Display panel and display device

A display device, comprising a display panel and a control module, wherein the display panel comprises:

• a thin film transistor arranged in a display area of the display panel, the thin film transistor comprising an active layer;
• a metal layer;
• a plurality of force sensors disposed in a same layer as one of the active layer and the metal layer, each of the plurality of force sensors comprising a first bridge arm, a second bridge arm, a third bridge arm, and a fourth bridge arm connected end-to-end in sequence;
• and
• a plurality of regulation resistors, each corresponding to a respective one of the plurality of force sensors, each of the plurality of regulation resistors comprises a first end connected to a voltage regulation end and a second end connected to a regulation bridge arm of the respective force sensor, wherein each regulation bridge arm is any one of the first bridge arm, the second bridge arm, the third bridge arm, and the fourth bridge arm of the respective force sensor,
• the control module is configured to, during a zero-setting mode, adjust a voltage value Ua at the voltage regulation end within a preset range, and acquire an output voltage difference Uo between two output ends of the force sensor;
• when Uo reaches a preset condition, the zero-setting mode terminates, take Ua at this moment as a replacement voltage value Uc, and take Uc as the voltage value at the voltage regulation end.
