How to select a matrix by serial number? How to choose a suitable matrix for your laptop Which matrix to choose for a laptop

If this is your first time encountering a problem such as a matrix malfunction on a laptop, and you don’t know what to do or how to choose the right matrix to replace, you can find out the answers to your questions by reading this article.

The matrix for a laptop is not just an important component, it is an element that is recognized as fundamental, providing information output to the device screen. The matrix requires careful handling and does not tolerate rudeness and sloppiness. The answer to such inattention will be a breakdown, and in order to return the laptop to its former power, you need to know how to choose a matrix for the laptop.

Matrix

The laptop matrix is ​​a liquid crystal screen consisting of several required parts:

backlight lamps;

polarizers;

reflectors;

glass substrate equipped with conductive contacts;

liquid crystals;

second polarizer;

second substrate.

One of the most important characteristics is the matrix resolution, which depends on the number of pixels. The flat surface of the matrix allows you to get rid of such phenomena as glare on the screen.

But the main characteristics of the matrix are recognized:

Diagonal (corresponds to the diagonal of the laptop screen and is measured in inches).

The screen format is the ratio of the side of the matrix to its top or bottom side. The usual laptop screen format is 4:3 or 5:3, but there is a widescreen screen with a 16:9 ratio.

Matrix resolution characterizes the number of pixels. The higher the resolution, the clearer the image received on the screen will be.

The matrix coating can be matte or glossy. The use of a glossy surface requires anti-reflective protection.

Brightness and contrast are adjustable indicators of image quality.

Viewing angle and response time. The faster the response time, the clearer the picture on the screen.

If a breakdown occurs

If, due to unforeseen or any other circumstances, the laptop matrix fails, you should not try to repair it. The damaged screen must be replaced immediately. But this is just at first glance. The most important thing is to choose the right matrix for your laptop.

What do you need to know to perform a replacement without damaging the device? First of all, you need to understand that you can only buy a suitable display if you know exactly all the most important characteristics. The fact is that some matrix models have different types of backlighting and resolution, but sometimes even the diagonals are different. In order to understand how to choose a matrix for a laptop according to the model, it is important to know exactly all the characteristics of the original and choose a new device so that its dimensions fully correspond to the previous ones.

Selecting the matrix

You can verify the accuracy of the dimensions and other characteristics only by performing certain manipulations:

Remove the matrix from the laptop and inspect its back side. There should be factory stickers with numbers indicating part number codes. In them, the manufacturer indicated information about the manufacturing plant and the diagonal of the matrix.

Check in the accompanying documents what the diagonal of the matrix is.

Find out what type of backlight was used in this device. The backlight can be either lamp or LED.

Set the type of connector to which the cable is connected. It is designed to connect the motherboard and matrix decoders. The most common are 30 or 40 Pin.

Determine the availability of fasteners necessary to install the matrix. There are laptop models that do not have these mounts.

When thinking about how to choose the right matrix for a laptop, it is important to remember that when choosing a model of interest, you need to pay attention to the five parameters mentioned above. If they do not match, the purchase will be in vain. And, of course, it’s easier to entrust the replacement process itself to a specialist. Read our article on how to replace the matrix yourself.

How to choose the right matrix for a laptop?

Attention! Some laptop models have matrices with different types of screen backlighting, resolution and even matrix diagonal. For example, a Dell M1330 laptop may have CCFL (lamp) or LED (light-emitting diode) backlighting. The Compaq R3000 comes in two different screen sizes: 15″ or 15.4″. Macbook Pro 15″ may have different matrix resolutions and they are not interchangeable.
You must make sure that the matrix you choose in our store suits you in size, resolution and backlight.

As a rule, manufacturers do not share information on matrix compatibility with each other, and even those who write on their web pages can be wrong, so the only way to buy a 100% correct display is to make sure that the size, resolution, and backlight are the same just like the original screen.

How to choose the right matrix?

1. First you need to remove the matrix from the laptop and look at its back.

2. Factory stickers with codes (part numbers) will be visible on it.

3. In the part number, the manufacturer encrypts information about the diagonal and the factory.

For example, a matrix with part number CLAA 101NB 01A , it follows that the diagonal of the matrix is ​​10.1 inches, and the manufacturer of the matrix is ​​CHUNGHWA.

Now you can use the search on the website partsdirect.ru or call 495-223-23-05 to obtain information about the availability of the required matrix or its interchangeable analogue. Our store has a huge assortment of matrices, so choose and buy the right matrix in Partsdirect it won't be difficult.

For ease of searching, we attach a list of matrix manufacturer abbreviations:

Just a few years ago, the choice of a monitor for a personal computer was based on the price category, where it was clear that a more expensive device had a high-quality matrix, and a cheap monitor did not shine with characteristics. At the moment, the monitor market is divided by screen size; each manufacturer produces devices with different matrix technologies. Because of this, the purchasing choice has become more complicated. This article will help users choose the right monitor matrix type. Which screen is better to buy on the market, for what purposes and how it differs from competitors will be presented in an accessible form.

To make it clearer

Before choosing the type of monitor matrix, you need to understand the principle of its operation, as well as identify all the advantages and disadvantages. Having compiled a list of needs (for what purposes this device is purchased), it will be very easy to compare what is actual with what is desired. If you do not affect the screen size, the use of the monitor is distributed according to needs into several groups:

1. Office monitor. A high contrast level is the only requirement.
2. Designer's computer (photo, pre-press). Accurate color reproduction is important.
3. Multimedia. Watching movies requires wide viewing angles and true black color on the screen.
4. Gaming computer. An important indicator is the response time of the matrix.

The production technology and the movement of electrons between matrices is unlikely to be of interest to anyone, so this article will discuss the advantages and disadvantages, and also use data from the media - reviews from owners and recommendations from sellers. Having found out what technologies exist, all that remains is to combine them with the stated requirements and the funds allocated for the purchase of the monitor.

The state employee does not give up positions

The TN (Twisted Nematic) monitor matrix type is considered a long-liver among its competitors on the market. Due to its low price and availability, monitors with this matrix are installed in all government and educational institutions, offices of many companies around the world and in large enterprises. According to statistics, 90% of all monitors in the world have a TN matrix. Along with the price, another advantage of such a monitor is the short response time of the matrix. This parameter is very important in dynamic games, where rendering speed plays a paramount role.

But the color rendering and viewing angle of such monitors did not work out. Even upgrading the TN matrix by adding an additional layer to increase viewing angles did not give the desired results; it only added “+film” to the name of the screen type. We must not forget about energy consumption, which significantly exceeds the operating mode of all competitors.

And yet

Apart from office use, TN+film is the best type of monitor matrix for gaming. After all, most gamers prefer to overpay for high-performance components such as a processor or video card, but they can save money on the screen. However, do not forget about color rendering; in modern games, developers try to make the plot as realistic as possible, and without a real rendering of all colors and shades, this will be very difficult to achieve.

As a result, apart from the low price and short response time, the TN matrix will not be able to surprise a potential buyer with anything. After all, it is very difficult to ignore the shortcomings:

1. Low color rendering with the inability to display perfect blacks. The defect is visible when watching dynamic films where all the action takes place in the dark - “Van Helsing”, “Harry Potter and the Deathly Hallows”, “Dracula” and the like.
2. The low cost of production leads to a high probability of acquiring a defective matrix, the dead pixel of which is immediately visible, because it is painted white.
3. Very low viewing angles do not allow you to contemplate the picture on the screen with a large family.

A step in the right direction

The monitor matrix type VA (Vertical Alignment) uses technology with vertical ordering of molecules, and in the post-Soviet space is better known under the MVA or PVA markings. And more recently, the suffix “S”, which stands for “Super,” was added to the existing modifications, but the monitors did not acquire any special characteristics compared to their competitors, except that they became slightly more expensive.

VA technology was intended to eliminate defects in TN+film matrices, and manufacturers were able to achieve certain results, but when comparing these two screens, the user will find that they have opposite characteristics. That is, the disadvantages of VA matrices are the advantages of TN, and the advantages of VA are the disadvantages of cheap matrices. What the manufacturers were thinking is unknown, but the situation on the market has not yet changed for these matrices, even with the introduction of the “Super” label.

Advantages and disadvantages of VA technology

If VA technology is compared with the cheapest matrix on the market, TN+film, then the advantages are obvious: excellent viewing angles, very high-quality color reproduction with deep blacks. In fact, this type of photo monitor is the best in its price range. The only thing that confuses me is the response time. Compared to a cheap TN screen, it is several times higher. Naturally, a device with such a matrix will not be suitable for game lovers, since the dynamic picture will be constantly blurred.

But designers, layout designers, amateur photographers and all professionals who need to work with real color and its shades will like monitors with VA technology. In addition, the wide viewing angle, even with a strong tilt, does not distort the image on the screen. Such monitors are suitable for multimedia - watching any movies with your family will be interesting, because the screen provides the opportunity to see real black color, and not its semblance in the form of fifty shades of gray.

No flaws?

IPS matrices and their various modifications have been on the market for quite a long time. However, their cost is not as attractive to buyers as the impeccable characteristics of screens that use an expensive type of monitor matrix. Only Apple knows which screen is better for a businessman and designer, the president of a company or a traveler, because all of its devices, without exception, have IPS (In-Plane Switching) matrix technology.

From year to year, all kinds of technologies appear, experts are trying to improve the quality of an already expensive and high-quality matrix, as a result of which there are a number of modifications on the market: AH-IPS, P-IPS, H-IPS, S-IPS, e-IPS. The difference between them is minor, but it is there. For example, e-IPS (Enhanced) has technology that increases screen contrast and brightness, and also reduces response time. The professional P-IPS series can display 30-bit color, but it’s a pity that the user will not clearly notice this.

Reach your dreams

Without going into deciphering the modifications of the IPS matrix, you can see that this technology is a kind of symbiosis of VA and TN+film production. Naturally, only the advantages were selected that were embodied in one device. For example, the type of monitor matrix AH-IPS (Advanced High performance) is a direct competitor to plasma panels, which have no analogues in the world in terms of high-definition image reproduction quality. Such a serious statement was made back in 2011, but apart from the inflated price for a device with an AH-IPS matrix, it has not yet been possible to prove its superiority.

And yet, if a game lover has a question about which type of monitor matrix to choose - IPS or TN, then the right decision would be to purchase a more expensive and high-quality screen. Even though the price of the device is several times higher than its cheap competitor, spending time with your favorite toy will be more interesting. After all, realistic picture quality will always remain in first place.

Fun games manufacturers

We will talk primarily about the Korean giant Samsung, which constantly strives to invent new technology, but it does not always succeed, because along with the quality, the buyer is also interested in the cost of the device, which for some reason tends to increase disproportionately.

By introducing single pixel separation technology, Samsung has achieved better image clarity. This is primarily noticeable on the screen when typing multi-colored text in small font. The technology was approved by many layout designers, and PVA-labeled monitors quickly found fans.

The WVA monitor matrix type was an improved version of technology from Samsung, and, judging by the low cost of the devices, it competed freely in the market. The shortcoming with the matrix response speed in all devices created using VA technology has not been eliminated.

Radical solution

The type of monitor matrix AH-IPS was of interest only to buyers in developed countries of the world. After all, for the best quality you have to pay a very large amount, which is beyond the means of residents of the post-Soviet space. And there is no point in purchasing a monitor that is slightly more expensive than a modern personal computer assembly. Therefore, manufacturers of expensive devices had to reduce the cost of technology by reducing the quality in the production of components. This is how a new type of monitor matrix PLS (plane-to-line switching) appeared on the market.

After analyzing the characteristics and studying the operating principle of the new matrix, you might think that this is just an improved modification of the PVA matrix from Samsung. That's true. As it turned out, the manufacturer developed this technology a long time ago, but its implementation occurred quite recently, when there was a huge price difference between middle-class and expensive devices, and there was an urgent need to fill the empty price niche.

Who won?

Apparently, this is the only case when in the war between manufacturers for the sales market, the buyer wins, who receives a worthy device in terms of its characteristics at a price that is quite acceptable to him. The disadvantage is the small selection of manufacturers, because Samsung has not released the technology beyond its concerns, so the Korean brand has few competitors - Philips and AOC.

But, faced with the choice of which type of monitor matrix is ​​better - IPS or PLS, a potential buyer who decides to save money will definitely give preference to the latter. After all, in fact, there is not much difference between the devices. And if you pay attention to the fact that most mobile devices, including tablets, have a PLS matrix, which is very often presented by the seller as a more expensive IPS, then only one conclusion suggests itself.

In pursuit of perfection

Not long ago, Sharp introduced a type of monitor matrix made using IGZO (indium, gallium and zinc oxide) technology. According to the manufacturer, the material has very high conductivity and lower power consumption, resulting in a higher pixel density per square inch. Essentially, IGZO technology is suitable for the production of 4K monitors and all mobile devices produced in Ultra HD format.

The technology is far from cheap, and prices for monitors and TVs with IGZO matrix are breaking world records. However, the well-known company Apple got its bearings very quickly, concluding contracts with the matrix manufacturer. This means that this technology is the future; all that remains is to wait for the price to drop on the world market.

Best choice for gamer

Having studied existing production technologies, you can without hesitation determine which type of monitor matrix is ​​better. For games, response time and color rendition are a priority, so the choice here is limited. For those who want to save money, a device with a PLS matrix is ​​quite suitable. Although the choice among manufacturers is small, it is possible to decide among the modifications. In addition to the standard type of matrix, the manufacturer offers an improved Super-PLS model, in which the brightness and contrast are higher, and the screen allows you to display a resolution exceeding FullHD.

But if the price of the issue is not critical for the buyer, then an IPS screen will allow you to enjoy the most realistic picture. You won’t be able to get confused by the markings, because they all boil down to improving the viewing angle and dynamic contrast. The only difference is the price - the better, the more expensive. By giving preference to a device with an IPS monitor matrix type, a gamer will not go wrong.

Photo processing and graphics are a priority

It is clear that an IPS device is suitable for designers and layout designers. But is there any point in overpaying? After all, photo processing and layout involve working with colors and their shades. The response time of the matrix is ​​not considered at all. Professionals recommend not to waste money and choose a VA type of monitor matrix. Yes, this is old technology, yes, this is the last century, but in terms of “price-quality” criteria, matrices of this type have no competitors. And if you want to purchase some of the new products, then you can opt for a PLS matrix.

If there is a need to work on a high-resolution monitor, for example 4K, then professionals recommend giving preference to IGZO devices. Their price is not so far from the popular IPS screens, but they are undoubtedly better in quality.

Multimedia lovers can save money

Oddly enough, but for those who like to watch movies on a monitor screen and surf the Internet, purchasing a device with a TN+film matrix is ​​quite enough. An inexpensive gadget with an improved screen can easily replace a small TV. The problem can only appear in dark dynamic scenes, where instead of a black background the viewer will have to observe a gray cloud. If this is critical, you need to look towards VA matrices. Yes, the price is higher, but the problem with color rendering will be solved. In addition, the buyer will receive very high contrast and large viewing angles. Don't forget about the physical resolution of the matrix - the higher it is, the better the picture.

Office option

It would seem that the universal type of TN+film monitor matrix would be perfect for working with text. But, as practice shows, working with small print behind such a screen is extremely inconvenient. And if a monitor is purchased specifically for working with large volumes of text, then you should worry about your vision. The closest technology to TN at an affordable price is VA. Regardless of the manufacturer and screen size, such a device will allow you to sit at the computer for more than one hour without any problems.

When choosing a monitor for office work, attention should be paid to both the size and physical resolution of the matrix. The diagonal of the screen for working with text should not exceed the distance from the user’s eyes to the matrix. It is also recommended to select office monitors with an aspect ratio of 4:3, because in this ratio more readable information is placed on the screen.

New trend: for your loved one

Having studied all existing technologies of liquid crystal screens, before choosing the type of monitor matrix, a potential buyer should get acquainted with the information obtained through user surveys in the media.

1. The monitor is a durable purchase. That is, the next acquisition, with a high probability, will not be earlier than in 10 years.
2. In 99% of cases, the stated requirements for equipment do not coincide with operating conditions. That is, gaming battles are going on on the office monitor, but only news feeds are viewed on elite devices.
3. Multi-connection. For convenience, 25% of users in the world connect several monitors (2, 3, 4) to one computer, and the number of such owners is constantly growing. The convenience is that each connected device has a specific role - games, movies, office, etc.

The above information allows you to rethink your earlier knowledge. It is recommended to make a purchase based not on needs, but on desire and capabilities. Essentially, you should focus on the most expensive and high-quality device that the user can afford. You can't save money here.

In conclusion

Having found out which type of monitor matrix is ​​best for the user, what the letter markings on the device’s display mean and how it affects price and quality, you can begin to select the diagonal. However, many IT experts recommend paying attention to the resolution of the screen - how many dots per square inch it can display. Very often, the correct choice of the required resolution leads to the purchase of a monitor with a smaller diagonal, and, accordingly, to significant savings in money. The monitor manufacturer plays an important role - the matrix of its own production, the presence of a service center at the place of residence and a long warranty period hint to the future owner that he is purchasing a worthy device that will never let you down.

Instructions

In order to determine the type of matrix “by eye”, use some features that distinguish one type from another. Look at it not directly, but at an angle. The TN matrix is ​​characterized by the fact that when viewed from the side, there is an inversion of colors, a change in contrast, and so on.

Look at the device from the side - if you see a purple tint, most likely this is a monitor model with an IPS matrix type, in which this color is a characteristic feature of difference, while its absence often indicates an MVA\PVA matrix.

Direct your gaze at the monitor screen perpendicularly if you notice that at this viewing angle the color shades of the image disappear. Most likely, in this case you are looking at the MVA\PVA matrix.

Look perpendicular to the monitor screen. If you notice a drop in image contrast, distortion of colors and their shades (inversion), this may be a TN matrix.

To accurately determine the matrix type of a particular monitor, enter a query in a search engine using the name of the model you are interested in. Read reviews and technical specifications of the device, also visit the official website and view information there as well.

Please note that information about the monitor screen matrix can be included in the marking of its model, which is written either on the front side of the case or on one of the service stickers on the back. The combination of the letters TN, MVA\PVA, TFT and so on in the name may indicate that the corresponding type of matrix was used during assembly. Also, do not trust the information on the price tags, since sellers may also make mistakes in indicating the type of matrix. Always read the specifications on the official website or the packaging of the device.

Useful advice

When choosing a monitor, be guided by the features of its matrix.

• How can I find out what matrix I have?

The matrix is ​​the main and most expensive component of a laptop's LCD screen. Being a fairly fragile element, it can easily fail - for example, upon impact. Replacing the matrix is ​​not very difficult, so it can be done independently.

To repair a broken laptop, you will need a new matrix. There are three main options for searching: First of all, try to purchase it from one of the repair shops. But be prepared for the fact that they will refuse to sell you or sell it at an inflated price. It is not profitable for workshops to sell components, so the repairman would rather offer you to bring your laptop for repair than sell a spare part.

The second option is to look for a faulty laptop with the same matrix on the market. Sometimes the laptop itself may be badly damaged, but its screen may still serve. The disadvantage of this method is the inability to check the serviceability of the matrix on site. Finally, the third option is to try looking for a matrix in online stores. This method is the most profitable; the purchase will cost you approximately three to five thousand rubles, depending on the size and type of matrix. But it can take up to a month or more to deliver it by mail.

Before you start looking for a new matrix, make sure that the old one is really faulty. If the screen is broken, in this case there are no questions, the matrix must be changed. But if the screen does not light up, the problem may not be in the matrix. After turning on the laptop, shine a flashlight on the matrix. Take a closer look - if a weak image is visible on the screen, then the matrix is ​​in order, it’s just missing. The cause, as a rule, is a burnt-out inverter chip or the combustion of the backlight itself.

If it is the matrix that is faulty, to replace it, first use a screwdriver or an awl to remove the rubber plugs on which the screen rests when closed. There are screws under the plugs; carefully unscrew them. Now separate the halves of the screen cover by inserting something flat and thin into the gap between them - for example, a knife blade, a credit card, etc. The lid halves are secured with latches, so their separation may be accompanied by a rather loud crack.

Once you remove the plastic surround of the screen, you will see the screws holding the screen in place. Unscrew them, then, using a soft cloth, carefully remove the matrix. Disconnect the cables going to it. Now you can install a new matrix and assemble everything in reverse order.

We have examined in detail the markings of matrices, but sometimes situations arise when the required matrix model is not on sale and in this case you can select its analogue - fortunately, many models are completely compatible with each other. When choosing a matrix, you need to pay attention to its diagonal, resolution, connector and its location, thickness and fastenings - these are the characteristics that are extremely important for the correct selection of analogues.

The diagonal of the matrix is ​​indicated in its part number - these are the first three digits. For example, the matrix shown in the photo above has a diagonal of 15.6 inches: this is indicated by the numbers 156. The resolution of the matrix is ​​also sometimes reflected in its markings, but we recommend finding it out using our website or the documentation for your device: knowing the laptop model or matrix part number, you can easily find its resolution.

The matrix connector is used to connect it to the motherboard using a cable: modern models use LVDS connectors (there are models with 20, 30, 40 or 50 pins) or eDP (30 or 40-pin only), and the connector itself can be located on the right or left, depending on the laptop model. We recommend that you look at the location of the connector on the matrix yourself (for example, in the photo it is located on the right), and it is better to find out its type and number of contacts from the specification of the matrix by its part number - this information can be easily found on our website or on the Internet. It is also worth mentioning that LVDS connectors are usually designated only by numbers (for example, 40), and in the case of eDP connectors, their type is also indicated (for example, eDP 30).

With the advent of compact laptops and ultrabooks, in addition to standard matrices, manufacturers began to install thinner Slim or UltraSlim models. They can be distinguished from each other visually, but just in case, it is better to play it safe and look at the thickness of your matrix on our website or on the Internet.

Well, the last important parameter when choosing an analogue is the matrix mounts. As a rule, most matrices do not have any additional fasteners, but some models can be equipped with ears located from top to bottom, as in our first photo of the matrix, or from left to right.

To summarize, we can say that all these parameters are important for the correct choice of analogue, but they do not guarantee the normal operation of the matrix you have chosen: the fact is that each matrix has its own EDID - information about the parameters and capabilities, which is stored on a separate chip. In some cases, it is this information that prevents the screen from working normally in your laptop, therefore, for the correct operation of such a display, this matrix chip must be reprogrammed - this service is provided by many service centers.

Despite the fact that almost any matrix can be flashed, in practice it is much easier to select a problem-free matrix from the list of compatible models, not forgetting to compare all the critical parameters of the matrices discussed in this article: this will avoid unnecessary costs for flashing. That is why the next article in this series will be entirely devoted to matrix compatibility: we will clearly present a list of analogues in the form of tables for the most popular diagonals and resolutions, so that you do not have problems choosing the required model. Well, of course, you can always contact the specialists of our store: they will select a fully compatible matrix model, and you can order it in the “” section.
