35.4: Enhancement of Emission Efficiency in White OLED Device by Highly Efficient Narrow Spectrum Red-Emission Material

Newly developed red‐emission material with a narrow spectrum enhanced the current efficiency of a red OLED 1.3 times greater than a conventional material while maintaining chromaticity of red. This material also increased the power efficiency of a white OLED 1.2 times greater than the conventional m...

Zusammenfassung:Newly developed red‐emission material with a narrow spectrum enhanced the current efficiency of a red OLED 1.3 times greater than a conventional material while maintaining chromaticity of red. This material also increased the power efficiency of a white OLED 1.2 times greater than the conventional material without impairing color rendering.
