  • Patent number: 9465492
    Abstract: A touch panel system prevents an incorrect operation caused by an unintended contact of an object with a touch panel while suppressing a decline in sensitivity of detection of presence or absence of a touch on the touch panel. The touch panel system includes a touch invalidating section which, in a case where a specific point of a touch panel is continuously touched for a predetermined period of time, invalidates an instruction that is given, in accordance with the touch, to an electronic device including the touch panel.
