In the present embodiment, along parallel to spaced between the deformation direction L list structures 210 of flexible screen 1.So set
Put, when the list structure 210 is deformed upon (such as bending) with flexible screen 1, the discontinuity position between list structure 210 can produce ratio
The larger deformation space along deformation direction L, during so as to further avoid buffer structure 2 from being deformed upon with flexible screen 1, its
It is internal to produce fold in the region of corresponding deformation region 11.
It should be noted that edge can also contact with each other parallel between the deformation direction L list structures 210 of flexible screen 1,
As shown in Figure 4.That is the side along its length of list structure 210 is bonded to each other, and so can equally make list structure 210
When being deformed upon with flexible screen 1, the discontinuity position between list structure 210 produces certain deformation space.
Preferably, in the present embodiment, spaced set between list structure 210.Be arranged such, can make buffer structure 2 with
When flexible screen 1 deforms upon, discontinuous portion 21 can produce the deformation space that is evenly distributed in deformation region 11, so as to avoid not connecting
Fold locally occurs for the discontinuous portion 21 caused by the continuous local deformation space of portion 21 is either large or small.
Preferably, the spacing range between adjacent list structure 210 is 1~5mm.The spacing range can make discontinuous portion
21 meet a variety of deformation degree requirements of deformation region 11, avoid the discontinuous portion 21 for being correspondingly arranged in deformation region 11 from producing
Raw fold.
In the present embodiment, the corresponding both ends end of at least two list structures 210 is connected to each other.I.e. all strips
Structure 210 is connected to each other positioned at one end of the same side, and the other end positioned at opposite side of all list structures 210 connects each other
Connect, be arranged such, can connect the discontinuous portion 21 of buffer structure 2 and form an entirety, be advantageous to more accelerate buffer structure 2
It is sticked to promptly on the back side of flexible screen 1.
Certainly, the corresponding end of all list structures 210 can also be not connected with, as shown in figure 5, in the buffer structure 2 that is sticked
When, as long as being sticked one by one to list structure 210.
Preferably, in the present embodiment, grown as shown in Fig. 2 the length of list structure 210 is flexible screen 1 along list structure 210
Spend the 4/5~9/10 of the size in direction.That is the length of list structure 210 is substantially equal to flexible screen 1 in the length side of list structure 210
Upward size, list structure 210 is so set to absorb and disperse the external impact force that flexible screen 1 is subject to well, and
And it can be discharged well with deformational stress caused by the deformation of flexible screen 1 (i.e. stretching and shrinkage stress), avoid buffer structure 2
Produce fold.
In the present embodiment, buffer structure 2 also includes continuous portion 22, and continuous portion 22 is correspondingly arranged in the non-deformation of flexible screen 1
Region 12；Continuous portion 22 is connected with each other with discontinuous portion 21.The setting in the continuous portion 22 of the non-deformation region 12 of flexible screen 1, can be very
The external impact force that non-deformation region 12 is subject to is absorbed and disperseed well.
Certainly, continuous portion 22 can also mutually disconnect with discontinuous portion 21, as shown in figure 5, this is to the continuous of buffer structure 2
The effect of portion 22 and discontinuous portion 21 is all without having an impact.
In the present embodiment, buffer structure 2 is foam, and foam uses polymethyl methacrylate, polyurethane or polyethylene material
Material.Because foam made of above-mentioned material can absorb and disperse the external impact force that flexible screen 1 is subject to well, so generally
It is used as the buffer structure 2 being sticked at the back side of flexible screen 1.But because foam has no cross directional stretch and contractility in itself, institute
To need for the foam being sticked in the deformation region 11 of flexible screen 1 to be arranged to the structure of discontinuous portion 21.Certainly, buffer structure 2
Other materials for having and absorbing and disperseing external impact force can be used.
In addition, in the present embodiment, as shown in figure 3, buffer structure 2 is located at the back side of flexible screen 1 by double faced adhesive tape.Slow
The side back to flexible screen 1 for rushing structure 2 is also sticked and has graphite flake 3 and copper foil tape 4 successively, and graphite flake 3 and copper foil tape 4 are right
It should be sticked in the non-deformation region 12 of flexible screen 1, to prevent flexible screen 1 in dough deformation, to graphite flake 3 and copper foil tape 4
Cause to damage.Graphite flake 3 and copper foil tape 4 can play a part of radiating, for being carried out during the display of flexible screen 1 to it
Radiating.
