本文介绍了一个结构简单、性能价格比高的单板微型机CRT显示器的设计、工作原理及使用方法。该显示器能显示ASCII码、图形、专用汉字,解决了单板机在工业过程控制、数据采集应用中显示功能不足的问题。本文还提出抑制显示器更换画面间的随机干扰及提高显示清晰度的新方法,实践证明这两种方法是简单而有效的。 This article introduces the design, working principle and usage of a single-chip microcomputer CRT display with simple structure and high performance-price ratio. The display can display ASCII code, graphics, special Chinese characters, solves the single board machine in industrial process control, data acquisition applications display function of the problem. In this paper, we also propose a new method to suppress the random interference between displays and to improve the display resolution. These two methods are proved to be simple and effective.
