Abstract
A flat panel display is disclosed. In one embodiment, display normal light that is parallel to a display normal of the flat panel is provided. Spaced light redirecting prisms receive the display normal light and redirect the display normal light to redirected light, which is non-parallel to the display normal. A flat surface portion is posteriorly coupled to the plurality of spaced light redirecting prisms such that the flat surface portion spans the spaces between the plurality of spaced light redirecting prisms. The flat surface portion receives the display normal light from the light guide and receives the redirected light from the plurality of spaced light redirecting prisms and propagates both to a display.
