Abstract: The present disclosure discloses a pressure sensing panel and a display device. A strain sensing unit includes a switching transistor, a first resistive pressure sensing electrode and a second resistive pressure sensing electrode. The first reference voltage line and the second reference voltage line have a potential difference when the switching transistor is switched on. When the pressure sensing panel is deformed, the resistances of the first resistive pressure sensing electrode and the second resistive pressure sensing electrode change due to deformation of the first resistive pressure sensing electrode and the second resistive pressure sensing electrode at corresponding positions, which leads to a change in voltage between the first resistive pressure sensing electrode and the second resistive pressure sensing electrode. Then voltage signals output through the signal reading line will change, and deformation of the pressure sensing panel can be obtained through analyzing the output voltage signal.
