Gate driving circuit and display device including the same

A display device comprising:

• a display panel comprising a sub-pixel configured to display a portion of an image, and a touch electrode configured to sense a touch of the display panel;
• and
• a gate driving circuit comprising a plurality of stages configured to supply scan signals to the display panel,
• wherein a stage among the plurality of stages comprises:
• a driving circuit configured to charge an M node based on a selection signal externally supplied to the driving circuit responsive to receiving a carry signal received from another stage from the plurality of stages and charge a Q node with a high voltage responsive to a reset signal and a voltage charged in the M node that corresponds to the selection signal,
• a node controller connected to the driving circuit, the node controller configured to control the Q node and a Qb node responsive to driving of the driving circuit, wherein a level of a voltage at the Qb node is opposite to a level of a voltage at the Q node, and
• an output circuit connected to the node controller, the output circuit configured to output a carry signal and at least one scan signal responsive to the voltage at the Q node and the voltage at the Qb node included in the node controller,
• wherein at least two stages among the plurality of stages simultaneously output scan signals responsive to the selection signal during a touch sensing period during which touch of the touch electrode is sensed, the outputted scan signals generated as an on-voltage during the touch sensing period.

A display device comprising:

• a display panel comprising a plurality of touch electrodes and a plurality of subpixels including a first subpixel and a second subpixel, the plurality of touch electrodes configured to sense a touch of the display panel during a touch sensing period of a frame period, and the plurality of subpixels configured to display an image during a display driving period of the frame period;
• and
• a gate driving circuit comprising a plurality of stages configured to output a plurality of scan signals to the plurality of subpixels, the plurality of stages including a first stage connected to the first subpixel and a second stage connected to the second subpixel,
• wherein during the touch sensing period the first stage is configured to output a first scan signal from the plurality of scan signals to the first subpixel to sense touch of a first location of the display panel and the second stage is configured to output a second scan signal to the second subpixel at a same time that the first stage outputs the scan first signal the first subpixel to sense touch of a second location of the display panel.
