Abstract:
A flip-flop circuit is provided. A driver circuit is provided. The flip-flop circuit includes first to fifth input terminals and first to third output terminals, the first input terminal is supplied with a first trigger signal, the second input terminal is supplied with a second trigger signal, the third input terminal is supplied with a batch selection signal, the fourth input terminal is supplied with a first pulse width modulation signal, and the fifth input terminal is supplied with a second pulse width modulation signal. The first output terminal supplies a first selection signal in response to the first pulse width modulation signal in a period from supply of the first trigger signal to supply of the second trigger signal, the first output terminal supplies the first selection signal in a period during which the batch selection signal is supplied, the second output terminal supplies a second selection signal in response to the second pulse width modulation signal in the period from the supply of the first trigger signal to the supply of the second trigger signal, and the third output terminal supplies a third trigger signal.
