Abstract
Official abstract text for this publication.
The present disclosure relates to a display device and to a means of transportation having such a display device. The display device comprises a display panel and a backlight for the display panel. The backlight comprises a reflector having a multiplicity of reflectively configured cavities. In addition, the backlight comprises a multiplicity of light sources arranged in each case in the cavities. Walls of the cavities are configured such that a grid structure of the reflector resulting from the arrangement of the cavities is broken up.
First claim
Opening claim text (preview).
The invention claimed is: 1. A display device comprising a display panel and a backlight for the display panel, the backlight comprising: a reflector having a multiplicity of reflectively configured cavities, with walls of the cavities being configured such that a grid structure of the reflector resulting from the arrangement of the cavities is broken up, wherein upper edges of the cavities as viewed by an observer form irregular pentagons, hexagons, or a curved profile; and a multiplicity of light sources arranged in each case in the cavities. 2. The display device as claimed in claim 1 , wherein adjacent cavities each have a different configuration. 3. The display device as claimed in claim 1 , wherein the cavities are nested in one another. 4. The display device as claimed in claim 1 , wherein the light sources have a regular arrangement. 5. The display device as claimed in claim 1 , wherein the walls of the cavities are rounded and the cavities are configured to reflect the light emitted by the light sources toward the display panel. 6. The display device as claimed in claim 5 , wherein the light sources are side-emitting light-emitting diodes. 7. The display device as claimed in claim 6 , wherein the side-emitting light-emitting diodes emit light on all sides. 8. A motor vehicle comprising a display device comprising a display panel and a backlight for the display panel, the backlight comprising: a reflector having a multiplicity of reflectively configured cavities, with walls of the cavities being configured such that a grid structure of the reflector resulting from the arrangement of the cavities is broken up, wherein upper edges of the cavities as viewed by an observer form irregular pentagons, hexagons, or a curved profile; and a multiplicity of light sources arranged in each case in the cavities.
