Title (EN) COLLECTION AND GUIDING OF AMBIENT LIGHT TOWARDS DISPLAY LAYER
(FR) COLLECTE ET GUIDAGE DE LUMIÈRE AMBIANTE VERS UNE COUCHE D'AFFICHAGE
Abstract:
(EN) An apparatus include a housing having a top opening, and a sidewall and a bottom surface defining a cavity. The apparatus includes a display assembly. The display assembly includes an electronic transmissive display layer within the cavity to display an image viewable from the top opening of the housing. The display assembly includes a light collector within the cavity and having an optical opening at the top opening of the housing to collect ambient light. The display assembly includes a light guide layer within the cavity to guide the collected ambient light towards and through the display layer. The apparatus includes a processing device within the cavity to generate data to display using the display layer.
(FR) Un appareil comprend un boîtier ayant une ouverture supérieure, et une paroi latérale et une surface inférieure définissant une cavité. L'appareil comprend un ensemble d'affichage. L'ensemble d'affichage comprend une couche d'affichage transmissif électronique à l'intérieur de la cavité pour afficher une image visible depuis l'ouverture supérieure du boîtier. L'ensemble d'affichage comprend un collecteur de lumière à l'intérieur de la cavité et ayant une ouverture optique au niveau de l'ouverture supérieure du boîtier pour collecter la lumière ambiante. L'ensemble d'affichage comprend une couche de guidage de lumière à l'intérieur de la cavité pour guider la lumière ambiante collectée vers et à travers la couche d'affichage. L'appareil comprend un dispositif de traitement à l'intérieur de la cavité pour générer des données à afficher à l'aide de la couche d'affichage.
