Title
(DE) LED-ELEMENT, LED-TAFEL UND LED-ANZEIGESCHIRM
(EN) LED COMPONENT, LED PANEL AND LED DISPLAY SCREEN
(FR) COMPOSANT DEL, PANNEAU À DEL ET ÉCRAN D'AFFICHAGE À DEL
Abstract
(EN) The LED pixel includes a driver IC (20) and an LED chip (40); the LED chip (40) is stacked and mounted on a surface of the driver IC (20), and a wire (31) going from the cathode of the LED chip (40) is connected to the driver IC (20). The driver IC (20) is an unpackaged die. An insulation layer is disposed on the surface of the die, and a pad (30) disposed on the insulation layer is connected to a positive electrode. The LED chip (40) is mounted on the pad (30), and the anode of the LED chip (40) is electrically connected with the pad (40). This improves the light transmittance of the LED display product.
(FR) On décrit un point de pixel DEL comprenant un CI de commande (20) et une puce DEL (40). La puce DEL (40) est empilée et montée sur la surface du CI de commande (20); un fil (31) conduit à l'extérieur depuis une électrode négative de la puce DEL (40) est raccordé au CI de commande (20); et le CI de commande (20) est une puce nue non encapsulée. La surface de la puce nue est munie d'une couche d'isolation; un plot de connexion (30) connecté à une électrode positive est ménagé au-dessus de la couche d'isolation; la puce DEL (40) est montée sur le plot de connexion (30); et l'électrode positive de la puce DEL (40) est raccordée électriquement au plot de connexion (30). La transmittance de la lumière d'un produit d'affichage DEL s'en trouve améliorée.
