ABSTRACT:
A method of fine intermediate gradation display by an electro-optical device, with little difference in devices is disclosed. In case of driving each picture element of an active matrix electro-optical device, a visual intermediate gradation display can be carried out by using a modified transfer gate complementary field effect device, in a structure where one of input/output terminal thereof is connected with a picture element electrode, by applying a bipolar pulse to its control electrode in a cycle and by applying voltage to the other input/output terminal, or by cutting voltage at the same time, and whereby digitally controlling duration of voltage applied to the picture element.
