Provided are an AMOLED drive circuit, a drive method and a display apparatus. The AMOLED drive circuit comprises: a control unit, a charging unit, a drive unit and a light-emitting device, wherein the control unit is connected to a data line and a control line, and the control unit is connected to the drive unit via a first node, a second node and a third node; and the charging unit is connected to the drive unit via the first node, the charging unit is connected to a first power source, the drive unit is connected to one end of the light-emitting device, the drive unit is also connected to the first power source, and the other end of the light-emitting device is connected to a second power source. When a first control signal flows through the control line, in response to the first control signal, the control unit controls the current from the data line to charge the charging unit through the drive unit; and when a second control signal flows through the control line, in response to the second control signal, the control unit controls the charging unit to provide a drive voltage for the drive unit via the first node, so that the drive unit drives the light-emitting device to emit light after being driven by the drive voltage. The problems of slow charging speed and long charging time of an AMOLED drive circuit on a capacitor can be effectively solved, so that the AMOLED drive circuit is applicable to AMOLED display at high resolution and high refresh frequency. |
