Abstract

Claims (18)

1. A display device comprising a display panel and a backlight for the display panel, wherein the backlight comprises:

a reflector with a plurality of reflectively embodied cavities wherein the height of the reflector is about 3.72 mm;

a plurality of light sources arranged in each of the cavities;

support elements, which are transparent to light emitted by the light sources; and

a gap between the cavities and an optical component arranged below the display panel, wherein the support elements protrude at least partially into the gap between the cavities and the optical component arranged below the display panel, wherein the support elements are placed on walls of the cavities or are incorporated in walls of the cavities but do not contact the optical component, and prevent the display panel from breaking in a case of a head impact.

2. The display device as claimed in claim 1 , wherein the support elements are supported on a circuit board, on which the light sources are arranged.

3. The display device as claimed in claim 1 , wherein walls of the cavities are rounded and the cavities are designed to reflect the light emitted by the light sources in the direction of the display panel.

4. The display device as claimed in claim 3 , wherein the light sources are side-emitting light-emitting diodes.

5. The display device as claimed in claim 4 , wherein the side-emitting light emitting diodes emit light on vertical sides.

6. The display device as claimed in claim 1 , wherein the cavities form a rectangular grid or a hexagonal grid.

7. The display device as claimed in claim 1 , wherein the support elements are formed from polycarbonate or polymethyl methacrylate.

8. A motor vehicle, comprising:

a display device comprising a display panel and a backlight for the display panel, wherein

the backlight comprises:

a reflector with a plurality of reflectively embodied cavities wherein the height of the reflector is about 3.72 mm;

a plurality of light sources arranged in each of the cavities;

support elements, which are transparent to light emitted by the light sources; and

a gap between the cavities and an optical component arranged below the display panel, wherein the support elements protrude at least partially into the gap between the cavities and the optical component arranged below the display panel, wherein the support elements are placed on walls of the cavities or are incorporated in walls of the cavities but do not contact the optical component, and prevent the display panel from breaking in a case of a head impact.
