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.

Abstract: A gate driver, a data driver, and a display apparatus including the gate driver and the data driver, may enable a resolution of each region of a display panel to be changed. The gate driver may include a gate resolution control signal output device outputting gate resolution control signals; a gate pulse generating device generating gate pulses to be output to gate lines; and a gate line selection device selecting gate lines, to which the gate pulses output from the gate pulse generating device are to be transferred, on the basis of the gate resolution control signals. The gate pulse generating device includes gate stages generating the gate pulses. The gate line selection device includes gate serial switches; and gate parallel switches. The gate serial switches respectively connect the gate stages to the gate lines, and each of the gate parallel switches connects two adjacent gate lines.
