Abstract
A touch sensing system is discussed. The touch sensing system includes sensor signal lines connected to segment electrodes, sensor enable lines to which a sensor enable pulse is applied, sensor thin film transistors (TFTs) which are turned on in response to the sensor enable pulse and supply a sensing pulse from the sensor signal lines to the segment electrodes, and a touch sensing circuit which applies the sensor enable pulse to the sensor enable lines, simultaneously turns on the two or more sensor TFTs, and applies the sensing pulse to the sensor signal lines.
