1. A display device, comprising:

  • an array substrate and an opposing substrate arranged opposite to each other,a touch electrode pattern provided between the array substrate and the opposing substrate,a backlight module provided below the array substrate; and

    a counter electrode provided on the backlight module, the counter electrode and the touch electrode pattern forming a capacitive structure;

    wherein, in a touch detection period, a touch detection signal is loaded onto the touch electrode pattern and the counter electrode at the same time, to determine a touch position by detecting a change in a capacitance value of the respective touch electrode pattern;

    in a pressure detection period, a touch detection signal is loaded onto the touch electrode pattern or the counter electrode, to determine a magnitude of pressure in the touch position by detecting a change in a capacitance value between the touch electrode pattern and the counter electrode.
