Abstract

A display device and a temperature control unit having the same are disclosed. The display device includes a substrate with a display element, and a transparent plate which is in contact with the substrate and has a larger area than that of the substrate.

Claims

1. A display device comprising:

a substrate with a display element; and

a transparent plate which is in contact with the substrate and has a larger area than that of the substrate.

2. The display device according to claim 1, wherein the transparent plate seals the display element.

3. The display device according to claim 1, wherein the display element is an OLED (Organic Light Emitting Diode).

4. The display device according to claim 3, wherein the OLED is formed to include an anode, a light emitting layer and a cathode, and conductive lines are formed on the transparent plate to be independently connected to the anode and the cathode of the OLED.

5. The display device according to claim 4, wherein the conductive lines are formed of a transparent conductive material.

6. The display device according to claim 5, wherein the transparent conductive material is selected from a group consisting of ITO, IZO, SiO₂ and ZnO.

7. The display device according to claim 4, wherein the conductive lines are formed of metal.

8. The display device according to claim 1, wherein the transparent plate is formed as a chromatic plate to change a color of light emitted from the display element.

9. The display device according to claim 1, wherein the display element is formed of pixels to display text or image information.

17. A terminal having a body in contact with the display device described in claim 1.

18. The terminal according to claim 17, wherein the transparent plate has the same shape as one surface of the body of the terminal.

19. A temperature control unit having a body in contact with the display device described in claim 1.

20. A power unit having a body in contact with the display device described in claim 1.

10. A display device comprising:

a substrate with a display element;

an encapsulating plate formed on the substrate; and

a transparent plate with the encapsulating plate inserted therein.

11. The display device according to claim 10, wherein the encapsulating plate has a smaller area than that of the substrate.

12. The display device according to claim 10, wherein the display element is an OLED.

13. The display device according to claim 12, wherein the OLED is formed to include an anode, a light emitting layer and a cathode, and conductive lines are formed on the transparent plate to be independently connected to the anode and the cathode of the OLED.

14. The display device according to claim 13, wherein the conductive lines are formed of a transparent conductive material.

15. The display device according to claim 14, wherein the transparent conductive material is selected from a group consisting of ITO, IZO, SiO₂ and ZnO.

16. The display device according to claim 10, wherein the encapsulating plate is formed as a chromatic plate to change a color of light emitted from the display element.
