AI Technical Summary
Technical Problem
Existing organic electroluminescent devices require further development in structurally optimized organic layers and stable materials to achieve maximum efficiency in the light emitting layer, particularly in terms of energy band gap combinations for efficient hole and electron migration.
Method used
Employing an anthracene derivative as a host and a polycyclic aromatic derivative as a dopant in the light emitting layer, which enhances the device's lifetime and reduces driving voltage.
Benefits of technology
The use of the anthracene derivative and polycyclic aromatic derivative improves the device's lifetime and reduces operating voltage, making it suitable for various display applications.
