In this research, we demonstrate a polymer dispersed liquid crystal (PDLC) imprinted microlens array (MLA) via a solution process to improve the out-coupling light efficiency of organic light emitting diode (OLED). MLA and PDLC are excellent technologies for enhancing the out-coupling light efficiency of OLED. The MLA imprinted PDLC applied to OLED improves out-coupling light efficiency by about 22% compared to reference OLED.
