介绍了多媒体大屏幕终端的设计技术。它主要解决ＰＣ机专用显示器，对动态图象和静止图象显示效果存在的不足，以及ＴＶ在显示文本文件时分辨率不高、画面抖动的问题。探讨了大屏幕、高分辩率、高质量动态、静态图象显示和文本显示的优化技术。通过对自动输入信号进行ＤＡＣ自动控制，在削波电路的作用之下，保持高压发生电路和偏转电路的稳定性。最大限度地解决了复合视放电路的对比度和高清晰度之间的矛盾。另外，在多媒体大屏幕终端结构设计方面提出分体组合式设计方案，为家庭影院三电一体提供了较理想的选择。
Introduced the multimedia big screen terminal design technology. The utility model mainly solves the problems that the special display of the PC has the defects of the display effect of the dynamic image and the still image and the low resolution and the picture jitter of the TV when displaying the text file. This paper discusses the optimization technology of big screen, high resolution, high quality dynamic, static image display and text display. Through the automatic input signal DAC automatic control, under the action of the clipping circuit to maintain high-voltage generating circuit and the deflection circuit stability. The maximum solution to the composite display circuit contrast and high-definition conflicts. In addition, the multi-media large-screen terminal structure design proposed split modular design for the home theater three-in-one provides an ideal choice.
