| titleOfInvention | An organic electroluminescent device |
| abstract | The invention provides an organic electroluminescence device, which belongs to the technical field of organic electroluminescence. In the organic electroluminescent device provided by the present invention, the hole blocking layer and the electron blocking layer are respectively arranged on both sides of the light emitting layer, so that the HOMO-LUMO state density of the hole blocking layer and the electron blocking layer is compared with the HOMO-LUMO state density of the host material of the light emitting layer. The overlap between LUMO state densities (such as the overlap ratio) is adjusted to a predetermined range, which can effectively avoid the leakage of electrons/holes moving or diffusing to adjacent organic layers when holes/electrons accumulate in the light-emitting layer. , so that the holes/electrons are effectively confined inside the light-emitting layer to form exciton emission, and the exciton recombination region moves to the center of the light-emitting layer, thereby improving the luminous efficiency of the organic electroluminescent device and prolonging the use of the device. life. The organic electroluminescence device has good application effect and industrialization prospect. |
