    Abstract: The invention relates to a system for controlling the luminosity of a head-up display (36) of a vehicle, said display (36) being configured to display an image, said system comprising means (32) for assessing luminosity connected to means (34) for determining a luminosity instruction for the display (36). The system is characterized in that said means (32) for assessing luminosity are capable of assessing the external luminosity towards the front of the vehicle and beyond the image displayed on said display (36), and in that said determination means (34) are capable of determining the luminosity instruction in accordance with the external luminosity assessed and of transmitting same to the display (36).

    Abstract: The invention relates to a projection system for a display, in particular a heads-up display, comprising a liquid crystal screen (12) and a back-lighting device (14) for said screen (12). The projection system is characterised in that said back-lighting device (14) comprises at least one light source (16) emitting light towards the screen (12), at least one lens (38a, 38b) suitable for collimating the light from the light source (16) towards the liquid-crystal screen (12), and reflective means (26) arranged on the surface of the lens (38a, 38b) located on the side of the light source (16), arranged such as to allow light to pass through same towards the screen (12) and to reflect towards the screen (12) almost all of the light propagating towards the lens (38a, 38b).

    Abstract: One subject of the invention is a light guide (13), for an interface module, in particular for a vehicle passenger compartment, for emitting or receiving a light beam in a cone that is elongate in a transverse direction and that is centred on a plane that is inclined by an angle θ with respect to an optical axis (z) of the light guide, taking the form of a prism made of transparent material of index nGL, characterised in that it comprises: •an interior dioptric interface intended to face a printed circuit board (7) bearing a light source (5) or a light detector, forming a convergent lens the focal point of which is located at an expected position of the light source (5) or of the light detector, •a first planar face (15) that is oriented parallel to the optical axis (z) of the light guide, and •a second planar face (17) that is inclined with respect to the first face (15) by an angle α respecting cos(α+θ)=(1−ε) nGL*cos 3α, with ε a number comprised between −0.1 and 0.1.

    Abstract: A compact head-up display for a vehicle includes: an image generator that displays an image on a display surface, and a semi-reflecting optical element, arranged at a distance from the image generator, that forms, on a first side of the optical element, a virtual image. The virtual image is visible from a viewing window on a second side of the optical element. The display includes an optical component that lengthens the optical path of the image passing from the image generator to the optical element. The optical component includes one entry face and one exit face, and a first reflecting face and a second reflecting face. The first reflecting face reflects the image from the entry face toward the second reflecting face. The second reflecting face reflects the image from the first reflecting face toward the exit face. The entry face is in contact with the display surface.
