Latest Patents

Yosuke Sakai holds a patent for an observation optical system and display apparatus. This invention is designed to guide light from a display device to the observation side. The system includes a lens with a first half-transmissive reflective surface and a second half-transmissive reflective surface, which is positioned closer to the display device. The light from the display device transmits through the second half-transmissive reflective surface, reflects on the first half-transmissive reflective surface, and is then guided to the observation side. Notably, the first half-transmissive reflective surface features a metal wire microstructure with a polarization dependency, and the pitch of this microstructure varies according to the height from the optical axis of the lens. This innovative design enhances the overall performance of display systems.
