Patent ID: 8907919

Claim:
A sensing structure of touch panel, comprising: a substrate, having a first side and a second side opposite to each other; a plurality of first electrode groups, located on said first side of said substrate, each said first electrode group comprising a plurality of first electrodes, and each said first electrode located on said first side and extending towards said second side; a plurality of extended electrode groups, connected to said plurality of first electrode groups, respectively, located on said second side of said substrate, opposite to said plurality of first electrode groups, each said extended electrode group having a plurality of extended electrodes, and each said extended electrode located on said second side and extending towards said first side; a plurality of second electrode groups, located on said substrate, each said second electrode group comprising a plurality of second electrodes, each said second electrode having a first sub-electrode and a second sub-electrode, said first sub-electrode of each said second electrode interleaved with and insulated electrically from each said extended electrode; and a plurality of third electrode groups, located on said substrate, comprising a plurality of third electrodes, each said third electrode having a first sub-electrode and a second sub-electrode, said first sub-electrode of each said third electrode interleaved with and insulated electrically from said second sub-electrode of said second electrode, and said plurality of second sub-electrodes of said third electrode interleaved with and insulated electrically from said first electrode; where one of said first electrodes passes through said second and third electrodes to connect with one of said extended electrodes.
