Novaled showcase new materials to improve efficiency and lifetime for OLED-Tv and mobile displays
Novaled introduce new OLED materials at the SID-2012 event.
The company announces a new class of n-doped electron transport layer (ETL) materials for OLED TV and OLED mobile displays. By pairing either of its two new air-stable dopants with either of its two new host molecules, Novaled can achieve the optimum combination of efficiency, voltage and lifetime for a specific display application. This innovative approach results in materials that are air-stable and can double the lifetime of the display compared to the previous OLED stack. The new materials are the next step toward achieving an optimum balance between long lifetime and high power efficiency for display applications using OLEDs.
Novaled will highlight its recent advances in OLED display and OLED lighting at the Society for Information Display’s (SID) 49th annual International Symposium & Exhibition, “Display Week 2012,” June 3 – 8, 2012, in Booth #3313 at the Boston Convention and Exposition Center, Boston. Dr. Jan Birnstock, Vice President Technology & Products at Novaled, will present a paper on June 6 about Novaled’s new class of OLED materials for OLED TV and OLED mobile display applications. Dr. Sven Murano, Product Senior Manager at Novaled, will present a paper on June 7 about Novaled’s outcoupling materials for high-efficiency white OLEDs – light extraction crucial for both lighting and display applications.
Optimized OLED Lifetime and Efficiency Performance
Novaled’s new generation of materials includes NET-164 and NET-142 hosts, and
NDN-77 and NDN-87 ETL dopants. Using various combinations of these dopants and hosts, Novaled can optimize OLED performance for lifetime or efficiency, depending on application requirements. Thus the new generation material addresses two previous OLED weaknesses:
· Low driving voltage caused lower lifetime due to higher charge carrier density in the emission zone.
· Air-sensitive N-side dopant materials required more complicated loading in mass production tools.
Effective Outcoupling for Better Light Efficiency
To achieve maximum efficiency in white PIN OLED devices, Novaled uses evaporation processable outcoupling layers – thin NET-61 layers in n-doped ETLs. The use of crystallizing outcoupling enhancement layers leads to corrugation of the reflective cathode, significantly reducing the plasmon absorption losses. Novaled has deepened its expertise on effective outcoupling and, during its presentation on June 7, will introduce its latest data about a three-unit white stacked PIN OLED using NET-61.
