Patent ID: 6900851

Claim:
A photoconductively addressed display comprising: an electro-optic imaging layer that extends in an X direction and a Y direction, and comprises an array of image elements; a column electrode layer adjacent to one side of the electro-optic imaging layer and comprising a plurality of column electrodes that each extend in the Y direction and are spaced from one another in the X direction; a photoconductive layer disposed between the electro-optic imaging layer and the column electrode layer; a light source that illuminates an elongate portion of the photoconductive layer in the X direction while scanning emitted light in the Y direction to translate a location of the illuminated elongate portion; and a voltage source that addresses at least one image element by applying an intermittent voltage to one of the plurality of column electrodes that is adjacent to the at least one image element while the illuminated elongate portion of the photoconductive layer is adjacent to the at least one image element.
