Abstract
A touch display device includes 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; the liquid crystal touch display panel includes a touch electrode (); and a compensation electrode (R) arranged on a side of the touch electrode facing the backlight module. 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 (C), 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.
