Title: Tsz-Hsuan Chao: Innovator in Capacitive Touch Technology

Introduction

Tsz-Hsuan Chao is a notable inventor based in Guishan, Taiwan. He has made significant contributions to the field of capacitive touch technology, holding a total of 3 patents. His innovative approaches have enhanced the functionality and efficiency of touch devices.

Latest Patents

One of Tsz-Hsuan Chao's latest patents is a clustered scan method of a capacitive touch device. This method involves dividing n drive lines of the capacitive touch device into multiple clusters, each containing the same number of drive lines. The clusters are driven sequentially using a clustered scan procedure. In this procedure, the drive lines of the current cluster are activated for a number of times equal to the number of drive lines in each cluster. If a bordering drive line is present, a bordering clustered scan procedure is executed, which includes driving the bordering line along with some lines from previous clusters.

Another patent by Chao also focuses on a clustered scan method of a capacitive touch device. This method provides driving signals to multiple driving lines in a single driving cycle, including the (i-j) drive line to the (i+k) drive line. In the subsequent driving cycle, signals are provided to some of the previously driven lines, ensuring that the sum of the driving signals in each cycle is greater than zero. This innovative approach improves the signal-to-noise ratio of the touch device and mitigates the adverse effects caused by common ground interactions between the measuring system and the human body, effectively addressing multi-finger positioning issues.
