Achieving proper color balance in field emis- sion displays is a challenge due to the unmatched efficiency of the phosphors. In general, blue phos- phors are much less efficient than red or green phos- phors thus they require more current to produce suf- ficient light. The following proposes a method of fabricating field emitters pixels that will compensate for the differences in efftciency by controlling the gate opening and thus the current emitted from a particular subpixel at a given gate voltage.
