本文概略地介绍了CRT终端显示器的特点、用途、分类和使用要求,结合数字信号CRT终端显示器对清晰度这个重要技术指标进行了详细的分析和举例说明,并指出不能用电视技术中电视线数这个参数的概念来区分显示器的清晰度等级,只用字符容量来评价显示器分辨能力的高低也不确切,应该采用显示密度作为衡量标准。本文列出了部分国外高清晰度彩色显象管和CRT显示器,这有助于按照不同的技术要求来正确地设计和选择CRT终端显示器。
This article briefly introduces the CRT terminal display features, uses, classification and requirements, combined with digital signal CRT terminal display resolution of this important technical indicators were described in detail and examples, and pointed out that the TV can not be used in the TV line The concept of this parameter to distinguish the display resolution level, only the character capacity to evaluate the level of resolution of the display is not precise, the display density should be used as a measure. This article lists some of the foreign high-definition color CRT and CRT monitors, which help to properly design and select CRT terminal monitors according to different technical requirements.
