Abstract (en)
[origin: WO2017191053A1] 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.
