Abstract

A display device has a projector having a light guide plate that guides light incident from an end portion and deflects the light guided to emit the light from a projection surface facing a viewer in a first direction, the projector being configured to emit light from the projection surface to project an image in a space viewable by the viewer, and a rotator configured to rotate the projector around the first direction. When a first end on the projection surface is located at a first position being an upper side in a second direction orthogonal to the first direction, the image is viewed as a stereoscopic image by the viewer. When the rotator rotates the projector and the first end is located at a second position different from the first position, the image is viewed as a planar image by the viewer.

First claim

The invention claimed is:

1. A display device comprising:
a projector having a light guide plate that guides light incident from an end portion and deflects the light guided to emit the light from a projection surface facing a viewer in a first direction, the projector being configured to emit light from the projection surface to project an image in a space viewable by the viewer;
a rotator configured to rotate the projector around the first direction; and
a plurality of light sources comprising a first light source and a second light source,
wherein, when a first end on the projection surface is located at a first position being an upper side in a second direction orthogonal to the first direction, the image is viewed as a stereoscopic image by the viewer,
wherein, when the rotator rotates the projector and the first end is located at a second position different from the first position, the image is viewed as a planar image by the viewer,
wherein the first light source extinguishes light when the rotator rotates the projector, and the first light source emits light when the first end of the projector is located at the second position based on a rotation instruction of the rotator, and
wherein when the first end is located at the second position, the second light source emits light, the second light source being different from the first light source that emits light when the first end is located at the first position.

2. The display device according to claim 1 , wherein the second position is an upper side in a third direction orthogonal to the first direction and the second direction.

3. The display device according to claim 2 , wherein the rotator is connected to a back surface of the projection surface of the projector to rotate the projector.

4. The display device according to claim 2 , wherein the rotator is connected to a side end portion of the projection surface of the projector to rotate the projector.

5. The display device according to claim 2 , wherein the rotator rotates the projector at a timing not based on viewer's instruction.

6. The display device according to claim 1 , wherein the rotator is connected to a back surface of the projection surface of the projector to rotate the projector.

7. The display device according to claim 6 , wherein the rotator rotates the projector at a timing not based on viewer's instruction.

8. The display device according to claim 1 , wherein the rotator is connected to a side end portion of the projection surface of the projector to rotate the projector.

9. The display device according to claim 8 , wherein the rotator rotates the projector at a timing not based on viewer's instruction.

10. The display device according to claim 1 , wherein the first light source moves with rotation of the projector.

11. The display device according to claim 10 , wherein the rotator rotates the projector at a timing not based on viewer's instruction.

12. The display device according to claim 1 , wherein the rotator rotates the projector at a timing not based on viewer's instruction.

13. A game machine comprising the display device according to claim 1 .

14. A display method in a display device including:
a projector having a light guide plate that guides light incident from an end portion and deflects the light guided to emit the light from a projection surface facing a viewer in a first direction, the projector being configured to emit light from the projection surface to project an image in a space viewable by the viewer;
a rotator configured to rotate the projector around the first direction; and
a plurality of light sources comprising a first light source and a second light source,
wherein the display method comprises:
a stereoscopic image viewing step in which the rotator rotates the projector such that a first end on the projection surface is located at a first position being an upper side in a second direction orthogonal to the first direction, to cause the viewer to view the image as a stereoscopic image; and
a planar image viewing step in which the rotator rotates the projector such that the first end is located at a second position different from the first position, to cause the viewer to view the image as a planar image,
wherein the first light source extinguishes light when the rotator rotates the projector, and the first light source emits light when the first end of the projector is located at the second position based on a rotation instruction of the rotator, and
wherein when the first end is located at the second position, the second light source emits light, the second light source being different from the first light source that emits light when the first end is located at the first position.
