ANTIMONY-FREE GLASS, ANTIMONY-FREE FRIT AND A GLASS PACKAGE THAT IS HERMETICALLY SEALED WITH THE FRIT

摘要

An antimony-free glass comprising TeO2 and/or Bi2O3 suitable for use in a frit for producing a hermetically sealed glass package is described. The hermetically sealed glass package, such as an OLED display device, is manufactured by providing a first glass substrate plate and a second glass substrate plate and depositing the antimony-free frit onto the first substrate plate. OLEDs may be deposited on the second glass substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first glass substrate plate to the second glass substrate plate and also protects the OLEDs disposed therein. The antimony-free glass has excellent aqueous durability, good flow, and low glass transition temperature.
