According to the present invention, there is discussed an organic light-emitting diode display device. More particularly, the present invention relates to an organic light-emitting diode display device for minimizing power consumption in a standby mode in which no images are displayed but not in a normal mode in which typical images are displayed, and a driving circuit and method thereof. An organic light-emitting diode according to an embodiment of the present invention may control a drain-source voltage (VDS) of the drive transistor provided in the pixel, thereby having an effect of capable of minimizing power consumption when in a standby mode.
