A series of white polymer light emitting devices have been fabricated by using a polymer
blending system of polyfluorene-based blue and MEH-PPV red polymers. A device structure of
ITO/PEDOT:PSS/polymer/LiF/Al was employed. The white polymer device exhibited a current
efficiency of 4.33 cd/A (4,816 cd/m2, Q.E. = 1.9 %) and a maximum luminance of 21,430 cd/m2
at 9.2 V. The CIE coordinates were (0.35, 0.37) at 5 V and (0.29, 0.30) at 9 V.
