Title: Naritoshi Kitamura: Innovator in Optical Filter Technology
Introduction
Naritoshi Kitamura is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of optical filter technology, holding two patents that enhance the display quality of electronic devices. His innovative work focuses on the development of optical filters made from inorganic materials, specifically designed to improve the transmission of blue and green light.
Latest Patents
Kitamura's latest patents include an optical filter made of inorganic material for blue light and another for green light. The blue light optical filter is designed to transfer blue light while absorbing all other colored lights. This is achieved by applying an inorganic mixture powder, which is a blend of transparent glass material powder and oxides of cobalt and aluminum, onto a glass substrate and firing it. This invention significantly enhances the contrast of images displayed on devices by reducing ambient light reflection without compromising brightness. Similarly, the green light optical filter operates on the same principle, using a mixture of transparent glass powder and oxides of cobalt, chrome, and aluminum. This filter also improves image contrast by minimizing ambient light reflection.
