Abstract
An electronic device with a touch sensor comprises: a touch screen including touch sensors defined by Tx lines and Rx lines; a touch sensing circuit that supplies a drive signal to the Tx lines and senses a voltage change in the touch sensors to output sensing data; and a noise filtering unit that profiles the type of noise in the sensing data and compensates the sensing data so that the sensing data is near the maximum threshold or the minimum threshold, which is calculated based on a average value of the previous frame, or within the range between the maximum and minimum thresholds.
