1. A bezel comprising:
- a plurality of bezel apertures extending through the bezel; and
,an integrated decorative film comprising;
a first side having a half-mirrored surface that allows emitted light to pass through the bezel in a single direction only; and
,a second side having a non-uniform diffusion pattern that is dispersed across the second side as a function of distance from a light source positioned to irradiate light on the second side that allows a light irradiated onto the second side to pass through the decorative film and be regulated and emitted uniformly across the bezel.

Abstract
A front panel display assembly may have an integrated decorative film having first and second sides. The first side may have a half-mirrored surface that allows the passage of light in only a single direction and the second side may have a non-uniform diffusion pattern that extends across it. The non-uniform diffusion pattern may regulate and diffuse light irradiated onto the second side to pass through the integrated decorative film and to be regulated and emitted uniformly across the front panel display assembly.
