  • Patent number: 11256089
    Abstract: There is provided a lens array and an lens array capable of suitably preventing irregular brightness without reducing resolution. A micro lens array of a screen includes upper-level microlenses and lower-level microlenses which are formed on the incidence surface of the screen, which have the same effective diameter, and which have a structure that generates an optical path length difference ? in transmission light. By disposing the upper-level microlenses and the lower-level microlenses at an interval based on the effective diameter, the basic periodic structure of a lens period is formed. Further, the upper-level microlenses and the lower-level microlenses form a basic block comprising a combination of the lenses having a structure that generates the optical path length difference. A concave-and-convex period PC based on the basic block is an integer multiple of the lens period.

  • Patent number: 11187910
    Abstract: The purpose of the present invention is to enable information presented by an additionally displayed virtual image to be displayed in an easily recognizable manner. A projection unit projects, towards a projection-receiving part, display light capable of displaying virtual images in positions having different display distances from a viewer. A display distance determination unit is capable of adjusting, in a depth direction, the display distances of the virtual images displayed by the projection unit. If a display addition determination unit determines that a virtual image is to be additionally displayed, the display distance of an existing virtual image already displayed and the display distance of a virtual image to be additionally displayed are made to be different.
