Abstract
(EN)
A device includes a display stack and an optical receiver. The display stack includes a set of opaque elements defining a translucent aperture. The translucent aperture extends through the display stack. The optical receiver is spaced apart from and behind a back surface of the display stack. At least one micro-optic element is formed on the back surface of the display stack, between the display stack and the optical receiver. The at least one micro-optic element includes a micro-optic element having a focal point located within the translucent aperture. The optical receiver is configured to receive light through the translucent aperture and the at least one micro-optic element.

Dispositif comprenant une dalle d'affichage et un récepteur optique. La dalle d'affichage comprend un ensemble d'éléments opaques définissant une ouverture translucide. L'ouverture translucide s'étend à travers la dalle d'affichage. Le récepteur optique est éloigné de la dalle d'affichage et est placé derrière une surface postérieure de cette dernière. Au moins un élément micro-optique est formé sur la surface postérieure de la dalle d'affichage, entre la dalle d'affichage et le récepteur optique. L'au moins un élément micro-optique comprend un élément micro-optique ayant un point focal situé à l'intérieur de l'ouverture translucide. Le récepteur optique est configuré pour recevoir de la lumière à travers l'ouverture translucide et l'au moins un élément micro-optique.
