Abstract
A shift register, a gate drive circuit, a display apparatus and a driving method of the shift register are provided. The shift register includes an input subcircuit, a first and a second output subcircuits, a trigger signal input terminal, a first and a second signal output terminals, a first and a second clock terminals and a pull-up node, a control terminal and an output terminal of the input subcircuit are electrically coupled to the trigger signal input terminal and the pull-up node, respectively, for providing a valid signal received by the control terminal of the input subcircuit to the pull-up node. The shift register is provided with the first and second output subcircuits which share the same input subcircuit, greatly reducing the number of devices and thus greatly simplifying the structure of the cascaded shift registers and reducing the area of the whole display apparatus.
