Mosaic field emission display with internal auxiliary pads
 The design of a large area display made up of a plurality of field emission display modules is described. The modules have been modified in several ways relative to prior art designs. The cathode and gate lines near the module's edge have been substantially shortened. This feature, in combination with the use of a rabbet joint for attaching thinner than usual edge plates, allows the modules to be butted up against each other such that pixels in adjoining modules are no further apart than pixels in the same module. Because of the thinner edge plates and the general compatibilty of the process, the use of internal supports between the front and rear plates becomes mandatory. Vacuum piping for the modules is located near an edge in dark space or under a green pixel, with the gettering layer being formed inside the piping. The modules all plug into a printed circuit board which includes a custom chip for driving the display.
