目前常用的三维显示技术，一般是通过人眼的双目视差和视觉暂留效应实现的三维效果。由于丢失了深度信息，会引起辐辏调节冲突，使观看者产生不适感。光场显示是通过复现物体表面光线的真三维显示技术，其拥有良好的用户体验，符合人们对于未来显示的需求。文章梳理了各种光场显示技术的原理和特点，分析了国内外光场显示技术的发展现状，整理了国内外的研究进展和代表性样机的性能，最后对我国光场显示的发展进行了展望。我国光场显示虽然起步稍晚，但经过多家科研机构的一致努力，已在国际上拥有一定的地位。

Currently， the most widely used three-dimensional（3D） display technology often uses the binocular parallax and transient visual effect of the human eye to generate the three-dimensional impression. The lack of depth information will lead to a conflict in the convergence adjustment and discomfort for the viewer. A true 3D display technology， light field display reproduces light on an object's surface， offers a positive user experience， and it satisfies people's needs for future displays. In this paper， the principles and characteristics of various light field display technologies were combed， the development of light field display technologies at home and abroad were analyzed. Then， the research progress and the performance of representative prototypes were sorted out. Finally， the development of light field display in China was prospected. Despite China's light field exhibition getting off to a rather late start， it has earned some notoriety abroad thanks to the combined efforts of various academic organizations.
