Head-up display providing protection against solar radiation

摘要

The system (HUD) has a combiner (3) and optical systems (2, 21) that are arranged in a manner that an image of a display device (1) is collimated. Each optical system presents lateral chromatism that is highly sufficient when solar radiation level received by the display device is lower than a determined level, where lateral chromatism of the optical system is less sufficient when dispersion of primary spectrum emitted by the display device and viewed by a user is lower than or equal to a human eye resolution limit.
