微显示背投电视的技术和市场新进展

背投影电视机是现代电视技术、光学技术和新材料技术结合的产物，其显示系统可采用CRT（阴极射线管）、PDP（等离子显示器）、LCD（液晶显示器）、DLP（数字光处理器）和LCoS（硅基液晶）等显示技术，后三种又称微显示技术，因为采用的是微型的显示器和电子元件，因而大大降低功耗和生产成本，减小体积和厚度。而且微显示背投影电视机图像较CRT背投亮度强，清晰度高，屏幕可以做大，寿命长，综合性能明显优越，极有发展前途。本文对此进行综述和分析。

New Development of the Technology and Market of Micro Display Rear Projection Televisions

Rear projection televisions are the achievement of the combination of modern television,optics and new materials technologies.Their display systems may be based on different technologies:CRT,PDP,LCD,DLP or LCoS,the last three types are also called micro-display technologies.Micro-display systems are made with small sizes display devices and electronic elements,thus consume less energy and are of lower production cost,consequently decrease the volume and thickness.Compared with televisions made with CRT,the image quality of these new ones is much better:higher brightness and sharpness,longer life,bigger screen size etc,so they have a promising future.this paper presents a review and analysis on this subject.
