Liquid Crystal Display (LCD) | 液晶显示屏

A screen for displaying text/graphics based on a technology called liquid crystal, where minute currents change the transparency by changing the polarization angle. The advantages of LCD screens are very small power consumption (can be easily battery driven) and low price of mass-produced units. The disadvantages are narrow viewing angle, slow response, invisibility in the dark unless the display is back lighted, and difficulties displaying true colours with colour LCD displays.

 

能在液态晶体上显示文字/图像的屏幕，通过微小的电流改变折射角度从而改变透明度。LCD屏幕的优点是非常小的能耗（可电池供电）和低价批量生产。缺点是观看角度小，反应慢，除了背光外在光线暗时能见度低，并且难以在彩色LCD显示上展示真实颜色。
