Dopant and non‐dopant OLEDs were fabricated for testing four TADF emitters, having EL of blue to greenish blue color. The tetraphenylbenzene (4Ph)‐containing emitters have been demonstrated having a higher light outcoupling efficiency for dopant devices and a superior IQE for the non‐dopant devices.
