Title: The Innovations of Tadashi Nakagawa

Introduction

Tadashi Nakagawa is a prominent inventor based in Takatsuki, Japan. He has made significant contributions to the field of display technology, particularly in the development of electrode layers for plasma display devices. With a total of 6 patents to his name, Nakagawa's work has had a lasting impact on the industry.

Latest Patents

One of Nakagawa's latest patents is a method of forming electrode layers. This innovative approach involves manufacturing at least two-layer electrodes that can be utilized as bus and data electrodes in plasma display devices. The process includes depositing each layer in a coating step and subsequently exposing the layers simultaneously for development. After this, the layers are baked together, allowing for one layer to be thinner than the other during the time period between the developing step and the baking step.

Another notable patent is for a multi-layered shaped electrode. This manufacturing method is designed for a metal electrode used in bus and data electrodes that make up a display panel, including a Plasma Display Panel (PDP). The method effectively controls the edge curl phenomenon during the photolithographic patterning of the electrodes, making it negligible. This is achieved through a dry step that facilitates solvent flow from regions of high absorbency to those of lower absorbency.
