<p>PURPOSE: A touch screen driving device and a method thereof are provided to reduce effect of noise inflowing from a display panel. CONSTITUTION: A Tx driving circuit(32) sequentially supplies a driving pulse to Tx lines and supplies driving pulses having reverse phase with each other to the neighboring Tx lines. An Rx driving circuit(34) samples voltage of a sensor node received through Rx lines coupled to the Tx lines and converts the sampled voltage into digital data. A touch controller(30) controls the Tx driving circuit and the Rx driving circuit, analyzes data due to the final touch with a predetermined touch recognition algorithm and estimates a coordinate of the touch input location.</p> |
