Transparent screen, video projection laminated plate, and video display system
There is provided a transparent screen which is capable of separating a direction where a hot spot is observed and a direction where a bright video is allowed to be observed, and establishing a direction where a video is allowed to be wholly brightly observed. A transparent screen includes a first transparent layer, a reflective layer reflecting projected video light, a second transparent layer disposed opposite to the first transparent layer with respect to the reflective layer so as to make a background visible therethrough; wherein the reflective layer has a plurality of slant reflective surfaces, each of the slant reflective surfaces being slant to a reference surface that is a surface of the first transparent layer opposite to the reflective layer; wherein each of the slant reflective surfaces is provided with a concavo-convex and is formed in a stripe shape when seen from a normal direction of the reference surface; and wherein the slant reflective surfaces are disposed so as to have angles to the reference surface, the angle changing with random variations in of range with respect to a certain central angle.

Tiling screen and multi-projection system
The tiling screen (screen) is provided with a plurality of projection areas, and includes an overlapping area where end parts of the projection areas overlap each other, wherein when setting a number of times of overlapping to one in the overlapping area, reflectance in the overlapping area where the number of times is one is configured to be lower than reflectance in an area where the projection areas fail to overlap each other, and when setting the number of times of overlapping to N (N≥2) in the overlapping area, the reflectance in the overlapping area where the number of times is N is configured to be lower than the reflectance in the overlapping area where the number of times of overlapping is a largest number of the numbers of times smaller than N.
PROJECTION SCREEN
The projection screen includes a reflective layer and a light-absorbing layer, where the reflective layer is configured to receive and reflect projection light, and the light-absorbing layer is arranged on the reflective layer; the light-absorbing layer includes a plurality of irregularly arranged light-absorbing members; and the light-absorbing members are configured to absorb at least a part of the projection light, so as to make a brightness of a projected image uniform.

Display systems and methods
Display systems include a display structure having a display surface, and an optical projector that is positioned relative to the display structure and that is configured to project an image onto the display surface. Vehicles include a display system and vehicle structures, in which one vehicle structure includes the display structure of the display system and another vehicle structure includes the optical projector of the display system. Display methods include projecting an image onto a display surface.
Dome screen, dome screen projection apparatus, and method for fabricating the same
A dome screen projection apparatus has screen members made of synthetic resin and detachably joined together to form a dome screen having a curved configuration. Frame members are detachably connected together to form a frame, and suspension members suspend the dome screen in a suspended condition from the frame. The frame members include frame column members disposed on the outside of the dome screen, one at each side of the dome screen and one at the rear of the dome screen, a frame beam member supported at opposite ends at upper portions of the two frame column members at each side of the dome screen and extending above the top front portion of the dome screen, and a frame arc-shaped beam member supported at upper portions of the frame column members. A projector is supported by the frame and projects an image on an inner face of the dome screen while the dome is in the suspended condition. The dome screen may have a generally hemispherical shape with an open front that enables viewers located in front of the dome screen to view an image projected on the inner face of the dome screen. The dome screen projection apparatus can be easily assembled and disassembled on site and moved to another site for assembly and disassembly.
