Abstract:
The present embodiment of the invention provides a gate driving circuit and a display apparatus using the gate driving circuit. The gate driving circuit has a plurality of shift registers, and each shift register includes a first output unit, a first pull-down unit, a second output unit, a second pull-down unit, a voltage coupling unit, and a voltage boosting unit. The first output unit is coupled to a node and a first output end. The second output unit is coupled to the node and a second output end. The first pull-down unit is coupled to the first output end and a reference potential. The second pull-down unit is coupled to the second output end and the reference potential. The voltage coupling unit is coupled between the node and the second output end. The voltage boosting unit is coupled to a preset potential, the first output end, and a node and a gate high potential of a shift register at a previous stage.
