Abstract: A display panel driving apparatus includes a data driver, a gate driver, an extra resistance part through which a constant current passes, and a circuit configured to generate a first gamma voltage, and output a first extra gamma voltage indirectly to the data driver through the extra resistance part. The data driver is configured to generate a data signal based on the first gamma voltage and output the data signal to a data line of a display panel. The gate driver is configured to output a gate signal to a gate line of the display panel.

Abstract: In a display device, each of pixels includes a light emitting element and a pixel circuit which is connected to the light emitting element at a first node and drives the light emitting element in response to a corresponding driving scan signal among driving scan signals during a display period. The pixel circuit is connected to a corresponding readout line among readout lines at a second node. The sensing circuit senses a potential of the first node through the corresponding readout line during a blank period, and each of frames includes the display period and the blank period. At least two driving scan signals among the driving scan signals respectively include a plurality of rewriting periods, each of which is activated during the blank period corresponding thereto, and the rewriting periods of the driving scan signals have different durations from each other.
