Abstract[English]
The present invention solves issues with microLED displays that use phosphors. A method to protect phosphor functionality in microLED displays during lamination includes depositing a protective bank with a transparent material before a phosphor coating. The method further includes having the protective bank acting as a barrier, so a top of the phosphor is below a top of the protective bank.[French]
La présente invention résout des problèmes associés à des dispositifs d'affichage à micro-DEL qui utilisent des luminophores. Un procédé pour garantir le fonctionnement de luminophores dans des dispositifs d'affichage à micro-DEL pendant la stratification consiste à déposer un élément de protection surélevé constitué d'un matériau transparent avant l'application d'un revêtement de luminophore. Selon le procédé, l'élément de protection surélevé agit comme une barrière, de telle sorte qu'une partie supérieure du luminophore est au-dessous d'une partie supérieure de l'élément de protection surélevé.
