    Abstract: A pixel of an organic light emitting diode display device includes a capacitor, a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor, a seventh transistor, an eighth transistor, a ninth transistor and an organic light emitting diode. The third transistor includes first and second sub-transistors which are coupled to each other in series between a drain of the first transistor and a gate node, and a fourth transistor includes third and fourth sub-transistors which are coupled to each other in series between a line of an initialization voltage and the gate node. The eighth transistor applies a reference voltage to a first node between the first and second sub-transistors in response to an emission signal, and a ninth transistor applies the reference voltage to a second node between the third and fourth sub-transistors in response to the emission signal.

    Abstract: A display device includes data lines, scan lines, and pixels. Each of the pixels includes an organic light emitting diode, a first transistor (OLED), and a second transistor. The first transistor is electrically connected to an anode of the OLED. The second transistor is electrically connected to the first transistor, a scan line among the scan lines, and a data line among the data lines. The second transistors of the pixels may receive instances of a reference voltage from the data lines during a first period of a frame. The second transistors of the pixels may simultaneously receive instances of a turn-on scan signal from the scan lines during the first period of the frame. Cathodes of the OLEDs of the pixels may receive instances of a turn-off voltage for the OLEDs to turn off during the first period of the frame.
