| 发明名称 | White organic light emitting device | ||
| 摘要 | A white organic light emitting device including an anode and a cathode opposite to each other, a plurality of stacks disposed between the anode and the cathode, each of the stacks including a hole transport layer, a light emitting layer and an electron transport layer, and an n-type charge generation layer and a p-type charge generation layer disposed between different adjacent stacks, wherein the n-type charge generation layer includes a first organic host, and the p-type charge generation layer includes a second organic host having a LUMO energy level smaller than or equal to a LUMO energy level of the first organic host, and an inorganic dopant containing 1% to 20% by volume of a metal. | ||
