Abstract
An LCD/light wedge module used in electronic equipment includes an LCD unit engaged in a central opening, which is sealed to prevent dust from entering. The light wedge module is constructed of light conducting material that is formed to direct light off a back surface and through the LCD unit to a front viewing surface to prevent hot spots.
