[0001] This application claims priority to Chinese Patent Application No. 201911393588.0, filed with the Chinese Patent Office on December 30, 2019 and entitled "ELECTRONIC DEVICE".TECHNICAL FIELD

[0002] This application relates to the field of electronic device technologies, and in particular, to an electronic device.BACKGROUND

[0003] With gradual development of electronic device technologies, a display panel is usually disposed on an electronic device, to display text, a picture, a user interaction interface, or the like.

[0004] In related technologies, an electronic device includes a frame body and a display panel. Devices such as a battery and a circuit board are installed on an inner side of the frame body, and the display panel covers an outer side surface of the frame body. An annular adhesive ring is disposed between the display panel and the frame body. The adhesive ring is disposed close to an edge of the display panel, and the display panel may be adhered to the frame body by using the adhesive ring. The display panel is connected to the frame body by using the adhesive ring, so that a connection area can be reduced while sufficient connection force is ensured, and a connection structure between the display panel and the frame body can be also simplified.

[0005] However, in related technologies, the display panel is connected to the frame body by using the adhesive ring, and in a maintenance process of the electronic device, the display panel needs to be peeled off from the frame body. Consequently, disassembly of the display panel is relatively difficult, and the display panel is easily damaged in the disassembly process.

[0006] CN107239103A discloses a removable screen of a tablet comprising a display mounted to a shield frame by an easy-to-draw glue bond and a pulling head that passes through an opening.

[0007] CN208953991U a kind of electronic equipment comprising a shell and a display screen arranged on shell, and wherein easy-to-draw glue is set between shell and display screen and the easy-to-draw glue can fracture, the pulling portion being connected with the easy-to-draw glue and being exposed to outside the display screen.SUMMARY

[0008] The present invention is as set out in the claims.

[0009] In view of this, embodiments of this application provide an electronic device, to resolve technical problems that disassembly of a display panel is relatively difficult and the display panel is easily damaged in the disassembly process.

[0010] An embodiment of this application provides an electronic device, including a display panel, an adhesive film, and a frame body. The adhesive film is disposed between the display panel and the frame body, the adhesive film has a pulling head that extends outside the display panel and the frame body, and the adhesive film is an elastic adhesive film, or the adhesive film hardens after subjecting to tension parallel to the display panel, wherein the pulling head is disposed between a decorative sheet and the frame body. In other words, the adhesive film hardens and loses adhesion after subjecting to tension in a direction parallel to a plane on which the adhesive film is located, so that the adhesive film is separated from both the display panel and the frame body, and disassembly is easy.

[0011] In the electronic device provided in this embodiment of this application, one end of the adhesive film has the pulling head that extends outside the display panel and the frame body, and when the electronic device is maintained, the pulling head may be pulled to separate the adhesive film from the frame body and the display panel, and the adhesive film between the frame body and the display panel is gradually pulled out, so that the display panel is separated from the frame body, and the display panel is disassembled. The disassembly is relatively easy, force on the display panel is relatively small in the disassembly process, and the display panel is not damaged. In addition, the display panel is connected to the frame body by using the adhesive film, so that a part of the display panel can be prevented from being deformed by local force on the display panel.

[0012] In the electronic device, the adhesive film is in a strip shape, and the adhesive film is disposed along an edge of the display panel. A connection area between the adhesive film and each of the display panel and the frame body is reduced while a firm connection between the display panel and the frame body is ensured, thereby facilitating pulling out the adhesive film between the display panel and the frame body by using the pulling head.

[0013] In the electronic device, the electronic device further includes a decorative sheet, the decorative sheet covers an outer side surface that is of the frame body and that faces the display panel, and the decorative sheet is located at one end of the display panel. In this way, a decorative effect of the electronic device can be improved.

[0014] In the electronic device, the decorative sheet is provided with a metal layer or a coating in a specific color. In this way, the decorative effect of the electronic device can be further improved.

[0015] In the electronic device, the pulling head is disposed between the decorative sheet and the frame body. In this way, the pulling head located outside the display panel and the frame body can be prevented from affecting installation or work of another element in the electronic device.

[0016] In the electronic device, the outer side surface is provided with a groove, the pulling head is disposed in the groove, and the decorative sheet covers the groove.

[0017] In this way, when the electronic device is normally used, the decorative sheet can prevent the pulling head from protruding from the groove, so as to further prevent the pulling head located outside the display panel and the frame body from affecting installation or work of another element in the electronic device.

[0018] In the electronic device, the frame body has a decorative surface adjacent to the outer side surface, an arc-shaped chamfer is disposed at a junction of the outer side surface and the decorative surface, and the decorative sheet covers the arc-shaped chamfer.

[0019] In the electronic device, the decorative sheet includes a bent portion covering the arc-shaped chamfer and a fixed portion covering the decorative surface. In this way, the decorative effect of the electronic device can be further improved.

[0020] In the electronic device, a part of the display panel is located between the fixed portion and the arc-shaped chamfer. In this case, the bent portion of the decorative sheet can press the display panel on the arc-shaped chamfer, to prevent the display panel from being separated from the arc-shaped chamfer. In this case, the edge of the display panel is bent, so that the decorative effect of the electronic device can be further improved.

[0021] In the electronic device, the frame body is provided with an accommodation hole, and the pulling head is disposed in the accommodation hole.

[0022] In this way, the pulling head can be disposed in the accommodation hole, thereby preventing the pulling head from affecting installation or work of another element in the electronic device

[0023] In the electronic device, there are a plurality of adhesive films, the plurality of adhesive films are sequentially disposed along the edge of the display panel, each adhesive film is provided with at least one pulling head, and adjacent pulling heads are disposed in the same accommodation hole.

[0024] In this way, a quantity of holes disposed on the frame body can be reduced.

[0025] In the electronic device, the display panel covers the accommodation hole. The pulling head can be prevented from protruding from the accommodation hole during use.

[0026] In the electronic device, the frame body includes a first folding portion and a second folding portion that are rotatably connected, the display panel covers the first folding portion and the second folding portion, and an adhesive film is disposed between the display panel and both of the first folding portion and the second folding portion. The electronic device is a folding device, thereby improving user experience.

[0027] In the electronic device, the display panel includes a cover and a screen body located between the cover and the frame body, and the adhesive film is connected to the cover and the frame body, or the adhesive film is connected to the screen body and the frame body.

[0028] In this way, the adhesive film is connected to the cover or the screen body of the display panel, and when the pulling head is pulled, the adhesive film is separated from the frame body and the display panel, and the adhesive film between the frame body and the display panel is gradually pulled out, so that the display panel is separated from the frame body, and the display panel is disassembled. The disassembly is relatively easy, force on the display panel is relatively small in the disassembly process, and the display panel is not damaged.

[0029] In the electronic device, the adhesive film includes thermoplastic polyurethane rubber, or the adhesive film includes butyronitrile rubber and phenolic resin, or the adhesive film includes an easy-to-pull tape. The adhesive film has strong adhesion in a direction perpendicular to a plane on which the adhesive film is located, and has elasticity in a direction parallel to the plane on which the adhesive film is located.

[0030] Connection force between the elastic adhesive film and each of the display panel and the frame body is relatively large, and a connection area between the display panel and the frame body can be reduced while a firm connection between the frame body and the display panel is ensured. When the adhesive film is disposed between the cover and the frame body, a black edge caused by a connection between the cover and the adhesive film can be reduced. In addition, because a connection area between the cover and the adhesive film is reduced, an area of the screen body can be increased, and a screen-to-body ratio of the electronic device can be increased. When the easy-to-pull tape subjects to tension in a direction parallel to a plane on which the easy-to-pull tape is located, the easy-to-pull tape is deformed in the direction of the tension, so that the easy-to-pull tape rapidly hardens and loses adhesion, the deformed easy-to-pull tape is separated from the display panel and the frame body, and disassembly is relatively easy.BRIEF DESCRIPTION OF DRAWINGS

DESCRIPTION OF EMBODIMENTS

[0033] Terms used in implementations of this application are merely used to explain specific embodiments of this application, but are not intended to limit this application. The following describes the implementations of the embodiments of this application in detail with reference to accompanying drawings.

[0034] An embodiment of this application provides an electronic device. The electronic device includes but is not limited to a mobile or fixed terminal with a display panel, for example, a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a handheld computer, a walkie-talkie, a netbook, a POS terminal, a personal digital assistant (personal digital assistant, PDA), an event data recorder, a wearable device, and a virtual reality device.

[0035] As shown in FIG. 1, in this embodiment of this application, the electronic device may be a folding device, and a corresponding display panel 30 is a flexible display panel. For example, the display panel 30 may be an organic light-emitting diode (OLED) display panel.

[0036] A frame body 10 in the electronic device includes a first folding portion 101 and a second folding portion 102, the first folding portion 101 and the second folding portion 102 may be rotatably connected by using a rotating shaft or a hinge, and the display panel 30 covers the first folding portion 101 and the second folding portion 102. When folding is performed, the first folding portion 101 rotates relative to the second folding portion 102, and the display panel 30 bends at the same time. As shown in FIG. 1, the display panel 30 is disposed under the frame body 10, and after the electronic device is folded, the first folding portion 101 and the second folding portion 102 overlap, and the display panel 30 is exposed to the outside. Certainly, in this embodiment, the display panel 30 may also be disposed on the frame body 10, and after the electronic device is folded, the display panel 30 is located between the first folding portion 101 and the second folding portion 102.

[0037] Devices such as a circuit board and a battery may be disposed on an inner side that is of the frame body 10 and that is away from the display panel 30. For example, when the electronic device is a mobile phone, the frame body 10 may be a middle frame of the mobile phone. When the electronic device is another device, the frame body 10 may be a frame carrying the display panel 30.

[0038] As shown in FIG. 2, when the electronic device is shown as a folding device, the electronic device may include a non-bezel-less screen, a flange is disposed on an outer side surface that is of the frame body 10 and that faces the display panel 30, and the flange is disposed around the display panel 30. FIG. 4 may be a cutaway drawing in an A-A direction in FIG. 2. As shown in FIG. 4, the display panel 30 is connected to the frame body 10 by using an adhesive film 20, and the adhesive film 20 may be disposed along an edge of the display panel 30, to connect the display panel 30 to the frame body 10. The display panel 30 may include a screen body 302 and a cover 301 covering the screen body 302, and the cover 301 is connected to the screen body 302. The adhesive film 20 may be disposed between the screen body 302 and the frame body 10, to implement a connection between the screen body 302 and the frame body 10. FIG. 5 may also be a cutaway drawing in the A-A direction in FIG. 2. As shown in FIG. 5, the adhesive film 20 may be further disposed between the cover 301 and the frame body 10. A projection area of the corresponding cover 301 on the frame body 10 is greater than a projection area of the screen body 302 on the frame body 10. An installation groove is disposed on the outer side surface of the frame body 10, and the screen body 302 is accommodated in the installation groove. The adhesive film 20 is disposed outside the installation groove and between the frame body 10 and the cover 301, to implement a connection between the cover 301 and the frame body 10, and the cover 301 may confine the screen body 302 in the installation groove.

[0039] As shown in FIG. 3, the electronic device may alternatively be a device with a bezel-less screen. A projection of the display panel 30 on the frame body 10 overlaps with the outer side surface that is of the frame body 10 and that faces the display panel 30. The bezel-less screen can increase a screen-to-body ratio of the electronic device. FIG. 6 may be a cutaway drawing in a B-B direction in FIG. 3. As shown in FIG. 6, projections, on the frame body 10, of the cover 301 and the screen body 302 in the display panel 30 overlap. Alternatively, FIG. 7 may also be a cutaway drawing in the B-B direction in FIG. 3. As shown in FIG. 7, a projection, on the frame body 10, of the screen body 302 in the display panel 30 is located inside a projection of the cover 301 on the frame body 10.

[0040] As shown in FIG. 8, the adhesive film 20 is disposed along an edge of the display panel 30, the adhesive film 20 is in a strip shape, and one end of the adhesive film 20 has a pulling head 201 that extends outside the display panel 30 and the frame body 10. When the electronic device is maintained, the adhesive film 20 may be separated from the frame body 10 and the display panel 30 by pulling the pulling head 201, and the adhesive film 20 between the frame body 10 and the display panel 30 is gradually pulled out, so that the display panel 30 is separated from the frame body 10, and the display panel 30 is disassembled. The disassembly is relatively easy, force on the display panel 30 is relatively small in the disassembly process, and the display panel 30 is not damaged. In addition, the display panel 30 is connected to the first folding portion 101 and the second folding portion 102 by using the adhesive film 20. Compared with a fact in which the display panel 30 is connected to the first folding portion 101 and the second folding portion 102 by using glue, a part of the display panel 30 can be prevented from being deformed by local force on the display panel 30.

[0041] In this embodiment, the adhesive film 20 is in the strip shape, so that a connection area between the adhesive film 20 and each of the display panel 30 and the frame body 10 can be reduced while a firm connection between the display panel 30 and the frame body 10 is ensured, thereby facilitating pulling out the adhesive film 20 between the display panel 30 and the frame body 10 by using the pulling head 201.

[0042] When the display panel 30 is disassembled, a direction of pulling the pulling head 201 may be shown by a dashed line in FIG. 9, and the pulling head 201 is pulled from a direction parallel to the display panel 30 to a direction away from the display panel 30 (to be specific, to the outside of the electronic device), so that a part of the adhesive film 20 is pulled out, and then remaining adhesive film 20 is sequentially pulled out along a direction surround the display panel 30, thereby separating the display panel 30 from the frame body 10. It should be noted that the adhesive film 20 needs to have sufficient strength in the direction parallel to the display panel 30, to prevent the adhesive film from breaking when the pulling head 201 is being pulled.

[0043] In an implementation, the adhesive film 20 may be an elastic adhesive film, and the elastic adhesive film mainly includes thermoplastic polyurethane (Thermoplastic polyurethanes, TPU for short) rubber, or mainly includes butyronitrile rubber and phenolic resin. In this way, the elastic adhesive film has strong adhesion in a direction perpendicular to a plane on which the elastic adhesive film is located, to ensure sufficient connection force between the display panel 30 and the frame body 10. The elastic adhesive film has specified elasticity in a direction parallel to the plane on which the elastic adhesive film is located, and when the pulling head 201 of the adhesive film is pulled, force is locally applied to a junction of the elastic adhesive film and the pulling head 201, so that the elastic adhesive film is separated from the display panel 30 and the frame body 10. Then, the pulling head 201 continues to be pulled, and the elastic adhesive film between the display panel 30 and the frame body 10 may be gradually pulled out, so that the display panel 30 is separated from the frame body 10.

[0044] Further, since connection force between the elastic adhesive film and each of the display panel 30 and the frame body 10 is relatively large, a connection area between the display panel 30 and the frame body 10 can be reduced while a firm connection between the frame body 10 and the display panel 30 is ensured. Still referring to FIG. 5 and FIG. 7, when the adhesive film 30 is disposed between the cover 301 and the frame body 10, a black edge caused by a connection between the cover 301 and the adhesive film 20 can be reduced. In addition, because a connection area between the cover 301 and the adhesive film 20 is reduced, an area of the screen body 302 can be increased, and a screen-to-body ratio of the electronic device can be increased.

[0045] In another implementation, the adhesive film 20 may alternatively be an easy-to-pull tape mainly including a material based on rubber, polyurethane, or the like. The easy-to-pull tape has specified adhesion in a direction perpendicular to a plane on which the easy-to-pull tape is located, and the display panel 30 may be adhered to the frame body 10. When the pulling head 201 is pulled, the easy-to-pull tape subjects tension in a direction parallel to the plane on which the easy-to-pull tape is located, the easy-to-pull tape is deformed in the direction of the tension, so that the easy-to-pull tape rapidly hardens and loses adhesion, and the deformed easy-to-pull tape is separated from the display panel 30 and the frame body 10. Then, the pulling head 201 continues to be pulled, and the easy-to-pull tape between the display panel 30 and the frame body 10 is gradually pulled out, so that the display panel 30 is separated from the frame body 10.

[0046] In this embodiment, there may be a plurality of extension shapes of the adhesive film 20 in the strip shape may extend between the display panel 30 and both of the first folding portion 101 and the second folding portion 102 in a plurality of shapes. For example, as shown in FIG. 8, the adhesive film 20 may extend between the display panel 30 and both of the first folding portion 101 and the second folding portion 102 in a shape of a straight line, and the pulling head 201 may be disposed at either end of the adhesive film 20 in an extension direction, or pulling heads 201 are disposed at both ends of the adhesive film 20 in the extension direction. When the pulling heads 201 are disposed at both ends of the adhesive film 20 in the extension direction, the adhesive film 20 between the display panel 30 and the frame body 10 may be pulled out by pulling either of the pulling heads 201, thereby disassembling the display panel 30. In addition, the pulling heads 201 are disposed at both ends of the adhesive film 20 in the extending direction, so that the display panel 30 may be further prevented from being unable to be disassembled when one pulling head 201 is damaged. Certainly, the adhesive film 20 may further extend in a curved shape between the display panel 30 and each of the first folding portion 101 and the second folding portion 102, and an area of the adhesive film 20 between the display panel 30 and each of the first folding portion 101 and the second folding portion 102 may be increased, thereby improving connection force between the display panel 30 and each of the first folding portion 101 and the second folding portion 102.

[0047] In this embodiment, still referring to FIG. 8. the adhesive film 20 may be continuously disposed between the display panel 30 and each of the first folding portion 101 and the second folding portion 102. Certainly, the adhesive film 20 may also be discontinuously disposed between the display panel 30 and each of the first folding portion 101 and the second folding portion 10210. For example, as shown in FIG. 10, the adhesive film 20 includes a first adhesive film 202 and a second adhesive film 204. The first adhesive film 202 is disposed between the first folding portion 101 and the display panel 30, and the second adhesive film 204 is disposed between the second folding portion 102 and the display panel 30. Corresponding pulling heads 201 include a first pulling head 203 disposed at one end of the first adhesive film 202 and a second pulling head 205 disposed at one end of the second adhesive film 204. During disassembly, the first pulling head 203 is first pulled to pull out the first adhesive film 202 between the first folding portion 101 and the display panel 30, and then the second pulling head 205 is pulled to pull out the second adhesive film 204 between the second folding portion 102 and the display panel 30, so as to separate that display panel 30 from the frame body 10.

[0048] As shown in FIG. 11, in this embodiment, there may be a plurality of first adhesive films 202 disposed between the first folding portion 101 and the display panel 30, and each first adhesive film 20 is provided with a first pulling head 203 that extends outside the first folding portion 101 and the display panel 30. There may be a plurality of second adhesive films 204 disposed between the second folding portion 102 and the display panel 30, and each second adhesive film 204 is provided with a second pulling head 205 that extends outside the second folding portion 102 and the display panel 30. During disassembly, the first pulling heads 203 may be sequentially pulled to pull out the first adhesive films 202 between the first folding portion 101 and the display panel 30, so as to separate the display panel 30 from the first folding portion 101. Then, the second pulling heads 205 are sequentially pulled to pull out the second adhesive films 204 between the second folding portion 102 and the display panel 30, so as to separate the display panel 30 from the second folding portion 102, thereby disassembling the display panel 30.

[0049] Based on the embodiment in which the electronic device is a folding device, the electronic device may further include a decorative sheet 40. The decorative sheet 40 is disposed on the first folding portion 101 and / or the second folding portion 102, to improve a decorative effect of the electronic device.

[0050] As shown in FIG. 12, the decorative sheet 40 includes a bent portion 401, an arc-shaped chamfer 103 is disposed at a junction of an outer side surface that is of the first folding portion 101 and that faces the display panel 30 and a decorative surface that is adjacent to the outer side surface on the first folding portion 101, and the bent portion 401 covers the arc-shaped chamfer 103. The pulling head 201 of the adhesive film is sandwiched between the arc-shaped chamfer 103 and the bent portion 401. In this way, the pulling head 201 located outside the display panel 30 and the first folding portion 101 may be prevented from affecting installation or work of another element in the electronic device. In addition, the decorative sheet 40 covers the first folding portion 101, so that the decorative effect of the electronic device is improved.

[0051] Further, the decorative sheet may further include a fixed portion 402. The bent portion 401 of the decorative sheet 40 covers the arc-shaped chamfer 103, and the fixed portion 402 of the decorative sheet 40 covers the decorative surface, so as to further improve the decorative effect of the electronic device. It should be noted that a color of the decorative sheet 40 may be the same as or different from a color of the first folding portion 101, and an example decorative sheet 40 may be red, green, blue, or the like. Certainly, a decorative layer may also be disposed on a side surface that is of the decorative sheet 40 and that is away from the first folding portion 101. The decorative layer may be a metal layer or a coating in a specific color, so as to improve the decorative effect of the decorative sheet 40.

[0052] Further, the display panel 30 may extend toward the decorative surface, and a part of the display panel 30 also covers the arc-shaped chamfer 103. In this case, the bent portion 401 of the decorative sheet 40 may press the display panel 30 on the arc-shaped chamfer 103, thereby preventing the display panel 30 from being separated from the arc-shaped chamfer 103.
