    Abstract: A screen in which observation distance may be adjusted while maintaining image brightness and a projection system using the screen. In a light control layer of a screen, a first angle region that determines a diffusion distribution of a reflected light is different according to the screen position in a control direction in which light diffusion control is performed. Accordingly, a diffusion distribution of image light emitted from a screen surface is adjusted to be tilted downward by an upper end and upward by a lower end according to the screen position. Thus, for example, a size of a diffused angle range is maintained to be 30°, and a direction in which the image light is diffusion-emitted corresponds to an assumed position of an observer. The projection image can be observed while maintaining brightness of an image and the observation distance can be adjusted to be short.

  • Patent number: 8177368
    Abstract: An image projection apparatus includes a projector, a frame, and a partially transparent screen. The frame retains the screen under tension, such that the screen is inclined at an angle with respect to a plane of emission of light from the projector. The screen has a front surface arranged such that light emitted from the projector is reflected therefrom. The projector projects an image such that light forming the image impinges upon the screen such that a virtual image is created from light reflected from the screen, the virtual image appearing to be located behind the screen.

  • Patent number: 8167436
    Abstract: A display shelf system includes a display shelf, which includes a plurality of placing tables which are adapted to have an article placed thereon. A plurality of transmission-type screens are arranged with the placing tables, respectively. A projector projects a projector image, and a light guide of the display shelf leads the projector image onto the rear sides of the transmission-type screens. The transmission-type screens have curved surfaces which are inclined to face toward a lateral direction with respect to a front of the display shelf, so that the transmission-type screens are easily viewable by viewers who are in the lateral directions of the display shelf.

  • Patent number: 8149509
    Abstract: A projection screen apparatus having a retention member configured, in use, to be in contact with at least one surface of a screen along at least a portion of at least one edge of the screen. The projection screen may include polymeric material and the retention member may be bonded to the screen. The retention member may comprise a plurality of apertures and tensioning members extending through the apertures to apply tension to the screen. A portion of each tensioning member extending through the apertures to contact the retention member may be flexible and non-resilient. The retention member may be configured to allow slidable engagement with the plurality of tensioning members. Each retention member may comprise biasing means configured to bias each retention member away from a neighboring retention member, the biasing means adjustable to vary the bias applied when the screen is in situ.
