1. A touch display device, comprising:
a backlight module comprising a backlight iron frame; and
a liquid crystal touch display panel arranged on a light-emitting side of the backlight module;
wherein the liquid crystal touch display panel comprises:
a touch electrode; and
a compensation electrode arranged on a side of the touch electrode facing the backlight module;

wherein the compensation electrode and the backlight iron frame are electrically connected with a ground signal terminal; and the touch electrode and the compensation electrode constitute a capacitor, a product of a capacitance value of the capacitor and a resistance value of the compensation electrode is smaller than a pulse width of a touch signal applied on the touch electrode, and an order of magnitude of the product is smaller than an order of magnitude of the pulse width of the touch signal.
