Abstract

The disclosure, which relates to a display device is created so that it can be integrated in a surface, providing in particular a seamless extension and an integrated appearance between the surface surrounding the display device and the display device itself and thus appears to the viewer of the display device as being part of a surface.

Claims

1. A display device, comprising:

a light emitting display;

a light source;

an electrical tint film;

a diffusion disk; and

a cover surface arranged on the light emitting display,

wherein between the light emitting display and the cover surface there is arranged the electrical tint film,

wherein in an area around the light emitting display there is arranged the diffusion disk,

wherein the light source is disposed adjacent the diffusion disk, and

wherein the cover surface is formed with a coloration, wherein an intensity of the coloration increases from a middle, central region of the cover surfaces to border areas of the cover surface.

2. The display device as claimed in claim 1, wherein the coloration of the cover surface has the shape of a rectangle.

3. The display device as claimed in claim 1, wherein the coloration of the cover surface has the shape of an ellipse.

4. The display device as claimed in claim 1, wherein the electrical tint film is arranged over the entire area of the cover surface on the side of the cover surface facing away from a viewer of the display device.

5. The display device as claimed in claim 1, wherein the light emitting display is defined as a TFT.

6. The display device as claimed in claim 1, wherein the light emitting display is defined as a LCD.

7. The display device as claimed in claim 1, wherein the light emitting display is defined as an OLED display.

8. The display device as claimed in claim 1, wherein the light emitting display is defined as a LED display.

9. The display device as claimed in claim 1, wherein the light sources is arranged behind the diffusion disk in the form of a matrix with several rows and columns.

10. The display device as claimed in claim 1, wherein the light emitting display, the cover surface, the light source, and the diffusion disk are optically bonded with each other.

11. A display device, comprising:

a light emitting display;

a cover surface arranged on the light emitting display,

an electrical tint film having at least one layer arranged between the light emitting display and the cover surface;

a diffusion disk arranged around the light emitting display; and

at least one light source disposed adjacent the diffusion disk,

wherein the cover surface is formed with a coloration, wherein an intensity of the coloration increases from a middle, central region of the cover surfaces to border areas of the cover surface.

12. The display device as claimed in claim 11, wherein an appearance of the at least one layer of the electrical tint film is changed in response to the application of an electrical field.

13. The display device as claimed in claim 12, wherein the appearance of the at least one layer of the electrical tint film is changed from a nontransparent state to a transparent state in response to the application of the electrical field.

14. The display device as claimed in claim 11, wherein the electrical tint film is arranged over the entire area of the cover surface on the side of the cover surface facing away from a viewer of the display device.

15. The display device as claimed in claim 11, wherein the coloration of the cover surface is formed in a shape, wherein the shape is selected from the group consisting of a rectangle and an ellipse.

16. The display device as claimed in claim 11, wherein the light emitting display is selected from the group consisting of a TFT, a LCD, an OLED display and a LED display.

17. A display device, comprising:

a light emitting display;

a cover surface arranged on the light emitting display,

an electrical tint film having at least one layer arranged between the light emitting display and the cover surface, wherein an appearance of the at least one layer of the electrical tint film is changed in response to the application of an electrical field;

one or more diffusion disks arranged around the light emitting display, wherein the one or more diffusion disks cooperate to form a frame arranged around the light emitting display; and

at least one light source disposed adjacent each of the one or more diffusion disks, wherein the at least one light source is arranged in a matrix with several rows and columns behind each of the one or more diffusion disks,

wherein the cover surface is formed with a coloration, wherein an intensity of the coloration increases from a middle, central region of the cover surfaces to border areas of the cover surface.

18. The display device as claimed in claim 17, wherein the appearance of the at least one layer of the electrical tint film is changed from a nontransparent state to a transparent state in response to the application of the electrical field.

19. The display device as claimed in claim 17, wherein the coloration of the cover surface is formed in a shape, wherein the shape is selected from the group consisting of a rectangle and an ellipse.
