Title: EngJye Ng: Innovator in Touch Panel Technology

Introduction

EngJye Ng is a prominent inventor based in Singapore, known for his contributions to touch panel technology. With a total of 3 patents, he has made significant advancements in enhancing the accuracy and reliability of touch sensors.

Latest Patents

One of EngJye Ng's latest patents is a self-sensing touch panel. This innovative method utilizes differential self-capacitance measurement to improve the signal-to-noise ratio of sense lines in a touch panel display. As a result, the accuracy of touch sensors is significantly enhanced. The technique involves charge sharing between adjacent sense lines of the touch panel matrix. By performing sequential differential self-capacitance measurements, changes caused by intervening events can be tracked across the entire touch panel matrix.

Another notable patent is the method and apparatus for blocking the accumulation of electrical fast transient (EFT) noise. This invention features a charge sensing circuit that generates a voltage indicative of sensed charge during a sensing period. The generated voltages are accumulated by an accumulator circuit over multiple sensing periods. A noise detection circuit monitors the voltage and generates a detection signal when it falls outside a specified boundary. In response, a control circuit blocks the accumulation of voltages during the sensing period in which the detection signal is generated. An analog-to-digital converter then converts the accumulated output voltage to a digital value at the end of the accumulation time period.
