Abstract
A display apparatus includes a display panel including a display area including a plurality of gate lines, a plurality of data lines, and a plurality of touch sensors, a gate driving circuit dividing the display area into a plurality of horizontal blocks and driving gate lines of a horizontal block by units of horizontal blocks at every display period in one frame, and a touch driving circuit sensing a touch through touch sensors of the horizontal block by units of horizontal blocks at every touch sensing period in the one frame.
Claims20
A display apparatus comprising:
- a display panel having a display area including a plurality of gate lines, a plurality of data lines, and a plurality of touch sensors;
- a gate driving circuit dividing the display area into a plurality of horizontal blocks and driving gate lines of a horizontal block by a horizontal block unit during every display period in one frame;
- and
- a touch driving circuit sensing a touch through touch sensors of the horizontal block by the horizontal block unit during every touch sensing period in the one frame,
- wherein the gate driving circuit includes:
- a plurality of driving stage groups, each driving stage group including a plurality of driving stages supplying a scan pulse to gate lines included in a corresponding horizontal block during every display period;
- and
- a plurality of holding stage groups, each holding stage group including at least one holding stage outputting a carry signal to a rear driving stage group, the plurality of holding stage groups disposed between the plurality of driving stage groups, and
- the at least one holding stage charges a holding voltage into a holding capacitor in response to an output signal supplied from a front driving stage group and outputs the carry signal to the rear driving stage group, based on the holding voltage charged into the holding capacitor.
A display apparatus including a display panel having a display area where a plurality of gate lines, a plurality of data lines, and a plurality of touch sensors are disposed, comprising;
- a gate driving circuit including a driving stage group that has a plurality of driving stages supplying a scan pulse to gate lines a corresponding horizontal block during every display period and a holding stage group that has at least one holding stage outputting a carry signal to a rear driving stage group,
- wherein the gate driving circuit divides the display area into a plurality of horizontal blocks and drives gate lines of a horizontal block by a horizontal block unit during every display period in one frame.
