Abstract:
1. An electronic device comprising: a planar display; and a touch panel that overlaps the display and that can detect two dimensional coordinates of an indicator on a surface of the display and a vertical distance from the indicator, wherein the touch panel has the detection zone has the first zone, in which the vertical distance is a specific value between the first value and the second value, narrows as the specific value increases from the second value toward the first value, at least the two dimensional coordinates of the indicator are taken as valid coordinates when the indicator directly enters the first zone from the non-detection zone where the vertical distance is greater than the first value, and at least the two dimensional coordinates of the indicator are taken as valid coordinates when the indicator then enters the second zone from the first zone, and at least the two dimensional coordinates of the indicator are taken as invalid coordinates when the indicator directly enters the second zone from the non-detection zone where the vertical distance is greater than the first value, at least the two dimensional coordinates of the indicator are taken as valid coordinates when the indicator then enters the first zone from the second zone, and at least the two dimensional coordinates of the indicator are taken as valid coordinates when the indicator then enters the second zone from the first zone.
