A display assembly and an electronic device provided according to an embodiment of the present application are described below with reference to fig. 1 to 9.
As shown in fig. 1 and 3, one embodiment of the present application proposes a display assembly 100 comprising: a flexible display panel 101 and a magnetic support 102, the magnetic support 102 being provided at one side of the flexible display panel 101; the flexible display panel 101 includes a magnetic layer 106, the magnetic layer 106 is located at a bending portion 1012 of the flexible display panel 101, and the magnetic support 102 is disposed opposite to the magnetic layer 106; the magnetic support 102 moves at least a portion of the curved portion 1012 toward a direction approaching the magnetic support 102 through the magnetic layer 106.
According to the embodiment of the display assembly 100 provided by the application, the display assembly mainly comprises a flexible display panel 101 and a magnetic support member 102, the magnetic support member 102 mainly plays a role in supporting the whole display assembly 100, the possibility that the internal local structure falls off is prevented, the magnetic support member 102 is arranged on one side of the flexible display panel 101, acting force is generated between the magnetic support member 102 and the magnetic layer 106 under the action of the magnetic layer 106 arranged in the flexible display panel 101, and accordingly the bending area of the flexible display panel 101, namely the crease of the bending part 1012, is relieved. It will be appreciated that a plurality of laminated structures are also provided inside the flexible display panel 101, the laminated structures being mainly used for achieving a display effect. Because of the number of stacked structures, the optical adhesive is mainly used for bonding and fixing when fixing, however, because of creep property of the optical adhesive, when the flexible display panel 101 is not bent, the position of the optical adhesive does not change greatly, but when the display assembly 100 is used on a folding device, the optical adhesive near the bending portion 1012 is stacked to two sides, so that the flexible display panel 101 at the central part is lower, and the flexible display panels 101 at the two sides are higher, namely uneven folds appear. In this case, the magnetic layer 106 is disposed in the flexible display panel 101, and a certain magnetic force exists between the magnetic layer 106 and the magnetic support member 102 disposed opposite to the magnetic layer, and it needs to be described that under the action of the magnetic force of the magnetic layer and the magnetic support member, a part of the bending portion 1012 or the whole bending portion 1012 faces the direction close to the magnetic support member 102, so that the distance between the whole flexible display panel 101 and the magnetic support member 102 is relatively balanced, and the crease effect is relieved.
It should be noted that, the bending portion 1012 is a portion of the display assembly 100 that is deformed when bending occurs, and the portion is easily creased due to multiple bending.
Since the whole display assembly 100 needs an external display interface, the cover plate and the internal lamination structure need to ensure no shielding on the path of the light emitted from the display screen, thereby ensuring the display effect.
It should be emphasized that when the flexible display panel 101 is folded, the internal optical adhesive is subjected to extrusion stress, and the optical adhesive moves from the center to the two sides by combining the creep characteristic of the optical adhesive, so that the more the folding times, the more obvious the moving effect is, that is, the more obvious the crease effect is. According to the scheme, the structure in the display assembly 100 is changed, under the action of the magnetic support piece 102, the magnetic layer 106 in the flexible display panel 101 is correspondingly arranged with the magnetic support piece 102, on the basis, under the action of the magnetic support piece 102 and the magnetic layer 106, the magnetic force of the magnetic support piece 102 and the magnetic layer 106 can be utilized, and the area with the higher crease bulges is attached to the magnetic support piece 102 as much as possible under the action of the magnetic force, so that a certain crease relieving effect can be achieved on the display assembly 100 in the bending part, and the crease formed after the display assembly 100 is folded is improved.
The magnetic support 102 may be in a staggered mesh shape, or may be in a plurality of strips.
Further, the flexible display panel 101 further includes a substrate 108, the magnetic support 102 is disposed on one side of the substrate 108, and the magnetic layer 106 is disposed on the other side of the substrate 108.
By arranging the substrate 108 and arranging the magnetic support 102 and the magnetic layer 106 on two sides of the substrate 108, the substrate 108 can play a certain supporting role for the flexible display panel 101, and can also play a fixing role for the magnetic layer 106, thereby providing support for the arrangement of the magnetic layer 106.
Further, the flexible display panel 101 further includes a substrate 108, the magnetic layer 106 is fixedly disposed on one side of the substrate 108, and the magnetic layer 106 is located between the substrate 108 and the magnetic support 102.
Through setting up base plate 108, set up the magnetic layer 106 in the one side of base plate 108 to set up the magnetic layer 106 between base plate 108 and magnetic support 102, the distance between magnetic layer 106 and the magnetic support 102 is shorter, and the magnetic force of both is stronger, can show the effect of alleviating to the crease.
The substrate 108 is made of polyimide (i.e., PI material), has the characteristics of high modulus, high strength, high and low temperature resistance, light weight, flame retardance, and the like, and can be processed into a thin film form in the scheme, and as the substrate 108108 with certain deformability, the substrate 108 made of PI material has stronger mechanical properties and chemical stability, thereby being more beneficial to prolonging the service life.

In addition, one or more functional films 1106 are further provided, on the one hand, specific functions, such as touch control, can be added to the functional films 1106, so that a touch control effect is achieved, on the other hand, since the display assembly 100 is folded, in order to prevent the screen from being damaged, better rigidity is utilized under the action of the functional films 1106, and a better protection effect is achieved. An ITO film (i.e., an indium tin oxide semiconductor transparent conductive film) is more commonly used, so that touch control of the screen can be achieved, and a BOPET film may be used for the functional film 1106 with a protective effect.

Further, the front projection of the magnetic layer 106 on the flexible display panel 101 covers the curved portion 1012.
In one aspect, for the position of the magnetic layer 106, the bending portion 1012 needs to be covered, so that the magnetic layer 106 drives the bending portion 1012 to adjust in the thickness direction under the action of the magnetic support 102, so that the creasing effect is reduced.

Further, the bending portion 1012 includes a bending portion 1014, the bending portion 1012 is bent along the bending portion 1014, the magnetic layer 106 includes a first magnetic portion, a second magnetic portion, and a third magnetic portion, the first magnetic portion is located in the bending portion 1014, and the second magnetic portion and the third magnetic portion are located on two sides of the first magnetic portion, respectively.

In addition to the above-mentioned structure of the magnetic layer 106, the magnetic layer 106 is a powder layer having magnetic properties, the volume of the first magnetic portion is smaller than the volume of the second magnetic portion, and the volume of the first magnetic portion is smaller than the volume of the third magnetic portion
In one embodiment, the powdered magnetic layer 106 is used to more easily fill the original laminate structure 110. After the display assembly 100 is continuously folded, the generated folding area has larger deformation on two sides, a larger amount of powder can be arranged on two sides, and the middle part can be less provided due to smaller deformation, namely, the volume of the powder on two sides of the bending part is larger than that of the powder on the middle position of the bending part, so that the positions on two sides of the fold mark can have larger magnetic force under the action of the magnetic support piece 102, and the middle magnetic force is smaller, so that the whole display assembly 100 can be more flattened.
Further, the magnetic layer 106 is a thin film layer having magnetic powder, the magnetic powder density in the first magnetic portion is smaller than the magnetic powder density in the second magnetic portion, and the magnetic powder density in the first magnetic portion is smaller than the magnetic powder density in the third magnetic portion.

Further, the magnetic layer 106 is a thin film layer having magnetic powder, the thickness of the first magnetic portion is smaller than the thickness of the second magnetic portion, and the thickness of the first magnetic portion is smaller than the thickness of the third magnetic portion.
In a specific embodiment, the film-shaped magnetic layer 106 is adopted, after the display assembly 100 is continuously folded, the resulting folding area has larger deformation on both sides, and can set thicker films on both sides, and the middle of the folding area can be thinner because of smaller deformation, i.e. the thickness of the films on both sides of the bending part is larger than that of the films on the middle position of the bending part, so that under the action of the magnetic support 102, the positions on both sides of the folding mark can have larger magnetic force, and the middle magnetic force is smaller, so that the whole display assembly 100 can be more flat.
Further, the flexible display panel 101 includes a coil adjacent to the curved portion 1012, and the coil forms a magnetic field when energized.

Further, as shown in fig. 8, the magnetic support 102 specifically includes: the net body 1022 is arranged opposite to the flexible display panel; wherein, the mesh 1022 is provided with at least one magnetic embedding region 1024 opposite to the coil 114, the magnetic embedding region 1024 has magnetism, and the magnetic field formed by energizing the coil covers the magnetic embedding region to generate magnetic force.
The magnetic support 102 mainly includes a mesh 1022 disposed opposite to the cover, and the mesh 1022 is disposed opposite to the cover 104, so that the display assembly 100 forms a whole and is more prone to bending. Meanwhile, by arranging the magnetic embedding region 1024 at the position opposite to the coil 114 on the net body 1022, after the coil 114 is electrified, the generated induction magnetic field is matched with the magnetic field of the magnetic embedding region 1024, and both sides of the bending part are moved towards the magnetic support 102 along the thickness direction, so that crease repairing is realized.
Further, the display assembly 100 specifically includes a first display region 1162 and a second display region 1164, the second display region 1164 is capable of being folded with respect to the first display region 1162, and a portion where the first display region 1162 and the second display region 1164 intersect forms a curved portion.
The display assembly 100 mainly includes a first display area 1162 and a second display area 1164 that are folded, and when the two display areas are folded, a portion where the two display areas meet forms a bending portion, and the portion is easy to crease.
As shown in fig. 9, an electronic device 200 provided in an embodiment of a second aspect of the present application includes: a first folding body 202 and a second folding body 204 rotatably connected; the display assembly 100 according to the embodiment of the first aspect is disposed on one side of the first folding body 202 and the second folding body 204.
According to the embodiment of the electronic device 200 provided by the application, the electronic device mainly includes the first folding body 202 and the second folding body 204, and the display assembly 100 is disposed on one side of the first folding body 202 and one side of the second folding body 204, so that when the first folding body 202 rotates relative to the second folding body 204, the display assembly 100 can be folded accordingly.
It should be appreciated that the display assembly 100 may be disposed on the inside or on the outside.
The first folding body 202 may be provided with a first display area 1162, and the second folding body 204 may be provided with a second display area 1164.
In addition, since the electronic device 200 includes the display assembly 100 of the above embodiment, there are advantages of the embodiments of the display assembly 100 described above.
The electronic device 200 includes a mobile phone, a tablet, a camera, a video camera, a notebook, and the like having a folding function.
Further, the flexible screen is disposed on the inner sides of the first folding body 202 and the second folding body 204, the magnetic forces of the magnetic layer 106 and the magnetic support 102 are attractive forces, and the flexible screen is disposed on the outer sides of the first folding body 202 and the second folding body 204, and the magnetic forces of the magnetic layer 106 and the magnetic support 102 are repulsive forces.
In a specific embodiment, the flexible screen is disposed on the inner sides of the two folding bodies, and the whole electronic device 200 is an inner folding screen device, and at this time, the magnetic force between the magnetic layer 106 and the magnetic support 102 should be attractive, so that the portion with the protruding crease can move towards the magnetic support 102 under the action of the attractive force, thereby realizing crease leveling.
In another specific embodiment, the flexible screen is disposed on the outer sides of the two folding bodies, and the whole electronic device 200 is an external folding screen device, and at this time, the magnetic force between the magnetic layer 106 and the magnetic support 102 should be repulsive, so that the portion with the concave crease can move away from the magnetic support 102 under the repulsive force, thereby realizing crease leveling.
The application also provides a flexible screen (i.e. the display assembly 100) of a specific embodiment, mainly starting from the crease form of the folding screen, and designing a novel crease improvement structure by combining electromagnetic force theory by using the mechanical property of the folding screen. The structure adopts an electromagnetic structure to restrain the folding screen, and does not add extra contact to the screen. The structure has the advantages that the reliability of the screen is ensured, and meanwhile, the electromagnetic parameters can be flexibly adjusted according to different mobile phone schemes, so that the structure has wide applicability.
In an ideal state, the flexible screen can be restored to an initial state after folding is completed: the layers of the flexible screen remain the original thickness and straight, however, due to the creep property of the optical cement 112 and the movement principle of the whole machine, the folded form of the folded screen cannot reach an ideal state, and after being extruded for another effect, the folded form can move to two lateral sides, and finally, the two lateral sides where folding occurs can have bulges, and the middle part of the folded form can be sunken downwards.
In order to solve the above-mentioned phenomenon, under the premise of not influencing the bending performance of the screen, the flexible screen is filled with powdery magnetic substance (i.e. the magnetic layer 106) or film magnetic substance, and the steel mesh structure (i.e. the magnetic supporting piece 102) of the screen is combined, so that attractive force is generated between the magnetic substance and the steel mesh, and the heights of the two sides are reduced, so that the folding crease of the folding screen can be effectively improved.
Wherein the powdery or film-like magnetic substance can be fixed on the folding screen by bonding or coating, and has little influence on the bending performance of the folding screen due to the low rigidity of the powdery or film-like substance.
Further, the folded screen will be folded, but magnetic force will be generated between the magnetic film layer and the steel net, and downward force will be applied to the arched portion of the screen. The highest arched parts at the two ends of the crease, so that the needed magnetic force is the largest; the folds are recessed down near the center of the fold area, so that the required attractive force is significantly reduced, so that the height of the two ends of the fold is reduced. Therefore, the magnetic powder in the part of the magnetic film corresponding to the two sides of the crease is more so as to strengthen the magnetic force; the magnetic powder at the concave part of the crease is less.
In another specific embodiment, instead of providing a powdered or film-like magnetic substance at the bottom of the flexible screen, a circular conductive wire (i.e., coil 114) is provided, and the current direction of the conductive wire and the magnetic induction direction generated by the conductive wire are as shown in the figure, and the conductive wire can be adhered to the folding screen, so that the conductive wire is not distributed in the center of the bending area, and therefore, the bending performance of the folding screen is less affected.
Those skilled in the art will appreciate that the magnetic induction of the magnetic field generated by the energized conductor at a pointCan be determined by the following formula:
wherein: mu (mu) 0 Is the permeability in vacuum; i is the current intensity in the energized conductor;the current direction of the energized wire; />Is the direction vector of the current element to a certain point; r is the distance from the current element to a certain point.
The current directions of the two groups of energized wires can be the same direction current, the ferromagnetic steel mesh (namely the magnetic support piece 102) can generate an induced magnetic field in the magnetic field of the energized wires, electromagnetic force which attracts each other is excited, and finally the energized wires can realize the application of load to the arched parts on two sides of the folding screen, thereby being beneficial to improving the arched height on two sides of the folding screen and further improving the crease.
Further, magnet materials are embedded in two sides of the stretching area of the steel mesh structure or powder magnets are used for coating, so that a magnetic field in the same direction as that of the screen magnetic film is generated, and the crease effect can be further improved.
Of course, the force of the ferromagnetic steel mesh against the coil 114 can be determined by the following equation:
wherein: i 2 Is a current element in a steel mesh; l (L) 2 Is a current path in the steel mesh.
According to the embodiment of the display assembly and the electronic equipment, under the action of the magnetic supporting piece and the magnetic layer, the magnetic force of the magnetic supporting piece and the magnetic layer can be utilized, the area with the raised crease is attached to the magnetic supporting piece as much as possible under the action of the magnetic force, so that the display assembly in the bending part can be relieved by a certain crease, and the crease formed after the display assembly is folded is improved.
