LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17833946 titled 'LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME
Simplified Explanation
The patent application describes a light-emitting device and an electronic apparatus that includes the device. The device consists of a reflective electrode, a second electrode, and an emission layer between them. The emission layer can include a first emission layer, a second emission layer, or both. The first emission layer emits light with a specific spectrum, while the second emission layer emits light with a different spectrum. The emission layer can also emit a third spectrum of light. The wavelengths of the emission peaks of the different spectra have specific relationships to each other.
