在信息社会中,各种显示器的应用越来越广泛,成为传递信息的重要媒介。人们对显示器也有了更多的认识。在多种显示器中,包括历史最长、应用最广的阴极射线管(CRT);还有近年来迅速发展起来的各种平板显示器,如液晶(LC)、等离子体屏(PDP)、真空荧光(VFD)、电致发光(EL)和发光二极管(LED)。随着信息量的增大,人们每天都要接收并处理大量信息,其中有很大一部分是可见信息。这样,就要求显示器不仅能显示简单的文字符号,还应能够显示图象信息并有较大的容量。对于办公室自动化(OA)设备和信息处理
In the information society, a variety of monitors are used more and more widely, and become an important medium for transmitting information. People have more awareness of the monitor. Among the many types of displays are cathode ray tubes (CRTs) that have the longest history and are the most widely used, as well as various flat panel displays that have been rapidly developed in recent years such as liquid crystal (LC), plasma display panels (PDPs), vacuum fluorescent (VFD), electroluminescent (EL) and light emitting diode (LED). As the amount of information increases, people receive and process large amounts of information daily, a large proportion of which is visible. In this way, the display is required not only to display simple text symbols, but also be able to display image information and have a larger capacity.
