Display device
A display device includes a screen, first and second projectors, a detector, and a controller. The screen has first and second surfaces. The first projector projects a first horizontally non-inverted image as viewed from the first surface. The second projector projects a second horizontally non-inverted image as viewed from the second surface. The detector detects a person viewing the first surface and a person viewing the second surface. The controller controls switching of an operation between the first and second projectors and also performs control, when the detector has detected a person viewing the first surface and a person viewing the second surface, so that the person viewing the first surface and the person viewing the second surface are able to see each other through the screen.
1. A display device comprising:
a display configured to control switching between transparent or translucent and opaque;
a detector; and
a controller configured to, if the detector detects a first person on a side of a first surface of the display and a second person on a side of a second surface of the display, then control the display so that the first person and the second person can see each other through the display,
wherein the display is switchable between a see-through enable state in which the display is see-through and a see-through disable state in which the display is not see-through, and
wherein the controller is configured to, if the detector has detected a person viewing the first surface and a person viewing the second surface, change the display from the see-through disable state to the see-through enable state.
2. The display device according to claim 1 , wherein the controller is configured to progressively change the display from the see-through disable state to the see-through enable state in accordance with at least one of a position of each of the detected persons, a face direction of each of the detected persons, an eye direction of each of the detected persons, and whether each of the detected persons has shown a reaction to the display.
3. A display device comprising:
a display configured to control switching between transparent or translucent and opaque;
a detector; and
a controller configured to, if the detector detects a first person on a side of a first surface of the display and a second person on a side of a second surface of the display, then control the display so that the first person and the second person can see each other through the display,
wherein the detector is configured to detect that a face of the first person is directed at the first surface,
wherein the detector is configured to detect that a face of the second person is directed at the second surface, and
wherein the controller is configured to, if the detector detects that the face of the first person is directed at the first surface and the face of the second person is directed at the second surface, then control the display so that the first person and the second person can see each other through the display.
4. A display device comprising:
a display configured to control switching between transparent or translucent and opaque;
a detector; and
a controller configured to, if the detector detects a first person on a side of a first surface of the display and a second person on a side of a second surface of the display, then control the display so that the first person and the second person can see each other through the display,
wherein the detector is configured to detect that an eye of the first person is directed at the first surface,
wherein the detector is configured to detect that an eye of the second person is directed at the second surface, and
wherein the controller is configured to, if the detector detects that the eye of the first person is directed at the first surface and the eye of the second person is directed at the second surface, then control the display so that the first person and the second person can see each other through the display.
