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.
Claims9
A position detecting method for a touchscreen panel on which a conductive film divided into a plurality of conductive regions is formed, the position detecting method comprising:
- conducting a first sequential scanning, the first sequential scanning sequentially scanning the conductive regions one by one to determine whether the touchscreen panel is contacted with respect to each of the conductive regions;
- detecting a first contacted position on the touchscreen panel at which the touchscreen panel is contacted within a first conductive region among the conductive regions during the first sequential scanning;
- conducting a second sequential scanning after conducting the first sequential scanning, the second sequential scanning sequentially scanning the conductive regions one by one to determine whether the touchscreen panel is contacted with respect to each of the conductive regions;
- detecting a second contacted position on the touchscreen panel at which the touchscreen panel is contacted within a second conductive region among the conductive regions during the second sequential scanning;
- determining whether the detected second contacted position is within or outside a predetermined region around the detected first contacted position;
- and
- determining that a contact with the touchscreen panel has moved on the touchscreen panel from the detected first contacted position to the detected second contacted position in response to determining that the detected second contacted position is within the predetermined region.
