US 11,908,846 B1 · Displays with non-periodic opaque structures

Abstract

A display may include light-emitting components such as light-emitting diodes on a transparent substrate. Conductive signal paths between the light-emitting components, driver integrated circuits for controlling the light-emitting components, and the light-emitting components themselves may be opaque. To mitigate diffraction artifacts caused by the opaque components, the opaque footprint of the display may be selected to include non-periodic portions. The non-periodic portions increase randomness and reduce periodicity within the opaque footprint, which mitigates perceptible diffraction artifacts when viewing the display. One or both of the component mounting portions and interconnect portions of the opaque footprint may be non-periodic. The component mounting portions may have random shapes. The interconnect portions may follow random paths between the component mounting portions.

Dependent claims

A display comprising:

a transparent substrate;
a plurality of light-emitting components mounted on the transparent substrate, wherein the plurality of light-emitting components comprises a plurality of bottom-emitting light-emitting diodes that are configured to emit light through the transparent substrate;
at least one opaque layer that defines an opaque footprint on the transparent substrate, wherein the opaque footprint comprises non-periodic portions that mitigate diffraction artifacts;
and
a dielectric layer interposed between at least one bottom-emitting light-emitting diode of the plurality of bottom-emitting light-emitting diodes and the transparent substrate, wherein the at least one opaque layer comprises a metal layer that is interposed between the dielectric layer and the transparent substrate.
