제목 Enhanced Light Outcoupling in Down-Conversion White Organic Light-Emitting Diodes Using Imprinted Microlens Array Films
초록 We demonstrate high performance down-conversion microlens array (DC-MLA) films for white organic light-emitting diodes (OLEDs). The DC-MLA films are readily fabricated by the imprinting method based on breath figure patterns and result in high quality white light as well as enhanced light outcoupling efficiency of white OLEDs. The external quantum efficiency of OLEDs with DC-MLA films is increased by a factor of 1.44 compared to OLEDs without outcoupling films. Moreover, the white OLEDs with DC-MLA films achieve a high color rendering index of 84. It is anticipated that the novel DC-MLA films fabricated by a simple imprinting process with the breath figure pattern can contribute to the development of efficient white OLEDs.
