Recently, I heard feedback from many friends in the circle that the screen goes black and does not display as soon as the phone is installed, and some are black or out of line after a few days; But when testing, the screen is completely no problem. In fact, most of these situations are caused by the non-standard installation process. Today, I will take you to understand the installation precautions.

1. The brackets show that the IC position is fragile and easily cracked when pressing, so be sure to install it carefully; (it is fragile and easily cracked, install it carefully to avoid damage)

2. Use as little glue as possible at the position of the cable during pressing, and install it carefully (remember: pull the cable flat, and apply as little glue as possible for pressing)

3. The iron backlight cable needs to be installed carefully when pressing (remember: the backlight cable is small and easy to break when pressed)

4. Dispensing glue on the periphery of a single piece and install it carefully (remember: use the edge of the pinhole cover to dispense glue evenly. Too many points are easy to corrode into the iron backlight, causing black and yellow blocks to display)

Reminder: Because many models currently have a full screen, too much glue can easily stick to the glass LCD. When the glue dries, it is easy to get out of the line when the phone is slightly pressed or collided with the screen!

At the same time, after the screen is installed, it is necessary to test the various performances of the screen, including screen wake-up test, screen black and white and gray three-color display test, touch test, earpiece test, and play short video to test whether the screen has random touches, screen jumps, etc., screen test After there is no problem, the installation work is truly completed.
