Computer liquid crystal display
Introduction:
Computer liquid crystal display, abbreviated as LCD(LiquidCrystalDisplay), is an ultra-thin flat display device, which consists of a certain number of color or black and white pixels and is placed in front of a light source or a mirror. Liquid crystal displays are favored by engineers because of their low power consumption, and are suitable for electronic devices that use batteries. Its main principle is to use current to excite liquid crystal molecules to produce points, lines and surfaces, and cooperate with backlight to form a picture. Liquid crystal display (LCD) is widely used in industrial control, especially in the man-machine interface of some machines, the panel of complex control equipment and the display of medical instruments.
How to use:
1. Avoid burning in the screen.
Turning on the LCD for a long time mentioned above will shorten its life. So in order to avoid this situation,
2. Keep the humidity of the environment.
Don't let anything with moisture enter the LCD. If moisture has entered the LCD, the LCD must be placed in a warmer and drier place to evaporate the moisture and organic matter, and then turn on the power. The charged LCD due to moisture will lead to the corrosion of liquid crystal electrodes, which will cause permanent damage.
3. Avoid unnecessary vibration
LCD can be regarded as the most sensitive electrical equipment. LCD contains a lot of glass and sensitive electronic components, so the screen is very fragile. We should try our best to avoid strong impact and vibration, which can easily lead to the damage of LCD screen and CFL unit. Be careful not to put pressure on the LCD display surface, and the bad habit of pointing at the screen must be corrected.
4. Don't try to remove the LCD.
Generally, do not disassemble the LCD. Even after being turned off for a long time, the CFL converter in the background lighting assembly may still have a high voltage of about 1000V, which will cause serious personal injury. Therefore, do not attempt to disassemble or change the LCD screen to avoid high voltage. Unauthorized maintenance and changes will cause the display screen to temporarily or even permanently fail to work. If there is any fault, it is recommended to take it to a professional maintenance station for maintenance.
