We propose double-faced organic light-emitting diodes (OLEDs) of a dual drive and emission (DDE) panel. Two OLEDs with two transparent electrodes for data signals and an intermediate reflective electrode for the common scan signal are independently operated. The typical structure of a stacking device is transparent electrode (1)/organic layer (1)/interlayer electrode/organic layer (2)/transparent electrode (2) on a glass substrate. Symmetric bright emission could be obtained using AlNd as the interlayer electrode and MoO3 as the hole injection layer for the upper OLED. The proposed device is useful for emissive double-faced panels displaying different images.
