Abstract

A pixel comprises three adjacent sub-pixels, formed by respective stacks of semi-conducting layers wherein: each sub-pixel comprises a first active layer, adapted for emitting a light at a first wavelength when an electric current passes through it; another sub-pixel comprises a second active layer, adapted for emitting a light at a second wavelength greater than the first wavelength; another sub-pixel comprises a third active layer, adapted for emitting a light at a third wavelength greater than the first wavelength and different from the second wavelength; at least one from among the second and third active layers being adapted for emitting light when it is excited by the light at the first wavelength emitted by the first active layer of the same sub-pixel. Semi-conducting structure and methods for the fabrication of such a pixel are provided.
