1. A touch display apparatus for realizing touch sensing and displaying, comprising:

  • a first substrate;

    a second substrate arranged opposite to the first substrate, wherein gate lines, data lines and thin film transistors are arranged on a surface of the second substrate facing towards the first substrate;

    a liquid crystal layer arranged between the first substrate and the second substrate;

    a common electrode arranged between the first substrate and the second substrate and used as a touch sensing electrode during a touch sensing stage; and

    a driving circuit configured to provide a first signal to the common electrode for realizing touch detection during the touch sensing stage,wherein the driving circuit is further configured to provide a second signal to the gate line during the touch sensing stage, wherein the second signal is used to control the thin film transistor to be switched off and is used to decrease charge and discharge capacity of a capacitor formed by the common electrode and the gate line; and

    /or the driving circuit is further configured to provide a third signal during the touch sensing stage, wherein the third signal is used to decrease charge and discharge capacity of a capacitor formed by the common electrode and the data line.
