Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A novel all‐phosphor, four‐color, white organic lightemitting diode (WOLED) architecture is presented that utilizes molecular energy transfer or, specifically, triplet exciton down conversion within common organic layers in a cascaded emissive zone configuration. As reported by Yi‐Lu Chang, Gregory D. Scholes, Zhenghong Lu, and co‐workers <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">on page 705</ext-link>, exceptional performance combinations of external quantum efficiency and color rendering index are achieved. This represents a significant step towards the realization of WOLEDs in solid‐state lighting. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1ts4sbqm" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
