Abstract

A gate driving unit and a driving method for the same, a shift register circuit, and a display apparatus, and an operating period of the gate driving unit comprises a first and a second sub-period; a first pull-down node control module in the gate driving unit causes a first pull-down sub-node to be at an inactive level in the second sub-period, and causes the first pull-down sub-node to be at an active level during a reset phase in the first sub-period; a second pull-down node control module causes a second pull-down sub-node to be at an inactive level in the first sub-period, and causes the second pull-down sub-node to be at an active level during a reset phase in the second sub-period. It is possible to shorten the turn-on time of transistors controlled by the first and the second pull-down sub-nodes, and improve the reliability of the gate driving unit.
