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 comprises
a detection zone that covers at least a vertical distance which is less than a first value and greater than a second value which is smaller than the first value and where the two dimensional coordinates and the vertical distance can be detected, anda non-detection zone that covers at least the vertical distance which is greater than the first value and where at least one of the two dimensional coordinates and the vertical distance cannot be detected, the detection zone has
a first zone that covers the vertical distance from the first value to the second value and includes a center of the touch panel with respect to the two dimensional coordinates anda second zone that covers at least a part of the vertical distance from the first value to the second value and is outside the first zone with respect to the two dimensional coordinates, the first zone, in which the vertical distance is a certain value between the first value and the second value, narrows as the certain value becomes large 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. |
