The invention relates to an electronic rearview mirror which comprises a liquid crystal box and is characterized by further comprising a polariscope mask. The liquid crystal box is a vertical alignment liquid crystal box, a negative liquid crystal layer doped with dichroic dye is arranged in the vertical alignment liquid crystal box, and the vertical alignment liquid crystal box is provided with a liquid crystal alignment axis capable of determining the deflection direction of negative liquid crystal molecules in an electric field; the polariscope mask is arranged on the rear side of the liquid crystal box, and the polariscope mask is provided with a reflection polarization axis parallel to the liquid crystal orientation axis. The electronic rearview mirror is high in response speed and transmittance, the structure can be simplified, and a polaroid is omitted, so that a series of problems caused by the existence of the polaroid can be avoided.
本发明涉及一种电子后视镜,包括液晶盒,其特征在于:还包括偏光镜面膜;所述液晶盒为垂直配向液晶盒,垂直配向液晶盒内设有掺杂有二色性染料的负性液晶层,垂直配向液晶盒具有能确定负性液晶分子在电场中偏转方向的液晶取向轴;偏光镜面膜设置在液晶盒的后侧,偏光镜面膜具有与液晶取向轴平行的反射偏光轴。这种电子后视镜不仅响应速度快、透过率高,而且能够简化结构,省去了偏光片,由此可避免因存在偏光片而引起的系列问题。
