Title: Shigeo Haruki: Innovator in Plasma Display Technology

Introduction

Shigeo Haruki, an eminent inventor based in Nagaokakyo, Japan, has made significant contributions to the field of display technology. With a total of two patents to his name, Haruki has focused on improving the efficiency and quality of plasma display panels through innovative manufacturing methods.

Latest Patents

One of Haruki's latest patents outlines a manufacturing method for a plasma display panel with superior luminescence. This innovative method ensures that the plasma display panel (PDP) operates with high luminous efficiency, reproducing colors with greater fidelity. The design includes a sealant layer formed around the main surfaces of the front and back panels of the PDP. Notably, protrusions and depressions are integrated into the sealant layer, creating gaps around the panel's periphery. During the sealing process, heating is conducted in a dry gas atmosphere, allowing moisture to exit the inner space of the PDP through these gaps. This process significantly reduces heat deterioration, particularly in the blue phosphor layer.

Additionally, Haruki's patent on the plasma display panel itself reveals a design featuring multiple phosphor layers that emit different colors of fluorescent light. At least one phosphor layer is formed from a mixed phosphor that combines phosphors with both negative and positive surface potentials. This innovative approach alters the surface potential from negative to positive, thus minimizing discharge errors and variations, which ultimately enhances the overall display quality.
