Abstract:
A novel black matrix, a method for preparing the same, and a flat display device and an electromagnetic interference filter to which the black matrix is applied. The black matrix is prepared by exposing a photoactive compound to form a latent pattern of nuclei for crystal growth and treating the latent pattern of nuclei for crystal growth with a metal salt solution to give a metal particle-deposited pattern; forming an electroless Ni-plated layer on the metal particle-deposited pattern; and forming an electroless Cu-plated layer on the electroless Ni-plated layer. Exhibiting improved black tone, which is achieved only by a selective multilayer plating process, without using expensive vacuum sputtering apparatus or a photolithographic process, the black matrix can be applied to various flat display devices. In addition, due to improved electric conductivity, the black matrix can be used in an electromagnetic interference filter, without employing an additional front surface blackening process.
Abstract:
A plasma display panel for improving a color coordinates correction and a color temperature is disclosed. In the plasma display panel, a vertical barrier rib separates red, green and blue discharge cells from each other in a longitudinal direction. A horizontal barrier rib is provided between the vertical barrier ribs to separate the red, green and blue discharge cells from each other in a wide direction. The horizontal barrier rib has a first horizontal barrier rib provided between the red discharge cells, a second horizontal barrier rib provided between the green discharge cells, and a third horizontal barrier rib provided between the blue discharge cells and having a smaller width than the first and second horizontal barrier ribs.

Abstract:
A method of forming a protection layer of a plasma display panel, which has upper electrodes, lower electrodes and a barrier rib, includes the steps of: forming a dielectric layer on the upper electrodes; and forming a MgO protection layer on the dielectric layer by the method of direct coating the MgO solution on the surface of the dielectric layer. Some advantages are derived by properly mixing MgO particles, salt containing Mg, and organic binder and coating an MgO protection layer (thin film) on the surface of the PDP substrate irrespective of coating methods by simple facility and processing. These advantages include PDP MgO protection layer formation to reduce PDP production cost, time and firing voltages, and adjustment of the protection layer's thickness.
