[0063] Example 1

[0064] Reference Appendix Figure 1 Appendix Figure 2 and attached Figure 3The electronic device provided in this embodiment includes a display screen 1 and a connecting component 2. The display screen 1 is deformable. The connecting component 2 is attached to the display screen 1 on the non-display side of the display screen 1. The connecting component 2 is deformable under a target driving force to form a support state. When the display screen 1 is in a target posture, the connecting component 2 forms the support state to support the display screen 1 so that the display side of the display screen 1 remains flat.

[0065] Understandably, in order to address the issue that flexible screens are prone to wrinkles on their surface due to stress limitations caused by their own layered structure and stress limitations during installation or movement with the device, which not only affects the display effect but also the aesthetic appearance of the device, the electronic device provided in this embodiment provides a deformable connecting component 2 on the non-display side of the display screen 1. When the display screen 1 is in the target posture, i.e., the flattening device or display state, the connecting component 2 can be in a supporting state to support the display screen 1, so that the display side of the display screen 1 remains flat, thereby improving the display effect and the aesthetics of the device when the display screen 1 is in the target posture, i.e., the flattening device or display state.

[0066] The electronic device provided in this embodiment may be, but is not limited to, a mobile phone, tablet computer, laptop computer, smart wearable device, etc.; it may be equipped with, but is not limited to, a rollable screen, foldable screen, retractable screen, etc. The following description of this embodiment will use a rollable screen laptop computer as an example for detailed explanation, while foldable screens and retractable screens will be described in brief. For example, refer to the attached document. Figure 1For a laptop computer with a rollable screen, it may include a system end (not shown in the figure) and a display end. The display end may include a first bracket 3 and a second bracket 4 that can slide and cooperate with each other. The first bracket 3 may be provided with spaced grooves or rails, and the second bracket 4 may be provided with spaced sliders or blocks to achieve sliding. The bottom end of the second bracket 4 is provided with a rollable structure. Corresponding to the cooperation with the display screen 1, the display screen 1 may include a non-deformable area 16 and a deformable area 15 connected in sequence in the length direction. The non-deformable area 16 is fixedly attached to the first bracket 3, specifically, it may be fixedly attached to the bracket structure between adjacent grooves or rails. The end of the deformable area 15 is fixed to the rollable structure. Thus, when the first bracket 3 slides away from the second bracket 4 relative to the second bracket 4, the deformable area 15 will be pulled out from the rollable structure and supported by the second bracket 4 to cooperate with the non-deformable area 16 to form a complete display area. That is, the sliding direction of the first bracket 3 and the second bracket 4 can correspond to the length direction of the display screen 1. Correspondingly, when the first bracket 3 slides towards the second bracket 4, the deformable area 15 can be rolled up on the scroll structure for storage, thereby reducing the display area until the first bracket 3 and the second bracket 4 overlap. In this device structure, the non-deformable area 16 is fixedly attached to the first bracket 3, and the position of the corresponding slide groove or slide rail is suspended. Therefore, when the non-deformable area 16 is assembled and attached to the first bracket 3, different stress distributions may occur between the adhesive area and the non-adhesive area. The deformable area 15 may also be pulled or rolled between the first bracket 3 and the scroll structure, and uneven stress distribution may occur due to the pulling and movement between multiple structural components. As a result, wrinkles may occur in both the non-deformable area 16 and the deformable area 15 of the display screen 1. For example, a foldable phone may include a first body and a second body that can rotate relative to each other. The display screen 1 may include a non-deformable area 16, a deformable area 15 and a non-deformable area 16 connected sequentially along the length direction. The non-deformable areas 16 at both ends are fixedly attached to the first body and the second body, respectively. The deformable area 15 corresponds to the rotational connection between the two bodies. The display screen 1 itself is a multi-layer structure. When it is formed and stacked, uneven stress may occur. When it is attached to the two bodies in a whole-surface manner, uneven stress distribution may occur further. During the process of the deformable area 15 being pulled or deformed by the two non-deformable areas 16, uneven stress distribution may also occur due to the pulling and movement between multiple structural components. As a result, both the non-deformable area 16 and the deformable area 15 of the display screen 1 may develop wrinkles.For example, in a smart wearable device with a retractable screen, the display screen 1 can be entirely composed of deformable areas 15. The display screen 1 itself is a multi-layered structure, and uneven stress may occur during its formation and stacking. Consequently, during deformation and stretching, uneven stress distribution may result due to pulling and deformation, potentially causing wrinkles throughout the display screen 1. Accordingly, this embodiment includes a connecting component 2, which supports at least the deformable areas 15. When the display screen 1 is in a flattened state, the connecting component 2 supports at least the deformable areas 15, maintaining the flatness of this area. Therefore, it is easy to understand that the target posture of the display screen 1 in this embodiment can be either an overall flattened state or an overall display state.

[0067] The connecting component 2 is deformable, or at least a portion thereof is deformable. The connecting component 2 can have a natural state and a supported state. In its natural state, the connecting component 2 can be, but is not limited to, flexible, and does not affect the deformation of the deformable area 15. In its supported state, it provides support to the display screen 1 and can be, but is not limited to, rigid, flat, or convex towards the display side. The connecting component 2, or a portion thereof, can deform from its natural state to its supported state under the action of electric driving force, thermal driving force, magnetic driving force, etc., and can return to its natural state after the driving force disappears. In this embodiment, the connecting component 2 can be provided only for the deformable area 15 of the display screen 1 to reduce the degree of wrinkling in the deformable area 15; in this embodiment, the connecting component 2 can also be provided for the entire display screen 1 to reduce the degree of wrinkling of the entire display screen 1 and improve the overall consistency of the display screen 1. In this embodiment, when the connecting component 2 is provided for the entire display screen 1, it can replace the original support plate structure (SUS, SteelUse Stainless) on the back of the display screen 1.

[0068] The electronic device provided in this application includes a connecting component 2 for the deformable display screen 1. The connecting component 2 can be configured to support the display screen 1 when it is in a flattened state, thereby preventing wrinkles from forming or appearing and improving the display effect and the aesthetic appearance of the product. This effectively solves the problem that flexible screens are prone to wrinkles on the surface due to the stress limitations of their own stacked structure and the stress limitations during the installation or movement of the device, which not only affects the display effect but also the aesthetic appearance of the device.

[0069] Further, see attached document. Figure 2 and attached Figure 3In the specific implementation of the electronic device provided in this embodiment, the connecting component 2 includes a first memory metal layer 21; the first memory metal layer 21 at least covers the deformable area 15 of the display screen 1, and the first memory metal layer 21 has an initial state and a supported state; wherein, when the first memory metal layer 21 is in the initial state, the first memory metal layer 21 can deform with the deformable area 15 of the display screen 1; when the display screen 1 is in a flattened state, the first memory metal layer 21 can be in the supported state under the target driving force so that at least the deformable area 15 of the display screen 1 remains flat.

[0070] It is understandable that, in order to enable the connecting component 2 or a portion thereof to form a supported state, the connecting component 2 in this embodiment can be configured to include a first shape memory metal layer 21. The first shape memory metal layer 21 can be, but is not limited to, a magnetic shape memory alloy, which is a smart material with magnetic field-driven shape memory. It can induce a martensitic phase transformation through external magnetic field control or temperature control, thereby achieving a reversible change in macroscopic shape. It can be, but is not limited to, Ni-Mn-Ga (Heusler alloy), Ni-Co-Mn-In alloy, etc. The initial state of the first shape memory metal layer 21 can be the aforementioned natural state. In this state, the first shape memory metal layer 21 maintains a certain degree of ductility and deformability, and can be bent or stretched along with the deformable area 15 of the display screen 1. Correspondingly, the supported state of the first shape memory metal layer 21 is that when subjected to magnetic force or temperature control, the advantageously oriented martensitic variants inside it grow, achieving macroscopic deformation. It can be in the form of a slight convexity towards the display screen 1, thereby providing at least the deformable area 15 with a supporting force towards the outside of the device, so as to maintain a flat and wrinkle-free display shape on the display side.

[0071] Further, see attached document. Figure 4 In this embodiment, the electronic device further includes a second memory metal layer 22 in the connection component 2. The second memory metal layer 22 is attached to the side of the first memory metal layer 21 away from the display screen 1, corresponding to the deformable area 15 of the display screen 1. The second metal layer 22 has a second initial state and a reverse support state. When the second memory metal layer 22 is in the second initial state, the second memory metal layer 22 can be in the support state along with the first memory metal layer 21. Under the second target driving force, the second memory metal layer 22 can be in the reverse support state so that the first memory metal layer 21 can be supported in the direction away from the display screen 1 along with the second memory metal layer 22, and the deformable area 15 of the display screen 1 can be deformed.

[0072] Specifically, to improve the deformability of the deformable region 15 of the display screen 1, or to reduce the difficulty of deformation, a second shape memory metal layer 22 is added at the position corresponding to the deformable region 15 in this embodiment. The second shape memory metal layer 22 can be the same magnetic shape memory alloy as the first shape memory metal layer 21. The difference is that the support direction of the second shape memory metal layer 22 is opposite to that of the first shape memory metal layer 21. This can be achieved by stacking two identical shape memory metal layers in opposite directions, and their thicknesses can be the same. The second initial state of the second shape memory metal layer 22 is the same as the initial state of the first shape memory metal layer 21, and it can maintain a certain degree of ductility and deformability. (Refer to the attached figure.) Figure 5 In this embodiment, when the first memory metal layer 21 is in a supported state, the second memory metal layer 22 can be controlled to be in a second initial state, thereby enabling the second memory metal layer 22 to be supported towards the display side along with the first memory metal layer 21; correspondingly, refer to the attached... Figure 6 The reverse support state of the second memory metal layer 22 is opposite to the support direction of the first memory metal layer 21. Therefore, when the display screen 1 needs to deform, the first memory metal layer 21 is controlled to be in its initial state. At this moment, the second memory metal layer 22 can be controlled to deform inwards, away from the display screen 1, providing greater redundancy for the deformation of the display screen 1 and reducing bending difficulty. It is easy to understand that in this embodiment, the first memory metal layer 21 and the second memory metal layer 22 can be controlled separately, for example, by setting corresponding magnetic control mechanisms. Alternatively, in this embodiment, the first memory metal layer 21 and the second memory metal layer 22 can be controlled separately by using the same magnetic control mechanism and changing the magnitude of the magnetic field force. For example, when the magnetic field force is small, it can drive the first memory metal layer 21; when the magnetic field force is large, it can drive the second memory metal layer 22. Correspondingly, the magnitude of the magnetic field force can be adjusted by the applied voltage and / or applied current.

[0073] Furthermore, for the case where only the first memory metal layer 21 is provided on the non-display side of the display screen 1, and the deformable area 15 and the non-deformable area 16 are both provided with the first memory metal layer 21, this embodiment can drive deformation in the following ways; and it should be noted that in this embodiment... Figures 7 to 13 The dashed line in the middle is the dividing line between deformable region 15 and non-deformable region 16.

[0074] The first method, see attached document. Figure 7 and attached Figure 8The connecting component 2 includes a first magnetic element 5 and a second magnetic element 6 with opposite magnetic properties; the first magnetic element 5 and the second magnetic element 6 are arranged opposite each other along any pair of opposite sides of the first memory metal layer 21, and the two can generate a magnetic field passing through the first memory metal layer 21; when the first magnetic element 5 and the second magnetic element 6 are energized, the magnetic force formed between them acts on the first memory metal layer 21, so that the first memory metal layer 21 is in the supported state; when the first magnetic element 5 and the second magnetic element 6 are de-energized, the magnetic force formed between them disappears, and the first memory metal layer 21 is in the initial state.

[0075] In this configuration, the first magnetic component 5 and the second magnetic component 6 can correspond to the N pole and S pole respectively, or they can be interchanged; the first magnetic component 5 and the second magnetic component 6 can be arranged relative to each other along the length of the device. Figure 8 It can also be set relative to the width of the device. Figure 7 Of course, the first magnetic element 5 and the second magnetic element 6 can be correspondingly disposed on the first support 3 and the second support 4, located between the support and the connecting assembly 2. Specifically, when the first magnetic element 5 and the second magnetic element 6 extend along the length direction of the first support 3, the first magnetic element 5 can be disposed at the top of the first support 3, and the second magnetic element 6 can be disposed at the bottom of the second support 4. When the first magnetic element 5 and the second magnetic element 6 extend along the width direction of the first support 3, the first magnetic element 5 can include two parts, the first part disposed on the left side frame of the first support 3, and the second part disposed on the left side frame of the second support 4. Similarly, the second magnetic element 6 can include the first part and the second part disposed on the right side frame of the first support 3 and the second support 4, respectively. Thus, when the first support 3 slides relative to the second support 4, the entire connecting assembly 2 can also be controlled, avoiding partial loss of control. When the first magnetic element 5 and the second magnetic element 6 are energized, the magnetic field is perpendicular or approximately perpendicular to the first memory metal layer 21, generating a magnetic force that causes it to become a supported state. In this configuration, the regulation of the first memory metal layer 21 can be controlled as a whole, either by controlling the deformable region 15 alone or by controlling both the deformable region 15 and the non-deformable region 16 simultaneously.

[0076] The second method is detailed in the appendix. Figure 11The first memory metal layer 21 corresponding to the non-deformable area 16 of the display screen 1 is attached to the bracket of the electronic device; the bracket includes a plurality of sub-brackets spaced apart along a first direction a; the first direction a and the direction of the non-deformable area 16 pointing to the deformable area 15 when the display screen 1 is in a flattened state satisfy the perpendicular condition; the first magnetic element 5 and the second magnetic element 6 are respectively arranged on both sides of the sub-brackets along the first direction a; when at least part of the first magnetic element 5 and the second magnetic element 6 are energized, the magnetic field force formed between them acts on the first memory metal layer 21 corresponding to them, so that part of the first memory metal layer 21 is in the supported state; when the first magnetic element 5 and the second magnetic element 6 are de-energized, the magnetic field force formed between them disappears, and the first memory metal layer 21 corresponding to them is in the initial state.

[0077] In this configuration, the first magnetic element 5 and the second magnetic element 6 can have the same magnetism as in the first configuration; the bracket can correspond to the aforementioned first bracket 3, and the sub-bracket can correspond to the aforementioned bracket structure between the slide groove or slide rail; the first direction a can correspond to the aforementioned equipment width direction. In this configuration, based on the first configuration, the first memory metal layer 21 of the non-deformable area 16 can be controlled individually and in zones. That is, a first magnetic element 5 and a second magnetic element 6 are respectively set on both sides of each sub-support or each slide or rail along the first direction a. They can be, but are not limited to, directly connected to the first support 3, thereby controlling at least the display screen in the suspended state. Multiple first magnetic elements 5 and second magnetic elements 6 can be powered on synchronously as a whole. For example, when the display screen 1 is in a flattened state or the non-deformable area 16 is in a display state alone, all the first magnetic elements 5 and second magnetic elements 6 can be powered on as a whole to control the first memory metal layer 21 in a supported state and eliminate wrinkles. Alternatively, targeted local power can be applied according to the wrinkle location. For example, after detecting the wrinkle location and degree by using an imaging luminance meter and a ring light source system or by using high-resolution microscopic imaging technology, the first magnetic element 5 and second magnetic element 6 at the corresponding location can be powered on to control the first memory metal layer 21 in a supported state and eliminate wrinkles. This setting improves the precision of control and further enhances the display effect.

[0078] The third method, see attached document. Figure 9The connecting component 2 includes a first magnetic pole group 7 and a second magnetic pole group 8; the first magnetic pole group 7 corresponds to the deformable region 15 of the display screen 1, and the first magnetic pole group 7 includes a third magnetic element 71 and a fourth magnetic element 72 spaced apart on both sides of the first memory metal layer 21 and having opposite magnetic properties; the second direction is perpendicular to the direction of the non-deformable region 16 pointing to the deformable region 15 when the display screen 1 is in a flattened state; the second magnetic pole group 8 corresponds to the non-deformable region 16 of the display screen 1, and the second magnetic pole group 8 includes a fifth magnetic element 81 and a sixth magnetic element 82 spaced apart on both sides of the first memory metal layer 21 and having opposite magnetic properties.

[0079] In this configuration, the second direction and the first direction a can be the same or opposite directions. The magnetism of the third magnetic element 71 and the fourth magnetic element 72 can correspond to the magnetism of the first magnetic element 5 and the second magnetic element 6, respectively. The same applies to the fifth magnetic element 81 and the sixth magnetic element 82, and the fifth magnetic element 81 and the third magnetic element 71 have the same magnetic poles, as do the sixth magnetic element 82 and the fourth magnetic element 72. The third magnetic element 71 and the fourth magnetic element 72 can be disposed on the first support 3, and the fifth magnetic element 81 and the sixth magnetic element 82 can be disposed on the second support 4. This configuration can be included in the first configuration. The control of the first memory metal layer 21 can be achieved by controlling the deformable region 15 alone, or by controlling the deformable region 15 and the non-deformable region 16 simultaneously or separately.

[0080] The fourth type, see attached document. Figure 10 The connecting component 2 includes a third magnetic pole group 9 and a fourth magnetic pole group 10; the third magnetic pole group 9 corresponds to the deformable area 15 of the display screen 1, and includes a seventh magnetic element 91 and an eighth magnetic element 92 spaced apart on both sides of the deformable area 15 along a third direction b and having opposite magnetic properties; the third direction b and the direction of the non-deformable area 16 pointing to the deformable area 15 when the display screen 1 is in a flattened state satisfy the parallel condition; the fourth magnetic pole group 10 corresponds to the non-deformable area 16 of the display screen 1, and includes a ninth magnetic element 101 and a tenth magnetic element 102 spaced apart on both sides of the non-deformable area 16 along the third direction b and having opposite magnetic properties.

[0081] In this configuration, the third direction b can be the length direction of the device, which can be perpendicular or approximately perpendicular to the first direction a and the second direction. The magnetic poles of the seventh magnetic element 91 and the eighth magnetic element 92 can correspond to the magnetic poles of the first magnetic element 5 and the second magnetic element 6, respectively. Similarly, the magnetic poles of the ninth magnetic element 101 and the tenth magnetic element 102 are the same, and the magnetic poles of the ninth magnetic element 101 and the seventh magnetic element 91 are identical. The seventh magnetic element 91 and the eighth magnetic element 92 can be respectively disposed at the upper and lower ends of the first support 3, and the ninth magnetic element 101 and the tenth magnetic element 102 can be disposed at the upper and lower ends of the second support 4. In this configuration, the control of the first memory metal layer 21 can be achieved by controlling the deformable region 15 alone, or by controlling the deformable region 15 and the non-deformable region 16 simultaneously or individually.

[0082] The fifth type, see attached document. Figure 12 The first magnetic element 5 and the second magnetic element 6 are spaced apart on both sides of the first memory metal layer 21 along a fourth direction. The fourth direction is parallel to the direction in which the non-deformable region 16 of the display screen 1 points to the deformable region 15 when the display screen 1 is in a flattened state. The connecting assembly 2 also includes a fifth magnetic pole group 11 and a sixth magnetic pole group 12. The fifth magnetic pole group 11 corresponds to the deformable region 15 of the display screen 1. The fifth magnetic pole group 11 includes an eleventh magnetic element 111 and a twelfth magnetic element 112, which are spaced apart on both sides of the deformable region 15 along a fifth direction and have the same magnetic properties. The fifth direction is parallel to the direction in which the non-deformable region 16 of the display screen 1 is in a flattened state. The direction pointing to the deformable region 15 satisfies the perpendicular condition; the sixth magnetic pole group 12 corresponds to the non-deformable region 16 of the display screen 1, and the sixth magnetic pole group 12 includes a thirteenth magnetic element 121 and a fourteenth magnetic element 122 that are spaced apart on both sides of the non-deformable region 16 along the fifth direction and have the same magnetism; wherein, the magnetism of the fifth magnetic pole group 11 is opposite to the magnetism of the first magnetic element 5, and the end of the fifth magnetic pole group 11 that is away from the sixth magnetic pole group 12 is connected to the second magnetic element 6; the magnetism of the sixth magnetic pole group 12 is opposite to the magnetism of the second magnetic element 6, and the end of the sixth magnetic pole group 12 that is away from the fifth magnetic pole group 11 is connected to the first magnetic element 5.

[0083] In this configuration, the fourth direction can be the same as or opposite to the third direction b, and the fifth direction can be the same as or opposite to the first direction a. In this configuration, the first magnetic element 5 and the second magnetic element 6 can be respectively disposed on the upper part of the first bracket 3 and the lower part of the second bracket 4. The fifth magnetic pole group 11 can be disposed on both sides of the first bracket 3, and the sixth magnetic pole group 12 can be disposed on both sides of the second bracket 4. The fifth magnetic pole group 11 and the first magnetic element 5 are attracted by opposite poles, and the sixth magnetic pole group 12 and the second magnetic element 6 are attracted by opposite poles. This allows magnetic fields to be generated at the corners of the first bracket 3 and the second bracket 4 to adjust and support the corners of the display screen 1, improving the overall support of the display screen 1 when the first memory metal layer 21 is in a supported state, thus improving both the support effect and the display effect.

[0084] Further, see Appendix Figure 13 In this embodiment, the electronic device includes a first magnetic control component 13 and a second magnetic control component 14. The first magnetic control component 13 and the second magnetic control component 14 are disposed on both sides of the second memory metal layer 22 along a sixth direction. The sixth direction is perpendicular to the direction from the non-deformable area 16 to the deformable area 15 when the display screen is flattened. The first magnetic control component 13 includes a fifteenth magnetic element 131, a magnetoresistive layer 132, and a sixteenth magnetic element 133 stacked along a seventh direction c. The fifteenth magnetic element 131 and the sixteenth magnetic element 133 have different magnetic properties. The seventh direction c is the stacking direction of the first memory metal layer 21 and the second memory metal layer 22. The second magnetic control component 14 includes the sixteenth magnetic element 133, the magnetoresistive layer 132, and the fifteenth magnetic element 131 stacked along the seventh direction c. The first magnetic control component 13 and the second magnetic control component 14 correspond to the middle of the first memory metal layer 21 and the second memory metal layer 22 in the seventh direction c.

[0085] It is understandable that, corresponding to the form in which a second memory metal layer 22 is simultaneously disposed on the back of the first memory metal layer 21, in this embodiment, the first memory metal layer 21 and the second memory metal layer 22 of the deformable region 15 can be individually controlled, that is, a first magnetocontrol group 13 and a second magnetocontrol group 14 can be disposed. In this disposal method, the sixth direction can be the same as or opposite to the first direction a, and the seventh direction c can be a direction that is perpendicular or approximately perpendicular to both the first direction a and the third direction b. The seventh direction c can be the thickness direction of the display screen 1. In this disposal method, the first magnetocontrol group 13 and the second magnetocontrol group 14 are disposed corresponding to the deformable region 15. The disposal method of the non-deformable region 16 can be referred to the foregoing description and will not be repeated here. In this configuration, the first magnetic control group 13 and the second magnetic control group 14 are not connected to the first bracket 3 or the second bracket 4. An additional mounting frame can be provided. The mounting frame is placed on the outer sides of the display screen 1 and corresponds to the middle of the sum of the thicknesses of the first memory metal layer 21 and the second memory metal layer 22. This allows the fifteenth magnetic element 131 and the sixteenth magnetic element 133 to correspond to the first memory metal layer 21 and the second memory metal layer 22, respectively. The magnetism of the fifteenth magnetic element 131 and the sixteenth magnetic element 133 can be the same. In this embodiment, a magnetoresistive layer 132 is used to block the two elements, preventing the other from being affected when either the fifteenth magnetic element 131 or the sixteenth magnetic element 133 is energized. In this embodiment, when the first memory metal layer 21 is energized and becomes a support state, the second memory metal layer 22 needs to be in a second initial state. When the second memory metal layer 22 is in a second support state, the first memory metal layer 21 needs to be in an initial state. It is obvious that the magnetoresistive layer 132 can be, but is not limited to, a non-magnetic metal material, such as copper, aluminum, etc. The second magnetic control group 14 is configured in the opposite way to the first magnetic control group 13. The relevant principles are detailed in the preceding description and will not be repeated here. This configuration allows for independent control of the second memory metal layer 22 and the first memory metal layer 21 by individually energizing the magnetic components within different magnetic control groups. This improves efficiency and accuracy, prevents mutual interference between the two memory metal layers, and enhances display and wrinkle-reducing effects.

[0086] Furthermore, in the specific implementation of the electronic device provided in this embodiment, the first memory metal layer 21 covers the non-deformable area 16 of the display screen 1, and the first memory metal layer 21 can deform in response to the target temperature to form a support state; wherein, the first memory metal layer 21 in the support state can be connected to the bracket of the electronic device along with the display screen 1.

[0087] Understandably, this setup utilizes the property of the first memory metal layer 21 to deform under temperature. After bonding the first memory metal layer 21, located in the non-deformable region 16, to the first bracket 3 and the non-deformable region 16 of the display screen 1, heating is used to keep the first memory metal layer 21 in a supported state and maintain that state. This eliminates uneven stress distribution caused by bonding, preventing wrinkles during subsequent use, making it efficient and convenient. It is also easy to understand that with this setup, the first memory metal layer 21, after being deformed by high temperature during subsequent use, will not revert to its initial state and will always maintain a supported state. Correspondingly, the control methods for the first memory metal layer 21 in the deformable region 15 and the combination of the first memory metal layer 21 and the second memory metal layer 22 can be referred to the above content and will not be elaborated here.

[0088] It should be noted that the setup principle is the same for foldable and retractable screens, so it will not be elaborated on here.
