Document Type and Number:
WIPO Patent Application WO/2024/082939
Kind Code:
A1
Abstract:
The present disclosure belongs to the technical field of display. Provided are a light-emitting device, a display substrate and a display apparatus. The light-emitting device of the present disclosure comprises a first electrode and a second electrode, which are arranged opposite to each other, and at least two layers of light-emitting units, which are arranged between the first electrode and the second electrode and are arranged in a stacked manner. The light-emitting device further comprises charge generation units, which are arranged between adjacent light-emitting units, each charge generation unit comprising a first charge generation unit and a second charge generation unit, which are sequentially arranged in a direction from the second electrode to the first electrode, wherein the material of the first charge generation unit comprises a first host material and a first guest material, which is doped in the first host material, the first charge generation unit is configured to generate first charges, and the first guest material is configured to absorb light, which is emitted by the light-emitting units, so that the first charge generation unit generates the first charges.
