  • Publication number: 20220252898
    Abstract: The display device includes a mirror display element, a display, an optical element array, an external light reflection suppression layer, and a driving unit. The mirror display element reflects a part of external light and transmits a part of the external light. A display is disposed on an opposite side of an outer surface of the mirror display element, in which a plurality of pixels are two-dimensionally arranged. An optical element array is disposed between the mirror display element and the display in parallel with a light emission surface of the display, in which a plurality of optical elements corresponding to a predetermined unit of pixels among the plurality of pixels are arranged. An external light reflection suppression layer is disposed between the mirror display element and the display to suppress reflection of the external light. The driving unit drives the display to turn on a predetermined pixel among the plurality of pixels.

  • Publication number: 20220013046
    Abstract: A virtual image display system includes an image data producing unit, an image display, and an optical system. The image data producing unit produces, based on image data of a rendering target and position information about a display position of the target, image data to display a virtual image of the target. The image display displays, on a display screen, an image based on the image data to display the virtual image. The display screen is arranged to be tilted with respect to an optical path leading from the display screen to the optical system. The image data of the rendering target includes first image data of a stereoscopic rendering target. The image data producing unit produces, based on the first image data and position information about a display position of the stereoscopic rendering target, second image data to make the user view the stereoscopic rendering target stereoscopically.
