Abstract
Official abstract text for this publication.
Provided is a peep prevention display, wherein a peep prevention film layer is provided on the light exit side of the peep prevention display, and the peep prevention film layer has a mesh structure; meshes of the mesh structure are arranged corresponding to sub-pixel units or pixel units of the display, and the peep prevention film layer comprises a P electrode lead layer, a P type semiconductor layer, an N type semiconductor layer and an N electrode lead layer. Since the peep prevention display has a small display angle of view, it can prevent peep by a person from side angle of view while providing image display for a user viewing from the front, so as to effectively protect personal privacy and business secret. In addition, the light blocked by a peep prevention film layer can be converted to electric energy, thus achieving an effect of self electricity generation.
