Abstract: A touch panel includes a display module, a touch sensor and a signal processing unit. The display module includes a timing control circuit and a data driving circuit, wherein the timing control circuit outputs latch signals to the data driving circuit, and the display module generates surface noises. The touch sensor is disposed above the display module and outputs abnormal signals, wherein the abnormal signals include a sensing signal and the surface noises. The signal processing unit is electrically connected to the touch sensor and receives the abnormal signals, wherein the signal processing unit calculates a predetermined time by utilizing a rising edge or a falling edge of the latch signal, suspensively processes the sensing signal during the predetermined time, and then continuously processes the sensing signals beyond the predetermined times so as to keep away from each period of the surface noises.
