AC plasma display panel and driving method therefor
In a three-electrode AC plasma display panel, a plurality of X electrodes ( 22 ) and a plurality of Y electrodes ( 23 ) are alternately arranged parallel to each other on one of two, front and rear insulating substrates ( 20, 21 ) opposing each other, and a plurality of data electrodes ( 29 ) are arranged on the other insulating substrate to cross the X and Y electrodes ( 22, 23 ) at right angles. In this panel, cell separation partition walls ( 33 ) are arranged on the front insulating substrate, on which the X and Y electrodes ( 22, 23 ) are arranged, along the X and Y electrodes ( 22, 23 ). In a driving method for the three-electrode AC plasma display panel, progressive display is performed depending on whether discharge simultaneously occurs between all the adjacent pairs of X and Y electrodes ( 22, 23 ).
1 . A three electrode AC plasma display panel in which a plurality of X electrodes and a plurality of Y electrodes are alternately arranged parallel to each other on one of two, front and rear insulating substrates opposing each other, and a plurality of data electrodes are arranged on the other insulating substrate to cross the X and Y electrodes at right angles, comprising:
cell separation partition walls arranged on the front insulating substrate, on which the X and Y electrodes are arranged, along the X and Y electrodes; and
a discharge separation partition wall having a height smaller than a distance between the two opposing insulating substances and formed on the insulating substrate, on which the data electrodes are arranged, at a position to opposite a discharge gap formed between the adjacent pair of X and Y electrodes.
2 . A panel according to claim 1 ,
wherein a width of the data electrode at a position opposing the discharge gap is smaller than a width of the data electrode at positions opposing the X and Y electrodes.
3 . A panel according to claim 1 ,
wherein a width of the data electrode at a position opposing the center line of each of the X and Y electrodes in the longitudinal direction is smaller than a width of the data electrode at a position opposing other portions of the X and Y electrodes.
4 . A method for driving a panel according to claim 1 , comprising the steps of:
causing two vertically adjacent cells each involving either one of a pair of X and Y electrodes, to which an address pulse has been applied in synchronization with an application of a data pulse to the data electrode, to generate writing discharge simultaneously in the address period:
applying AC sustain pulses to the X and Y electrodes alternately in the sustain period, and
performing progressive display in dependence on the occurrence of discharge caused between respective pairs of X and Y electrodes in said adjacent cells.
