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.

Along with the continuous development of flexible display screen technique, current electronic equipment begins to carry on flexible display screen gradually, the electronic equipment who carries on flexible display screen can fold the use and also can expand the use when using, because the material of flexible display screen can take place the creep at folding in-process, wherein, the creep means the material under the unchangeable condition of keeping using, the strain increases along with the extension of time, in the in-process that flexible display screen is in static buckling (flexible display screen keeps fold condition), because the material of flexible display screen takes place the creep, lead to the surface of flexible display screen to appear the crease. For example: fig. 1 shows a flexible display screen 10 used for a period of time, and the flexible display screen 10 is subjected to more inward folding operations, wherein an inner surface 1 is used for installing a middle frame laid on an electronic device, and an outer surface 2 is used for exposed operations. When the flexible display screen 10 is folded inwards, the inner surface 1 of the flexible display screen 10 in the folding area is stretched to deform and arch, the outer surface 2 is extruded to form a recess, and after being folded for multiple times, the surface of the flexible display screen 10 generates creases. For another example, fig. 2 shows another flexible display 10 after being used for a period of time, the flexible display 10 is subjected to a relatively large folding operation, during the folding operation, the inner surface 1 is pressed to deform and generate a depression, the outer surface 2 is stretched to deform and generate an arch, and after being folded for many times, the surface of the flexible display 10 generates a crease. Therefore, the inventor proposes the flexible display module and the electronic device in the embodiment of the application. Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Examples

Referring to fig. 3, the present embodiment provides a flexible display module 100, which can be applied to the electronic device 200 shown in fig. 10, wherein the flexible display module 100 includes a display module 120 and a back film layer 110, and the display module 120 is disposed on a surface of the back film layer 110.

In the present embodiment, the back film layer 110 may be made of a flexible material, for example, a polyimide film (PI film), a polyester film (BOPET film), a cyclic olefin polymer film (COP film), a polydimethylsiloxane film (PDMS film), and the like. The back film layer 110 has a first surface 111 and a second surface 112 facing away from each other, wherein the first surface 111 and the second surface 112 are disposed along a thickness direction of the back film layer 110. The back film layer 110 can be used to protect the display module 120 and prevent the display module 120 from being damaged, such as stabbing, scratching, or rubbing the display module 120.

Referring to fig. 3 again, in the embodiment, the display module 120 is disposed on the first surface 111 of the back film layer 110, and the display module 120 includes a display layer 123, a polarizing layer 121, and a flexible glass layer 122, wherein the display layer 123, the polarizing layer 121, and the flexible glass layer 122 are stacked. The display layer 123 is for image display, and the display layer 123 may be an OLED (organic light emitting diode); the polarizing layer 121 is used for filtering light generated by the display layer 123, and the polarizing layer 121 and the display layer 123 together play a role of development. The polarizing layer 121 may be an optical film with a function of generating polarized light, which is formed by compounding multiple layers of polymer materials; the flexible glass layer 122 may be made of a transparent flexible glass material.

The display layer 123, the polarizing layer 121, and the flexible glass layer 122 are stacked, which means that the display layer 123, the polarizing layer 121, and the flexible glass layer 122 are stacked. It is understood that the display layer 123, the polarizing layer 121 and the flexible glass layer 122 are stacked here, and it is not specifically meant that the display layer 123, the polarizing layer 121 and the flexible glass layer 122 are stacked in sequence.

The flexible glass layer 122 does not creep and fatigue during the folding process, and after being folded for multiple times, the surface of the flexible glass layer 122 can still be kept flat and does not generate creases, so that the flexible glass layer 122 can be used for supporting other parts of the flexible display module 100.

It is understood that the position of the flexible glass layer 122 can be adjusted according to actual requirements. In some embodiments, flexible glass layer 122 may be disposed adjacent to display layer 123. For example: as an embodiment, referring to fig. 4, the display layer 123 has a display surface 1231 and a display back surface 1232 facing away from each other. The display layer 123 may be disposed on the first surface 111 of the back film layer 110, that is, the display back surface 1232 is disposed on the first surface 111 of the back film layer 110, and may be adhered to the back film layer 110 by an adhesive. The flexible glass layer 122 is disposed on the surface of the display layer 123 far from the back film layer 110, that is, the flexible glass layer 122 is disposed on the display surface 1231 and can be bonded to the display layer 123 through an adhesive; the polarizing layer 121 is disposed on a surface of the flexible glass layer 122 far from the display layer 123, and can be adhered to the flexible glass layer 122 through an adhesive, where the adhesive may be a pressure-sensitive adhesive, an optical transparent adhesive, or other transparent adhesive.

When the display layer 123 is bent statically (the display layer 123 is kept in a folded state) or folded, the display layer 123 creeps, so that a surface of the display layer 123 may be creased, and in some application environments, as shown in fig. 4, when the display layer 123 is folded inwards, a portion of the display surface 1231 of the display layer 123 in the folded region is squeezed to be deformed, so as to generate a recess; the portion of the display back 1232 of the display layer 123 in the folding region may be stretched to deform and arch, and after being folded for a plurality of times, the display surface 1231 and the display back 1232 deform differently, which results in a deformation difference on the two side surfaces of the display layer 123, and further may generate a crease on the surface of the display layer 123.

By arranging the flexible glass layer 122 between the display layer 123 and the polarizing layer 121, after the flexible glass layer 122 is folded for multiple times, the surface of the flexible glass layer 122 can still be kept flat, and can always provide support for the display layer 123 and the polarizing layer 121, and the flexible glass layer 122 can pull the display surface 1231 of the display layer 123, so that the concave part of the display surface 1231 is restored to the original flat state under the action of a pulling force, meanwhile, the flexible glass layer 122 pulls the display back surface 1232 through the display layer 1231, so that the arched part of the display back surface 1232 is restored to the original flat state under the action of the pulling force, and the display layer 123 is prevented from generating creases; accordingly, the flexible glass layer 122 can support the recessed portion of the polarizing layer 121, so that the recessed portion of the polarizing layer 121 can be restored to an original flat state under the supporting force, and the occurrence of creases in the polarizing layer 121 can be reduced.

In addition, flexible glass layer 122 and display layer 123 are located adjacent position, and display layer 123 is at the folding in-process, and the deformation recovery performance of flexible glass layer 122 can directly act on display layer 123, further improves display layer 123 and resumes deformation at the folding in-process, keeps smooth ability.

In some application environments, as shown in fig. 5, when the display layer 123 is folded outward, a portion of the display surface 1231 of the display layer 123 in the folding area may be stretched and deformed to be arched; the part of the display back 1232 of the display layer 123, which is located in the folding area, is squeezed to deform and generate a recess, after being folded for many times, the surface of the flexible glass layer 122 can still be kept flat and can always provide support for the display layer 123, and the flexible glass layer 122 can support the part of the display surface 1231 of the display layer 123, so that the arched part of the display surface 1231 is restored to the original flat state under the action of the supporting force, and meanwhile, the flexible glass layer 122 supports the part of the display back 1232, which is recessed, so that the arched part of the display back 1232 is restored to the original flat state under the action of the supporting force, thereby preventing the display layer 123 from generating a crease; correspondingly, the flexible glass layer 122 can pull the arched part of the polarizing layer 121, so that the polarizing layer 121 is restored to the original flat state under the action of the pulling force, and the generation of creases in the polarizing layer 121 is reduced.

As an embodiment, as shown in fig. 6, the flexible glass layer 122 may be disposed on the first surface 111 of the back film layer 110, the display layer 123 is disposed on a surface of the flexible glass layer 122 away from the back film layer 110, and the polarization layer 121 is disposed on a surface of the display layer 123 away from the flexible glass layer 122, that is, the polarization layer 121 is disposed on the first surface 1231 of the display layer 123.

By disposing the display layer 123 on the flexible glass layer 122, the display layer 123 can be disposed on the flexible glass layer 122 more smoothly because the surface of the flexible glass layer 122 is flat and does not generate creases. When the display surface 1231 of the display layer 123 is depressed, the display back surface 1232 is raised, and the flexible glass layer 122 supports the portion of the display back surface 1232 that is raised, so that the portion of the display back surface 1232 that is raised is supported by the supporting force to return to the original flat state, and at the same time, the flexible glass layer 122 supports the portion of the display back surface 123 that is depressed by the display back surface 1232, so that the portion of the display back surface 123 that is depressed is returned to the flat state by the supporting force. Correspondingly, when the display surface 1231 is arched and the display back surface 1232 is sunken, the flexible glass layer 122 is pulled to the part of the display back surface 1232 where the sunken part is formed, and simultaneously, the part of the display back surface 1232 where the arched part is formed is pulled to the display surface 1231, so that the display surface 1231 and the display back surface 1232 are simultaneously pulled to the flexible glass layer 122 and return to the original flat state, and meanwhile, through the acting force between the layers, the deformation restoring force of the flexible glass layer 122 can be transmitted to the polarizing layer 121 and the back film layer 110, and the polarizing layer 121 and the back film layer 110 can be prevented from generating creases.

As an embodiment, as shown in fig. 7, the display layer 123 may be disposed on the surface of the backing layer 110, the polarizing layer 121 is disposed on the surface of the display layer 123 far from the backing layer 110, that is, the polarizing layer 121 is disposed on the display surface 1231 of the display layer 123, and the flexible glass layer 122 may be disposed on the surface of the polarizing layer 121 far from the display layer 123.

By arranging the flexible glass layer 122 on the polarizing layer 121, and positioning the polarizing layer 121 and the flexible glass layer 122 at adjacent positions, for example, when the display layer 123 is folded inwards, the deformation recovery performance of the flexible glass layer 122 is acted on the display layer 123 through the polarizing layer 121, so that the flexible glass layer 122 pulls the display surface 1231 of the display layer 123, the concave part of the display surface 1231 is recovered to the original flat state under the action of a pulling force, and meanwhile, the display surface 1231 pulls the arched part of the display back surface 1232, so that the arched part of the display back surface 1232 is recovered to the original flat state under the action of the pulling force, and the display layer 123 is prevented from generating creases; for example, when the display layer 123 is folded outward, the deformation recovery performance of the flexible glass layer 122 acts on the display layer 123 through the polarizing layer 121, the flexible glass layer 122 supports the portion of the display surface 1231 of the display layer, so that the portion of the display surface 1231 that is arched is restored to the original flat state by the supporting force, and at the same time, the portion of the display back surface 1232 that is arched is supported by the display surface 11231, so that the portion of the display back surface 1232 that is arched is supported. Likewise, the flexible glass layer 122 can always provide support for the polarizing layer 121, and prevent the polarizing layer 121 from being folded.

In some embodiments, as shown in fig. 8, the flexible glass layer 122 may include a flexible glass body 1221 and a transparent buffer 1222, wherein the transparent buffer 1222 may be made of a material that is transparent and has a certain deformation function. The transparent buffer 1222 is connected to the edge of the flexible glass body 1221.

As an example, the transparent buffer 1222 includes a first transparent buffer 12221 and a second transparent buffer 12222, and the first transparent buffer 12221 and the second transparent buffer 12222 are oppositely disposed and are connected to an edge of the flexible glass body 1221.

In the process of assembling and applying to the electronic device, the transparent buffer part 122 can be connected to the housing of the electronic device, and by means of the acting force between the housing and the transparent buffer part 1222, the recovery deformability of the flexible glass layer 122 is further improved, for example, after being folded, the transparent buffer part 1222 can pull the flexible glass body 1221, because the flexible glass body 1221 can receive the transverse acting force, the surface of the flexible glass body 1221 is pulled to be more flat, and meanwhile, the display back surface 1232 receives the transverse acting force of the flexible glass body 1221, so that the surface of the glass body 1221 is more flat under the action of the pulling force.

since the flexible display module 100 is mostly folded along its length when in use, in some embodiments, the first transparent buffer portion 12221 and the second transparent buffer portion 12222 may be disposed along a length direction of the flexible glass body 1221, specifically, the flexible glass body 1221 includes a first end portion 12211 and a second end portion 12212 opposite to each other, where the first end portion 12211 and the second end portion 12212 are respectively located at two ends of the flexible glass body 1221 in the length direction, it should be noted that: the length direction refers to a direction in which the flexible glass body 1221 is folded in half during the folding process, the first transparent buffer portion 12221 is connected to the first end portion 12211, and the second transparent buffer portions 12222 are respectively connected to the second end portions 12212.

After folding, because first transparent buffer 12221 and second transparent buffer 12222 set up respectively in the both ends of flexible glass body 1221, first transparent buffer 12221 and second transparent buffer 12222 can drag the both ends of flexible glass body 1221 simultaneously, the surface of flexible glass body 1221 receives the effort of two opposite directions, make the surface of flexible glass body 1221 receive to drag and become more level and more smooth, further avoid display layer 123 and polarisation layer 121 to produce the crease. It is understood that the flexible glass layer 122 may also be made entirely of flexible glass.

As an example, as shown in fig. 9, the flexible glass layer 122 may include a first flexible glass layer 1223 and a second flexible glass layer 1224, the first flexible glass layer 1223 is disposed on a surface of the backing film layer 110, the display back surface 1232 of the display layer 123 is disposed on a surface of the first flexible glass layer 1223 away from the backing film layer 110, the second flexible glass layer 1224 is disposed on the display surface 1231 of the display layer 123 away from the first flexible glass layer 1223, and the polarizing layer 121 is disposed on a surface of the second flexible glass layer 1224 away from the display layer 123.

The benefits of this arrangement: through setting up the display layer 123 between first flexible glass layer 1223 and second flexible glass layer 1224, further avoid flexible display module assembly 100 to produce the crease, for example when display module assembly 120 infolding, the folding part of the display face 1231 of display layer 123 takes place to deform and produces sunkenly, the folding part of the display back 1232 takes place to deform and produces the hunch, at this moment, take place the part of hunch through first flexible glass layer 1223 to the display back 1232 and form the support, simultaneously, take place sunken part to drag through second flexible glass layer 1223 to the display face 1232 of display face 123, first flexible glass layer 1223 and second flexible glass layer 1224 can support or drag two surfaces of display layer 123 simultaneously, the effectual surface that avoids display layer 123 produces the crease. Meanwhile, in the process of folding, the folded portion of the surface of the polarizing layer 121 close to the second flexible glass layer 1224 deforms to generate arching, and the second flexible glass layer 1224 supports the folded portion of the surface of the polarizing layer 121 close to the second flexible glass layer 1224, so that the arched portion of the polarizing layer 121 is restored to an original flat state under the action of supporting force, and the surface of the polarizing layer 121 is prevented from generating creases.

Referring to fig. 3 again, in the present embodiment, the flexible display module 100 may further include a touch layer 130, the touch layer 130 is used for a user to perform a touch operation, the touch layer 130 is disposed on a surface of the display module 120 away from the back film layer 110, and the touch layer 130 may be adhered to the surface of the display module 120 by an adhesive, wherein the adhesive may be a transparent adhesive such as a pressure sensitive adhesive, an optical transparent adhesive, and the like. The touch layer 130 is disposed to enable the flexible display module 100 to have both touch and display functions.

specifically, in the present embodiment, the touch layer 130 is disposed on the surface of the polarizing layer 121 far away from the flexible glass layer 122. The touch layer 130 is disposed on the surface of the display module 120 away from the back film layer 110, so that the touch layer 130 can more sensitively detect an action triggered by the outside.

After folding, the deformation recovery performance of the flexible glass layer 122 can be transmitted between layers and simultaneously acts on the touch layer 130, and the flexible glass layer 122 can also support the touch layer 130, so that creases generated after the touch layer 130 is folded are avoided.

The touch layer 130 can also be disposed at other positions, for example, in some embodiments, the display layer 123 is disposed on the first surface 111 of the back film layer 110, the polarizing layer 121 is disposed on a surface of the display layer 123 away from the back film layer 110, the flexible glass layer 122 is disposed on a surface of the polarizing layer 121 away from the back film layer 110, and the touch layer 130 can be disposed on a surface of the flexible glass layer 122 away from the polarizing layer 121.

The flexible display module 100 provided in this embodiment, because the flexible glass layer 122 can not take place fatigue and creep, after folding many times, the surface of flexible glass layer 122 can still keep leveling, maintains the planarization of whole flexible display screen module 100 through setting up flexible glass layer 122 to avoid flexible display module 100 to produce the crease.

Referring to fig. 10, an electronic device 200 is further provided in the present embodiment, which includes a housing 210 and the flexible display module 100, wherein the flexible display module 100 is mounted on the housing 210.

In this embodiment, the second middle frame 212 includes a second mount 2123 and a second bezel 2124, and the second mount 2123 has a substantially plate-like structure. The second mount 2123 has a second mounting surface 21231, i.e., the surface of the second mount 2123 on the third side 2121. The second frame 2124 surrounds an edge of the second mounting member 2123.

In this embodiment, the rotating connector 213 is rotatably connected to the first middle frame 211 and the second middle frame 212, and is used for realizing the relative rotation between the first middle frame 211 and the second middle frame 212. The first middle frame 211 and the second middle frame 212 can rotate relatively by using the rotation connector 213 as a rotation axis. Wherein the rotation connector 213 may be configured as a hinge type rotation shaft, an elastic member, or other rotation shaft structure.

During rotation, the first middle frame 211 and the second middle frame 212 can be selectively folded or unfolded relatively, and in some embodiments, a rotation inclination angle of 0 to 360 ° can be formed between the first middle frame 211 and the second middle frame 212, and it is understood that the rotation inclination angle refers to an angle formed by the first mounting surface 21131 and the second mounting surface 21231.

In addition, different deformation amounts of the flexible display module 100 in the first middle frame 211 and the second middle frame 212 can be adapted to be generated, for example, when the first middle frame 211 is kept still, the second middle frame 212 rotates relative to the first middle frame 211, and since the bending deformation of the flexible display module 100 in the second middle frame 212 is larger than the bending deformation of the flexible display module 100 in the first middle frame 211, that is, the flexible display module 100 can slide relative to the housing 200 through the foam layers 220 respectively disposed on the first mounting surface 21131 and the second mounting surface 21231.

In some embodiments, the housing 210 may further include a decorative cover (not shown), wherein the decorative cover may be used to cover the edge of the flexible display module 100 for decoration and aesthetic purposes. Meanwhile, the electronic device 200 can be prevented from directly colliding with the ground in the falling process, and damage is avoided. The decorative cover is installed on the housing 60 and is located at the same side of the flexible display module 100.

in some embodiments, the electronic device 200 may further include a flexible cover (not shown), wherein the flexible cover is disposed on a surface of the display module 120 away from the back film layer 110. The flexible cover plate 40 and the display module 120 may be adhered by an adhesive, wherein the adhesive may be a pressure sensitive adhesive, an optical transparent adhesive, or other transparent adhesive. The flexible cover plate can be used for protecting the display module 120, and can prevent the display module from being scratched or damaged. Wherein, the flexible cover plate can be made of materials with flexible functions, such as: plastic film or bendable glass and the like.

The electronic device 200 provided in this embodiment can avoid the folding mark generated after the sub-device 200 is folded by adding the flexible glass layer 122 in the flexible display module 100, so that the flexible display module 100 can still keep flat after being folded many times, and the use performance of the electronic device 200 is improved.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
