Abstract

A display driving circuit includes a gamma generator configured to output, to nodes, gamma voltages having different voltage levels, and a selector configured to select one of the nodes to which the gamma voltages are output, and output a voltage of the selected one of the nodes. The display driving circuit further includes a voltage regulator configured to selectively input a first current to the selected one of the nodes and output a second current from the selected one of the nodes, based on the voltage of the selected one of the nodes, to adjust a voltage level of the voltage of the selected one of the nodes to a voltage level of a respective one of the gamma voltages that is output to the selected one of the nodes.
