Abstract
Assemblies and techniques are provided for light guides integrated into display devices having front light sources. In one aspect, a light guide can include one or more reflective coatings that are applied or otherwise integrated onto one or more internal surfaces of the light guide. Application of at least one reflective coating can modify the luminance and/or chromaticity of the light guide. The one or more coatings can comprise one or more applied layers of paint, such as a layer of a glossy colored paint and/or a layer of a chrome paints.
