    Abstract: An organic light emitting display device includes a plurality of pixels. A pixel on an ith horizontal line includes a first transistor coupled between a first power source and a first node and having a gate electrode coupled to a second node. An organic light emitting diode is coupled between the first node and a second power source. A second transistor is coupled between the second and third nodes and is turned on when a first scan signal is supplied to an ith first scan line. A third transistor is coupled between the third and first nodes. A first capacitor is coupled between an ith control line and the second node. A second capacitor is coupled between the third node and a data line. The pixels are simultaneously driven during first, second, and third periods of a frame period and sequentially driven during a fourth period of the frame period.
