Plasma display panel
View Patent ↗In a PDP having row electrode pairs and column electrodes formed on the front glass substrate placed parallel to the back glass substrate with a discharge in between, each of the column electrodes faces a central area between adjacent transparent electrodes of the row electrode in the row direction, and is placed in a position closer to the transparent electrode serving as its partner for initiating an address discharge than to the unrelated transparent electrode located on the opposite side of the column electrode.
1. A plasma display panel including a pair of first and second substrates placed parallel to each other on either side of a discharge space, and including on the first substrate a plurality of row electrode pairs extending in a row direction and regularly arranged in a column direction and a plurality of column electrodes extending in the column direction and regularly arranged in the row direction, with a plurality of unit light emission areas being formed in matrix form within the discharge space for initiating a discharge therein by use of the row electrode pairs and the column electrodes,
wherein
row electrodes paired to constitute each of the row electrode pairs have discharge portions placed in accordance with the unit light emission areas and opposite to each other with a discharge gap in between, and
each of the column electrodes is placed parallel to a central area between the discharge portions of each row electrode which are adjacent to each other in the row direction, and in a position closer to the discharge portion serving as a partner of the column electrode for initiating a discharge than to another discharge portion which is located on the opposite side of the column electrode from the discharge portion serving as the partner for initiating the discharge.
2. A plasma display panel according to claim 1 , wherein
each of the row electrodes paired to constitute each row electrode pair has an electrode body extending in the row direction and a plurality of electrode projections regularly arranged along the electrode body and projecting toward the other row electrode of the row electrode pair so as to face the electrode projection of the other row electrode with the discharge gap in between, and
each of the electrode projections of the row electrode constitutes the discharge portion.
3. A plasma display panel according to claim 1 , wherein
each of the column electrodes has a column electrode body extending in the column direction and parallel to a central area between the discharge portions of each row electrode which are adjacent to each other in the row direction and are placed in accordance with the unit light emission areas, and column-electrode discharge portions extending out from the column electrode body in the row direction to face the discharge gap between the discharge portions, and
the column electrode body is placed in a position closer to the discharge portion serving as a partner for initiating a discharge than another discharge portion which is located on the opposite side from the discharge portion serving as the partner for initiating the discharge.
4. A plasma display panel according to claim 1 ,
comprising a partition wall unit provided between the pair of first and second substrates and having at least vertical walls each extending in the column direction to provide a partition between the unit light emission areas adjacent to each other in the row direction in the discharge space,
wherein each of the column electrodes is placed within a range in which the column electrode is opposite to the vertical wall in a thickness direction of the first and second substrates.
5. A plasma display panel according to claim 1 ,
comprising a partition wall unit provided between the pair of first and second substrates and having at least vertical walls each extending in the column direction to provide a partition between the unit light emission areas adjacent to each other in the row direction in the discharge space,
wherein each of the column electrodes is placed within a range in which the column electrode faces a central area between the vertical wall of the partition wall unit and the discharge portion of the row electrode in each unit light emission area.
