Abstract:
An electromagnetic inductive touch panel includes a first substrate and a touch structure layer disposed on the first substrate. The touch structure layer includes a plurality of first wires; a plurality of second wires insulatedly intersecting with the plurality of first wires; and a plurality of electromagnetic inductive coils disposed respectively at intersections of the first wires with the second wires. Each of electromagnetic inductive coils includes a first sub-coil and a second sub-coil spirally wrapped around each other. The first sub-coil has one end electrically connected with one of the first wires and the other end electrically connected with a common potential; and the second sub-coil has one end electrically connected with one of the second wires and the other end electrically connected with the common potential.
