在液晶投影顯示系統內,當光線從光源射出,高效率偏極化光線經過投影系統架構,最後在顯示螢幕上會得到一個高亮度和高均勻度的畫質。
這篇論文提出照明系統設計評估應用於液晶投影顯示器以產生均勻化和矩形光源分佈。短弧距燈泡、優化反射鏡面和最佳integrator設計應用於投影系統可以得到最佳的光使用效率並增加畫面均勻度。此高效率照明設計可應用於前投影顯示器和大尺吋後投電視。
In compact projection display, a luminous flux from a light source into a linear polarized beam at high efficiency and providing high-brightness high-uniformity image whose illuminace is uniform all over the projection screen is realized.
This paper presents that high-collection optical illumination system with high power lamp is designed to generate a uniform and a rectangular light source for LC panel. A short arc lamp, an optimized reflector design, and an optical integrator enable a compact system to maximize light efficiency and to increase illumination uniformity. Then we discuss how the geometrical optical efficiency of the system can be boosted to approach the theoretical maximum. Efficienct optical illumination design that provides a brightness and high performance image can be applied both with front projector and with large-size rear projection TV.
