An AMOLED driving method, comprising:

• in a first stage, turning on a first switching transistor under the control of a first control line, so that a data line provides a voltage to a capacitor through the first switching transistor;
• in a second stage, turning off the first switching transistor under the control of the first control line, and turning off a voltage regulator under the control of the first control line and a second control line, so that the capacitor remains the voltage;
• and
• in a third stage, turning off the first switching transistor under the control of the first control line, and controlling a driving transistor to be turned on by the voltage regulator under the control of the first control line and the second control line, so that the driving transistor drives a light emitting device to emit light.
