TOUCH SENSOR

摘要

A touch panel is disclosed. The touch panel includes driving lines and sensing lines. A node capacitor is formed between a driving line and an adjacent sensing line. The touch panel also includes a driver configured to demodulate a driving signal using a direct sequence spread spectrum method and supply the demodulated driving signal to each of the driving lines, and a sensor electrically connected to the sensing lines, configured to detect a variation in a capacitance of the node capacitors. The sensor demodulates a signal from the sensing line using the direct sequence spread spectrum method.
