ORGANIC ELECTROLUMINESCENCE DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18528604 titled 'ORGANIC ELECTROLUMINESCENCE DEVICE
Simplified Explanation
The organic electroluminescence device described in the abstract includes a first electrode, a second electrode, and an emission layer between them. The emission layer consists of a first host, a second host, a first dopant with an organic metal complex, and a second dopant represented by Formula D-2.
- High luminous efficiency and long service life characteristics
- First host and second host are different from each other
- First dopant includes an organic metal complex containing Ir, Ru, Rh, Pt, Pd, Cu, or Os
- Second dopant represented by Formula D-2
Potential Applications
The technology could be applied in:
- Display screens
- Lighting fixtures
- Signage
Problems Solved
- Low luminous efficiency in traditional electroluminescent devices
- Short service life of organic electroluminescence devices
Benefits
- High luminous efficiency
- Long service life
- Energy-efficient lighting solutions
Potential Commercial Applications
- Consumer electronics
- Automotive lighting
- Architectural lighting
Possible Prior Art
Prior art in the field of organic electroluminescence devices may include patents or research papers on improving luminous efficiency and service life of such devices.
