介绍了一种使用单片玻璃基板和各向异性聚合物膜的轻型、共面转换液晶显示(IPS-LCD)技术。液晶分子由伸长的聚合物膜内的颗粒排列。各向异性聚合物膜的取向性能与聚酰亚胺(PI)摩擦层相当。良好的液晶取向性能使新器件的对比度(514:1)、驱动电压和响应时间都能够与双玻璃基板LCD相比拟。这种各向异性膜也能作为拓宽视角的相位补偿膜来使用。该技术特别引人注目之处在于制作单基板显示器,同时它也具有实现双层宾主显示和IPS-LCD柔性显示的潜在应用。
A lightweight, coplanar liquid crystal display (IPS-LCD) technology using a monolithic glass substrate and an anisotropic polymer film is presented. Liquid crystal molecules are arranged by particles in the elongated polymer film. The anisotropic polymer film has an orientation property comparable to a polyimide (PI) friction layer. Good liquid crystal alignment enables the new device’s contrast ratio (514: 1), driving voltage and response time to be comparable to double-glass LCD substrates. Such an anisotropic film can also be used as a phase compensation film for widening the viewing angle. This technology is particularly compelling in the production of single-substrate displays, but it also has the potential for double guest display and IPS-LCD flexible display.
