介绍了多媒体大屏幕终端的设计技术，它主要解决了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，高分辨率，高质量动态，静态图象显示和文本显示的优化技术。

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.
