Recently, some customers reported that white spots appeared on the screen after installation, and then the product was damaged due to failure to take remedial measures in time. In response to this phenomenon, we have specially made video tutorials to address this problem and how to reduce it damage.
This is a video to tell you why some LCD will appear white dot during the installation and how to avoid it, we take the Huawei P20 lcd for example.
Since the connector is very small, we need to be very careful to connect the touch flex and lcd flex.
If you see the white dot, please take the LCD screen from the frame out immidiatey and reinstall it again. if over 3 minites the glue will be firmed and it will be hard to take it off and reinstall. If can not take the LCD screen will always has the white dot.
1. Put the glue on the frame quickly and evenly, must make sure there is no glue leaked out.
2. Insert the flex into the Lcd screen and check each side slowly and carefully, try to fix the flex softly.
3. Use rubber band to fix the Lcd screen and then connect the flex to the LCD tester .
4. The LCD backlight is very evenly so the installation is very successful.
Till now the installation is finished and if the white dot appeared , remember to take it off timely and reinstall again.
