Abstract:
A method of formimg barrier ribs for a plasma display panel including the steps of: roughening a barrier rib formation surface of a substrate; forming a barrier rib material layer on the roughened barrier rib formation surface; and forming, on the barrier rib material layer, a mask having a pattern corresponding to the barrier ribs to be formed. In addition, forming the ribs includes partially removing the barrier rib material layer by blasting an abrasive against the barrier rib material layer to form the barrier ribs below the mask. Removing the mask reveals barrier ribs for partitioning a discharge space formed on the substrate.
Abstract:
There are provided a coating composition that can satisfactorily form a film even at a low temperature by chemical means in a simple and stable manner, has excellent film strength, adhesion, protective effect and other properties in the form of a functional film and can form a functional film at a low cost, a process for producing the coating composition, a functional film, and a process for producing the functional films.A hydrolyzable reaction site is partially hydrolyzed to prepare a sol of a partial hydrolyzate which is then coated on a substrate. The coating is then baked to prepare a corresponding metal oxide film, thereby forming a thin protective layer. Since no hydrolyzate is precipitated in the sol of the partial hydrolyzate, excellent film strength, adhesion, protective effect and other properties are offered. The metallic compound having a hydrolyzable reaction site is selected from an organometal compound, such as a metal alkoxide, an organometal complex, and an organometal acid salt, and an inorganic metal compound, such as an inorganic metal salt. The functional film of the present invention can be utilized in a protective layer formed of, for example, magnesium oxide in a plasma display.
Abstract:
A method and apparatus (50, 70, 90) for making a back glass substrate (24) for a plasma display panel (20) by forming hot sheet glass G heated above its annealing point and embodied either as a continuous ribbon (60) or discrete sheets (74). The hot forming provides the hot sheet glass G with gas discharge troughs (38) spaced by barrier ribs (40). The hot forming of the sheet glass G heated above its annealing point can be performed by a rotatable forming member (62) having curved projections (66) or by a press member (78) having elongated projections (84). The constructed plasma display panel (20) has a front glass substrate (22) and a back glass substrate (24) with the gas discharge trough and barrier rib construction made by hot forming above the annealing point. The gas discharge troughs (38) can be hot formed with bottom surfaces (95) that have an undulating shape along their lengths to enhance luminescence of phosphors (48), and the barrier ribs (40) can have distal ends with openings (98) that provide communication between the gas discharge troughs (38) and that are located adjacent peaks (100) of the trough bottom surfaces (94) remote from the location of discharge.
Abstract:
A plasma display panel includes a plurality of discharge cells formed with a plurality of partition walls arranged at fixed intervals between a front substrate and a rear substrate disposed in parallel spaced at a certain distance. A fluorescent material film is formed on a portion of an inside surface of each of the discharge cells. A discharge gas is sealed in each of the discharge cells and is converted into a plasma upon the occurrence of a discharge in each of the discharge cells. Each of the partition walls is formed with a stack of at least more than one permanent magnets magnetized with N and S poles for forming a magnetic field in the discharge cell. The electrons existing in the plasma are thus accelerated toward the fluorescent material film upon occurrence of a discharge in the discharge cell by the magnetic field such that the fluorescent material film can be excited, whereby a luminance of a panel screen can be improved, equal sized magnetic partition walls can be formed, and production time of the magnetic partition walls can be shortened.

In the surface discharge plasma display apparatus according to the present invention, the emitting efficiency is improved to increase the level thereof, the amount of the current which passes through each of the electrodes may be decreased, thereby the consumption power per emitting pixel region being decreased. Thus, the amount of the heat generated in a unit area of the plasma display apparatus may be decreased, so that the address failure of the emitting pixel region due to the generated heat may be prevented.
