Description
Technical field
The present invention relates to technical field of liquid crystal display, relate to a kind of manufacture method of LCD display series products specifically.
Background technology
LCD is a kind of display device of planar ultra-thin of excellent performance, and its cardinal principle produces point, line, surface with galvanism liquid crystal molecule to coordinate back fluorescent tube to be formed picture.Comparatively traditional monitor (CRT) has excellent display effect.
Traditional CRT escope must by electron gun divergent bundle to screen, thus the pipe of kinescope just can not be too short, also must add large volume when screen increases, TFT then changes molecular state by the electron plate on display screen, to reach display object, even if screen strengthens, horizontal area only need increase by it, and volume can not be increased considerably, and much lighter than CRT monitor, TFT is because power consumption is only for electroplax and drive IC simultaneously, and thus power consumption is less.
Traditional CRT Display is that to hit the Nonopaque type display of the brightness ratio liquid crystal that thus shows of fluorescent powder by electron gun far better, and in visible angle, CRT is also better than TFT, and in display response speed, CRT and TFT is very nearly the same.
