Abstract
An electro-optic display comprising, in order: a light-transmissive layer of conductive material; a layer of bistable electro-optic medium; a layer of light-shielding material; a plurality of pixel electrodes; a layer of photoconductive material; and one or more light emitters. In one exemplary embodiment, the layer of photoconductive material is adapted to bridge a gap between an address line and at least one of the pixel electrodes when the photoconductive material is in a low impedance state. In another, non-exclusive embodiment, the electro-optic display further comprises a second electrode layer between the layer of photoconductive material and the one or more light emitters and a driver adapted to apply voltage between the light-transmissive layer of conductive material and the second electrode layer.
