CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a National Stage Entry of PCT / CN2016 / 074134 filed Feb. 19, 2016, which claims the benefit and priority of Chinese Patent Application No. 201510130819.4, filed on Mar. 24, 2015, the disclosures of which are incorporated by reference herein in their entirety as part of the present application.BACKGROUND[0002]The embodiments of the present disclosure relate to the field of semiconductor fabricating technologies, and particularly, to an organic light emitting device and a method for fabricating the same, and a display apparatus.[0003]The current solution process can fabricate green and red light devices with excellent performances, but there is still a large gap between such fabricated blue light device and the VTE-fabricated blue light device in efficiency or in lifetime. Thus, when the solution process is used to fabricate the full color Organic Light-Emitting Diode (OLED) display, an Open Mask is usually adopted to fabr...

AI Technical Summary

Benefits of technology

The auxiliary layer enhances the performance of the first doped layer, improving the efficiency and reducing the operating voltage of the OLED, while maintaining the same brightness and color characteristics as existing devices.

Problems solved by technology

The current solution process can fabricate green and red light devices with excellent performances, but there is still a large gap between such fabricated blue light device and the VTE-fabricated blue light device in efficiency or in lifetime.

Usually both sides of an interface between the blue light emitting layer and the solution process light emitting layer are doped layers, and the process modes of the first and second doped layers are different from each other, which will easily cause the problems such as efficiency decrease.

In the current OLED having a blue light common layer, such an interface is not efficiently improved, and thus the performance of the OLED is certainly affected.
