Title (EN) MICRO- AND NANO-STRUCTURED LED AND OLED DEVICES
(FR) DISPOSITIFS DE LED ET OLED À STRUCTURE MICROMÉTRIQUE ET NANOMÉTRIQUE
Abstract: front page image
(EN)Structured LED devices and component structures with improved efficiency and reduced defects are enabled by the use of micro- or nano-structured features that reduce lattice strain and improve p-doping in inorganic LEDs, and facilitate carrier injection and recombination of OLEDs. The nanostructures can also confine current flow and provide internal light guiding to enhance efficiency and thereby improve device performance.
(FR)La présente invention concerne des dispositifs LED structurés et des structures de composants présentant une efficacité améliorée et des défauts moins nombreux, qui sont activés par l’utilisation de caractéristiques à structure micrométrique ou nanométrique qui réduisent la contrainte de réseau et améliorent le dopage p dans des LED inorganiques, et qui facilitent l’injection de charge et la recombinaison de plusieurs OLED. Les nanostructures peuvent également confiner le flux de courant et permettre un guidage de lumière interne pour améliorer l’efficacité et de ce fait améliorer la performance des dispositifs.
