A touch panel and a control method thereof. The control method is applied to a touch panel to receive controls from an active stylus. The control method comprises using a demodulation frequency to demodulate a writing signal received from the active stylus; determining whether a demodulated writing signal is abnormal or not; and in response to determining the demodulated writing signal to be abnormal, adjusting the demodulation frequency to increase an energy of the demodulated writing signal.
