Title: Innovations by Chih-Chung Chen
Introduction
Chih-Chung Chen is a notable inventor based in Taichung County, Taiwan. He has made significant contributions to the field of touch input technology, holding a total of 6 patents. His work focuses on enhancing the functionality and efficiency of touch panels and input devices.
Latest Patents
One of his latest patents is a touch input device that includes a substrate, multiple sensible conductive layers, and several first switch units. The substrate is designed with an upper surface where the conductive layers are arranged in columns and rows. The first switch units are configured on the substrate and are electrically connected to the conductive layers, allowing for electrical conduction between the same columns and rows of the layers. Another significant patent is a capacitance sensing circuit for touch panels. This circuit comprises an analog capacitance-detecting circuit, a PWM-to-digital circuit, and a self-calibration circuit. The analog circuit detects the capacitance of the touch panel based on a charging current and converts it into a PWM control signal. The PWM-to-digital circuit then transforms this signal into a sensing count value based on a clock signal, while the self-calibration circuit adjusts the charging current or clock frequency to match the predetermined detecting range.
