Application

OLED device is very sensitive to the moisture, black spot will easily occur without proper encapsulation.  A good encapsulation is very necessary for OLED test, including material, efficiency and life, etc. The encapsulation with cover glass, UV-glue and getter can be a simple and reliable process for OLED study.

 

2.Etching Cover

 

For top-emission OLED, light emission will penetrate through the cover glass, so that a sandblasting cover will not suitable due to the scattering of rough surface. Etching cover can provide a smooth surface. It is a better choice for the encapsulation of top-emission OLED.
