Title: Innovations of Tatsumi Takahashi
Introduction
Tatsumi Takahashi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of liquid crystal displays, holding a total of 5 patents. His work focuses on improving manufacturing processes and reducing costs associated with liquid crystal technology.
Latest Patents
Takahashi's latest patents include innovations such as a light-condensing film, a liquid-crystal panel, and a backlight, along with the manufacturing process for the light-condensing film. A conventional liquid crystal display comprises numerous components, which can lead to high manufacturing costs. Additionally, large-area substrates pose challenges in shipping. His invention addresses these issues 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 for flexibility, and a coefficient of thermal expansion of 50 ppm/°C or less. Furthermore, it is optimized to maintain a variation of ±5% or less in mechanical and optical properties when subjected to thermal history at 200°C.
