Latest Patents

Oikawa's latest patents include a method for master pattern production and a method for forming flat display panel phosphor dots. The method for master pattern production involves creating a master pattern used for manufacturing a color picture tube phosphor screen. This innovative approach allows for high accuracy in producing the master pattern by forming an image of an interchangeable shadow mask on the internal surface of the face glass and transferring it onto a photosensitive plate. This method is more cost-effective and simplifies the manufacturing process compared to conventional methods.

The second patent, a method for forming flat display panel phosphor dots, combines a conventional printing method with an optical method. In this process, a paste film containing phosphor, photoresist, and powdered glass is coated on the surface of a dielectric layer. The paste layer is then irradiated with ultraviolet light through a mask, and after development, the hardened portions undergo heat treatment. This technique allows for the precise formation of phosphor dots at predetermined locations on the dielectric layer.
