中文摘要： 三维显示承载着人们对再现客观世界的向往，是世界各国大力发展的新型显示。虽然目前眼镜式三维显示已较为成熟，但是不借助辅助物的裸眼三维显示仍然存在分辨率低，视野角较窄和三维显示特性较差等的问题。此申请将蓝相液晶技术应用于动态液晶微透镜，时序控制液晶透镜的折射率分布，投射不同视点图像至相应观察点的空间位置，形成广视角高分辨率裸眼三维显示。本项目将研究其中的关键科学问题，包括研究快速响应蓝相液晶材料的器件特性与动作机理，优化菲涅尔式折射率分布的蓝相液晶透镜与液晶聚合物透镜的结构模型，通过动态调制液晶透镜和时序二维显示，实现二维和三维影像的等分辨率转换，获取广阔的三维视野角，消除相差引起的串扰；并结合研究影响系统静态串扰特性的平面准直光源系统中微结构的作用，以及探索液晶透镜动态折射率分布对三维显示动静态综合串扰特性的影响因素，消除相邻像素光路引起的串扰，降低系统综合串扰，实现优质三维光特性。

英文摘要： As a future display technology, 3D display has been rapidly developed in all regions of the world. It makes people realize their dreams for the reproduction of the true world with a more interesting and real viewing experience. The stereoscopic displays have been developed for a long time and have been in commercialization recently. But for the autostereoscopic displays which need no aid of the auxiliary devices, there are still some issues of optical property, such as low resolution, narrow 3D viewing angle, relatively high crosstalk. In our application, the blue phase liquid crystal (LC), a kind of macro isotropic LC material, will be applied in dynamic LC lens due to its microsecond level response time. As the refractive index profile of the LC lens is sequentially controlled by electric field, the images of different view point can be sequentially projected into the different spatial positions to make the 3D viewing zone which is same as the 3D viewing zone made by conventional lenticular autostereoscopic displays. With the above technology, the display with dynamic LC lens can achieve not only the high resolution which is same as that of 2D display, but also wide viewing angle in 3D viewing zone. In addition it can degrade the crosstalk to improve the 3D performance by eliminating aberration of lens. This p
