  • Colour projector with spectral conversion coloration wheel
    Patent number: 11036124
    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.
    Type: Grant

  • Colour projector with two emissive displays
    Patent number: 10955735
    Abstract: The invention relates to an image projection system (200) configured to implement colour projection comprising: a first matrix device (210) with an emissive display for transmitting a first and a second colour component of a colour image, wherein each pixel is adapted to transmit at the wavelengths associated with the first colour component and the wavelengths associated with the second colour component; and a second matrix device (220) with an emissive display for transmitting a third colour component (221) of the colour image. The colour image projector according to the invention offers both good energy efficiency and a small footprint.
