Alternatively, the width of the first sub-rail 111 in the first direction may be greater than the width of the second sub-rail 112 in the first direction, so that the first sub-rail 111 matches with the first support shaft 211 and the second sub-rail 112 matches with the second support shaft 212.
The radii and the arrangement of the first support shaft 211 and the second support shaft 212 are not limited to these. For example, the first support shaft 211 may be disposed on the back side of the flexible display module 20, and the second support shaft 212 may be disposed on the display surface side of the flexible display module 20. In other alternative implementations, the radius of the first support shaft 211 may be equal to or greater than the radius of the second support shaft 212, and is also within the scope of the present application.
