Title: Innovations by Guan-Jung Luo

Introduction

Guan-Jung Luo is a notable inventor based in Taichung, Taiwan. He has made significant contributions to the field of touch panel technology, holding two patents that showcase his innovative approach to device functionality.

Latest Patents

One of his latest patents is a "Touch Panel Driving Apparatus." This invention generates a differential signal corresponding to the detection result of a touch panel. The apparatus includes a driving circuit, a first integrating sampling circuit, and a second integrating sampling circuit. The first integrating sampling circuit generates a first end signal of the differential signal, while the second integrating sampling circuit generates a second end signal. When a touch event does not occur, the levels of both end signals remain within a common mode signal range. However, when a touch event occurs, the first integrating sampling circuit pulls up the level of the first end signal, while the second integrating sampling circuit pulls down the level of the second end signal, effectively distinguishing the touch event.

Another significant patent is the "Driving Device and Device Method." This invention provides a driving device for a sensing device that has multiple driving and sensing electrodes. The driving device includes a signal processing circuit and a readout circuit. The signal processing circuit generates a plurality of driving signals to drive the sensing device by selecting Walsh codes from a Walsh matrix. The readout circuit then generates sensing signals, which are demodulated by the signal processing circuit, enhancing the efficiency of the sensing device.
