A display device includes multiple pixels, a gate driver and a data driver. Each pixel includes a transistor and a pixel capacitor electrically coupled to the transistor. The gate driver is configured to turn on the transistor of a first pixel for one time during a first turn-on period of multiple turn-on cycles of a frame cycle of a frame displayed by the display device. The data driver is configured to charge the pixel capacitor of the first pixel via the transistor of the first pixel to a first over-charge voltage and a data voltage during an over-charge period and a recovery period of the first turn-on period. The first over-charge voltage is different from the data voltage. A method for driving the display device is also provided.
