Abstract:
(EN) The invention relates to an image-generating unit (10) comprising: a screen (12), by means of which an image to be displayed is generated; and a back-lighting device (11) including at least one light source (110) and an optical system (113, 114) that is configured to, from the light emitted by the source, produce a light beam (F) for lighting the screen. According to the invention, the image-generating unit furthermore comprises adjusting means (13) for modifying the orientation of the lighting light beam with respect to the screen, said adjusting means leaving said source stationary with respect to said optical system. The invention also relates to a head-up display equipped with such an image-generating unit.
(FR) L'invention concerne une unité de génération d'image (10) comprenant : - un écran (12), au moyen duquel est générée une image à afficher, et - un dispositif de rétro-éclairage (11) comportant au moins une source (1 10) de lumière ainsi qu'un système optique (1 13, 1 14) configuré pour, à partir de la lumière émise par la source, produire un faisceau lumineux d'éclairage (F) de l'écran. Selon l'invention, l'unité de génération d'image comprend en outre des moyens de réglage (13) pour modifier l'orientation du faisceau lumineux d'éclairage par rapport à l'écran, lesdits moyens de réglage laissant ladite source fixe par rapport audit système optique. L'invention concerne aussi un afficheur tête haute muni d'une telle unité de génération d'image.
