Auxiliary Address Pulse Driving Scheme for Improving Luminance and Luminous Efficiency in 42-inch WVGA Plasma Display Panel

The effects of an auxiliary address pulse driving scheme, in which an auxiliary short pulse is applied to the address electrode during a sustain-period, were examined under the various image patterns of the 42-inch WVGA ac-PDP. When the auxiliary address pulse driving scheme was applied, the luminance of the red, green and blue cells were measured respectively. And the luminance, luminous efficiency, and current were measured under the full-white pattern of the 42-inch ac-PDP. As a result, the luminance of blue cells was improved approximately by 17 %, whereas the luminous efficiency of the full-white pattern was improved approximately by 34 % without a misfiring discharge in comparison with conventional driving scheme.
