It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic structural diagram of an embodiment of an electronic device provided in the present application, and fig. 2 is a schematic exploded structural diagram of the electronic device in fig. 1.

In the embodiment of the present application, the electronic device 10 may be a portable device such as a mobile phone, a tablet computer, a notebook computer, and a wearable device. In the embodiment of the present application, the electronic device 10 is taken as a mobile phone for exemplary description.

As shown in fig. 2, the electronic device 10 may include a display module 11, a rear cover 12, and a middle frame 13. The display module 11 and the rear cover plate 12 are respectively connected with the middle frame 13, so that the display module 11 and the rear cover plate 12 can form a basic structure for clamping the middle frame 13 together after the three are assembled, as shown in fig. 1. For example: the display module 11 and the rear cover plate 12 are respectively covered on two opposite surfaces of the middle frame 13 through one or a combination of assembling modes such as clamping, gluing, welding and the like. Further, a cavity structure with a certain volume can be formed after the display module 11, the rear cover plate 12 and the middle frame 13 are assembled, and the cavity structure can accommodate structural members such as a battery, a main board, a camera module, a fingerprint module, an antenna module and the like, so that the electronic device 10 can realize corresponding functions.

The display module 11 may be a screen such as an lcd (liquid Crystal display), an OLED (Organic Light-Emitting Diode), a Mini-LED, or a Micro-LED. In the embodiment of the present application, the display module 11 is taken as an OLED screen for an exemplary description.

In some embodiments, as shown in fig. 2, the display module 11 may include a transparent cover 111 and a display panel 112. After the display module 11 is assembled with the middle frame 13, the transparent cover 111 is far away from the middle frame 13 compared to the display panel 112, that is, the transparent cover 111 can be used as an outer surface of the electronic device 10. The transparent cover 111 is mainly used for protecting the display panel 112, and may be an outer surface of the electronic device 10, so as to facilitate a user to perform a touch operation such as clicking, sliding, pressing, and the like. The transparent cover 111 may be made of a rigid material such as glass, or may be made of a flexible material such as Polyimide (PI) or Colorless Polyimide (CPI). The display panel 112 is mainly used for displaying a screen, and can be used as an interactive interface to instruct a user to perform the touch operation on the transparent cover 111. The display panel 112 may be attached to the transparent cover 111 by using a sealant such as OCA (optical Clear Adhesive) or PSA (Pressure Sensitive Adhesive).

In some other embodiments, the outer surface of the electronic device 10 (i.e., the outer surface of the transparent cover plate 111) may be further provided with any one of other functional film layers, such as a tempered film, a frosted film, a decoration film, a peep-proof film, a water condensation film, and the like, so that the electronic device 10 can provide different use effects for users.

The rear cover 12 is a battery cover of the electronic device 10, and has a certain structural strength, and is mainly used to protect the electronic device 10 together with the transparent cover 111. The material of the back cover plate 12 may be rigid material such as glass, metal, rigid plastic, etc., or may be made of other electrochromic materials. Correspondingly, center 13 also has certain structural strength, is mainly used for the installation, fixes above-mentioned structure such as battery, mainboard, fingerprint module, camera module, antenna module. The material of the middle frame 13 may be rigid material such as glass, metal, rigid plastic, etc. Further, since the rear cover plate 12 and the middle frame 13 are generally directly exposed to the external environment, the rear cover plate 12 and the middle frame 13 may preferably have certain wear-resistant, corrosion-resistant, scratch-resistant, and other properties, or the outer surfaces of the rear cover plate 12 and the middle frame 13 (i.e., the outer surfaces of the electronic device 10) may be coated with a layer of functional material for wear-resistant, corrosion-resistant, scratch-resistant.

In some embodiments, the rear cover plate 12 and the middle frame 13 may be two separate structural members, as shown in fig. 1, and they may be assembled by one or a combination of clamping, gluing, welding, and the like. In other embodiments, the rear cover plate 12 and the middle frame 13 may also be integrally formed structural members, for example, by heat absorption, stamping, injection molding, and the like.

Generally, the electronic device 10 may have a box-like appearance structure as a whole, that is, the display module 11, the rear cover 12 and the middle frame 13 may have a rectangular structure. Wherein, the display module 11 has four side edges, the back cover plate 12 also has four side edges, and the middle frame 13 also has four side edges correspondingly. Arc transition is generally adopted between two side edges of the display module 11, between two side edges of the rear cover plate 12 and between two side edges of the middle frame 13, so as to increase the aesthetic appearance and the holding hand feeling of the electronic device 10. Further, at least one of the four side edges of the display module 11 may be bent toward the middle frame 13, so that the picture displayed by the display module 11 can extend from the front surface of the display module 11 to the side surface thereof in a form similar to a "waterfall". Accordingly, at least one of the four side edges of the rear cover 12 may be bent toward the middle frame 13 to enhance the aesthetic appearance and the grip feeling of the rear cover 12.

It should be noted that the side edges in the embodiment of the present application are a simple expression, and the width of the side edges is not considered, and the dimensions of the display module 11, the rear cover 12 and the middle frame 13 in the thickness direction of the electronic device 10 are not considered.

In some embodiments, the four side edges of the display module 11 and the four side edges of the rear cover 12 may be curved toward the middle frame 13, as shown in fig. 1 and 2, that is, the side edges may be curved. So set up, not only can reduce or even hide the black border width of display module assembly 11 to make electronic equipment 10 can provide bigger demonstration field of vision for the user, can also make display module assembly 11 build a visual effect around the demonstration, thereby make electronic equipment 10 bring one kind and be different from bang screen, water droplet screen, dig the hole screen, over-and-under type camera, the flat full-face screen's such as sliding closure type camera visual experience for the user, and then increase electronic equipment 10's competitiveness. In other embodiments, the display module 11 and the rear cover 12 may also be in a single-curved, double-curved, or triple-curved configuration.

In the embodiment of the present application, the electronic device 10 is exemplarily illustrated by taking a structure in which the display module 11 and the rear cover 12 are all four-sided curved as an example. The electronic device 10 shown in fig. 1 and 2 only describes a portion (e.g., one quarter) of the display module 11, the rear cover 12 and the middle frame 13, and the structures of other portions are the same as or similar to those in the drawings, and are not repeated herein. The specific structure of this quarter of the electronic device 10 is described in detail below.

With continued reference to fig. 1 and 2, the transparent cover 111 may include a first straight portion 1111 and a first curved portion 1112, and the first curved portion 1112 is connected to the first straight portion 1111 and has a smooth transition therebetween. The first bending portion 1112 is bent toward the middle frame 13, so that the edge region of the transparent cover 111 is bent, and the side surface of the display module 11 is curved. Further, the first curved portion 1112 may surround the first flat portion 1111, so that each side surface of the display module 11 is curved. The transparent cover 111 may be an integrally formed structure.

In some embodiments, the display panel 112 may be attached to the first flat portion 1111, so that the front surface of the display module 11 can display a picture; the first bending portion 1112 may be attached with some LED lamps to blink when the electronic device 10 receives a short message, a WeChat message, a QQ message, or the like, so as to remind the user, or may blink along with a music rhythm when the electronic device 10 plays music, so as to create a music atmosphere.

In some other embodiments, the display panel 112 may include a main display portion 1121 and a sub display portion 1122, and the sub display portion 1122 is connected to the main display portion 1121, and the two are in smooth transition. The main display portion 1121 is attached to the first flat portion 1111, and the sub-display portion 1122 is attached to the first curved portion 1112, so that the edge area of the display panel 112 is curved, the front and the side of the display module 11 can display the image, and the electronic device 10 can provide a larger display view for the user. Further, the sub-display portion 1122 may surround the main display portion 1121, so that each side of the display module 11 can display a screen.

In the embodiment of the present application, after the display panel 112 is attached to the transparent cover 111, the minimum bending radius of the sub-display portion 1122 relative to the main display portion 1121 may be 6mm, that is, the minimum curvature radius of the display module 11 may be 6 mm. Taking a mobile phone as an example, the thickness of the whole mobile phone is generally less than 10mm, and the curvature radius of the value enables the side surface of the mobile phone to display more pictures, so that the mobile phone can provide a larger display visual field for a user.

The rear cover plate 12 may include a second straight portion 121 and a second curved portion 122, and the second curved portion 122 surrounds the second straight portion 121 and is in smooth transition with the second straight portion 121. The second bent portion 122 is bent toward a direction close to the middle frame 13 so that the edge area of the rear cover panel 12 is bent. The rear cover plate 12 may be an integrally formed structure.

In some embodiments, the first bending portion 1112 (and the secondary display portion 1122) and the second bending portion 122 may be connected to two opposite surfaces of the middle frame 13 by one or a combination of clamping, gluing, welding, and the like, so as to achieve assembly between the display module 11, the rear cover 12, and the middle frame 13. Further, in order to increase the waterproof and dustproof performance of the electronic device 10, glue such as foam and glue may be disposed at the assembly connection positions of the display module 11, the rear cover plate 12 and the middle frame 13.

In some other embodiments, the first flat portion 1111 and the second flat portion 121 may also be slightly curved, for example, both curved in a direction away from the middle frame 13, so that the thickness of the electronic device 10 gradually decreases from the middle area to the peripheral area.

It should be noted that the integrally formed structure in the embodiment of the present application means that the structure of the product is an organic whole, and the product cannot be easily split or divided. For example: the embodiment of the present application may use a thermal bending or heat absorption technique to bend the flat tempered glass into the curved transparent cover 111 according to predetermined process parameters, as shown in fig. 1 and 2, and the curved portion and the straight portion are naturally in a circular arc transition. The above process parameters can be reasonably designed according to factors such as the type of raw material, the bending angle and the curvature radius, and are not limited herein. Further, the OLED screen in a flat plate form may be attached to the transparent cover plate 111 to form the curved display panel 112. Therefore, in fig. 1 and 2, a line between the first straight portion 1111 and the first bent portion 1112, a line between the main display portion 1121 and the sub display portion 1122, and a line between the second straight portion 121 and the second bent portion 122 are mainly for illustrating boundaries between the above-described portions. In other words, for the transparent cover 111, the display panel 112 and the rear cover 12 in the actual product, the lines are not true, i.e. the lines smoothly transition between the parts.

The middle frame 13 may include a frame 131 and a middle plate 132, which are connected to form an open structure with a certain volume, so that the display module 11, the rear cover 12 and the middle frame 13 are assembled to form the cavity structure. The material of the frame 131 may be metal, the material of the middle plate 132 may be rigid plastic, and the two may be made into the middle frame 13 by injection molding, that is, the middle frame 13 may be an integrally formed structural member, so that the structure of the middle frame 13 may be simplified, and the manufacturing cost of the middle frame 13 may be reduced. At this time, the frame 131 may be exposed to the external environment and has an appearance surface capable of playing a role of decoration; the middle plate 132 is mainly located inside the electronic device 10, and can play a role in mounting and fixing the above-mentioned components such as the battery, the main board, the fingerprint module, the camera module, the antenna module, and the like. Of course, the frame 131 and the middle plate 132 may also be formed into an integral structure by a forming process such as punch forming, thermal absorption forming, etc. according to different materials of the middle frame 13. In other embodiments, the frame 131 and the middle plate 132 may be two separate structural members, and they may be assembled by one or a combination of clamping, gluing, welding, screwing, and the like.

Referring to fig. 3 and 4 together, fig. 3 is a schematic side structure diagram of the electronic device in fig. 1, and fig. 4 is a schematic side structure diagram of another embodiment of the electronic device in fig. 1.

In some embodiments, as shown in fig. 3, the display module 11 and the rear cover 12 may not only be configured to be bent in four sides in appearance, but also be configured to be symmetrical with respect to the middle frame 13 (especially, the frame 131) in appearance, so that the electronic device 10 can create a symmetrical aesthetic feeling for users. At this time, the maximum outline of the electronic device 10 is located in the middle frame 13 (specifically, the frame 131), as indicated by the dotted line indicated by the arrow a in fig. 3.

In other embodiments, as shown in fig. 4, the display module 11 may further be curved toward the middle frame 13 based on the above-mentioned symmetrical structure. That is, in the thickness direction of the electronic device 10, the bending depth H1 of the display module 11 is greater than the bending depth H2 of the rear cover 12 (specifically, the bending depth of the first bending portion 1112 may be greater than the bending depth of the second bending portion 122), as shown in fig. 4, so as to increase the lateral display area of the display module 11, thereby enabling the electronic device 10 to provide a larger display view for a user. At this time, the maximum outline of the electronic device 10 is located at the first curved portion 1112 of the display module 11, as indicated by the dotted line indicated by the arrow B in fig. 4.

It should be noted that the maximum outline described in the embodiment of the present application may refer to a contour line corresponding to the maximum projection area when the electronic device 10 is projected in the thickness direction.

Referring to fig. 5 and 6 together, fig. 5 is a partially enlarged structural view of a portion C in fig. 1, and fig. 6 is a partially enlarged structural view of a portion D in fig. 2.

Based on the above detailed description, since the display module 11 and the rear cover 12 may be both curved structures that are curved toward the middle frame 13, when the display module 11, the rear cover 12 and the middle frame 13 are connected, an arc-shaped space is formed between the display module 11 and the rear cover 12. At this time, one surface of the middle plate 132 close to the display module 11 may be a curved surface having the same or similar curvature radius as the display module 11 (specifically, the sub-display portion 1122), and one surface of the middle plate 132 close to the rear cover 12 may be a curved surface having the same or similar curvature radius as the rear cover 12 (specifically, the second bending portion 122), as shown in fig. 5 and 6, so that the middle plate 132 can better support the display module 11 and the rear cover 12 through the curved surface structure, thereby increasing the overall structural strength of the electronic device 10 and further increasing the reliability of the electronic device 10.

In other embodiments, for example, when the curvature radius of the display module 11 and the rear cover 12 is large (that is, the curvature degree is small), one surface of the middle plate 132 close to the display module 11 and the rear cover 12 may also be a straight plane, so as to simplify the structure of the middle plate 132, and thus reduce the processing difficulty of the middle frame 13. At this time, the gaps between the display module 11, the rear cover 12 and the middle plate 132 may be filled with glue such as foam and glue.

Further, two surfaces of the border between the middle plate 132 and the frame 131 may be recessed toward each other to form a first groove 133 and a second groove 134. Wherein, the first groove 133 is close to the display module 11, and the second groove 134 is close to the rear cover 12, as shown in fig. 5; and the distance between the first recess 133 and the second recess 134 is smaller than the width of the outer surface of the bezel 131 in the thickness direction of the electronic device 10, as shown in fig. 6. The configuration is such that the display module 11 can extend to the first groove 133 along the curved surface of the middle plate 132, and the rear cover 12 can extend to the second groove 134 along the curved surface of the middle plate 132, as shown in fig. 5, so that the display module 11 and the rear cover 12 can be partially hidden in the middle frame 13. That is, the middle frame 13 can protect the side edges of the display module 11 and the rear cover 12 to some extent, thereby increasing the reliability of the electronic device 10.

In this embodiment, the width of the appearance surface of the frame 131 in the thickness direction of the electronic device 10 may be less than or equal to 1.8 mm; preferably, the width is greater than or equal to 1.4mm and less than or equal to 1.6mm, so that the display module 11 and the rear cover plate 12 can extend more toward each other along the middle plate 132, thereby enabling the electronic device 10 to provide a larger display view for a user. Accordingly, the appearance surface of the frame 131 may be a straight plane or an arc convex surface, so that the electronic device 10 can obtain better appearance and holding feeling. Further, the middle frame 13 is thinned from the inside to the outside of the electronic device 10 in the whole structure, as shown in fig. 5 and 6, so that the middle frame 13 can meet both requirements of ultra-thinning and structural strength, thereby increasing the reliability of the middle frame 13.

The size of the black border of the display module 11 (specifically, the first straight portion 1112 and the sub-display portion 1122) and the matching relationship between the black border and the middle frame 13 (specifically, the frame 131 and the portion of the middle plate 132 close to the frame 131) will be described in detail below:

referring to fig. 7 and 8 together, fig. 7 is a schematic cross-sectional structure along direction VII-VII of an embodiment of the electronic device in fig. 1, and fig. 8 is a schematic cross-sectional structure of another embodiment of the electronic device in fig. 7. It should be noted that fig. 7 and fig. 8 may be enlarged schematic views of the electronic device, mainly for convenience of the related description later.

Generally, the display module 11 may be divided into a display area (shown as AA in fig. 7 or 8) and a non-display area (shown as NA in fig. 7 or 8), and the non-display area may surround the display area. Among them, a dotted line in fig. 7 or fig. 8 may be used as a boundary between the display region and the non-display region. Furthermore, the display area is mainly used for displaying a picture, so that the display module 11 can present the picture; the non-display area is mainly used for shielding the edge defects of the display module 11 and for arranging various circuits (commonly referred to as "wires") of the display module 11. Therefore, the non-display area is usually coated with ink (usually black, not shown), and the ink is usually coated on the side of the transparent cover 111 close to the display panel 112. In this case, the width of the non-display area may be regarded as the size of the black border of the display module 11. Obviously, the smaller the black edge of the display module 11 is, the larger the relative area of the display area thereof is, and then the larger the screen occupation ratio of the display module 11 is.

In the embodiment of the present application, since the side edge of the display module 11 may be a curved surface structure, the non-display area is located at a curved portion of the display module 11 corresponding to the first curved portion 1112 and the secondary display portion 1122, as shown in fig. 7 or fig. 8. So set up, because the curved surface structure of display module assembly 11 has certain refraction effect to light for the black limit of display module assembly 11 can obtain the reduction of certain degree in the vision, thereby makes electronic equipment 10 can bring the vision that bigger screen accounts for and compare to experience for the user.

At this time, the visual black border (the size of which is denoted by NA') that the user can view from the front of the display module 11 should be a projection of the actual black border (the size of which is denoted by NA) in the thickness direction of the electronic device 10, and the size relationship between the two can be roughly described as follows: NA ═ NA · cos (θ). As shown in fig. 7 or 8, θ may represent the degree of the bending angle of the first bending portion 1112 toward the middle frame 13 relative to the first flat portion 1111, that is, the degree of the bending of the display module 11 toward the middle frame 13. Obviously, in the case that the actual black border size NA of the display module 11 is constant, the larger the value of θ is, the smaller the visual black border size NA' viewed by the user from the front of the display module 11 is.

In some embodiments, as shown in fig. 7, the projection of the first curved portion 1112 on the display panel 112 exceeds the range of the sub-display portion 1122, that is, the transparent cover 111 is larger than the display panel 112, so that the transparent cover 111 partially protrudes from the display panel 112. This is mainly set to "tolerate" the error of the display panel 112 attached to the transparent cover 111. At this time, the actual black border NA of the display module 11 mainly includes two parts, namely, a part of the transparent cover 111 protruding the display panel 112 (as shown by L1 in fig. 7), and a part of the display panel 112 used for routing (as shown by L2 in fig. 7). Obviously, the actual black border size NA of the display module 11 is (L1+ L2). Generally, the size of L1 may be 0.3mm, and the size of L2 may be 0.9 mm.

The inventors of the present application found in long-term studies that: since the size of the L2 is mainly limited by the traces of the display module 11, it is generally difficult to simply optimize the size. In contrast, the size of the L1 is mainly determined by the bonding process of the display panel 112 and the transparent cover 111, and is mainly for "tolerating" the error of the display panel 112 bonded to the transparent cover 111. Therefore, the L1 is easier to optimize in size than the L2 in the case of L1. Therefore, on the basis of the above embodiments, the following embodiments are suggested in a new way.

In some other embodiments, as shown in fig. 8, the projection of the first bending portion 1112 on the display panel 112 falls within the range of the sub-display portion 1122, that is, the size of the transparent cover 111 is smaller than that of the display panel 112, so that the transparent cover 111 is partially recessed in the display panel 112, that is, the display panel 112 protrudes from the transparent cover 111. At this time, the actual size NA of the black border of the display module 11 mainly depends on the size of the transparent cover 111 recessed in the display panel 112. As shown in fig. 8, when the display module 11 has no change in the routing, the size of the L2 is substantially unchanged; if the size of the portion of the display panel 112 protruding from the transparent cover 111 is L3, the actual black border NA of the display module 11 is (L2-L3). In any case, the actual black-edge size (L2-L3) of the display module 11 in the present embodiment is smaller than the actual black-edge size (L1+ L2) of the display module 11 in the above-described embodiment.

The inventors of the present application have also found in long-term studies that: if the display panel 112 protrudes too much from the transparent cover 111 (i.e. the L3 is too large), the display panel 112 may be separated from the transparent cover 111 due to too much tension, which may cause the quality of the display module 11 to be poor. Therefore, in the present embodiment, the size of L3 may be any value (in mm) within the closed interval [0,0.5 ]. Preferably, the size of L3 may be any value (in mm) within the closed range [0,0.4 ]. Note that, when the value of L3 is 0, it can be considered that the projection of the first curved portion 1112 in the thickness direction of the electronic device 10 overlaps the projection of the sub display portion 1122 in the thickness direction of the electronic device 10.

Further, since the relative sizes of the display panel 112 and the transparent cover 111 are changed in this embodiment, that is, the specific structure of the display module 11 is changed, the display module 11 may not be adapted to the original middle frame 13. For this reason, the main differences from the above-described embodiments are also: in this embodiment, the electronic device 10 may further include a decoration 14, and the decoration 14 is mainly used for transition between the display module 11 and the middle frame 13, and can protect the display module 11. As shown in fig. 8, the garnish 14 may be specifically provided between the first bending portion 1112, the sub-display portion 1122, and the center frame 13. Further, since the display module 11 may have a four-side curved structure, the decoration 14 may also have a ring structure.

In this embodiment, the transparent cover 111 may serve as an outer surface of the electronic device 10, so that at least the first bending portion 1112 in the first bending portion 1112 and the sub-display portion 1122 may contact the garnish 14 to reduce a gap between the transparent cover 111 and the garnish 14, thereby increasing the structural compactness of the electronic device 10.

It should be noted that, because there may be an assembly error between the display module 11 and the decoration 14, the "contact" described in this embodiment does not strictly refer to that the gap between the transparent cover plate 111 and the decoration 14 is zero; but it is intended to state that the gap between the two may be so small that it can be completely ignored.

Referring to fig. 8 and 9 together, fig. 9 is a schematic structural view of an embodiment of the decoration device in fig. 8.

As shown in fig. 9, the decoration 14 may include a connecting surface 141, a mating surface 142, and a decoration surface 143 connected end to end in this order. Wherein, the connecting surface 141 is close to the middle frame 13, so that the decoration 14 can be connected with the middle frame 13 through the connecting surface 141. Further, the mating surface 142 is close to the first curved portion 1112 and the sub-display portion 1122. The decorative surface 143 is exposed to the electronic device 10, that is, a part of the decorative member 14 may be an outer surface of the electronic device 10. Therefore, the material of the decoration 14 may be the same as or similar to that of the middle frame 13 (especially, the frame 131) and the rear cover 12.

Further, as shown in fig. 9, the attachment face 141 may be provided with a boss 144. Accordingly, as shown in fig. 8, the middle frame 13 is opened with a groove 135 corresponding to the protrusion 144. At this time, the portion of the middle frame 13 (specifically, the frame 131) provided with the groove 135 may be formed with a surface (not labeled in fig. 8) that is matched with the connection surface 141. So configured, the protrusion 144 can be engaged with the groove 135 to connect the decoration 14 with the middle frame 13. The decoration 14 and the middle frame 13 may be dispensed to increase the bonding strength between the two. Obviously, after the garnish 14 is assembled with the middle frame 13, the garnish 14 can be simply regarded as a partial structure of the middle frame 13. Therefore, the garnish 14 and the center frame 13 may be formed integrally.

In some embodiments, as shown in fig. 9, the mating surface 142 may be parallel to a thickness direction of the electronic device 10. In fig. 9, a dotted line may indicate a thickness direction of the electronic device 10. At this time, the first curved portion 1112 and the sub-display portion 1122 may contact the mating surface 142, so that the gap between the transparent cover 111 and the garnish 14 may be reduced, thereby increasing the compactness of the electronic apparatus 10 in structure.

In other embodiments, as shown in FIG. 10, the mating surface 142 may be angled with respect to the thickness direction of the electronic device 10. In fig. 10, a dotted line may indicate a thickness direction of the electronic device 10. For example: the distance between mating surface 142 and the dashed line in fig. 10 increases gradually in the direction of approach to boss 144, so that trim piece 14 forms a narrow-top-wide-bottom structure at mating surface 142. On one hand, the first bending portion 1112 and the sub-display portion 1122 may also contact the mating surface 142, so that the gap between the transparent cover 111 and the decoration 14 may be reduced, thereby increasing the compactness of the electronic device 10 in structure. On the other hand, after the decoration 14 is assembled with the middle frame 13, a larger accommodating area can be formed between the decoration 14 and the middle frame 13, so that the requirements on the manufacturing error and the assembling error of the display module 11 are reduced.

Further, in order to adapt to the narrow-top and wide-bottom structure of the decoration 14, so that the display module 11 and the decoration 14 can be assembled with the middle frame 13, the present embodiment further provides a fitting jig 20. The attaching jig 20 may include a lower mold 21 and an upper mold 22, and a parting surface 23 between the upper mold 22 and the lower mold 21 may correspond to a position of the decoration 14. At this time, the process of assembling the electronic device 10 by the attaching jig 20 may include the following steps:

in the first step, the lower mold 21 may fix the back cover plate 12 and the middle frame 13 by vacuum suction. Wherein, the rear cover plate 12 and the middle frame 13 can be assembled in advance.

In the second step, the upper mold 22 may fix the display module 11 by vacuum adsorption, and attach the display module 11 to the middle frame 13. Colloid (not shown in fig. 11) such as foam and glue can be disposed between the display module 11 and the middle frame 13, so that the display module and the middle frame are fixed conveniently.

Fourthly, the semi-finished product assembled by the display module 11 and the middle frame 13 (and the rear cover plate 12) is taken out from the attaching jig 20.

And a fifth step of mounting the decoration 14 on the middle frame 13 based on the semi-finished product. At this time, due to the narrow-top and wide-bottom structure of the decoration 14, the decoration 14 can be assembled with the middle frame 13, and can also "tolerate" the manufacturing error of the display module 11 and the assembling error.

Further, before the fifth step, glue may be dispensed on a portion of the display module 11 near the frame 131, so that after the decoration is assembled with the middle frame 13, the glue 145 is filled between the mating surface 142 and the first bending portion 1112 and the sub-display portion 1122. So set up, can avoid display module assembly 11,
