     DETAILED DESCRIPTION OF EMBODIMENTS 
     The present invention provides a flexible display screen and TV set thereof, in order to make the purpose, technical solution and the advantages of the present invention clearer and more explicit, further detailed descriptions of the present invention are stated here, referencing to the attached drawings and some Preferably embodiments of the present invention. It should be understood that the detailed embodiments of the invention described here are used to explain the present invention only, instead of limiting the present invention. 
     Referencing to  FIG. 1  and  FIG. 2 , wherein,  FIG. 1  illustrates a structural diagram of a flexible display screen as provided in the present invention.  FIG. 2  illustrates a decomposition diagram of the flexible display screen as provided in the present invention. The present invention provides a flexible display screen, comprising a screen  10  and an arc tube  20  applied to switching the screen  10  between a curved shape and a flat shape; a plurality of spacing sockets  30  are arranged on a back of the screen  10 , a plurality of spacing holes  301  are arranged in the spacing sockets  30 , each of the arc tube  20  is closely matching the spacing hole  301  and rotatable around the spacing hole  301  under an action of an external force; the arc tube  20  has an arc shaped surface  21 , when the arc shaped surface  21  of the arc tube  20  faces toward a vertical direction, the screen  10  is in a flat shape, while the arc shaped surface  21  of the arc tube  20  faces toward a horizontal direction, the screen  10  becomes a curved shape. 
     Wherein, the present invention flexibly adjusts a bending curvature of the screen  10  through the arc tube  20 , making the display screen switch freely between the curved shape and the flat shape, giving a viewer a best angle of view, satisfying a different requirement of the viewer, giving a better experience, and being more practical and humanized, matching a market requirement better, while it owns a simple structure and a convenient application; which has effectively solved a problem in the prior art, that a display screen may only be either a flat shape or a curved shape, and making a user not be able to switch in between as requirement. 
     Preferably, the display screen further comprises a driving device, applied to driving the arc tube  20  to rotate, the driving device drives the arc tube  20  to rotate through a worm-gear transmission pair. As shown in  FIG. 4 , the worm-gear transmission pair includes a worm gear  51  set in the arc tube  20  and a worm  52  set in a mounting seat  60 , which is fixedly arranged on a back of the screen  10 , the worm gear  51  and the worm  52  are intermeshing, the driving device connects to the worm  52  and drives the worm  52  to rotate. Since the worm-gear transmission pair has an auto-lock function, when the driving device stops driving, the screen  10  may keep its state. A transmission through a worm-gear transmission pair, may make the bending curvature of the screen  10  be adjusted freely, which may be adjusted to a best visual state as required, when the viewer is watching the display screen, which is more humanized. 
     It should be noted that, a transmission mode of the driving device is not limited thereto, in other preferable embodiments of the present invention, the driving device may transmit through a gear transmission pair or a gear and rack transmission pair. When the driving device is driving through the gear transmission pair, a first gear may be sleeved on the arc tube  20 , and a second gear intermeshes the first gear, when driving the second gear to rotate, the first gear is also driven to rotate, and making the arc tube  20  rotate. When the driving device is driving through the gear and rack transmission pair, a gear may be sleeved on the arc tube  20 , while the rack intermeshes and connects to the gear, through driving the rack to move linearly, driving the gear to rotate, and making the are tube  20  rotate. 
     Preferably, the driving device is a manual driving device, including a rotatable plate  41 , by which, a more effective result may be achieved, the rotatable plate  41  includes a rotation axis  411  which connects to the worm  52  and drives the worm  52  to rotate. Specifically, a through-hole  601  is arranged in the mounting seat  60 , the rotation axis  411  penetrates through the through-hole  601  and connects with the worm  52 . Preferably, in order to facilitate a manual driving, a handle  412  is further arranged on the rotation plate  41 , through rotating the handle  412 , making the rotation plate  41  rotate, so as to driving the arc tube  20  rotate through the worm-gear transmission pair, before achieving a goal of adjusting the bending curvature of the screen  10 . 
     It should be noted that the driving mode of the driving device is not limited thereto, in other preferable embodiments of the present invention, the driving device may also be a motor, whose an output shaft connects to the worm  52  and drives the worm  52  rotate. Through a rotation of the motor, drives the worm  52  rotate, so as to make the worm gear  51  rotate, and finally achieve the rotation of the arc tube  20 , and achieve the goal of adjusting the bending curvature of the screen  10 . 
     Preferably, the mounting seat  60  is arranged in the middle of the screen  10 , a plurality of the spacing sockets  30  are arranged on both sides of the mounting seat  60  symmetrically, so as to keep the bending curvature a same in every position of the screen  10 . In the present embodiment, there are four spacing sockets  30 , which are distributed symmetrically on both sides of the mounting seat  60 . It should be noted that, a number of the spacing sockets  30  may be decided according to a size of the screen  10 , in other preferable embodiments of the present invention, the number of the spacing sockets  30  may be six, eight or more. 
     Preferably, the mounting seat  10  has a rotating hole  602 , the arc tube  20  penetrates through the rotating hole  602 . 
     Preferably, the screen  10  is a flexible screen, so as to make the screen  10  change following a change of the arc tube  20 . The arc tube  20  is a steel arc tube, owning a good strength of structure. 
     Preferably, shown as  FIG. 3 , the spacing hole  301  is a kidney shaped hole, a horizontal width of the spacing hole  301  is matching a diameter of the arc tube  20 , a vertical width of the spacing hole  301  is larger than the diameter of the arc tube  20 , so as to make the horizontal width of the spacing hole  301  satisfy a horizontal direction movement when the arc tube  20  is changing, and meanwhile, make the screen  10  generate a deformation through the spacing socket  30 , when the arc tube  20  is changing. 
     A process of use of the present invention is as follows: 
     When it is needed to adjust the screen  10  of the display screen into a flat shape, first, through rotating the handle  412  manually, driving the rotation plate  41  to rotate, then through the transmission by the worm-gear pair, driving the arc tube rotate; when the arc shaped surface  21  of the arc tube  20  faces toward a vertical direction, stop driving, and finally make the screen  10  keep a straight flat state (as shown in  FIG. 5  and  FIG. 6 ). 
     When it is needed to adjust the screen  10  of the display screen into a curved shape, the handle  412  may be rotated manually in a reverse direction, through the transmission by the worm-gear pair, the arc tube  20  is driven to rotate reversely, so as to make the screen  10  transit from the straight shape to the curved shape, and when the arc shaped surface  21  of the arc tube  20  is turning to the horizontal direction, the screen  10  owns the maximum bending curvature. (shown as  FIG. 7  and  FIG. 8 ). 
     The present invention further provides a TV set, the TV set includes a flexible display screen, whose specific structure may be referencing to the embodiments on the flexible display screen in the present invention and a plurality of descriptions from  FIG. 1  to  FIG. 8 , no more descriptions are repeated hereof.
