Title
(EN) VARIABLE-PITCH COLOR EMITTING DISPLAY
(FR) DISPOSITIF D'AFFICHAGE À ÉMISSION DE COULEURS À PAS VARIABLE
Abstract
(EN)
This disclosure relates to the use of variable-pitch light-emitting devices for display applications, including for displays in augmented reality, virtual reality, and mixed reality environments. In particular, it relates to small (e.g., micron-size) light emitting devices (e.g., micro-LEDs) of variable pitch to provide the advantages, e.g., of compactness, manufacturability, color rendition, as well as computational and power savings. Systems and methods for emitting multiple lights by multiple panels where a pitch of one panel is different than pitch(es) of other panels are disclosed. Each panel may comprise a respective array of light emitters. The multiple lights may be combined by a combiner.
(FR)
La présente invention concerne l'utilisation de dispositifs électroluminescents à pas variable pour des applications d'affichage, y compris pour des dispositifs d'affichage en réalité augmentée, en réalité virtuelle et en environnements de réalité mixte. En particulier, l'invention concerne des dispositifs électroluminescents (des micro-DEL, par exemple) de petite taille (de taille micrométrique, par exemple) ayant un pas variable pour fournir les avantages de la compacité, de la fabricabilité, du rendu de couleur, ainsi que des économies de calcul et d'énergie, par exemple. L'invention concerne des systèmes et des procédés servant à émettre de multiples lumières par de multiples panneaux, un pas d'un panneau étant différent du ou des pas d'autres panneaux. Chaque panneau peut comprendre un réseau respectif d'émetteurs de lumière. Les lumières multiples peuvent être combinées par un combinateur.
