Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described by corresponding accompanying drawing.Obviously, described embodiment is only the present invention one
Section Example rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing

Below in conjunction with accompanying drawing, describe the technical scheme that various embodiments of the present invention provide in detail.
The invention provides a kind of flexible display screen, for solving prior art is applied to the electricity of adhesive layer by regulation
Stream, it is achieved problem inefficient during regulation flexible display screen shape.The structural representation of this display screen is as it is shown in figure 1, concrete
Including:
Display module 101 and adjusting means, wherein, described adjusting means is used for regulating the shape 101 of described display module,
And described adjusting means includes flexible substrate 102 and magnetic nanoparticle 103, described magnetic nanoparticle 103 is distributed in
The upper and lower surface of described flexible substrate 102；By regulating between described flexible substrate 102 upper surface magnetic nanoparticle
Distance, and regulate the distance between described flexible substrate 102 lower surface magnetic nanoparticle, change described display module
The shape of 101.
Below in the present invention by the distance between regulation flexible substrate upper surface magnetic nanoparticle, and flexible liner
Distance between the magnetic nanoparticle of bottom surface, the principle changing flexible display screen shape is described in detail:
When user wants to allow flexible display screen bend to the direction of flexible substrate upper surface (as shown in Figure 1), regulation flexibility
Between distance between the magnetic nanoparticle of substrate top surface, and the magnetic nanoparticle of flexible substrate lower surface away from
From so that the distance between N pole and S pole between the magnetic nanoparticle of this flexible substrate upper surface, less than this flexible substrate
The distance between N pole and S pole between the magnetic nanoparticle of lower surface.
Specifically, as in figure 2 it is shown, by regulation flexible substrate 102 upper surface magnetic nanoparticle between N pole and S
Distance S1 between pole, less than distance S2 between the N pole between the magnetic nanoparticle of flexible substrate 102 lower surface and S pole,
Display module 101 is bent to the direction of flexible substrate 102 upper surface.
Force analysis is carried out, specifically as a example by the magnetic nanoparticle of flexible substrate 102 upper and lower surface high order end
As shown in Figure 3, it is assumed that in Fig. 3, the distance between the magnetic nanoparticle of flexible substrate 102 upper surface is equal, is positioned at flexibility
Distance between the magnetic nanoparticle of substrate 102 lower surface is the most equal.In the horizontal direction, table in flexible substrate 102 it is positioned at
The magnetic nanoparticle of face high order end is by adjacent magnetic nano-particle captivation F1 to the rightNS, in order to balance F1NS, flexible liner
The end 102, gives the active force f1 being positioned at the magnetic nanoparticle of flexible substrate 102 upper surface high order end to the left, and f1 and F1NSGreatly
Little identical, in opposite direction；In like manner, can obtain according to force analysis, be positioned at the magnetic Nano of flexible substrate 102 lower surface high order end
Grain, also by adjacent magnetic nano-particle 103 captivation F2 to the rightNS, and receive flexible substrate 102 active force to the left
F2, and f2 and F2NSSize is identical, in opposite direction.
According to Newton's third law, the high order end of flexible substrate 102 upper surface is by magnetic nanoparticle to the right
Counteracting force f1 ＇, the high order end of flexible substrate 102 lower surface by magnetic nanoparticle counteracting force f2 ＇ to the right (such as Fig. 4
Shown in), due to f1 ＇ and F1NSSize is identical, f2 ＇ and F2NSSize is identical, again because being positioned at the magnetic of flexible substrate 102 upper surface
The distance between N pole and S pole between property nano-particle, less than the N between the magnetic nanoparticle of flexible substrate 102 lower surface
Distance between pole and S pole, therefore F1NSMore than F2NS, then f1 ＇ is more than f2 ＇, and now, flexible substrate 102 high order end will be to flexibility
The direction bending of substrate 102 upper surface.
In like manner, flexible substrate 102 low order end is by being positioned at the magnetic nanoparticle of flexible substrate 102 low order end work to the left
Exert oneself, and the active force that flexible substrate 102 upper surface low order end is subject to is subject to also greater than the low order end of flexible substrate 102 lower surface
The active force arrived, so flexible substrate 102 low order end also will bend to the direction of flexible substrate 102 upper surface.
Captivation between magnetic nanoparticle on other position of flexible substrate 102 upper surface, is all higher than being positioned at soft
Captivation between magnetic nanoparticle on property other position of substrate 102 lower surface, therefore, the shape of flexible substrate 102 will be in
The state to the bending of the direction of flexible substrate 102 upper surface the most as shown in Figure 1.Due to display module 101 and flexible substrate 102
It is close to, and flexible substrate 102 can play the effect supporting display module 101, therefore, if being shaped as of flexible substrate 102
Bend to the direction of flexible substrate 102 upper surface, display module 101 active force upwards can be given so that display module 101 is soft
Property substrate 102 provide active force under, also will present to the direction of flexible substrate 102 upper surface bending state (such as Fig. 1 institute
Show)
It is above-mentioned when the magnetic nanoparticle of flexible substrate 102 upper and lower surface high order end is carried out force analysis,
Only analyze the adjacent magnetic nano-particle captivation to high order end magnetic nanoparticle, but in actual applications, other positions
On magnetic nanoparticle also high order end magnetic nanoparticle can be produced active force, but compared to adjacent magnetic nano-particle pair
The captivation of high order end magnetic nanoparticle, the active force that the magnetic nanoparticle on other positions produces is relatively small, therefore,
Ignore during above analysis.
When user wants to allow flexible display screen bend to the direction of flexible substrate lower surface (as shown in Figure 5), regulation flexibility
Between distance between the magnetic nanoparticle of substrate top surface, and the magnetic nanoparticle of flexible substrate lower surface away from
From so that the distance between N pole and S pole between the magnetic nanoparticle of this flexible substrate upper surface, more than this flexible substrate
The distance between N pole and S pole between the magnetic nanoparticle of lower surface.
Specifically, as shown in Figure 6, by the N pole between the magnetic nanoparticle of regulation flexible substrate 102 upper surface and S
Distance S between pole1, more than distance S between the N pole between the magnetic nanoparticle of flexible substrate 102 lower surface and S pole2,
Display module 101 is bent to the direction of flexible substrate 102 lower surface.
Equally, the magnetic nanoparticle being pointed to flexible substrate 102 upper and lower surface high order end carries out force analysis,
As it is shown in fig. 7, be positioned at the magnetic nanoparticle of flexible substrate 102 upper surface high order end, by adjacent magnetic nano-particle to
Right captivation F3NS, and by flexible substrate 102 active force f3 to the left, and f3 and F3NSSize is identical, in opposite direction；
In like manner, can obtain according to force analysis, be positioned at the magnetic nanoparticle of flexible substrate 102 lower surface high order end, also by adjacent magnetic
Property nano-particle captivation F4 to the rightNS, and receive flexible substrate 102 active force f4 to the left, and f4 and F4NSSize
Identical, in opposite direction.
According to Newton's third law, the high order end of flexible substrate 102 upper surface is by power f3 ＇ to the right, flexible liner
The high order end of the end 102 lower surface is by counteracting force f4 ＇ (as shown in Figure 8) to the right, due to f3 ＇ and F3NSSize is identical, f4 ＇
With F4NSSize is identical, again because between N pole and S pole between the magnetic nanoparticle 103 of flexible substrate 102 upper surface
Distance, more than the distance between the N pole between the magnetic nanoparticle of flexible substrate 102 lower surface and S pole, therefore F3NSLittle
In F4NS, then f3 ＇ is less than f4 ＇, and now, flexible substrate 102 high order end will bend to the direction of flexible substrate 102 lower surface.
In like manner, flexible substrate 102 low order end it is positioned at by being positioned at the magnetic nanoparticle of flexible substrate 102 low order end to the left
Active force, and the power that is subject to of the low order end of flexible substrate 102 upper surface is similarly less than the low order end of flexible substrate 102 lower surface
The power being subject to, so flexible substrate 102 low order end also will bend to the direction of flexible substrate 102 lower surface.
Captivation between magnetic nanoparticle on other position of flexible substrate 102 lower surface, is respectively less than positioned at soft
Captivation between magnetic nanoparticle on property other position of substrate 102 lower surface, therefore, the shape of flexible substrate 102 will be in
The state to the bending of the direction of flexible substrate 102 lower surface the most as shown in Figure 5.If flexible substrate 102 is in flexible liner
The direction bending of the end 102 lower surface, can give the active force that display module 101 is downward so that display module 101 is in flexible substrate
Under 102 active forces provided, also will present the state (as shown in Figure 5) to the bending of the direction of flexible substrate 102 lower surface.
In the display screen that the present invention provides, user can apply external force to flexible display screen, and direct furnishing oneself needs
Shape, such as, flexible display screen is directly bent to the shape that oneself needs by user, due in the flexible substrate that the present invention provides
Surface and lower surface are distributed magnetic nanoparticle, therefore, when the shape that display screen furnishing oneself is needed by user by external force
After, magnetic nanoparticle in flexible substrate relies on interaction force each other so that even if flexible display screen not against
In the case of external force, it is possible to maintain the shape that user needs.
Display module in flexible display screen, includes thin film transistor (TFT) (TFT), the flexible display screen that the present invention provides
In, thin film transistor (TFT) distributing position on flexible substrates can have a variety of, and in one embodiment, thin film transistor (TFT) is soft
Property substrate distributing position, corresponding with the distributing position of the magnetic nanoparticle of flexible substrate upper surface, as it is shown in figure 9, display
The thin film transistor (TFT) 1011 in module 101 distributing position in flexible substrate 102, with the magnetic Nano of flexible substrate upper surface
The distributing position of granule is corresponding；In another embodiment, thin film transistor (TFT) is at the distributing position of flexible substrate, with flexible liner
The distributing position of the magnetic nanoparticle of bottom surface is corresponding；In another embodiment, thin film transistor (TFT) is in flexible substrate
Distributing position, the most corresponding with the distributing position of the magnetic nanoparticle of flexible substrate upper and lower surface.
Above-mentioned thin film transistor (TFT) distribution scenario on flexible substrates, when flexible display screen occurs bending, soft owing to having
Property substrate top surface and/or the protection of magnetic nanoparticle of lower surface, it is to avoid during the bending of screen body, thin film transistor (TFT) is damaged,
Have impact on the display performance of flexible display screen.
In accompanying drawing of the present invention, the shape of the magnetic nanoparticle in display screen is all spheroid form, in actual applications,
The shape of magnetic nanoparticle can also is that cubic shaped, rectangular shape, cylindrical shape or triangular prism shape etc., this
In the shape of magnetic nanoparticle is not made concrete restriction.
And, in display screen N pole between the magnetic nanoparticle of flexible substrate upper and lower surface and S pole it
Between distance, as long as can realize regulation in the magnetic distance range of this magnetic nanoparticle, such as, radius is 500 to receive
Magnetic distance between the Magnetic Spherical nano-particle of rice is 1000 nanometers, the magnetic between two these Magnetic Spherical nano-particle
Property distance less than or equal to 1000 nanometer time, between this two Magnetic Sphericals nano-particle, just there is magnetic force, therefore, the present invention system
During standby display screen, the either distance between N pole and the S pole between the magnetic nanoparticle of flexible substrate upper surface, more than also
It is less than the distance between the N pole between the magnetic nanoparticle of flexible substrate lower surface and S pole, is required to adjacent two magnetic and receives
Distance between rice grain is in the magnetic distance range of this magnetic nanoparticle.
It addition, Fig. 4 and Fig. 7 is all that the distance between the magnetic nanoparticle on surface on flexible substrates is equal, Yi Jirou
When distance between the magnetic nanoparticle of property substrate lower surface is equal, the magnetic Nano to flexible substrate high order end
Granule carries out force analysis.But in actual application, between flexible substrate upper surface or the magnetic nanoparticle of lower surface away from
