Fabrication of WOLED with orange and blue emissive layers using two complementary color method

WOLED devices were fabricated using two complementary color method with two emissive layers of blue and orange color respectively. WOLED' s color purity was optimized as changing thickness of blue emissive DPVBi layer with most efficient red emissive layer doped with 0.2% DCJTB in Alq3 and obtained better white color coordinates of (0.36, 0.33) at 9V.
