Claim:
1. An electronic device comprising: a planar display; and a touch panel overlapping the planar display, and configured to detect proximity of an indicator to a surface of the planar display and at least two dimensional coordinates of the indicator on the surface of the planar display, wherein the touch panel has a first zone that includes at least a first vertical distance from the surface of the planar display, the first vertical distance being less than a first value and greater than a second value which is smaller than the first value, and includes a center of the planer display with respect to the two dimensional coordinates, the touch panel has a second zone that includes at least the first vertical distance from the surface of the planar display, and is located outside the first zone with respect to the two dimensional coordinates, and the touch panel has a third zone that includes at least a second vertical distance from the surface of the planar display, the second vertical distance being greater than the first value, wherein when the indicator directly enters the second zone from the third zone, at least the two dimensional coordinates of the indicator are taken as invalid coordinates, when the indicator directly enters the first zone from the third zone, at least the two dimensional coordinates of the indicator are taken as valid coordinates, and when the indicator directly enters the second zone from the first zone, at least the two dimensional coordinates of the indicator are taken as valid coordinates.
