The Huawei Mate 50 Pro is a premium smartphone released by Huawei, featuring a 6.74-inch OLED display, which offers a high-resolution viewing experience with vibrant colors and sharp contrast. It’s important to note that this phone does not have an LCD screen; instead, it utilizes an OLED screen. OLED screens are different from traditional LCDs in terms of technology and display performance. OLED (Organic Light Emitting Diode) panels offer better contrast ratios, richer colors, deeper blacks, and higher energy efficiency compared to LCD screens.
Given that the Huawei Mate 50 Pro uses an OLED screen and not an LCD, the following guide will focus on the replacement process for the OLED screen. If you are considering a replacement for your display, it is crucial to understand the steps and the care needed during the repair process.
1. Preparation: What You Need to Replace the OLED Screen
Replacing the OLED screen on the Huawei Mate 50 Pro requires specific tools and components. Here’s a comprehensive list of what you’ll need:
Tools Needed:
- Small screwdrivers (typically Pentalobe and Phillips screwdrivers)
- Plastic opening tools (to avoid damaging internal components)
- Suction cup tool (for lifting the back cover and screen)
- Tweezers (for handling delicate components)
- Heat gun or hairdryer (to soften the adhesive used for the screen and back cover)
- SIM card ejector (for removing the SIM tray)
- Replacement OLED screen (make sure it’s compatible with the Huawei Mate 50 Pro)
- Adhesive strips (for resealing the device once the screen is replaced)
- Anti-static wrist strap (optional, to protect sensitive components from static damage)
Replacement Parts:
- Replacement OLED screen: This should be compatible with your Huawei Mate 50 Pro model.
- Display adhesive: This will be needed for securely attaching the new screen.
2. Step-by-Step Process of Replacing the OLED Screen
The replacement process for the Huawei Mate 50 Pro’s OLED screen is delicate and involves several steps. Below is a detailed step-by-step guide for this procedure.
Step 1: Power Off the Device
Before starting any repair work, make sure your phone is powered off. This will reduce the risk of electrical short circuits and accidental damage to the device.
Step 2: Remove the Back Cover
The Huawei Mate 50 Pro features a glass back cover that is securely attached to the body of the phone. To access the internal components, you’ll need to remove the back cover.
- Heat the back cover: Use a heat gun or a hairdryer to warm up the back cover slightly. This softens the adhesive used to secure the back panel.
- Use a suction cup: Attach the suction cup to the back of the phone to create a gap between the cover and the phone body. Be gentle and avoid applying too much force.
- Insert a plastic opening tool: Once the gap is created, use a plastic opening tool to pry the back cover off. Work carefully around the edges to avoid cracking or damaging the glass.
- Disconnect the battery: After removing the back cover, you may need to disconnect the battery by removing the screws and using a plastic tool to lift the connector.
Step 3: Remove Internal Components and Screws
To reach the screen assembly, you’ll need to remove some internal parts.
- Remove screws: Use a Pentalobe screwdriver to remove screws securing the metal frame. Carefully keep track of the screws’ positions as they can be of different sizes.
- Disconnect components: Gently disconnect cables and components that may be in the way of the screen, such as the fingerprint scanner or the camera.
Step 4: Loosen the OLED Display from the Frame
The OLED screen is usually attached to the phone’s body with adhesive, so the next step is to carefully loosen the display.
- Use heat: Apply heat to the edges of the phone to soften the adhesive. Be sure to focus the heat on the edges and avoid overheating the display or internal parts.
- Lift the screen: Once the adhesive is soft, use a plastic opening tool to gently lift the OLED screen from the frame. Take care not to damage the screen or any internal components.
Step 5: Remove the Damaged OLED Screen
Once the OLED screen is lifted, carefully disconnect any remaining cables that attach the screen to the motherboard. You may need to detach the display’s flex cables that connect it to the device’s mainboard.
- Remove the screen: With all the cables disconnected, you should be able to remove the old, damaged OLED display from the phone.
Step 6: Prepare and Install the New OLED Screen
Now that you have removed the damaged screen, it’s time to install the replacement OLED display.
- Align the new OLED display: Ensure that the new OLED screen is aligned correctly with the phone’s body. Carefully reconnect all the necessary cables and connectors to the motherboard. This will ensure the screen works properly after installation.
- Test the display: Before sealing everything up, power on the phone and test the screen to ensure it works correctly. Check for any dead pixels, touch sensitivity issues, or display anomalies.
Step 7: Reassemble the Phone
Once you confirm that the new OLED screen is working perfectly, it’s time to reassemble your Huawei Mate 50 Pro.
- Reattach internal components: Reconnect any parts you may have removed or disconnected, such as the battery or camera.
- Screw the metal frame back in place: Replace all screws and secure the internal components with the metal frame.
- Seal the back cover: If you removed the back cover, apply new adhesive strips around the edges of the device and carefully press the back cover back into place. Ensure it is tightly sealed.
Step 8: Power On the Device and Final Checks
Once everything is reassembled, power on the device and verify that all functions are working correctly.
- Test the touch screen for responsiveness.
- Check the screen display for clarity, brightness, and any defects.
- Confirm that camera functionality is unaffected.
- Ensure the back cover is securely attached.
3. Final Considerations
- Warranty Impact: Replacing the screen yourself may void your phone’s warranty. It’s always a good idea to check your warranty terms or consult an authorized repair center if the device is under warranty.
- Cost and Expertise: Replacing an OLED screen is a delicate and intricate process. If you’re not experienced with phone repairs, it’s highly recommended to take the device to a professional repair service to avoid damaging other internal components.
- Replacement Quality: Ensure that the replacement screen is of high quality and compatible with your Huawei Mate 50 Pro model. Using substandard parts can lead to display issues or a short lifespan for the new screen.
By following this detailed guide, you can replace the OLED screen of your Huawei Mate 50 Pro, though it’s essential to approach the process with care and precision to avoid damaging the device. If unsure, it’s always better to consult or hire a professional technician to handle the replacement for you.
