An organic light emitting diode display and a driving method thereof are provided to prevent non-uniform brightness by increasing the sensing accuracy of a threshold voltage of a driving TFT through a simple scheme. In an organic light emitting diode display and a driving method thereof, an anode electrode of an organic light-emitting diode is connected to a high potential drive voltage source(VDD). A cathode electrode is commonly connected with a drain electrode(D) and a threshold voltage compensating circuit(130) of the drive TFT(DR). A gate electrode(G) of the drive TFT is connected to the compensating threshold voltage circuit via the first node(n1). |
