Abstract
Disclosed herein is a display film stack for a backlight display system. In one embodiment, the display system comprises: a light source, a first film comprising a first surface texture layer that is formed of a first material of a first refractive index, and a second film comprising a second surface texture layer that is formed of a second material of a second refractive index. The second film is disposed between the light source and the first film. The second refractive index is greater than the first refractive index. The light source is disposed in optical communication with the first film and the second film. The first surface texture layer and the second surface texture layer comprise unit structures independently selected from the group consisting of hemispherical structures, partial hemispherical structures, ellipsoidal structures, immersed spherical beads, ellipsoidal beads, 'bell-shape' bump and complex lens shape structures.
