Abstract

A head-up display system for display on a windowpane includes: an image-generating display device configured to generate an image; and an optical system configured to deflect the generated image onto the windowpane. The display device is an electronic paper display

Claims

1. A head-up display system (10) for display on a windowpane (100), comprising:

an image-generating display device (2) configured to generate an image; and

an optical system (3) configured to deflect the generated image onto the windowpane (100),

wherein the display device is an electronic paper display.

2. The head-up display system as claimed in claim 1, further comprising a lighting source (4) configured to generate radiation to light the display device (2).

3. The head-up display system as claimed in claim 2, wherein the display device (2) is configured to, during operation of the head-up display system, reflect the radiation generated by the lighting source (4).

4. The head-up display system as claimed in claim 2, wherein the display device (2) is configured to, during operation of the head-up display system, transmit the radiation generated by the lighting source (4).

5. The head-up display system as claimed in claim 2, wherein the lighting source (4) is configured to be, during operation of the head-up display system, adjustable with respect to a colorimetric locus.

6. The head-up display system as claimed in claim 5, wherein the lighting source has:

light sources configured to emit light respectively in the red, green and blue spectral regions, and

a synchronization unit (6) configured to selectively actuate the respective light sources.

7. The head-up display system as claimed in claim 1, wherein the image-generating display device (2) has a curved image-generating surface (20).

8. The head-up display system as claimed in claim 7, wherein the curvature of the image-generating surface (20) is adjustable.

9. A head-up display (1) comprising:

the head-up display system (10) as claimed in claim 1; and

the windowpane (100) onto which the optical system (3) directs the image of the display device (2).

10. The head-up display (1) as claimed in claim 9, wherein the image-generating display device (2) has a curved image-generating surface (20) configured to at least partially compensate image distortion due to the windowpane.
