受限于微透镜的数值孔径和像差问题，目前移动视差式立体显示屏存在多视场空间、视场区之间存在视场跳变、主视场空间角度小、显示效果模糊等问题.本文基于离散采样思想，分析了移动视差型三维显示系统的工作机理,结合加工工艺，设计了复合曲面反射层的双层微透镜阵列屏.仿真结果表明: 所设计显示屏的视场观看空间角可提升到60°，相对于传统的三维显示屏，双层微结构显示屏可有效提高视场角和显示性能.

Motion parallax stereoscopic display exists the problems of multi-viewing field, sudden jumps between subzones, narrow main watching field, blurring etc, because of its low NA and aberration. In this paper, the idea of discrete sampling was applied to analysis the motion parallax stereoscopic display system. Based on the analysis and considering the manufacture procedure, a double micro-lens array screen combined with curve reflection surface was proposed. The simulation results show that this design makes improvement on the 3D display performance and viewing angle achieves almost 60 degrees. This proposal is of great significance to promote the practical application of the three-dimensional system.
