Claim Text:
1. A method of optically writing to a charge integrating gray-scale optical read light valve comprising: applying a plurality of selected write cell voltages at a pixel location of an optical write light valve during a frame interval; after the pixel location achieves an optically stable state for each of the selected write cell voltages, modulating a write light source to illuminate the pixel location so as to emit from the pixel location write light pulses; directing the write light pulses to a localized portion of an electro-optic layer of a charge integrating gray-scale optical read light valve that integrates the write light pulses continuously during the frame interval; and sequentially repeating the applying, modulating, and directing for a plurality of selected write cell voltages over subsequent frame intervals.
