An AMOLED display and a drive method therefor. A display panel (100) of the AMOLED display is provided with multiple multiplexers (120). A control end of each multiplexer (120) accesses a multiplex control signal (Mux_ctrl), a first input end is electrically connected to a gate driver (200), a second input end is connected to a constant voltage low potential (VGL), and a first output end and a second output end are respectively connected to a first control end and a second control end of a corresponding row of sub-pixel drive circuits (100). When the AMOLED display is driven, the multiplexer (120) receives a scanning signal transmitted by the gate driver (200) and enables the first output end to selectively output the scanning signal (Gate) or the constant voltage low potential (VGL) and the second output terminal to selectively output the constant voltage low potential (VGL) or the scanning signal (Gate) under the control of the multiplex control signal (Mux_ctrl), so as to generate two different control signals outputted to the first control end and the second control end of the corresponding row of sub-pixel drive circuits (110). The number of output channels of the gate driver (200) can be effectively reduced, and product costs can be reduced.
