The life of crystal endoscope display device is very long, and the backlight module determines the life of LCD. At present, the backlight sources used in LCD are divided by technology, mainly including tungsten halogen lamp, light emitting diode (LED), organic electroluminescence (EL), cold cathode fluorescent lamp (CCFL), cathode emitting lamp (CLL) and metal halide lamp.

其中應(yīng)用較廣的是冷陰極熒光燈，主要是因?yàn)榇朔N背光源的性能、穩(wěn)定性及成本都較佳，目前幾乎所用的LCD內(nèi)窺鏡顯示器都是采用這種背光源。

Among them, cold cathode fluorescent lamps are widely used, mainly because this backlight has better performance, stability and cost. At present, almost all LCD endoscope displays use this backlight

平板型結(jié)構(gòu)：液晶顯示器件的基本結(jié)構(gòu)是由2片玻璃基板制成的薄形盒，這種結(jié)構(gòu)可以在有限的面積上容納大量的顯示內(nèi)容，顯示內(nèi)容的利用率較高。

Flat panel structure: the basic structure of liquid crystal display device is a thin box made of two glass substrates. This structure can accommodate a large amount of display content in a limited area, and the utilization rate of display content is high.

被動(dòng)型顯示：液晶顯示器件本身不能發(fā)光，它靠調(diào)制外界光達(dá)到顯示目的。因此無眩光，不刺激人眼，不會(huì)引起眼睛疲勞。對(duì)于黑暗中不能觀看的缺點(diǎn)，只要配上背光源，就可以克服。

Passive display: the liquid crystal display device itself cannot emit light. It achieves the display purpose by modulating the external light. Therefore, it has no glare, does not stimulate human eyes, and will not cause eye fatigue. The disadvantage of being unable to watch in the dark can be overcome as long as it is equipped with a backlight.

顯示信息量大：與CRT相比，液晶內(nèi)窺鏡顯示器件沒有蔭罩限制，因此像素點(diǎn)可以做得更小、更精細(xì)；與等離子顯示相比，液晶顯示器件像素點(diǎn)處不需要像等離子顯示那樣，像素點(diǎn)間要留有一定的隔離區(qū)。因此，液晶顯示在同樣大小的顯示窗面積內(nèi)，可以容納更多的像素，顯示更多的信息。

Large amount of display information: compared with CRT, the LCD endoscope display device has no shadow mask limitation, so the pixels can be made smaller and more fine; Compared with plasma display, liquid crystal display device does not need to leave a certain isolation area between pixels like plasma display. Therefore, the liquid crystal display can accommodate more pixels and display more information within the display window area of the same size.
