You bought a used Xiaomi and you want to check if the previous owner has replaced the original screen with a cheap copy, or you just wonder what type of matrix is installed in your model β AMOLED, Super AMOLED classic IPS? The type of display depends on color reproduction, contrast, power consumption and even the cost of repair. In this article, we will discuss 5 reliable ways to find out the screen model on Xiaomi, Redmi or other devices. POCO β From standard settings to hidden engineering menus.
It is important to understand that the manufacturer rarely specifies the exact matrix model in the documentation. For example, in the specifications of the Xiaomi 13 Pro, it is written simply Β«AMOLEDΒ», But it may be that Samsung is there. E6 or BOE Q9+ β And these are fundamentally different screens in brightness and color gamut, and we're going to show you how to pull that information out even without disassembling your phone.
1. Check through phone settings (the easiest way)
Letβs start with the basic method that works on all Xiaomi smartphones under control MIUI. It wonβt give you an exact matrix model, but it will help you determine the type of display (AMOLED/IPS) and its key characteristics:
- Open the Settings. β The phone.
- Slip a few times on the line version MIUI, The message is βYou became a developer!Β».
- Go back to the main settings menu and select a new item for developers.
- Scroll down to the Equipment section and find the Display Type or Display info bar.
Here you will see one of the following inscriptions:
- πΉ AMOLED / Super AMOLED β if the screen is on organic LEDs (typical for flagships Xiaomi) 12/13/14, Redmi K50 Pro).
- πΉ IPS LCD β if the matrix on liquid crystals (occurring in budget models Redmi Note 11, POCO M5).
- πΉ OLED β Universal designation for LED screens (can mean Samsung) AMOLED, so BOE OLED).
β οΈ Note: Some firmware (e.g. custom) may not have a display type item.
If you are lucky, this menu displays the Display bar. ID Or Panel Name, write down the value of the matrix, and that's the exact matrix model that you can use to find the characteristics on the Internet, NT37800 β it IPS-screen from Novatek, and SDC_D6743 β AMOLED Samsung.
2.Use of engineering codes (##)
Hidden service menus are a storehouse of information about the hardware of a smartphone, and to get there, you just need to enter a special code in the Phone application. Here are the 3 most useful combinations for checking the display:
- π± ##4636## is a universal test menu. Go to the Phone Information tab and scroll to the Display block.
- π ##284## - Display test (not all models) - shows color profiles and possible artifacts.
- π οΈ ##6484## - menu MTK Engineer Mode (for MediaTek-based phones) Search Hardware Testing β Display.
In these menus, pay attention to the following parameters:
- πΉ Panel ID or LCD ID β Unique matrix identifier (e.g., Tianma) FT8720).
- πΉ Resolution β the actual screen resolution (sometimes different from the stated one, for example, 2400Γ1080 instead 2400Γ1080).
- πΉ Color Mode β Supported color profiles (sRGB, DCI-P3).
β οΈ Note: On some models (e.g. Xiaomi) 12T) If you don't have any engineering codes, you can turn them off. If you don't have any things going on after you enter the code, try using applications like this. MTK Engineering Mode (for MediaTek) or Qualcomm Service Menu (for Snapdragon).
If you see a Manufacturer line with a brand name (e.g. Samsung) on the menu, BOE, Tianma is a direct pointer to the matrix manufacturer, BOE Often supplies screens for Redmi Note, and Samsung Display β for flagship Xiaomi.

3. Display diagnostic applications
If the standard methods fail, third-party utilities will come to the rescue, and they will not only show the matrix model, but also test the screen for broken pixels, uneven backlights and other defects. TOP-3 tested applications:
| Annex | What shows | Link (Google Play) |
|---|---|---|
| CPU-Z | The display model in the Device section β Display (Collaboration Line) | Download |
| AIDA64 | Detailed information about the matrix, including manufacturer and resolution (Display) β LCD) | Download |
| Screen Test | Tests for broken pixels, gradients and color reproduction (does not show the model, but reveals defects) | Download |
V CPU-Z or AIDA64 Pay attention to the following lines:
- πΉ Panel / LCD β matrix model (e.g, SDC_D6743 Samsung AMOLED).
If the application displays a Unknown string instead of a matrix model, this may mean that the screen is replaced with a non-original one or the phoneβs firmware has been modified.
To verify the authenticity of the screen, use the broken pixel test in Screen Test:
- Launch the app and select the Color test.
- Turn on the red, green, blue and black screens in turn.
- Carefully examine the display for points, stripes or uneven backlight.

If you test on a black screen (Black) you see bright spots on the edges β this is a sign of backlighting. IPS-On the matrix. AMOLED The black color must be completely uniform (pixels are off).
4. Visual signs: how to distinguish AMOLED from IPS programmatically
If you don't have access to settings or apps, you can tell the type of display by the outside. Here are 4 key differences:
- π¦ Black: On AMOLED Black is completely deaf (pixels are off), on IPS β slurred.
- ποΈ Viewing angles: IPS does not change color when tilted, but AMOLED It may give a purple or green tint.
- βοΈ Brightness in the sun: AMOLED (Especially with the Sunlight Display mark, it is better read in bright light.
- π Energy consumption: On AMOLED The black wallpaper saves charge, IPS expense.
Do a simple test:
- Open any image with a black background (for example, wallpaper) AMOLED Black).
- Look at the screen from an angle of 45.Β°. If the black is still black, that is. AMOLED.
- Press the screen forcefully. If there are waves, it's IPS (on AMOLED There is no effect).
β οΈ Note: Some Xiaomi (e.g. Redmi Note 10 Pro) use Super AMOLED Samsung is visually indistinguishable from the standard AMOLED. The exact model of the matrix in this case can be found only through the engineering menu or disassembly.
Another sign is a flash on notifications. AMOLED-Xiaomi screens often use the Ambient Display feature, where notifications are displayed on the off screen with individual illuminated pixels. IPS You have to include all the lighting.
5. Phone disassembly: an extreme method for experienced
If all the previous methods failed, there's a physical test, and it's only for those who are willing to risk a warranty or have experience disassembling smartphones.
- π§ A set of plastic mediators (for a careful opening of the body).
- π₯ Hair dryer or thermo-air station (for softening glue).
- πΈ Loop or macro lens (to consider marking).
Algorithm of action:
- Turn off the phone and remove the back cover (heating the edges with a hairdryer).
- Disconnect the battery plume to avoid short circuit.
- Carefully place the screen around the perimeter with the mediator (start at the bottom edge).
- On the back of the display, look for a labeled sticker: πΉ Model: TM-XXX β screen. πΉ SDC-XXX β matrix from Samsung Display. πΉ BOE XXX β display BOE Technology.
On some Xiaomi models (such as the Mi 11 Ultra), the matrix marking can be hidden under a metal frame, in which case only specialized equipment from the service center will help.
β οΈ Warning: Disassembling the phone will void the warranty and may damage the plumes or matrix. If you are unsure of your skills, contact Xiaomi Service Center to ask for a "diagnose displayΒ».
After disassembly, be sure to check the tightness of the case - dust or moisture can disable not only the screen, but also other components.

Xiaomi Display Comparison: Which is Better?
Knowing the matrix model, you can compare its characteristics with other options. Below is a table with popular screens that are installed in Xiaomi, Redmi and other smartphones. POCO:
| Model matrix | Manufacturer | Type | Xiaomi models | Features |
|---|---|---|---|---|
| Samsung E4 | Samsung Display | AMOLED | Xiaomi 12 Pro, Redmi K50 Ultra | Brightness up to 1500 nits, support DCI-P3 |
| BOE Q9+ | BOE Technology | OLED | Xiaomi 13, POCO F5 Pro | Samsung's Budget Alternative E4, color-rendering |
| Tianma FT8720 | Tianma | IPS LCD | Redmi Note 11, POCO M4 Pro | Low power consumption but weak contrast |
| Samsung D6743 | Samsung Display | AMOLED | Xiaomi 11T Pro, Redmi K40 | High refresh rate (120 Hz), but less bright than the E4 |
If you are planning to replace the screen, consider:
- πΉ Original Matrixes from Samsung (E4, E5) More expensive, but better picture.
- πΉ Screens from BOE or Tianma is cheaper, but may have a yellow hue or flicker at low brightness.
- πΉ On Xiaomi IPS can be installed AMOLED-matrix, but you will need to firmware drivers.
Before buying a new screen, check its compatibility with Panel. ID (For example, in AliExpress, search for βXiaomi [model] + [Panel ID]Β»).

Even if you find the original matrix, it may not calibrate from the factory. After changing the screen, be sure to adjust the color profile in Settings. β Display. β Color mode.
Frequent problems with Xiaomi displays and their causes
Knowing the matrix model will help diagnose typical malfunctions, and here are the most common user complaints and their connection to the type of screen:
- π₯ Yellow color at low brightness - characteristic of BOE OLED-Matrixes (e.g. Xiaomi 12) are calibrated in the service center.
- π Rainbow stripes when scrolling - a defect IPS-Tianma, Innolux, more common after falls.
- β οΈ Dead pixels can appear on any matrix, but on the AMOLED more visible due to high contrast.
- π Fast battery discharge β if after changing the screen the phone began to discharge faster, probably installed poor quality OLED-high-power matrix.
If you notice one of these defects, try the following steps:
- Reset the display settings: Settings β Display. β Additionally. β Reset.
- Update the firmware: Sometimes color rendering problems are solved with patches from Xiaomi.
- Check the screen for broken pixels with Screen Test (see Section 3).
β οΈ Note: If artifacts appear when touching after the screen is replaced (such as "ghost" presses), this may mean that the new display module is incompatible with the sensor controller.
On the forums, the problem of screen flickering at low brightness at Xiaomi with a low brightness is often discussed. AMOLED-It's connected to technology. PWM (pulse-width modulation, which regulates brightness. If you're annoyed by that, try it:
- πΉ Increase the minimum brightness in the settings.
- πΉ Enable Reading Mode (Settings) β Display. β Reading mode).
- πΉ To use a dark topic, on AMOLED It reduces the strain on the eyes.
