Tracepro在OLED立体显示设计中的应用

Application of Tracepro in the autostereoscopic display of OLED

通过Tracepro光学软件对基于视差照明原理的立体显示系统进行建模,设定光栅常数及栅屏距离等参数,模拟显示器件的几何光路,来验证基于视差照明原理的立体显示器的可行性。实验显示奇、偶像素列图像被成功分离,与视差照明原理的预期结果相符。为裸眼立体显示器的设计及其立体视觉性能评价提供理论参考。

Basic function of parallax illumination is to send pixels in odd or even columns on OLED screen into left or right eyes resulting in separation of two pictures and makes the person who sees them have stereo feeling. The design of a parallax grating is the most important factor when designing an autostereoscopic clisptay which is based on parallax illumination pr/nciple. The distance between parallax grating and screen, and the grating constant are key issues. This paper tries to use Tracepro optic design software to realize the simulation of autostereoscopic display ＂s ray path and validate the feasibility of stereoscopic display based on parallax illumination principle. With a given distance between gating and screen and gating constant, it is successful to separate the pictures of odd or even columns.
