Title: Innovations of Yu-Shin Hu in Cathode Ray Tube Technology

Introduction

Yu-Shin Hu is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of cathode ray tube (CRT) technology. His innovative work has led to advancements that enhance video image quality and color purity.

Latest Patents

Yu-Shin Hu holds a patent for a shadow mask used in color CRTs. This invention focuses on improving the design of the shadow mask, which serves as a color selection electrode in multi-electron beam color CRTs. By increasing the length of the individual elongated beam passing apertures while reducing the width of the bridge portion between adjacent apertures, the surface area of the mask is minimized. This design reduces thermal deformation, or doming, of the shadow mask, which in turn decreases the landing shift of electron beams on phosphor elements. The patent demonstrates that electron beam transmission can be increased by as much as 22%, leading to a 17% increase in video image brightness and improved color purity.
