摘要： A pixel circuit and an organic light emitting diode (OLED) display device using the same are provided. The pixel circuit compensates for a threshold voltage of a driver transistor and for a voltage drop, and separately drives an initialization time to improve a contrast ratio. The pixel circuit further suppresses a leakage current caused by a data voltage using a fixed power source so that current variation caused by the leakage current can be reduced or minimized to improve crosstalk, and the duty of an emission control signal can be adjusted to remove motion blur. The pixel circuit also compensates for a leakage current generated in a turn-off state of a transistor with an increase in a drain-source voltage.
