Abstract
The present invention discloses a capacitive touch panel, which comprises: an insulation substrate; an electrically-conductive layer, installed on the insulation substrate; and multiple electrically-conductive segments, installed on the perimeter of the electrically-conductive layer. The present invention improves the distribution characteristics of the electric field neighboring the frame of a touch panel via providing at least one chamfer for one end of each electrically-conductive segment. Thereby, the distribution of the electric field lines neighboring the frame can be smooth and uniform. Thus, the accuracy and the usable area of the touch panel are promoted.
