Abstract
Disclosed are a wedge-shaped light guide plate and a collimating backlight module. The wedge-shaped light guide plate includes an incident surface at a thick end, a first light-emitting surface, a second light-emitting surface and two side surfaces, wherein a wedge angle is formed between the first light-emitting surface and the second light-emitting surface, and an incident micro-prism structure is disposed on the incident surface. The collimating backlight module is composed of at least one wedge-shaped light guide plate, a strip-shaped light source disposed on one side of the incident surface of the wedge-shaped light guide plate, a reverse prism film disposed on one side of the first emergency surface, and a reflecting film disposed on one side of the second emergency surface. Half of the light-emitting angle of the collimating backlight module can reach ±25°, which is superior to the anti-pry angle of most privacy films on the present market.
