Abstract:
A louver film display structure, including: a first and a second electrode; a plurality of louver structures extending between the first and the second electrodes light transmissive elements positioned between adjacent louver structures of the plurality of louver structures, wherein: when a first voltage level is applied to the first and the second electrodes, the louver structures provide a first viewing angle of each unit area of light of each light transmissive element based on a first state of the louver structures, and when a second voltage level is applied to the first and the second electrodes, the louver structures provide a second viewing angle of each unit area of light of each light transmissive element based on a second state of the louver structures, wherein the first voltage level is greater than the second voltage level and the second viewing angle is greater than the first viewing angle.
