计算机显示器

一台实验室里的电脑显示器

电脑显示器(Computer Monitor),又称视频显示器(visual display unit),是电脑的电子可视化显示器的一种。它亦是显示器的最常见一种。现代的荧光幕一般会以TFT-LCD薄身设计为主,而旧式厚身的是以CRT形式所制。

原来电脑荧幕只是用作数据传输,而电视机则用作娱乐。在1980年起,电脑荧幕可以两者兼用,电视亦加入部分电脑功能。现时最普遍的比例是4:3或16:9。

历史

[编辑]

俄罗斯科学家发明家鲍里斯·罗辛在1907年将一些简单的单色几何图形显示在使用CRT(Cathode Ray Tube)制作的屏幕上,这便是显示器的雏形。

第一台真正意义上的显示器由苹果公司在1922年制造,使用在其产品Apple I上,此为CRT显示屏技术的首次商用。

早期的CRT技术主要应用在电视柏林奥运会在1936年首次应用了实况转播技术,直接促进了CRT电视的普及。同年,英国电视开始销售的马可尼702(Marconi 702)电视为最早的CRT电视之一。[1]
