Abstract
A display unit for binocular representation of a multicolor image including a control unit triggering an imaging element such that the imaging element generates in a temporal successive manner the image to be displayed for a first beam path and a second beam path as a first image and second image, respectively. The images are generated in a pre-distorted manner, opposite of the chromatic aberration of the respective beam path, such that the chromatic aberration generated in the respective beam path is compensated when the first and second image is displayed. The display unit includes a switching module which operates in temporal synchrony with the first and second image being generated, such that a user can see the first image only via the first beam path and the second image only via the second beam path.

15. A display unit for binocular representation of a multicolor image, comprising:
-
a single imaging element, by which the multicolor image that is to be represented is generated; a projection lens system including a collimation lens; a transparent substrate located after the collimation lens including a diffractive injection element and a first and a second diffractive extraction elements arranged at a distance from each other; a control unit coupled to and triggering the imaging element; the display unit defining a first beam path which extends from the imaging element to the first extraction element via the collimation lens and the injection element through the substrate, and via the first extraction element out of the substrate, and a second beam path that extends from the imaging element to the second extraction element via the collimation lens and the injection element through the substrate, and via the second extraction element out of the substrate, with different chromatic aberrations being generated in the first and second beam path because of the injection element and the first and second extraction elements; wherein the control unit triggers the imaging element such that the imaging element generates in a temporal successive manner the image to be displayed for the first beam path and the second beam path as a first image and second image, respectively, in a pre-distorted manner, opposite of the chromatic aberration of the respective beam path, such that the chromatic aberration generated in the respective beam path is compensated when the first and second image is displayed; and wherein the display unit further comprises a switching module the operates in temporal synchrony with the first and second image being generated such that a user can see the first image only via the first beam path and the second image only via the second beam path. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A displaying method for binocular representation of a multicolor image for a display unit, comprising:
-
utilizing a display unit comprising a single imaging element, by which the multicolor image that is to be represented is generated; a projection lens system including a collimation lens; a transparent substrate located after the collimation lens including a diffractive injection element and a first and a second diffractive extraction elements arranged at a distance from each other; a control unit coupled to and triggering the imaging element; the display unit defining a first beam path which extends from the imaging element to the first extraction element via the collimation lens and the injection element through the substrate, and via the first extraction element out of the substrate, and a second beam path that extends from the imaging element to the second extraction element via the collimation lens and the injection element through the substrate, and via the second extraction element out of the substrate, with different chromatic aberrations being generated in the first and second beam path because of the injection element and the extraction elements; triggering the imaging element to generate the image to be displayed for the first beam path and the second beam path in temporal succession as a first image and second image, respectively, in a pre-distorted manner that is opposite of the chromatic aberration of the respective beam path such that the chromatic aberration generated in the respective beam path is compensated when the first and second image is displayed, and temporally synchronizing with the first and second image being generated, such that a user can see the first image only via the first beam path and the second image only via the second beam path. - View Dependent Claims (23, 24, 25, 26, 27, 28)
