LCD液晶显示屏自1968年问世以来,随着技术的不断完善和成熟,其应用日趋广泛。而自1985年世界第一台笔记本电脑诞生以来,LCD液晶显示屏就一直是笔记本电脑的标准显示设备。LCD通常有DSTN、TFT、HPA三种。 DSTN是由超扭曲向列型显示器(STN)发展而来的,由于DSTN采用双扫描技术,因而显示效果较STN有大幅度提高。笔记本电脑刚出现时主要是使用STN,其后是DSTN。STN和DSTN的反应时间较慢,一般为300ms左右。用户能感觉到拖尾(余辉),一般俗称为“伪彩”。TFT即薄膜场效应晶体管,属于有源矩阵液晶显示器(AM-LCD)中的一种,反应时间一般可以达到80ms左右。因其具有比其他两种显示器更高的对比度和更丰富的色彩,荧屏更新频
LCD display since the advent of 1968, with the continuous improvement of technology and maturity, its increasingly widespread use. Since the birth of the world’s first laptop in 1985, the LCD screen has been the standard display of notebook computers. LCD usually have DSTN, TFT, HPA three. DSTN was developed by the Super Twisted Nematic Display (STN). Since DSTN uses dual-scan technology, the display effect is greatly improved compared with STN. The laptop first appeared mostly using STN, followed by DSTN. The reaction time of STN and DSTN is slow, usually about 300ms. Users can feel the tail (afterglow), generally known as “false color.” TFT thin-film field-effect transistor, is an active matrix liquid crystal display (AM-LCD) in a reaction time can generally reach about 80ms. Because of its higher contrast and richer colors than the other two displays, the screen update frequency
