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.
