LOW-TEMPERATURE SEALING GLASS FRIT AND METHOD FOR PREPARING COMPOSITE FILLER IN GLASS FRIT

摘要

The invention discloses a lower-temperature sealing glass frit and a method for preparing a composite filler in the glass frit. The lower-temperature sealing glass frit includes a glass powder and a negative thermal expansion composite filler with an adjustable thermal expansion coefficient. The thermal expansion coefficient of the low-temperature sealing glass frit into which the composite material and the glass powder is mixed can be adjustable so that the thermal expansion coefficient of the low-temperature sealing glass frit can match the thermal expansion coefficient of glass substrates packaging an OLED device to thereby improve the yield of the packaged OLED device.
