Abstract
The present disclosure provides a drift control circuit, a drift control method, a gate driving unit, a gate driving method and a display device. The drift control circuit includes: a first drift control sub-circuit configured to, during noise releasing performed by the first pull-down module, control first electrodes of pull-down transistors included in the second pull-down module to be coupled to a first control voltage terminal, which is configured to input a first voltage to the first pull-down module during noise releasing performed by the first pull-down module; and a second drift control sub-circuit configured to, during noise releasing performed by the second pull-down module, control first electrodes of pull-down transistors included in the first pull-down module to be coupled to a second control voltage terminal, which is configured to input the first voltage to the second pull-down module during noise releasing performed by the second pull-down module.
