Abstract
A display driving circuit includes an operational amplifier configured to, in a first phase of a test period, charge a source line of a display panel based on a first voltage received through a first input terminal, and in a second phase of the test period, output a comparison result signal by comparing a second voltage received through the first input terminal with a source line voltage received through a second input terminal; a discharge circuit configured to discharge the source line in the second phase; switches configured to, in the first phase, connect an output terminal of the operational amplifier to the source line, and in the second phase, connect the discharge circuit to the source line and the second input terminal of the operational amplifier; and a control logic configured to control a bias current of the operational amplifier based on the comparison result signal.
