| titleOfInvention | Organic light-emitting device, preparation method thereof, and display device |
| abstract | The invention provides an organic light-emitting device, a preparation method thereof, and a display device, which are used for simplifying the structure, improving the light-emitting efficiency and reducing the driving voltage. The organic light-emitting device includes: a first electrode layer and a second electrode layer oppositely arranged, at least two stacked layers arranged between the first electrode layer and the second electrode layer, and each stacked layer at least includes a light-emitting layer; : a single-layered charge generation layer located between any two adjacent stacked layers, each charge generation layer includes: an electron transport material layer containing at least one nitrogen heterocycle, and an electron transport material layer containing at least one nitrogen heterocycle There are n-type dopants and p-type dopants inside. |
