A dual emission organic light emitting display device and method of
driving the same. The display device includes a pixel driver and an
organic light emitting diode that can display different images on a top
surface and a bottom surface and/or a same image on both the top and
bottom surfaces. The display device includes a top/bottom selector that
receives a driving current from the pixel driver and selectively supplies
the driving current to a top organic light emitting diode or a bottom
organic light emitting diode. The top/bottom selector includes
transistors, which are connected between the pixel driver and the organic
light emitting diode and select a top emission operation or a bottom
emission operation. Here, the circuit configuration of the pixel driver
is reduced so that the dual emission organic light emitting display
device can be improved in terms of a layout, an interconnection, and an
aperture ratio.
