Title: DEVICE FOR FORMING AN IMAGE AND HEAD-UP DISPLAY COMPRISING A DEVICE OF THIS KIND
Abstract:
An image-forming device (2) comprises: - a beamforming module (12) using at least two sources (R, G, B) of different-coloured light to produce a polychromatic light beam; - a diffuser (18) lit up by the polychromatic light beam in such a way that an image is formed; and - a liquid crystal cell (13) capable of inducing variable polarization in the light beam, depending on a voltage (V) applied to the cell (13). A control module (10) controls the light intensity (I'R; I'G; I'B) of at least one of said sources (R; G; B) of light, depending on the voltage (V) applied. The invention also relates to a head-up display comprising a device of this type.
