LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18193218 titled 'LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME
Simplified Explanation
The patent application describes a light-emitting device that includes a first electrode, a second electrode, and an interlayer between them. The interlayer contains an emission layer, which consists of a first emission layer with a first quantum dot and a p-type compound, and a second emission layer with a second quantum dot and an n-type compound. The second emission layer is positioned towards the first electrode, which serves as the cathode.
- The light-emitting device includes a first electrode, a second electrode, and an interlayer with an emission layer.
- The emission layer consists of a first emission layer with a first quantum dot and a p-type compound.
- The emission layer also includes a second emission layer with a second quantum dot and an n-type compound.
- The second emission layer is positioned towards the first electrode, which is the cathode.
