Claim 0:
1. A display device comprising:
a display unit having a plurality of pixels;
a touch sensing unit comprising a plurality of touch electrodes disposed on the display unit; and
a touch driver configured to supply a touch driving signal to the plurality of touch electrodes and receive a touch sensing signal from the plurality of touch electrodes,
wherein the touch driver supplies a first touch driving signal having a first phase to at least one first touch electrodes, and supplies a second touch driving signal having a second phase to at least one second touch electrodes, the at least one first touch electrodes being disposed on one side of a specific point and the at least one second touch electrodes being disposed on the other side of the specific point,
wherein the touch driver receives a first touch sensing signal having the first phase from the at least one first touch electrodes, and receives a second touch sensing signal having the second phase from the at least one second touch electrodes, and
wherein the at least one first touch electrodes receives the first touch driving signal having the first phase during a charging period and supplies first touch sensing signal having the first phase during a discharging period, the at least one second touch electrodes receives the second touch driving signal having the second phase during the charging period and supplies second touch sensing signal having the second phase during the discharging period.
