Abstract
A gate drive unit and a display device in which a plurality of cascaded gate drive circuits are electrically connected to a frequency-division control line configured to transmit a frequency-division control signal, so that a frequency-division control module in each gate drive circuit controls signal transmission between a first power supply terminal and a first node or a second node according to the frequency-division control signal, thereby controlling level states of gate control signals outputted by a first output module and a second output module.
