Abstract
The present disclosure relates to a touch panel having a shielding structure and a method of manufacturing the same. The touch panel having a shielding structure comprises a conductive ring disposed on periphery of an upper surface of a substrate, a shielding layer disposed on a lower surface of the substrate, and a plurality of conductive connection points electrically connecting the shielding layer and the conductive ring. By connecting the shielding layer and the conductive ring by the conductive connection points, impedance of the shielding layer is consistent for different distances between the shielding layer and flexible printed circuit, thereby eliminating noise interference from a liquid crystal display or an electronic device under the touch panel, while using the touch panel. Moreover, the manufacturing method of the touch panel with a shielding structure is a simple process, which reduces the manufacturing cost.
