摘要
为了获得低成本大屏幕自由立体显示器,采用了DLP 投影的技术方案。通过模拟柱透镜光路,分析了立体视区特性。按照自由立体显示的结构和原理,计算出立体视区光能分布图。理论上证明了在最佳观看距离可获得没有互扰的立体影像。研究了最佳观看距离和像素匹配的设定方法,给出观看较好立体效果的范围。立体视区的研究协助了立体显示器的设计,最终获得了具有较好立体感和临场感的150 英寸大屏幕立体显示器。
Abstract
To obtain low-cost, super-large-panel autostereoscopic display, and the scheme of 3D monitor based on Digital Light Projection (DLP) was adopted. By simulating the light path of lenticular lens, the characteristics of stereo viewing zones were analyzed. According to the structure and principle of the display, the light distribution figure of stereo viewing zones was calculated. Viewers who stay at the optimal viewing distance can see good stereo images without crosstalk. The setting method of the optimal viewing distance and pixel matching was studied, and the range for the better stereo images was provided. The study on the stereo viewing zones is useful for the design of such autostereoscopic display devices and achieves 150-inch-large panel stereo display with good telepresence and three-dimensional effect.
