Abstract
Official abstract text for this publication.
The invention relates to a head-up display comprising a group of sub-screens ( 24 1 , 24 2 , . . . 24 5 ) the positions and dimensions of which are defined according to the length of the optical path (D) and the maximum authorized range of movement (B 1 ) in a plane that is perpendicular to the optical path and located at a distance equal to the length of the optical path, such that information projected by the group of sub-screens is seen over the entire authorized movement range.
First claim
Opening claim text (preview).
The invention claimed is: 1. A head-up display comprising an assembly of sub-screens defining together an image to be displayed, each sub-screen being associated with an optical sub-system, the sub-screens being placed in the object focal plane of the optical sub-systems, the sub-screens being defined at the surface of a substrate and being separate, each sub-screen having an extension smaller than that of the associated optical sub-system, the positions and the dimensions of the s…
