Title: King Ho Cheung: Innovator in Organic Light Emitting Diode Technology

Introduction

King Ho Cheung is a notable inventor based in Hong Kong, CN. He has made significant contributions to the field of organic light emitting diode (OLED) technology, holding 2 patents that showcase his innovative approach to display technology.

Latest Patents

One of his latest patents is for a passive matrix organic light emitting diode display. This PMOLED display features a plurality of lower electrode patterns arranged in parallel along the x-axis and a plurality of transparent electrode patterns arranged in parallel along the y-axis, which are perpendicular to the lower electrode patterns. An organic compound layer is interposed between these electrode patterns. The display output and touch sensing are performed by time-sharing a control period for both the lower and transparent electrode patterns into a display control period and a touch-sensor control period within each display frame time. Additionally, the PMOLED display includes a driving node for communication between the transparent electrode patterns and a display driving circuit, along with a touch-sensing unit that connects the driving node to a touch-sensing circuit. Furthermore, a series of metal electrode patterns are provided between the transparent electrode patterns, with lengths shorter than those of the transparent electrode patterns.

Another significant patent involves a method of sensing illuminance using a passive matrix organic light emitting diode display that includes an illuminance sensor function. This method comprises several steps, including forming a predetermined voltage difference between at least one of the transparent electrode patterns and the lower electrode patterns, measuring the current formed by these patterns, and ultimately measuring the illuminance using the measured current.
