Current efforts with light field displays are mainly concentrated on the widest possible viewing angle, while a single viewer only needs to view the display in a specific viewing direction. To make the light field display a practical practice, a super multi-view light field display is proposed to compress the information in the viewing zone of a single user by reducing the redundant viewpoints. A quasi-directional backlight is proposed, and a lenticular lens array is applied to achieve the restricted viewing zone. The eye-tracking technique is applied to extend the viewing area. Experimental results show that the proposed scheme can present a vivid 3D scene with smooth motion parallax. Only 16.7% conventional light field display data are required to achieve 3D display. Furthermore, an illumination power of 3.5 watt is sufficient to lighten a 31.5-inch light field display, which takes up 1.5% of the illumination power required for planar display of similar configuration.
目前对光场显示器的研究主要集中在尽可能宽的视角上，而单个观看者只需要在特定的观看方向上观看显示器。为了使光场显示器具有实用性，提出了一种超级多视角光场显示器，通过减少冗余视点来压缩单个用户观看区域内的信息。提出了一种准定向背光源，并应用柱面透镜阵列来实现受限的观看区域。应用眼动跟踪技术来扩展观看区域。实验结果表明，该方案能够呈现出具有平滑运动视差的逼真3D场景。实现3D显示仅需16.7%的传统光场显示数据。此外，3.5瓦的照明功率足以点亮一台31.5英寸的光场显示器，这仅占类似配置平面显示器所需照明功率的1.5%。
