The present specification discloses a gate driver, a display device including the same, and a method of driving the display device. When a gate-on voltage of a Jclock signal differs from a gate-on voltage of the first clock signal, the gate driver applies a compensation gate-on voltage that is a gate-on voltage at a changed voltage level to a gate-on voltage node. The display device includes a sensing unit for sensing a clock signal, and a compensation unit for applying the compensation gate-on voltage to the gate driver from the sensed clock signal. According to the present specification, a gate-source voltage of a transistor disposed on an output unit may be maintained at a previous voltage. In addition, it is possible to prevent driving failures caused by a load received by the clock signal supplied to a stage disposed relatively far away.

Gate driver, display device including the same, and driving method of display device

A display panel can include a plurality of first pixel circuits configured to receive a pixel driving voltage and a reference voltage for displaying an image; and a plurality of second pixel circuits including a power line supplied with the pixel driving voltage and a reference voltage line supplied with the reference voltage, the plurality of second pixel circuits being configured to short-circuit the power line to the reference voltage line for at least some amount of time within a vertical blank period. Also, the plurality of second pixel circuits can maintain uniform luminance of the plurality of first pixel circuits.
