Claim:
1. A method for detecting touch points on a touch panel comprising: providing a capacitive type touch panel comprising a conductive layer, a plurality of first electrodes and a plurality of second electrodes, wherein the conductive layer comprises relative low impedance in a direction X and a relative high impedance in a direction Y, and a first side and second side opposite the first side along the direction X; the plurality of first electrodes located on the first side and electrically connected to the conductive layer; and the plurality of second electrodes located on the second side and electrically connected to the conductive layer; obtaining a first signal curve A getting a second signal curve A obtaining a third signal curve B getting a fourth signal curve B determining the number of touch points and obtaining coordinates of the touch points on the touch panel by comparing the first signal curve A
