The photoemissions are showed after dichroitic azo dyes doping with liquid crystal,such as widening angle of view, improving light in display and so on.

与液掺杂后这类染料表现出许的光电特性,如具有宽液显示的视角、增加显示亮。

Many parameters are required to describe their performance, which is transmission ratio, extinctivity ratio, angle of view field, splitting angle, etc.

光偏光棱镜技术参数较，透射比、消光比、视场角、分束角、长孔径比。
