ORGANIC LIGHT-EMITTING DEVICE AND PREPARING METHOD THEREOF

WIPO Patent Application WO/2014/082300

A1

An organic light-emitting device (100) comprises a substrate (10), an anode (20), a functional layer (30), a cathode (40), a packaging layer (50) and a packaging cover (60) which are sequentially laminated. The substrate (10) and the packaging cover (60) form a closed space, and the anode (20), the functional layer (30), the cathode (40) and the packaging layer (50) are accommodated in the closed space. The packaging layer (50) sequentially comprises a protection layer (501), an oxygen, nitrogen and carbon compound film (502), an organic barrier layer (503), a moisture absorption layer (504) and a heat dissipation layer (505). The oxygen, nitrogen and carbon compound film (502) is a nitride film doped with oxides and carbides. Also provided is a method for preparing the organic light-emitting device (100). The method can effectively reduce erosion of moisture and oxygen to the organic light-emitting device, so as to effectively protect the organic functional material and electrodes, and significantly improve the service life of the organic light-emitting device. The method is especially suitable for packaging a flexible organic light-emitting device.
