ABSTRACT:
A photosensitive electrophoretic display device is described which provides real time imaging without a reset cycle. This display device operates by the use of interdigitized electrodes at an addressing side of the display on which a photoconductor material having a varying resistance according to light exposure is provided in order to vary the electric field across the electrophoretic suspension. This enables movement of electrophoretic particles according to application of the proper voltages and light exposures.
