<p>Lead-free glass powder, lead-free composite glass powder and use thereof, and a display device sealed by using the same, the lead-free composite glass powder comprising lead-free glass powder and a filler; the lead-free glass powder, based on the total weight thereof, comprises: 35%-70% of V2O5, 15%-35% of P2O5, 3%-35% of Sb2O3, 3%-15% of ZnO, and 3%-15% of BaO; and the lead-free composite glass powder does not contain ROHS restricted material, and has a low melting point, a large controllable range of softening temperatures, and a small fluctuation of expansion coefficient, the expansion coefficient of the lead-free composite glass powder satisfying the requirements for sealing between multiple materials. Other oxides and fillers are added, further reducing the preparation cost of the lead-free composite glass powder. In addition, the lead-free composite glass powder increases sealing strength and ensures effective connection between PDP front and back substrates, thus being suitable for sealing the PDP substrates.</p> |
