MMTV研制技术问题

On the Subject of design for MMTV

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。

This paper introduces the technology of multimedia monitor TV (MMTV) in design, which overcomes the shortage of PC monitor`s poor displaying moving pictures and still image, and also it tries to solve the problem of low definition and trembling pictures of TV in displaying text file .The technology makes it possible for the large screen size, high definition, high quality display of moving pictures and text file. Using DAC auto control of auto input signals and under the control of wave clipper circuit, the stability of high voltage generator circuit and deflection circuit is ensured,which,to the maximum,solves the technical contradiction between contrast and high definition of complex video display circuit. Moreover, this paper also provides a new structure design in fission combination style, a better choice for family theater in future.
