Connection, elastic adhesive tape connection and the attracting connection of magnetic.The elastic connection at the both ends of support 31 is on the one hand in ring support 30
Tangential force along the circumferential direction, the approximate annulus that correction ring support 30 is formed are produced during radial outward movement to support 31；
On the other hand, tangential force along the circumferential direction is produced during 30 radial inward movement of ring support to support 31, annular branch can be made
Frame 30 returns to original state, will not produce serious deformation.
It will be understood to those skilled in the art that the ring support 30 include 3 supports 31 or more support and
The support casing 32 of respective amount, i.e. support 31 are identical with the quantity of support casing 32.The axle tail 53 of connecting shaft 50 described in the present embodiment
It is connected with the approximately mid way between of support 31, in actual drawing process, such as when outwards doing radial direction telemechanical, due in support 31
Between be pulled outwardly and stretch, and the inner side of support 31 is flexibly connected with plastic deformation plate 90, so by inside tensile force, the ring
Shape support 30 is local to form the approximate circle stretch ring that concaves, and this stretch ring is more slightly smaller than the ring of same radius, the branch
Area that the end positions of frame 31 locally move inward but its stretching comes is far longer than the ring that ring support 30 before stretching forms
Area.The present embodiment is applied to support 31 when that drawing process bears the reaction force of plastic deformation plate 90 is larger.
Another optional embodiment, the axle tail 53 of the connecting shaft 50 is connected with the position of support casing 32, in actual stretching
During, for example when outwards doing radial direction telemechanical, drive the both ends of support 31 to stretch out because support casing 32 is pulled outwardly to stretch, and prop up
The inner side of frame 31 is flexibly connected with plastic deformation plate 90, so by inside tensile force, the ring support 30 can be formed closely
Like the stretch ring of circle.This stretch ring is more slightly smaller than the ring of same radius, and the centre position of the support 31 locally moves inward,
But its stretch come area be far longer than stretching before ring support 30 form ring area.Simultaneously because adjacent support 31 it
Between elastic connection, the local situation about concave of the ring support 30 can be mitigated, make the ring of softened state and original state
It is approximately complete circular ring type that shape support 30, which is formed,.The present embodiment is applied to support 31 when drawing process bears plastic deformation plate 90
When reaction force is smaller.
The drive mechanism 70 includes drive rod 71 and the (not shown) of motor 72, motor 72 pass through reduction gearing
73 (not shown) are engaged with drive rod 71.The rotation of motor 72 drives drive rod 71 to rotate, and driving rotating disk 60 rotates and then band
Dynamic connecting shaft 50 does radial motion.
As Figure 4-8, by original state to softened state in deformation process：The motor 72 of the drive mechanism 70
It is engaged by the (not shown) of reduction gearing 73 with drive rod 71.Motor 72 turn clockwise (Fig. 6 visual angles) drive drive rod
71 rotations, driving rotating disk 60 rotate and then drive connecting shaft 50 to do radial motion, and the spindle nose 51 of connecting shaft 50 is along the of rotating disk 60
One chute near-end 612 moves to the second chute distal end 611, can only be moved radially because connecting shaft 50 is defined, so connection
The axle tail 53 of axle 50 drives the ring support 30 to be moved radially outward.Ring support 30 drives the plastic deformation plate 90 outside
Radially strut, and strut the outward radial of flexible panel substrate 12, finally realize that flexible display screen 10 is radially realized
Softened state.It will be understood to those skilled in the art that by softened state to original state to Aforesaid deformation process just phase
Instead, simultaneously because being elastic connection between the inner support 31 of the ring support 30, during original state is returned to, elasticity is even
The support 31 connect produces tangential force along the circumferential direction in 30 radial inward movement of ring support to support 31, is advantageous to make ring
Shape support 30 returns to original state, will not produce serious deformation.
