Title: Kazuhiro Kuwabara: Innovator in Display Technology
Introduction
Kazuhiro Kuwabara is a prominent inventor based in Hitachi, Japan. He has made significant contributions to the field of display technology, holding a total of 8 patents. His work focuses on enhancing the performance and capabilities of display apparatuses.
Latest Patents
One of Kuwabara's latest patents is for a display apparatus that includes an optical modulation element. This innovative display apparatus is capable of adapting to an increase in display frequency, even when using an optical modulation element with a relatively low response speed. It can rewrite images at high speeds by separately mapping display data for each pixel and applying gradation information. The apparatus divides the display period of one frame into multiple sub-frames, allowing for independent control of the input value for the optical modulation element in each sub-frame, resulting in a high-quality gradation display.
Another notable patent is for a reflective color liquid crystal display apparatus. This apparatus consists of pixels and includes a first electrode substrate, a second electrode substrate, and a liquid crystal layer. The first electrode substrate features a polymer layer with randomly arranged protrusions or depressions on a glass substrate, along with a reflective layer, color filters, transparent electrodes, and an alignment layer. The second electrode substrate is designed to face the alignment layer of the first substrate, creating an interval filled with liquid crystal composition. The reflective layer is uniquely designed, with portions corresponding to each pixel colored black, enhancing the display's visual quality.
