摘要:
A display driver includes a line latch circuit; a first D/A conversion circuit; a second D/A conversion circuit; a first amplifier circuit configured to initialize charges of a capacitor of a first switched capacitor circuit in a first initialization period and output a data voltage in a first output period; a second amplifier circuit configured to initialize charges of a capacitor of a second switched capacitor circuit in a second initialization period and output a data voltage in a second output period; and a control circuit. The control circuit is configured to end the second initialization period of the second amplifier circuit before display data is latched by the line latch circuit at a latch timing and an output of the first amplifier circuit changes.
