DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It will be appreciated that the described embodiments are some rather than all of the embodiments of the present disclosure. Other embodiments obtained by those having ordinary skills in the art on the basis of the described embodiments without inventive efforts should fall within the scope of the present disclosure. In addition, under circumstances of no conflict, the embodiments and the features in the embodiments may be combined with each other.

In the following description, many details are explained in order to fully comprehend the present disclosure. However, the present disclosure can also be implemented in other ways different from those described herein. Those skilled in the art may do so without departing from the scope of the present disclosure. Therefore, the present disclosure is not limited by the embodiments described below.

As described in the background section, during the operation of the existing electronic devices, the bendable region often has the high failure rate and the reliability of the electronic devices with the bendable display screen needs to be improved.

As such, the present disclosure provides an electronic device.FIG.1is a structural diagram illustrating an exemplary electronic device according to some embodiments of the present disclosure. As shown inFIG.1, the electronic device includes a display assembly10for displaying images and a fixing assembly coupled to the display assembly10for fixing the display assembly10.

At least a part of the display assembly10has a first deformability. The display assembly10also includes a first part11and a second part12, which are disposed on two different sides of a first deformable part13. The first deformable part13is the part of the display assembly10having the first deformability and is capable of changing a relative angle between the first par11and the second part12, such that various angles may be formed between the first part11and the second part12of the display assembly10to make the display assembly10have various attitudes.

The fixing assembly includes at least a first fixing element20. At least a part of at least one of the first fixing element20or the display assembly10has a second deformability. The second deformability is capable of changing a length in a preset direction.

In some embodiments, at least a part of the first fixing element20has the second deformability. The second deformability is capable of changing a length of a second fixing element40in the preset direction. The second deformability makes an end of the display assembly10connected to the first fixing element20be at a free sliding state, capable of absorbing deformation caused by a change of the relative angle between the first part11and the second part12. As such, during a process of changing the relative angle between the first part11and the second part12, a stress on the first deformable part13of the display assembly10is mitigated, and the failure rate of the first deformable part13of the display assembly10is reduced. Thus, the reliability of the electronic device is improved.

In some embodiments, the second deformability of at least a part of the first fixing element20may be the deformability of only a part of the first fixing element20or of the entire first fixing element20. That is, any and every part of the first fixing element20has the second deformability. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, at least a part of the display assembly10has the second deformability. The second deformability is capable of changing the length of the display assembly10in the preset direction. As such, in the process of changing the relative angle between the first part11and the second part12, the second deformability of the display assembly10mitigates the stress on the first deformable part13of the display assembly10, and reduces the failure rate of the first deformable part13of the display assembly10in the process of changing the relative angle between the first part11and the second part12. Thus, the reliability of the electronic device is improved.

In some embodiments, changing the relative angle between the first part11and the second part12may be increasing the relative angle between the first part11and the second part12or decreasing the relative angle between the first part11and the second part12. It depends on specific circumstances and is not limited by the present disclosure. The relative angle between the first part11and the second part12refers to an angle formed between the first part11and the second part12.

In some embodiments, when the relative angle between the first part11and the second part12is between 0° and 180° excluding 180°, the first part11and the second part12are facing toward each other. That is, the display assembly10is in an inward bended attitude. In some other embodiments, when the relative angle between the first part11and the second part12is between 0° and 180° excluding 180°, the first part11and the second part12are facing opposite to each other. That is, the display assembly10is in an outward bended attitude. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, the first deformability supports switching the display assembly10from a first attitude to a second attitude. In the first attitude, as shown inFIG.1, the first part11and the second part12of the display assembly10satisfy a coplanar condition. In the second attitude, as shown inFIG.2, the first part11and the second part12satisfy an overlapping condition.

In some embodiments, the coplanar condition satisfied by the first part11and the second part12of the display assembly10may be that the first part11and the second part12of the display assembly10are located at a same plane or that the first part11and the second part12of the display assembly10are located almost at a same plane. That is, in the embodiments of the present disclosure, the first part11and the second part12of the display assembly10are located at the same plane or first part11and the second part12of the display assembly10are located almost at the same plane. In this case, the display assembly10is in an extended attitude. The overlapping condition satisfied by the first part11and the second part12of the display assembly10may be that the first part11and the second part12of the display assembly10are at least partially overlapped. That is, the relative angle between the first part11and the second part12of the display assembly10is not equal to 180°, and the display assembly10is in a bended attitude.

In some embodiments, although only the first attitude and the second attitude are described, and the first deformability supports switching the display assembly10from the first attitude and the second attitude. The present disclosure is not limited thereto. In some other embodiments, the first deformability also supports switching the display assembly10from the second attitude to the first attitude, and the display assembly10may have additional attitudes. When the display assembly10has other attitudes, the first deformability supports switching the display assembly10between any two attitudes depending specific circumstances.

In practical applications, after the display assembly10is switched from the bended attitude to the extended attitude, a residual stress may still exist when the display assembly10is previously switched from the extended attitude to the bended attitude, which may prevent the first deformable part from resuming its initial state and causes wrinkles at the first deformable part of the display assembly10. This is more likely to occur after the attitude of display assembly10has been switched multiple times.

In some embodiments, in the first attitude, the first fixing element20provides a pulling force to the display assembly10. Pulled by the pulling force, the first part11and the second part12are moving away from each other to mitigate the wrinkles occurred at the first deformable part13of the display assembly10.

In some embodiments, in the first attitude, the first fixing element20provides the pulling force to the display assembly10. Pulled by the pulling force, the first part11and the second part12are moving away from each other to make the first part11, the second part12, and the first deformable part13of the display assembly10satisfy the coplanar condition, thereby avoiding the wrinkles occurred at the first deformable part13of the display assembly10.

In some embodiments, in the first attitude, the pulling force provided by the first fixing element20to the display assembly10is greater than a force keeping the first deformable part13of the display assembly10in a wrinkle state, such that the pulling force provided by the first fixing element20to the display assembly10flattens a region of the first deformable part of the display assembly10where the wrinkles occur. Thus, in the first attitude, the first part11, the second part12, and the first deformable part13of the display assembly10satisfy the coplanar condition.

In some embodiments, satisfying the coplanar condition by the first part11, the second part12, and the first deformable part13of the display assembly10includes that the first part11, the second part12, and the first deformable part13of the display assembly10are located at the same plane or that the first part11, the second part12, and the first deformable part13of the display assembly10are located almost at the same plane. If the first part11and the second part12are located at the same plane, satisfying the coplanar condition includes that the first deformable part13of the display assembly10are located almost at the same plane as the first part11and the second part12or that the first part11and the first deformable part13of the display assembly10are located at the same plane and the second part12is located almost at the same plane as the first part11and the first deformable part of the display assembly10or that any two of the first part11, the second part12, and the first deformable part of the display assembly10are located almost at the same plane.

In some embodiments, the second deformability is capable of resuming to a natural state in a direction opposite to the preset direction. In some embodiments, in the first attitude, the first fixing element20tends to resume the natural state in the direction opposite to the preset direction. The tendency of the first fixing element20resuming the natural state provides the pulling force to the display assembly10to make the first part11and the second part12have at least a tendency to move away from each other.

In some embodiments, the at least tendency of the first part11and the second part12to move away from each other includes that the first part11and the second12only have the tendency to move away from each other but have not move away from each other or that the first part11and the second part12not only have the tendency to move away from each other, but also move away from each other. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, at least a part of the first fixing element20and at least a part of the display assembly10both have the second deformability. A deformation trigger threshold of the second deformability of the second deformable part of the first fixing element20is smaller than the deformation trigger threshold of the second deformability of the second deformable part of the display assembly10. That is, a stiffness coefficient of the second deformable part of the first fixing element20is smaller than the stiffness coefficient of the second deformable part of the display assembly10. In the processing of changing the relative angle between the first part11and the second part12, the deformable part of the first fixing element20deforms before the deformable part of the display assembly10deforms. Thus, the stress that occurs in the process of changing the relative angle between the first part11and the second part12is first applied to the first fixing element20, thereby reducing the failure rate of the display assembly10due to the stress.

Moreover, when the deformation trigger threshold of the second deformability of the second deformable part of the first fixing element20is smaller than the deformation trigger threshold of the second deformability of the second deformable part of the display assembly10, in the process of changing the relative angle between the first part11and the second part12, the first fixing element20extends first before the display assembly10extends, thereby avoiding the wrinkles that occur when the display assembly10resumes to the initial state after being pulled.

The stiffness coefficient, also known as rigidity coefficient or firmness coefficient (i.e., elastic coefficient), is used to describe a magnitude of an elastic force generated by a unit amount of deformation. The greater the stiffness coefficient, the greater force needed for a unit length of deformation. The smaller the stiffness coefficient, the smaller force needed for the unit length of deformation. Taking a spring as an example, the stiffness coefficient is numerically equal to the elastic force when the spring is extended (or shortened) per unit length.

In some embodiments, when the length in the preset direction of at least one of the first fixing element20or the display assembly10changes, the length of the electronic device in the present direction may also change. The present disclosure does not limit thereto. In some other embodiments, when the length in the preset direction of at least one of the first fixing element20or the display assembly10changes, the length of the electronic device in the present direction may not change. It depends on specific circumstances and is not limited by the present disclosure.

In the following description, when the length in the preset direction of at least one of the first fixing element20or the display assembly10changes, the length of the electronic device in the present direction may also change.

In some embodiments, the preset direction includes a first direction. The second deformability capable of changing a length in the first direction changes the length of the electronic device in the first direction.

In some embodiments, at least a part of the first fixing element20has the second deformability. The second deformability is capable of changing the length of the first fixing element20in the first direction and hence changing the length of the electronic device in the first direction. In some embodiments, at least a part of the display assembly10has the second deformability. The second deformability is capable of changing the length of the display assembly10in the first direction and hence changing the length of the electronic device in the first direction. In some embodiments, at least a part of the first fixing element20and at least a part of the display assembly10both have the second deformability. The second deformability is capable of changing the length of the first fixing element20in the first direction and the length of the display assembly10in the first direction and hence changing the length of the electronic device in the first direction.

In some embodiments, the electronic device includes a first surface having a first side and a second side opposite to each other. In the first attitude, the first surface of the electronic device and a display panel of the display assembly10satisfy the coplanar condition. The first side is located at a side of first part11facing away from the second part12. The second side is located at a side of the second part12facing away from the first part11. In some embodiments, the length of the electronic device in the first direction is a distance between the first side and the second side of the first surface.

In some embodiments, at least a part of the first fixing element20has the second deformability. The display assembly10does not have the second deformability. A maximum amount of deformation supported by the first fixing element20is greater than a maximum extension length of the electronic device. As such, when the electronic device is bended to the maximum extent, breakage or failure of the of at least a part of the display assembly10is avoided. In some embodiments, the first fixing element20does not have the second deformability. At least a part of the display assembly10has the second deformability. The maximum amount of deformation supported by the display assembly10is greater than the maximum extension length of the electronic device. As such, when the electronic device is bended to the maximum extent, breakage or failure of the at least a part of the display assembly10is avoided. In some embodiments, at least a part of the first fixing element20has the second deformability. At least a part of the display assembly10has the second deformability. A sum of the maximum amount of deformation supported by the first fixing element20and the maximum amount of deformation supported by the display assembly10is greater than the maximum extension length of the electronic device. As such, when the electronic device is bended to the maximum extent, breakage or failure of the of at least a part of the display assembly10is avoided.

In some embodiments, the maximum extension length of the electronic device refers to an amount of increase of the length of the electronic device in the first direction when the electronic device is bended to the maximum extent as compared to the length of the electronic device in the first direction when the electronic device is at the extended state.

In some embodiments, the preset direction includes a second direction. The second deformability is capable of changing the length in the second direction. The second direction is perpendicular to the display panel. That is, the second direction is perpendicular to a plane where the display panel is located or is approximately perpendicular to the plane where the display panel is located.

In some embodiments, at least a part of the first fixing element20has the second deformability. The second deformability is capable of changing the length of the first fixing element20in the second direction. In some other embodiments, at least a part of the display assembly10has the second deformability. The second deformability is capable of changing the length of the display assembly10in the second direction.

In some embodiments, the first fixing element20may be fixedly connected to the first part11or the second part12. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, in the first attitude, the first fixing element20and the display assembly10satisfy the coplanar condition. That is, the first fixing element20is disposed at a side of the display assembly10.

In some embodiments, as shown inFIG.3, the electronic device includes a first structural member31located at a side of the display assembly10. The first fixing element20is located between the display assembly10and the first structural member31. A first end of the first fixing element20is connected to an end surface of the display assembly10facing toward the first structural member31. A second end of the first fixing element20is connected to an end surface of the first structural member31facing toward the display assembly10. That is, the first fixing element20is located at a side of the display assembly10.

In some embodiments, because the first structural member31is located at the side of the display assembly10, and the first fixing element20is located between the side of the display assembly10and the first structural member31, the second deformability of the first fixing element20is capable of changing the length in the direction from the connection end between the first fixing element20and the display assembly10to the connection end between the first fixing element20and the first structural member31.

In some embodiments, when the display assembly10is in the first attitude, the direction along the first fixing element20from the connection end between the first fixing element20and the display assembly10to the connection end between the first fixing element20and the first structural member31and the first direction satisfy the coplanar condition. That is, the direction along the first fixing element20from the connection end between the first fixing element20and the display assembly10to the connection end between the first fixing element20and the first structural member31and the first direction are located in the same plane or almost in the same plane. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, the first structural member31may be arranged around the display assembly10as shown inFIG.4, or may be located in certain regions around the display assembly10, as shown inFIG.3. The present disclosure does not limit thereto. As long as it is ensured that at least a part of the first structural member31is located in certain regions around the display assembly10, the first fixing element20may be located between the side of the display assembly10and the first structural member31, and the display assembly10and the first structural member31are fixedly connected.

In some embodiments, the first structural member31may not be located at the side of the display assembly10, and instead, may be located beneath the display assembly10. As such, the second deformability of the first fixing element20is capable of changing the length of first fixing element20in the second direction. It depends on specific circumstances and is not limited by the present disclosure.

The electronic device consistent with the embodiments of the present disclosure is described below assuming that the first structural member31is located at the side of the display assembly10.

In some embodiments, the first fixing element20is an elastic element having the second deformability. The elastic feature of the first fixing element20is capable of changing the length of the first fixing element20in the preset direction.

In some embodiments, as shown inFIG.5, a fixing assembly includes two first fixing elements20and two second fixing elements40. The display assembly10includes the first side and the second side opposite to each other. The two first fixing elements20, located between the first side of the display assembly10and the end surface of the first structural member31facing toward the first side, fixedly connect the display assembly10and the first structural member31. The two second fixing elements40, located between the second side of the display assembly10and the end surface of the first structural member31facing toward the second side, fixedly connect the display assembly10and the first structural member31.

In some embodiments, the first side is the side of the first part11facing away from the second part12, and the second side is the side of the second part12facing away from the first part11. The two first fixing elements20and the first part11are fixedly connected, and the two second fixing elements40and the second part12are fixedly connected. The present disclosure does not limit thereto. In some other embodiments, the two first fixing elements20and the second part12are fixedly connected, and the two second fixing elements40and the first part11are fixedly connected. It depends on specific circumstances and is not limited by the present disclosure.

For illustration purpose, the first fixing elements20and the first part11are fixedly connected. In some embodiments, the display assembly10further includes a third side and a fourth side, which are connected to the first side and the second side. One of the two first fixing elements20is fixed to a region of the first side adjacent to the third side.

In some embodiments, the two first fixing elements20have the second deformability. The two second fixing elements40do not have the second deformability. The second deformability of the two first fixing elements20mitigates the stress on the first deformable part13of the display assembly10in the process of changing the relative angle between the first part11and the second part12, reduces the failure rate of the first deformable part13of the display assembly10, and improves the reliability of the electronic device.

In some embodiments, as shown inFIG.6, the fixing assembly includes four first fixing elements20. The fixing assembly includes the first side and the second side opposite to each other. Two of the four first fixing elements20, located between the first side of the display assembly10and the end surface of the first structural member31facing toward the first side, fixedly connect the display assembly10and the first structural member31. Another two first fixing elements20, located between the second side of the display assembly10and the end surface to the first structural member31facing toward the second side, fixedly connect the display assembly10and the structural member31. The second deformability of the four first fixing elements20mitigate the stress on the first deformable part13of the display assembly10in the process of changing the relative angle between the first part11and the second part12, reduces the failure rate of the first deformable part13of the display assembly10, and improves the reliability of the electronic device.

In some embodiments, the four first fixing elements20are evenly distributed around the sides of the display assembly10. Specifically, in some embodiments, the display assembly10includes four sides. The four first fixing elements20are located at transition regions between any two adjacent sides of the four sides. The present disclosure does not limit thereto. In some embodiments, the four first fixing elements20may also be disposed differently, for example, in connection regions between adjacent sides of the display assembly10. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, the first fixing element20may be an elastic element such as a spring element or a rubber element. The present disclosure does not limit thereto. In some embodiments, the first fixing element20may also be a retractable rod. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, in the first attitude, the first fixing element20may not satisfy the coplanar condition with the display assembly10. Correspondingly, the first fixing element20may be stacked with the display assembly10or may form an angle with the display assembly10. It depends on specific circumstances and is not limited by the present disclosure.

When the first fixing element20is stacked with the display assembly10and at least a part of the first fixing element20has the second deformability, the second deformability is capable of changing the length of the first fixing element20in the centerline direction of the first fixing element20. The centerline direction of the first fixing element20may satisfy the coplanar condition with the first direction, or may satisfy the coplanar condition with the second direction, or may form an angle with the first direction or the second direction. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, as shown inFIG.7, the electronic device further includes a structural member. The structural member includes a second structural member32located at a side of the display assembly10facing away from the display panel. The first fixing element20, located between the display assembly10and the second structural member32, fixedly connect the display assembly10and the second structural member32.

In some other embodiments, the second deformability is capable of changing the length in the third direction and the length in the fourth direction. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, the third direction and a contact surface between the first fixing element20and the display assembly10satisfy the coplanar condition. That is, the third direction and the contact surface between the first fixing element20and the display assembly10are located in the same plane or approximately in the same plane. The fourth direction and the contact surface between the first fixing element20and the display assembly10satisfy the perpendicular condition. That is, the fourth direction and the contact surface between the first fixing element20and the display assembly10are perpendicular with each other or approximately perpendicular with each other.

In some embodiments, the fixing assembly includes two first fixing elements20. One of the two first fixing elements20fixedly connects between the first part11and the first structural member31. Another first fixing element20fixedly connects between the second part12and the second structural member32. In some embodiments, to facilitate the first fixing element20to change the length in the third direction and/or the fourth direction, a gap exist between the two first fixing elements20. The gap corresponds to the first deformable part13of the display assembly10. In the process of changing the relative angle between the first part11and the second part12, the gap between the two first fixing elements20accommodates the amount of deformation of the first fixing element20and the second fixing element40.

In some embodiments, the gap between the two first fixing elements20has a length in the contact surface between the first fixing element20and the display assembly10in the direction from the first fixing element20to the second fixing element40, that is tens of times a minimum bending radius of the first deformable part13of the display assembly10. In the process of bending the display assembly10, the first fixing element20may more effectively absorb the deformation formed in the process of changing the relative angle between the first part11and the second part12. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, the second structural member32may include a plurality of sub-structural members. As shown inFIG.7, different first fixing elements20are fixedly connected to different sub-structural members. The second structural member32may also be a single-piece structural member. As shown inFIG.8, different first fixing elements20are fixedly connected to the single-piece second structural member32. It depends on specific circumstances and is not limited by the present disclosure. The second structural member32may include the plurality of sub-structural members. When different first fixing elements20are fixedly connected to different sub-structural members, gaps may exist between adjacent sub-structural members, as shown inFIG.7, or may not exist between adjacent sub-structural members, as shown inFIG.9. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, the second structural member32includes a support member for fixing configuration of the first part11and the second part12. Specifically, in some embodiments, the second structural member32is the support member, thereby simplifying the structure of the electronic device. In some embodiments, the support member is only a part of the second structural member32. In some embodiments, the second structural member32is at least a part of a mainboard of the electronic device. That is, the second structural member32may be a certain part of the mainboard or may be the mainboard itself. In some embodiments, the second structural member32may also be a structure combining the support member and the mainboard. The present disclosure does not limit thereto. In some other embodiments, the second structural member32may be another structure of the electronic device. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, the elastic member includes a fixed connection feature and may directly fixedly connect between the display assembly10and the second structural member32. In some embodiments, the elastic member does not include the fixed connection feature. In some embodiments, the first fixing element20further includes another fixing element for fixedly connecting between the elastic member and the display assembly10and for fixedly connecting between the elastic member and the second structural member32.

In some embodiments, as shown inFIG.10, the first fixing element20further includes a first bonding member22for bonding a first surface of an elastic member21with the display assembly10and a second bonding member23for bonding a second surface of the elastic member21with the second structural member32. The first bonding member22fixedly connect between the elastic member21and the display assembly10. The second bonding member23fixedly connect between the elastic member21and the second structural member32. The second surface of the elastic member21and the first surface of the elastic member21are opposite to each other.

In some embodiments, the elastic member21is an elastic member formed by a highly elastic material layer such as an elastic film or a highly elastic rubber. The first bonding member22includes an adhesive tape or an adhesive coating. Similarly, the second bonding member23includes the adhesive tape or the adhesive coating. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, the first bonding member22and the second bonding member23are elastic members covered by the adhesive layers formed by coating double-sided adhesive. In some embodiments, the first bonding member22and the second bonding member23are elastic members covered by the adhesive layers formed by coating optical clear adhesive (OCA) film. In some embodiments, the first bonding member22and the second bonding member23are elastic members covered by the adhesive layers formed by coating a pressure-sensitive adhesive (such as acrylic pressure-sensitive adhesive). In some embodiments, the first bonding member22and the second bonding member23are elastic members covered by the adhesive layers formed by coating another material. It depends on specific circumstances and is not limited by the present disclosure.

In some embodiments, as shown inFIG.11, the deformation trigger threshold of the second deformability of the first fixing element20is smaller than a preset force. The preset force is the smallest force among a first force, a second force, a third force, and a fourth force. The first force is capable of separating the first bonding member and the display assembly10. The second force is capable of separating the first bonding member and the elastic member. The third force is capable of separating the second bonding member and the elastic member. The fourth force is capable of separating the second bonding member and the second structural member. In the process of changing the relative angle between the first part11and the second part12, before the elastic member is separated from the display assembly10and/or the second fixing element, the first fixing element20deforms first to avoid a debonding symptom, such as the separation between the elastic member and the display assembly10or the separation between the elastic member and the second structural member32in the process of changing the relative angle between the first part11and the second part12. As such, moisture and dust are prevented from entering the gaps between the display assembly10and the first fixing element20after the separation, thereby improving the reliability of the display assembly10.

In some embodiments, the deformation trigger threshold of the second deformability of the first fixing element20is also smaller than a connection force between various film layer structures inside the display assembly10to avoid cracks of the various film layers inside the display assembly10in the process of changing the relative angle between the first part11and the second part12, thereby preventing foreign objects from entering the display assembly10causing protrusions and poor appearance.

In some embodiments, the maximum amount of deformation supported by the elastic member in the preset direction is greater than the maximum extension length of the display assembly10in the preset direction to avoid break or failure of at least a part of the display assembly10when the electronic device is bended to the maximum extent. Specifically, the maximum amount of deformation supported by the elastic member in the third direction is greater than the maximum extension length of the display assembly10in the third direction. The maximum amount of deformation supported by the elastic member in the fourth direction is greater than the maximum extension length of the display assembly10in the fourth direction.

In some embodiments, the maximum extension length of the display assembly10in the preset direction is the extension length of the display assembly10in the preset direction when the display assembly10is bended to the maximum extent.

Further, the electronic device provided by the embodiments of the present disclosure includes the display assembly and the fixing assembly. The fixing assembly includes at least one fixing element. At least a part of at least one of the first fixing element and the display assembly includes the second deformability. The second deformability is capable of changing the length in the preset direction. In the process of changing the relative angle between the first part and the second part, the second deformability of the first fixing element and/or the display assembly mitigates the stress on the first deformable part of the display assembly, reduces the failure rate of the first deformable part of the display assembly in the process of changing the relative angle between the first part and the second part, and improve the reliability of the electronic device.
