Title: Innovations of Kouji Tashiro
Introduction
Kouji Tashiro is a notable inventor based in Hachioji, Japan. He has made significant contributions to the field of optical materials and displays. With a total of seven patents to his name, Tashiro's work has advanced the technology used in various display applications.
Latest Patents
Tashiro's latest patents include a retardation film, an elongated circularly polarizing plate, and an organic EL display produced using the retardation film. The retardation film features a slow axis with an angle of 10 to 80 degrees relative to its longitudinal direction. It contains cellulose acylate with a degree of acyl substitution ranging from 2.0 to 2.7, along with a regulating agent. The film exhibits an in-plane retardation, measured at a wavelength of 550 nm, ranging from 115 to 260 nm. Additionally, the retardation film has a ΔRo of 3 to 30 nm, where ΔRo is defined as Ro550 - Ro450, with Ro450 being the in-plane retardation measured at a wavelength of 450 nm. Furthermore, the retardation film without the regulating agent has an in-plane retardation, Rc550, and ΔRc (Rc550 - Rc450) that is equal to or greater than 0, where Rc450 is the in-plane retardation measured at a wavelength of 450 nm. Another significant patent involves a circularly polarizing plate and a three-dimensional image display apparatus. This circularly polarizing plate consists of a polarizer and two λ/4 plates bonded to both sides of the polarizer. The in-plane retardation values of the λ/4 plates are designed to meet specific criteria under controlled environmental conditions.
