When cleaning the LCD display, do not wipe the screen surface with any alkaline solution or chemical solution. The smudges of the liquid crystal panel are roughly classified into two types, one is dust in the air stuck by the accumulated time, and the other is the fingerprint and oil stain left by the user inadvertently. If you do not pay attention to cleaning the LCD screen, it is easy to damage the LCD.
Wipe the LCD screen with a soft cloth or paper towel. Never use a soft cloth (such as a glasses cloth) or a paper towel to wipe the LCD screen. For a soft LCD screen, their surface is too rough, and it is easy to scratch the delicate LCD screen.
Clean the LCD screen with clean water. When cleaned with water, the liquid can easily drip into the inside of the LCD screen, which can cause a short circuit in the device and burn out expensive electronic equipment.
Clean the LCD screen with alcohol and other chemical solvents. Today's LCD screens are coated with a special coating on the screen. Once the display screen is wiped with alcohol, this special coating will dissolve and adversely affect the display.
