Abstract:
Disclosed herein is a plasma display panel. The plasma display panel comprises partition walls between first and second substrates to separate discharge cells from each other. Each of the partition walls comprises a non-Pb based glass powder matrix, and a non-Pb based filler having a ratio of 5˜45 wt % with respect to the glass powder matrix.
Abstract:
A plasma display panel comprises: a plurality of substrate having a front substrate and a back substrate disposed opposite to each other; dielectric walls disposed between a front surface and a back surface, and defining discharge cells in cooperation with the front substrate and the back substrate; a plurality of discharge electrodes separately disposed around the discharge cells and buried into the dielectric walls; dummy electrodes formed at outer portions of the discharge electrodes disposed in one direction of the substrate and etched when over-etching takes place during the time of developing; and red, green and blue color fluorescent layers coated within the discharge cells.
Abstract:
A plasma display panel includes an upper plate having a sustain electrode, a lower plate having an address electrode, and a partition formed between the upper plate and the lower plate and having an inorganic ion exchanger. The yellow discoloration of the partition is prevented to improve color brightness and light permeability.
Abstract:
To reduce hydrocarbons existing inside the inner space of a PDP to thereby realize a PDP providing a high-quality picture and having a long life. A catalyst reacting with hydrocarbons is provided on protective layer (8) formed on front panel (1) and barrier ribs (12), phosphor layers (13), and base dielectric layer (11) formed on back panel (2), in an exposed manner to the inner space of the PDP, so that the hydrocarbons are oxidized or decomposed by the catalytic activity of the catalyst with the hydrocarbons.

Abstract:
The present invention provides a plasma display panel (PDP) with a structure that can reduce an outer reflection of an external light source and increase the reflection of visible rays emitted from the phosphor, remarkably increase the aperture ratio of the front panel, and remarkably reduce occurrence of a permanent residual image. The PDP includes: a transparent front panel; a rear panel disposed in parallel with the front panel; a plurality of opaque upper barrier ribs disposed between the front panel and the rear panel to define a plurality of discharge cells, and formed of a dielectric material; a lower discharge electrode and an upper discharge electrode disposed within the plurality of opaque upper barrier ribs so as to enclose the discharge cells; a plurality of lower barrier ribs disposed between the plurality of opaque upper barrier ribs and the rear panel; a phosphor layer disposed within a space defined by the plurality of lower barrier ribs; and a discharge gas disposed inside the discharge cells.
Abstract:
A spacer for keeping a space between two substrates formed from glass sheets, more particularly a space of small thickness, generally less than a few millimeters, over the entire area of the sheet substrates, in a device such as a display screen, vacuum-type insulating glazing or a flat lamp, the surface of said spacer being at least partly electronically conducting, characterized in that said spacer is formed from a core not exhibiting electronic conductivity, the shape and the constituent material of which are chosen to provide the thermomechanical integrity of the substrates in the final device, said core being at least partly coated with at least one layer of a glass exhibiting electronic conductivity, and capable of giving the spacer electronic conductivity at 50° C. of 10−13 to 10 ohm−1.cm−1.
Abstract:
A method of manufacturing a plasma display panel is disclosed. This method can collect impurity gas in the panel without an activation treatment at a high temperature. The method includes at least one of forming a dielectric layer on a principal face of a substrate, forming barrier ribs which partition a discharging space on the dielectric layer, and forming a phosphor layer between the barrier ribs. At least one of forming the dielectric layer, forming the barrier ribs, and forming the phosphor layer uses inorganic material into which solution including degassing material is impregnated.
Abstract:
A glass composition for a plasma display panel (PDP) and its fabrication method are disclosed. The composition, comprising a ZnO—B2O3 group and alkaline earth metal oxide, is environment-friendly, has a high discharge efficiency and is used as various PDP dielectric materials. The fabrication method allows to compose the low melting point unleaded non-alkali glass composition at a low cost.
Abstract:
In a plasma display panel having a front glass substrate on which row electrode pairs and column electrodes are provided, a second additional dielectric layer projects from a portion of the rear-facing face of a first additional dielectric layer opposite to a transverse wall member of the partition wall toward a back glass substrate, and extends in the row direction to provide a block between the discharge cells C adjoining to each other in the column direction on both sides of the transverse wall member. The column-electrode width of the second additional dielectric layer is smaller than that of the transverse wall member of the partition wall.
