Abstract: A position detecting method for a touchscreen panel includes the steps of (a) determining the presence or absence of contact with the touchscreen panel on a conductive film divided into multiple conductive regions; (b) measuring a time after the detection of the absence of the contact and determining whether the measured time is less than a predetermined time if step (a) determines the absence of the contact; and (c) determining the continuance of the contact if the measured time is less than the predetermined time.

Abstract: A touch panel device includes: a first resistance film and a second resistance film each of which includes an electrode; a switch connected to the electrode; a controller that controls operation of the switch; and a detector that, when a voltage is applied to a resistance film of a voltage applied side among the first resistance film and the second resistance film, detects presence or absence of touch and a position of the touch based on a voltage detected from the electrode on a resistance film of a voltage detection side among the first resistance film and the second resistance film; wherein before detection operation by the detector, the controller controls the operation of the switch connected to the electrode on the resistance film of the voltage detection side so that the electrode on the resistance film of the voltage detection side is grounded.
