Abstract: A pixel of an organic light emitting diode display device includes a switching transistor which transfers a data voltage in response to a scan voltage applied thereto through a scan line, a storage capacitor which stores the data voltage transferred by the switching transistor, a driving transistor which generates a driving current based on the data voltage stored in the storage capacitor, an organic light emitting diode which emits light based on the driving current, and an anode discharging capacitor connected between the scan line and an anode of the organic light emitting diode.

Abstract: A display device includes a liquid crystal display and a power supply to apply a common voltage to a common electrode of the display. The power supply applies a first common voltage to the common electrode for a first period after power is turned on, and applies a second common voltage higher than the first common voltage to the common electrode until the power is turned off after the first period.
