Title: Masahiro Usui: Innovator in Color Projection Technology
Introduction
Masahiro Usui, an accomplished inventor based in Nagaokakyo, Japan, has made significant contributions to the field of display technology. With a total of 7 patents to his name, Usui's innovative work focuses primarily on enhancing color projection systems through the utilization of liquid crystal display elements.
Latest Patents
Among Usui's most notable inventions is a color projection type display apparatus that incorporates three liquid crystal displays. The invention utilizes natural light, which is separated into red, green, and blue illuminating rays through a dichroic mirror. Each ray illuminates a respective liquid crystal display element, carefully controlled by an image signal for optimal transmittance at each pixel. After passing through the displays, the three colored rays are re-synthesized by a second dichroic mirror, forming a coherent light beam. This beam is then enlarged and projected onto a screen using a projecting lens. A key feature of Usui's design is the incorporation of a light source that converts natural light into a linearly polarized beam, allowing for the synchronization of polarizing angles across the illuminating rays, thereby minimizing any loss of light.
