Touch screen contact object discrimination method and capacitance pen signal transmission method thereof

The invention discloses a touch screen contact object discrimination method and a capacitance pen signal transmission method thereof. The touch screen contact object discrimination method comprises the following steps of confirming a peak value and a valley value of a capacitance value image according to the capacitance value image of the mutual capacitance of a mutual capacitance array when a finger is in contact with a touch screen; adjusting the strength of a feedback driving signal of an active capacitance pen to enable a peak value of a capacitance value image generated when the active capacitance pen is in contact with the touch screen to be higher than that of the capacitance value image generated by the finger or a valley value of the capacitance value image generated when the active capacitance pen is in contact with the touch screen to be lower than that of the capacitance value image generated by the finger or adjusting the active capacitance pen to enable the active capacitance pen to feed back a
