    Abstract: An electronic device may display image content via an electronic display by controlling light emission from display pixels of the electronic display. A processor of the electronic device may receive image data destined for a defective display pixel (e.g., dim pixel, dead pixel). The processor may convert a gray level of the image data into a luminance domain to generate a target luminance that would have been emitted by the defective display pixel had the display pixel not been defective. After selecting a compensation mask, the processor may distribute the target luminance of the defective display pixels to nearby non-defective pixels of the electronic display to conceal the presence of the defective display pixel.

    Abstract: An apparatus includes a non-volatile storage circuit that includes a primary copy of a data value in a first storage location and a redundant copy of the data value in a second, different storage location. The data value includes one or more bits. The apparatus further includes an error detection circuit configured to retrieve contents of the first and second storage locations in response to a request for the data value. The error detection circuit is further configured to perform an error correction operation on the retrieved contents of the first and second storage locations to generate a data output responsive to the request, and to perform an error detection operation to generate an error signal that indicates whether the retrieved contents of the first and second storage locations are different.

    Abstract: An electronic device may include a display. The display may be formed by an array of light-emitting diodes mounted to the surface of a substrate. The substrate may be a silicon substrate. Circuitry may be located in spaces between the light-emitting diodes. Circuitry may also be located on the rear surface of the silicon substrate and may be coupled to the array of light-emitting diodes using through-silicon vias. The circuitry may include integrated circuits and other components that are attached to the substrate and may include transistors and other circuitry formed within the silicon substrate. Touch sensor electrodes, light sensors, and other components may be located in the spaces between the light-emitting diodes. The substrate may be formed from a transparent material that allows image light to reach a lens and image sensor mounted below the substrate.
