Microprism brightness enhancement film

The utility model discloses a microprism brightness enhancement film which comprises a lower brightness enhancement film body, the lower brightness enhancement film body is provided with a first tip wave crest prism and a trapezoid wave crest prism, the first tip wave crest prism and the trapezoid wave crest prism are distributed in a staggered mode, and an upper brightness enhancement film body adheres to the trapezoid wave crest prism. The upper brightening film is provided with a second tip peak prism and an arc peak prism, and the second tip peak prism and the arc peak prism are distributed in a staggered mode. The light-transmitting effect is guaranteed, the increment effect is optimized, meanwhile, the arc wave crest prism of the lower brightening film bonded with the upper brightening film is changed into the trapezoid wave crest prism with the trapezoid section, it can be guaranteed that the contact area is large enough, and therefore the bonding stability effect is improved. 本实用新型公开了一种微棱镜增亮膜，包括下增亮膜，下
