Abstract

Claims (28)

1. A display system, comprising:

a display configured for displaying data, wherein the display comprises an inactive display edge not configured for displaying, and an active display inner surface configured for displaying;

a backlighting module having luminous units, wherein the backlighting module is arranged directly or indirectly at a rear side of the display, such that the light emitted by the luminous units forms a backlight for the display, wherein the backlighting module comprises a backlighting edge corresponding to the display edge and a backlighting inner surface corresponding to the display inner surface, wherein a transition edge region extends from the backlighting edge over a portion of the backlighting inner surface, wherein a first number of individually drivable luminous units are arranged in the transition edge region, wherein the backlighting inner surface without the transition edge region comprises a second number of individually drivable luminous units, and wherein the first number is higher than the second number; and

a control system for driving the luminous units.

2. The display system according to claim 1 , wherein the control system is configured to drive the luminous units arranged in the transition edge region individually or with said luminous units interconnected in first clusters, and to drive the luminous units comprised by the backlighting inner surface without the transition edge region with said luminous units interconnected in second clusters, wherein the number of interconnected luminous units in the first cluster is lower than the number of interconnected luminous units in the second cluster.

3. The display system according to claim 1 , wherein the display is configured as a liquid crystal display.

4. The display system according to claim 1 , wherein the luminous units in the transition edge region are arranged in a matrix-shaped fashion.

5. The display system according to claim 1 , wherein the luminous units in the backlighting inner surface without the transition edge region are arranged in a matrix-shaped fashion.

6. The display system according to claim 2 , wherein no luminous units, or in comparison with the transition edge region and the backlighting inner surface without the transition edge region, a reduced number of luminous units are arranged in the backlighting edge.

7. The display system according to claim 2 , wherein the display inner surface comprises non-visible regions and no luminous units are arranged in the backlighting inner surface corresponding to said regions.

8. The display system according to claim 2 , wherein the display inner surface comprises non-visible regions and a reduced number of luminous units are arranged in the backlighting inner surface corresponding to said regions.

9. The display system according to claim 2 , wherein the luminous units are configured as light emitting diodes.

10. The display system as claimed in claim 9 , wherein the light emitting diodes are designed to be individually dimmable.

11. A vehicle, comprising:

a display system, comprising:

a display configured for displaying data, wherein the display comprises an inactive display edge not configured for displaying, and an active display inner surface configured for displaying;

a backlighting module having luminous units, wherein the backlighting module is arranged directly or indirectly at a rear side of the display, such that the light emitted by the luminous units forms a backlight for the display, wherein the backlighting module comprises a backlighting edge corresponding to the display edge and a backlighting inner surface corresponding to the display inner surface, wherein a transition edge portion extends from the backlighting edge over a portion of the backlighting inner surface, wherein a first number of individually drivable luminous units are arranged in the transition edge region, wherein the backlighting inner surface without the transition edge region comprises a second number of individually drivable luminous units, and wherein the first number is higher than the second number; and

a control system for driving the luminous units.

12. The display system according to claim 11 , wherein the control system is configured to drive the luminous units arranged in the transition edge region individually or with said luminous units interconnected in first clusters, and to drive the luminous units comprised by the backlighting inner surface without the transition edge region with said luminous units interconnected in second clusters, wherein the number of interconnected luminous units in the first cluster is lower than the number of interconnected luminous units in the second cluster.

13. A method for operating a display system, comprising:

providing a display configured for displaying data, wherein the display comprises an inactive display edge not configured for displaying, and an active display inner surface configured for displaying;

providing a backlighting module having luminous units, wherein the backlighting module is arranged directly or indirectly at a rear side of the display, such that the light emitted by the luminous units forms a backlight for the display, and wherein the backlighting module comprises a backlighting edge corresponding to the display edge and comprises a backlighting inner surface corresponding to the display inner surface;

providing a control system for driving the luminous units;

providing a transition edge region extending from the backlighting edge over a portion of the backlighting inner surface;

operating a first number of individually driveable luminous units arranged in the transition edge region; and

operating a second number of individually driveable luminous units arranged in the backlighting inner surface-without the transition edge region, wherein the first number is higher than the second number.

14. The method according to claim 13 , wherein the method further comprises driving luminous units individually or with said luminous units interconnected in first clusters, which are arranged in the transition edge region, and interconnected in second clusters, which are arranged in the backlighting inner surface without the transition edge region, wherein the number of interconnected luminous units in the first cluster is lower than the number of interconnected luminous units in the second cluster.

15. The method according to claim 14 , wherein no luminous units or, in comparison with the transition edge region and the backlighting inner surface without the transition edge region, a reduced number of luminous units are arranged in the backlighting edge.
