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.
