Abstract: A design for a field emission device comprising a cold cathode emitter, a control gate and a focus gate, is discussed. The focus gate is connected to the emitter voltage source and a ballast resistor is inserted between this connection point and the emitter. This ensures that the focus gate will always be more negative than the emitter, this difference in potential increasing with increasing emitter current. This leads to a linear current-voltage characteristic for the device and also makes for a tighter electron beam than that provided by designs of the prior art, A physical realization of the design is described along with a cost effective method for manufacturing said physical realization.

Abstract: 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.
