How to find out the matrix model of a laptop. How to find out the screen resolution on your phone How to find out your phone's display model
Xiaomi is a relatively young, but already mega-popular smartphone brand all over the world.
At the start, the company was engaged software, and not the production of equipment. Xiaomi initially created the MIUI shell and popularized it through Google Play. Over time, MIUI gained quite a lot of fans around the world, and Xiaomi began directly creating smartphones, tablets and other accessories.
To produce products, the company decided not to spend money on opening factories, of which there are already a dime a dozen in China. Xiaomi devices are essentially a collection of components from different factories and from different manufacturers.
Displays were no exception. They are produced in factories EBBG, Tianma and BOE. It would seem that they should all be identical, but in reality this is not at all the case. Displays made for the same model, but at different factories, will differ from each other in brightness, color rendering quality, shade saturation and other characteristics. For example, matrices from Tianma give off a purple tint, and the navigation buttons on these displays are only gray. Displays from the EBBG factory give a yellow tint. There is no information about the features of the BOE factory's products.
There are times when a client orders a display, installs it and, seeing the difference in color rendering, complains that it is a copy and not the original. Although in fact the whole point is in different factories, and not in the originality of the spare part. And neither the client nor the seller is to blame here.
When it comes time for repairs, it is quite difficult for customers to independently determine the factory where the display for a particular phone was made.
Therefore, we will tell you how easy it is to get the necessary data. All information about the device is in engineering menu.
Here are two pretty simple ways get into it:
- open the phone settings, go to the About device section and click on the Kernel item 5 times in a row. It will open before you engineering menu. Go to the Version Information section. The LCD line indicates the manufacturer (vendor). In our case, this is the Tianma factory.
- Enter one of the following combinations in your phone dialer application. With their help you will also be taken to the engineering menu, where information about the smartphone is indicated
- *#*#6484#*#*
- *#*#4636#*#*
- *#*#3646633#*#*
Once you have found out the manufacturer, be sure to include this information during checkout. This is the only way you can be sure that your new display will be the same as the original installed at the factory.
As you can see, everything is not as scary as it might seem at first glance. If you have any problems additional questions, please contact our contact center. We will be happy and quickly help you find a spare part.
When purchasing a smartphone, you need to check its authenticity. The best option is to go to the bootloader, however, if the key combination is unknown to you, you can use third party applications, which will allow you to determine which processor is installed, what resolution the display has and other parameters. And AIDA64 can be one of the options.
In addition, AIDA64 can be installed if you decide to study the insides of your device in more detail, since the application provides a lot of information. And, what’s most interesting, all the data in our case completely coincided with reality, which cannot be said about AnTuTu, which determined that the test One X had a 6-megapixel camera, although in reality the device has an 8-megapixel module.
The AIDA64 interface is simple, convenient and made in material design. Main screen is a list of categories, each of which will tell the user about certain parameters of the smartphone.
For example, if you go to the “System” section, the screen will display information about the smartphone model, manufacturer, serial number, the amount of RAM, its free part, and so on.
The “CPU” section shows the processor model, its architecture, cores, frequencies, technical process (in our case, 40 nm!). In turn, the “Display” tab will describe in more detail GPU, display resolution, its technology, screen dimensions, diagonal, very precise pixel density, OpenGL version and so on. The “Network” tab contains data about your network connections, including the network mask, gateway, and support information Wi-Fi technology Direct. By the way, the data mobile communications are also available and described in a fairly detailed form.
Of interest, we note the “Sensors” section, which shows information about all sensors, and also displays their operation in real time. This way you can verify how accurately and correctly your sensors are working. And the “Temperature” section will show how hot your smartphone is.
But this is still not all sections of AIDA64. If you want to study AIDA64 and your device in more detail, be sure to install this application. At least as an alternative to AnTutu and GPU-Z, this is a very good option, and it is constantly being updated and improved.
The Xiaomi brand supplies many smartphones to the world market, components for which can be supplied from various manufacturers. This also applies to screens that can be produced by EBBG, Tianma and BOE.
Interestingly, the same model can be equipped with displays from different brands. Their products, although slightly, differ in brightness, color rendering quality, shade saturation and other characteristics.
For example, matrices from Tianma gravitate towards purple shades, and their navigation buttons are predominantly gray. Products from EBBG are characterized by some yellowness, but buyers have no complaints about BOE.
How to find out what display is on Xiaomi
To do this, we need to use the capabilities of the engineering menu. Accessing its functions is very simple, just select one of the combinations below:
- *#*#6484#*#*;
- *#*#4636#*#*;
- *#*#3646633#*#*.
The second way is through the Settings menu. Find the “About phone” item and click on the “Kernel version” sub-item for 5 times.
Regardless of the selected option, the engineering menu will be displayed on the screen. At the bottom there is a line Device View.
Click on it and you will be taken to a new menu. The top line of the LCD contains information about screen resolution, supported video and display manufacturer.
So, you bought a smartphone or tablet, or maybe another device with a display, but it crashed and you don’t know what to do? There is no point in taking a broken device to a store; they won’t accept it for repairs because “there is mechanical damage", and with such a defect, unfortunately, devices are not accepted for warranty repair.
Of course, you may be offered paid repairs if you have an iPhone, Samsung device from a well-known manufacturer, and what if you bought it, for example, in China? Or do you have a gadget for which there are no spare parts anywhere? What to do in this case?
You need to look for the spare part where it is made!
Yes, yes, exactly in China. It is not necessary to go there; you can also look on Chinese sites, for example Aliexpress. The mail will arrive to us in about a month, maybe earlier. If you do not find the required touchscreen or display by the device model name, you need to look for the spare part by its marking. How to do it?
First of all, you need to find out the markings of your spare part, for example the marking of the touchscreen. To find out, you need to completely disassemble the device and its number will be on the cable. Yes, unfortunately, if you have a very rare device and there is no information on it, this is the only way out. It won't work any other way.
What the touchscreen markings look like:
.Knowing the markings of the touchscreen or display, finding it will not be difficult!
The touchscreen or display markings are applied directly to the cable. Using this number, finding the required spare part is usually easy. It may not always be original, but compatible ones are also suitable, especially when there are no alternatives.
Thus, knowing the marking of the spare part, you look for it on Chinese sites, since absolutely everything is there, and you will definitely find the necessary thing for your device
How to choose a touchscreen - touch glass for GPS navigator and car radio
The main types of touchscreen failure:
1. does not respond to clicks
2. crack on the touch glass
3. “oil stains” or otherwise “sticking” of the sensor
4. overheating or freezing of the touchscreen
5. tearing off the cable
Also, if you don’t know what is faulty - the display or the touchscreen, read here -
To choose the right touchscreen for a GPS navigator or car radio, you need to measure it correctly!!!
In our store on our website all sizes and part numbers are indicated, as well as possible compatibility with devices (width in mm, height in mm, cable length). And we take the photos ourselves, so they fully correspond to the product.
The main differences between touchscreens of the same standard size:
1. size - discrepancy between the width and height of touchscreens in millimeters (1-4mm)
2. location of the cable (usually also not critical, but convenient)
3. type of installation of the touchscreen cable to the navigator (soldered or inserted into the connector)
4. There may be a discrepancy in alignment (not critical, you just need to swap the contact tracks for touchscreens that are soldered)
The most important thing is to choose the size of the touchscreen, and you can assume that the size of the purchased touchscreen will be larger/smaller than the original one. This is due to the fact that, as a rule, it is always possible to insert a touchscreen either a little larger or a little smaller - everything can be seen directly from the disassembled device.
How to measure the touchscreen correctly:
1. You can measure the touchscreen correctly only by disassembling the navigator and seeing in front of you the display module on which the touchscreen is glued
2. The touchscreen should be measured from edge to edge using a metal ruler or caliper
3. The touchscreen always has the shape of a rectangle or square!!! with right angles! On some navigators, a decorative film of the front panel is glued over the touchscreen, do not measure it, but the touchscreen itself!!!
You can see how to disassemble the navigator in the section SERVICE or here:
You can also try to select the touch glass by the part number, which is indicated on the edge of the touchscreen (but not always). But this is rare, and you shouldn’t dwell on it.
It is better for the cable to be in the same location as on the original touchscreen. But if the cable even comes out in a different place or is too short, then you can always bend it, or, for example, build it up with an old cable, or re-solder the wiring.
Also, each of our touchscreens indicates possible compatibility - this is information collected from our customers, i.e. They purchased this touchscreen and it fit their navigator or car radio.
Now a few photos of how to measure a touchscreen and how not to do it!

We kindly ask you, if you purchased a touchscreen and replaced it on your navigator, please let us know which touchscreen was suitable for which navigator - this will be useful to everyone.
Also, if you have a desire, you can write a short article with a photo and we will be happy to post it on our website!!!
