Abstract

A data driving circuit includes: a resistor string in which a plurality of resistors are connected in series; and a plurality of data channels connected to a high voltage node, intermediate voltage nodes, and a low voltage node of the resistor string and configured to convert a digital data signal into an analog data voltage. Each of the plurality of data channels includes: a main digital-to-analog converter connected to the high voltage node, the intermediate voltage nodes, and the low voltage node, a multiplier connected to an output terminal of the main digital-to-analog converter, a sub digital-to-analog converter connected to some of the high voltage node, the intermediate voltage nodes, and the low voltage node, and a voltage synthesizer connected to an output terminal of the multiplier and an output terminal of the sub digital-to-analog converter.
