  • Publication number: 20230367536
    Abstract: In a cooperative display system that connects a portable terminal and a head mounted display to display information in cooperation, the portable terminal displays information on a first display, and transmits at least a part of the information that is displayed to the head mounted display, and the head mounted display shares and displays the information transmitted from the portable terminal on a second display. Here, the information displayed on the portable terminal is hierarchical information, and the information displayed on the head mounted display is lower-level information in the hierarchical information. In addition, whether a user is stationary or moving is detected by a sensor of the portable terminal, and in a case where the user is stationary, the display of the information on the portable terminal is stopped, and the information is displayed only on the head mounted display.

  • Patent number: 11817038
    Abstract: To make a display device inconspicuous. A display system includes a base and a display device attached to the base. The display device includes a plurality of inorganic light emitters arrayed in a matrix with a row-column configuration and a surface layer. The surface layer is provided in a traveling direction of light emitted from the inorganic light emitters with respect to the inorganic light emitters and includes a plurality of transmission parts and a blocking part. The transmission parts are provided in a matrix with a row-column configuration so as to overlap the inorganic light emitters when viewed from the traveling direction of the light and allow the light from the inorganic light emitters to pass therethrough. The blocking part blocks the light from the inorganic light emitters. The inorganic light emitters are provided overlapping the transmission parts provided to the surface layer.
