How long is the life of LCD?
The first floor you don't know what Dongdong, do not want to sell old!!!!, if you talk about electronic things you want to know what is called resistance. Capacitance. Diode, triode, integrated circuit, and so on. Their working principle. Then to the Baidu to brag!!!! if you are. Critics you another place to go to Baidu, because of the limited level of respondents
Not a good set, GB provides 50 thousand hours, but 50 thousand hours just said that has not qualified, not representative can not be used, and the traditional CRT, is long not, CRT are not produced, it is not being used, CRT display, CRT TV, liquid crystal life lies in his back part, mainly lamp, lamp aging is no way to avoid, but normal for you in 5 years is no problem.
First, the life of LCDLiquid crystal display power consumption, no radiation, for long-term use of computer workers, liquid crystal display is very suitable. Insufficient is, the life of LCD is quite short, and now the vast majority of the LCD on the market nominal service life is 2~3 hours (reportedly, ViewSonic LCD display can reach 5~6 hours). In other words, if 24 hours a day boot, you can only use 833~1250 days, less than 3.5 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. However, for IT products, the use of 5 years has been good, but also the replacement of the.The core components of liquid crystal display is two polarizers and a backlight module of liquid crystal layer and the main components of the backlight assembly is the two part of the backlight lamp and the light guide plate, determines the life is mainly the backlight lamp life, in a certain period of time after the deadline, the backlight lamp will appear aging, brightness decreases, when the tube the brightness decay to 50% when using time is defined as the lamp life.When the brightness of the LCD is reduced to a certain extent, the scanning line is not obvious. This is because the display automatically reduces the frequency of the tube.
