Title: Norimasa Sekine: Innovator in Liquid Crystal Display Technology
Introduction
Norimasa Sekine is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of liquid crystal display technology, holding a total of 5 patents. His innovative work focuses on improving manufacturing processes and enhancing the performance of display technologies.
Latest Patents
Sekine's latest patents include a light-condensing film, a liquid-crystal panel, and a backlight, as well as a manufacturing process for the light-condensing film. A conventional liquid crystal display comprises numerous components, which can lead to high manufacturing costs. Sekine's invention addresses this issue by preparing a liquid-crystal panel through the formation of individual optically functional films, a TFT device, and a light-emitting device on a long thin film, which is then laminated by a transfer process. The base film used as a substrate in the liquid-crystal panel is designed to have a thickness of 10 µm to 200 µm, a curvature radius of 40 mm or less, and a coefficient of thermal expansion of 50 ppm/°C or less. This innovation ensures that the mechanical and optical properties remain stable, even under thermal stress.
Another notable patent is for a color EL display and the method for producing it. This invention features a color EL display where color filters, a thin film transistor circuit, an organic EL layer, and a common electrode are laminated in a specific order on a transparent substrate. The production method involves forming color filters, a thin film transistor circuit, an organic EL layer, and a common electrode, with process temperatures kept at 200°C or less.
