Abstract:
1. Apparatus for use with a liquid crystal micro-display built on a silicon integrated circuit substrate, the substrate having an integral complimentary metal-oxide semiconductor (CMOS) control chip containing CMOS drive circuitry, the drive circuitry comprising a plurality of pixel drive circuits, each pixel drive circuit electrically connected to a corresponding pixel, the apparatus comprising: means for identifying a defective pixel drive circuit electrically connected to an inoperative pixel; means for disconnecting the electrical connection between the defective pixel drive circuit and the inoperative pixel; and means for electrically connecting the inoperative pixel to a working pixel drive circuit coupled to a nearby pixel by means of a bypass bit latch, such that the defective pixel drive circuit is bypassed and the inoperative pixel is driven from the working pixel drive circuit of the nearby pixel, the nearby pixel comprising one of an adjacent pixel or a non-adjacent pixel.
