The invention relates to a display () comprising&#x2014;a casing (), &#x2014;an image generation unit (), and&#x2014;a light sensor (), disposed in the interior (INT) of said casing (), suitable for delivering a signal representative of a light intensity received by same, the display () being adapted such that the luminosity of an image generated by the image generation unit () is controlled as a function of said signal. According to the invention, the display () further comprises a light guide () situated in the interior (INT) of the casing () of the display (), having an inlet face () and being shaped to collect at the input face () of same a light ray coming from outside the casing () of the display, and for guiding said light ray to said sensor ().

Display comprising a light sensor

The invention relates to an active screen (), i.e. to a light-emitting screen, comprising a matrix array of modules () that each form one pixel, and a matrix array () of control elements that are intended to address each of these modules, respectively. According to the invention, each module comprises at least three light-emitting submodules () that each include a three-dimensional light-emitting structure (), and each control element is intended to individually address each submodule. A head-up display () comprising such a screen (), and a device () for projecting images, said device being suitable for transmitting, in the direction of a semitransparent mirror () the images generated by said screen, is also described.

Active screen and head-up display comprising such a screen

An image generating device () comprises a liquid-crystal screen () and a light source (). The liquid-crystal screen () comprises a matrix of liquid crystals interposed between an input polariser and an output polariser. The image generating device () comprises a first additional polariser () located on the light path, upstream of said liquid-crystal screen (), and a second additional polariser () located on the light path, downstream of said liquid-crystal screen (). The invention also relates to a head-up display () comprising a device () of this type.

Image generating device and head-up display

The invention relates to a display () comprising: an image generation unit comprising at least one light emitter (), a printed circuit support plate (), on which said emitter () is mounted, and a light sensor () capable of delivering a signal representative of a light intensity received by same, the display () being adapted in such a way that the luminosity of an image generated by the image generation unit is controlled as a function of said signal. According to invention, the light sensor () is mounted on said printed circuit support plate ().
