An organic electroluminescent device and its preparation method and display device |
| abstract |
The present invention provides an organic electroluminescence device, a preparation method thereof, and a display device. The organic electroluminescence device includes a light-emitting layer, the light-emitting layer includes a host material and a dye, and the host material is a triplet-triplet annihilation material, The dye includes a thermally activated delayed fluorescent material; the singlet energy level of the triplet-triplet annihilation material is greater than the singlet energy level of the thermally activated delayed fluorescent material; the triplet energy level of the triplet-triplet annihilation material is smaller than that of the thermally activated delayed fluorescent material. Triplet energy levels of activated delayed fluorescent materials. The invention can overcome the defect of short device lifetime caused by high-energy excitons in the device at the present stage. |
