Abstract
A display assembly includes a light pipe having re-directing channels defined therein. When a light source is provided in a compartment of the light pipe, light admitted from the light source to the light pipe emits from a front face of the light pipe. In addition, light emitted from reflective surfaces spaced apart from external surfaces of the light pipe combine with light emitted through the front face to provide glow regions of light resulting in symmetric uniform illumination of the display.
