Abstract: A method for making phosphor ink is provided which uses ultrasonic vibrations to remove surface defect layers from phosphor particles and to quickly and uniformly disperse the phosphor particles throughout a slurry. Propagation of low frequency vibration through the slurry generates cavitation, causing distortion and then removal of the surface defect layer, and propagation of high frequency vibration through the slurry causes the particles to be dispersed quickly and uniformly throughout the slurry. In this manner, a quantity of light generated in the phosphor and corresponding luminance of a PDP is increased.

Abstract: In a method for making phosphor ink and a system using the same, by generating ultrasonic vibrations, phosphor particles mixed in a slurry can be dispersed, and surface defect layers formed on the phosphor particles can be removed. Accordingly, the method for making phosphor ink and the system using the same are capable of increasing a quantity of light generated in the phosphor, increasing luminance of a PDP and dispersing phosphor particles quickly and uniformly.

Abstract: A thermal evolving method and apparatus for a plasma display panel method that is adaptive for reducing a noise as well as a thickness of the plasma display panel. In the method and apparatus, at least one of a Peltier effect and a Thomson effect is used to refrigerate the plasma display panel.

Abstract: A composition of barrier rib material that is capable of improving a strength of a barrier rib. The composition of barrier rib material includes a barrier rib material paste and a fiber material having a certain tensile strength, thereby increasing the compressed strength and the tensile strength of the barrier rib.
