Abstract
A capacitive touch panel and operating and fabrication methods thereof. The capacitive touch panel has a plurality of transmitter electrodes and a plurality of receiver electrodes. An electric field is formed by the receiver electrodes and the powered one of the transmitter electrodes. The changes, caused by the touch of a user, in the electric field are used in touch recognition. The receiver electrodes are all in a fork shape. For one receiver electrode, the teeth are spaced in a first distance. Note that adjacent teeth from different and adjacent electrodes are spaced apart by another distance. The second distance is greater than the first distance.
