<p>An embodiment of the present invention relates to a touch screen including: a touch panel which includes driving lines and sensing lines, wherein node capacitors are formed between the driving lines and the neighboring sensing lines; a driving unit which alters a driving signal by using a direct sequence spread spectrum method and provides the altered driving signal to the driving lines individually; and a sensing unit which is electrically connected to the sensing lines and detects the amount of change of capacitance of the node capacitor. The sensing unit directly demodulates the signal received to the sensing lines by using the direct sequence spread spectrum method.</p> |
