sorting and filtering. Sencha Touch has received praise from many influential companies and organizations.
Conclusion of the review of cross-platform frameworks for mobile application development:
No matter which mobile app development framework you choose, don't be afraid to change your mind if you ever feel like there are better development environment options. Cross-platform frameworks are extremely fluid, with new ones being released on a regular basis. Their goal is to help you quickly turn a rough idea into a working app, and a working mobile app into a finished product. In the end, it doesn't matter whether you achieve your goal using the latest modern framework that everyone is talking about, or a long-established framework that is starting to gather dust.
When Chinese I.T. Huawei company decided to unveil its new multimedia phone surrounded by the ornate National Museum of Catalonia in Barcelona, it certainly gave hints to the journalists present (covering technology news) of what they would see. After all, the recently introduced foldable smartphone Huawei Mate X looks a bit like a rare Picasso painting.
First review of Huawei Mate X: a smartphone with a folding screen - attractive, powerful technical specifications and an incredibly expensive price to buy it.
So, what is the Huawei Mate X smartphone? The impression from the first review of Huawei Mate X can be expressed by the phrase that this smartphone is great. Even the phrase that this is a beautiful smartphone softens the review a little. Rather, he is magnificent in his own way. It has perhaps the most decent industrial design of any mobile phone that the tech giants have ever released in the last few years. New Huawei a smartphone from contemplation and deep imagination, clearly expands the boundaries of what smartphones can be. Since the size of a smartphone screen easily turns into a tablet one. Thus, mobile content can be viewed in a convenient way.
Those who know everything about phones might think that when asked for a unique price, the Mate X is a bit like the Picasso story in that it is a very expensive smartphone. The Mate X has raised the bar for smartphone prices. But perhaps, given the specifications on offer, it can justify its high price for those deciding which phone to buy.
Display on Huawei Mate X.
Which display is better? Huawei Mate X has a single display that can be transformed into three different configurations. The first mode is 8-inch tablet. It's an almost perfect square with an aspect ratio of 8:7.1 and a resolution of 2480 by 2200 pixels.
Since the screen is on outside smartphone, when the mobile device is folded, you get two screens. The front screen offers 6.6 inches from edge to edge, complemented by a 19.5:9 aspect ratio and a pixel resolution of 2480 by 1148.
There are also rear end, which offers fewer screen inches because it houses the device's cameras and handle. You will primarily use this part to take selfie photos. This part provides a decent (but thin) screen size of 6.38 inches with a somewhat compressed 25:9 aspect ratio and a resolution of 2480 by 892 pixels.
How comfortable is the Huawei Mate X in terms of thickness?
When mobile Huawei phone The Mate X is folded at 11 millimeters thick, and unlike its rival phone Samsung Galaxy Fold, there is no bulky gap. It is completely flat and locks into place with just one click. It would be interesting to test how well it locks when thrown into a purse, for example, and see if it can accidentally open or not.
When unfolded, the Mate X smartphone is 5.4 mm thick, which is slightly thinner than the iPad Pro!
On Huawei Mate X, the camera, the pen - everything is for the user!
A quick look at the side of the Huawei Mate X - it's a handle (Huawei's fairly descriptive term). The device contains three mobile cameras, including one using Leica hardware. In technology news, this was not a surprise. The same configuration has appeared on all Huawei phones, starting with the P20 Pro model. It would be strange if the manufacturer Huawei refused such a function in such a revolutionary device.
You may notice that the phone does not have a dedicated front-facing selfie camera. This is because the three rear cameras are selfie cameras. To take a photo of yourself, you just need to fold your phone and flip it over.
It's all pretty exciting. Huawei premium phones are regularly considered to be phones with the best cameras on the market. While the company didn't share any camera samples during the launch event, it's fair to say that some people love the experience of taking selfies with a high-end mobile camera enhanced by Master AI software.
And because the back of the Mate X also contains a screen, you can use your smartphone when taking photos, for example to show the subject of your photo a preview of how they'll end up looking in the photo.
Huawei employees claim that there are no problems with the camera on the Mate X model. This is good news, both in terms of appearance and overall durability. The latter is what the company is focusing on as it announced a specially designed protective case with the phone.
New 5G connectivity and performance for the Mate X smartphone.
When reviewing the Mate X, it's important to remember that Huawei is more than just a phone maker. It targets a variety of IT areas, including SoC design. Therefore, it is not surprising that the Mate X uses a Balong 5G modem, as well as a Huawei Kirin 980 processor.
The modem is especially interesting as Huawei promises that performance will be more than double that of modems from competing companies such as Qualcomm Snapdragon and Samsung Exynos. It is assumed that users who can afford to buy Huawei Mate X in stores will be able to use the download speed of 4.6 Gbps, for example, to download a 1 GB movie in just three seconds. Of course, right now, we have not been able to independently verify this, so for now we can only take our word for it.
What operating system is installed on Huawei Mate X?
From the point of view software, Mate X runs Google Android 9.0 Pie system.
A Huawei spokesperson also said that Desktop Mode software will be available for its latest foldable phone, allowing the Mate X to be used as a smartphone, tablet, or even a desktop computer.
Huawei Mate X memory.
Mate X is a mobile phone with two SIM cards, one slot of which supports 5G network, and the other is limited to 4G communication. If you don't need the latter feature, you can simply insert an NM card (clarification, NM is a nano memory card invented by Huawei that offers the same type of memory as a microSD memory card, but in a smaller form factor) and add additional a place to store data in a mobile device. At the same time, the basic version of the smartphone is available with 512 GB of memory. Even the most dedicated filmmakers are unlikely to use all that storage capacity in a mobile phone.
Battery for Mate X.
With such a big screen to work with, you'll be glad to know that the Huawei Mate X phone launched with a pretty gigantic battery. The device has two cells, which together measure up to a respectable 4500 mAh. Unfortunately, there are no battery tests right now, so it's difficult to say how this translates into actual use of the new smartphone.
The Chinese company shared that the Mate X comes with a 55W super charging feature that can recharge the phone's battery by 85 percent in just thirty minutes.
Huawei Mate X pricing.
The Huawei Mate X is perhaps the most important phone ever introduced by the rising Chinese tech brand, and not just because it cements its reputation as an innovative premium handset maker. This phone implements the company's more than three years of research and development and integrates advances in materials technology and communications equipment.
With this in mind, don't be surprised that the smartphone comes with really expensive prices, starting at 2,299 euros. When Huawei CEO Richard Yu (the English spelling of his name is "Richard Yu") broke the news, the silence from the crowd he had previously enjoyed was replaced by whispers of questioning. How much, how much does it cost?
Speaking of prices, it is about 300 euros more expensive than the flagship mobile Samsung device Galaxy Fold. And it's about 800 Euro more expensive than the most expensive Apple iPhone. Price-wise, the Mate X is in the same range as the company's previous luxury phones that bore the brand of luxury car brands, namely Porsche.
Huawei is not oblivious to the high cost of the Mate X, and during the conversation, Richard Yu said that the price of the phone reflects the high cost of research and development mobile device. He explained that the patented hinge that separates the two displays was a three-year development process and contains over a hundred different parts. This kind of research and development is not cheap, and it is inevitable that there will be costs.
However, two things are inevitable. Firstly, there will be no shortage of enthusiastic pioneers willing to save on a lot in order to save up the money for a premium phone. For these buyers, there is an undeniable allure to being among the first to own something special. Perhaps Huawei can take advantage of the news buzz and benefit from more than just selling cheaper phones.
Secondly, prices on the market will inevitably decline. Perhaps not for this smartphone, but certainly for foldable smartphones in general. By and large, the price of 2300 Euros per phone will be perceived as a deviation from the norm. This will be driven by several factors, ranging from inevitable cost savings to competition from other up-and-coming brands like Xiaomi and OPPO, which are making strong inroads into the Western smartphone market.
Availability of purchasing Huawei Mate X.
For example, Huawei hasn't said how much the device will cost in the UK, but if you're guessing, it'll probably cost around £2,300. This assumption takes into account previous price trends, high UK sales tax and the continued decline of the pound.
Also, Huawei CEO Yu did not mention any plans to release the Mate X in the United States. Which is not surprising. The company rarely releases phones in the US. Thus, the Mate 20 Pro smartphone, which until recently was the best Android phone and which could be bought for reasonable money, was completely absent from the American market, which forced American consumers to order the smartphone from abroad. This situation could push prices even higher for US users, who may be forced to pay high customs duties and taxes.
When will it be possible to buy Huawei Mate X?
Huawei has announced that the Mate X will be released mid-year. Unfortunately, this message was not more specific. To clarify, you just need to wait and see what the official release date for Huawei Mate X will be.
Are you planning to buy a new premium phone? There are reasons why it's better to wait before buying a premium phone right now. Which? Here are some of the main reasons. What the buyer can expect from premium phones in 2019 is a new Qualcomm Snapdragon 855 mobile chip, new super fast 5G connectivity, foldable screen design and a 48-megapixel mobile camera.
All about phones and buying them: If you are planning to buy new phone premium class, wait at least one month to purchase. And here's why:It is expected that at the Mobile World Congress 2019 (also known as MWC 2019), which will be held in just a couple of weeks (on the twentieth of February), most of the leading smartphone companies will present their latest flagship phones with advanced features and updated technical specifications.
So, new cell phone specifications for this year.
Samsung will release a multimedia phone Galaxy S10, while manufacturer HMD Global will present a five-camera Nokia phone 9 PureView. Phone manufacturers Huawei, Oppo and LG will also present their latest mobile devices at the upcoming mobile exhibition.
But in 2019, buyers need to think about more than just the next model upgrade cycle when purchasing a new premium phone. And the reasons for this are the unique technical characteristics in the description of the phones.
- Qualcomm Snapdragon 855 processor.
Qualcomm's top-end processor powers most premium phones, from Samsung models Galaxy S9 to OnePlus 6T. Snapdragon processor 845 is now history. The latest Qualocmm Snapdragon 855 chipset based on 7nm process technology delivers better performance, higher battery efficiency and built-in artificial intelligence (aka AI) processing.
Paired with the Snapdragon X50 modem, the Snapdraon 855 will also bring 5G mobile connectivity to premium smartphones in 2019.
Other key features of the chipset include improved gaming performance ( GPU Adreno 640), artificial intelligence and a higher resolution camera, as well as an in-display fingerprint sensor.
- 48 megapixel camera.
The latest premium smartphones are expected to come with a higher resolution camera. The 48MP camera is the new rage and has already been on several phones such as the Honor View20 and Redmi Note 7 have a similar function.
Although the resolution is certainly not best measurement For camera evaluation, the built-in sensors are also greatly improved. Most of these 48MP camera phones are likely to use the Sony IMX586 sensor, dubbed the highest resolution camera sensor for mobile phones.
In addition to better camera resolution and sensors, mobile phones The premium 2019 may also come with Samsung-like quad and penta camera setups (five). Most 2018 phones featured dual cameras with a primary camera while the secondary camera ranged from ultra-wide, depth to monochrome.
We expect the new phones to feature most of these sensors with three, four or five cameras.
- Fifth generation mobile communications: 5G.
The evolution of mobile networks continues! The upcoming MWC 2019 will also be a launching pad for 5G phones. Xiaomi, OnePlus, Samsung and almost all the leading players in the mobile market are expected to introduce their new phones with 5G connectivity. Most of these phones will also hit the European and US markets later this year. Some Apple fans already want to buy an iPhone 5G. For other countries, the rollout of 5G networks may be delayed by at least one year. But investing in a 5G phone right now wouldn't be a bad idea.
- Folding mobile phone.
Folding phones are no longer a concept, screen folding is already part of the features of mobile phones. Korean company Samsung introduced its first foldable phone late last year. It is expected to unveil the commercial version of the phone at its event on February 20, ahead of the MWC 2019 mobile expo.
Samsung is likely betting big on the new form factor, as it plans to release at least one million foldable phones this year. Considering that Russia is one of the priority markets, we can expect that foldable phones will also be released. Apart from Samsung, Huawei, Xiaomi and Oppo have plans to launch foldable phones this year.
- Artificial intelligence in phones, plus don’t forget about machine learning.
Google introduced operating system last year Android system 9 Pie. Android Pie features like Adaptive Display and Adaptive Brightness are powered by machine learning to help improve your user experience. Android phones. Going forward, artificial intelligence and machine learning will become an important part of updates to the Google Android platform. It may be worth making sure that your new phone will be compatible not only with Android 9 Pie, but also with the Android Q successor.
Besides Google, phone companies like Xiaomi and Asus are embedding artificial intelligence (AI) and machine learning (ML) directly into system apps. The camera, for example, on premium phones uses AI and ML to automatically recognize scenes and automatic optimization settings. Most of the 2019 mobile phones will come with AI-enhanced cameras.
The only thing that remains a dream when buying is when the best mobile phones will have a full-fledged “3D phone” feature.
News added:
1) Samsung has released the latest version of Galaxy S10 and people believe that iPhone may lose its position as the king of smartphones.
The latest flagship smartphone Samsung Galaxy S10 was released by the company on February 20. On this day, Samsung presented many new products. The audience was really interested in the new phone demonstrated. So much so that they say that Apple's iPhone has a serious alternative. Latest model Samsung's Galaxy S10 surprised and shocked fans, in a good way.
2) The attractive, powerful and incredibly expensive Huawei Mate X foldable 5G phone.
Following the announcement of the first folding smartphone Samsung Galaxy Fold, the Chinese company Huawei is betting on the folding screen form factor and announcing the release of Huawei Mate X, which also works with 5G communications. Developer Huawei is taking a completely different approach compared to Samsung, namely placing the smartphone's rollable display on the outside rather than on the inside, and this solution has a number of pros and cons when describing next-generation phones. The price of Huawei Mate X starts from 2299 Euro.
3) Will Apple release a foldable iPhone?
Some analysts believe that a foldable iPhone could be in the works from the Cupertino company. Then, if the new Apple smartphone comes out with a folding screen, it has a chance to become the best among the foldable ones already released Samsung smartphones Galaxy Fold and Huawei Mate X.

Video review of the VideoSolo DVD Creator program: User's Guide.
I was inspired to create this article by two things: numerous speculations by marketers and specialized journalists on the topic of screens; and a bunch of absolutely identical comment threads under smartphone reviews with absolutely identical discussions about which matrices are better. Usually, the hottest thing happens under reviews of Chinese phones with OLED screens. I’m tired of fighting windmills, communicating with each reader individually, in this material I decided to dot all the i’s and dispel numerous myths about modern screens, looking ahead I will say that the emphasis will be on the confrontation between IPS and AMOLED matrices. Most likely, most of you will not see anything new in what has been written; you will not receive sacred knowledge here, nor will you be stripped of your veils. I will talk about obvious things that neither bloggers nor journalists want to talk about. The guide is designed for adequate thinking people; convinced fanatics can go about their business.
Definition of the term “screen”
Before getting to the point, we need to define the term screen and clarify its functional purpose. Wikipedia tells us that a screen or display is electronic device, designed to visually display information. If we try to give a less laconic and more modern definition of the screen from the point of view of functionality and with an emphasis on consumer properties, it will turn out something like this: a screen is a device whose task is to display as accurately and in detail as possible all kinds of content and the user interface of operating systems and applications such how the authors intended them. Physical resolution is responsible for “maximum detail”, otherwise: the number of smallest screen elements (picture’s elements) or simply pixels (pixels), the higher the resolution the better, ideally it should be infinitely large. “As accurately as possible” are responsible for such parameters as: color accuracy and contrast, or the ratio of the lightest and darkest point on the screen. Secondary parameters that do not directly affect the accuracy or detail of information display, but affect the consumer properties of the screen, include: maximum brightness, picture distortion when the view deviates from perpendicular, reflectance, picture refresh rate, response time, energy efficiency and some others . Of particular note is such a parameter as color gamut - the most important parameter for professional monitors and practically meaningless for devices intended for consuming content. But it is the color gamut that has been the subject of much speculation by manufacturers of mobile gadgets in recent years. Let's clear up this murky topic before moving on.
What is color gamut and why is it the subject of much speculation?
You need to start with the fact that any image is encoded when captured and stored in the memory of a photo or video camera. Artificially created pictures and clips, as well as parts of the graphical user interface of operating systems and applications, are initially encoded in a similar way. In both cases, color information is represented using a color model - a special mathematical tool for describing color using numbers or, more precisely, coordinates. The most common is the three-dimensional RGB model, in which each color is described by a set of three coordinates responsible for one of the colors: red, green and blue; the displayed hue depends on the brightness ratio of each component. Modern screens are capable of displaying only part of the spectrum of colors and shades visible to humans; color gamut literally means how large this “part” is. Due to such limitations, a person is forced to create standards of presentation color spectrum based on the capabilities of existing screens. So in 1996, to unify the use of the RGB model in monitors and printing, HP and Microsoft developed the sRGB standard, which used the primary colors described by the BT.709 standard, common on television at that time, and gamma correction designed for monitors with cathode ray tubes. It is important to understand that such unification allows, albeit with some reservations, to guarantee that the creator and consumer of content on their screens will see approximately the same thing. Subsequently, the sRGB standard became widespread in all areas of content production, including the creation of Internet sites. Of course, there are other standards for representing the color spectrum, such as Adobe RGB, which has a much wider color gamut, but today the vast majority of content is encoded in accordance with sRGB.
What happens if sRGB content is viewed on a screen with a wider color gamut without adaptation? The coordinates of the sRGB space will be transferred to the coordinate system of the color space of such a screen, as a result of which colors will appear more saturated than they actually are, in some cases the shades will be distorted so much that orange will become red, light green green, and blue blue. Conversely, if content with a wider color gamut is viewed on an sRGB screen, the coordinate shift will cause the colors to appear less saturated than they should be.
We all know that the screens of most modern flagship smartphones have an expanded color gamut relative to sRGB, how does this affect their consumer properties? If this is a smartphone or tablet on Android, then three options are possible. In the best case, the shell settings will contain preset color profiles, among which there is one that brings the space to the sRGB standard, an example would be MIUI or the shell from Samsung. But even in this case, applying profiles on the fly is impossible, and the user will have to choose between an expanded color gamut and correct color rendition. The second option is when the system does not have built-in profiles, but in the developer settings you can activate the sRGB mode, for example, this can be done on Google smartphones Pixel and OnePlus 3T. Unfortunately, the operating system GUI becomes faded when sRGB mode is activated, as it is coded according to the color gamut of their screens. In the third worst case scenario, the user will not find any profiles in the system and, accordingly, will not receive any choice; he will be left to enjoy oversaturated colors. But in personal computers running Windows and MacOS there is no such problem, since both systems not only support color profiles, but can also “on the fly” convert colors from one space to another, that is, regardless of what content and on what screen will be displayed, the user, with some reservations, will see the colors as the author intended them. A similar color profile management system is available in iOS. Manufacturers, either for the sake of beautiful numbers on the specifications page, or just for the sake of it, continue to install IPS and OLED screens with an expanded color gamut in flagship models, despite the fact that there is no need for this, since 99% of the content complies with the sRGB standard and the situation is unlikely to change radically in the near future. There are simply no tasks that such screens can perform in devices designed for content consumption. All this would make at least some sense if Google added color profile management to Android, as Apple did, but at least in 2017 we won’t see this. The irony is that the problem is created by empty space, and no one is in a hurry to solve it.
Liquid crystal screen: operating principle; advantages and disadvantages
Twenty years ago, most monitors and televisions were equipped with screens based on cathode ray tubes; they were soon replaced by liquid crystal displays or LCD (liquid crystal display), which over time received several branches of development and today there are three technologies for the production of liquid crystal matrices screens: TN, MVA and IPS, the latter, due to a successful combination of advantages and disadvantages, has become dominant in the mobile technology segment. Principle LCD operation is simple, some details may vary depending on the production technology, but a typical matrix includes a backlight lamp and six other layers. The first thing behind the lamp is a vertical filter that polarizes the light accordingly. Behind it are two layers of electrodes with a layer of liquid crystals located between them; the voltage applied to the electrodes orients the crystals and they refract the light so that it passes or does not pass through the next layer - a horizontal polarizing filter. The last one is a color filter - red, green or blue. Liquid crystal screens are lighter, more compact and more energy efficient than their predecessors, but they also have a number of serious drawbacks, in particular low contrast and black depth, and even limited color gamut potential, which depends on the imperfection of the backlight. In addition, brightness and contrast may deteriorate if you look at the screen at a different angle.
Organic LED screen: advantages, disadvantages, PWM, Pentile
Relatively recently, LCD has a serious competitor - these are screens with active matrix organic light-emitting diodes or AMOLED. Such screens are fundamentally different from LCDs in that the light source in them is not a backlight lamp, but each subpixel separately, which gives AMOLED many advantages over liquid crystal screens, the main ones being: almost infinite contrast; less power consumption when displaying images with a predominance of dark tones; potentially wider color gamut; and smaller dimensions. The first AMOLED screens, in addition to their advantages, also had significant disadvantages, including: inaccurate color rendition; rapid burnout of LEDs; high power consumption when displaying images with a predominance of light colors; flicker due to pulse width modulation; and most importantly the high cost of production. Over time, most of the shortcomings were overcome or reduced to a minimum, except for PWM, which to this day is the Achilles heel of the technology. Pulse width modulation, or PWM, is one way to adjust the brightness of LEDs, which has the side effect of causing the screen to flicker at a certain frequency. Most people are not susceptible to this kind of flicker, but for some users, PWM can cause rapid eye fatigue and even headaches. It is important to note that the flickering effect is completely absent at brightness values close to maximum and begins to appear at brightness levels of 80% and below.
It is impossible to ignore the topic of organizing subpixels in screens based on organic LEDs; the fact is that in most AMOLED matrices, subpixels are arranged according to the RGBG scheme, when a pixel does not consist of three subpixels like a typical LCD screen, but of four: red, blue and two green, this scheme is also called Pentile. The manufacturer (Samsung) considers the physical resolution of such screens to be exactly two times less in terms of the number of green subpixels, red and blue subpixels in the matrix. Obviously, to obtain a shade you need at least three full-fledged subpixels. Thus, the effective resolution of such screens is not equal to the nominal resolution specified in the official specification. For example, for a QHD screen, the nominal resolution is 2560*1440 pixels, the resolution based on the number of red and blue subpixels will be approximately 1811*1018:
The effective resolution of such a matrix, taking into account the clever interpolation algorithms embedded in the screen controller, is somewhere between 1811 * 1018 and 2560 * 1440, we can assume that it corresponds to FullHD resolution in RGB matrices. It may very well be that it is precisely for this compliance that Samsung has been choosing QHD resolution for its flagship smartphones for many years in a row.
Detailed comparison of IPS and AMOLED using the example of iPhone 7 and Galaxy S8 smartphone screens
Now that we have learned everything about the characteristics of screens and the features of different types of matrices, we can move on to the main question: which technology is better? I’m sure it’s correct to try to answer this question by comparing the best AMOLED and IPS matrices available today, namely the screens of the Samsung Galaxy S8 and Apple iPhone 7 smartphones. Since I have not yet acquired testing equipment, I will analyze the test results taken from a reputable resource. Let's start with the resolution, the Galaxy S8 screen has 2960*1440 pixels, the guaranteed effective resolution will be 2094*1018, the guaranteed effective pixel density will be 403 per inch. The iPhone 7 Plus has a lower nominal effective resolution: 1920*1080, and an effective pixel density of 401 per inch. The advantage is obvious in favor of the screen from the Korean vendor. The resolution of both screens is enough for everyday use and not enough for comfortable use with virtual reality helmets. Next, let's move on to accuracy; the contrast ratio of the Galaxy S8 is almost infinite. The iPhone 7 has a stated contrast ratio of 1400:1, but the actual contrast is slightly higher – 1700:1; this contrast is more than enough for comfortable viewing of content. It turns out that in this parameter the screen of the Galaxy S8 was ahead. As for color accuracy, both smartphones showed virtually identical results; color errors in the Galaxy S8 and iPhone 7 can be safely ignored. You can see the most important secondary characteristics in my opinion below:
Parameter | Samsung Galaxy S8 | Apple iPhone 7 |
Efficient resolution, bigger is better | 2094*1018 | 1920*1080 (iPhone 7 Plus) |
Effective pixel density per square inch, bigger is better | 403 | 401 (iPhone 7 Plus) |
Contrast, bigger is better | endless | 1400:1 |
Average color accuracy sRGB / Rec.709 JNCD, very good if less than 3.5 | 2,3 | 1,1 |
Maximum brightness, bigger is better | 1020 nits | 705 nits |
Minimum brightness, less is better | 2 nits | 3 nits |
Ambient light reflectance, less is more | 4,5% | 4,4% |
White point D65, standard 6500K | 6520 K | 6806 K (colder) |
Brightness drops when the gaze is deviated by 30°, better when less than 50% | 29% | 54% portrait mode; 55% landscape mode. |
Contrast at 30° gaze deviation, more is better | endless | 980:1 portrait mode; 956:1 landscape mode. |
Maximum power consumption, less is better | 1.75 watts at 420 nits, at 13.1 in² white fill | 1.08 watts at 602 nits, at 9.4 in² |
As for the color gamut, the iPhone 7 is ahead here, since it can display the colors of the DCI-P3 space or 126% of the sRGB field, while the user does not need to sacrifice color rendition; the content is displayed based on the color profile embedded in it. The Galaxy S8 screen has an even wider color gamut - approximately 142% of the sRGB field, but does not have color profile management, driving the user into a corner, that is, into the Main mode, which corresponds to 100% of the sRGB field.
So what's the bottom line? If we consider screen technologies in isolation from the final product, then AMOLED today is superior to IPS in almost everything, although it still has problems with PWM and high power consumption. Without any doubt, OLED matrices are the future. Unfortunately, due to Android restrictions their potential has not yet been fully realized. When comparing ready-made solutions in the form of Galaxy S8 and iPhone 7, the slight superiority of the latter due to honest DCI-P3 and standard other parameters is obvious. I would like to warn you against projecting the results of the above comparison onto absolutely all IPS and AMOLED screens. There are a lot of good, average and bad matrices on the market, and each case needs to be analyzed separately. Online publications focused on technical detail and reliability will help us with this; among such publications I would include the already mentioned, anandtech.com and some other sites, from Russian-language sites - ixbt.com.
Perhaps you shouldn’t take the consumer properties of screens too seriously, because objective information is almost always superimposed on the factor of subjective perception. For example, in Southeast Asia there are a lot of people who like unnatural, oversaturated colors; in our country there are also quite a few such people. On the other hand, broadcasting information poured into the ears by marketers in numerous discussions under reviews on YouTube is at least strange. Finally, I’ll be Cap and give you a couple of banal pieces of advice: don’t stop thinking and be critical of any information you receive from brand representatives and the media, know how to analyze data and check facts, or just read resources and watch bloggers you can trust.
In this article I will not go into the technical details of creating IPS and AMOLED matrices, they are not so interesting in this case. What is more important is what the average consumer gets when choosing this or that matrix. Therefore, in this material I will talk about the practical advantages and disadvantages of these two types of matrices.
Benefits of IPS
IPS matrices are an evolutionary development of TFT displays, but with a number of specific advantages. Firstly, they have much better color reproduction; the picture on IPS is much brighter and richer. Secondly, they have much higher viewing angles; when deviated, the picture does not fade. The overall brightness level of IPS panels is also superior to conventional TN displays. The last advantage is natural white color, which is quite problematic to achieve on AMOLED.
Advantages of AMOLED
AMOLED matrices are produced by Samsung and were initially used only by it, but later other manufacturers also gained access to such displays.
The first advantage of AMOLED matrices is the natural black color; on both IPS and TN matrices, the black color is more like gray, especially at maximum brightness. With AMOLED, you get perfect blacks, and the added bonus is reduced power consumption when displaying them.
The second plus is the high contrast of the picture. Many users love AMOLED displays for their bright and rich colors. Any picture looks very cool on such screens.
The third advantage is the high level of maximum brightness. In a direct comparison, on a bright sunny day, the AMOLED matrix will outperform IPS.
The fourth advantage is low power consumption. Smartphones equipped with IPS screens will discharge with an active screen much faster than their counterparts with AMOLED
Disadvantages of IPS
Perhaps the only drawback of IPS matrices is their imperfect display of black colors. Otherwise, these are excellent displays with natural color reproduction, maximum viewing angles and good brightness levels.
Disadvantages of AMOLED
AMOLED displays have a special pixel structure that uses a larger number of green subpixels; this solution has one significant drawback called PenTile. When reading small text, you may notice red halos around the letters, which some people find annoying.
The second disadvantage is PWM (pulse width modulation). Its essence is that individual pixels turn on/off at a very high speed, visually indistinguishable by the human eye. This is done to reduce power consumption, but in fact the eyes get tired faster from such displays. Because of this, such displays on the camera may flicker.
Conclusion
And yet, despite the disadvantages listed above, it is AMOLED displays that are installed in the flagships of most large companies. The thing is that, all other things being equal, they show a brighter and juicier picture, as well as better behavior in the sun.
IPS matrices are also good displays, so Meizu installs them in most mid-segment smartphones, and leaves AMOLED for flagships.
Which technology is better - IPS or Amoled? We talk about the advantages and disadvantages of screens. How to make the right choice?
There was a time when the Samsung company loudly announced its Amoled technology, calling it almost the pinnacle in the production of matrices. Initially, Amoled screens were used in televisions, then the technology was inherited by the brand’s smartphones.
AMOLED displays are not liked for their unnatural picture, excessively high contrast, and saturated colors.
At this moment, IPS screens with their clarity and natural picture appear on the market. Which is better - IPS or Amoled, and which display is right for you.
Advantages and disadvantages of IPS and AMOLED
Both technologies have a lot of them, that’s a fact. Let's start with Amoled.
AMOLED – Active Matrix Organic Light Emitting Diode. The technology provides maximum screen brightness and high image contrast, excellent glare suppression in bright daylight/sunlight/lamp light. At the same time, the screen itself consumes little energy, since the pixels are activated only at the right moment, while with IPS all pixels are constantly active when the screen is turned on.
Disadvantages of Amoled:
- High cost of production, which significantly increases the price of a smartphone;
- High vulnerability to mechanical damage;
- Over time, colors fade.
What does IPS have? Here, too, everything is very ambiguous. In-Plane Switching technology was created as an ideological successor to TFT - a frankly outdated technology that does not provide a juicy picture, or good responsiveness, or wide angles review.
Having gotten rid of these shortcomings, IPS became a real godsend. The picture is clear, dynamic, deep and rich. But most importantly, the colors have become truly realistic. Amoled, with its oversaturated color palette, loses greatly in this regard. Although, this is also a matter of taste. The picture is clear, the viewing angles are excellent - everything is great.
Disadvantages of IPS:
- Active energy consumption;
- Smartphones with IPS screens are slightly thicker than their Amoled counterparts;
- IPS requires more powerful backlighting;
- Slow matrix response (only the most picky users will be able to tell the difference);
- Pixel grid visibility.
AMOLED or IPS - what to choose?
If you are faced with a choice - buy a smartphone with IPS or Amoled screen, start from how exactly you will use it and what you generally expect from the screen. Do you want natural colors and overall good color rendition? Choose IPS. Do you want the battery to last longer, and the picture to delight you with richness and depth? Amoled for you.
At the same time, everyone should remember that you are not buying a TV, but a smartphone. The average user may not notice much difference between these technologies. And perhaps best advice in choosing - just see what you like best visually. Well, if you are buying a phone for several years, then it is better to buy one with an IPS matrix. You definitely won't like the faded colors on Amoled. Although, again, you may not even notice them.
Screens with OLED, AMOLED and even Super AMOLED matrix “burn out” over time. If the same pixels are illuminated on the screen for a long time, they will dim and this will be clearly visible. Typically, virtual navigation buttons, icons in the top bar and a clock are printed. The display cases of smartphones displayed in stores suffer the most from this problem. They are turned on almost around the clock, stand on stands for weeks or months and always show the same demo content, which remains on the matrix forever.
What is causing this problem?
The essence of the problem is in the key feature OLED technology. The matrix consists of LEDs of three colors (blue, red and green), and different types diodes have their own service life. Subpixels blue less bright, so to maintain color balance, they are supplied with more current than the red and green subpixels. Because of this, the service life of blue diodes is reduced, over time they shine dimmer, and the color rendition of the screen goes into red and green shades.
Burnout occurs in areas where blue or white color is used heavily. Black color does not use the pixel backlight, so it does not cause burn-in. Burnt-in pixels become dark and visible on the screen. The lighter the image, the better they are visible.
Is there a solution?
Manufacturers have not come up with an adequate solution to this problem; they either ignore it altogether or use crutches, providing for periodic displacement of static elements of the operating system interface by several pixels. Users may not notice this shift, but it prevents subpixels from overheating and slows down their deterioration. The matrices of some Samsung smartphones use PenTile technology: blue diodes have larger size and glow quite brightly with less current, which increases their service life.
How to avoid burnout?
Burn-in occurs most quickly on a bright screen, so you shouldn’t unnecessarily turn the brightness slider to maximum.
Do not leave your smartphone on with a static image for long periods of time.
Use a dark, or better yet black, theme for your applications and keyboard.
If your smartphone supports themes, change them from time to time.
Change the wallpaper and icon layout on your home screen occasionally.
Do not use your smartphone as electronic watch. There are applications that allow you to display the time on the screen, and a few hours of work in this mode is enough for the pixels under the numbers to burn out.
Is it possible to fix a screen with burnt-out pixels?
Diodes do not recover, so it is impossible to remove burnout from the screen. Some people advise leaving the screen in the sun for a couple of hours. After such a procedure, the burnt-out pixels may not be visible, but not because they have been restored, but because the remaining subpixels have also darkened. If your smartphone is uncomfortable to use due to marks on the screen, it makes sense to take it to a workshop and ask them to replace the matrix or do it yourself.
