Abstract For traditional integral imaging display systems with usual lens array, there is the same viewing angle in the horizontal and vertical direction. Due to usual display has vertically long sub-pixels, this sub-pixel shape makes the view density be lower in vertical direction than the horizontal one. Here, a clear full-parallax 3D light field display with uniform view density along the horizontal and vertical direction is demonstrated. The proposed 3D display system consists of a collimated backlight source, a 31.5-inch LCD with the resolution of 3840 × 2160, an aspherical cylindrical compression lens (ACCL) array and a holographic functional screen (HFS). The ACCL array is used to compress the vertical viewing angle to increase the view density in the vertical direction. After combining the collimated backlight, the aberration of the system is suppressed. Compared with traditional integral imaging display, the viewpoint density in the vertical direction is increased and the aliasing phenomenon is reduced. Experimental results show that a clear full-parallax light field 3D image can be achieved in the horizontal viewing angle of 81 degrees and the vertical viewing angle of 27 degrees.

全视差 3D 光场显示，水平和垂直方向具有均匀的视野密度

摘要 对于采用普通透镜阵列的传统整体成像显示系统，水平和垂直方向的视角是相同的。由于通常的显示器具有纵向较长的子像素，这种子像素形状使得垂直方向的视图密度低于水平方向。这里展示了清晰的全视差 3D 光场显示，在水平和垂直方向上具有均匀的视图密度。所提出的 3D 显示系统由准直背光源、分辨率为 3840 × 2160 的 31.5 英寸 LCD、非球面柱面压缩透镜 (ACCL) 阵列和全息功能屏幕 (HFS) 组成。ACCL阵列用于压缩垂直视角以增加垂直方向的视角密度。结合准直背光后，系统的畸变被抑制。与传统的整体成像显示器相比，增加了垂直方向的视点密度，减少了混叠现象。实验结果表明，在81度的水平视角和27度的垂直视角下可以实现清晰的全视差光场3D图像。
