| 摘 要： | 固态体积式真三维立体显示系统主要由数据传输,图像处理模块,高速彩色投影光路模块,显示模块(显示体)以及外围控制电路组成.显示模块由多层液晶光阀组成,光线透过显示体后能量衰减严重,造成显示画面黯淡,.模糊,此外,由于光阀响应时间慢,系统刷新频率低,屏幕存在严重的闪烁问题.本文通过在液晶中添加少量聚合物和手性物添加剂制备出快速响应的聚合物稳定胆甾相液晶光阀,其开态透过率达到88％,响应时间小于1 ms.将其应用于真三维立体显示系统,显示画面清晰稳定,无闪烁.

| Abstract: | A solid-state volumetric true 3D display consists of a data transmission, image processing module, a high-speed color projection module, a display module and control circuits. The display module contains of light shutters, which display a dark and fuzzy picture due to the brightness decay when lights transmits. In addition, the display has a serious problem of screen flicker owing to the low response time and low refresh rate. This paper exploits a new polymer stabilized cholesteric texture shutter by adding a small amount of ploymer and chrial dopants to liquid crystal. The maximal transmittance is 88% and the response time is lower than one millisecond. When applied in true 3D display, it can display a clear, stabilized and non-flicker picture, completely satisfying the demands of true 3D display. |
