Display device and method of driving the same

A display device comprising:

• a plurality of gate lines arranged in a first direction;
• a plurality of data lines arranged in a second direction, perpendicular to the first direction;
• a plurality of pixels corresponding to the gate lines and the data lines;
• and
• a plurality of touch groups including a plurality of self-capacitance electrodes and a plurality of touch lines that receive a common voltage during a displaying period,
• wherein, the self-capacitance electrodes are connected to the respective touch lines in a one-to-one correspondence relationship, and configured to receive touch driving signals through the touch lines and configured to transfer touch sensing signals through the touch lines during a touch sensing period which is followed by the displaying period, and
• wherein, each touch group is arranged in the first direction such that at least one gate line extends along each touch group and the plurality of touch groups are arranged in the second direction such that at least one data line extends along certain self-capacitance electrodes in every touch group.
