Latest Patents

Among Kenji Hosaki's notable patents is the design for an "Elliptical Polarizer and Liquid Crystal Display Device." This invention aims to produce an optical element using a liquid crystal film without a supporting substrate film to reduce weight. Often, such films face challenges including wrinkly deformation and cracking due to strain during manufacturing. Hosaki's elliptical polarizer features a thinned optical anisotropic element that is designed to avoid these issues, consisting of a polarizer, an optical anisotropic element with a liquid crystalline substance layer, an adhesive layer, and a stress-blocking layer.

Another significant patent is the "Heads-Up Display System with Optical Rotation Layers." This technology comprises a transparent plate and a liquid crystal display that generates display light at a 45-degree polarization angle. The system includes a first optical rotation layer that rotates the plane of polarization by 90 degrees and a second layer that rotates it by 45 degrees, enhancing the display's effectiveness by allowing S-polarized light to be reflected in a manner that directs it toward the operator's eye.
