Abstract (en)
[origin: WO2013178925A2] The invention relates to a head-up display comprising a group of optical sub-systems (261, 26 2 , 263) formed in a single plane and having focal lengths that increases moving away from the main optical axis of the display. The display also comprises sub-screens (241, 242, 243), the positions and dimensions of which are defined according to: the length of the optical path (D), the focal lengths of the optical sub-systems, and a maximum authorised length of movement in a plane perpendicular to the optical axis and located at a distance equal to the length of the optical path, such that the information projected by the group of sub-screens can be seen along the entire authorised length of movement.
