    Abstract: The present disclosure relates to a shift register unit, a driving method thereof, a gate driver on array and a display apparatus. The shift register unit includes a clock control circuit (10), an output control circuit (20) and an output circuit (30). The shift register unit may input clock signals of different frequencies or different duty ratios to the output control circuit (20) and the output circuit (30) respectively via the clock control circuit (10), such that the output circuit (30) can input driving signals of different frequencies or different duty ratios to the pixel units via the output end (OUT) in order to adjust the charging time for each line of pixel units. As a result, the driving manner of the display apparatus by the gate driver on array is enriched, and the driving flexibility is improved.

    Abstract: A gate drive circuit and a display panel are provided. The gate drive circuit controls, by adding a control module, the potential at a key node of an output module in a touch-control phase, that is, outputting a low-level signal of a signal switching end to a first node of the output module of the current-stage shift register in the touch-control phase, so as to stabilise the potential of the key node, i.e. the first node in the touch-control phase, thereby avoiding the case where the potential at the key node is in a floating state and thus is capacitively coupled and deviates from a stable potential; and a transition to a display stage before the touch-control state ends is made, and a high-level signal of the signal switching end is output to the first node, so as to pull up the potential at the first node.
