The manufacturing method and sealing materials for display device that has benn glass transition temperaure is under 300?

摘要

The invention PDP, LCD, LED and VFD of the module a glass frit material as a sealant to be used during production at a low temperature of below 450 relates to a sealant for sealing the face to be fired at a very low temperature below 450 it is to manufacture the glass frit at a low temperature to a technique capable of producing a base. Present case, the sealing is required at a low temperature of less than 450 waejeom Although the majority of the display and using the glass substrate used in the future and a transition point of about 60 soda-lime glass substrate than the low waejeom glass. Therefore, the seal is possible mesh forming agent P with glass frit at low temperatures ₂ O ₅ , B ₂ O ₃ , SnO ₂ in the formula and the intermediate oxide M _X O _Y [M = Al ,, B, Ca, Ba, Zn, Zr, Ti , Li used a], and then mixed with the addition of reducing agent, more than 500 than the former was melted at 900 1400 than at lower temperatures. As a result, SnO _{from 2} -P ₂ O ₅ filler is added as a main component to total around 370 or less (transition temperature below 300 ) After the addition of glass frit and filler as the sealing glass frit 420 was prepared as a sealing hereinafter. In this case, SnO ₂ -P ₂ O ₅ system is mainly a real melting SnO _{2 by using a high of SnO or nitrogen} -P ₂ O ₅ When you type in the 1400 ~ 1500 melting even became a melting crystals produced is determined by the addition of a reducing agent without the atmosphere generate non-transparent glass and developed a low-temperature method that can be melted in a frit.
