摘要:
An anti-peeping module provided by an embodiment of the application includes a plurality of light transmitting films, each including at least two light transmitting sub-films having different refractive indexes which are disposed in a laminated manner, and a first optical path modulating layer on one side of the plurality of light transmitting films, the first optical path modulating layer comprising a plurality of zigzag structures, the and being configured to allow light entering into the plurality of light transmitting films at a Brewster incident angle to exit from the anti-peeping module in a travelling direction perpendicular to a plane where the anti-peeping module is located.
