A full resolution autostereoscopic three-dimensional (3D) display prototype is developed. It is composed of a time division thin film transistor liquid crystal display panel with an optical controlled birefringence liquid crystal polarization switch and a polarizer parallax barrier. Fast driving circuits operating at 120-Hz frame rate are fabricated. The 3D images on the display have the same resolution as the corresponding two-dimensional images, which is significantly different from conventional parallax barrier autostereoscopic 3D displays having degraded 3D image resolution. 相似文献

针对观看自由立体显示器存在人眼焦点调节和集合不一致的根本生理问题,及观看时间稍长将引起立体观看视疲劳,甚至危害视觉健康的问题。提出了一种对自由立体显示器视疲劳程度进行预测的方法,由三个不同的立体观看视疲劳参数——视差值、视频帧率和串扰度组合得到27段立体测试视频,让观看者观看这些视频得到主观评价数据,采用多元线性回归的统计方法处理评价数据确定了自由立体显示器视疲劳的多元线性回归模型,并根据此模型对待评估立体视频的视疲劳程度进行有效预测。这种方法避免了反复的主客观评价对视觉系统的危害,减少主客观评价信息收集的复杂性。最重要的是,该模型能快速预测自由立体显示器视疲劳程度。 相似文献

A multi-view three-dimensional (3D) display provides a more realistic experience than a two-view 3D dis- play. Therefore, a multi-view 3D display with high brightness based on a parallax barrier is proposed. The parallax barrier in the 3D display has a gradient transmittance with enhanced frequency character- istic, which indicates that the aperture ratio of the parallax barrier can be increased, thereby improving brightness. Gradient transmittance is also helpful in reducing crosstalk. A prototype of the 3D display is developed. Experimental result shows that the 3D display has higher brightness than a conventional display. In addition, crosstalk is limited at a low level. 相似文献
