20080238318PHOTOSENSITIVE PASTE COMPOSITION, BARRIER RIB PREPARED USING THE COMPOSITION AND PLASMA DISPLAY PANEL COMPRISING THE BARRIER RIB - Photosensitive paste compositions, barrier ribs of plasma display panels (PDPs) prepared using the same, and PDPs including the barrier ribs are provided. The photosensitive paste composition includes an organic-inorganic complex sol and an inorganic material, wherein the average refractive index (N10-02-2008
20090058297PROTECTING LAYER COMPRISING MAGNESIUM OXIDE LAYER AND ELECTRON EMISSION PROMOTING MATERIAL, METHOD FOR PREPARING THE SAME AND PLASMA DISPLAY PANEL COMPRISING THE SAME - A protecting layer is formed of a magnesium oxide layer and electron emission promoting material formed on the magnesium oxide layer. The electron emission promoting material may be patterned on the magnesium oxide layer, or may be sprayed and heat-treated on the surface of the magnesium oxide layer. The protecting layer exhibits excellent electron emission characteristics while not being substantially damaged by plasma ions, thereby improving the reliability of a PDP.03-05-2009
20090186187PHOTOSENSITIVE PASTE COMPOSITION, BARRIER RIBS PREPARED USING THE COMPOSITION AND PLASMA DISPLAY PANEL COMPRISING THE BARRIER RIBS - A photosensitive paste composition includes: a fluoride sol dispersed in an organic material; and an inorganic material, wherein an average refractive index of the fluoride sol N07-23-2009
20100060139MATERIAL FOR FORMING PROTECTIVE LAYER, METHOD OF PREPARING THE MATERIAL, AND PDP COMPRISING THE PROTECTIVE LAYER - Disclosed is a material for forming a protective layer, a protective layer employing the material and a PDP with the protective layer. Unlike conventional protective layers which employ MgO created in conditions of pressurized artificial gas, the instant protective layer uses MgO created by heating Mg and allowing it to oxidize naturally in air. The result is MgO with fewer defects that is more effective as a protective layer in many uses, such as in a PDP. The instant MgO also shows many specific spectral characteristics and contains impurities in amounts of less than about 2 ppm each. Also disclosed is a PDP which takes advantage of the advantages of the inventive protective layer.03-11-2010
20100164361PLASMA DISPLAY PANEL PROTECTIVE LAYER - A plasma display panel (PDP) protective layer including a ternary compound in the form of BaXO, wherein X is selected from the group consisting of Sc, Y, Gd, La, Er, Ho, Nd, Sm, and Ce. Such protective layer has excellent electron emission characteristics and phase stability.07-01-2010
20100308710MATERIAL FOR PREPARING PROTECTIVE LAYER AND PLASMA DISPLAY PANEL COMPRISING THE PROTECTIVE LAYER - A plasma display panel (PDP) including a protective layer and a material for preparing the protective layer that can be easily fabricated and has little defects, includes a magnesium oxide (MgO) powder including a cathode rays emission spectrum having a first emission peak in a wavelength in the range of 300 to 450 nm, a second emission peak in a wavelength in the range of 650 to 750 nm, and an intensity ratio between 1:0.15 and 0.40 as an intensity ratio of the second emission peak with respect to the first emission peak.12-09-2010
20110074284COMPOSITION FOR PROTECTIVE LAYER OF PLASMA DISPLAY PANEL, PLASMA DISPLAY PANEL AND METHOD OF MANUFACTURING THE SAME - A composition for a protective layer of a plasma display panel includes a metal oxide powder containing a metal selected from Mg, Cu, Ca, Sr, Ba, Zn, Mn, Fe, Al, Ti, Zr, Sn, Ce and combinations thereof, a dispersing agent, and a solvent selected from nitrile compounds, tertiary alkyl acetates, alkylene glycol alkyl ethers, dichloromethane, tetrahydrofuran and combinations thereof. Also, a plasma display panel includes a protective layer formed of the composition for a protective layer, and a manufacturing method thereof.03-31-2011

20100100941CONTEXT-AWARE ROLE-BASED ACCESS CONTROL SYSTEM AND CONTROL METHOD THEREOF - A context-aware role-based access control system and a control method thereof. The context-aware role-based access control system includes: a context-aware user assignment manager (CAUAM) for performing a role assignment function, a role delegation function, or a role revocation function for a user according to a context of the user, based on a preset context request condition; a context-aware permission assignment manager (CAPAM) for performing a permission modification, a permission restoration, and a personalized permission modification for a permission, which the role has, according to changes in the context of the user; an information repository for storing a user profile and context information; and an access control manager (ACM) for controlling the context-aware user assignment manager, the context-aware permission assignment manager, and the information repository, and processing an access control request. Accordingly, more efficient access control can be achieved in ubiquitous environments where the context of the user dynamically changes.04-22-2010
