Detailed description of the invention
It is further described below in conjunction with drawings and Examples.
Fig. 1 is the case of bending figure of the flexible display screen of first embodiment.This flexible display screen 10 includes flexible screen body 100 and the supporter 200 that stacking is arranged.Wherein supporter 200 is adjustable with the laminating of the back side of described flexible screen body and hardness.Supporter 200 hardness flexible or folding time, flexible display screen 10 can realize bending as shown in Figure 1.And when supporter 200 hardness be adjusted to can holding state time, then described flexible display screen 10 is fixed as the form of supporter, this form be described flexible display screen 10 through once or twice folding as above after formed V-arrangement, other 3D shapes such as Z-shaped, S shape, the 3D shape at this not doubling poststack too much repeats.
Flexible screen body 100 is to adopt flexible material making, flexible or folding display screen structure.
Supporter 200 includes magnetic control deformation layer and magnet unit.Magnetic control deformation layer is covered in the back side of flexible screen body 100, and the material or alloy by magnetic field control its own shape change is made.Concrete, owing to material itself has certain directivity, material deformation ability is correlated with magnetic density (direction), therefore when the material with thermoelasticity or stress-induced martensitic phase transformation is in martensitic state, after it is carried out the deformation of certain limit, by regulating external magnetic field density (direction), material can be completely recovered to the shape before deformation and volume.Owing to flexible display screen 10 is provided with the regulon being connected and can regulating magnetic field with described magnet unit, therefore regulon be can pass through and variation of magnetic force or the magnetic direction of magnet unit regulated, and then regulate the power of magnetic force on the controlled magnetic control direction of magnetic control shape-changing material, reach to regulate the purpose of the hardness of magnetic control deformation layer.

In the step of the deformation control method of the flexible display screen shown in Fig. 2, the line direction of the two of described magnet unit magnetic poles is rotated towards the direction vertical with controlled direction, described magnetic field, namely, the angle between the controlled direction of line and described magnetic field of two magnetic poles of described magnet unit is made to become greatly/diminish, and described angle is acute angle, the magnetic field on the controlled direction, magnetic field of magnetic control deformation layer can be made to reduce/increase.
In like manner, in the step of deformation control method, the line direction of the two of described magnet unit magnetic poles is rotated towards the direction parallel with controlled direction, described magnetic field, namely, the angle between the controlled direction of line and described magnetic field of two magnetic poles of described magnet unit is made to diminish/become big, and described angle is acute angle, the magnetic field on the controlled direction, magnetic field of magnetic control deformation layer can be made to increase/reduce.
In the second embodiment shown in Fig. 4, supporter 200 includes magnetic control deformation layer 210 ' and the electric magnet 220 ' as magnet unit.Electric magnet 220 ' includes flexible coil, and described regulon is the current regulating circuit (not shown) electrically connected with described flexible coil, for regulating the size of current of flexible coil.When size of current changes, corresponding magnetic field size also changes, thus respective change also occurs the hardness of magnetic control deformation layer 210 '.Flexible coil can also intert Flexible wick, to strengthen magnetic field intensity under same current condition.
Specifically, in the step of the deformation control method of the flexible display screen shown in Fig. 4, reduce/increase the electric current by described flexible coil, the magnetic field on the controlled direction, magnetic field of magnetic control deformation layer can be made to reduce/increase.
In like manner, in the step of deformation control method, increase/reduce the electric current by described flexible coil, the magnetic field on the controlled direction, magnetic field of magnetic control deformation layer can be made to increase/reduce.
In the present embodiment, after the energising of described flexible coil, the direction of magnetic pole is consistent with described controlled magnetic control direction.Refer to Fig. 5, the controlled magnetic control direction of magnetic control deformation layer 210 ' is as shown by arrows from bottom to top.Direction keeps consistent, it is possible to maximal efficiency utilizes magnetic field.
After being appreciated that flexible coil energising, the direction of magnetic pole can also be inconsistent with described controlled magnetic control direction.Further, in the step of the deformation control method of the flexible display screen shown in Fig. 4, it is also possible to the magnetic direction of pivoting flexible coil regulates the hardness of magnetic control deformation layer.Particularly as follows:
