Universal Display Corporation (UDC) has introduced OLEDX, a new device architecture designed to improve how light is extracted and used within an OLED display, while giving display makers more control over how that light reaches the viewer. UDC unveiled the technology during an invited presentation at the International Meeting on Information Display in Busan, Korea, where the company also shared lab results it describes as one of the most significant advances in OLED energy efficiency since phosphorescent OLED technology was first introduced.
UDC's phosphorescent technology originally transformed the OLED industry by setting a new standard for how efficiently light could be generated inside a display. Since then, one of the industry's most persistent challenges has been getting that generated light actually out of the device and to the viewer's eye, since much of the light produced inside an OLED display ends up trapped or lost before it ever reaches the surface. OLEDX addresses this through a new display architecture that redirects that trapped light into usable output, giving display makers a way to unlock higher efficiency while gaining more control over how light is emitted. UDC says this added flexibility creates new opportunities to improve display performance across applications ranging from smartphones, IT devices, and TVs to next-generation foldable, rollable, and conformable displays.
UDC outlines several key benefits of the technology. On energy efficiency, OLEDX opens a potential path toward extracting 100% of the light generated within an OLED. On image quality, it enables ultra-wide viewing angles without noticeable shifts in color or brightness. And on design flexibility, it allows manufacturers to customize the balance between efficiency and viewing angle performance for different product types, tailoring performance for everything from smartphones and TVs to laptops, tablets, monitors, and automotive displays.
Steven V. Abramson, president and CEO of Universal Display Corporation, said that for more than three decades, UDC has pushed the boundaries of OLED technology by tackling some of the industry's toughest scientific and technical challenges. He said the company's phosphorescent technology transformed the industry by making essentially every electrical charge count, and that OLEDX is designed to make every photon count in the same way. He described OLEDX as addressing one of the industry's longstanding challenges and representing a new platform for advancing display performance, while also strengthening the value of UDC's existing materials and technology portfolio and broadening opportunities to collaborate with customers.
Dr. Julie Brown, executive vice president and chief technical officer at UDC, described OLEDX as the next chapter in OLED efficiency, expanding the design possibilities available to panel makers and giving them more flexibility to optimize display performance for different products and user experiences. She said that by enabling more precise control over how light is emitted from an OLED, the platform creates new opportunities to balance efficiency, image quality, and viewing performance based on what a particular product needs. She also noted that OLEDX was designed with existing OLED manufacturing processes in mind, meaning the industry can evaluate and adopt the technology without needing a fundamentally new production approach.
In his presentation, titled "Next-Generation OLED Platform," Dr. Mike Weaver, vice president and deputy chief technology officer of PHOLED R&D at UDC, explained how OLEDX recovers light that would otherwise stay trapped inside the device, using a transparent cathode, a reflective anode, and a nanoparticle outcoupling layer, layers of the display specifically designed to help light escape more efficiently. He also positioned OLEDX within UDC's broader roadmap for future OLED architectures, which includes ongoing research into Plasmonic OLED and Polariton-Enhanced Purcell (PEP) technology, both aimed at pushing efficiency, lifespan, and optical performance beyond what conventional OLED structures can achieve.
