ABSTRACT:
An electro-optical device comprising a display drive system with the display timing related to the unit time t for writing-in a picture element and to the time F for writing-in one picture is disclosed. In the device, a gradated display corresponding to the ratio of the division can be obtained by time-sharing the signal during a write-in of time t without changing the time F.
