ABSTRACT:
The invention features a photoconductively addressed display and a method of photoconductive addressing in a display. The method includes providing 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 is provided adjacent to one side of the electro-optic imaging layer. The column electrode layer includes 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 is provided. An elongate portion of the photoconductive layer is illuminated in the X direction while scanning the illumination in the Y direction to translate a location of the illuminated elongate portion. At least one image element of the array of image elements is addressed 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.
