A thin film with an edge-protected light-leakage structure

Abstract

This utility model discloses a thin film with an edge-protected light-leakage structure, relating to the field of thin film technology. It includes a light guide plate with beveled sides. The angle between the side and bottom edge of the light guide plate is less than 90°. A light-absorbing layer is fixedly attached to the beveled side of the light guide plate. A reflective layer is attached to the outer side of the light-absorbing layer. A buffer protective layer is provided on the outer layer of the reflective layer. The light-absorbing layer, in conjunction with the reflective layer, directly reflects external light sources through the reflective layer, reducing the impact of external light sources on the edge of the light guide plate. The light-absorbing layer directly absorbs stray light scattered to the edge, constructing a "absorbing-reflecting" dual barrier. This achieves effective light absorption while reducing the thickness of the reflective layer, making it more suitable for the production of ultra-thin light guide plates.
