基于方形RGBW子像素排列的跟踪式自由立体显示屏

针对传统基于移动狭缝光栅的跟踪式自由立体显示中因观看者头部微动看到串扰立体图像的问题,提出了一种基于方形RGBW子像素排列和斜置狭缝光栅的跟踪式自由立体显示屏,通过创建具有固定宽度的无串扰视区,为不同观看者提供无串扰的立体图像。分析了自由立体显示屏的工作原理,给出了其参数计算公式。实际设计了基于提出方法和传统方法的跟踪式自由立体显示屏,并仿真了它们在最佳观看距离处水平方向上的亮度分布。通过对比分析,得出基于提出方法的跟踪式自由立体显示屏在最佳观看距离处获得了具有固定宽度的无串扰视区,从而保证了观看者始终观看到无串扰的立体图像。

An eye-tracking autostereoscopic display screen with RGBW square subpixel arrangement

In order to obtain steady-going view zones without crosstalk for eye tracking autostereoscpoic displays using dynamic parallax barrier,an autostereoscpoic display screen with RGBW square subpixel arrangement and tilted parallax barrier is proposed.The operation principle and the calculation equations of the display screen are given.The autostereoscpoic display screens based on the proposed and conventional structures are designed and their luminance distributions along the horizontal direction at the optimal view distance are calculated.The results show that the view zones without crosstalk for the proposed autostereoscpoic display screen are obtained at the optimal view distance.
