Abstract

Claims (57)

1 . A screen unit comprising:

a frame;

a plurality of panels configured to display an image projected by a projector and configured to be detachably attachable to the frame; and

an intermediate member configured to display the image projected by the projector and being provided across the plurality of panels in a state where the plurality of panels are detachably attached to the frame,

wherein each of the plurality of panels comprises a first screen sheet on which a video is projected, a first blocking film configured to block light, and a base material,

wherein the intermediate member comprises a second screen sheet and a second blocking film, and

wherein the first screen sheet on which the video is projected and the second screen sheet have the same optical characteristics as each other, and the first blocking film configured to block light and the second blocking film have the same optical characteristics as each other.

2 . The screen unit according to claim 1 ,

wherein a front side of the first blocking film has specular reflection characteristics, and a front side of the second blocking film has specular reflection characteristics.

3 . The screen unit according to claim 1 ,

wherein the intermediate member further comprises a magnetic sheet on a back surface of the second blocking film.

4 . The screen unit according to claim 3 ,

wherein each of the plurality of panels further comprises a magnet embedded in the base material.

5 . The screen unit according to claim 1 ,

wherein the base material comprises a foamed member.

6 . The screen unit according to claim 1 ,

wherein each of the plurality of panels includes a plurality of holes extending through an entire thickness of each of the plurality of panels.

7 . The screen unit according to claim 6 ,

wherein each of the plurality of holes is filled with a porous material.

8 . The screen unit according to claim 1 , further comprising:

an actuator attached to a back surface of each of the plurality of panels.

9 . The screen unit according to claim 1 ,

wherein the first blocking film comprises an aluminum vapor deposition layer.

10 . The screen unit according to claim 1 ,

wherein the second blocking film comprises an aluminum vapor deposition layer.

11 . The screen unit according to claim 1 ,

wherein the video is projected on a front side of the screen unit, and each of the plurality of panels comprises, in order from the front side of the screen unit to a rear side of the screen unit, the first screen sheet, the first blocking film, and the base material.

12 . The screen unit according to claim 11 ,

wherein the intermediate member comprises, in order from the front side of the screen unit to the rear side of the screen unit, the second screen sheet and the second blocking film.

13 . The screen unit according to claim 1 ,

wherein each of the plurality of panels further comprises a magnet disposed in a peripheral portion of the base material.

14 . The screen unit according to claim 1 ,

wherein each of the plurality of panels is configured to function as a flat screen.

15 . The screen unit according to claim 1 ,

wherein the frame is foldable.

16 . The screen unit according to claim 1 ,

wherein each panel of the plurality of panels includes four corners, and in a state where each panel of the plurality of panels is attached to the frame, the four corners of each panel of the plurality of panels are attached to the frame.

17 . A method for assembling a screen unit, the method comprising:

placing a frame on a placement surface;

attaching a plurality of panels to the frame placed on the placement surface, the plurality of panels being configured to display an image projected by a projector; and

providing an intermediate member across the plurality of panels attached to the frame, the intermediate member being configured to display the image projected by the projector,

wherein each of the plurality of panels comprises a first screen sheet on which a video is projected, a first blocking film configured to block light, and a base material,

wherein the intermediate member comprises a second screen sheet and a second blocking film, and

wherein the first screen sheet on which the video is projected and the second screen sheet have the same optical characteristics as each other, and the first blocking film configured to block light and the second blocking film have the same optical characteristics as each other.

18 . The method according to claim 17 ,

wherein the frame is foldable,

wherein the method further comprises expanding the frame that is in a folded state before attaching the plurality of panels to the frame, and

wherein the plurality of panels are attached to the frame in a state in which the frame is expanded.

19 . A method for disassembling a screen unit, the method comprising:

detaching an intermediate member from a screen unit, the screen unit comprising a frame and a plurality of panels configured to display an image projected by a projector and to be detachably attachable to the frame, the intermediate member being configured to display the image projected by the projector and being provided across the plurality of panels detachably attached to the frame; and

detaching the plurality of panels from the frame,

wherein each of the plurality of panels comprises a first screen sheet on which a video is projected, a first blocking film configured to block light, and a base material,

wherein the intermediate member comprises a second screen sheet and a second blocking film, and

wherein the first screen sheet on which the video is projected and the second screen sheet have the same optical characteristics as each other, and the first blocking film configured to block light and the second blocking film have the same optical characteristics as each other.

20 . The method according to claim 19 ,

wherein the frame is foldable,

wherein the method further comprises folding the frame after detaching the plurality of panels.
