Replacing the top panel on Xiaomi smartphones is one of the most sought-after repair procedures that owners face after falls, bumps or wear. The top panel (commonly referred to as a “display module” or “front assembly”) includes not only glass, but also a touch layer, and in most models – also itself. OLED/LCD-According to the statistics of the service centers, 40% The damage is caused by damage to this part of the device.
In this article, we will analyze the replacement process using popular models from the budget Redmi Note 12 to the flagship Xiaomi 14 Pro, specify the key differences between generations and give recommendations for the choice of spare parts, learn what tools you will need, how to avoid typical errors (for example, damage to plumes or detachment of the battery), and be able to assess whether to take up the repair yourself or better turn to professionals.
Important: the procedure requires accuracy and basic electronics skills, and if you've never disassembled a smartphone, work out on a broken device or watch a particular model's video demolition before you start.
Which Xiaomi models support replacing the top panel?
Not all Xiaomi smartphones can structurally replace the top panel without specialized equipment, and here are the key criteria by which you can determine the possibility of repair:
- 📱 Modular displays: Models with removable display module (e.g. Redmi Note) 10/11/12, POCO X3/X4). Here the panel is mounted on latches and double-sided tape, which makes it easier to replace.
- 🔧 Glue screen: Flagships (Xiaomi) 13/14, Mix 4) They often have a display glued all over the area, and they'll require a hair dryer, mediators, and adhesive experience.
- ⚠️ Non-collectible designs: Some ultra-budget models (e.g. Redmi) A1) may have a display soldered to the frame, making the replacement economically impractical.
Before buying a spare part, check compatibility by the exact model name (indicated on the box or in the settings along the way Settings). → The phone. → For example, the display for the Redmi Note 12 Pro is not suitable for the Redmi Note 12 Pro.+ due to differences in lighting.
| Xiaomi Series | Type of panel attachment | Difficulty of replacement (1-10) | Prices for spare parts (2026) |
|---|---|---|---|
| Redmi Note 10/11/12 | Latches + bilateral scotch | 4 | 3 500 — 7 000 ₽ |
| POCO X3/X4/X5 | Latches + glue around the perimeter | 5 | 4 000 — 8 500 ₽ |
| Xiaomi 12/13/14 | Full adhesion + metal-frame | 8 | 8 000 — 15 000 ₽ |
| Mix 4/5 | Clay. + slack-latch | 9 | 12 000 — 20 000 ₽ |
⚠️ Attention: On models with AMOLED-screens (for example, Xiaomi 13 Ultra) when replacing the panel may require a transfer of the chip OLED Driver IC Without this, the color calibration will be disrupted, and the screen can display artifacts.
Tools and materials: what you need to replace
The quality of the tools is responsible for 80% of the success of the repair, and here is the minimum set that most models will require:
- 🔨 Plastic mediators (thickness 0.1–0.3 mm) – for disconnecting the panel without scratches.
- 🔥 Thermophen or building hair dryer (300-500 W) - to soften the adhesive. Alternative: iOpener (heating package).
- 🔧 Screwdriver kit: cross-haired PH00, flat 1.5 mm, five-pointed Y00 (for some).
- 🧲 Magnetic mat or organizer for screws – so as not to lose small details.
- 🩹 Double-sided tape or glue B7000 — fixing.
- 📱 Suction cups (diameter 5-7 cm) - to raise the display after heating.
Critically, use only polycarbonate or nylon mediators, because metal blades will damage the plumes and antenna tracks under the display. IP-certification (for example, Xiaomi 13 Pro) after replacing the panel will need to restore tightness using the UV-glue and ultraviolet lamp.
If you are planning a replacement for the first time, we recommend buying a repair kit for a specific model (for example, "Kit for Xiaomi Redmi Note 12 Pro" on AliExpress). + spare screws and stickers.
Step-by-step: how to remove the old panel
The dismantling process varies depending on the model, but the overall sequence of actions is as follows:
- Turn off your smartphone and remove it. SIM-Memory card (if there is a slot).
- Heat the edge of the display with a hairdryer (temperature 60–80)°C) for 2-3 minutes, evenly running along the edge. Do not direct the air flow to the screen - this can damage the matrix!
- Put suction cups on the bottom edge of the panel (there are usually no plumes there). If the smartphone doesn't respond, repeat the heat.
- Carefully swipe the mediator along the side faces, dissolving the latches. On models with adhesive attachment (for example, Xiaomi 14) you will need to cut the glue with a knife or a special string.
- Open the panel as a book for 90.° And disconnect the display and sensor plumes (they are attached to the clip clip latches!
Attention to plumes: On models with a subscreen camera (for example, the Mix 4), the camera plume runs under the display - it is easy to damage if the panel is sloppy. Also be careful with the battery plume - its break can lead to a short circuit.
☑️ Preparation for panel removal
In some models (for example, POCO F5) There are additional screws underneath the display that lock the metal frame, and you have to unscrew them before the panel is completely removed, or you can tear the flexible cables.
What if the panel doesn't move?
Installation of a new panel: nuances and typical errors
Before installing a new panel, it is necessary to:
- 🧹 Clean the case of residues of old glue (use plastic scraper and isopropyl alcohol).
- 🔍 Check the plumes on the new panel - they should be whole, without clogs.
- 📏 Compare the old and new display connectors (sometimes even the original parts have differences in the location of the contacts).
Installation process:
- Connect the new panel plumes to the motherboard (start with the battery plume, then the display and sensor).
- Lay the panel in place, aligning along the side edges. On models with curved screens (for example, Xiaomi 13 Ultra), make sure that the glue does not fall on the flexible edges of the display.
- Close the panel and press it evenly (you can use a heavy book). For adhesive models, additionally warm the edges with a hair dryer (40-50).°C) for better adhesion.
Common errors that lead to re-repair:
- ❌ Panel skewing during installation → It leads to uneven gaps and poor tightness.
- ❌ Dust falling under the display → Black dots or divorces appear when turned on.
- ❌ Incorrect connection of plumes → The screen is not working or reacts to late touch.
💡
Before final assembly, turn on the phone with the panel connected, but not yet glued. Check the sensor (test in Settings). → Screen. → Touch test) and display of colors (no broken pixels).
How to check the performance after replacement
After assembly of the device, perform a comprehensive diagnosis:
- Display test: 🎨 Check the uniformity of the light (are there any dark spots in the corners). 🔴🟢🔵 Make sure all colors are displayed correctly (go to Settings). → Screen. → Colors and select the "Standard" mode").
- Sensor test: 👆 Swipe the screen in Touch Test mode (available in the Engineering menu or through apps like Touch Screen Test). 🖋️ Check the gestures (e.g. swipe upwards to return to the home screen).
Test of additional functions
- 📸 If the model has a subscreen camera (such as the Mix 4), take a selfie – the image should not be blurred.
- 🔊 Check the speaker (they can be attached to the display frame).
If after the replacement, artifacts appeared on the screen (strips, flickering), the reasons may be as follows:
- 🔌 Bad contact in the display plume connector - try reconnecting.
- 🔋 Incompatible firmware – some models require resetting after replacing the panel (via Settings) → Recovery and discharge).
- 🛠️ Refused spare parts - especially relevant for cheap non-original displays.
⚠️ Warning: On models with Always-On Display (such as Xiaomi 14), the light sensor calibration may be lost after the panel is changed. To fix this, restart the phone and wait for the automatic recalibration (it will take 5-10 minutes).
Where to buy spare parts: original vs analogues
The choice of a spare part directly affects the result of the repair.

| Copy (1:1) | Prices 30-50% lower than original, good quality | There may be problems with color calibration. | AliExpress (Xiaomi Parts Store), Beru, Yula |
| Aftermarket (universal) | The cheapest (from 2 000) ₽) | Low quality sensor, possible broken pixels | Avito, local repair shops |
When buying, pay attention to the following details:
- 📋 Part articulation – must match the original (for example, for Redmi Note) 12 Pro it could be. MDY-12-001).
- 📦 Set - the set must be bilateral scotch, screws and protective film.
