A scanning method of a touch panel is provided. The touch panel has a horizontal channel group including a plurality of horizontal channels and a vertical channel group including a plurality of vertical channels. According to the scanning method, N channels may be scanned simultaneously, wherein the N channels are selected from the horizontal channel group or the vertical channel group, the N channels are not adjacent to each other, N is a positive integer, and N is less than a channel amount of the selected channel group. Thereby, the scanning speed and the sensing accuracy of the touch panel using the scanning method are enhanced.
