Abstract: A display device includes a display panel and a scan driver including transistors formed in a non-display area of the display panel. A compensation voltage is supplied to the scan driver through a compensation gate electrode included in at least one transistor of the scan driver. Namely, the at least one transistor includes a gate electrode, to which a signal or a voltage for activating a channel is supplied, and the compensation gate electrode, to which the compensation voltage for recovering a threshold voltage is supplied.

Abstract: A shift register and a display device including the same are provided. The shift register includes a first stage sequentially outputting a gate pulse to first and second gate lines of a pixel array corresponding to a voltage of a first Q node and a second stage sequentially outputting the gate pulse to third and fourth gate lines of the pixel array corresponding to a voltage of a second Q node. The first stage includes a start controller charged with the voltage of the first Q node, a first pull-up transistor increasing a voltage of a first output terminal in response to the voltage of the first Q node and a first gate clock, and a second pull-up transistor increasing a voltage of a second output terminal in response to the voltage of the first Q node and a second gate clock.

Abstract: A scan driver and display device using the same are disclosed. The display device includes display panel, a data driver configured to supply a data signal to the display panel, and a scan driver formed in a non-display area of the display panel, including a shift register composed of a plurality of stages and a level shifter formed outside the display panel, and configured to supply a scan signal to the display panel using the shift register and the level shifter. The scan driver comprises: a sensor circuit unit configured to sense internal and external environmental conditions and generate a compensation circuit control signal on the basis of a sensed result; and a compensation circuit unit generating a compensation signal to compensate outputs of the plurality of stages in response to the compensation circuit control signal.
