AI Technical Summary

Technical Problem

Existing organic light emitting diodes (OLEDs) face challenges in achieving high efficiency while maintaining excellent viewing angle characteristics and color purity.

Method used

Incorporating two hosts with a difference in ground state dipole moment values of 1.5 Debye or more in the light emitting layer, allowing for increased full width at half maximum and controlled color purity, thereby enhancing the viewing angle and color rendering index.

Benefits of technology

The solution results in improved viewing angle characteristics and color purity, increasing the selection of materials for higher light emitting efficiency and performance.
