Red OLED Achieves 25.6% EQE Using Selenium-Enhanced Multiple Resonance Design

Researchers have developed a red organic light-emitting diode (OLED) with an external quantum efficiency (EQE) of 25.6%, marking a significant advancement in display technology. The device maintains this high efficiency even at a luminance level of 10,000 cd/m², which is considered exceptionally bright. This achievement results from the integration of selenium atoms into a multiple resonance framework, representing a novel approach in OLED design.

The incorporation of selenium plays a critical role in enhancing the performance of the OLED by improving its light-emission properties. The use of this element within the multiple resonance structure allows for greater energy efficiency and stability under high luminance conditions. Researchers highlight that this breakthrough could pave the way for more efficient and durable display technologies across various applications, including smartphones, televisions, and other electronic devices.
