Color variation improvement by introducing double emission layers in WPLEDs
Source abstract
Abstract
AbstractWhite polymeric light‐emitting devices (WPLEDs) have been fabricated from polyfluorene‐based (PFO) blue and MEHPPV polymer blending systems. A device structure of ITO / PEDOT:PSS / Blending polymer / Blue polymer / LiF / Al was employed. This structure of double emission layers showed significant improvement of white color shift phenomenon. A current efficiency of 4.67 cd/A (3,900 cd/m2, 6.4 V) and a brightness value of 17,600 cd/m2 at 9.4 V with (0.34, 0.35) CIE coordinates at 5 V and (0.29, 0.29) at 9 V were achieved achieved.
