Display module

A display module, comprising:

• a flexible panel, wherein bumps are formed along two opposing sides of the flexible panel respectively, and a size of the bumps in a thickness direction of the flexible panel is larger than a thickness of the flexible panel;
• two curled slide rails arranged opposite to and in parallel with each other, wherein each of the two curled slide rails has a groove that extends along a curling direction of the slide rail for receiving a respective bump of the bumps, and for each groove, a groove entry for entering the groove is formed at one end of a respective slide rail of the two curled slide rails, wherein the two curled slide rails and a space therebetween form a receiving rail for receiving the flexible panel;
• wherein each of the bumps is able to enter a respective groove of a respective slide rail of the two curled slide rails through the groove entry of the groove and move along the groove where the bump resides, so as to drive the flexible panel to be curled and received within the receiving rail and drive the flexible panel to be pulled out from the receiving rail, and wherein each of the two curled slide rails is at least partially stacked and is stacked in layers at stacking positions, and there is a spacing between adjacent layers.
