Title:
A COMBINATION OF A HOST COMPOUND AND A DOPANT COMPOUND
Document Type and Number:
WIPO Patent Application WO/2015/046916
Kind Code:
A1
Abstract:
The present invention relates to a specific combination of dopant compounds and host compounds. By using a combination of the dopant and host compounds according to the present invention, an organic electroluminescent device has improved current efficiency compared with conventional light-emitting material, and thus has improved power efficiency at a low driving voltage.
