用于手机和笔记本电脑显示屏的技术是基于对液晶的使用——一项可以追溯到19世纪的发现。目前该技术已经应用于电视设备,引发了屏幕尺寸大小和图像质量的革命。液晶电视比传统的电视机更轻、画面更平,消耗的电能也更少。屏幕内部LED(发光二极管)灯泡最先进的屏幕使用发出红光、绿光和蓝光的二极管,这些颜色混合在一起就构成了强烈的白光,代替了传统的荧光灯管。 The technology used for cellphone and laptop screens is based on the use of liquid crystal - a discovery dating back to the 19th century. The technology has now been applied to television equipment, triggering a revolution in screen size and image quality. LCD TV lighter than traditional TV, more flat screen, less power consumption. The most advanced screen in the interior LED (light-emitting diode) bulb uses diodes that emit red, green and blue light that, when combined, form a strong white light that replaces traditional fluorescent tubes.
