COMPACT AND ENERGY-EFFICIENT HEAD-UP DISPLAY

摘要

The invention relates to a head-up display comprising a group of optical sub-systems (261, 262, 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.

主权项

1. A head-up display comprising an assembly of optical sub-systems formed in a same plane and having their focal distance increasing along with the distance from the main optical axis of the display, further comprising sub-screens having their positions and dimensions defined according to the length of the optical path, to the focal distances of the optical sub-systems, and to a maximum authorized motion length in a plane perpendicular to the optical axis and located at a distance equal to the length of the optical path, so that the formation projected by the assembly of sub-screens can be seen over the entire authorized motion amplitude.
