An organic light emitting diode (OLED) display device and a method for driving the OLED display device are provided. A gate drive circuit provides scan signals in sub-frames to scan lines. A data drive circuit provides a data signal to data lines. An emission control signal generation circuit provides first and second emission control signals to control the OLEDs. A display region includes pixels arranged in a matrix and connected to the scan lines, data lines, emission control lines, and power lines. The pixels include a first and a second unit pixel portion. The first unit pixel portion performs a time division control drive by driving a plurality of organic light emitting diodes by one shared pixel circuit. In the second unit portion one organic light emitting diode is driven by an independent pixel circuit.
