Title: Akiyoshi Yamada: Innovator in Display Technology
Introduction
Akiyoshi Yamada is a prominent inventor based in Fukaya, Japan. He has made significant contributions to the field of display technology, holding a total of 5 patents. His innovative work focuses on methods that enhance the manufacturing and functionality of image display apparatuses.
Latest Patents
Yamada's latest patents include a method of bonding display substrates by applying an electric current to heat and melt a bonding material. This method involves forming sealing layers on the peripheral edge parts of a front substrate and a rear substrate, which are then disposed to be opposed to each other. Current paths are created in the sealing layers, and a power supply is initiated. An electric current, reaching a maximum value after a current-increasing period of 10% or more of the entire power-supply time, is supplied for a predetermined duration. This process effectively heats and melts the sealing layers, allowing the peripheral parts of the front and rear substrates to be joined.
Another notable patent is related to an image display apparatus, which includes a rear substrate, a front substrate opposing the rear substrate, and a sidewall interposed between them. A phosphor screen is formed on the inner surface of the front substrate, while electron-emitting elements are provided on the rear substrate. An indium layer is formed on a sealing surface between the front substrate and the sidewall. When this indium layer is heated and melted in a vacuum atmosphere, the front and rear substrates are sealed together, with the sidewall interposed.
