Abstract
A system and method for repairing an OLED display having an array of OLED pixels including at least one inoperative OLED pixel, wherein each OLED pixel is controlled by a pixel driver circuit having a fusible element. The system includes a first switch for reducing an energizing signal to the OLED pixel array, the energizing signal exceeding a threshold level below which the OLED pixels should not emit light. A second switch is provided for increasing a bias signal to the OLED pixel array, the bias signal exceeding a threshold level above which the fusible element of the inoperative OLED pixels are blown, such that inoperative OLED pixels no longer emit light.
