Abstract

The high-resilience and high-brightness brightness brightness enhancement film comprises a prism layer, a base material layer and a back coating structure layer, which are arranged in sequence; the prism layer comprises a first prism structure and a second prism structure, the cross section of a prism of the first prism structure is triangular, and prisms of the second prism structure are evenly arranged between prisms of the first prism structure. The upper portion of each prism of the second prism structure is provided with two upper edges, and the highest position of the first prism structure is flush with the highest positions of the upper edges. Through the design, the brightness enhancement film can rebound faster, the brightness is higher, and the preparation method is simpler and more convenient.

Description

technical field [0001] The invention relates to the technical field of brightness enhancement films, in particular to a brightness enhancement film with high resilience and high brightness. Background technique [0002] Backlight modules currently on the market generally require multiple prisms to be assembled, but multiple prisms are prone to scratches during the assembly process, resulting in low luminance of the backlight module. On the other hand, most of the brightness enhancement films currently on the market have a common prism structure, while other complex brightness enhancement film structures can meet the luminance requirements of the backlight module, but the processing technology is relatively complicated. Therefore need to make improvement to this. Contents of the invention [0003] The present invention provides a new brightness-enhancing film with high resilience and high brightness, aiming at the defects of low luminance of the backlight module of the lum...
