Abstract
An apparatus to widen the light dispersion pattern of a light source shining through an overlay window from the viewing side of an electrical computer system. The overlay window is coupled to a panel of the system. The overlay window includes a transparent material, which has a first surface facing the light source and a second surface facing away from the light source to define a viewing side. An opaque material can be disposed on the first surface to partially cover the first surface to form a viewing window. A first diffusing mechanism is disposed on the first surface, and a second diffusing mechanism is disposed on the second surface. In response to the passage of the light output through the viewing window, the light dispersion pattern of the light output from the viewing side of the overlay window has a viewing angle of up to about 180 degrees.
