Abstract
There are disclosed a shift register unit (100) and a driving method thereof, a gate driving apparatus and a display apparatus. The shift register unit (100) comprises a scanning direction selection unit (101), a control unit (102), a bootstrap unit (103), a first pull-down maintenance unit (104) and a second pull-down maintenance unit (105), which are used to reduce electric stress of a part of elements in the shift register unit (100), so as to raise stability of operation and prolong service life. Additionally, it is capable of realizing a narrow frame design of a liquid crystal display. The gate driving apparatus can adopt the GOA technique to enhance integrity of the TFT-LCD panel.
