Abstract

Disclosed in the present invention is a transparent display device. The transparent display device according to the present invention comprises: a frame having first and second apertures; a transparent display panel disposed on the first aperture of the frame; and a control module, disposed on the second aperture of the frame, for controlling the transparent display panel, wherein the frame is installed to cover the front surface of the door unit of a certain product or is separated from the front surface of the door unit of the certain product, and wherein an extension frame extended from an edge of the frame toward the door unit of the certain product can engage with the side of the edge of the door unit of the certain product.

Claims

1. A transparent display device, comprising:

a frame including a first opening and a second opening;

a transparent display panel disposed on the first opening of the frame; and

a control module controlling the transparent display panel by being disposed on the second opening of the frame,

wherein the frame is installed to cover a front surface of a door unit of a prescribed product or separated from the front surface of the door unit of the prescribed product and

wherein an extending frame extending from a rim of the frame in a direction of the door unit of the prescribed product and a lateral surface of a rim of the door unit of the prescribed product are jointed together.

2. The transparent display device of claim 1, wherein a size of the first opening of the frame is different from that of the second opening.

3. The transparent display device of claim 1, wherein a transparent cover is disposed in front of the first opening of the frame and wherein a non-transparent cover is disposed in front of the second opening of the frame.

4. The transparent display device of claim 3, wherein a rear surface of the transparent cover comes into contact with a front surface of the transparent display panel.

5. The transparent display device of claim 3, wherein a rear surface of the transparent cover is disposed in a manner of being spaced apart from a front surface of the transparent display panel.

6. The transparent display device of claim 5, wherein a transparent adhesive is disposed between the rear surface of the transparent cover and the transparent display panel.

7. The transparent display device of claim 6, wherein the transparent adhesive is disposed on an edge of the front surface of the transparent display panel.

8. The transparent display device of claim 3, wherein an anti-reflective (AR) coating layer is formed on a front surface of the transparent cover.

9. The transparent display device of claim 1, wherein an airgap is formed between a rear surface of the transparent display panel and the front surface of the door unit of the prescribed product.

10. The transparent display device of claim 1, wherein a gap adjusting unit configured to adjust a gap between a rear surface of the transparent display panel and the front surface of the door unit of the prescribed product is disposed in the frame.

11. The transparent display device of claim 1, the gap adjusting unit, comprising:

an adjusting plate extending from the rim of the frame in a direction of the first opening; and

a hinge configured to connect a space between the adjusting plate and the frame and rotationally move the adjusting plate in the direction of the door unit of the prescribed product.

12. The transparent display device of claim 1, wherein a ventilating unit configured to discharge heat generated from the control module into a space between a rear surface of the transparent display panel and the front surface of the door unit of the prescribed product is disposed in the second opening of the frame.

13. The transparent display device of claim 1, the frame, comprising:

an inner frame coming into contact with the rim of the door unit of the prescribed product; and

an outer frame disposed in a manner of being spaced apart from the inner frame.

14. The transparent display device of claim 13, wherein the inner frame is attached to a rim of a transparent cover covering the first opening and wherein the outer frame is spaced apart from the transparent cover.

15. The transparent display device of claim 14, wherein an infrared touch sensor is disposed between the outer frame and the transparent cover.

16. The transparent display device of claim 13, wherein a wiring connecting the control module and the transparent display panel electrically is disposed between the inner frame and the outer frame.

17. The transparent display device of claim 1, wherein the control module controls the transparent display panel to display information related to goods stored in the door unit of the prescribed product.

18. The transparent display device of claim 1, wherein the control module controls the transparent display panel to simultaneously display a transmissive region capable of transmitting light and a non-transmissive region incapable of transmitting light.

19. The transparent display device of claim 18, wherein the control module controls the transparent display panel to display information related to goods stored in the door unit of the prescribed product on the non-transmissive region.

20. The transparent display device of claim 18, wherein the control module controls the transparent display panel to display information related to goods viewable through the transmissive region on the non-transmissive region.
