Through-display optical transmission, reception, or sensing through micro-optic elements

Abstract:

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.
