OPTICALLY ADDRESSED GREY SCALE ELECTRIC CHARGE-ACCUMULATING SPATIAL LIGHT MODULATOR Russian patent published in 2012 - IPC G02F1/135 

FIELD: physics.

SUBSTANCE: device includes an electrooptic layer, a back plane, a light source which is in optical connection with the electrooptic layer and a controller connected to memory. The back plane defines the pixel location in the electrooptical layer. The controller is meant, during a frame, to sequentially and discontinuously apply a plurality of selected write cell voltages at a pixel location of an optical write valve. After the pixel location achieves an optically stable state for each of the applied write cell voltages, the controller modulates the light source in accordance with the time at which the selected write cell voltages are applied.

EFFECT: ensuring monotony of the grey scale characteristic of the light.
