Abstract
An electronic display includes electrically conductive layers. An active layer is disposed between adjacent electrically conductive layers. The active layer includes cholesteric liquid crystal material. At least one transparent front substrate is disposed adjacent one of the electrically conductive layers near a front of the display. A semitransparent back layer absorbs light that passes through the active layer, reflects grey light or light of a color and is light transmitting. Electronic circuitry applies a voltage to the conductive layers that enables at least one of erasing or writing of the active layer.
