由于彩色高分辨力监视器,大容量 CMOS 存储器,及微处理机的发展,光栅扫描式彩色图形显示器已基本上取代了早期的随机扫描式图形显示器。并使个人计算机也开始进入了高质量图形显示的领域。早期用于图形显示的双色存储型 CRT 管和能显示3～4色的穿透式 CRT 管已只在少量特殊场合应用。隐罩式的高分辨力彩色 CRT 管已控制了市场。目前分辨力在1000线以上的彩色隐罩管已有很多工厂能够生产。表1列出了目前日立公司生产的主要 CRT 管规格。用其制成的 C20c-2073A 彩色20时监视器分辨力可达1280×1024,光点直径小于0.3mm,放大器带宽达76MHz,行频为64KHz。价格一般3000美元左右。14时分辨力640×400的彩色监视器在日本已成为
Due to the development of color high-resolution monitors, high-capacity CMOS memories, and microprocessors, raster-scan color graphic displays have largely replaced earlier random-scan graphic displays. And personal computers have begun to enter the field of high-quality graphics. The earlier dual color storage CRTs used for graphic displays and penetrating CRTs capable of displaying 3 to 4 colors have been used for only a few special applications. Hidden high-resolution CRT color CRT has controlled the market. At present, the resolution of more than 1000 lines of color hidden tube has many factories to produce. Table 1 lists the main Hitachi CRT tube specifications. C20c-2073A made with its 20-color monitor resolution of up to 1280 × 1024, the spot diameter of less than 0.3mm, the amplifier bandwidth of 76MHz, line frequency is 64KHz. The price is generally about 3,000 US dollars. Resolution at 14 o’clock 640 × 400 color monitor has become in Japan
