(54) MICRO-OPTICAL COMPONENT FOR GENERATING AN IMAGE


(57) The present invention concerns a micro-optical component (100) for generating an image, comprising:
- a substrate (20), comprising a first surface (21) and a second surface (22), wherein the first surface (21) comprises an aperture (12), and the second surface (22) is arranged to be connected to pixel array (300),
- a lens (10; 10'), placed on the first surface (21) so as to cover the aperture (12), the focal point of the lens (10; 10') belonging to the second surface (22).
The lens (10; 10') comprises an obscuration element generating at the lens an obscured area (40) and an unobscured area (50), wherein the obscuration element is dimensioned to reduce the light transmittance towards the pixels for a fraction of the viewing angles only and at the same time, the obscured area is dimensioned so that the optical resolution of the lines is not smaller than the image resolution given by the size of the pixels.
