Abstract
A method and a circuit for driving a touch sensor measuring noise and a display device using the same are disclosed. The method of driving the touch sensor includes connecting sensor lines of a plurality of touch sensors to a sensing unit during a noise measurement portion, and driving the sensing unit at previously selected noise measurement frequencies in a state where the sensor lines are connected to the sensing unit or applying a signal of the noise measurement frequencies to the sensor lines to measure a noise of the touch sensors at each of the noise measurement frequencies.
