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.
