Abstract
Devices and methods of their fabrication for pixels or displays are disclosed. Pixels and displays having redundant subpixels are described. Subpixels are initially isolated by an unprogrammed antifuse. A subpixel is connected to the display by programming the antifuse, electrically connecting it to the pixel or display. Defective subpixels can be determined by photoluminescent testing or electroluminescent testing, or both. A redundant subpixel can replace a defective subpixel before pixel or display fabrication is complete.
