  • Patent number: 7508139
    Abstract: A novel design for a plasma display panel where a dielectric grid structure is formed between the front and the rear substrate. Some or all of the electrodes are formed within the dielectric grid structure. The electrodes surround individual discharge cells and thus produce a more efficient discharge. A resistive element is built into the electrodes to reduce current and to reduce power consumption. The sustain discharge electrodes, made of X and Y electrodes each are made of at least two separate electrode lines, all four electrodes being formed within the dielectric grid. By such a design, power consumption is reduced and light emission efficiency is improved.
