[0002] The brightness enhancement film, also known as a prism sheet, is an optical film with a uniform prism pattern precisely formed on the surface of a prism sheet with very good transparency using acrylic resin. When assembled in front of a backlight source, the light emitted by the light source is concentrated towards the direction of the display device user, which can increase the front brightness. Moreover, the light not utilized outside the viewing angle is recycled according to the light re - reflection effect and concentrated towards the user at the most appropriate angle. The brightness enhancement film used on an LCD liquid crystal module is a brightness enhancement film with good stability for LCD liquid crystal modules.
