Glass Frit


for AMOLED panel & OLED Light


YEK Glass offers a large range of glass frit products.

Glass frit powder and paste is used as inorganic sealant in order to seal AMOLED and OLED panels. A glass-based seal will reliably protect them from moisture and air, creating what some call a “Perfect Seal”. Our products feature superior laser absorption, high sealing strength and printability, which is ideal for low temperature local heat sealing.

Application AMOLED, OLED Light etc.
