1. A gate driver for providing a gate drive signal for a thin film transistor array substrate, the gate driver comprising:

  • a driving capability detector configured to receive at least the gate drive signal and to detect a driving capability of the gate drive signal based at least on the gate drive signal, the driving capability being represented by a rising time taken by the gate drive signal in form of a voltage pulse signal to rise from a low level to a high level, wherein the driving capability detector is further configured to output a detection signal indicative of the driving capability to an external controller;

    a register configured to receive and store an adjustment instruction in form of a digital signal from the external controller;

    a push-pull output circuit comprising a first MOS transistor and a second MOS transistor connected in series; and

    a driving capability adjustor connected in series with the first and second MOS transistors and between the first and second MOS transistors, wherein the driving capability adjustor is configured to adjust the driving capability of the gate drive signal in response to the adjustment instruction stored in the register.
