Abstract: Flexible display is one of the important development directions of display technology in the future. Whether organic light-emitting diode (OLED) can realize flexible application depends on the development of film encapsulation technology. This paper first introduces the reasons of failure of OLED devices, the necessity of encapsulation and the requirements for encapsulation, then focuses on introducing and analyzing three methods commonly used for OLED to test water vapor transmittance (WVTR), coulomb method, tritiated water test and Ca corrosion test.

Key words: organic light-emitting diode, water vapor transmittance, coulomb method, tritiated water test, Cacorrosion test
