With electrode material with high reflectivity come as driving electrodes.However, the electrode of high reflectance often has high reaction activity,
It is easy to be influenced and reduced the service life of Organic Light Emitting Diode by extraneous aqueous vapor and oxygen.Therefore, existing organic light emission
Diode display also needs strict encapsulation procedure to avoid extraneous aqueous vapor and oxygen from entering simultaneously.It is most currently used
Be upper and lower base plate using glass substrate as Organic Light Emitting Diode, and reduce aqueous vapor and oxygen using the glass substrate
Penetrance, it is ensured that the service life of organic light-emitting diode element and quality.However, if it is considered that whole weight, thickness, even
It is the following bendable application, just inevitably needs use plastic substrate, but will be reduced and be blocked using plasticity machines plate
The ability of aqueous vapor and oxygen penetration, and then reduce service life and the quality of Organic Light Emitting Diode.
