Abstract
A touch panel circuit is disclosed. The touch panel circuit includes a signal transmission path and a ground path. An end of the signal transmission path is provided with a first tip structure protruding outward and having a needlepoint-shape end portion. The ground path is provided with a second tip structure having a needlepoint-shape end portion which is opposite to the needlepoint-shape end portion of the first tip structure. The needlepoint-shape end portion of the first tip structure of the signal transmission path is configured to aggregate electrostatic charges on the signal transmission path, and discharge the aggregated electrostatic charges to the second tip structure of the ground path opposite to the first tip structure.
