Abstract
A method of manufacturing an emissive screen comprising LEDs, including the steps of: a) depositing a first metal layer on a surface of a control circuit; b) depositing a second metal layer on a surface of an optoelectronic circuit; c) bonding the optoelectronic circuit to the control circuit by direct bonding of the second metal layer to the first metal layer, by aligning the optoelectronic circuit with respect to the control circuit so that different emission cells of the optoelectronic circuit are arranged opposite different metal connection pads of the control circuit; and d) forming, from the surface of the optoelectronic circuit opposite to the control circuit, trenches laterally delimiting each emission cell.
