摘要

针对光栅型自由立体显示方案易存在串扰和莫尔条纹的问题,提出一种莫尔条纹和可视区域均在可接受范围内的倾斜锯齿交错光栅设计方法,该方法在斜光栅结构基础上以一个像素高度的一半为单位对光栅进行分段,将相邻两段狭缝用对称三角形狭缝代替.该结构与斜光栅相比,减少了通过同一狭缝看到相邻子像素而产生的相互串扰,即减小了斜光栅存在的视点间的串扰,扩大了可视区域范围.仿真及实测结果表明倾斜锯齿交错光栅比斜光栅可视区域增加了25%,而莫尔条纹亮度只减少4.5%,具有一定的实用价值.

Abstract

In order to eliminate the Moiré fringe and crosstalk existed in parallax barrier based autostereoscopic display, a new design of slanted zigzag staggered parallax barrier was presented for autostereoscopic display. The slits were divided into sections at half the height of a pixel and the adjacent two sections were symmetrical triangles based on slanted barrier. This method can decrease the probability of the perceived adjoining sub-pixel seen through the same slit when compared with the slanted barrier, thererfore, crosstalk can be reduced and the field of viewing zone can be extended. The simulated and measured results show that the proposed method can increase the viewing zone by 25% more than that of slanted barriers with a decrease of only 4.5% of the Moiré fringe. And it has higher practical value for autostereoscopic display.
