玻璃后盖对有机电致发光器件封装性能的影响
Effect of Cover Glass on OLED Encapsulation Performance
摘要
Abstract
Cover glass for OLED encapsulation was made by wet etching technology. The impact of concentration of hydrofluoric acid, temperature, ultrasound and reactant on thickness and surface smoothness was studied. The best method to make cover glass was obtained: In the ultrasonic cleaner, the concentration of hydrofluoric acid was 40%, corrosion time was 15 min and the corrosion process cleared the reactant, then we got 0. 177 mm smooth surface cover glass, which was coincident with the encapsulation standard of organic electroluminescent devices. Organic Light-Emitting Diodes were encapsulated using cover glass made by this method in a nitrogen atmosphere, the attenuation rate of luminance of these devices can be slowed down.关键词
