Abstract:
A plasma display panel having a plurality of bi-discharge sources comprising a front substrate and a rear substrate coupled in parallel; a plurality of first electrodes, second electrodes and third electrodes in parallel disposed over the front substrate along a first direction; a plurality of rear substrate walls disposed in parallel over the rear substrate along a second direction orthogonal to the first direction. Each of the plurality of second electrodes is centered between each of the plurality of first and third electrodes, which leads to a bi-discharge source. In each of the plurality of second electrodes, one side is induced as having a plurality of positive charges and the other side with a plurality of negative charges, which are equal amount and thus result in charge counterbalance on the second electrode.
Abstract:
A front panel structure of Plasma Display Panel (PDP) is disclosed sequentially comprising a first electrode, a second electrode and a third electrode, wherein the second electrode has transparent electrodes located on both top and bottom sides of a bus electrode. A first discharge center is formed between a transparent electrode of the first electrode and one transparent electrode of the second electrode. A second discharge center is formed between the other transparent electrode of the second electrode and a transparent electrode of the third electrode. Therefore, an emitting cell of PDP has two discharge centers. To make the discharge more stable, we choose the first electrode and the third electrode to become the scan electrodes, or to form a thicker dielectric layer or discharge deactivation film below the second bus electrode as a scan electrode.
