The positive column discharge characteristics in the long gap 440 μm are investigated based on the voltage distribution among three electrodes. In particular, the effects of the amplitude and width of the short pulse applied to the address electrode on the positive column discharge characteristics are examined intensively. By proper controlling of the amplitude and width of the address short pulse, it is found that the positive column discharge in the long gap is well constructed. As a result, under the stable static voltage margin condition, the firing and sustaining voltages are as low as those of conventional short gap60 μm discharge and the color purity is improved. Moreover, the luminous efficiency increases up to 60% in comparison with the conventional case.
