Patent ID: 10664117

Abstract:
A touch panel includes a base layer having a shaded area and a visible area; a first sensing layer having first capacitive sensing columns (FCSCs) and first electromagnetic antenna columns (FEACs), which are insulated; a first auxiliary conductive layer having a circuit pattern substantially identical to the first sensing layer, and the circuit pattern correspondingly electrically connecting to the first sensing layer; a second sensing layer having second capacitive sensing columns (SCSCs) and second electromagnetic antenna columns (SEACs), which are insulated; a second auxiliary conductive layer having a circuit pattern substantially identical to the second sensing layer, and the circuit pattern correspondingly connect to the second sensing layer; and an insulative layer between the first and second sensing layer. The FCSCs are orthogonal to the SCSCs to constitute a diamond-lattice-shaped capacitive sensing unit array, and the FEACs are orthogonal to the SEACs to constitute a diamond-lattice-shaped electromagnetic antenna array.
