The plurality of fixing strips 512 are arranged at intervals, so that a sliding groove 513 is formed between two adjacent fixing strips 512, and then, the extending direction of the sliding groove 513 is consistent with the telescopic direction of the flexible display panel 1.

The moving part 52 may include a barrier 521, a bottom plate 522, two side plates 523, and a plurality of slide bars 524.

However, the moving actuator 53 and the rotating actuator 35 are two different devices, and a certain error is inevitable. For example, when the movement amount of the moving driver 53 is smaller than that of the rotating driver 35 when the roll display device is unrolled, the flexible display panel 1 is caused to warp; on the contrary, when the moving amount of the moving actuator 53 is larger than the moving amount of the rotary actuator 35, a tensile force is generated in the flexible display panel 1, which is disadvantageous to the display of the flexible display panel 1 and shortens the life of the flexible display panel 1. When the roll display device rolls, when the moving amount of the moving driver 53 is smaller than that of the rotating driver 35, a stretching force is generated on the flexible display panel 1, which is not favorable for the display of the flexible display panel 1 and also shortens the service life of the flexible display panel 1; in contrast, when the moving amount of the moving driver 53 is larger than that of the rotating driver 35, the flexible display panel 1 is warped. In order to avoid the influence of errors on the flexible display panel 1, when the flexible display panel 1 is unfolded, the moving driver 53 can be controlled to be the main driver, and the rotating driver 35 is not powered and only follows; when the flexible display panel 1 is rolled up, the control takes the rotation driver 35 as a main driver, and the moving driver 53 is not powered and only follows.
