Often we hear from friends or even in practice we are faced with a broken display. This failure often happens with mobile phones, but today we'll talk about matrices for laptops. When we see a broken display, the first thing that comes to mind is the question: how much does a replacement cost, how and where to find the necessary spare part?

The first step is to determine which matrix is ​​in our device. To find out the display model, you need to use such a wonderful program as EVEREST or AIDA. The program is very easy to use and with its help you will be able to view the laptop configuration. Unfortunately, this option is not suitable for everyone, or rather, it is suitable only for those who show at least part of the image. Another way to help determine the characteristics of the matrix is ​​to remove the matrix, that is, disassemble the laptop. Only the front trim frame needs to be removed. It is worth being careful with the panel, it is made of glass and can break or crack. It is worth remembering about elementary security measures, do not forget to turn off the mains power and disconnect the laptop battery when installing the matrix. These steps will help you avoid breaking the chips. Matrix microcircuits can fail due to breakdown by static electricity, so all manipulations related to mounting and dismantling the matrix should be carried out with antistatic gloves. Since the matrix surface is easily damaged, be careful not to scratch it during installation. If any liquid has got on the matrix, or it is dirty, then the contamination should be removed immediately. Be aware that prolonged contact with water may cause surface discoloration or staining. Make sure to properly install the flat cable into the matrix interface connector, it should not be rotated or tilted.

Having removed the matrix, we will see several stickers on the reverse side. Now, depending on the diagonal of your laptop, you need to find the right sticker.
If the screen diagonal is 10.1 inches, the sticker should have numbers 101, if the screen diagonal is 15.6 inches, then the sticker should have numbers and so on. But before the numbers indicating the diagonal of the display, there are always letters, this is a short designation of the matrix manufacturer, for example, LP101WSA (TL) (B1) means that this display was manufactured by LG Philips. There are not so many manufacturers of matrices on the world market. It should be noted that matrices for laptops are not faked, this is a multibillion-dollar production, so it’s simply impossible to make a spare part on the knee somewhere in the basement. To make the selection of a matrix more convenient and quick, we bring to your attention a table that shows the most famous manufacturers of matrices and their short designation.

Unfortunately, a well-known brand does not give a 100% guarantee that the matrix will be of high quality and will please the eye no worse than the promoted brand.

Naturally, it will be difficult for a non-professional to choose a matrix, and we strongly recommend that you seek help from service center to avoid misunderstandings. Our employees tried to make life easier for our customers, and now on the website on the product page you can find new section with the title "Helpful Tips". By opening the Helpful Hints tab, you will find specific information related to this product. This section provides tips for use, compatibility, and installation of spare parts.

ALL SPARE PARTS wants your laptops to always remain unharmed, but if trouble has already happened, then we will try to provide you with all the necessary spare parts. Good luck with choosing a matrix and its manufacturer!

A matrix for a laptop (tablet) is a fundamental element of the screen (information output device). The service life is quite long - about 5 years, but the matrix is ​​​​a very fragile component and often fails. The main causes of breakage are frequent carrying, shaking, shock, mechanical impact on the case, or the most common is closing the laptop lid with a foreign object (pen, pencil, mouse, etc.).

Matrices for laptops (tablets) have many differences in characteristics: surface type (matte or glossy), brightness, contrast, number of colors, response time, viewing angles, graininess. But to replace the matrix in a particular laptop (tablet), a completely different indicator needs to match.

Exist 5 main parameters when choosing a matrix for a laptop:

1. Matrix diagonal.
2. Illumination type - CCFL (tube) and LED (light-emitting diode).
3. Screen resolution in pixels (1024*600, 1280*720, 1366*768, etc.)
4. The connector to which the cable is connected, connecting motherboard with matrix decoder (30-pin or 40-pin)
5. Mounts for installing the matrix in a laptop (may not be available).

Matrices of the same diagonal, even from different manufacturers, are usually interchangeable with each other (for example, a matrix from AU Optronics can be replaced by Samsung), but there are limitations that arise when choosing them. For the matrix to fit specific model laptop, you need to make sure that all 5 of the above parameters are exactly the same!

As for manufacturers, it is worth noting the most common:

AU Optronics- short designation "B" e.g. B101AW03, B156XW02, B173RW01

Chi Mei- short designation "N" for example N101L06-L02 Rev.C2, N156B6-L06 Rev.C1,

Chunghwa- short designation "CLAA" e.g. CLAA101NB03A, CLAA154WA05 V.1, CLAA156WB11

LG Philips short designation "LP" e.g. LP101WSA (TL)(B1), LP156WH2 (TL)(Q1), LP173WD1 (TL)(A1),

Samsung short designation "LTN" e.g. LTN101NT02-101, LTN156AT02, LTN173KT01

Toshiba Matsushita short designation "LTD" e.g. LTD121EXVV, LTD133EWMZ, LTD133EE10000

HannStar- short designation "HSD" for example HSD089IFW1-A00, HSD101PFW2,

Hyundai-BOEhydis abbreviation "HT" e.g. HT15X34-110

Innolux abbreviation "BT" e.g. BT101IW03 V1, BT140GW01 V.2, BT156GW01 V.1

Also worth mentioning is the A Grade ISO 13406-2 quality standard. This is an international, officially recognized, standard by which liquid crystal displays are made. In accordance with it, for every million working pixels in the matrix, only 0.0002% of broken ones are acceptable. In other words, a matrix with a diagonal of 15.6 '' will not have more than 2 dead pixels.

When buying a matrix, be careful, in pursuit of a favorable price tag, you may stumble upon rejection from the factory. Such matrices are usually purchased from the factory in bulk, at a fabulously low price and do not meet quality standards. The risk of buying a matrix, on the image of which there will be from 5 to 100 dead pixels, is incredibly high.

The best option would be to buy from a large company that works directly with manufacturers, such as TopON. From such a company you will buy a high quality replacement, without defects and at an affordable price.

It is better to entrust the replacement of the matrix to a specialist, since this requires appropriate qualifications and experience.
If you want to replace the matrix yourself, then first find the appropriate instructions on the Internet, which will describe in detail how to remove the matrix from your laptop model. And be careful - all matrices are very fragile.

How to choose the right matrix for a laptop?

Attention! Some laptop models have matrices with different types screen backlight, resolution and even the diagonal of the matrix. For example, Dell laptop The M1330 is available with CCFL (tube) or LED (light-emitting diode) illumination. The Compaq R3000 is available in two different screen sizes: 15″ or 15.4″. Macbook Pro 15″ can have different matrix resolutions and they are not interchangeable.
You must make sure that the matrix you have chosen in our store is suitable for you in terms of size, resolution and backlight.

As a rule, manufacturers do not share matrix compatibility information among themselves, 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 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 plant.

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

Now you can use the search on the partsdirect .ru website or call 495-223-23-05 for information about the availability of the desired matrix or its interchangeable counterpart. In our store there is a huge range of matrices, so choose and buy the right matrix in Parts direct will not be difficult.

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

Instruction

In order to determine the type of matrix "by eye", use some of the features that distinguish one type from another among them. 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 a color inversion, a change in contrast, and so on.

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

Direct a perpendicular look at the monitor screen if you notice that the color shades of the image disappear at this viewing angle. 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 types of matrix of a particular monitor, enter a query in a search engine by the name of the model you are interested in. Read reviews and technical specifications devices, also visit the official website and view the information there as well.

Please note that information about the monitor's screen matrix can be found 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 can also make mistakes in indicating the type of matrix. Always read the specifications on the official website or the packaging from the device.

Useful advice

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

The matrix is ​​the main and most expensive component of the laptop LCD screen. Being a rather 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 need a new matrix. There are three main search options: first of all, try to purchase it in one of the repair shops. But be prepared for the fact that you will be denied a sale or sold at an inflated price. It is unprofitable for workshops to sell components, so the master will rather offer you to bring a 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 can be badly damaged, but its screen can still be used. The disadvantage of the method is the inability to check the health of the matrix on the spot. Finally, the third option is to try looking for a matrix in online stores. This method the most profitable, the purchase will cost you about three to five thousand rubles, depending on the size and type of matrix. But its delivery by mail can take up to a month or more.

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 glow, 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 is simply missing. The cause, as a rule, is a burned-out inverter chip or the combustion of the backlight itself.

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

Removing the plastic screen bezel reveals the screws holding the screen in place. Unscrew them, then, placing 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.
