Patent attributes
A touchpad device includes a capacitive touch pad and a near field communication antenna. The capacitive touch pad includes a plurality of input circuits and a plurality of output circuits. Each input circuit and each output circuit intersect and are arranged substantially perpendicular to each other, thereby forming a chessboard-like circuit. The near field communication antenna includes an antenna structure crosses at least part of the plurality of input circuits and at least part of the plurality of output circuits. The antenna structure is substantially not parallel to any one of the input circuits crossed by the antenna structure, and the near field communication antenna being substantially not parallel to any one of the output circuits crossed by the antenna structure.
