Who made your Xiaomi screen? 5 ways to know the matrix manufacturer

Have you ever wondered why screens on the same Xiaomi models sometimes differ in color reproduction, brightness or even battery life, BOE, Tianma, Huaxing and others, even within the same model (for example, Redmi Note 11 Pro).+) There may be instances with different panels.

Knowing the exact screen manufacturer will help you compare quality before buying, diagnose problems (e.g., yellow tint in your screen). BOE In this article, we will discuss all the available methods, from simple (through service codes) to complex (disassembly of the device), and also tell you which matrixes are considered the best for different Xiaomi series.

Why Xiaomi is using screens from different manufacturers

Xiaomi doesn’t make the arrays itself, it buys them from third-party vendors, and it’s standard practice in the industry: even Apple and Samsung (despite their own screen production) sometimes use panels from competitors, the main reasons for this approach are:

• 📦 Supply diversification: single-produce dependency is risky – supply chain disruptions can occur (as was the case during the pandemic).
• 💰 Cost optimization. Matrixes from BOE Tianma is cheaper than Samsung Display, which allows you to keep the prices on smartphones low.
• 📊 Testing new technologies: Xiaomi experimenting with different types of screens (AMOLED, LTPO, 120 Hz, etc.), and for this you need different suppliers.

However, this approach has a downside: even in one batch of Xiaomi smartphones. 12T Pros can come across screens with different color temperature, contrast and response times. E4 are considered to be the brightness standards, and BOE — This is often criticized for being dirty white, so it’s important to know exactly what panel is installed in your device before you buy or repair it.

Method 1: Checking through the service menu (without root)

The fastest and safest method is to use hidden service codes, which works on most Xiaomi, Redmi and other models. POCO (including Redmi Note 10 Pro, Xiaomi 11T, POCO F4 You do not need root rights or special programs.

Instructions:

1. Open the Phone application (standard dialer).
2. Enter the code ##4636## or #284## (on some models).
3. In the menu that appears, select Hardware info (or Device Information).
4. Scroll down to the Display block, and there will be a Panel Manufacturer (or Producer) string.

If the code doesn’t work, try alternatives:

• 🔢 ##6484## - Display test (on some models displays the manufacturer).
• 🔢 ##36446337## — Advanced screen information (works on Xiaomi) 12/13 series).

Check the correctness of the code entry (without spaces)

Reboot your smartphone and try again.

• 🎨 Color gamma (sRGB, DCI-P3).

If this menu does not contain manufacturer data, then move to the next method, POCO X3 Pro) information can be hidden under encrypted codes - their decryption we will consider below.

💡

If the developer’s settings do not include “Display Information”, try updating it. MIUI Or use the DevCheck app from Google Play.

Method 3: Using Third-Party Applications

If standard methods don't work, specialized utilities will come to the rescue, and they will not only show the matrix manufacturer, but also provide additional data about the display: real refresh rate, bit depth of color, support. HDR etc.

How to use DevCheck:

1. Install the application and open it.
2. Go to the Hardware tab.
3. Find the Screen block, and there will be a Manufacturer string.

⚠️ Note: Some custom firmware (such as LineageOS or Pixel Experience) may show incorrect data, in which case only trust information from the service menu or physical disassembly.

Method 4: Decoding the markings on the screen plume

If you're ready to disassemble a smartphone (or it's already disassembled for repair), the most reliable way is to look at the labeling directly on the flexible plume of the matrix, which is suitable for 100% accurate identification of the manufacturer, since the data is taken from the factory sticker.

Where to look for markings:

• 🔧 On the back of the screen (if it is disconnected from the body).
• 📌 On the plume itself, it is usually a white or yellow sticker with inscriptions.
• 🖥️ On a metal screen (models with LCD).

Examples of markings and their decoding:

2. Heat the back cover with a hairdryer (60–70°C) to soften the glue.
3. Carefully tuck the lid with a plastic spatula (start at the corner near the charging connector).
4. Disconnect the battery plume, then the screen plume.

Method 5: Determination by serial number or IMEI

On some Xiaomi models, the matrix manufacturer is encoded in the serial number or IMEI. This method requires knowledge of specific labeling rules, but may work if other methods are not available.

How it works:

1. Find the serial number of the device in Settings → The phone. → General information.
2. Check the first 4-6 characters, which may indicate the batch and components.
3. Compare it to the database (see table below).

Examples of decoding for popular models:

⚠️ Note: This method does not give a 100% guarantee, since Xiaomi can change suppliers within a single batch. 2101119SG In 80% of cases, it has a Samsung screen, but in 20 cases, it is not% — BOE. For accuracy, combine this method with others.

💡

Serial number helps to identify the screen manufacturer for a limited list of models, and for most smartphones, this method is unreliable and requires rechecking.
