Patent ID: 7679093

Claim:
A dual emission organic light emitting display device comprising: a top emission organic light emitting diode having a top first electrode, a top organic layer and a top second electrode, the top organic layer being disposed between the top first electrode and the top second electrode; a bottom emission organic light emitting diode having a bottom first electrode, a bottom organic layer and a bottom second electrode, the bottom organic layer being disposed between the bottom first electrode and the bottom second electrode; a pixel driver adapted to generate a top driving current and a bottom driving current; and a top/bottom selector comprising a top emission transistor connected between the pixel driver and the top first electrode of the top emission organic light emitting diode and adapted to turn on or off in response to the top emission control signal, and a bottom emission transistor connected between the pixel driver and the bottom first electrode of the bottom emission organic light emitting diode and adapted to turn on or off in response to the bottom emission control signal.
