A plasma display panel (PDP) which can reduce the cost and time of manufacturing a plasma display device, and which can improve heat transfer efficiency of a plasma display device, comprises: a transparent front substrate; a rear substrate disposed parallel to the front substrate; an electromagnetic wave shielding layer fixed on the front substrate; a plurality of discharge cells defined by barrier ribs disposed between the front substrate and the rear substrate; a plurality of address electrodes extending over the discharge cells and disposed in a given direction; a rear dielectric layer covering the address electrodes; a plurality of fluorescent layers disposed in the discharge cells; a plurality of sustaining electrode pairs extending in a direction which crosses the given direction of the address electrodes; a front dielectric layer covering the sustaining electrode pairs; and a discharge gas filling the discharge cells.
Abstract:
The plasma display apparatus has a noise filter circuit with a noise filter connected to an AC supply disposed at the back side of a plasma display panel. The plasma display apparatus also has a back cover composed of a magnetic metal material disposed at the back side of the plasma display panel to cover the noise filter circuit, wherein magnetic lines of force in a core, made of magnetic material and including the noise filter direct approximately identical to the in-plane direction of the back cover. The configuration can eliminate audible noises because the amount of leakage flux passing through the back cover is reduced.
Abstract:
A structure and driving method of a plasma display panel is provided, in which an amount of priming particles within a discharge cell increases to reduce discharge lag of address discharge. The structure of the plasma display panel includes a plurality of sustain electrode pairs successively formed on an upper electrode, a plurality of common electrodes formed one by one between a pair of the sustain electrodes, and a dielectric layer formed on the substrate to deposit the sustain electrodes and the common electrodes. The method for driving the plasma display panel includes the steps of applying a common pulse, which is periodically turned on/off, to the common electrodes, applying a scan pulse to one of a pair of the sustain electrodes, and applying an address pulse to the address electrodes when the scan pulse is applied to the one sustain electrode. Thus, since discharge conditions within the discharge cell can be improved, discharge lag less occurs than the related art plasma display panel.
Abstract:
A plasma display device disclosed herein is capable of enhancing the contrast of external light, facilitating application of phosphor paste on the bottom of each space surrounded by lattice-like barrier ribs, and reducing a variation in the amount of the phosphor paste applied as much as possible. The lattice-like barrier ribs include lateral ribs extending along a first direction while being nearly in parallel to each other, and vertical ribs extending along a second direction different from the first direction while being nearly in parallel to each other. Each of the lateral ribs is composed of two or more rows of rib elements. Notches for communicating spaces surrounded by the vertical ribs and the lateral ribs to each other in the first direction and/or the second direction are formed at least in portions of the vertical ribs and/or the lateral ribs.
Abstract:
A plasma display panel is provided, including lower and upper substrates separated from each other to form a discharge space therebetween. A plurality of partitions are provided between the lower and upper substrates to partition the discharge space to define the discharge cells, and a plurality of first and second discharge electrodes generate a discharge within the discharge cells. A plurality of fluorescent layers are provided to inner surfaces of the discharge cells, each of the fluorescent layers being exited by the discharge to generate visible rays of light, and a plurality of light shielding elements are provided to the upper substrate to prevent external rays of light from entering the discharge cells, wherein a plurality of light focusing elements provided to the upper substrate focus the visible rays of light generated in the discharge cells and emit the visible light.
Abstract:
An apparatus for burning green sheets of a plasma display panel comprises a feeding part that feeds a green sheet to a plasma display panel substrate, a heat and pressure roller that heats and compresses the green sheet and the plasma display panel substrate from above the plasma display panel substrate, and a heating module that applies heat to a contact portion between the green sheet and the plasma display panel substrate. The heat and pressure roller applies heat and pressure to the green sheet to bring the green sheet into intimate contact with the plasma display panel substrate and to remove residual solvent from the green sheet.
Abstract:
A plasma display panel can stabilize address properties. A front substrate (1) and a back substrate (2) are disposed to face each other, and a discharge space (3) is formed and partitioned by barrier ribs (11) so as to form priming discharge cells (16) and main discharge cells (12). Forming priming electrodes (15) onto a dielectric layer (17) in the priming discharge cells (16) can secure the isolation voltage between data electrodes (10) and the priming electrodes (15), and can also secure the generation of a priming discharge prior to a main discharge.
Abstract:
The present invention relates to a plasma display panel, and more particularly, to a cell structure of a plasma display panel. In a plasma display panel in which square cells constitute a delta type barrier rib structure, a red cell and a green cell are alternately formed in a first horizontal cell line of the cells, a blue cell is located at the lower center between the red cell and the green cell in a second horizontal cell line of the cells, the blue cell is alternately formed together with a blank cell, and the first horizontal cell line and the second horizontal cell line are alternately formed in the vertical direction. Accordingly, brightness, efficiency and the contrast ratio are improved and high-speed driving is accomplished.
Abstract:
A panel assembly for a PDP having ribs of partitioning a discharge space on a substrate includes grooves each formed between adjacent ribs. Each of the grooves has deeper groove regions to be luminous areas and shallower groove regions to be non-luminous areas. Black material layers are formed on the shallower groove regions.
Abstract:
A discharge inert film (22) is made of an aggregate of fine particles not substantially containing any inorganic binder. Each of sustain discharge electrodes (XB, YB) includes a plurality of discharge gap adjoining portions (a), a bus portion (b) and a plurality of bridge-building portions (c). The bus portion (b) adjoins the electrode pair gap portion (NG), extending along a second direction (D2). Each of bridge-building portions (c) extends towards a discharge gap portion (DG). The bridge-building portions (c) are connected to the discharge gap adjoining portions (a), respectively, and these adjoining portions (a) adjoin the discharge gap portion (DG) and are arranged therealong. The film (22) is so disposed as not to cover the discharge gap adjoining portions (a). When a surface discharge is generated between the sustain discharge electrodes (X, Y) during a reset period, the potential difference between the electrodes (X, Y) is gradually increased.
