Abstract

A system for projecting images, configured to implement a sequential type colour projection. The system includes an emissive matrix display device; and a wavelength conversion coloration wheel. The coloration wheel includes a transparent zone, and a first photoluminescent zone configured to absorb a blue light beam and to emit in response a beam including a green component and a red component. The system further includes a selection device for blocking alternately the green component or the red component, including at least one dichroic mirror.
