Abstract:
An optical modulator integrated circuit structure, comprising:a light transmissive sheet including at least one light transmissive electrode wherein all of said at least one light transmissive electrode are connected together in common in order to output a common voltage at the same time; an optical modulator including a layer of an electro-optic material having a means for providing both a positive and negative voltage across said layer in a frame period and a means for providing a plurality of voltage pulses to said commonly connected at least one transmissive electrode of said light transmissive sheet in a first given time period; an integrated circuit including electrodes which cooperate with selected regions of said layer, wherein said integrated circuit electrodes are addressed with data according to an addressing sequence, wherein said sequence is repeated in successive time periods and wherein said integrated circuit includes a first plurality of row conductors each coupled to a first subset of said electrodes and a second plurality of column conductors each coupled to a second subset of said electrodes, said integrated circuit further including means to provide different patterns of voltage pulses during a second given time period to different ones of said first plurality of row conductors and said second plurality of column conductors wherein the means to provide different patterns of voltage pulses include a row decoder and a column decoder wherein said row and column decoders are coupled to a respective one of said first plurality of row conductors and said second plurality of column conductors; and wherein said layer of electro-optic material is provided between said integrated circuit and said light transmissive sheet thereby enabling line by line addressing.
