  • Patent number: 11908846
    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.
