Title (EN) MICRO ASSEMBLED HYBRID DISPLAYS AND LIGHTING ELEMENTS
(FR) MICROAFFICHEURS HYBRIDES ASSEMBLÉS ET ÉLÉMENTS D'ÉCLAIRAGE
Abstract:
(EN) The disclosed technology relates generally hybrid displays with pixels that include both inorganic light emitting diodes (ILEDs) and organic light emitting diodes (OLEDs). The disclosed technology provides a hybrid display that uses a mixture of ILEDs and OLEDs in each pixel. In certain embodiments, each pixel in the hybrid display includes a red ILED, a blue ILED, and a green OLED. In this instance, the OLED process would not require a high resolution shadow mask, thereby enhancing the manufacturability of OLEDs for larger format displays. Additionally, the OLED process in this example would not require any fine lithography. The OLED subpixel (e.g., green subpixel) can be larger and the ILEDs can be small (e.g., micro-red and micro-blue ILEDs). The use of small ILEDs allows for other functions to be added to the pixel, such as micro sensors and micro integrated circuits.
(FR) La présente invention concerne, d'une manière générale, des afficheurs hybrides avec des pixels qui comportent à la fois des diodes électroluminescentes inorganiques (ILED) et des diodes électroluminescentes organiques (OLED). La technique selon l'invention permet d'obtenir un afficheur hybride qui utilise un mélange d'ILED et d'OLED dans chaque pixel. Dans certains modes de réalisation, chaque pixel de l'afficheur hybride comporte une ILED rouge, une ILED bleue et une OLED verte. Dans ce cas, un traitement OLED ne nécessiterait aucun masque perforé à haute résolution, ce qui permettrait d'améliorer l'aptitude à la fabrication d'OLED pour des afficheurs de plus grand format. En outre, le traitement OLED de cet exemple ne nécessiterait aucune lithographie fine. Le sous-pixel OLED (par exemple, un sous-pixel vert) peut être plus grand et les ILED peuvent être petites (par exemple, des micro-ILED rouges et bleues). L'utilisation de petites ILED permet d'ajouter d'autres fonctions au pixel, telles que des microcapteurs et des microcircuits intégrés.
