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.

与液晶掺杂后这类染料表现出许多光电特性,如具有宽液晶示视角、增加示亮度。

Also some liquid crystal displays depend on, demonstrated body itself which the modulation outside light realizes nonluminous, does not stimulate the eye, is not easy to be weary and so on the merit.

有液晶示靠调制外界光来实现，示体本身不发光，不刺激眼睛，不易疲劳优点。
