Display apparatus including a transparent electronic monitor
A display apparatus includes a transparent electronic display such as a non-backlit LCD screen, a display area disposed behind the transparent electronic display, and a light source for illuminating the display area. When the light source is activated, the pixels of the LCD screen, and objects behind the screen, become visible. Various examples of the display apparatus include additional enhancements to the visual image and/or functionality. These enhancements include additional monitors for coordinated displays, user-controlled turntables with coordinated informational displays, parallax compensation, RFID sensors for identifying objects to be displayed, and switchable liquid crystal films and/or polarized mirror coatings to further control revealing and concealing of objects behind the screen. Some examples of the display apparatus may include an animal habitat. The animal habitat may be selectively revealed or concealed. The display apparatus may incorporate screen displays with animal movements for unique visual effects.
1. An animal habitat, comprising:
an enclosure having a floor, a pair of sides, a back, and a substantially transparent front;
a non-backlit video display screen disposed at the front of the display case;
a switchable LCD film disposed on a back surface of the non-backlit video display;
means for selectively supplying power to the switchable LCD film;
a central processing unit operatively connected to the non-backlit video display;
at least one peripheral device that is structured to provide care for animals within the animal habitat, the at least one peripheral device being operatively connected to the central processing unit; and
means for interacting with the non-backlit video display screen or the central processing unit to control the at least one peripheral device.
2. The animal habitat according to claim 1 , further comprising means for displaying status information for the peripheral device on the non-backlit video display.
3. The animal habitat according to claim 1 , wherein the means for interacting with the non-backlit video display screen are selected from the group consisting of the non-backlit video display being a touch screen, a gesture sensor operatively connected to the central processing unit, a keyboard, a mouse, and a touch pad.
4. The animal habitat according to claim 1 , wherein the at least one peripheral device is selected from the group consisting of a heating system, a feeding system, and a filtering system.
5. An animal habitat, comprising:
an enclosure having a floor, a pair of sides, a back, and a substantially transparent front;
a non-backlit video display screen disposed at the front of the display case;
a sensor structured to track movements of aminals within the enclosure;
a central processing unit that is structured to cause the non-backlit video display to display indicia that changes in response to the movements of animals within the enclosure.
6. The animal habitat according to claim 5 , wherein the indicia displayed on the non-backlit video display moves in response to the movements of animals within the enclosure.
7. The animal habitat according to claim 6 , wherein movement of the indicia displayed on the non-backlit video display tracks movement of animals within the animal habitat.
8. The animal habitat according to claim 6 , further comprising:
a camera or sensor structured to detect a position of a viewer; and
a central processing unit structured to move indicia displayed on the non-backlit video display in response to the position of the viewer.
9. The animal habitat according to claim 8 , wherein the central processing unit is structured to respond to a presence of more than one viewer.
10. The animal habitat according to claim 9 , wherein the central processing unit is structured to cease moving the indicia if more than one viewer is present.
11. The animal habitat according to claim 9 , wherein the central processing unit is structured to designate a primary viewer, to move the indicia in response to movements of the primary viewer, and to ignore positions and movements of other viewers.
12. The animal habitat according to claim 9 , wherein the central processing unit is structured to calculate an average viewer position and to move the indicia in response to the average viewer position.
13. A method of displaying an object, comprising:
providing a display case, the display case having:
a non-backlit video display screen forming a front of the display case;
a light source within the display case;
a switchable LCD film disposed on a back surface of the non-backlit video display; and
means for selectively supplying power to the switchable LCD film; and
selectively applying and removing power to the switchable LCD;
whereby viewing of the object through the non-backlit video display, as well as reading indicia displayed on the video display screen, are possible when the light source is lit and the switchable LCD film has power applied, and viewing indicia displayed on the video display screen, but not viewing the object through the display screen, are possible when no power is applied to the switchable LCD film.
