Title: The Innovative Contributions of Yozo Kosaka
Introduction
Yozo Kosaka is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of display technologies, holding a total of 14 patents. His work has been instrumental in advancing the capabilities of various display systems.
Latest Patents
Among his latest patents is the invention of a transfer sheet. This transfer sheet is designed for the formation of electrode patterns, dielectric layers, barrier layers, and more in plasma display panels (PDPs), field emission displays (FEDs), liquid crystal displays (LCDs), fluorescent displays, and hybrid integrated circuits. The transfer sheet consists of a base film and a transfer layer that is releasably provided on the base film, optionally with a protective film. The transfer layer includes an inorganic component, such as glass frit, and an organic component that can be removed by firing, potentially including an electrically conductive powder. By optimizing the surface roughness and gloss of the transfer layer, as well as controlling the residual solvent content, high-accuracy primer layers and dielectric layers can be formed, enabling the creation of high-definition electrode patterns.
Another notable patent is related to the process for producing an electrode for plasma display panels. This process involves coating a photosensitive conductive paste on a film to create a pattern-forming layer. The film is then laminated onto a substrate, exposed through a mask, and developed to remove unexposed areas. Finally, the substrate is fired to adhere the exposed areas of the pattern-forming layer, resulting in a well-defined electrode pattern.
