Abstract: A head-up display system includes a display device, a liquid crystal cell and a driver circuit. The display device is configured to generate multiple images at a frame rate. Each image includes multiple image segments with an initial polarization. The liquid crystal cell includes multiple addressable segments. The addressable segments are aligned with the image segments. The addressable segments are individually controllable to selectively adjust the initial polarization of the image segments between two different polarizations. The driver circuit is in communication with the display device and the liquid crystal cell. The driver circuit is configured to control the addressable segments to pass each image segment that has visible content to a user with the initial polarization switched between the two different polarizations at a frequency greater than the frame rate of the images and attenuate sunlight incident on the display device at each image segment that has blank content.

Abstract: The invention relates to a lighting unit (1) for illuminating at least one edge face of a light guide plate (9) designed to backlight a digital screen panel (11). The unit (1) has a printed circuit board (2) designed to be mounted behind the light guide plate (9), and at least one light-emitting member (3) electrically connected to the printed circuit board (2). The printed circuit board (2) has a main portion (4) designed to be mounted behind the light guide plate (9), and a secondary portion (6) extending the main portion (4) while also being angularly positioned in such a manner as to form an angle with said main portion (4) so as to be situated facing the edge face of the light guide plate (9), and the light-emitting members (3) are carried by the secondary portion (6). The invention is applicable to flat screens.

Abstract: The invention relates to a system for pre-adjusting the video image adjustment parameters of a flat screen device for displaying images, consisting of a screen and electronic control circuits which transmit video signals to it and a reticle generator. According to the present invention, the device further includes acquisition means for acquiring the video signals, means for calculating values of the adjustment parameters and adjustment means for storing the values of the adjustment parameters in the electronic control circuits.
