Abstract
A display device including a display panel including pixels, a data driver configured to apply a data voltage to the pixels, a sensing driver configured to receive a sensing voltage from the pixels, a gate driver configured to apply a gate signal to the pixels, and a driving controller configured to control the gate driver, the sensing driver, and the data driver. The sensing driver generates leakage sensing data for current leakage characteristic of the pixels based on the sensing voltage received in a first sensing period, and generates threshold voltage sensing data for a threshold voltage of a driving transistor of the pixels based on the sensing voltage received in a second sensing period.
