LCD显示器件在中国已有二十多年的发展历程,已经从最初的以数字显示为主转变为以点阵字符、图形显示为主。LCD显示设备以其低电压驱动、微小功耗、能够与CMOS电路和LSI直接匹配、具有极薄的扁平结构、可以在极亮的环境光下使用、工艺简单等等特点成为了极有发展前景的显示器件。LCD显示器件种类繁多、发展迅速,从种类到原理、从结构到效应、从使用方式到应用范围差异很大,从测试原理上来
LCD display device in China has more than 20 years of development history, has changed from the initial digital display mainly to dot-matrix characters, graphics-based. LCD display devices with its low voltage-driven, tiny power consumption, with CMOS circuits and LSI can be directly matched, with a very thin flat structure, can be used in extremely bright ambient light, the process is simple and so has become very promising Display device. LCD display a wide range of devices, the rapid development of species from the principle, from the structure to the effect, from the use of a wide range of applications, from the test principle
