  • 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.

  • Patent number: 11908884
    Abstract: An inductive device includes an insulating layer, a lower magnetic layer, and an upper magnetic layer that are formed such that the insulating layer does not separate the lower magnetic layer and the upper magnetic layer at the outer edges or wings of the inductive device. The lower magnetic layer and the upper magnetic layer form a continuous magnetic layer around the insulating layer and the conductors of the inductive device. Magnetic leakage paths are provided by forming openings through the upper magnetic layer. The openings may be formed through the upper magnetic layer by semiconductor processes that have relatively higher precision and accuracy compared to semiconductor processes for forming the insulating layer such as spin coating. This reduces magnetic leakage path variation within the inductive device and from inductive device to inductive device.
