The present invention discloses an OLED driving device, including a first switch transistor, a first transistor, a second switch transistor, a storage capacitor and a second transistor. The first switch transistor is used to receive a data signal, and output the data signal by the control of a first scan signal. The first transistor is used to compensate the effect of the threshold voltage of the second transistor. The second switch transistor is used to receive a voltage signal, and output the voltage signal by the control of a second scan signal. The storage capacitor is used to store a data voltage. The second transistor is electrically connected to the second switch transistor through the storage capacitor. The present invention can efficiently release the charges from the storage capacitor, enhance display effect, and change the input voltage level for adapting different operating voltages of integrate circuits.
