Abstract
A uniform bezel display uses off-axis illumination from within a rear cavity to direct light into a backlight that distributes the light to a liquid crystal display panel. A light source, such as plural LEDs interfaced with a circuit board, is disposed on a beveled surface formed in the cavity and aligned to direct light into a reflective surface of the backlight interior. Offset placement of the light source in a cavity of the display housing reduces the footprint of the light source at the side of the housing perimeter so that a uniform width bezel will cover the LCD panel around the housing perimeter.
