Xiaomi smartphone owners often wonder about the origin of components inside their device. This is especially true for screens, since it is the matrix that determines color quality, brightness and viewing angles. The same model body can use panels from different suppliers, which sometimes causes controversy among enthusiasts. You can find out who exactly made the display in several ways, ranging from simple visual inspection to deep analysis of system logs.
Chinese giant Xiaomi, like many other electronics manufacturers, does not advertise a specific matrix supplier for each batch of devices released. The specifications on the official website usually indicate only the type of matrix (for example, AMOLED or IPS) and its resolution. However, for those who want to verify the quality of the purchased gadget or plan to replace the component during repairs, there are proven methods of identification. The real supplier often becomes known only after a detailed study of the device.
There are three major brands whose matrices are most commonly found in Xiaomi, Redmi and POCO devices. These are Korean company Samsung Display, as well as Chinese manufacturers BOE and Tianma. Sometimes you can find panels from Huaxing (CSOT) or Visionox. Understanding whose matrix is installed in your smartphone helps to assess the potential durability of the screen and its technical characteristics, as different vendors may have different color calibration algorithms.
Analysis through CIT Engineering Menu
The most accessible way to get information about components is through a built-in diagnostic interface, with MIUI and HyperOS wrapping a custom CIT (Customer Integration Test) menu designed to test the health of all the phone modules, and this is where you can often find the display manufacturer, although this information is not available on all device models.
To enter the menu, you need to open the standard Phone app and enter a special code. Most often it is ##6484## or ##4636##. Once you enter the combination, the system will automatically switch you to test mode. You will need to find an item associated with the display, which can be called Version, Display, Screen or LCM Info.
⚠️ Note: The interface of the engineering menu may vary depending on the version MIUI. On some global firmware, items may be hidden or renamed. If the code doesn't work, try entering it through the Calculator app by switching it to currency calculator or converter mode.
The resulting code is usually alphanumeric. For example, a line can start with a prefix that indicates a vendor. Codes that start with SAMSUNG or contain SDC clearly indicate a Korean manufacturer. If you see labels like BOE, Tianma or Huaxing, you see products from the corresponding Chinese factories. Sometimes you need to decrypt the full model number through the Internet.
Using diagnostic applications
If the built-in tools don't provide a clear answer, third-party tools from Google Play come to the rescue. These apps read system logs and device properties, displaying information in a user-friendly way. One of the most popular and reliable tools is the Device Info HW app. It allows you to look deeper than standard Android settings.
After installing and running the program, go to the Display tab, the Manufacturer section or the driver description often indicates the company name, and you should also look at the Model or Panel field, for example, for the "Manufacturer" section. AMOLED-Samsung screens are often marked s6e3fc3 Or similar, where the first letters may indicate a series. IPS-Matrices may be less specific, but the brand is sometimes explicitly stated.
- 📱 Device Info HW — The most informative application showing detailed information about the sensor and matrix.
- 🔍 AIDA64 — powerful tool for collecting system data, including display ID display.
- 📊 CPU-Z — classic utility, which in the section "Device" can show a screen model.
It is worth noting that some applications may only show a driver name, not a commercial brand name, mdss_dsi_...) You can enter into a search engine along with the name of your smartphone model.Communities on forums such as 4PDA or XDA Developers often have already compiled code matching databases and manufacturers.
Checking through ADB and computer
For advanced users who are not afraid of the command line, the most accurate method is to use the Android Debug Bridge debugging bridge (ADB). This way you can access system configuration files that contain the exact details of the hardware you're connected to, USB-cable and included on the smartphone "Debugging by USB».
Once you connect your device to your PC and install the drivers, open the command line or terminal. Enter a command to list all the system properties and filter the result by display-related keywords. Often, the information you seek is hidden in properties that contain the words panel, lcd, or display.
adb shell getprop | grep -i panel
adb shell getprop | grep -i lcdIn output, you can see lines of the form [ro.boot.panel_supplier]: [boe] or [sys.lcd.id]: [samsung_aml_655]. This is the most reliable source of information, because the data is read directly from the bootloader or the kernel of the system. If the logs are tlite or innolux, then the device is using a matrix from these manufacturers.
Visual identification and disassembly
The most radical, but also the most accurate, method is to physically inspect the matrix plume, which is only suitable if you're planning a repair or have already disassembled the device, and the flexible plume of the display that connects to the motherboard is always marked, and it can be printed in black ink or engraved with a laser.
The labeling usually includes the manufacturer's logo or abbreviation. For example, the Samsung logo is difficult to confuse with others. Chinese manufacturers also put their logos: BOE, Tianma, Truly. In addition, the plume often shows the model number, which can be used to determine compatibility when searching for replacement parts.
It’s important to understand that even a smartphone model released at different times can have different screens. Xiaomi is known for its practice of rotating suppliers depending on the availability of components in the market. So two identical phones bought six months apart can have displays from different factories.
| Manufacturer | Typical symbols | Characteristics |
|---|---|---|
| Samsung Display | SDC, S6E3..., AMOLED | High brightness, saturated colors, deep black |
| BOE | BOE, M1/M2/M3 | Good color reproduction, often used in flagships |
| Tianma | Tianma, TM | Reliability is often found in the middle segment |
| Huaxing (CSOT) | CSOT, HX | High refresh rate, good viewing angles |
⚠️ Warning: Self-disassembly of the smartphone cancels the warranty. If the device is in warranty service, it is strongly recommended not to open the case to check the plume.
Comparison of characteristics of different vendors
The manufacturer's knowledge allows us to predict the behavior of the screen in different conditions. Samsung Matrixes are traditionally considered the benchmark for the use of the computer. AMOLED-It's power efficient and bright, but modern Chinese panels are very efficient. BOE Huaxing and almost equal to them in quality, especially in the top models Xiaomi.
Budget segments are more often used IPS-The difference between vendors can be more noticeable here, and panels from Tianma or Innolux can have slightly less accurate out-of-the-box calibration or wider bezels (frameless depends on the manufacturing technology). However, for everyday use, the difference may not be noticeable without directly comparing the two devices side by side.
When choosing a smartphone, many users are looking for information about the "lottery of matrices", indeed, everyone wants to get to the "lucky" matrix, but it is worth remembering that the software calibration that Xiaomi performs plays no less a role than the physical basis of the screen. MIUI Optimisation smooths the differences by making the picture pleasant regardless of the vendor.
Frequent identification issues and problems
Despite the many methods available, users often face difficulties, such as in some firmware (especially Chinese ones). ROM) information CIT-The menu can be encrypted or replaced with shared codes. ADB may not show the brand name, limited to technical ID.
Another problem is that there are fake screens after repairs. If you bought a used phone or changed the display in an unauthorized service, the manufacturer's verification becomes critical. The original matrix will have clear labeling and correct brightness values, while cheap copies often betray themselves as low resolution or lack of HDR support.
In conclusion, while Xiaomi hides direct information about the vendor in marketing materials, the technology makes it easy to get around this limitation. Whether it’s software analysis or a physical inspection, you can always find out what display technology is used in your device.
