Title:
ORGANIC ELECTROLUMINESCENT DEVICE, OLED SUBSTRATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/219200
Kind Code:
A1
Abstract:
The present disclosure provides an organic electroluminescent device, an OLED substrate and a display device, belonging to the field of display technology, and being able to solve the problems of poor continuity in ink jet printing experiment and requirement for configuring a complex computer program between materials of different luminescent layers, which occur in the process of preparing a current organic electroluminescent device. The organic electroluminescent device of the present disclosure comprises a cathode, an anode and a functional layer located between the cathode and anode; the functional layer comprises a first light-emitting layer and a second light-emitting layer which are sequentially arranged in a direction away from the anode, the first light-emitting layer comprising a first blue light-emitting material, and the first light-emitting layer and the second light-emitting layer forming a composite product after the cathode and the anode are powered on, so as to emit light having a color different from blue.
