Claim 16:
17. A flexible display device, comprising:
a rolling assembly; and
a flexible display module at least partially wound in the rolling assembly,
wherein the rolling assembly comprises a shaft and at least a shell layer coaxially arranged from an inside to an outside of the rolling assembly, the shaft and the at least a shell layer are coupled to each other and collectively allow for formation of a cross-sectional curve based on a characteristic of an Archimedes spiral, and the flexible display module comprises a first end fixedly connected to the shaft;
wherein the flexible display module is configured to drive the rolling assembly to rotate in a direction of releasing the flexible display module from a retracted state along with a process of expanding the flexible display module, enabling a linked state of the shell layer and the shaft to be released;
wherein the rolling assembly is configured to rotate in a direction of retracting the flexible display module along with a process of retracting the flexible display module, enabling the shell layer and the shaft to return to the linked state;
wherein the shell layer comprises an inner shell layer coupled to an outer surface of the shaft and an outer shell layer coupled to an outer surface of the inner shell layer;
wherein the flexible display module is separated from the outer shell layer and the inner shell layer successively, and the outer shell layer and the inner shell layer successively release the linked state with the shaft along with the process of expanding the flexible display module; and
wherein the flexible display module is successively attached to the outer shell layer and the inner shell layer, and the inner shell layer and the outer shell layer successively return to the linked state with the shaft along with the process of retracting the flexible display module.
