Abstract
A display device includes a plurality of pixels. A gate line extends in a first direction and is connected to each of the plurality of pixels. A common electrode is disposed above the gate line and extends across the plurality of pixels. A touch sensing unit is disposed above the common electrode and includes a plurality of driving electrodes and a plurality of sensing electrodes. A display driver drives the plurality of pixels. A first fan-out line is connected to the display driver. A touch driver drives the driving electrodes and the sensing electrodes. A second fan-out line is connected to the touch driver. A first switching element selectively connects one of the first fan-out line and the second fan-out line to the gate line.
Claims21
