Latest Patents
Katsube's latest patents include a "Supertwisted nematic liquid crystal device having two phase difference" and a "Liquid crystal display assembly." The first invention relates to a liquid crystal display device that utilizes phase difference plates composed of uniaxial polymer film. These plates are symmetrically placed at both the front and back sides of an STN liquid crystal panel. This configuration allows for nearly ideal wavelength dispersion, compensating for phase difference across the entire wavelength region. As a result, it achieves a colorless display with high contrast. The second patent describes a liquid crystal display unit that integrates both the liquid crystal elements and the drive circuit boards. This unit features a flexible printed circuit board that connects the liquid crystal cell to the drive circuit board, allowing for a compact and efficient assembly.
