20080218439 | PLASMA DISPLAY PANEL AND IMAGING DEVICE USING THE SAME - A plasma display panel and an imaging device realize a high luminous efficiency, a long lifetime and stable driving. The plasma display panel uses a discharge-gas mixture containing at least Xe, Ne and He. A Xe proportion of the discharge-gas mixture is in a range of from 2% to 20%, a He proportion of the discharge-gas mixture is in a range of from 15% to 50%, the He proportion is greater than the Xe proportion, and a total pressure of the discharge-gas mixture is in a range of from 400 Torr to 550 Torr. A width of a voltage pulse to be applied to an electrode serving as an address electrode is 2 μs or less. | 09-11-2008 |
20090021167 | PLASMA DISPLAY PANEL AND MANUFACTURING METHOD THEREOF - A technology capable of preventing or suppressing a display defect in a PDP (detrimental effect due to local contamination of the display area caused by admixture of impurity gas at the time of introducing discharge gas) is provided. In a PDP, first barrier ribs and first phosphors formed between the first barrier ribs are provided so as to correspond to a display area. In a non-display area outside the display area, an air hole for evacuation from a discharge space and gas filling into the discharge space is provided in a part of an outer perimeter of the panel. Further, an area in which second phosphors having a property of absorbing impurity gas are formed is formed at a position between the display area and the air hole in a part of the non-display area, in particular, in a part of a dummy rib area. | 01-22-2009 |
20090121631 | Plasma display panel and production method therefor - A plasma display panel production method is provided for producing a plasma display panel including a first substrate, a second substrate opposed to the first substrate, a barrier rib partitioning a space defined between the first and second substrates into a plurality of discharge spaces, and a seal frit portion provided between peripheral inner surface portions of the first and second substrates to seal the first and second substrates. The method comprises the steps of: forming a seal frit portion on one of the first and second substrates, and forming a barrier rib on the second substrate; combining the first substrate and the second substrate with a spacer of the same material as the seal frit portion being provided between the first substrate and a top of the barrier rib; pressing peripheral portions of the first and the second substrates from outside by a pressing member; heating the first and second substrates to a temperature not lower than a softening temperature of the seal frit portion while evacuating the space defined between the first and second substrates; and introducing a discharge gas into the space defined between the first and second substrates after the evacuating step. | 05-14-2009 |
20090160336 | PLASMA DISPLAY PANEL - A high-definition, high-reliability plasma display panel having a simple structure and having a stably ensured gas-exhaust passage. In the plasma display panel, display electrodes and address electrodes crossing these display electrodes are provided between a pair of substrate defining an electric discharge space, display lines produced by surface discharge are provided between adjacent display electrodes, discharge luminous regions are provided at cross sections between display lines and address electrodes, partitions ( | 06-25-2009 |
20090162615 | METHOD FOR MANUFACTURING PLASMA DISPLAY PANEL AND PLASMA DISPLAY PANEL - A plasma display panel (PDP) having a front substrate structure (first substrate structure) and a back substrate structure (second substrate structure) arranged so as to be opposed to each other via a discharge space is manufactured in the following manner. A sealing member arranged in a frame shape so as to surround outside of a barrier rib formation region where barrier ribs partitioning a discharge space are arranged and a plurality of supporting members arranged in a region between an outer periphery of the barrier rib formation region and the sealing member are formed, respectively. The supporting members are made from material having a softening point higher than that of material for the sealing member, the height of the supporting members is made higher than that of the barrier ribs, and the height of the sealing member is made higher than the height of the supporting members. | 06-25-2009 |
20090174329 | PLASMA DISPLAY PANEL - A plasma display panel, in which discharge gas is filled in a space between a pair of substrates facing each other, has a plurality of display electrodes which extend in the horizontal direction and address electrodes which extend in the vertical direction and cross with the display electrodes, formed to the pair of substrates; and lattice-shaped ribs having vertical ribs and horizontal ribs that demarcate unit emission areas and formed on one of the substrates, wherein the rib has a pattern which partially becomes narrower from a first width to a second width, and returns to a first width in plan view so that the height of the second width portion is lower than the height of the first width portion. Thereby a plasma display panel having a rib structure with improved exhaust conductance can be provided. | 07-09-2009 |
20090302763 | PLASMA DISPLAY PANEL AND METHOD FOR MANUFACTURING THE SAME - In a plasma display panel wherein lattice-like ribs are formed, an impurity gas inside the panel is easily exhausted. The panel has a paired substrates facing each other. The peripheral portions of the panel are bonded to each other to be sealed. The panel is manufactured by allowing an impurity gas located between the substrates to be exhausted upon carrying out the sealing/bonding process. The panel includes a cell-defining rib and a dummy rib. The cell-defining rib has longitudinal ribs and lateral ribs, which is formed in a display area between the paired substrates. The dummy rib has the same shape as that of the cell-defining rib, which is formed in a non-display area which covers from an outer edge of the display area over to the periphery of the substrates, a ventilation passage being formed in the non-display area in which the dummy rib is formed. | 12-10-2009 |
