Title: Innovator Kazuyuki Hasegawa: Pioneering Advances in Plasma Display Technology

Introduction

Kazuyuki Hasegawa is a distinguished inventor based in Settsu, Japan, known for his significant contributions to the field of display technology. With a total of five patents to his name, Hasegawa has played a crucial role in advancing plasma display panel (PDP) innovations, ensuring both improved performance and efficiency in the technology.

Latest Patents

Hasegawa's recent innovation focuses on a plasma display panel and a method for producing the same, along with a material for the protective layer of such a panel. His patent describes a PDP that incorporates a front plate along with scan and sustain electrodes that are formed on that front plate. The dielectric layer covering these electrodes is paired with a protective layer composed of silicon (Si) and nitrogen (N), achieved through the use of magnesium oxide (MgO). Notably, the Si atoms’ count is maintained within a range of 5×10^pieces/cm to 8×10^pieces/cm. This construction results in a reduced discharge-delay time, enhancing the response time of the discharge to voltage applications while minimizing variations in discharge-delay times under different temperature conditions.

Furthermore, his invention elaborates on a plasma display panel that features a first and a second substrate designed to face each other, creating a discharge space between them. This panel includes a scan electrode and a sustain electrode situated on the first substrate, along with the dielectric layer and protective layer. The protective layer integrates MgO and at least one element from silicon, germanium, carbon, and tin, alongside elements from the fourth, fifth, sixth, and seventh groups of the periodic table. This configuration enables the panel to exhibit stable discharge characteristics, crucial for consistent image display.
