Abstract
An electronic display includes electrically conductive layers. At least one active layer is disposed between adjacent electrically conductive layers. The active layer includes cholesteric liquid crystal material. The display includes a front transparent substrate behind which the electrically conductive layers are disposed. A back component is disposed at a back of the display below the active layer. At least one patterned layer is disposed at at least one of the following locations: on, in or near the front substrate and as an interlayer between the front substrate and the back component. The patterned layer is opaque or semitransparent. Electronic circuitry applies a voltage to the conductive layers that enables at least one of erasing or writing of the active layer. The active layer and the patterned layer cooperate to produce an image on the display.
