An efficient double‐sided emitting OLED employing a stacked geometry has been fabricated. It uses a reflective composite silver electrode as the middle reflective layer. It can be used in a passive matrix (PM) driving scheme with independent control of both displays. Superior electroluminescent (EL) performance of the OLED on both (“bottom” and “top”) sides can be easily achieved without interference independently. The power efficiencies at 100 cd/m 2 of bottom‐ and top‐emitting OLEDs are 10.3 lm/W and 12.1 lm/W, respectively.
