Abstract
The present invention teaches a field emission display ("FED") architecture for isolating display grids, wherein an FED has a plurality of pixels. Each of the pixels comprise at least two field emitter tips for displaying information to the pixel and a pixelator for driving the field emitter tips. Further, an isolated display grid is incorporated for each of the field emitter tips. Each display grids is coupled to a bus having a predetermined voltage by a link. In one embodiment of the present invention, the link can be disintegrated by internal or external means. In a second embodiment, the FED comprises a first and second bus, each of bus having a predetermined voltage, whereby a first isolated display grid is coupled to the first bus by a first link and a second isolated display grids is coupled to the second bus by a second link.
