Gate driving circuit, an array substrate and a method for recovering the same

A gate driving circuit, comprising:

• a plurality of cascaded shift registers, wherein each stage of the shift register has a signal outputting terminal connected with a corresponding gate line, and the signal outputting terminals of the rest stages of shift registers other than a shift register in a first stage and a shift register in a last stage are connected with a resetting signal terminal of the shift register in a previous stage and a signal inputting terminal of the shift register in a next stage, respectively;
• a recovering signal line and a first reference signal line, extending along an arrangement direction of the plurality of cascaded shift registers;
• and
• a plurality of recovering units, corresponding to the plurality of cascaded shift registers respectively, wherein each recovering unit has a signal input connectable with the first reference signal line, a signal output connectable with the gate line corresponding to its corresponding shift register, and a signal control connectable with the recovering signal line;
• wherein upon recovering a failed shift register, the recovering unit corresponding to the failed shift register is configured to deliver a first reference signal provided from the first reference signal line to the corresponding gate line, under the control of the recovering signal line.
