Abstract: The expression for “gamma” of tricolor picture tubes is derived and analyzed for its correlations with the various gun design parameters. The two methods of compensation for the different RBG-phosphor efficiencies (utilizing unequal drives and equal cutoff voltages for the triple gun or employing equal drives and unequal cutoff voltages) are discussed. The influence of manufacturing tolerances on gamma and the necessary gamma equalization are described. Gun designs are discussed which facilitate the utilization of equal drives on all three guns. The conclusion is derived that a gun triplet with different spacings in the triode may present a realistic solution.
