屏幕分辨率的研究近年来得到了很大发展,它对于提高信息显示容量,丰富画面层次具有重要意义.目前,屏幕分辨率高的器件多用于电子计算机、电子显微镜等精密仪器的终端显示,用以显示文字、符号、曲线和图表.通常,人们把屏幕分辨率高于1000线的显示真空器件称作显示管(Display Tube).显示管在品种和市场占有率方面,日本松下公司处于领先地位.不久前,松下报道了可显示12,672(192×66)个字母的超高分辨率显示管,每个字母由81(9×9)个荧光点组成.1982年,《松下技术评论》(National Technical Report)出版了“显示技术特集”,特集中涉及屏幕分辨率的论文占了相当比重.国内的一些单位正在积极试制显示管,有几个型号已经批量生产.显示管的显示能力,由于高分辨化而大大地提高了.高分辨屏幕的显示管越来越受到人们的重视. 显示管可分为单色和彩色的两种.目前,国内着重单色显示管的研究.单色显示管要实现高分辨率,必须解决两个关键问题.(1)如何把电子枪发射的电
Research on screen resolution has been greatly developed in recent years, which is of great significance to improve the information display capacity, rich screen level.At present, the devices with high screen resolution are mostly used in the terminal display of precision instruments such as electronic computers and electron microscopes, Display text, symbols, curves, and charts Typically, a display vacuum device with screen resolution greater than 1000 lines is called Display Tube. Display Tube Panasonic Japan leads the way in variety and market share. Not long ago, Matsushita reported ultra high resolution display tubes displaying 12,672 (192 × 66) letters, each consisting of 81 (9 × 9) phosphor dots. In 1982, National Technical Report published a “display technology feature set,” special screen resolution of the papers accounted for a considerable proportion of the domestic units are actively trial display tube, there are several models have been mass production tube display capabilities, due to high resolution And greatly increased.High resolution screen display tube more and more people’s attention.The display tube can be divided into two kinds of monochrome and color.At present, the domestic Research monochrome display tubes. To achieve a high-resolution monochrome display tubes, must address two key issues. (1) how the emission electron gun power
