Abstract: An electronic display may include a pixel circuit. The pixel circuit may include memory storage to store data values representative of image data to be depicted via the pixel circuit. The memory storage may also include memory components for storing bits of the data value. The pixel circuit may also include a light-emitting device for emitting light based at least in part on the data value and a controller. The controller may receive the data value and store the bits based on a mapping between the bits and the memory components. The mapping may be determined based on routing one or more of the bits associated with one or more defective memory components of the memory components to one or more other memory components of the memory components. The controller may also drive the light-emitting device to emit light based on the bits stored in accordance with the mapping.

Abstract: Systems and methods may reduce or eliminate image artifacts due to a defective pixel of an electronic display. An electronic display may include pixels that respectively include a self-emissive element, pixel drive circuitry that supplies a pixel drive current to drive the self-emissive element, and signal routing circuitry that reduces or eliminates a visual artifact due to a defective pixel among the pixels. The signal routing circuitry may do this by turning off the self-emissive element, supplying image data from the pixel drive circuitry to a first adjacent pixel, or receiving image data from other pixel drive circuitry from the first adjacent pixel or a second adjacent pixel.

Abstract: A system may include a display driven using display driving circuitry to present an image via pixels. The display driving circuitry may include a sensor core compatible with one or more strain sensing circuits. The same sensor core may be used by a control system of the display to sense a stress applied to a strained region of a display using a current divider sensing circuit and/or a Wheatstone bridge sensing circuit.

Abstract: The present disclosure relates to systems and methods for operating a control signal to communicate signals using a first antenna and a first frequency band in response to determining that intra-device operations are occurring or are expected to occur, that a first amount of energy received by the first antenna is less than a threshold amount of energy, and that the first antenna is unaffected by the intra-device operations. The control signal may also delay communication of the signals in response to determining that intra-device operations are occurring, and that first amount of energy is greater than or equal to the threshold amount of energy.
