Abstract
Disclosed is a digital-to-analog conversion circuit in which first and second serial DACs and an amplifier circuit for driving a data line are provided. In a first data period, the first serial DAC converts a first digital signal received in the first data period to a first signal, the second serial DAC holds a signal obtained by converting a digital signal received in a data period one period before the first data period, and the amplifier circuit amplifies and outputs the signal held in the second serial DAC, to the data line. In a second data period following after the first data period, the second serial DAC converts the second digital signal received in a second data period, the first serial DAC holds the first signal converted in the first data period, and an amplifier circuit amplifies and outputs the first signal held in the first serial DAC, to the data line.
