A display panel, an operation control method thereof and a display device for improving users' experience of display products. Wherein the display panel comprises a flexible substrate (1) and a sensor control circuit (3) and a sensitive element (4) provided on the flexible substrate (1), the sensor control circuit (3) is connected to the sensitive element (4), and a sensitive parameter of the sensitive element (4) varies with the bending degree of the flexible substrate (1) so that a detected signal passing through the sensitive element (4) varies with the bending degree of the flexible substrate (1); the sensor control circuit (3) includes a signal generating circuit for inputting the detected signal into the sensitive element (4), and a feedback circuit for converting the detected signal passing through the sensitive element (4) into a feedback signal indicating the bending degree of the flexible substrate (1) and for sending it to a control system connected to the display panel, so that the control system performs corresponding control operations in accordance with the feedback signal.
