Capacitive touch panel input device with improved signal-to-noise detection and input detection method thereof
Abstract:
A touch panel input device and an input detection method thereof are provided. A driving signal is controlled to include a plurality of time intervals in which the driving signal is applied to at least one of at least two driving signal electrodes simultaneously driven, and in which the driving signal is not applied to at least one of at least two driving signal electrodes simultaneously driven. A driving signal supplier causes that a combination of the driving signal electrode to which the driving signal is applied in one of the plurality of time intervals and the driving signal electrode to which the driving signal is not applied in the one of the plurality of time intervals is different from a combination of the driving signal electrode to which the driving signal is applied in the other of the plurality of time intervals and the driving signal electrode to which the driving signal is not applied in the other of the plurality of time intervals. At least one among the driving signals which are simultaneously applied to the driving signal electrode has a phase difference from the other driving signals.
