Latest Patents

Kimura’s listed patent work addresses the performance and production of polarizing plates used in display technologies.

One invention describes a polarizing plate designed to improve productivity and reduce unevenness caused by water. It combines a cellulose-resin retardation film and a protective film with a polarizer, using adhesive layers to join the components. The patent specifies a dimensional change rate of no more than 0.1% after the plate is immersed in water and then conditioned under defined temperature and humidity.

Another invention focuses on reducing display unevenness while maintaining a neutral hue and cross property, including when a protective film with low water-vapor permeability is used. The design specifies limits for the polarizing film’s absorbance ratio, the plate’s hue value, and the protective film’s water-vapor permeability.
