ELECTRONIC DEVICE AND COORDINATE DETECTING METHOD

摘要

Disclosed is an electronic device including: a display section that displays information; an electrostatic-capacitance touch panel layer that allows visible light corresponding to display contents of the display section to pass through the touch panel layer and that determines a pair of two-dimensional coordinates indicated by an indicator having conductivity; glass that protects the touch panel layer and that allows visible light corresponding to display contents of the display section to pass through the glass; a depression sensor that detects deformation of the glass; and a control section that validates a pair of two-dimensional coordinates when a plurality of pairs of two-dimensional coordinates are determined by the touch panel layer and when deformation is detected by the depression sensor, the pair of two-dimensional coordinates being determined last among the plurality of pairs of two-dimensional coordinates.

1. An electronic device comprising:
a housing; a display that is disposed inside the housing and that displays predetermined information; an electrostatic-capacitance touch panel that allows visible light corresponding to display contents of the display section to pass through the electrostatic-capacitance touch panel; a transparent member that protects the touch panel and that allows the visible light corresponding to the display contents of the display to pass through the transparent member; and a depression detector that detects deformation of the transparent member, wherein the touch panel is configured to detect a pair of two-dimensional coordinates indicated by an indicator having predetermined conductivity and spaced from the touch panel section at a predetermined distance, wherein when the touch panel detects a plurality of the pairs of two-dimensional coordinates and when the depression detector detects a predetermined amount of deformation: at least one pair of two-dimensional coordinates detected during a predetermined time period towards past based on a time point when the deformation is detected is validated; and a pair of two-dimensional coordinates detected before the predetermined time period based on the time point when the deformation is detected is not validated.
