Abstract

The present disclosure relates to a display element with disappearance technology and to a method for producing such a display element. The display element has a display assembly with a display panel and a backlight arranged behind the display panel. The display element also has a stabilization assembly with a cutout for accommodating the display assembly, and a decorative film, which is attached at least to a top side of the stabilization assembly and extends over the cutout for the display assembly.

First claim

The invention claimed is:

1 . A display element comprising:
a display assembly with a display panel and a backlight arranged behind the display panel; a stabilization assembly with a cutout for accommodating the display assembly; and a decorative film, which is attached at least to a top side of the stabilization assembly and extends over the cutout for the display assembly, wherein the stabilization assembly mechanically stabilizes the decorative film, wherein a portion of the decorative film in a display region located above the display assembly is thinner than a portion of the decorative film in a peripheral region extending around the display assembly.

2 . The display element as claimed in claim 1 , wherein the decorative film is attached to the top side of the stabilization assembly by adhesive bonding, pressing or hot stamping.

3 . The display element as claimed in claim 1 , wherein a thickness of the decorative film is greater than 200 μm.

4 . A display element comprising:
a display assembly with a display panel and a backlight arranged behind the display panel; a stabilization assembly with a cutout for accommodating the display assembly; and a decorative film, which is attached at least to a top side of the stabilization assembly and extends over the cutout for the display assembly, wherein the stabilization assembly mechanically stabilizes the decorative film, wherein the decorative film consists of two or more sheets, which each extend over the cutout for the display assembly.

5 . The display element as claimed in claim 1 , wherein the stabilization assembly is applied onto the decorative film by plastic injection molding.

6 . The display element as claimed in claim 1 , wherein the display assembly is adhesively bonded to the decorative film and/or to the stabilization assembly.

7 . The display element as claimed in claim 1 ,
wherein the display panel has a plurality of light valves configured to regulate passage of light from the backlight through the display panel, and wherein a distance between each of the plurality of light valves of the display panel and a top side of the decorative film lies in the range from 500 μm to 1000 μm.

8 . The display element as claimed in claim 1 , wherein the display element has two or more display assemblies and the stabilization assembly has two or more cutouts for accommodating the two or more display assemblies.

9 . The display element as claimed in claim 1 , wherein only the decorative film is disposed in the region of the cutout and not any supporting components.

10 . A method for producing a display element, the method comprising:
applying a decorative film onto a stabilization assembly, wherein the stabilization assembly mechanically stabilizes the decorative film; and placing at least a part of a display assembly into a cutout in the stabilization assembly, wherein a portion of the decorative film in a display region located above the display assembly is thinner than a portion of the decorative film in a peripheral region extending around the display assembly.

11 . The method as claimed in claim 10 , wherein a display panel of the display assembly is applied onto a rear side of the decorative film before the decorative film is applied onto the stabilization assembly.
