Abstract

A display device for a motor vehicle, e.g., an instrument cluster, includes at least one first display device emitting image-forming light, and at least one illuminated and/or self-luminous electromechanical second display device. The first display device is arranged in a visual field of an observer. The second electromechanical display device is arranged at an angle to the first display device, and a combination element is provided between the first display device and the electromechanical display device, the combination device being transparent to the image-forming light in the first display device and reflective to the image-forming light of the electromechanical second display device.

Claims

1-16. -16. (canceled)

17. A display device for a motor vehicle, comprising:

at least one first display device adapted to emit image-forming light, the first display device arranged in a visual field of an observer;

at least one of (a) an illuminated and (b) a self-luminous electromechanical second display device, the first display device and the second display device arranged at an angle to each other; and

a combination device arranged between the first display device and the second display device, the combination device transparent to the image-forming light of the first display device and reflective to image-forming light of the second display device.

18. The display device according to claim 17, wherein the display device is arranged as a instrument cluster of the motor vehicle.

19. The display device according to claim 17, wherein the second display device includes at least one pointer instrument.

20. The display device according to claim 17, wherein a sum of reflections of the image-forming light of the first display device and the image-forming light of the second display device is at most 4.

21. The display device according to claim 17, wherein a sum of reflections of the image-forming light of the first display device and the image-forming light of the second display device is at most 2.

22. The display device according to claim 17, wherein the angle is formed by a center axis of the first display device and the second display device.

23. The display device according to claim 17, wherein at least a display-effective area of at least one of (a) the second display device and (b) the combination device is arranged at a distance from the first display device.

24. The display device according to claim 17, wherein the angle is less than 180°

.

25. The display device according to claim 17, wherein the angle is between 75°

and 120°

.

26. The display device according to claim 17, wherein the angle is 90°

.

27. The display device according to claim 17, wherein the combination device is adapted to halve the angle between the first display device and the second display device.

28. The display device according to claim 17, wherein the combination device includes a partially transparent mirror transparent to the image-forming light of the first display device and reflective to the image-forming light of the second display device.

29. The display device according to claim 17, wherein in at least one display mode, a display image of the display device is at least one of (a) formable and (b) formed by a display image of the first display device and by the image-forming light of the second display device.

30. The display device according to claim 17, wherein in at least one display mode, the image-forming light of the second display device forms at least one dial instrument.

31. The display device according to claim 17, wherein in at least one display mode, the image-forming light of the second display device forms at least one dial instrument having an at least partial pointer presentation.

32. The display device according to claim 30, wherein in a display image of the display device, a representation of the at least one dial instrument appears to be optically arranged virtually in front of the display image of the display device.

33. The display device according to claim 17, wherein in at least one display mode, at least one part of the second display device is at least one of (a) able to be illuminated, (b) illuminated, (c) able to be activated and (d) activated.

34. The display device according to claim 17, wherein the second display device includes at least one of (a) controllable warning displays, (b) luminous area displays and (c) warning lights.

35. The display device according to claim 17, wherein the second display device includes at least one first measured quantity display arranged in a main area of the second display device and includes at least one second display for the same measured quantity arranged in a lateral area of the second display device, in at least one display mode, image-forming light of the first measured quantity display at least one of (a) reflectable and (b) reflected by the combination device, in at least one additional display mode, image-forming light of the second display of the same measured quantity at least one of (a) reflectable and (b) reflected by the combination device.

36. The display device according to claim 35, wherein the first measured quantity display includes at least one of (a) a first speed display and (b) a dial instrument.

37. The display device according to claim 35, wherein the second display includes at least one of (a) a second speed display and (b) a dial instrument.

38. The display device according to claim 35, wherein the second display of the measured quantity is smaller than the first measured quantity display.

39. The display device according to claim 35, wherein the second display of the measured quantity is at most ¾

of a size of the first measured quantity display.

40. The display device according to claim 35, wherein the second display of the measured quantity is at most ½

of a size of the first measured quantity display.

41. The display device according to claim 35, wherein in the at least one display mode, in an area of the first measured quantity display, one of (a) substantially only and (b) only a display image of the first display device is at least one of (a) showable and (b) shown on the display device.
