Yoshikazu Hazama is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of projection and image display technology. With a total of 6 patents to his name, Hazama continues to push the boundaries of innovation in his industry.
Latest Patents
One of Hazama's latest patents is a projection apparatus and image display apparatus that features individual color light diffusion and a microlens array. This apparatus includes a three-color light source that emits multiple color lights with different wavelengths. A diffraction type optical element performs diffusion forming of these individual color lights. The field lens converts the diffusion-formed individual color lights into parallel lights, while a liquid crystal panel incorporates a microlens array with multiple microlenses arranged in a matrix at the incident regions of the individual parallel color lights. Additionally, the pixel section has three pixel openings aligned with the individual microlenses.
Another notable patent is for a projection liquid crystal display apparatus, which includes a light source that emits white light and a liquid crystal display unit. A holographic optical element is positioned between these two components, serving as the color separating and focusing means. This element separates the white light into its primary color components—red, green, and blue—directing them to the corresponding pixels on the liquid crystal display unit. The holographic optical element is produced using the liquid crystal display unit as an exposure mask, allowing for precise color separation and image reproduction.
