Methods and systems for providing an electrically dimmable combiner optics for head-up displays are disclosed. In one embodiment, a dimmable head-up display (400) includes a display portion (408) configured to provide head-up display information to an operator (402). Additionally, a dimmable portion (406) is coupled to the display portion configured to change a transmissivity of the display portion from a first transmissivity level to a second transmissivity level. The dimmable portion (406) includes a plurality of dimmable segments of independent variable transmissivity. The head-up display (HUD) may include a light sensor (412, 414) to detect the light intensity of the environment surrounding the dimmable combiner (116).

La présente invention se rapporte à des procédés et à des systèmes qui sont aptes à fournir un élément optique de combineur réglable électriquement en intensité, pour affichage à tête haute. Dans un mode de réalisation, un affichage à tête haute réglable en intensité comprend une section d'affichage qui est configurée de façon à fournir des informations affichées à tête haute à un opérateur. De plus, une section réglable en intensité est couplée à la section d'affichage, et est configurée de façon à modifier une transmissivité de la section d'affichage, depuis un premier niveau de transmissivité à un second niveau de transmissivité.
