Abstract
The general field of the invention is that of head-up display systems HUD, protected from solar illumination. An HUD includes at least one display, an optical system and at least one semi-reflecting plate called a combiner, said optical system and said combiner being arranged so that the image on the display is collimated, the display emitting in at least one first optical spectrum of first spectral width, the display being arranged so as to withstand illumination of a predetermined level. In the display according to the invention, the lateral chromatism of the optical system is sufficiently strong for the level of solar illumination received by the display to be always less than said predetermined level and said lateral chromatism is sufficiently weak for the dispersion of the first spectrum emitted by the display and seen by a user to be less than or equal to the resolution limit of the human eye.
