液晶显示具有微功耗、低电压驱动、平板形、可与CMOS LSI配合使用等优点,因此十余年来得到了迅速的发展。目前,电子手表、袖珍电子计算器等用液晶来进行显示已近乎是家喻户晓,而液晶字符、图形显示则有如异军突起,在广阔的领域向传统的显示器件——CRT(阴极射线管)提出了挑战。由于液晶显示具有的优点,用它来重现电视图象是令人鼓舞的。尽管在可以预见的将来,CRT在电视显示中仍将保持其盟主的地位,但在便携式、袖珍化方面却很难与液晶电
LCD has a micro-power, low-voltage driver, flat-shaped, with CMOS LSI with the advantages of use, so more than 10 years has been rapid development. At present, LCD displays such as electronic watches, pocket calculators and the like are almost universally known. LCD characters and graphic displays are like a meteoric rise and have posed a challenge to CRT (Cathode Ray Tube), a traditional display device in a wide field. . Due to the advantages of liquid crystal displays, it is encouraging to use it to reproduce television images. Although CRT will remain the dominant player in TV displays for the foreseeable future, it will be very difficult for LCDs to be portable or pocket-sized
