Title: Chi-An Jen and Touch-Control Technology
Introduction
Chi-An Jen is an inventor based in Zhubei, Taiwan, associated with Mstar Semiconductor, Inc. His patent work concerns touch sensing and control in portable electronic devices.
Latest Patents
The provided information lists one patent for Jen: “Portable Electronic Device and Touch Control Chip and Touch Control Method Thereof.” The invention describes a portable device with a touch-sensing circuit and a conductive layer containing multiple sensing electrodes. The touch-sensing circuit detects a touch point based on changes in capacitance at those electrodes. A resistance-measuring circuit measures resistance in at least part of the conductive layer, and a control circuit uses that measurement to determine whether the touch-sensing circuit should enter a correction mode. Jen is credited with 1 patent.
Career Highlights
Jen’s listed invention addresses touch-control reliability by using resistance measurements to guide correction of the touch-sensing circuit. The provided data associates him with Mstar Semiconductor, Inc.
Collaborations
