What is Brightness Enhancement Film?
Brightness Enhancement Film(Prism film),also known as BEF, is an optical film with a uniform prismatic pattern precision molded on the surface of PET, which has excellent transparency, using acrylic resin. By assembling it in front of a backlight source, the light emitted from the light source is gathered in the direction of the user of the display device, and the brightness of the front side can be increased by approximately 100% (in the case of two orthogonal sheets, there is a molded vertical BEF). Furthermore, light that is not utilized outside the viewing angle is recycled according to the effect of light re-reflection and gathered at the most appropriate angle toward the user.

Characteristics of Brightness Enhancement Films :
- 1. Increases brightness by concentrating dispersed light from a light source in the frontal direction.
- 2. When 2pcs prism films are used orthogonally, the brightness of the front side can be increased by approximately 100%.
- 3. The thickness is only 125-275μm, which has no effect on the thickness of the display device.
