ABSTRACT:
Problems such as insufficient brightness, caused by a reduction in duty ratio (the ratio of a light emitting period and a non-light emitting period), are improved upon in accordance with using a novel method of driving and a novel circuit in an electronic device. Signals are written into pixels of a plurality of differing lines during one gate signal line selection period. By arbitrarily setting, to a certain extent, the time from when a signal is input into the pixels of a certain line until the next signal is input to the same pixels, while ensuring the time for writing into the pixels, a sustain (turn on) period can be arbitrarily set and a high duty ratio is realized.
