Polarized white electroluminescence from WOLEDs with a reflective polarizer and a quarter wave plate film

摘要

We present a highly polarized WOLEDs using a quarter-wave plate film and a reflective polarizer, which exhibited emissions of 14,000 cd/m~2 with peak efficiency of 18 cd/A and degree of polarization over 35. These are almost two times higher than those of the polarized WOLED using only a polarizer.
