Abstract
The invention discloses an organic electroluminescent device comprising a dopant material and a plurality of host materials. A light emitting layer of the device includes two host materials having specific structures and a dopant material. Appropriate energy level matching can be obtained by selecting the combination of the specific main body material and the specific doping agent material, the concentration of carriers in the light-emitting layer is effectively regulated and controlled to reach expected balance. Compared with the prior art, the organic electroluminescent device enables the comprehensive performance of the organic light-emitting device to be obviously improved. A display assembly and a compound formulation are also disclosed.
