Title: Innovations by Shuji Aruga
Introduction
Shuji Aruga is a prominent inventor based in Suwa, Japan. He has made significant contributions to the field of projection display technology, holding a total of seven patents. His work focuses on enhancing image quality and reducing reflection errors in projection systems.
Latest Patents
One of his latest patents is a projection display employing circular polarized light for reflection. This innovative display prevents reflected light beams produced during optical modulation or light compositing from reinjecting into the modulating liquid crystal panel. It also converts projected light or light impinged into a light compositing system into a linearly polarized light beam. This technology allows for the projection of high-contrast, high-intensity images with minimal reflection errors. The display includes a light source, an optical modulation system, and a projector system designed to enhance the viewing experience.
Another notable patent is a projection-type display device that utilizes a single light source to produce light. This device features a first dichroic mirror group that separates the light into colored components. A transmissive light valve system modulates the colored light, while a second dichroic mirror group synthesizes the modulated light for projection onto a screen.
