P‐123: Double Emitting Layer Structure for high efficiency and ultra‐stable blue Triplet‐Triplet Annihilation OLED

By using the double emitting layer (DEML) structure in a blue triplet‐triplet annihilation organic light‐emitting diode (TTA‐OLED), maximum external quantum efficiency (EQEmax) of 16.1% with CIE coordinates of (0.135, 0.188) and half‐lifetime of 224,000 hours at initial luminance of 1,000 cd/m2was a...

Zusammenfassung:By using the double emitting layer (DEML) structure in a blue triplet‐triplet annihilation organic light‐emitting diode (TTA‐OLED), maximum external quantum efficiency (EQEmax) of 16.1% with CIE coordinates of (0.135, 0.188) and half‐lifetime of 224,000 hours at initial luminance of 1,000 cd/m2was achieved. The degradation mechanism of TTA‐OLEDs was also investigated by conducting photoluminescence degradation experiment.
