Film and coating enhancements to the cover glass or touchscreen reduce or change the characteristics of light reflected from the face of the displays. By recycling and redirecting normally lost light, film enhancements improve backlight brightness from 60% to 90%, depending on backlight types. VISDI can add films to eliminate diffuse reflections or change diffuse reflections into specular reflection.

DBEF, or Dual Brightness Enhancement Film, is a thin matte surface reflective

polarizer with tiny 90 degree triangular structures on the film surface. This film is used to boost display brightness through light control. Film enhancements work by recycling light absorbed by rear polarizer and by directing light upward through the display.

AR (Anti-reflectant) and AG (Anti-glare) film enhancements improve display performance by decreasing surface reflectance, usually less than 1%. This increases ambient light readability and viewing angles. Regular displays reflect a very small amount of light back into your eyes, possibly skewing vision. AR/AG coatings help to prevent this anomaly.
