P‐164: Highly Efficient White Organic Light‐Emitting Diodes Using Two Emitting Materials for Three Primary Colors (Red, Green and Blue)

AbstractThese results have demonstrated the highly efficient white organic light‐emitting diodes (WOLEDs) with two separated emissive materials for the three primary colors, red, green, and blue, using blue fluorescent and red phosphorescent dopants. The two devices with the optimum structure showed a maximum luminance of 30500 and 20400 cd/m2 and a luminous efficiency of 38.0 and 32.7 cd/A. Furthermore, device B showed better CIEx,y coordinates of (x=0.36, y=0.35) at 10V. We expect that the WOLEDs fabricated using device structures and materials described here may be applicable for backlights in liquid crystal displays.
