Abstract

Methods and apparatus for repairing inoperative pixels in a display (10) are provided. In particular, the present invention provides methods and apparatus for improving the effective yield rates of displays, such as liquid crystal micro-displays, by disconnecting inoperative pixels (30) from their defective drive circuitry (32) and tying such pixels to the working drive circuit (42) of a nearby pixel. A display can be repaired without the need to provide redundant drive circuitry underneath each pixel (30, 40).
