Claim Text:
1. A driver circuit for driving a touch integrated display device, the driver circuit comprising: a first circuit to supply a touch drive signal to a plurality of touch electrodes during a touch sensing period and to receive touch sensing signals from the plurality of touch electrodes in a display area of a touch panel indicating whether or not a touch occurs during a touch sensing period; and a second circuit to generate 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, the second circuit further to supply a first auxiliary drive signal to the off-voltage supply line during the touch sensing period, and the second circuit further to supply 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 and 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.
