Universal Display has announced a new light-blue phosphorescent OLED emitter system, suitable for both display and lighting applications. Today they are giving us more information about the new material.
Universal Display’s new light-blue emitter system offers CIE coordinates of (0.17, 0.37) and a peak wavelength of 472 nm. It also provides a luminous efficiency of > 45 candelas per Ampere, corresponding to > 20% external quantum efficiency at 1,000 candelas per square meter (cd/m2). Under accelerated test conditions, this new emitter system demonstrates an operating lifetime of approximately 9,000 hours, to 50% of an initial luminance of 1,000 cd/m2. These performance gains are significant, representing a 30% increase in luminous efficiency and an almost 100% increase in operating lifetime, as compared to Universal Display’s earlier-generation light-blue PHOLED emitter system.
