Title (EN) PROCESS FOR MANUFACTURING AN LED-BASED EMISSIVE DISPLAY DEVICE
(FR) PROCEDE DE FABRICATION D'UN DISPOSITIF D'AFFICHAGE EMISSIF A LED
Abstract:
(EN) The invention relates to a process for manufacturing an LED-based display device, including the following successive steps: a) adding, to a planar face of a carrier wafer (150) made of a transparent material, the other face of which is structured and defines a plurality of microlenses, a plurality of semiconductor chips (100), each comprising at least one LED; and b) forming a network (130) of conductive interconnect tracks making contact with the chips (100) via their face that is opposite the carrier wafer (150).
(FR) L'invention concerne un procédé de fabrication d'un dispositif d'affichage à LED, comportant les étapes successives suivantes : a) reporter, sur une face plane d'une plaque de support (150) en un matériau transparent dont l'autre face est structurée et définit une pluralité de microlentilles, une pluralité de puces semiconductrices (100) comprenant chacune au moins une LED; et b) former un réseau (130) de pistes conductrices d'interconnexion contactant les puces (100) par leur face opposée à la plaque de support (150).
