液晶投影显示系统中的透镜阵列方式

Lens Array Method Used in LCD Projective System

首先对大屏幕液晶投影显示系统进行分析，并在系统设计中采用透镜阵列方法提高系统的光学性能，针对光学透镜阵列方法进行探讨研究，给出透镜阵列的设计方法和设计参数，显示系统采用双排复眼透镜，在１９０Ｗ的金属卤化物灯的情况下可达到４００ＡＮＳＩ流明的光能量输出，对比度大于１００１，均匀性大于９０％，且显示效果良好，性能优异。

In this paper, a LCD projective system is discussed. We use lens array method in the LCD projection system to improve the optical performance. The design method and parameter are discussed. As a result, the LCD projector with high optical performance is developed. The output of the projector is 400 ANSI lumens with 190W metal halide lamp and the uniformity of display image is over 90%. Good optical performance and outstanding picture quality are achieved.
