1. A flexible display panel comprising:
a display layer;
an upper layer group located above the display layer, wherein the upper layer group comprises at least one layer; and
a lower layer group located below the display layer, wherein the lower layer group comprises at least one layer, the at least one layer of at least one of the upper layer group and the at least one layer of the lower layer group comprises at least one target layer; and
in response to a trigger condition, a characteristic parameter of at least partial region of the at least one target layer in at least one of the upper layer group and the lower layer group switches between a first range and a second range, and a minimum value in the second range is greater than a maximum value in the first range, wherein the trigger condition comprises a condition that a temperature of the at least partial region is higher than a third threshold or lower than a fourth threshold, wherein the fourth threshold is less than the third threshold;
a temperature adjustment device, wherein the trigger condition is provided by the temperature adjustment device; the temperature adjustment device further comprises a heating element configured to heat the at least partial region of the at least one target layer; the flexible display panel is configured to bend along an axis during a sliding process, the heating element is disposed in a target region on a first side of the axis, and the heating element is configured for heating the at least partial region of the at least one target layer that has reached the target region; the flexible display panel includes a non-bending portion and a bending portion, part or all of the bending portion is bent around the axis; the heating element is arranged corresponding to the non-bending portion.
