Title: **Atsushi Kumano: Pioneering Innovations in Liquid-Crystal Technology**
Introduction
Atsushi Kumano, a distinguished inventor based in Tokyo, Japan, has made significant contributions to the field of liquid-crystal technology. With a remarkable portfolio of 18 patents, his innovative work has the potential to revolutionize display technologies and reduce manufacturing costs.
Latest Patents
Kumano's latest inventions include a light-condensing film, liquid-crystal panel, and backlight, as well as a manufacturing process for the light-condensing film. A key challenge addressed by these innovations is the complexity and high costs associated with conventional liquid crystal displays, which comprise numerous components. Kumano's groundbreaking method involves preparing a liquid-crystal panel by forming individual optically functional films, a TFT device, and a light-emitting device on a long thin film before laminating the film through a transfer process. This results in a more streamlined manufacturing approach. The ideal base film for the substrate in a liquid-crystal panel, according to his design, should have a thickness ranging from 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. Additionally, it should exhibit a variation of ±5% or less in mechanical and optical properties when subjected to a thermal history at 200°C.
