Abstract
A circuit structure for capacitive touch panel is disclosed herein. The circuit structure for capacitive touch panel includes a plurality of metal leads and a plurality of electrode sensing blocks. Those electrode sensing blocks are isolated to each other and electrically connected to the metal leads. The electrode sensing blocks will output a plurality of capacitive signals in accordance with a plurality of touch positions. According to the electrode pattern structure described above, the impedance of the electrode structure can be decreased and the efficiency of the signal transmission can be improved and the sensibility of the touch panel can be increased.
