Abstract
A driver includes a power supply circuit including a voltage boosting circuit that generates a boosted voltage by performing a voltage boosting operation, and a driving circuit that receives a power supply from the power supply circuit, and samples a driving voltage to drive a display panel. The voltage boosting circuit has a voltage boosting unit having a voltage boosting transistor, and a voltage boosting control circuit that outputs a voltage boosting clock signal to the voltage boosting unit. The voltage boosting control circuit stops the voltage boosting clock signal in a first period that includes a timing of an end of a sampling period of the driving circuit.
