Improvement of luminance and luminous efficiency using address voltage pulse during sustain-period of AC-PDP

To improve the luminance and luminous efficiency of a surface-discharge alt ernate current plasma display panel (ac PDP), auxiliary voltage pulses were applied to the address electrode during a sustain-period. The luminance an d luminous efficiency exhibited maximum values at an address voltage of 100 V and pulse width of 1 mus. An improved luminance of 21.4% and luminous ef ficiency of 24% were simultaneously obtained based on the proper adjustment of the widths and amplitudes of the address voltage pulses. Accordingly, t he proper control of the amplitudes and pulse widths of the auxiliary addre ss voltage during a sustain-period can improve both the luminance and the l uminous efficiency in a surface-discharge ac PDP.
