Abstract
A display driving circuit includes a control logic, a source amplifier, and first and second switching elements. The source amplifier includes a first input terminal, a second input terminal, and an output terminal, and amplifies a pixel voltage for displaying an image on a display panel and provides the amplified pixel voltage to a pixel through a data line. The first switching element is connected between the first input terminal and the output terminal, and the second switching element is connected between the first input terminal and the sensing line. The control logic controls the first switching element and the second switching element such that the source amplifier compares a sample voltage that is input to the first input terminal through a sensing line with a comparison voltage input to the second input terminal and outputs comparison data based on the comparison.
