How long is the normal service life of LCD?
Service life of LCD displayCompared with the radiation that CRT displays can not eradicate, LCD has inherent advantages, and it basically has no radiation at all. LCDs are ideal for workers who use computers for a long time. Although the liquid crystal display power consumption and no radiation, but the LCD screen life is quite short, only about 5 years, and in use, the brightness will gradually decrease. Compared with the liquid crystal display, CRT display life is generally up to 10 years long, and that the effect will not be too big.The comparison of LCD and CRT is shown belowReference: http://digi.163 /04/0809/15/0TBT3JRC001618JK_6.html1. it is recommended to work under normal temperature / humidity conditions. High temperature / high humidity affects the life of liquid crystal displays.2., intense temperature fluctuations affect the performance of liquid crystal displays, especially low temperatures affecting brightness and response time.It is recommended to work in a smooth, clean environment where dust causes internal electrical circuits to fail.3., do not let the liquid splash into the display. If you need to clean, please turn off the power, spray the detergent on the soft cloth, and then wipe it gently.4. liquid crystal display is glass products, when moving, should avoid collision, vibration.5. liquid crystal display on the surface of multi-layer film, strictly prohibited with sharp instrument.6., forbid to disassemble the LCD at will, if the breakdown, must ask the professional personnel to maintain.7. fixed screen for a long time, will reduce brightness, image retention phenomenon increases, it is recommended to use screen saver.8. do not use for a long time, please turn off the power supply of the monitor and unplug the power plug.
The LCD panel itself does not emit light; it belongs to the backlight type display device. Behind the LCD screen, there is a backlight, LCD TV is to rely on the LCD panel on the panel "block" and "open" backlight lights, to restore the screen. It can be found that as soon as the LCD power is on, the backlight will start to work, even if the display is a full black picture, the backlight will remain in the same working state. Because the light transmittance of LCD panel is very low, the brightness of LCD TV should be reduced to the level of restore screen. The brightness of the backlight is at least 6000cd / m2. Backlight life is the life of LCD TVs, general LCD TV backlight life of more than 50 thousand hours. That is to say, if you use LCD TV on average 5 hours a day, the life of 50 thousand hours is equal to you can use the LCD TV for 27 years.
The liquid crystal display principle is: the voltage displacement crystal form the image, without moving image, crystal side does not move, the length of time to let the LCD manufacturers use normal, is not to let the display surface action too much, don't need LCD screen saver, you can turn off. In addition to this. You can only see how the generation of liquid appear daily.
