1. A touch display device comprising:

  • a first substrate and a second substrate disposed opposite to each other;

    wherein a touch functional layer and a conductive layer are insulated from each other and are disposed on the second substrate, the conductive layer is disposed between the touch function layer and the first substrate; and

    the conductive layer is configured as a heating layer in a first state and is configured as a shield layer in a second state;

    a control device electrically connected to the conductive layer and the touch function layer respectively;

    a first temperature sensor provided outside the touch display device and a second temperature sensor provided inside the touch display device, the control device being electrically connected to the first temperature sensor and the second temperature sensor respectively;

    the first temperature sensor being configured to monitor an ambient temperature, and the second temperature sensor being configured to monitor a temperature of the touch display device;

    the control device being configured such that when the ambient temperature is lower than or equal to a first threshold and the temperature of the touch display device is lower than a second threshold, the control device controls the conductive layer to be applied with a voltage to heat the touch display device; and

    when the ambient temperature is higher than the first threshold, the control device controls the conductive layer to be grounded to shield the touch function layer from electromagnetic interference.
