Patent ID: 6975296

Claim:
A method for driving an electro-optical device having a plurality of pixels, each of which includes a signal line and at least one switching element, said method comprising the step of: applying pulses to said signal line at intervals during one frame, wherein said intervals are T 1 between the i-th pulse and the (i+1)-th pulse, 2 / T 1 between the (i+1)-th pulse and the (i+2)-th pulse, and 2T 1 between the (i+2)-th pulse and the (i+3)-th pulse, where / is a natural number and T 1 is a constant period, wherein said switching element comprises: a crystalline semiconductor film comprising silicon over a substrate having an insulating surface, and at least one gate electrode adjacent to said crystalline semiconductor film with a gate insulating film interposed therebetween.
