The image demonstrates the bright white color emission from a combination of orange and blue emission using three horizontally oriented phosphorescent dyes, which abstracts a tandem white organic light‐emitting diode (OLED) using exciplex‐forming co‐hosts. J.‐J. Kim and co‐workers report on page 5864 high‐efficiency orange and tandem white OLEDs using horizontally oriented phosphorescent dyes, realizing high external quantum efficiencies.
