Universal Display (UDC) logoUniversal Display Corporation and Nippon Steel Chemical today announced a new PHOLED emitter material from Universal Display, called UDC-RD39, and the exciting collaborative results of combining this new emitter material with NSCC's commercial NS11 host material.

When combined with NS11, this new bright-red PHOLED emitter, with CIE coordinates of (0.65, 0.35), exhibits a luminous efficiency of 24 candelas per Ampere (cd/A), corresponding to a 19% external quantum efficiency, at 1000 candelas per square meter (cd/m2). Under accelerated testing conditions, this new red emitter demonstrates an operating lifetime of approximately 220,000 hours, at an initial luminance of 1000 cd/m2. These dramatic performance gains represent a 60% increase in luminous efficiency and five-fold increase in lifetime, as compared to Universal Display's first-generation commercial red PHOLED emitter. As a result, Universal Display's second-generation emitter in combination with NSCC's host material may be well suited to meet the performance requirements for TV and other demanding product applications.
