单色显示管的应用领域比电视显象管大,品种也比显象管多。屏幕尺寸从3.8cm 到51cm,1/10余辉时间从几十微秒到几百毫秒,分辨率从中等程度到超高程度的系列产品共有20余种。随着应用研究的不断深化,评价单色显示管的质量特性亦分得越来越细,大体上如图1所示。一、显示显示是指显示管工作时构成画面的基本要素。它包括分辨率、亮度、对比度和发光颜色。(一)分辨率分辨率是指在图象上能分辨最小细节的能力,通常用亮暗交替的线条总数表示。大家知道,现行电视显象管的扫描线数分辨率650行已达要求。但是,显
Monochrome display tube than the TV picture tube, variety is also more than the picture tube. Screen size from 3.8cm to 51cm, 1/10 afterglow time from tens of microseconds to hundreds of milliseconds, the resolution from the medium to high degree of a total of more than 20 kinds of products. With the continuous deepening of applied research, the quality characteristics of monochromatic display tubes are also getting more and more subdivided, as shown in Figure 1. First, the display shows that the display tube work constitutes the basic elements of the screen. It includes resolution, brightness, contrast and lighting color. (A) resolution The resolution refers to the ability to distinguish the smallest detail in the image, usually expressed in terms of the total number of lines alternating with light and dark. As we all know, the current video tube scanning line resolution of 650 lines have reached the requirement. However, significant
