Abstract:
A system and method are provided for repairing an emissive element display. If a defective emissive element is detected in a subpixel, a subpixel repair interface isolates the defective emissive element. The repair interface may be a parallel repair interface with n number of selectively fusible electrically conductive repair nodes, connected in parallel to a control line of the matrix. Alternatively, the repair interface may be a series repair interface with m number of repair nodes, selectively connectable to bypass adjacent (defective) series-connected emissive elements. If the subpixel emissive elements are connected in parallel, and a defective low impedance emissive element is detected, a parallel repair interface fuses open a connection between the defective emissive element and a matrix control line. If the subpixels include series-connected emissive elements, and a high impedance emissive element is detected, a series repair interface forms a connection bypassing the defective emissive element.
