Abstract

An electro-optical display device with a transparent cover and a display, a transparent bonding material being present between the electro-optical display and the transparent cover, the transparent cover being part of a tray, the sides of the tray being designed as a frame, the lateral surfaces of the electro-optical display being surrounded by the frame in a form-fitting manner and the electro-optical display being connected to the frame.

First claim

The invention claimed is:

1. An electro-optical display assembly comprising:
an electro-optical display having:
a display surface,
a rear surface opposite the display surface; and
at least two opposing lateral sides substantially perpendicular to the display surface;

a frame configured to substantially contact the at least two opposing lateral sides of the electro-optical display;
a transparent cover configured as at least part of a trough and configured to connect to an outer perimeter of a first end of the frame, wherein sides of the at least part of the trough are configured as a part of the frame; and
a transparent bonding material arranged between the display surface of the electro-optical display and the transparent cover and configured to adhesively bond the transparent cover to the electro-optical display;
wherein the electro-optical display is enclosed with a form fit by the frame on its side surfaces provided by the frame substantially contacting the lateral sides of the electro-optical display, and
wherein a portion of the lateral side of the electro-optical display at the rear surface is physically connected to a second end of the frame that is opposite the first end of the frame.

2. The electro-optical display as claimed in claim 1 , wherein the at least part of the trough is produced in one piece.

3. The electro-optical display as claimed in claim 1 , wherein the frame is connected by a material fit to the transparent cover.

4. The electro-optical display as claimed in claim 1 , wherein a refractive index of the transparent bonding material is substantially the same as a refractive index of the transparent cover.

5. The electro-optical display as claimed in claim 1 , wherein a surface of the transparent cover is planar.

6. The electro-optical display as claimed in claim 1 , wherein a surface of the transparent cover is curved.

7. The electro-optical display as claimed in claim 1 , further comprising a touch-screen film applied on the transparent cover.

8. The electro-optical display as claimed in claim 7 , wherein the touch-screen film is laminated onto the transparent cover.

9. The electro-optical display as claimed in claim 7 , wherein the touch-screen film is applied on a side of the transparent cover facing toward the electro-optical display.

10. The electro-optical display as claimed in claim 1 , wherein the transparent cover is printed on a side facing away from the electro-optical display in its edge region.

11. The electro-optical display as claimed in claim 1 , wherein the transparent cover is colored.

12. The electro-optical display as claimed in claim 7 , wherein the touch-screen film is applied on a side of the transparent cover facing toward the electro-optical display.

13. The electro-optical display as claimed in claim 7 , wherein the electro-optical display is configured as one of an LCD and an OLED.

14. The electro-optical display assembly as claimed in claim 1 ,
wherein the at least two opposing lateral sides of the electro-optical display are substantially planar and
respective surfaces of the frame configured to substantially contact the at least two opposing lateral sides of the electro-optical display are substantially planar.
