UDC announces the new OLEDX architecture to improve OLED light output

Universal Display Corporation announced a new OLED architecture, called OLED^X, that improves how light is extracted and utilized within an OLED device, while offering more control over the light output for display makers. The company says that this architecture, according to its laboratory results, represent one of the most significant advances in OLED energy efficiency since the invention of phosphorescent OLED technology.

Even though OLED devices are very efficient, most of the light get trapped or lost within the device. UDC says that the new OLED^X architecture opens a path to extract 100% of the light form an OLED (i.e. reach 100% EQE), enables ultra-wide viewing angles, and increases the design freedom as it unlocks customizable efficiency and viewing angle profiles for significant power saving and/or viewing benefits across form factors.

The new OLED^X architecture makes use of a transparent cathode, reflective anode, and nanoparticle outcoupling layer, to recover light otherwise trapped in the device. OLEDX is actually part of UDC's long-term device architecture roadmap, which includes Plasmonic OLED and Polariton-Enhanced Purcell (PEP), two technologies that the company is developing in order to increase effiiciency, lifetime and optical performance even further in the future.
