Abstract
Provided is a dual pull-down control module including a signal input terminal, a pull-down signal output terminal, and a clock input terminal. The dual pull-down control module further includes: a control subunit, of which a first terminal is connected to the signal input terminal; a fifth thin film transistor, of which a gate is connected to a second terminal of the control subunit, a first pole is connected to a third terminal of the control subunit, and a second pole is connected to the clock input terminal; and a unidirectional turn-on element, of which a first terminal is connected to the third terminal of the control subunit, a second terminal is connected to the second pole of the fifth thin film transistor. The unidirectional turn-on element is turned on when a level at the first terminal thereof is higher than a level at the second terminal thereof.
