Abstract
The invention discloses glass powder for an ADD electrode of a plasma display panel back plate. The glass powder is characterized in that the glass powder comprises the following components, by weight, 60-70% of PbO, 5-15% of Bi2O3, 0-10% of B2O3, 0-1% of Al2O3, 20-30% of SiO2, and 0-5% of TiO2. The purposes of the present invention is to overcome the defects in the prior art, and provide the glass powder for the ADD electrode of the plasma display panel back plate, wherein the glass powder has advantages of high breakdown voltage, suitable thermal expansion coefficient, good compatibility with the electrode, and no fracture phenomenon after sintering.
Description
Technical field
The present invention relates to the ADD glass for electrode powder of plate behind a kind of plasma panel.
Background technology
In recent years; Along with improve constantly the progress with science of human consumer to the display device functional requirement; Novel flat-plate display devices such as PDP, LCD have appearred; Advantages such as they are high, in light weight with its sharpness, little power consumption, radiationless, good environmental protection; Get into people's social life field more and more, show its advantage in national defence, the development of the national economy and family, office, various public place day by day, particularly the PDP technology has its absolute predominance in the flat-panel display device of jumbotron.The whole world has got into the FPD epoch.
The technical characterictic that PDP (PDP) is different from other image display is to have utilized gas discharge principle; Image display is made up of two substrates up and down; Wherein, Hypocoxa comprises barrier, fluorescent material, back medium layer and Add electrode, and upper substrate comprises resist, front medium layer and BUS electrode, and upper and lower base plate is used the sealing-in low glass powder.
The ADD electrode is claimed site selection electrodes again, and back medium layer is to be produced on the ADD electrode of back glass substrate, thereby this electrode will have good matching with the back medium, and will in metal electrode, add fusion, with contact substance form assisted sintering.
Summary of the invention
The objective of the invention is in order to overcome weak point of the prior art, a kind of higher breakdown voltage resistant, suitable thermal expansivity that has is provided, good with the electrode compatibility, the ADD glass for electrode powder of plate behind the plasma panel of non-cracking phenomenon behind the sintering.
