HEAD-UP DISPLAY HAVING A PLURALITY OF PROJECTION PLANES
A head-up display in a motor vehicle has an imaging unit that generates images, and an optical device. The optical device projects the images into at least two projection surfaces, which in each case have a different distance from the eye of an observer.
1 . A head-up display comprising:
an imaging unit which generates images, and
an optical device,
wherein the optical device projects the images into at least two projection surfaces, which in each case have a different distance from an eye of an observer.
2 . The head-up display as claimed in claim 1 , wherein at least one projection surface is a virtual projection surface.
3 . The head-up display as claimed in claim 1 , wherein the projection surfaces are arranged one behind another.
4 . The head-up display as claimed in claim 3 , wherein the distance between the projection surfaces is 1.6-2.4 m.
5 . The head-up display as claimed in claim 1 , wherein the images displayed on the projection surfaces together produce a 3D image.
6 . The head-up display as claimed in claim 1 , wherein the information content of the images displayed on the projection surfaces are independent of one another.
7 . The head-up display as claimed in claim 1 , wherein information items are displayed on the projection surfaces simultaneously or successively.
8 . The head-up display as claimed in claim 1 , wherein it has two imaging units.
9 . The head-up display as claimed in claim 1 , wherein the optical device has at least one movable part.
