4. Installation and Setup
Before installing the new display, it is crucial to perform a thorough inspection and test. The following steps outline the recommended pre-installation checks and general installation considerations.
4.1 Pre-Installation Checks
Every display part is tested with special instruments or main boards before shipping to ensure quality. However, it is essential to perform your own checks upon receipt.
Figure 4: Display Screen Pre-Installation Check Guide.
- Check Appearance of Front: Visually inspect the front of the display for any cracks, scratches, or physical damage.
- Check Stability of Frame: If the display comes with a frame, ensure it is stable and not bent or damaged.
- Check Situation of Flex Cables: Carefully examine the flex cables for any tears, creases, or damage.
- Test Touch: Connect the display to the mainboard (without fully installing) and test the touch functionality across the entire screen.
- Test Flex Cable: Ensure the flex cable connection is secure and the display powers on correctly.
- Test Dead Pixels/Dusty Lines: Check the display for any dead pixels, discoloration, or dusty lines that may indicate a defect.
Important: Do not remove any protective films or adhesive until you are completely satisfied with the display's functionality. Removing these may void the warranty.
4.2 General Installation Steps (Professional Installation Recommended)
While specific steps vary by watch model, the general process involves:
- Carefully open the watch casing.

- Remove the old display.

- Apply new adhesive (if not pre-applied to the new display) and carefully seat the new display into the watch frame.
- Reconnect any other components and close the watch casing.

Once the new LCD Display and Touch Screen Digitizer Panel is correctly installed, your Huawei Watch GT2 should function as normal. The display will show visuals, and the touch screen will respond to your input, allowing you to interact with your smartwatch's operating system and applications.
6. Maintenance
To ensure the longevity and optimal performance of your new display:
- Cleaning: Use a soft, lint-free cloth, slightly dampened with water or a screen cleaner, to gently wipe the display. Avoid harsh chemicals or abrasive materials.
