Filed: 1999-07-26
Abstract: PURPOSE: A PDP(plasma display panel) is provided to enhance white color purity by increasing brightness and efficiency in light emission higher than a former PDP and keeping a brightness ratio between discharge cells regular. CONSTITUTION: An area between sustain electrodes starts to be discharged by potential difference between first/second sustain electrodes(132,132',131,131'). An electric field causing discharging reaches plural pads(141-143) on the edge of discharge cells when the discharging is diffused to the entire discharge area. A discharge current flows fast and the pads limit discharging. The blue third pad(143) having the smallest width is limited in discharging slightly less than the other pads. Thus, the blue fluorescent discharge cell has a higher brightness than the others. The red second pad having the largest width is limited in discharging more than the third pad so that the red discharge cell has a lower brightness than the others do. Therefore, white color purity is increased on discharging all of the discharge cells under the same conditions.
