Abstract: In a coordinate detection apparatus, a resistance-film is formed on a substrate made of an insulating material. A common electrode applies a voltage to the resistance-film, the common electrode extending along a plurality of a resistance-film removal areas formed by removing portions of the resistance-film. A voltage application part applies the voltage to the common electrode. The voltage is applied from the voltage application part to the resistance-film through the common electrode to generate a potential distribution in the resistance-film. A coordinate position of a contact position at which the resistance-film is contacted is detected by detecting a potential of the resistance-film at the contact position.

Abstract: A touchscreen panel includes an upper substrate having a first transparent conductor layer provided on a first base layer, and a lower substrate having a second transparent conductor layer provided on a second base layer. The first and second transparent conductor layers oppose each other via a spacer and make contact when the first base layer is pressed. The first transparent conductor layer is segmented into a plurality of conductive regions that are electrically insulated from each other.

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.
