When wiping the display screen panel, pay attention to the use of light force, and do not use hard objects to touch and scratch the panel, etc., and do not let any liquid enter the gap of the display boundary.

It is recommended that when cleaning, after the power supply and data lines are physically separated for 20 minutes, lay the display flat (to avoid liquid flowing into the gap due to gravity), and after the screen cloth is slightly moistened, pay attention to the boundary when wiping gently.

Never allow anything with moisture to get into the LCD monitor. Of course, once this happens, don’t panic.
