The first base 10 is provided with a first reel 11 which is rotatably arranged, and the first reel 11 is used for winding or unfolding the flexible display screen 1;

The second base 20 is arranged relative to the second base 20, and is in a state of moving closer to or away from the first base 10 as the flexible display screen 1 is rolled up or unfolded;

The support assembly 30 includes a plurality of support plates 31 which are rotationally connected end to end, and the two outermost support plates 31 are respectively rotationally connected to the first base 10 and the second base 20, each The rotation axes of the support plate 31 are all parallel to the first scroll shaft 11;

The plurality of support plates 31 are in a superimposed or flush state as the second base 20 moves closer to or away from the first base 10 , and the plurality of support plates 31 in a flush state are paired The unfolded flexible display screen 1 is supported.

It can be understood that the flexible screen support structure 100 is applied to a mobile terminal, and the flexible display screen 1 presents a contracted or expanded state as the first base 10 and the second base 20 move closer or farther away from each other. After the flexible display screen 1 is unfolded, it can be fixed on a plurality of the supporting boards 31 . The mobile terminal may be a mobile phone, a tablet computer, or a notebook computer.

The first base 10 is provided with a first reel 11 , and the flexible display screen 1 is rolled by the first reel 11 , so that the flexible display screen 1 can be in a rolled contraction state. And when the first reel 11 unfolds the flexible display screen 1, the second base 20 is relatively far away from the first base 10, so that the plurality of support plates 31 are in a state of being flush with each other. The plurality of support plates 31 in a level state support the flexible display screen 1 , that is, the flexible display screen 1 is supported after being unfolded. The flexible screen supporting structure 100 can support the flexible display screen 1 when the flexible display screen 1 is unfolded, and facilitate the flexible display screen 1 to be tightly wound and contracted together when the flexible display screen 1 is rolled up, thereby improving user experience.
