Title: **Innovative Contributions of Shu-Huei Cheng in Display Technology**

Introduction

Shu-Huei Cheng, a prominent inventor based in Hsinchu, Taiwan, has made significant strides in the field of display technology. With three patents to his name, Cheng's innovations focus on methods that enhance the quality and production processes of liquid crystal displays (LCDs). His work has greatly influenced the industry, proving the importance of innovative techniques in modern electronics.

Latest Patents

Cheng's recent patent, titled "Method of manufacturing a color filter for a reflective liquid crystal display," introduces a novel approach to fabricating color filters for LCDs. This method involves several critical steps. Firstly, a positive photoresist layer is coated onto a reflective substrate and exposed to light through a finely patterned mask. This creates multiple exposed regions within the photoresist layer. Secondly, one of the exposed regions with the highest energy dose is removed using an alkaline developer, exposing the conductive surface beneath. Consequently, color paint is electrodeposited onto the exposed areas to create the desired color filter layers, which continue to be added until all colors are achieved. The method ensures uniform thickness, better flatness, and high precision in patterns.

Additionally, Cheng's patent for a "liquid crystal panel and method for producing the same" characterizes an innovative design wherein each color filter is compartmentalized by a black matrix. This design allows for effective positioning of spacers that connect to the first conductive film. The production process involves the use of a four-level photoresist system, enabling the creation of the red, green, and blue regions, while spacers are formed through meticulous development and electrodeposition techniques. This ingenuity ensures high-quality display performances with easily determined spacer positions.
