Abstract

When a touch sensor is approached or touched by a capacitive pen in a small area, the corresponding approach or touch signal might be slightly less than the threshold originally used for normal detection. By comparing the sum of the corresponding approach or touch signal and some adjacent signals with the threshold, the approach or touch of a small-area object that otherwise would not be detected by the original method can be determined. The capacitive pen can be made of bonded conductive fibers.
