液晶显示是平面显示中发展最快、应用最广泛的新技术.从简单的电子钟表、计算器、数字仪表显示,到大信息量的O/A办公设备、计算机终端、声像通讯,她几乎深入到信息社会的各个领域.近几年,人们开发了新一代的电视机——液晶电视机(LCD-TV),具有高像质、高信息容量的有源矩阵特点,就其清晰度、对比度、灰度和视角等指标都可以与阴极射线管电视机(CRT)相媲美.它的工作电压只有几伏,而CRT约2—3万伏;它的能耗在毫瓦量级,而CRT却为50—80瓦;它的体积小、屏幕薄、重量轻,可放在衣袋或手提
LCD is the fastest growing and most widely used new technology in flat panel displays. From simple electronic clocks, calculators, digital meter displays, to large-volume O / A office equipment, computer terminals, and audio-visual communications, In recent years, people have developed a new generation of TV - LCD TV (LCD-TV), with high quality, high information capacity of the active matrix features, its clarity, Contrast, grayscale and viewing angles are comparable to cathode ray tube televisions (CRTs), which operate at voltages of only a few volts and CRTs of about 20,000 to 20,000 volts; and its energy consumption is on the order of milliwatts, CRT is 50-80 watts; its small size, thin screen, light weight, can be placed in a pocket or hand-held
