LIGHT EMITTING DEVICE AND DISPLAY DEVICE COMPRISING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17900176 titled 'LIGHT EMITTING DEVICE AND DISPLAY DEVICE COMPRISING THE SAME
Simplified Explanation
The abstract describes a light-emitting device that consists of two electrodes, multiple emission parts, and charge generating layers.
- The device includes a first electrode and a second electrode that overlap each other.
- There are multiple emission parts positioned between the first and second electrodes.
- Between each adjacent emission part, there is a charge generating layer.
- Each charge generating layer is composed of an n-type charge generating layer and a p-type charge generating layer.
- The n-type charge generating layer is represented by a compound described in Chemical Formula 1.
Potential Applications:
- Lighting: The light-emitting device can be used for various lighting applications, such as in homes, offices, or public spaces.
- Displays: The device can be utilized in display technologies, including televisions, computer monitors, or mobile phone screens.
