<p>The present invention provides an electronic device having a touch sensor and a driving method thereof. The present invention includes: a touch screen having touch sensors defined by Tx lines and Rx lines; a touch sensing circuit which supplies a driving signal to the Tx lines and outputs sensing data by sensing the voltage variation of the touch sensors through the Rx lines; and a noise filtering unit which profiles the shape of a noise for the sensing data and compensates the sensing data in order that the sensing data is close to or within a range of a maximum critical value and a minimum critical value calculated based on the previous frame value.</p> |
