We developed a waveguide liquid crystal display from a liquid crystal (LC)/polymer composite. It does not need polarizers or color filters. It is illuminated by color LEDs installed on its edge. The light produced by the edge LEDs is coupled into the display and then waveguided through the display. When the LC is in the transparent state, the incident light is waveguided through and no light comes out of the viewing side of the display. When the LC is in the scattering state, the incident light is scattered and comes out of the display. It can be used either for transparent display or for direct view display. The composite has a submillisecond response time, and a field sequential scheme can be used to display full color images. Because the display does not need polarizers or color filters, its energy efficiency is much higher than current liquid crystal displays.
我们用液晶(LC)/聚合物复合材料研制出了一种波导液晶显示器。它不需要偏振器或彩色滤光片。它由安装在其边缘的彩色发光二极管照亮。边缘发光二极管产生的光耦合到显示器中,然后在显示器中波导传播。当液晶处于透明状态时,入射光在显示器中波导传播,没有光从显示器的观看侧射出。当液晶处于散射状态时,入射光被散射并从显示器射出。它既可以用于透明显示,也可以用于直视显示。该复合材料具有亚毫秒级的响应时间,并且可以采用场序制方案来显示全彩图像。由于该显示器不需要偏振器或彩色滤光片,其能量效率比目前的液晶显示器高得多。
