A display device for displaying images conveying depth information comprises a first display unit for representing first image information on a first screen. The first display unit comprises the first screen with a holographic optical element, HOE, provided thereon, and a first light source for providing light for illuminating the first screen. The display device further comprises a second display unit for representing second image information. The second display unit comprises a second light source for providing light with a plurality of predetermined discrete wavelengths for creating the second image information, and a second screen which is provided in parallel or oriented at an acute angle relative to the first screen in order to project the second image information onto the first screen and thereby generate a virtual image corresponding to the second image information behind the first screen.

Display device for displaying image information conveying depth information

A head-up display device for displaying a virtual image superimposed over a field of view to a viewer is provided. The head-up display device includes a picture generating unit having an illumination source, such as a laser, to generate a real image following a first light beam. A windshield of a vehicle engages the first light beam, either at an inclined angle or perpendicular, to reflect the first light beam away from the viewer as reflected images. A combiner disposed on the windshield including a holographic optical element steers the first light beam toward the viewer as a third light beam to present the virtual image within the field of view of the viewer. Mirrors may direct and magnify first light beam onto the combiner. A method for displaying a virtual image superimposed over a field of view to a viewer using a head-up display device is also provided.
