Abstract
In accordance with the present invention, a transparent display, such as an LCD, is provided with back reflector having a plurality of reflecting facets angularly displaced with respect to the plane of the display cell so as to enhance contrast of the display without consumption of additional power while reducing glare. Advantageously the reflecting facets are oriented to concentrate reflection to a viewer of light above the viewer and light coming from over the viewer's shoulder. The result of such concentration is a display having backlit visual characteristics without the consumption of backlighting power. Preferred embodiments are disclosed for vertical and horizontal mounting.
