Abstract: A display panel, a pressure sensitive touch screen, and a display device are disclosed. Pressure sensitive touch structures are arranged between an array substrate and a counter substrate. Each pressure sensitive touch structure includes a first touch electrode, a piezoelectric conversion layer, and a second touch electrode. In case each pressure sensitive touch structure is subject to a pressure, the pressure sensing unit determines the magnitude of pressure at the touch position by sensing a variation in the magnitude of voltage between the first touch electrode and the second touch electrode, thus realizing pressure touching. Since the pressure sensitive touch structures are embedded in the display panel, it is only required to make minor modification to the structural design of the display panel without being limited by the assembly tolerance. The detection accuracy is improved.
