Ever wondered whose technology is behind your Xiaomiβs bright screen?The display manufacturer directly affects picture quality, screen life, and even the cost of repairs when damaged. In this article, weβll look at how to determine exactly whose panel is installed in your device β whether itβs the flagship Xiaomi 14 Ultra or the budget Redmi Note 12.
Hidden information about the display manufacturer can come in handy in a few cases: when choosing a new smartphone (to compare screens of different models), before buying replacement parts or just out of curiosity, OLED-Samsung panels are considered the benchmark among screens for smartphones, while LCD from BOE But how do you know what's in your machine? Next, detailed instructions with step-by-step screenshots and technical code decoding.
Why it is important to know the display manufacturer Xiaomi
The screen is not just the face of a smartphone, but one of the most expensive components, and the quality of the screen depends on:
- π¨ Color and contrast - Samsung panels AMOLED traditionally lead in saturation of black (depth up to 0.0005 nits), while BOE OLED They may have a greenish tint when viewed from an angle.
- π Energy consumption - displays LTPO (Xiaomi 13 Pro automatically adjusts the refresh rate, saving up to 20% of battery life.
- π οΈ Repair cost β Samsungβs original panel for the Mi 11 Ultra can cost 2-3 times more than its counterpart from Tianma.
- β³ Lifetime is cheap. OLED-panels lose brightness faster (degradation up to 30% in 2 years vs 10% for premium screens).
Also, knowing the manufacturer will help avoid cheating when buying a used device, for example, if a seller claims that the POCO F5 is a Samsung E4 AMOLED, which is actually a BOE with the worst color reproduction, the difference in price can be used as an argument for bargaining.
β οΈ Note: Some Xiaomi models (e.g. Redmi Note 10 Pro) have displays from different manufacturers even within the same batch, called a βlottery displayβ β two identical smartphones can have screens with different characteristics.
Method 1: Through the engineering menu (codes and hidden settings)
The most reliable method is to use service codes or a hidden engineering menu, which works on most Xiaomi, Redmi and POCO devices (except the newest models with blocked access).
Instructions:
- Open the Phone app and type the combination: ##4636## Some firmware (e.g. MIUI Global) may run an alternative code: ##36446337###
- In the menu that opens, select Hardware info (or Device Information).
- Scroll down to the Display section, and here will be the Panel Manufacturer (or Producer) bar.
Possible values and their decoding:
| Manufacturer's code | Name of company | Type of display | Examples of Xiaomi models |
|---|---|---|---|
| SDC | Samsung Display | AMOLED, Dynamic AMOLED 2X | Xiaomi 13 Ultra, Mi 11 |
| BOE | BOE Technology | OLED, LCD (IPS) | Redmi Note 12 Pro+, POCO X5 Pro |
| TM or TMA | Tianma | OLED, LCD | Redmi 10, POCO M4 Pro |
| CSOT | China Star Optoelectronics (TCL) | OLED, LCD | Redmi Note 11, Xiaomi 12 Lite |
| LGD | LG Display | OLED (POLED) | Xiaomi Mi 10 (early batch) |
If the code is missing or the menu is not opened, try an alternative way through ADB (described below).On some devices (e.g. Xiaomi 14 with HyperOS), the engineering menu may be blocked - in this case, use methods 3-5.
Method 2: Through ADB-Teams (for advanced users)
If the engineering menu is not available, you can get information about the display through Android Debug Bridge (ADB), which requires connecting the smartphone to the computer, but gives the most accurate data.
Step-by-step:
Enable USB debugging in Settings β About Phone β MIUI version (click 7 times)
Install ADB drivers on PC (download from [developer.android.com](https://developer.android.com)
Connect your smartphone to your computer and confirm debugging
Download the ADB platform tools (or use MiFlash)
-->
After preparation, perform in the command line (cmd or Terminal):
adb shell dumpsys displayIn the conclusion, find the block HDR_CAPABILITIES Or DisplayDeviceInfo. Look for lines like this:
mPanelName=BOE NT37801 AMOLED FHD+Here BOE is the manufacturer, NT37801 is the panel model, AMOLED FHD+ is the type and resolution.
β οΈ Note: On HyperOS devices (e.g. Xiaomi) 14) The dumpsys display command can return incomplete data, in which case use an alternative command: adb shell cat. /sys/class/drm/card0/card0-LVDS-1/edid | hexdump transcription EDID-The code will require additional knowledge or an online decoder.
π‘
If ADB does not recognize the device, try reinstalling the drivers manually through Device Manager (select "Update Driver" β "Search on this computer" β specify the folder with the platform-tools).
Method 3: Through Diagnostic Applications
If you don't want to mess with codes or ADBs, you can use specialized applications that automatically read data from sensors and system files, displaying information in a convenient way.
Top.-3 check-in:
- π± CPU-Z β In the Device section, there is a Display item with the manufacturer and panel model.
- π AIDA64 β More detailed information in the Display section β Panel. Even shows factory color profile settings.
- π οΈ Phone INFO β Samsungβ β Despite the name, it works on Xiaomi. Shows Panel Manufacturer in the Hardware section.
Example of display in CPU-Z:
Note: Some applications (such as AIDA64) may show incomplete data on custom firmware or HyperOS devices. In this case, try a combination of several utilities.
What if the app doesnβt show the manufacturer?
Method 4: Visual inspection and screen tests
If the software methods didn't work, you can try to identify the manufacturer by the display features, which is less accurate, but sometimes helps to distinguish Samsung AMOLED from BOE OLED.
Test 1: Checking the color black
- π Open a completely black image (for example, through Google Photos or a special Screen Test app).
- ποΈ Look at the screen from an angle of 45.Β°. If the black color stays evenly black, it's probably Samsung β BOE or Tianma.
Test 2: Gradients and lanes
- π¨ Use a gradient test (e.g. in the Display Tester app). BOE often have a noticeable "strip" with smooth transitions of colors.
- π Look at the white background: Tianma displays may show a slight yellowish tint.
Test 3: Frequency of flickering (PWM)
- π‘ Turn on the front camera and point it at the white background screen. If you see flickering (especially at low brightness) BOE or CSOT PWM-controlled.
- π For accurate measurement, use the application PWM Test (available on XDA Frequency above 480 Hz is a sign of Samsung or LG.
Visual tests don't give 100% guarantee, but they help confirm data obtained in other ways, for example, if the engineering menu showed BOE, and the black test showed a greenish hue, this is an indirect confirmation.
Method 5: Based on the smartphone model and database
If your device is new or you are just planning to buy, you can find out in advance which display is used in a particular model.
- Official specifications β on Xiaomiβs website or in presentation materials sometimes indicate the type of panel (for example, β6.73β AMOLED from Samsungβ for Xiaomi 13 Pro).
- Disassembly and Reviews β Channels like JerryRigEverything or GSMArena often test displays and indicate their origin. For example, a Redmi K60 Pro review may mention that a BOE Q9+ panel is used.
- Repair center databases β sites like iFixit or Aliexpress (parts section) contain information about compatible screens. A search on a smartphone model + "LCD assembly" often gives the manufacturer a look.
Example of search queries for POCO F5:
POCO F5 original display panel supplier site:aliexpress.comResults can vary by batch, for example, the Redmi Note 12 Pro+ was first completed with the Samsung E4 AMOLED, and later switched to BOE.
| Xiaomi model | Manufacturer of the display (by default) | Type of panel | Features |
|---|---|---|---|
| Xiaomi 14 Ultra | Samsung Display | Dynamic AMOLED 2X, LTPO | Dolby Vision support, brightness up to 3000 nits |
| Redmi Note 12 Pro+ | BOE (early batch - Samsung) | AMOLED, 120Hz | Flickering at low brightness (PWM 480 Hz) |
| POCO X5 Pro | BOE or CSOT | AMOLED, 90 Hz. | Greenish tint when viewed from an angle |
| Xiaomi 12T Pro | BOE | AMOLED, 120Hz | It uses the same panel as the Realme GT Neo 3. |
π‘
Even within the same model, the display maker may differ, such as the Xiaomi 11T Pro came with screens from Samsung (SDC) and BOE β they are almost indistinguishable on the surface, but the color difference is noticeable when you compare them directly.
Method 6: Contact a service center or seller
If all previous methods have failed (for example, on a device with a locked engineering menu or custom firmware), there are two options:
- π Xiaomi official service β when you contact the warranty or for diagnostics, you can ask for information about components. In some countries (for example, in the EU), this is mandatory under the law on the right to repair.
- π¬ Store where you bought the device β if the smartphone is recently purchased, the seller can clarify the data from the supplier (especially important for offline networks like Svyaznoy or M.Video).
When contacting, please specify that you need information to:
- π§ Original parts selection (if you are planning a repair).
- π Comparison of characteristics (e.g., when choosing between two models).
- π‘οΈ Authentication checks (if there is a suspicion that the screen has been replaced by a non-original screen).
Important: Service centers donβt always meet the requirements for disclosure of this information, especially if the device is not guaranteed. The alternative is to contact independent workshops that specialize in Xiaomi and have access to spare parts databases.
