液晶显示正在向实用化迅速迈进。液晶显示的应用研究,是从1968年RCA发表动态散射式(简称DSM)液晶显示开始的,当时认为寿命是个问题,但1971年实验结果表明:DSM显示的寿命能达到一万小时以上,并试制了液晶手表(参看照片1)。之后世界上各个电子厂、手表厂分别发表、出售了液晶数字手表,迎来了液晶显示实用化的第一阶段。 然而,由于DSM显示的驱动电压高、对比度低等,而且,对小电池作电源的手表来说,耗电量大,也是不可忽视的问题。后来瑞士和美国一些公司发表了使用偏振片的新的场效应(简称FE)显示。在此前后,
LCD is rapidly moving towards practicality. The research on the application of liquid crystal displays began with the publication of the Dynamic Dispersion (DSM) Liquid Crystal Display (RCA) by RCA in 1968. At that time, life expectancy was considered as a problem. However, the experimental results in 1971 showed that the life span of DSM can reach over 10,000 hours, The LCD watch (see photo 1). After all the world’s electronics factory, watch factory were published, the sale of LCD digital watches, ushered in the first phase of practical LCD. However, due to the high driving voltage displayed by the DSM, low contrast, and the like, the power consumption of the watch for the small battery is also a problem that can not be ignored. Later, some companies in Switzerland and the United States published a new field effect (referred to as FE) display using a polarizer. Before and after this,
