在信息技术高速发展的今天,电子显示器件在人和机器之间担任重要桥梁的角色。通常,我们可以根据电子显示器件的工作原理把能够主动在显示媒介上发光来显示画面的显示器件划分为发光型显示器件;把不主动发光,而是通过间接调制光线来显示画面的显示器件划分为受光型显示器件。发光型显示器件常见的几种具有代表的有:阴极射线管(CRT)、等离 Today, with the rapid development of information technology, electronic display devices play an important bridge between people and machines. Generally, we can divide a display device capable of actively displaying a picture on a display medium into a light-emitting display device according to the working principle of the electronic display device; a display device division device that displays a picture by indirectly modulating light without actively emitting light For the light-type display device. Several common types of light-emitting display are: cathode ray tube (CRT), plasma
