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.
