Abstract: A linear compensation method for touch control systems aims to provide an accurate correction for the depressing electric field that generates signal sources in a touch control system. Through a voltage detection and compensation approach, and after the touch control system has been shipped from the plant with correction done for a rated duty voltage or set duty voltage, and is installed on an operation environment and receives an actual duty voltage, the linear compensation method of the invention updates the linear compensation data according to the voltage variation between the actual duty voltage and the rated or set duty voltage thereby to maintain accurate depressing electric field at the duty voltage for the touch control system.
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.
