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;

    a lighting source (4) configured to generate radiation to light the image-generating display device (2);

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

    a time-division multiplexer (5) configured to feed color information to the lighting source (4) in a ratio of 3;

    1,wherein the lighting source includes;

    first, second and third light sources configured to emit light, respectively in the red, green and blue spectral regions, anda synchronization unit (6) configured to synchronize the display device (2) to selectively actuate respective ones of the first, second and third light sources for display of a full-color image, andwherein the image-generating display device (2) is an electronic paper display device on a flexible substrate, the electronic paper display device including a curved image-generating surface (20) having a curvature, the curvature of the image-generating surface (20) being adjustable, during initialization and during normal operation of the display device (2), by mechanical or electromechanical components configured to adjust the curvature of the image-generating surface (20) so as to compensate for image distortion occurring due to a curvature of the windowpane.
