Abstract

The invention relates to an illuminable display element, in particular for a vehicle, which display element comprises a planar cover (1). The planar cover has a visible side (10), a rear side (11), and at least one opening (14). The display element also comprises at least one graphic element (2), which is provided and/or formed on the visible side (10) of the cover (1), and a lighting means (3), which is used to illuminate the opening (14). The graphic element (2) is at least partially surrounded by the at least one opening (14) in such a way the graphic element (2) can be at least partially peripherally illuminated by the light of the lighting means (3). The cover (1) comprises at least one elevation (12) extending upward, within which the graphic element (2) is arranged above the at least one opening (14), and/or the cover (1) comprises at least one recess (13) extending downward, within which the graphic element (2) is arranged below the at least one opening (14).

Claims17

Dependent claims

An illuminable display element, in particular for a vehicle, comprising:

a first layer comprising a two-dimensionally extending cover formed overall in one piece and comprising a visible side, a rear side and at least one through-hole;
at least one graphical element which is provided and/or formed on the visible side of the cover;
a lighting element which is used to illuminate the through-hole;
a second layer comprising a carrier layer which is disposed on the rear side of the cover at least in the region of the at least one through-hole;
a third layer comprising at least one film which is a separate structure disposed between the carrier layer and the cover and which is disposed on the rear side of the cover in such a way that the at least one film extends at least partially into the at least one through-hole;
and
wherein the graphical element is at least partially enclosed by the at least one through-hole in such a way that light from the lighting element can at least partly shine around the graphical element,
wherein the cover has at least one elevation extending upward, within which the graphical element is arranged above the at least one through-hole, and/or wherein the cover has at least one depression extending downward, within which the graphical element is arranged below the at least one through-hole,
wherein the first, second and third layers are separate layers,
wherein the carrier layer and the at least one film are configured to be optically transparent at least in regions, in order to form a light guide, which is used to guide light emitted by the lighting element to the at least one through-hole, and
wherein the carrier layer and the at least one film extends from the rear side of the cover around an edge at an opening of the through hole and into the at least one through-hole.

8 more elements

A method for producing an illuminable display element having a graphical element comprising at least the following steps:

providing a first layer comprising a two-dimensionally extending cover formed overall in one piece and having a visible side and a rear side;
forming at least one elevation extending upward and/or at least one depression extending downward in the cover by means of shaping the cover;
and
forming at least one through-hole in the cover;
applying a second layer comprising a carrier layer on the rear side of the cover at least in the region of the at least one through-hole;
applying third layer comprising a at least one film on the rear side of the cover between the carrier layer and the cover and at least in the region of the at least one through-hole in such a way that the at least one film extends at least partially into the at least one through-hole;
wherein the carrier layer and the at least one film are configured to be optically transparent at least in regions, in order to form a light guide, which is used to guide light emitted by a lighting element to the at least one through-hole,
wherein the elevation and/or the depression are configured and/or arranged in such a way that the graphical element is arranged within the elevation or depression,
wherein the first, second and third layers are separately formed;
wherein the graphical element and the at least one through-hole are arranged and configured with respect to one another in such a way that the at least one through-hole is arranged below the graphical element in the case of an elevation and above the graphical element in the case of a depression, and at least partially encloses this element, and
wherein the carrier layer and the at least one film are applied on the rear side of the cover such that the carrier layer and the at least one film extends from the rear side of the cover around an edge at an opening of the through hole and into the at least one through-hole.
