Publication number: 20110012095Abstract: An organic light emitting diode (OLED) architecture in which efficient operation is achieved without requiring a blocking layer by locating the recombination zone close to the hole transport side of the emissive layer. Aryl-based hosts and Ir-based dopants with suitable concentrations result in an efficient phosphorescent OLED structure. Previously, blocking layer utilization in phosphorescent OLED architectures was considered essential to avoid exciton and hole leakage from the emissive layer, and thus keep the recombination zone inside the emissive layer to provide high device efficiency and a pure emission spectrum.Type: ApplicationFiled: September 22, 2010Publication date: January 20, 2011Inventors: Vadim ADAMOVICH, Michael Stuart WEAVER, Raymond KWONG
