Abstract:
A display device includes a display unit having pixels, a touch sensing unit including 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 touch electrodes. The touch driver supplies a first touch driving signal having a first phase to one or more first touch electrodes, and supplies a second touch driving signal having a second phase opposite to the first phase to one or more second touch electrodes, at least a part of which is disposed across a specific point from the first touch electrodes. The touch driver receives a first touch sensing signal having the first phase from at least one of the first touch electrodes, and receives a second touch sensing signal having the second phase from at least one of the second touch electrodes.
