摘要
平面三维显示技术是近年来最新出现的虚拟现实显示技术,其最大的特点是观察者无需使用任何辅助附加设备,直接用肉眼就可看到屏幕上显示的三维图像。为推进三维显示技术的发展,进一步研究了视差立体成像原理,并据此介绍几种平面三维显示方法及其工作原理,包括障栅立体显示、微柱透镜阵列立体显示、偏振片立体显示和基于微柱透镜立体显示原理的多视点系统,阐述并分析了系统的优缺点。以日本三洋公司的四视角立体显示装置、南京大学的多视点三维显示系统和NEC液晶科技的HDDP三维显示系统为例,描述了国内外该项技术近期的研究现状,分析了存在的技术难点,展望了该应用领域的发展前景。
The flat 3-D display technology is a novel virtual reality technology, in which people can see 3-D stereoscopic images from a screen directly and do not require any device to be worn. To promote the develop- ment of the fiat 3 D display technology, this paper introduces the imaging principle of parallax pictures and some fiat 3-D display methods including barrier 3-D displays, micro-lens 3-D displays, polarizer 3-D displays, multi-view lenticular stereoscopic displays and so on. Then, it analyzes on the advantages and disadvantages about these methods. By taking the four-view autostereoscopic displays from Sanyo in Japan, multi-view 3-D displays from Nanjing University and the Horizontally Double-density Pixels(HDD.Ps) 3-D displays in NEC for examples, it introduces the recent research and potential development, describes technique problems, and forecasts the application prospects for the fiat 3-D display technology.
