Title (EN) MICRO LIGHT-EMITTING DIODE DISPLAY WITH 3D ORIFICE PLATING AND LIGHT FILTERING
(FR) AFFICHAGE À MICRO-DIODES ÉLECTROLUMINESCENTES AVEC PLACAGE D'ORIFICE 3D ET FILTRAGE DE LUMIÈRE
Abstract:
(EN) A micro light-emitting diode (LED) display assembly includes a backplane, a passivation layer on the backplane, a micro LED on the passivation layer, and a non-transparent metal housing on the passivation layer, wherein the housing includes a base portion on the passivation layer, a sidewall portion upwardly extending from the base portion, a cap portion connected at a top of the sidewall portion, an orifice in the cap portion, and a notch in the cap portion and adjacent to the orifice. The assembly also includes a translucent filter positioned in the notch and covering the orifice, and a pocket defined by an enclosed area in between the sidewall portion, the cap portion, the filter, and the passivation layer, wherein the micro LED is encased within the pocket such that light transmitted from the micro LED directly hits and passes through the filter.
(FR) L'invention concerne un ensemble d'affichage à micro-diodes électroluminescentes (DEL) comprenant un fond de panier, une couche de passivation sur le fond de panier, une micro-DEL sur la couche de passivation, et un boîtier métallique non transparent sur la couche de passivation, le boîtier comprenant une partie de base sur la couche de passivation, une partie de paroi latérale s'étendant vers le haut à partir de la partie de base, une partie de capuchon reliée au sommet de la partie de paroi latérale, un orifice dans la partie de capuchon, et une encoche dans la partie de capuchon et adjacente à l'orifice. L'ensemble comprend également un filtre translucide positionné dans l'encoche et recouvrant l'orifice, et une poche définie par une zone fermée entre la partie de paroi latérale, la partie capuchon, le filtre et la couche de passivation, la micro-DEL étant enfermée à l'intérieur de la poche de telle sorte que la lumière transmise à partir de la micro-DEL frappe et passe directement à travers le filtre.
