%X We report a white tandem organic light-emitting device (TOLED) with high efficiency and low drive voltage using Bphen:Li/WO3 as the interconnecting layer.The TOLED have been fabricated by connecting two low-voltage driving white units with conductive transport layers.The tandem two-unit device produces two higher luminance efficiency than that expected of a single-unit device.A maximum efficiency of 17cd/A is achieved by the tandem device comprised of two white-fluorescent OLEDs.The power efficiency of tandem white organic light-emitting device is enhanced by 53% as compared to the control device.
