Abstract

The emissive device includes first and second adjacent pixels (1a, 1b) sharing a common semiconductor light-emitting stack (2) and each defining an area (4a, 4b) of photon emission. The first and second pixels (1a, 1b) are configured in such a way that supplying current to the first pixel (1a) causes photons to be emitted, by the light-emitting stack (2), only in the emission area (4a) of said first pixel (1a).
