How to know exactly the screen manufacturer on the smartphone Xiaomi: from Samsung to BOE

The screen of a smartphone is not just a display, but a key component that determines image quality, color reproduction and even battery life. Xiaomi, like other manufacturers, has screens supplied by different companies: Samsung, BOE, Tianma, Huaxing and others, even in one model (e.g. Redmi Note 12 Pro).+) Matrices from different brands can be found - and their characteristics will differ significantly.

Why does it matter? Because Samsung's arrays are traditionally considered the benchmark for color reproduction and brightness, whereas screens are the benchmark for color reproduction. BOE If you’re buying a smartphone from hand, planning a screen replacement, or just want to understand why your Xiaomi 13 Ultra displays colors differently than your friend’s, identifying the matrix manufacturer is the first step.

In this article, we'll look at 5 working methods to find out who made your device's screen, from hidden engineering codes to hardware analysis. MIUI" or questionable applications: only proven methods that work on models 2020-2026.

1. Check through the engineering menu (codes ##)

The fastest and most reliable way is to use hidden service codes, which work on most Xiaomi, Redmi and other smartphones. POCO (Except for some budget models with stripped-down firmware, you don't need root or special apps, just the phone keyboard.

Follow the following steps:

  1. Open the Phone app.
  2. Enter the combination: ##36446337## (this is the code for the display test).
  3. You'll see a menu with technical information on it. Look for lines like Display. ID, Panel Manufacturer or Vendor.
  4. Compare the value found with the manufacturers table below.

If the code doesn’t work, try alternatives:

  • πŸ”’ ##4636## β†’ Go to the tab "Phone Information" β†’ Find out about the Display section.
  • πŸ”’ ##284## (sensor test, sometimes displays matrix data).
  • πŸ”’ ##6484## (for some models) POCO).

πŸ’‘

If nothing happens after you enter the code, make sure you use a standard keyboard. MIUI, not third party (e.g. Gboard).

⚠️ Note: On some smartphones (e.g. Redmi A-series), the engineering menu may be blocked by the manufacturer.

2.Use of applications for screen analysis

If the service codes didn't work, or if you want to get more detailed information, specialized tools will come to the rescue, and they will not only show the manufacturer of the matrix, but also test it for broken pixels, uneven backlights and color deviations.

Top.-3 Proven applications for Xiaomi:

  • πŸ“± Screen Test (from Asus) - shows Panel Manufacturer in the "Info" section. Free, no ads.
  • πŸ“± Display Tester – Analyzes the type of matrix (AMOLED/IPS) And the manufacturer, there's flicker tests and color gamut tests.
  • πŸ“± AIDA64 β€” in the Display section β†’ Panel displays complete information, including screen model and resolution.

How to use (in the example of AIDA64):

  1. Install the app from Google Play.
  2. Open the Device section β†’ Display.
  3. Find Panel Manufacturer or Display ID.
  4. Check the data with the table from the previous section.
What if the app doesn’t show the manufacturer?
If AIDA64 or Screen Test is not available on the manufacturer, this may mean: 1. Your device uses a little-known matrix (for example, from Visionox). 2. MIUI modified (castomy or regional version). 3. the manufacturer hid the data at the software level (found at the same time in the company). POCO In this case, try the methods 3-5 from this article.

The advantage of this is visual diagnostics, for example, in Display Tester, you can run a test. PWM-flickering (characteristic of cheap matrices) BOE) Check the uniformity of the lighting, which is especially important for AMOLED-screen.

3. Visual signs: how to distinguish Samsung from the BOE programmatically

If you don't have the ability to use codes or apps, you can try to identify the matrix manufacturer by appearance, a method that is subjective but often works for popular Xiaomi models.

Key differences in matrices:

  • 🌈 Samsung: warmer and richer colors, deep black AMOLED), stripless.
  • ❄️ BOE: cold shade (blueish white), less clear boundaries between colors, possible illumination at the edges.
  • πŸ” Tianma/Huaxing: often occurs green tint at low brightness, less bright colors.

How to check:

  1. Open the Settings β†’ Display β†’ Color mode.
  2. Select the Standard Mode (without correction).
  3. Look at a white background (e.g. in a browser or notebook): If white appears yellow/cream β†’ It's probably Samsung. β†’ BOE. If there are green or purple spots on the gray background β†’ Tianma.

For a more accurate test, use color gradients:

  • Open this image to full screen: Test gradient.
  • On matrices. BOE Frequently visible bandings during smooth transitions.
  • Samsung. AMOLED The gradients will be flat, without breaks.

⚠️ Attention: Visual method doesn't always work! For example, Xiaomi 12 Pro may have a Samsung matrix E4 or BOE Q9+, but with the color setting MIUI They can be artificially "fitted" to a standard.

4. Analysis of the screen model through ADB (for advanced users)

If you are ready to dive a little into the technical details, you can find out the manufacturer of the matrix through the ADB (Android Debug Bridge: This method requires a computer, but it gives you 100% accurate results.

Instructions:

  1. Enable Developer Mode on Smartphone: Go to Settings β†’ About the phone. Press 7 times on the version. MIUI.

USB debugging

Connect your phone to your PC and open the command line (Windows) or terminal (Mac/Linux).

adb shell dumpsys display
mPanelManufacturer = [Here will be the title]


mPanelModel = [Matrix model]

Example of output for the Redmi Note 11 Pro+ 5G Samsung-screen:

mPanelManufacturer = samsung


mPanelModel = AM-S6E3XA1

If the command fails, try an alternative request:

adb shell getprop ro.boot.displaypanel

Install ADB-Drivers (Platform Tools)|Enable debugging on USB|Connect your phone to the original cable|Check the connection of the adb device team-->

⚠️ Note: On some smartphones (for example, POCO X3 Pro) output ADB It can be limited. In this case, use the app. MTK Engineering Mode (for MediaTek-based devices) or Qualcomm Service Mode (for Snapdragon).

5. Phone disassembly: Physical identification of the matrix

This is an extreme method that should only be used if:

  • πŸ”§ You are planning to replace the screen and are already disassembling the phone.
  • πŸ” None of the software methods worked.
  • πŸ“¦ You have experience with electronics (risk of damage to plumes!).

How to determine the manufacturer by labeling:

  1. Remove the back cover and battery (on models with removable batteries, for example, Redmi). 9A).
  2. Disconnect the screen plume from the motherboard.
  3. On the back of the matrix, look for a sticker or engraving with the code. Examples: Samsung: AMS643JK01, AMOLED SDC. BOE: NT36672A, BOE FHD+. Tianma: TM FT8719, NLT-1234.

Panelook

Important: On models with adhesive screen (for example, Xiaomi 13 or Xiaomi). POCO F4 GT) Disassembly without special equipment can damage the matrix or sensor.

πŸ’‘

Physical disassembly is the only way to know the matrix manufacturer on phones with locked engineering menus (e.g. global versions of Redmi). A1+).

Online services and databases: serial number check

If you know your smartphone’s exact model and serial number, you can try to find the matrix information in open databases, a method that is suitable for new devices (2022-2026), as older models may not be included in the catalogs.

Where to look:

  • 🌐 Panelook is the largest matrix database, and type in a phone model or screen code (e.g., a mobile phone, AM-S6E3XA1).
  • 🌐 GSMArena (website) – the β€œDisplay” section sometimes indicates the manufacturer (e.g., Xiaomi) 13T Pro).
  • 🌐 XDA Developers – the forum often discusses which matrices are used in specific batches (look for the topic of your model).

How to find out the serial number:

  • Go to Settings β†’ About the phone β†’ General information.
  • Find the serial number or IMEI.
  • Enter the number on IMEI.info – sometimes the report indicates information about the display.

Example of a search on Panelook:

  1. Go to the site and search for a phone model (e.g. Redmi Note 12 Pro Speed).
  2. In the results, look for the Display Panel section.
  3. Verify the data with your matrix (resolution, type, manufacturer).

⚠️ Attention: Online databases are not always relevant! A manufacturer can change matrix suppliers even within a single model. 12T In the first batches went with the screen Samsung, and later – with BOE.

Comparative table: which screens are better?

If you've identified a matrix manufacturer but you don't know how good it is, this chart will help you figure it out. We've compared the key features of screens from different brands with popular Xiaomi models.

FAQ: Frequent questions about Xiaomi screens

Can the screen be replaced? BOE on Samsung in the service center?
Technically yes, but there are nuances: the original matrix Samsung for Xiaomi are 1.5-2 times more expensive than BOE. Not all services are taking this replacement because of the differences in the plumes and firmware, POCO F3) after the matrix is replaced, calibration is required MI We recommend checking with official Xiaomi partners or in services with experience with Flash Tool. AMOLED-screen.
Why on my Xiaomi? 12T screen flickers at low brightness?
This is a characteristic problem of matrices. BOE s PWM-Pulse-width modulation. To reduce flickering: Set brightness above 30-40%. Enable Read mode in the display settings (reduces eye strain). Use a dark theme for the display settings. AMOLED If the problem is critical, consider replacing the screen with Samsung (but this does not guarantee the absence of a flash). PWM β€” Some Samsung matrices use it too).
How do I know if the screen is original after being replaced?
Check the following signs: πŸ” Build quality: the original screen fits tightly to the body, without gaps. πŸ“± The work of the sensor: on non-original matrices, touching the edges often β€œfloats. πŸ’‘ Backlight: Samsung's original screens have no stains or yellowness. πŸ”§ Diagnostics: enter the code ##36446337##, if the matrix data is missing, it is a fake. ADB (method 4) – on the original matrices it matches the data in the Xiaomi database.
Does the screen manufacturer affect battery life?
Yeah, and pretty significant: πŸ”‹ Samsung Matrixes AMOLED (particularly E4/E5) on 15–20% more energy efficient BOE. ⚑ Screens. BOE Often require more brightness for comfortable use, which reduces operating time. β˜€οΈ The sun is on the Tianma matrix. IPS They consume more energy because of the brightness of the backlight. If you want autonomy, you should prefer models with Samsung-confirmed screens (for example, Xiaomi). 13 Lite or Redmi K50 Ultra).
Can I improve the color on the screen? BOE?
Yes, by calibration in the settings. MIUI: Go to Settings. β†’ Display. β†’ Color mode. Select Saturated or Customized. Adjust sliders: Reduce the Cold (add warm tones). Increase saturation by 10–15%. Use apps like Screen Balance to fine-tune it. You can also set a color profile through the screen. ADB: adb shell settings put system display_color_mode 1 (where 1 β€” saturation, 0 β€” standard).
