Abstract: Disclosed is a display panel. The display panel includes a plurality of first electrodes, a plurality of second electrodes, a plurality of first electrode lines, and a plurality of second electrode lines. The first electrodes are provided in a display part and are used as a common electrode and a touch electrode. The second electrodes are used as the common electrode and each second electrode is disposed adjacent to at least one of the first electrodes. The first electrode lines extend to a non-display part disposed outside the display part and are each connected to a corresponding one of the first electrodes. The second electrode lines extend to the non-display part and are connected to at least two of the second electrodes and supply a common voltage to the second electrodes connected to the second electrode lines.

Abstract: Disclosed are an in-cell touch type touch display device that includes a touch display panel, where a plurality of touch sensors are disposed, and a driving circuit unit. Each of the plurality of touch sensors are disposed to correspond to a plurality of subpixels, and each of the plurality of touch sensors may include one or more touch switches. The one or more touch switches disposed in each of the plurality of touch sensors divisionally drive the plurality of touch sensors by 1/n (where n is a natural number equal to or more than two).

Abstract: Disclosed are a touch driving device, a driving method thereof, and a display device including the same, which reduce power consumption. A touch driving device comprises a first circuit configured to generate a touch driving signal including a plurality of pulses with varying amplitudes or varying periods, responsive to detection of presence or absence of a touch on the touch sensitive display panel during a touch sensing period, and a second circuit configured to apply the touch driving signal to a touch electrode of the touch sensitive display panel during the touch sensing period.
