Display Device Having Touch Panel

A method for operating a touch integrated display device, the method comprising:

• supplying a touch drive signal to a plurality of touch electrodes during a touch sensing period;
• receiving touch sensing signals from the plurality of touch electrodes indicating whether or not a touch occurs in a display area of a touch panel during the touch sensing period;
• generating pulses during a display period by switching between outputting an off-voltage from an off-voltage supply line and outputting an on-voltage from an on-voltage supply line,
• supplying a first auxiliary drive signal to the off-voltage supply line during the touch sensing period;
• supplying a second auxiliary drive signal to a first auxiliary line and a second auxiliary line during the touch sensing period, the first auxiliary drive signal and the second auxiliary drive signal each mimicking the touch drive signal, wherein the first auxiliary line is adjacent to the off-voltage supply line on a first side of the off-voltage supply line, the second auxiliary line is adjacent to the off-voltage supply line on a second side of the off-voltage supply line opposite the first side.

A touch sensitive display device, comprising:

• a touch panel having a plurality of touch electrodes in a display area of the touch display device;
• a touch sensing circuit to supply a touch drive signal to the plurality of touch electrodes during a touch sensing period and to detect if the touch occurred based on touch sensing signals from the touch electrodes;
• a gate driver to supply gate pulses to gate lines of the touch panel during a display period to activate respective rows of pixels to receive pixel data, the gate driver to supply the gate pulses by switching between driving a gate-off voltage from a gate-off voltage supply line onto the gate lines and driving a gate-on voltage from a gate-on voltage supply line onto the gate lines, the gate driver further to supply a gate line auxiliary drive signal from the gate-off voltage supply line onto the gate lines during the touch sensing period, the gate line auxiliary drive signal mimicking the touch drive signal;
• a first auxiliary line adjacent to the gate-off voltage supply line on a first side of the gate-off voltage supply line and a second auxiliary line adjacent to the gate-off voltage supply line on a second side of the gate-off voltage supply line opposite the first side, the first and second auxiliary lines to supply a supplemental auxiliary drive signal during the touch sensing period, the supplemental auxiliary drive signal mimicking the touch drive signal.
