All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In prior foldable display devices, the support assembly is generally attached directly to the back of the flat display assembly. That is, the initial flattened state display assembly and the support assembly are the same length. When the display device is bent, the display assembly is subjected to tensile deformation at the bent position, so that the length of the bent position is increased, and when the display device is restored to the flat state again, the bent portion is wrinkled due to the increase of the length of the bent portion, so that the flatness is poor.
In order to solve the above problem, an embodiment of the present application provides a display device, including:
a display assembly having opposing first and second surfaces, the first surface being a display surface, wherein at least a portion of the display assembly has a deformation capability, the deformation capability comprising a capability of having a first portion and a second portion change relative angles, the first portion and the second portion being located on different sides of the portion having the deformation capability;

wherein, after the coplanarity condition is satisfied, the first support applies an external force to the first portion away from the second portion and/or the second support applies an external force to the second portion away from the first portion.
In the display device according to the embodiment of the application, the first support applies an external force far away from the second portion to the first portion and/or the second support applies an external force far away from the first portion to the second portion, so that tension in opposite directions can be provided for the local portion, and flatness of the display assembly in the local portion is ensured.
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a display device provided in an embodiment of the present application when a first surface does not satisfy a plane condition, and fig. 2 is a schematic structural diagram of a display device provided in an embodiment of the present application when a first surface satisfies a plane condition. The display device includes: a display assembly 11 having opposing first and second surfaces 111, 112, the first surface 111 being a display surface; the supporting member 12, disposed on the second surface, includes a first supporting member 121 corresponding to the first portion a1 and a second supporting member 122 corresponding to the second portion a 2.
In the first supporting assembly 12, the first supporting member 121 and the second supporting member 122 may be metal members, ceramic members, glass members, alloy members, hard plastic members, or other members without deformation capability.
At least the portion A3 of the display element 11 has a deformation capability that includes the ability to allow the first portion AA and the second portion A2 to change relative angles. The first part A1 and the second part A2 are located on different sides of a part A3 with deformation capability, for example, the first part A1 and the second part A2 are opposite sides of the part A3, and the part 23 is located between the first part A1 and the second part A2.
The first support member 121 and the second support member 122 do not have the deformation capability. If the first support 121 and the second support 122 satisfy the coplanar condition, the first surface 111 can be made to satisfy the planar condition. Wherein, upon satisfaction of the coplanar condition, the first support 121 applies an external force to the first portion a1 away from the second portion a2 and/or the second support 122 applies an external force to the second portion a2 away from the first portion a 1. The first support 121 and the second support 122 apply external forces to the first portion a1 and the second portion 2, which are far away from each other, and based on this, the local A3 will be subjected to two opposite pulling forces, so that the first surface 111 can be flattened and has better flatness after meeting the planar condition.

The first support 121 corresponds to the first portion A1 and to a portion of the section A3, and the second support 122 corresponds to the second portion A2 and to another portion of the section A3.
The first support 121 and the second support 122 satisfying the coplanar condition include that a surface of the first support 121 facing the first portion a1 and a surface of the second support 122 facing the second portion a2 are flush, or approximately flush. The first surface 111 satisfying the planar condition includes the first portion a1, the second portion a2, and the part A3 being located on the same plane, or approximately on the same plane.
In the display device according to the embodiment of the application, the first support 121 applies an external force far away from the second portion a2 to the first portion a1 and/or the second support 122 applies an external force far away from the first portion a1 to the second portion, so as to provide a pulling force in an opposite direction to the local portion A3, thereby ensuring the flatness of the display assembly 11 in the local portion.
In the display device according to the embodiment of the application, if the first surface 111 satisfies the plane condition, the first support 121 and the second support 122 are abutted, and in the position where the first support 121 and the second support 122 are abutted, the first support 121 applies a thrust force to the second support 122 toward the second support 122, and the second support 122 applies a thrust force to the first support 121 toward the first support 121, so that the first support 121 and the second support 122 have a mutual pressing thrust force therebetween, and the thrust force can cause the first support 121 to apply an external force to the first portion a1 away from the second portion a2, and cause the second support 122 to apply an external force to the second portion away from the first portion a 1. The butting means that objects are in direct or indirect contact and have mutual thrust.
In the manner shown in fig. 1 and 2, the first side C1 of the first support 121 is disposed opposite to the second side C2 of the second support 122; the side of the first side surface C1 close to the display module 11 and the side of the second side surface C2 close to the display module 11 satisfy a common edge overlapping condition, and the first side surface C1 and the second side surface C2 can be based on the overlapped two edges as a rotation reference. Both coinciding edges are parallel to the display element 11. If the first support 121 and the second support 122 satisfy the coplanar condition, the first side C1 is in relatively coincident abutment with the second side C2. Wherein, the meeting the common edge coincidence condition comprises: the side of the first side C1 parallel to and proximate to the display element 11 coincides with or approximately coincides with the side of the second side C2 parallel to and proximate to the display element 11 such that the support element 12 is capable of being rotationally referenced based on the coincident abutment positions.
In the display device shown in fig. 1 and 2, if the first surface 111 satisfies the plane condition, the first side surface C1 and the second side surface C2 coincide and are in direct contact abutment.
As shown in fig. 3 and 4, fig. 3 is a schematic structural diagram of another display device provided in the embodiment of the present application when the first surface does not satisfy the plane condition, and fig. 4 is a schematic structural diagram of another display device provided in the embodiment of the present application when the first surface satisfies the plane condition. In this embodiment, the first support 121 and the second support 122 are in contact with each other via a rotating shaft 13, and both are relatively rotatable based on the rotating shaft. At this time, the first side surface C1 and the second side surface C2 may be concave curved surfaces respectively fitted to the rotation shaft 13, so that both the first supporting member 121 and the second supporting member 122 can rotate based on the rotation shaft 13.
As shown in fig. 5 and 6, fig. 5 is a schematic structural diagram of another display device provided in the embodiment of the present application when the first surface does not satisfy the plane condition, and fig. 6 is a schematic structural diagram of another display device provided in the embodiment of the present application when the first surface satisfies the plane condition.

At this time, the first side C1 and the second side C2 may be flat surfaces opposite to the elastic member 14 or concave curved surfaces surrounding the ends of the elastic member. The elastic component 14 can be a spring component or a gooseneck, which is stretchable, bendable, compressible and has a compression resilience.
As shown in fig. 7, fig. 7 is a schematic structural diagram of an electronic device in a first posture provided in an embodiment of the present application, and the first portion a1 and the second portion a2 can be switched between the first posture and the second posture by changing relative angles. Wherein, in the first posture, the display surface of the first part a1 and the display surface of the second part a2 satisfy a relative condition. The satisfying of the relative condition includes: the display surface of the first portion a1 and the display surface of the second portion a2 are relatively parallel, or approximately parallel.
The display device is the turn-in display device, and based on the rotation of two supporting pieces of the supporting component 12, the part A3 of the display component 11 can be bent towards the display side, and the relative angle between the color development surface of the first part A1 and the color development surface of the second part A2 is changed.
In the second posture, as shown in fig. 6, the display surface of the first part a1 and the display surface of the second part a2 satisfy the plane condition.
It should be noted that, in the embodiment of the present application, only in the manner shown in fig. 6 and 7, the exemplary display device is capable of switching the posture between the first posture and the second posture and any position between the two postures to change the relative angle of the first portion a1 and the second position a 2. The connection structure for adjusting the posture of the electronic device is not limited to the embodiment of the present application, and may be other connection methods capable of achieving this effect, such as a method of connecting the first support 121 and the second support 122 by a hinge.
As described in the above embodiments, in the display device according to the embodiment of the present application, the first side surface C1 of the first supporting member 121 is disposed opposite to the second side surface C2 of the second supporting member 122; if the first support 121 and the second support 122 satisfy the coplanar condition, the first side C1 and the second side C2 abut against each other, and as described in the above embodiments, the first side C1 and the second side C2 may abut against each other directly or via other means, such as a hinge, an elastic element, and a hinge.
In the display device according to the embodiment of the application, the back surface of the first portion a1 is attached and fixed to the first support member 121 by a first adhesive member 21, and the back surface of the second portion a2 is attached and fixed to the second support member a2 by a second adhesive member 22. In order to ensure the flatness of the first part a1, the first part a1 is provided with complete security covered by the first adhesive 21, and in order to ensure the flatness of the second part a2, the back side of the second part a2 is provided with security covered by the second adhesive 22. The first adhesive member 21 and the second adhesive member 22 may be glue.
In the manner shown in fig. 1 and 2, the sides of the first support member 121 opposite to the second support member 122 have a common edge which is coincident and parallel to the display module 11 and is a side edge of the first side surface C1 and the second side surface C2 close to the display module 11, and the common edge becomes a rotation reference. The end of the first adhesive member 21 away from the second adhesive member 22 is a first end, and the end of the second adhesive member 22 away from the first adhesive member 21 is a second end.
If the first surface 111 does not satisfy the planar condition, the display component 11 has a first length between the first end and the second end, and the first length is a length within the first surface 111. The sum of the length from the first position on the first support 121 to the end facing the second support 122 and the length from the second position on the second support 122 to the end facing the first support 121 is a second length; the second length is greater than the first length. The first position is a position on the first support 121 corresponding to the first end, and the second position is a position on the second support 122 corresponding to the second end.
Thus, in the posture shown in fig. 1, the length (i.e., the second length) between the first end and the second end of the two supporting members is greater than the length (i.e., the first length) between the first end and the second end of the first surface 111, so when the posture shown in fig. 2 is switched, the two supporting members cannot be compressed because of no deformation capability, the length is not changed, and the second length is still between the first end and the second end.
The portion A3 having a deformation capability includes the portion A3 having a first deformation property, the first deformation capability including the ability of the portion to bend and not be stretched. If the portion A3 of the display module 11 cannot be stretched and the first length of the display module 11 does not change, it is necessary to make the first adhesive member 21 and the second adhesive member 22 have elasticity and can be stretched to be stretched toward the middle of the display module 11, so as to buffer the difference between the first length and the second length, thereby making the portion A3 be stretched tightly and flat with better flatness.
The portion A3 having a deformation capability includes the portion A3 having a second deformation capability, the second deformation capability including the ability of the portion to be bendable and stretchable. If the portion A3 of the display module 11 can be stretched, the first adhesive member 21 and the second adhesive member 22 may not be elastic and can not be stretched, and the first length of the display module 11 is increased to be equal to the second length due to the stretching of the portion A3, and is also pulled straight, thereby having better flatness. Obviously, at this time, the first adhesive member 21 and the second adhesive member 22 may have elasticity and be capable of being stretched.
The first adhesive member 21 has a first distance L1 from the first side C1, the second adhesive member 22 has a second distance L2 from the second side C2, and the first distance L1 and the second distance L2 correspond to a local a3 of the display assembly 11 having the deformation capability; if the first surface 111 does not satisfy the plane condition, the sum of the first distance L1 and the second distance L2 is greater than the length of the portion. That is, in the position shown in fig. 1, the length of the two supporting members corresponding to the part A3 is greater than the length of the part A3, so that when in the position shown in fig. 2, the part A3 will be pulled straight to make the display assembly 11 have better flatness, regardless of whether the part A3 has elasticity to be stretched.
As shown in fig. 8, fig. 8 is a schematic structural diagram of a display device according to an embodiment of the present disclosure, based on the above embodiment, in the display device shown in fig. 8, a side of the supporting component 12 facing away from the display component 11 is provided with a limiting part 15, and the limiting part 15 is fixed to one of the first supporting member 121 and the second supporting member 122 and is movable relative to the other one, so as to enable the first supporting member 121 and the second supporting member 122 to be only bent toward the display surface.
In the embodiment shown in fig. 8, the embodiment shown in fig. 1 and 2 is merely described as an example, and the stopper member 15 may be provided in other embodiments of the present application in the same manner.
As shown in fig. 9, fig. 9 is a schematic structural view of another display device provided in the embodiment of the present application, based on the above embodiment, in the display device shown in fig. 9, a spring 16 is attached to the back surface of the part A3, and the spring 16 is used for bending the part A3 in a curved surface under the condition that the first supporting member 121 and the second supporting member 122 rotate, so as to prevent the display module 11 from being damaged due to bending at a break angle.
In the embodiment shown in fig. 9, the embodiment shown in fig. 1 and fig. 2 is merely used as an example for description, and the elastic sheet 16 may be provided in other embodiments of the present application in the same manner.
The electronic device according to the embodiment of the present application may further include a housing, wherein the supporting component 12 and the display component are located in the accommodating cavity of the housing, and the display surface of the display component 11 is exposed from the housing, so as to facilitate image display.
This application embodiment electronic equipment can provide pulling force when satisfying the plane condition for display module 11 through two support piece of direct butt or indirect butt to make it tighten and flare-out, with better planarization has.
