Abstract:
The present disclosure provides a gate driving circuit and a display apparatus, wherein the gate driving circuit comprises a shift register (10) including a plurality of shift register units connected with each other sequentially, and the gate driving circuit further comprises: a first strobe module (20) and/or a second strobe module (30); the first strobe module (20), connected to a gate scanning trigger signal line (STV) and strobe signal lines (CS0, CS1); the second strobe module (30), connected to the strobe signal lines. With incorporation of the first strobe module (20), a gate scanning trigger signal on a gate scanning trigger signal line (STV) is supplied to a predetermined shift register unit according to strobe signals provided on the strobe signal lines (CS0, CS1); and the second strobe module (30), which is configured to cut off communication between the predetermined shift register unit and its previous stage of shift register unit according to the strobe signals provided on the strobe signal lines (CS0, CS1), so that the shift register is turned off from the predetermined shift register unit, and thus it can be achieved on a liquid crystal display panel that the gate signal(s) in a black-scan area are selectively turned off in a partial display mode, thus power consumption of the whole display panel being reduced.
