Abstract
A display device includes at least one touch sensor configured to sense a touch in response to a touch signal, a display panel including the at least one touch sensor and configured to operate in one of a display mode and a touch-sensing mode, a first circuit and a second circuit. The first circuit is configured to supply at least one of a first touch signal and a second touch signal to the at least one touch sensor during the touch-sensing mode, to yield at least one supplied signal, the first touch signal being different from the second touch signal. The second circuit is configured to control signal lines corresponding to the at least one touch sensor to receive a signal corresponding to the at least one supplied signal or to be in an electrically open state.
