Abstract
(EN)
A display panel is disclosed, the display array including: a substrate; a functional layer on the substrate having a plurality of recesses, at least one of the recesses in a sub-pixel region forming a well structure with a sidewall formed of the functional layer and a bottom formed of the substrate; and a plurality of micro light emitting diodes (Micro LEDs) for emitting light, at least one of the Micro LEDs within a corresponding recess; wherein the functional layer is configured to prevent at least part of the light emitted by one of the Micro LEDs and incident on the sidewall of the corresponding recess from being subsequently emitted through an adjacent sub-pixel region.

L'invention concerne un écran d'affichage, le réseau d'affichage comprenant : un substrat; une couche fonctionnelle sur le substrat comportant une pluralité d'évidements, au moins l'un des évidements dans une région de sous-pixel formant une structure de puits avec une paroi latérale formée à partir de la couche fonctionnelle et un fond formé à partir du substrat; et une pluralité de micro-diodes électroluminescentes (micro-DEL) permettant d'émettre de la lumière, au moins l'une des micro-DEL étant à l'intérieur d'un évidement correspondant; la couche fonctionnelle étant conçue pour empêcher au moins une partie de la lumière émise par l'une des micro-DEL et incidente sur la paroi latérale de l'évidement correspondant d'être émise ultérieurement dans une région de sous-pixel adjacente.
