Title: Kazuhisa Hemmi: Innovator in Flat Display Technology

Introduction

Kazuhisa Hemmi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of display technology, holding a total of 5 patents. His innovative work focuses on enhancing the efficiency and functionality of flat display panels.

Latest Patents

One of Hemmi's latest patents involves a cell drive-type flat display panel. In this design, a metal electrode pad and common signal line are strategically placed outside the effective area facing a recessed portion that forms a cell. The individual cell electrode is connected to the metal electrode pad, while the metal electrode does not extend toward the effective area, ensuring that each cell electrode remains uncovered. This structure allows for a flatter design of the cell electrodes and reduces the drive voltage due to the effects of a suppressed dielectric film. Additionally, the metal electrode pad features a top surface with a pin electrode, and the dielectric layer has an opening that exposes the metal electrode pad, preventing unwanted contact with reactive materials.

Another notable patent by Hemmi is for a panel display with a fluorescent layer. In this design, electric discharge occurs in a concave portion to generate ultraviolet light, which then interacts with a fluorescent layer to emit visible light. The arrangement of spherical materials on the inner surface of the concave portion enlarges the surface area of the fluorescent layer, enhancing the conversion efficiency from ultraviolet to visible light.
