Detailed Description
In order to more clearly explain the present application, the present application is further described below with reference to the embodiments and the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not intended to limit the scope of the present application.
One of the main advantages of the flexible display module is that it can be used to manufacture foldable display devices, so that these devices have high portability, and the display area can be enlarged when the flexible display module is used, which is very scientific.
The folding display equipment that has been released in the market at present, mostly belong to small-size product, researchers discover that after the size of the folding screen increases, especially in the screen folding process, because the glue film can not release the internal stress completely, the flexible cover plate of the screen surface layer and the membrane material close to the flexible cover plate are compressed, and the flexible cover plate is easy to generate compression buckling wrinkles, thereby forming wave wrinkles at the edge of the screen, as shown in fig. 1, the reason for causing the folding screen wrinkling phenomenon lies in that along with the increase of the screen size, the length along the folding direction is increased, according to the formula of the stable euler of the unbalance of the pressure lever
As the length increases, its critical buckling load is inversely proportional to the square of the length, which means that as the length of the screen increases, the compressive buckling critical load of the film layer decreases very quickly, causing buckling instability that results in wrinkles.
In fact, the screen is subjected to other forces in addition to the buckling of the compression bar during folding, and the actual compression buckling wrinkle condition is much more complex. Referring to the euler formula, it can be seen that the production difficulty of medium-size and large-size folding is much more difficult than that of small-size products for folding screens.

For the folding display screen, when the folding display screen is folded, the lower layer structure can generate extrusion force on the upper layer structure, and because each film layer is thinner, the area of the light-emitting side surface of the folding display module, which is close to the bending axis, is easy to generate wrinkles under the action of the extrusion force. For example, as shown in fig. 3, during the folding process, the light-emitting side surface near the folding area 103 of the folded display module is pressed to bulge upward, i.e. to form a wrinkle as shown in fig. 1.
It should be noted that the folding area 103 of the folding display module is the bending area shown in fig. 3, the first planar area 101 is a left half area shown in fig. 3, and the second planar area 102 is a right half area shown in fig. 3; wherein the first planar region 101, the folding region 103 and the second planar region 102 form a flat panel display when the folding display device is in the unfolded state.

It should be noted that, as shown in fig. 5, the bezel is an annular structure, the size of the opening area in the middle of the annular structure is equivalent to the display area of the foldable display module, the bezel is disposed on the light-emitting side of the foldable display module, and the edge position (the edge of the lower surface of the inner side of the annular structure) of the bezel is fixedly connected (e.g., glued, etc.) to the cover bezel 104 on the surface of the foldable display module, so as to form the structure shown in fig. 6, wherein the first bezel 202 corresponds to the cover bezel 104 of the first planar area 101 of the foldable display module, the second bezel 203 corresponds to the cover bezel 104 of the second planar area 102 of the foldable display module, and the foldable base 30 is disposed on the non-light-emitting side of the.
It should be noted that the material of the first flexible connecting portion 201 connecting the first border 202 and the second border 203 may be a flexible material such as rubber, thermoplastic polyurethane elastomer (TPU), etc., which is beneficial for folding the border; the first flexible connecting portion 201 of pressing the frame sets up with folding district 103 of folding display module assembly relatively to make press the frame can fold along with folding display module assembly's folding, can not lead to the fact the influence to folding display module assembly's folding.
Utilize the apron frame 104 rigid coupling frame of folding display module assembly, at folding in-process, elastic element can apply the pulling force to the frame of pressing, thereby exert the pulling force to folding inside surface, with the extrusion force that alleviates folding display module assembly and received, make whole flexible display module assembly be difficult to produce the bucking fold, avoid folding display module assembly premature failure, the life of folding display module assembly has been prolonged, fold and the crease problem of folding display module assembly has been improved, user's visual effect has been guaranteed.
In some embodiments, the folding base includes a bottom plate and side plates formed by bending edges of the bottom plate, and the first ends of the first elastic element 40 and the second elastic element 50 are respectively connected to the side plates.
It should be noted that, a rotating shaft is disposed at a position of the folding base corresponding to the folding area 103 of the folding display module.
The side plates which are convenient for the connection of the elastic elements are formed by bending the edges of the folding base, so that the volume of the folding display equipment can be reduced, and the production cost is reduced.
In some embodiments, as shown in fig. 2 and 3, the cross section of the first border 202 and the cross section of the second border 203 are respectively a T-shaped structure, and respectively include a horizontal plate and a vertical plate, the bottom surface of one end of the horizontal plate of the first border 202 is fixedly connected to the cover frame 104 of the first planar area 101, the bottom surface of one end of the horizontal plate of the second border 203 is fixedly connected to the cover frame 104 of the second planar area 102, the second end of the first elastic element 40 is connected to the vertical plate of the first border 202, and the second end of the second elastic element 50 is connected to the vertical plate of the second border 203.
Therefore, the buckling wrinkle phenomenon of the folding display module can be effectively avoided in a mode that the elastic element pulls the pressing frame and then the pressing frame transmits the pulling force to the light-emitting side surface (on the cover plate, namely the upper surface shown in figures 2 and 3) of the flexible display module.
In some embodiments, the number of first elastic elements 40 and second elastic elements 50 is the same.
The same number of the first elastic elements 40 and the second elastic elements 50 can ensure that the two plane areas of the foldable display module are uniformly stressed, so that the phenomenon of buckling and folding of the foldable display module can be more effectively avoided. It should be noted that, in the embodiment, specific quantity values of the first elastic element 40 and the second elastic element 50 are not limited, the specific setting quantity may be considered as the overall size of the foldable display module, and if the size is larger, about more first elastic elements 40 and second elastic elements 50 may be set to ensure that the two planar areas are uniformly stressed respectively.
In order to better realize the uniform stress of the two plane areas of the foldable display module, in some embodiments, the first elastic element 40 and the second elastic element 50 are symmetrically arranged along the bending axis of the folding area 103.
In some embodiments, the spring constant of the first and second spring elements 40, 50 is the same.
In addition, because folding display module is lighter and thinner, the material is fragile, and is higher to the requirement of pulling force, and the fold of folding display module can't be realized flattening to the pulling force undersize, and the pulling force is too big to cause the inside interlaminar shear of folding display module and make the problem that folding display module became invalid. Accordingly, in some embodiments, the first elastic element 40 and the second elastic element 50 are each elastic elements with adjustable elastic coefficients. It should be noted that the optimum elastic modulus can be obtained through experimental tests.
From this, through adopting the elastic element of elasticity coefficient adjustable, can realize that first elastic element 40 and second elastic element 50 are adjustable to the pulling force of pressing the frame, avoid because the too little fold that can't realize leveling folding display module assembly of pulling force and the too big problem that causes shearing between folding display module assembly internal layer and make folding display module assembly inefficacy of pulling force.
Further, the first elastic member 40 and the second elastic member 50 are tension springs, respectively.
The tension spring has the advantages of simple structure, easiness in realization, reduction in production cost and the like.
In addition, traditional folding display device adopts modes such as optical cement (OCA glue) to realize being connected between each level of display device, when folding, can produce a pulling force to the underlying structure when folding display module assembly is folding, under the great condition of this pulling force, can lead to folding display module assembly to receive to pull the effect and become invalid.
If the foldable display module is directly fixed on the foldable base 30, the foldable display module may be damaged/failed by being pulled by the foldable base 30 when being folded. Therefore, in some embodiments, as shown in fig. 2, the folding display device further comprises a sliding plate comprising a first sliding plate 602 and a second sliding plate 603 connected by a second flexible connecting portion 601, the first sliding plate 602 is fixedly connected with the base plate of the first planar region 101, the second sliding plate 603 is fixedly connected with the base plate of the second planar region 102, and the first sliding plate 602 and the second sliding plate 603 are respectively slidably connected with the bottom plate of the folding base 30.
The first slide plate 602 is adhesively fixed to the non-light-emitting side (toward the folding base 30 side) of the first planar section 101, and the second slide plate 603 is adhesively fixed to the non-light-emitting side (toward the folding base 30 side) of the second planar section 102.
In a specific example, the first sliding bar 602 is projectively coincident with the first planar region 101 and the second sliding bar 603 is projectively coincident with the second planar region 102.
In a specific example, when the folding occurs, the first sliding plate 602 and the second sliding plate 603 can respectively slide on the first planar area 101 and the second planar area 102 to a direction close to the folding area 103, so as to perform path compensation on the folding display module, specifically, the first sliding plate 602 performs path compensation on the first planar area 101, and the second sliding plate 603 performs path compensation on the second planar area 102.
