Structure of light control membrane |
摘要 |
A structure of light control membrane is mainly comprised of a single layer of light-conducting membrane as a substrate, wherein the surface of the light-conducting membrane particularly has an opaque zone in spiral shape or multi-layer circular rippling wave shape. When a user views an image through the light-conducting membrane, the opaque zone in spiral shape or multi-layer circular rippling wave shape will make the image visible only within a specific range of viewing angle while, out of the specific range of viewing angle, the image is invisible.
