What are the Common Problems with LCD Displays? Quick Solutions at a Glance!

　　1. There are water drops on the screen

　　Reason: Water vapor in the air liquefies into small water droplets when it is cooled, and adheres to the surface of the glass. Over time, the water droplets gradually enter the LCD, resulting in water streaks, water mist, etc.

　　Solution: When using the LCD in a low room temperature environment, it is best to adjust the LCD temperature to 20-25 degrees, while keeping the indoor humidity no more than 60%, and keeping a certain distance between the screen and items to avoid condensation.

　　2. Uneven screen brightness

　　Reason: The problem of uneven brightness of the LCD screen is mainly caused by the uneven emission of the backlight tube. There are many reasons why the backlight tube emits uneven light, such as aging of the lamp tube, loose lamp tube bracket, etc.

　　Solution: For the problem of lamp aging, you can try to replace the lamp or the entire lamp bracket. For the problem of loose lamp bracket, you can try to re-fix the lamp bracket. If you cannot solve it yourself, it is recommended to contact professional maintenance personnel to handle it.
