Title (EN) DEVICE FOR GENERATING A MULTICOLOUR IMAGE AND HEADS-UP DISPLAY INCLUDING SUCH A DEVICE
(FR) DISPOSITIF DE GÉNÉRATION D'UNE IMAGE MULTICOLORE ET AFFICHEUR TÊTE-HAUTE COMPORTANT UN TEL DISPOSITIF
Abstract: front page image
(EN)The invention relates to a device (30) for generating a multicolour image made up of a set of pixels (4) including light sources (31, 32, 33), a control unit (20) activating, for a given pixel of the image, each source at respective activation times (tB, tV, tR), each activated source emitting a source light beam (11, 12, 13) with an emission wavelength (λ0,B, λ0,V, A0,R), a first optical system (34, 35, 36) directing the source beams towards diversion means (50) diverting each source beam in a diversion direction (θ1, θ2, θ3), and a diffusion module (40) intercepting each diverted source beam (71, 72, 73) in order to generate a diffused light beam (7). According to the invention, the control unit activates the sources at activation times that are offset in time so that the source beams are diverted in diversion directions that are offset at an angle.
(FR)L'invention concerne un dispositif (30) de génération d'une image multicolore formée d'un ensemble de pixels (4) comportant des sources lumineuses (31, 32, 33), une unité de commande (20) activant, pour un pixel donné de l'image, chaque source à des instants d'activation (tB, tV, tR) respectifs, chaque source activée émettant un faisceau lumineux source (11, 12, 13) à une longueur d'onde d'émission (λ0,B, λ0,V, λ0,R), un premier système optique (34, 35, 36) dirigeant les faisceaux sources vers des moyens de déviation (50) déviant chaque faisceau source dans une direction de déviation (θ1, θ2, θ3), et un module de diffusion (40) interceptant chaque faisceau source dévié (71, 72, 73) pour générer un faisceau lumineux diffusé (7). Selon l'invention, l'unité de commande active les sources à des instants d'activation décalés temporellement de sorte que les faisceaux sources sont déviés dans des directions de déviation décalées angulairement.
