摘要： A method and device for driving an electro-optical light shutter array including a plurality of shutter elements each having an electro-optical effect to polarize an incident light by setting up an electric field. The device includes a plurality of individual electrodes provided on the respective shutter elements and a common electrode provided on the respective shutter elements electrically in common. A square pulse is applied to the arbitrary individual electrode while a triangular pulse is applied to the common electrode to set up an electric field of which an intensity continuously varies within one driving period. Moreover, an alternating electric field may be set up in the electro-optical light shutter array in a recovery period. In this case, a first light amount when the positive electric field is set up and a second light amount when the negative electric field is set up are detected. A recovery operation is carried out until the first and second light amounts become substantially equal with each other.
