    Abstract: An input detection system includes a detection device including a plurality of drive electrodes and a plurality of detection electrodes arrayed in a detection region, and a drive electrode scan circuit configured to supply a drive signal to the drive electrodes, and an input device including an LC circuit, a first electrode coupled to one end side of the LC circuit, and a second electrode coupled to the other end side of the LC circuit. The drive electrode scan circuit supplies the drive signal to at least equal to or more than one of the drive electrodes and supplies, to the others of the drive electrodes, an opposite phase signal as a drive signal having an opposite phase to a phase of the drive signal.

    Abstract: An input detection system includes a plurality of electrodes arrayed in a detection region, and an input support device including an LC circuit, a first electrode coupled to the LC circuit and arranged so as to overlap with at least equal to or more than one of the electrodes, and a housing accommodating therein at least the LC circuit. The housing is a conductor, and one end side of the LC circuit is coupled to the housing through a coupling member or a capacitor and another end side of the LC circuit is coupled to the first electrode.
