摘　　要：一维狭缝光栅实现平面三维显示具有低成本、光栅参数易于改变和无需对焦的优点,但存在遮挡画面影响亮度的缺点;二维透镜阵列具有全视差且深度感知自然的优点,但存在显示像素低和观察视角小的缺点。为了同时兼顾上述两种方案的优点,结合一维狭缝光栅和二维透镜阵列提出了一种基于二维方孔光栅的平面立体显示方案。Lighttools软件仿真实验结果表明:基于二维方孔光栅的平面三维显示原理可行,其像质因子略小于一维狭缝光栅的像质因子,但继承了一维狭缝光栅和二维透镜的优点,是实现平面三维显示的一种新的发展方向。One-dimension slit barrier for flat-panel 3D（three-dimension） display has some advantages of low cost and changing parameters easily and no need to focus,but it has a little lower brightness because of blocking light.Two-dimension lens array has the advantages of full parallax and natural depth perception,but its viewing-resolution and viewing-angle are limited.In order to combine the advantages of the above-mentioned two kinds of scheme,a new flat-panel 3D display scheme based on 2D（two-dimension） square hole barrier is proposed according to one-dimension slit barrier technology and two-dimension lens array scheme in the paper.The results of simulating experiment of Lighttools indicate that the image quality factor of 2D square hole barrier is slightly less than one-dimension slit barrier＇s,but it has the advantages of one-dimension slit barrier technology and two-dimension lens array,and it is a new direction of development for flat-panel 3D display.
