Description

Electronic device

[0001] This application claims priority to the Chinese patent application No. 202411134812.5, filed on August 16, 2024, entitled "Electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of display devices, in particular to an electronic device. BACKGROUND

[0003] With the development of technology, display devices are pursuing the limit of "black border" around the display area, so that the display device can have a narrow frame (the smaller the width of "black border", the narrower the frame), thereby highlighting the display area itself, providing consumers with a wider field of view under the condition of unchanged screen size, and making the appearance of the product more delicate and high-end. Especially for smart electronic devices such as watches, because the display area is small, the reduction of the frame is particularly important. SUMMARY

[0004] The present application provides an electronic device with narrow-frame display.

[0005] In a first aspect, an electronic device is provided. The electronic device includes a housing and a screen. The screen includes a cover plate and a display assembly. The cover plate is fixed to the housing and surrounds a containing space with the housing. The display assembly is fixedly connected to the cover plate. The display assembly is located in the containing space. The screen further includes a driving assembly and an electrical connection assembly. The driving assembly and the electrical connection assembly are both located in the containing space. The driving assembly is fixedly connected to a side of the display assembly away from the cover plate. The electrical connection assembly is electrically connected to the display assembly at one end and electrically connected to the driving assembly at the other end. The electrical connection assembly is at least partially located on a side of the display assembly. An outer edge of the electrical connection assembly is flush with an outer edge of the cover plate, or the outer edge of the electrical connection assembly is at least partially located on an outer side of the cover plate.

[0006] The outer edge of the electrical connection assembly refers to a side of the electrical connection assembly away from the side of the display assembly. The outer edge of the cover plate refers to the circumference of the cover plate. The projection of the outer edge of the electrical connection assembly on the reference surface in the first direction is a first projection, the projection of the outer edge of the cover plate on the reference surface in the first direction is a second projection, and the projection of the center of the cover plate on the reference surface in the first direction is a third projection. The first direction is the thickness direction of the cover plate. The reference surface is perpendicular to the first direction. The outer edge of the electrical connection assembly is flush with the outer edge of the cover plate refers to the distance between the first projection and the third projection is equal to the distance between the second projection and the third projection. The outer edge of the electrical connection assembly is located on the outer side of the cover plate refers to the distance between the first projection and the third projection is greater than the distance between the second projection and the third projection.

[0007] It can be understood that the driving assembly is fixedly connected to the display assembly on a side away from the cover plate, that is, the driving assembly can be fixedly connected to the bottom surface of the display assembly. The electrical connection assembly needs to be routed from the side surface of the display assembly to achieve electrical connection between the driving assembly and the display assembly. The electrical connection assembly is at least partially located on the side surface of the display assembly.

[0008] The mounting clearance between the electrical connection assembly and the housing can be located on the outer side of the screen, that is, the projection of the mounting clearance on the reference surface in the first direction is offset from the projection of the screen on the reference surface in the first direction, which is beneficial to reduce the "black border" of the screen, improve the screen-to-body ratio of the electronic device, and improve the user experience. In addition, in the first direction, the part of the outer edge of the cover plate that is opposite to the electrical connection assembly can be arranged to be offset from the housing in the first direction, and the other part of the outer edge of the cover plate is used for fixedly connecting the housing. In this way, the bonding width of the cover plate at this position can be reduced, and the "black border" width is further reduced.

[0009] In some possible implementation manners, the housing includes a front wall, a side wall and a back wall, the front wall and the back wall are arranged opposite to each other in the first direction, and the side wall is connected between the front wall and the back wall. The cover plate is mounted on the front wall, and the first direction is the thickness direction of the cover plate.

[0010] It can be understood that when the user uses the electronic device, the front wall can face the side where the user is located. The screen can be located on the side facing the user. The electrical connection assembly is at least partially located on the side surface of the display assembly, that is, in the second direction, at least part of the electrical connection assembly is opposite to the side surface of the display assembly. The second direction is a direction in which the containing space faces the outer side of the side wall of the housing. The outer edge of the electrical connection assembly can refer to the edge of the electrical connection assembly that is farthest from the side surface of the display assembly in the second direction.

[0011] In some possible implementation manners, the projection of the front wall on the electrical connection assembly in the first direction partially overlaps the electrical connection assembly.

[0012] It can be understood that the electrical connection assembly can be partially located on the inner side of the front wall of the housing, and the inner side of the front wall refers to the side of the front wall facing the containing space. The clearance between the electrical connection assembly and the housing can overlap the front wall in the first direction, further reducing the "black border" width.

[0013] In some possible implementation manners, the side wall is provided with an avoiding groove, the opening of the avoiding groove faces the side surface of the display assembly, and part of the electrical connection assembly is located in the avoiding groove.

[0014] It can be understood that, by setting the avoiding groove, the space in the avoiding groove can be used as the avoiding gap between the electric connection assembly and the shell, so as to reduce the risk of collision between the electric connection assembly and the shell during the installation of the screen.

[0015] In some possible implementation manners, gaps exist between the cover plate, the display assembly and the side wall, and the electronic device further comprises a waterproof ring, which fills the gaps.

[0016] It can be understood that the waterproof ring can be used to seal the gaps between the cover plate, the display assembly and the shell, so as to prevent water vapor from the outside from entering the accommodation space through the gaps between the screen and the shell, thereby causing the failure of the devices in the accommodation space and the malfunction of the electronic device.

[0017] In some possible implementation manners, the waterproof ring comprises a first part and a second part connected in a circumferential direction, and the first part is fixedly connected to the electric connection assembly. That is, the part of the waterproof ring connected to the electric connection assembly is the first part.

[0018] In some possible implementation manners, the first part and / or the second part of the waterproof ring is made of glue material.

[0019] It can be understood that the glue material can be glue (having fluidity between solidification) or adhesive film (solid having adhesion). The glue material has adhesion, and the first part and / or the second part of the waterproof ring can be used to bond the screen and the shell, thereby further enhancing the connection strength between the screen and the shell and reducing the risk of cracking of the screen and the shell.

[0020] In some possible implementation manners, the first part of the waterproof ring is made of glue material, and the second part of the waterproof ring is made of plastic. It can be understood that the first part and the second part can be made of different materials.

[0021] In some possible implementation manners, the electronic device further comprises an adhesive layer fixedly connected between the second part of the waterproof ring and the shell.

[0022] It can be understood that, by setting the adhesive layer, the connection strength between the second part of the waterproof ring and the shell can be enhanced, and the risk of gap between the waterproof ring and the shell can be reduced, thereby reducing the risk of water entering the electronic device. Exemplarily, the adhesive layer can be double-sided adhesive tape or other materials having adhesion.

[0023] In some possible implementation manners, the second part of the waterproof ring is made of glue material. The shell further comprises a boss fixedly connected to the inner side of the side wall, the cover plate is at least partially located on the inner side of the side wall and is arranged opposite to the boss in the first direction. The electronic device further comprises a flexible member located between the boss and the cover plate.

[0024] It can be understood that the material adopted by the second part can include glue material, the second part can have bonding capacity, and can be used for bonding the screen and the shell, further strengthening the connection strength between the screen and the shell. The waterproof reliability of the waterproof ring is better when the screen is pulled away from the shell under the action of mechanical force.

[0025] The cover plate is at least partially located on the inner side of the side wall, avoiding the display assembly from being exposed to the shell, and the display assembly can be better protected. By arranging the boss, the boss can be used as a positioning structure in the Z-axis direction when assembling the screen and the shell, for confirming the position of the screen relative to the shell, reducing the use of molds. In addition, the boss can also increase the connection area between the screen and the shell.

[0026] The second part can be formed by a dispensing or pouring process. The dispensing or pouring process has lower preparation cost than the injection molding process, and the second part of the waterproof ring is formed by the dispensing or pouring process, which is conducive to reducing the preparation cost of the waterproof ring.

[0027] The flexible piece can be used to communicate the gap and the accommodation space, so that the screen and the boss are at least partially spaced apart, and can be used as a dispensing or pouring passage.

[0028] In some possible implementation manners, the material adopted by the second part of the waterproof ring includes glue material and pressure-sensitive material.

[0029] It can be understood that, in the process of assembling the screen and the shell, a certain pressure is applied to the screen and the shell, so that the second part of the waterproof ring can be better formed and fill the gap. For example, the second part of the waterproof ring can adopt a glue film. The glue film scheme adopted by the second part replaces the pouring and dispensing, and the thickness consistency of the glue film is good, and the uniformity is better controlled than the dispensing. In addition, if the glue film fails to be bonded with the middle frame, the glue film can be reworked like a conventional dispensing process, and the cost is low. Compared with the injection molding process, the cost of the screen is also lower than that of the waterproof ring formed by the LTVP forming scheme.

[0030] In some possible implementation manners, the first part of the waterproof ring and the second part of the waterproof ring are integrally formed structural pieces.

[0031] It can be understood that the integration of two components by the integrally formed process means that, in the process of forming one of the two components, the component is connected with the other component together, without the need for connecting the two components together by reprocessing (such as bonding, welding, buckle connection, screw connection). The first part of the waterproof ring and the second part of the waterproof ring are integrally formed structural pieces, reducing the preparation steps and improving the production efficiency.

[0032] In some possible implementation manners, the electric connection assembly comprises a bending part, the bending part and the side surface of the display assembly enclose a space, and a part of the waterproof ring is filled in the space. In this way, the waterproof ring can support the bending part of the electric connection assembly and better seal water.

[0033] In some possible implementation manners, the electric connection assembly comprises a first electric connection part and a second electric connection part, one end of the first electric connection part is electrically connected to the display assembly, the other end of the first electric connection part is electrically connected to one end of the second electric connection part, and the other end of the second electric connection part is electrically connected to the driving assembly. The first electric connection part is in contact with the side surface of the display assembly, and the first electric connection part is made of conductive paste.

[0034] It can be understood that the first electric connection part can be made of conductive paste, the conductive paste has fluidity before solidification, can better adapt to the shape of the side surface of the display assembly, and can realize the electrical connection between the driving assembly and the display assembly. The risk of the electric connection assembly being separated from the display assembly and the driving assembly due to excessive stress after being bent can be reduced. The electric connection assembly does not need to be bent, the connection reliability between the electric connection assembly and the display assembly and the driving assembly is higher, and the electrical connection is more reliable. In the scheme of the electric connection assembly and the side surface of the display assembly being directly connected, there is no gap between the side surface of the electric connection assembly and the side surface of the display assembly, and the "black border" in the scheme of the present application can be smaller. When the screen is mounted on the shell, the angle of the screen in the oblique insertion process can be reduced, or the screen does not need to be obliquely inserted and can be mounted on the shell.

[0035] In some possible implementation manners, the display assembly comprises a transparent adhesive layer, a polarizing sheet and a display panel which are arranged in a stack, and the transparent adhesive layer is connected between the cover plate and the polarizing sheet.

[0036] It can be understood that the transparent adhesive layer is used for bonding between the display assembly and the cover plate. The polarizing sheet can be used for anti-glare or to make light at a certain angle exit the screen.

[0037] In some possible implementation manners, the driving assembly comprises a circuit board and a driving chip, the driving chip is electrically connected to the circuit board, and the electric connection assembly is electrically connected to the driving chip.

[0038] It can be understood that the driving chip can directly contact and be electrically connected to the electric connection assembly, or the driving chip can be indirectly electrically connected to the electric connection assembly through the circuit board. The circuit board can also be used for signal transmission between the driving chip and the main board of the electronic device.

[0039] In some possible implementation manners, the electric connection assembly comprises one or more of a chip on film, a circuit board and conductive paste.

[0040] It can be understood that the electric connection assembly can include a chip-on-flex (COF), a flexible printed circuit (FPC) or the like flexible electric transmission structure. Part of the electric connection assembly can be bent, so as to facilitate the electric connection between the driving assembly and the display panel which are arranged in a stack in the first direction. The electric connection assembly is not easy to fall off from the driving assembly or the display panel, and the electric connection reliability is better.

[0041] The electric connection assembly can also include a conductive paste. The conductive paste has fluidity before curing, so as to present an arbitrary shape on the surface of the peripheral structure, thereby facilitating the electric connection between the driving assembly and the display panel which are arranged in a stack. The electric connection assembly is not easy to fall off from the driving assembly or the display panel, and the electric connection reliability is better.

[0042] In some possible implementation manners, the electronic device is a wearable device.

[0043] It can be understood that when the electronic device is a wearable device, the area of the screen is small, and therefore the width of the "black border" is reduced, and the screen-to-body ratio can be significantly improved, thereby better improving the user experience.

[0063] The embodiments of the present application will be described below in conjunction with the accompanying drawings. The embodiments described herein by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0064] In the description of the embodiments of the present application, it should be noted that unless specifically defined and limited otherwise, the terms "mount", "connect" should be interpreted broadly, for example, "connect" can be detachable connection, but also can be non-detachable connection; can be direct connection, but also through the intermediate medium indirect connection. It should be understood that in the present application, "electrical connection" can be understood as the physical contact and electrical conduction of the elements; it can also be understood as the form of connection between different elements in the circuit structure through the entity line of the copper foil or wire of the printed circuit board (PCB) which can transmit electrical signals. "Connect", "connected" can refer to a mechanical connection relationship or a physical connection relationship, for example, A and B are connected or A and B are connected, which can mean that there is a fastening component (such as a screw, a bolt, a rivet, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0065] Furthermore, "fixed" in this paper should also be interpreted broadly, for example, "fixed" can be direct fixation, but also through the intermediate medium indirect fixation. Among them, "fixed" means connected to each other and the relative position relationship after connection is unchanged. The orientation language mentioned in the embodiments of the present application, such as "upper", "lower", etc., is only the direction of the drawing, therefore, the orientation language used is to better, more clearly illustrate and understand the embodiments of the present application, and is not indicative or implied that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, therefore, it cannot be understood as a limitation on the embodiments of the present application. "Multiple" means two or more than two.

[0066] In the description of the embodiments of the present application, unless otherwise stated, " / " means or, for example, A / B can mean A or B; "and / or" in the text only describes the relationship between the associated objects, which means that there can be three relationships, for example, A and / or B, which can mean that A exists alone, A and B exist together, and B exists alone, in addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0067] In the embodiments of the present application, the terms "first", "second", "third", "fourth" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features limited by "first", "second", "third", "fourth" can explicitly or implicitly include one or more of the features.

[0068] In addition, in the embodiments of the present application, the relative position relationship mentioned, such as parallel, perpendicular, alignment and the like, are all relative to the current process level, and are not absolute strict limits, and a small amount of deviation is allowed, and approximately parallel, approximately perpendicular, approximately alignment and the like are all acceptable. For example, A is parallel to B, which means that A and B are parallel or approximately parallel, and the included angle between A and B is between 0 degree and 10 degree. For example, A is perpendicular to B, which means that A and B are perpendicular or approximately perpendicular, and the included angle between A and B is between 80 degree and 100 degree.

[0069] FIG. 1 is a partial cross-sectional view of an embodiment of an electronic device 1000 in the prior art. As shown in FIG. 1, the screen 10 of the electronic device 1000 includes a cover plate 1, a display assembly 2, an electrical connection assembly 4 and a driving assembly 3, and the positional relationship between the cover plate 1, the display assembly 2, the electrical connection assembly 4, the driving assembly 3 and the housing is shown.

[0070] As shown in FIG. 1, in the assembly scheme of the screen 10 of the electronic device 1000 in the prior art, the cover plate 1 can be fixed to the housing 20 by the adhesive 1001, and the cover plate 1 and the housing 20 enclose a containing space 40. The display assembly 2, the driving assembly 3 and the electrical connection assembly 4 are all arranged in the containing space 40. The driving assembly 3 is arranged on the back of the display assembly 2. The back of the display assembly 2 refers to the side surface of the display assembly 2 away from the cover plate 1. One end of the electrical connection assembly 4 is fixedly connected to the display assembly 2, and the other end is fixedly connected to the driving assembly 3. The driving assembly 3 and the display assembly 2 are electrically connected through the electrical connection assembly 4. The electrical connection assembly 4 is at least partially located on the side of the display assembly 2.

[0071] When the electronic device 1000 displays an image, a ring of "black border" will appear around the display area (Active Area, AA) of the screen 10. The "black border" can be composed of the structure (for example, the non-display area of the display panel, the electrical connection component located on the side of the display assembly 2) S1 under the cover plate 1 which cannot display, the avoiding gap S2 and the bonding area S3 of the cover plate 1 and the housing. It can be understood that the ratio of the area of the display area to the area of the "black border" can also be referred to as the screen-to-body ratio. When the sum of the areas of the display area and the "black border" is constant, the smaller the "black border" is, the larger the display area is, and the larger the screen-to-body ratio is. Improving the screen-to-body ratio of the electronic device 1000 is beneficial to improving the user experience.

[0072] It is understood that the widths of the black borders around the display area can not be the same. The width D of the black border refers to the width of the black border in the direction in which the accommodation space 40 faces the outside of the side wall of the housing 20. For example, among the black borders around the display area (AA), the width of the black border on the side where the electrical connection assembly 4 is located can be larger. It is understood that the location where the electrical connection assembly 4 is located can be any location around the display area (AA) and is not limited to a certain side.

[0073] FIG. 2 is a structural schematic diagram of an embodiment of the electronic device 1000 provided in the present application. For ease of description, as shown in FIG. 1, the length direction of the electronic device 1000 is defined as the X axis. The width direction of the electronic device 1000 is defined as the Y axis. The thickness direction of the electronic device 1000 is defined as the Z axis. In other embodiments, the coordinate system can also be flexibly set according to other requirements.

[0074] The electronic device 1000 can include, but is not limited to, a smart watch, a sports watch, a bracelet, augmented reality (AR) glasses, virtual reality (VR) glasses or earphones, and other wearable devices. The electronic device 1000 can also be a terminal product such as a mobile phone, a tablet or a home device. The electronic device 1000 shown in FIG. 1 is described by taking a smart watch as an example. It should be noted that FIG. 1 only schematically shows some components included in the electronic device 1000, and the actual size, actual position and actual structure of these components are not limited by the figure. The following figures also only schematically show some components, and the actual size, actual position and actual structure of these components are also not limited by the following figures, which will not be described in detail below.

[0075] As shown in FIG. 2, the electronic device 1000 can include a watch body 100 and a watchband 200. The watchband 200 is connected to the watch body 100. Exemplarily, the number of watchbands 200 can be two. The two watchbands 200 are respectively connected to the two ends of the watch body 100. When a user wears the electronic device 1000, the watchband 200 can be used to fix the watch body 100 on the user's body. In other embodiments, the number of watchbands 200 can also be one.

[0076] FIG. 3 is an exploded schematic diagram of an embodiment of the watch body 100 shown in FIG. 2.

[0077] As shown in FIGS. 2 and 3, the watch body 100 can include a screen 10, a housing 20 and a waterproof ring 30. The screen 10 can be installed on the housing 20. The screen 10 can be used to display a pattern. The screen 10 can be a flat screen or a curved screen.

[0078] FIG. 4 is a partial cross-sectional view of an embodiment of the table body 100 shown in FIG. 2 along the section line A-A. FIG. 5 is a partial structural schematic view of an embodiment of the screen 10 shown in FIG. 3.

[0079] As shown in FIGS. 3, 4 and 5, the screen 10 can include a cover plate 1, a display assembly 2, a driving assembly 3 and an electrical connection assembly 4. The display assembly 2 can be configured to display an image. The driving assembly 3 can be configured to input a driving signal to the display assembly 2. The electrical connection assembly 4 can be configured to realize signal transmission between the driving assembly 3 and the display assembly 2.

[0080] In some embodiments, the cover plate 1 can be fixed to the housing 20, and the cover plate 1 and the housing 20 can enclose a receiving space 40. The display assembly 2 can be fixedly connected to the cover plate 1. The display assembly 2 can be located in the receiving space 40. The cover plate 1 and the housing 20 can be configured to protect the display assembly 2.

[0081] For example, the cover plate 1 can be made of a light-transmitting material, such as transparent glass or polyimide. In this way, the cover plate 1 does not affect the display of the display assembly 2.

[0082] In some embodiments, the display assembly 2 can include a top surface 21, a bottom surface 22 and a side surface 23. The top surface 21 and the bottom surface 22 are oppositely arranged. The side surface 23 is connected between the top surface 21 and the bottom surface 22. The top surface 21 of the display assembly 2 is a side surface of the display assembly 2 for displaying an image. When a user uses the electronic device 1000, the top surface 21 of the display assembly 2 can face the user. For example, the cover plate 1 can be fixedly connected to the top surface 21 of the display assembly 2.

[0083] For example, the display assembly 2 can include an organic conductive adhesive (OCA) layer 24, a polarizer (POL) 25 and a display panel 26 arranged in a stack. The OCA layer 24 is connected between the cover plate 1 and the polarizer 25. The OCA layer 24 can be configured to bond the display assembly 2 and the cover plate 1. The polarizer 25 can be configured to prevent glare or to allow light at a set angle to exit the screen 10. For example, along the Z-axis direction, the cover plate 1, the OCA layer 24, the polarizer 25 and the display panel 26 are arranged in a stack from top to bottom. In other embodiments, the display assembly 2 can include more or fewer layers.

[0084] Exemplarily, the display panel 26 can be used to display a pattern. The display panel 26 can be an organic light-emitting diode (OLED) display panel 26, or an active-matrix organic light-emitting diode (AMOLED) display panel 26, or a liquid crystal display (LCD), and the like.

[0085] In some embodiments, the driving assembly 3 and the electrical connection assembly 4 can be located in the accommodation space 40. The cover plate 1 and the shell 20 can also be used to protect the driving assembly 3 and the electrical connection assembly 4. Exemplarily, the accommodation space 40 can also be used to place other components of the electronic device 1000, such as a mainboard, a battery, a speaker, or a microphone, and the like.

[0086] In some embodiments, the driving assembly 3 can be electrically connected to the display assembly 2. The driving assembly 3 can be used to input a driving signal to the display assembly 2. For example, the driving assembly 3 can be electrically connected to the display panel 26. The driving assembly 3 can be used to input a driving signal to the display panel 26, so as to make the display panel 26 display an image. Exemplarily, the driving assembly 3 can include a circuit board 302 and a driving chip 301. The driving chip 301 is electrically connected to the circuit board 302. The circuit board 302 can be a printed circuit board, or a flexible circuit board. It can be understood that the driving chip 301 can directly contact the electrical connection assembly 4 and be electrically connected to the electrical connection assembly 4, or the driving chip 301 can indirectly electrically connect to the electrical connection assembly 4 through the circuit board 302. The circuit board 302 can also be used to realize signal transmission between the driving chip 301 and a mainboard of the electronic device 1000.

[0087] In some embodiments, the driving assembly 3 can be fixedly connected to the bottom surface 22 of the display assembly 2. That is, the driving assembly 3 can be fixedly connected to the side of the display assembly 2 away from the cover plate 1. Exemplarily, the driving assembly 3 can be fixed to the side surface of the display panel 26 away from the polarizer 25.

[0088] In some embodiments, one end of the electrical connection assembly 4 can be electrically connected to the display assembly 2, and the other end can be electrically connected to the driving assembly 3. The electrical connection assembly 4 can be used to realize signal transmission between the driving assembly 3 and the display assembly 2. Exemplarily, one end of the electrical connection assembly 4 can be fixedly connected to the display panel 26 and electrically connected to the display panel 26, and the other end can be fixedly connected to the driving assembly 3 and electrically connected to the driving chip 301.

[0089] In some embodiments, the driving component 3 is arranged on the bottom surface 22 of the display component 2. The electrical connection component 4 needs to be routed from the side surface 23 of the display component 2 to achieve electrical connection between the driving component 3 and the display component 2. The electrical connection component 4 is at least partially located on the side surface 23 of the display component 2. In other words, in the second direction, at least part of the electrical connection component 4 and the side surface 23 of the display component 2 are arranged oppositely. The second direction is the direction towards the outside of the side wall 202 of the housing 20. It can be understood that the electrical connection component 4 is at least partially located on the side surface 23 of the display component 2, and the electrical connection component 4 can or can not contact the side surface 23 of the display component 2. Details will be described below with reference to the drawings.

[0090] Exemplarily, the electrical connection component 4 is at least partially located on the side surface of the polarizer 25 and the side surface of the display panel 26. In other embodiments, the electrical connection component 4 can also not be located on the side surface of the polarizer 25. It can be understood that the relationship between the electrical connection component 4 and the side surface of the layer structure included in the display component 2 can be designed according to requirements.

[0091] Exemplarily, the electrical connection component 4 can include a chip-on-flex (COF), a flexible printed circuit (FPC), or other flexible electrical transmission structure. In this way, part of the electrical connection component 4 can be bent, thereby facilitating electrical connection between the driving component 3 and the display panel 26 arranged in the first direction. The electrical connection component 4 is not easy to fall off from the driving component 3 or the display panel 26, and the electrical connection reliability is better.

[0092] Exemplarily, the electrical connection component 4 can also include conductive paste. The conductive paste has fluidity before curing, so that it can present an arbitrary shape on the surface of the surrounding structure, thereby facilitating electrical connection between the driving component 3 and the display panel 26 arranged in the first direction. The electrical connection component 4 is not easy to fall off from the driving component 3 or the display panel 26, and the electrical connection reliability is better.

[0093] It can be understood that the electrical connection component 4 can include one or more of the COF, the FPC, and the conductive paste. Those skilled in the art can selectively arrange according to requirements.

[0094] In some embodiments, the housing 20 can include a front wall 201, a side wall 202, and a back wall 203 (the front wall 201 and the side wall 202 are schematically distinguished by the dashed lines in FIG. 4). The front wall 201 and the back wall 203 can be oppositely arranged in a first direction, and the side wall 202 is connected between the front wall 201 and the back wall 203. The cover plate 1 can be mounted on the front wall 201, and the first direction is the thickness direction of the cover plate 1. In some embodiments, the side wall 202 of the housing 20 can be provided with a through hole, which can be used for mounting the button of the electronic device 1000. Exemplarily, when the user uses the electronic device 1000, the front wall 201 can face the side where the user is located.

[0095] In some embodiments, the housing 20 can include a middle frame 204 and a back cover 205. The middle frame 204 and the back cover 205 can be detachably connected. The screen 10 can be oppositely spaced apart from the back cover 205, and the middle frame 204 is connected between the screen 10 and the back cover 205. Exemplarily, the cover plate 1 of the screen 10 can be fixedly connected to the middle frame 204 of the housing 20. When the user wears the electronic device 1000, the screen 10 can be located on the side of the watch body 100 facing away from the user's wrist skin, and the back cover 205 can be located on the side of the watch body 100 facing the user's wrist skin, and the back cover 205 can contact the user's wrist skin.

[0096] In other embodiments, the front wall 201, the side wall 202, and the back wall 203 of the housing 20 can also be an integrally formed structural member.

[0097] FIG. 6 is a structural schematic diagram of an embodiment of the middle frame 204 shown in FIG. 3. FIG. 7 is a structural schematic diagram of the middle frame 204 shown in FIG. 6 from another angle. FIG. 8 is a partial sectional view of an embodiment of the middle frame 204 at the section line B-B shown in FIG. 6.

[0098] As shown in FIGS. 4 to 7, the middle frame 204 can include a side wall 2041, a front wall 2042, and an ear portion 2043. The front wall 2042 of the middle frame 204 can be fixedly connected to the side wall 2041 of the middle frame 204. The back cover 205 can be connected to an end of the side wall 2041 of the middle frame 204 away from the front wall 2042.

[0099] Exemplarily, the side wall 2041 of the middle frame 204 can be substantially annular. The side wall 2041 of the middle frame 204 can have an inner side surface 2044 and an outer side surface 2045. The inner side surface 2044 and the outer side surface 2045 are oppositely arranged. The inner side surface 2044 faces the accommodation space 40. Exemplarily, the front wall 2042 of the middle frame 204 can participate in constituting the front wall 201 of the housing 20. The side wall 2041 of the middle frame 204 can participate in constituting the side wall 202 of the housing 20. The back cover 205 can participate in constituting the back wall 203 of the housing 20.

[0100] Exemplarily, the side wall 2041 of the middle frame 204 can be in a circular ring shape as shown in FIG. 5. In other embodiments, the side wall 2041 of the middle frame 204 can also be in a plurality of ring shapes such as a runway shape, a quadrilateral shape, a triangular shape, etc., which are not limited in the present application. It can be understood that the shape of the screen 10 and the shape of the back cover 205 can be adjusted according to the shape of the middle frame 204. The shape of the screen 10 is not limited in the present application.

[0101] In some embodiments, the ear portion 2043 can be fixedly connected to the outer side 2045 of the side wall 2041 of the middle frame 204. The ear portion 2043 can be used to connect the watchband 200 (as shown in FIG. 2).

[0102] In some embodiments, the housing 20 can further include a boss 206. The boss 206 can be fixedly connected to the inner side of the side wall 202 of the housing 20 (the boss 206 and the side wall 202 are schematically distinguished by a dashed line in FIG. 4). The inner side of the side wall 202 of the housing 20 refers to the side of the side wall 202 of the housing 20 facing the accommodation space 40. The direction from the inner side to the outer side refers to the direction of the accommodation space 40 facing the outer side of the side wall 202 of the housing 20. Exemplarily, the boss 206 can be fixedly connected to the inner side 2044 of the side wall 2041 of the middle frame 204.

[0103] In some embodiments, the boss 206 and the side wall 202 of the housing 20 can be an integrally formed structure. In this way, the connection reliability between the boss 206 and the side wall 202 is better. In other embodiments, the boss 206 and the side wall 202 can also be fixedly connected by means of gluing, welding, etc.

[0104] In some embodiments, the side wall 202 of the housing 20 can be provided with a relief groove 207. The opening of the relief groove 207 can face the inner side of the side wall 202 of the housing 20. Exemplarily, the relief groove 207 can be located on the middle frame 204. The opening of the relief groove 207 can be located on the inner side 2044 of the side wall 2041 of the middle frame 204.

[0105] In some embodiments, the side wall 2041 of the middle frame 204, the front wall 201 and the ear portion 2043 can be an integral structure. In other embodiments, the side wall 2041 of the middle frame 204, the front wall 201 and the ear portion 2043 can also be separately prepared and then fixedly connected by means of gluing, welding, etc.

[0106] In some embodiments, the cover plate 1 can be at least partially located on the inner side of the side wall 202 of the housing 20 and oppositely arranged to the boss 206 in the first direction. The inner side of the side wall 202 of the housing 20 refers to the side of the side wall 202 of the housing 20 facing the accommodation space 40.

[0107] FIG. 9 is a partial cross-sectional view of an embodiment of the electronic device 1000 shown in FIG. 2 at the cross-sectional line C-C.

[0108] As shown in FIGS. 4 and 9, the screen 10 is mounted to the housing 20. Exemplarily, the cover plate 1 can be mounted to the front wall 201 of the housing 20.

[0109] In some embodiments, the outer edge 401 of the electrical connection assembly 4 is flush with the outer edge 101 of the cover plate 1 (as shown in FIG. 4), or the outer edge 401 of the electrical connection assembly 4 is at least partially located outside the cover plate 1 (as shown in FIG. 9). Herein, the outer edge 401 of the electrical connection assembly 4 refers to the side of the electrical connection assembly 4 away from the side 23 of the display assembly 2. The outer edge 101 of the cover plate 1 refers to the peripheral edge of the cover plate 1. Exemplarily, the projection of the outer edge 401 of the electrical connection assembly 4 on a reference plane in a first direction is a first projection, the projection of the outer edge 101 of the cover plate 1 on the reference plane in the first direction is a second projection, and the projection of the center of the cover plate 1 on the reference plane in the first direction is a third projection. The first direction is the thickness direction of the cover plate 1 (for example, the first direction and the Z-axis direction are parallel in the drawings). The reference plane is perpendicular to the first direction. The outer edge 401 of the electrical connection assembly 4 is flush with the outer edge 101 of the cover plate 1 refers to that the distance between the first projection and the third projection is equal to the distance between the second projection and the third projection. The outer edge 401 of the electrical connection assembly 4 is located outside the cover plate 1 refers to that the distance between the first projection and the third projection is greater than the distance between the second projection and the third projection.

[0110] It can be understood that, by setting the outer edge 401 of the electrical connection assembly 4 flush with the outer edge 101 of the cover plate 1, or by setting the outer edge 401 of the electrical connection assembly 4 at least partially outside the cover plate 1, the mounting clearance between the electrical connection assembly 4 and the housing 20 can be located outside the screen 10, i.e., the projection of the clearance on the reference plane in the first direction and the projection of the screen 10 on the reference plane in the first direction are staggered, which is beneficial to reduce the “black border” of the screen 10, improve the screen-to-body ratio of the electronic device 1000, and improve the user experience. In addition, in the first direction, the part of the outer edge 101 of the cover plate 1 opposite to the electrical connection assembly 4 can be staggered with the housing 20, and the other part of the outer edge 101 of the cover plate 1 is used to fixedly connect the housing 20. In this way, the bonding width of the cover plate 1 at this position can be reduced, and the “black border” width can be further reduced.

[0111] In some embodiments, the projection of the front wall 201 of the housing 20 on the electrical connection assembly 4 in the first direction partially overlaps the electrical connection assembly 4. In this way, the electrical connection assembly 4 can be partially located inside the front wall 201 of the housing 20, where the inside of the front wall 201 refers to the side of the front wall 201 facing the accommodation space 40. The clearance gap between the electrical connection assembly 4 and the housing 20 can further reduce the width of the "black border" by the overlapping part of the front wall 201 in the first direction.

[0112] For example, the screen 10 can be inserted into the lower part of the front wall 201 of the housing 20 (i.e., the side of the front wall 201 close to the accommodation space 40) in a slanted manner.

[0113] For example, the opening of the clearance groove 207 of the housing 20 can face the side 23 of the display assembly 2. The electrical connection assembly 4 can be partially located in the clearance groove 207. It can be understood that by arranging the clearance groove 207 such that the electrical connection assembly 4 is partially located in the clearance groove 207, the space 70 in the clearance groove 207 can serve as a clearance gap between the electrical connection assembly 4 and the housing 20, reducing the risk of collision between the electrical connection assembly 4 and the housing 20 during the installation of the screen 10.

[0114] FIG. 10 is a partial cross-sectional view of an embodiment of the electronic device 1000 shown in FIG. 2 at the cross-sectional line D-D.

[0115] As shown in FIGS. 4, 9, and 10, there is a gap 50 between the cover plate 1, the display assembly 2, and the side wall 202 of the housing 20. The electronic device 1000 can further include a waterproof ring 30, which can fill the gap 50. The waterproof ring 30 can be used to seal the gap 50 between the cover plate 1, the display assembly 2, and the housing 20, preventing external water vapor from entering the accommodation space 40 through the gap 50 between the screen 10 and the housing 20, causing the devices in the accommodation space 40 to fail and the electronic device 1000 to malfunction.

[0116] For example, the waterproof ring 30 can include a first portion 31 and a second portion 32 connected in a circumferential direction. The first portion 31 is connected to the electrical connection assembly 4. It can be understood that the part of the waterproof ring 30 connected to the electrical connection assembly 4 is the first portion 31.

[0117] In some embodiments, the first portion 31 and the second portion 32 can be made of different materials. For example, the material used for the first portion 31 can include glue. The glue can be glue (with flowability between solidification) or glue film (solid with adhesive ability). It can be understood that the material used for the first portion 31 can include glue, and the first portion 31 can have adhesive ability, which can be used to bond the screen 10 and the shell 20, further strengthening the connection strength between the screen 10 and the shell 20. The risk of cracking of the screen 10 and the shell 20 near the electrical connection assembly 4 is reduced.

[0118] It can be understood that the material used for the first portion 31 can be 100% glue, or part of glue and part of other additives to enhance the physical properties (such as corrosion resistance, etc.) of the first portion 31. For example, the content of glue in the material used for the first portion 31 is greater than 80%. In this way, the adhesive ability of the first portion 31 is better.

[0119] For example, the glue can be heat-curable glue, moisture-curable glue, ultraviolet-curable glue, etc. From the chemical composition, the heat-curable glue can be epoxy-based glue; the ultraviolet-curable glue is acrylic-based glue; and the moisture-curable glue can be polyurethane glue. For example, the glue film can be acrylic-based glue.

[0120] In some embodiments, the first portion 31 can be formed by processes such as lower temperature vacuum potting (LTVP), glue filling, etc.

[0121] In some embodiments, when the first portion 31 is formed, a support mold can be added under the middle frame 204, so as to control the morphology of the first portion 31 after formation.

[0122] In some embodiments, when the screen 10 and the shell 20 are assembled, the screen 10 and the middle frame 204 can be assembled first, the first portion 31 can be prepared by glue filling in the containing space 40, and after the waterproof ring 30 is prepared, the rear cover 205 is assembled.

[0123] In some embodiments, the material used for the second portion 32 can include plastic. For example, polyethylene (PE), polyethylene terephthalate (PET), etc. high molecular plastic, or silicone, rubber, etc. For example, the second portion 32 can be formed by injection molding process.

[0124] In some embodiments, the electrical connection assembly 4 includes a bent portion 402 which can enclose a space 70 with the side surface 23 of the display assembly 2. A portion of the waterproof ring 30 can be filled in the space 70. In this way, the waterproof ring 30 can support the bent portion 402 of the electrical connection assembly 4 and better seal water.

[0125] In some embodiments, the electronic device 1000 further includes an adhesive layer 80 fixedly connected between the second portion 32 of the waterproof ring 30 and the housing 20. It can be understood that, by providing the adhesive layer 80, the connection strength between the second portion 32 of the waterproof ring 30 and the housing 20 can be enhanced, and the risk of a gap between the waterproof ring 30 and the housing 20 can be reduced, thereby reducing the risk of water entering the electronic device 1000. For example, the adhesive layer 80 can be a double-sided adhesive tape or other adhesive material.

[0126] For example, the adhesive layer 80 can be fixedly connected between the side wall 202 of the housing 20 and the second portion 32 of the waterproof ring 30, and / or the adhesive layer 80 can be fixedly connected between the boss 206 and the second portion 32 of the waterproof ring 30. The connection between the boss 206 and the adhesive layer 80 is shown in the figures.

[0127] It can be understood that, by fixing the adhesive layer 80 between the boss 206 and the second portion 32 of the waterproof ring 30, the bonding area between the waterproof ring 30 and the housing 20 can be further increased, and the risk of the waterproof ring 30 and the housing 20 being pulled apart can be reduced, thereby improving the waterproof reliability.

[0128] In other embodiments, the waterproof ring 30 can also be partially filled between the cover plate 1 and the front wall 201.

[0129] In some embodiments, the same parts as in the previous embodiments will not be described again. FIG. 11 is a partial cross-sectional view of another embodiment of the electronic device 1000 shown in FIG. 2 at the cross-sectional line E-E. FIG. 12 is a partial cross-sectional view of another embodiment of the electronic device 1000 shown in FIG. 2 at the cross-sectional line F-F.

[0130] As shown in FIGS. 3, 11 and 12, the material of the second portion 32 of the waterproof ring 30 can also include glue. For example, the glue can be glue (solidified between flows) or adhesive film (solid with adhesive ability). It can be understood that, by using glue in the second portion 32, the second portion 32 can have adhesive ability and can be used to bond the screen 10 and the housing 20, thereby further enhancing the connection strength between the screen 10 and the housing 20. The screen 10 can be less likely to be pulled away from the housing 20 under mechanical force, and the waterproof reliability of the waterproof ring 30 is improved.

[0131] Exemplarily, the glue can be a heat-curing glue, a moisture-curing glue, an ultraviolet-curing glue, or the like. In terms of chemical composition, the heat-curing glue can be an epoxy-based glue; the ultraviolet-curing glue can be an acrylic-based glue; and the moisture-curing glue can be a polyurethane-based glue. Exemplarily, the glue film can be an acrylic-based glue.

[0132] Exemplarily, the second part 32 can be formed by a dispensing or pouring process. It can be understood that the dispensing or pouring process has a lower cost than the injection molding process, and the second part 32 of the waterproof ring 30 is formed by the dispensing or pouring process, which is conducive to reducing the manufacturing cost of the waterproof ring 30.

[0133] It can be understood that the material used by the first part 31 of the waterproof ring 30 and the material used by the second part 32 can be the same or different.

[0134] Exemplarily, the first part 31 and the second part 32 can be an integrally formed structural member. The integration of the two components by the integrally formed process means that one of the two components is connected with the other component during the formation of the component, and the two components do not need to be connected together by reprocessing (such as bonding, welding, buckling connection, screw connection). For example, the first part 31 and the second part 32 can be integrally formed by a low-temperature vacuum pouring technology (LTVP).

[0135] In other embodiments, the first part 31 and the second part 32 can be respectively formed by two processes. The present application does not make any limitation.

[0136] FIG. 13 is a structural schematic diagram of an embodiment of the middle frame 204 and the flexible member 90 shown in FIG. 2.

[0137] As shown in FIG. 13, the cover plate 1 is at least partially located inside the sidewall 202 and is arranged opposite to the boss 206 in the first direction. It can be understood that the cover plate 1 is at least partially located inside the sidewall 202, which avoids the display assembly 2 from being exposed to the outside, and can better protect the display assembly 2. By arranging the boss 206, the boss 206 can be used as a positioning structure in the Z-axis direction when assembling the screen 10 and the housing 20, which is used to confirm the position of the screen 10 relative to the housing 20, and reduces the use of molds. In addition, the boss 206 can also increase the connection area between the screen 10 and the housing 20.

[0138] In some embodiments, the electronic device 1000 can further comprise a flexible member 90. The flexible member 90 can be located between the boss 206 and the cover plate 1. Exemplarily, the display assembly 2 of the screen 10 is located opposite to the boss 206 in the first direction. The flexible member 90 can be located between the display assembly 2 and the boss 206. It can be understood that the flexible member 90 can be used to connect the gap 50 and the accommodation space 40, so that the screen 10 and the boss 206 are at least partially spaced apart, which can serve as a path for dispensing or pouring glue.

[0139] Exemplarily, the second part 32 of the waterproof ring 30 can be partially located between the boss 206 and the screen 10 (as shown in FIG. 12). In this way, compared with the scheme in which the waterproof ring 30 is only arranged between the screen 10 and the sidewall 202 of the housing 20, the present embodiment can further increase the bonding area between the waterproof ring 30 and the housing 20, reduce the risk of the waterproof ring 30 and the housing 20 being pulled apart, and improve the waterproof reliability. In addition, under the same connection strength, the second part 32 of the waterproof ring 30 can be partially located between the boss 206 and the screen 10, which can reduce the volume of the waterproof ring 30 between the screen 10 and the sidewall 202 of the housing 20, and the width of the gap 50 in the second direction can be smaller, which can further reduce the width of the "black border".

[0140] In some embodiments, the flexible member 90 has flexibility. When the screen 10 is assembled to the housing 20, the relative positions of the screen 10 and the housing 20 are fixed by pressure from a mold, and the flexible member 90 can balance the pressure around the screen by deforming, so that the levelness of the screen 10 is good, and the profile of the waterproof ring 30 in the gap 50 is also well controlled. In other embodiments, the waterproof ring 30 can use glue with a well-controlled profile, so that the flexible member 90 can not be arranged. More glue is poured in, so that the waterproof ring 30 can fill the gap 50.

[0141] In some embodiments, the number of flexible members 90 can be multiple, and the multiple flexible members 90 are arranged in the circumferential direction of the housing 20. Exemplarily, the number of flexible members 90 can be even, and two flexible members 90 form a group, which is symmetrical about the central axis of the housing 20.

[0142] In some embodiments, the preparation process of the waterproof ring 30 can comprise: pouring glue from the position of the glue pouring path formed by the screen 10 being lifted by the flexible member 90 after the screen 10 is obliquely assembled to the housing 20, vacuumizing the outer side of the screen 10, and controlling the pressure, so that the glue can fill the gap 50. The outer side of the screen 10 refers to the side of the screen 10 away from the accommodation space 40.

[0143] In some embodiments, the waterproof ring 30 can be glued first in the manufacturing process, and then the screen 10 is assembled to the housing 20. In this way, the shape of the glue is easier to control, and the excess glue can be removed later.

[0144] In some embodiments, the waterproof ring 30 can be glued multiple times on the housing 20 in the manufacturing process, and then the screen 10 is assembled to the housing 20. The glue can overflow into the gap 50 between the side surface 23 of the screen 10 and the housing 20 by pressure control.

[0145] In some embodiments, the waterproof ring 30 can be glued on the screen 10 and the housing 20 respectively in the manufacturing process, and then the screen 10 is assembled to the housing 20.

[0146] In some embodiments, when gluing on the housing 20, the side wall 202 and the boss 206 of the housing 20 can be glued respectively, and then the screen 10 is installed. In other embodiments, only one of the side wall 202 and the boss 206 of the housing 20 can be glued. The present application does not make any limitation.

[0147] In some embodiments, when gluing on the housing 20, the position of gluing on the housing 20 can be pretreated, for example, the position of gluing on the housing 20 is coated with a surface modifier, so that the polarity of the surface of the housing 20 and the glue is similar. In this way, it is beneficial to the adhesion of the glue on the housing 20.

[0148] In some embodiments, the same parts as those shown in the previous embodiments will not be described again. FIG. 14 is a partial cross-sectional view of another embodiment of the electronic device 1000 shown in FIG. 2 at the cross-sectional line E-E. FIG. 15 is a structural schematic view of another embodiment of the middle frame 204 shown in FIG. 2.

[0149] As shown in FIGS. 14 and 15, the boss 206 can be provided with a groove 2061. The opening of the groove 2061 can be located on the upper surface 2062 and the inner side surface 2063 of the boss 206. The screen 10 can be fixedly connected to the upper surface 2062 of the boss 206. The groove 2061 can communicate the accommodation space 40 and the gap 50. The waterproof ring 30 can be located partially in the groove 2061. The upper surface 2062 of the boss 206 refers to the side surface of the boss 206 facing the screen 10. The inner side surface 2063 of the boss 206 refers to the side surface of the boss 206 facing the accommodation space 40. It can be understood that by providing the groove 2061, the groove 2061 can communicate the accommodation space 40 and the gap 50, thereby forming a glue filling path. Compared with the scheme of providing the flexible piece 90, the scheme of providing the groove 2061 is beneficial to simplifying the assembly steps and speeding up the production efficiency.

[0150] In some embodiments, the same parts as those shown in the foregoing embodiments are not repeated. FIG. 16 is a partial cross-sectional view of the electronic device 1000 shown in FIG. 2 in another embodiment at the cross-sectional line C-C.

[0151] As shown in FIG. 16, the second part 32 of the waterproof ring 30 can adopt a glue film. The shape of the glue film can match the gap 50 between the screen 10 and the housing 20. For example, the cross section of the glue film can be an "L"-shaped special-shaped glue film as shown in FIG. 17. In other embodiments, the cross section of the second part 32 can also be "I"-shaped.

[0152] For example, a part of the second part 32 of the waterproof ring 30 is fixedly connected between the sidewall 202 of the housing 20 and the screen 10, and a part of the second part 32 of the waterproof ring 30 is fixedly connected between the boss 206 and the screen 10. In other embodiments, the second part 32 of the waterproof ring 30 can also be arranged only between the sidewall 202 of the housing 20 and the screen 10.

[0153] It can be understood that the scheme of adopting the glue film for the second part 32 instead of glue pouring and glue dispensing has good thickness consistency of the glue film, and the uniformity is better controlled than glue dispensing. In addition, if the glue film fails to be bonded with the middle frame 204, the glue film can be reworked like a conventional glue dispensing process, and the cost is low. Compared with the injection molding process, the cost of the screen 10 is also lower than the cost of the whole waterproof ring 30 formed by the LTVP.

[0154] In some embodiments, the material adopted by the second part 32 of the waterproof ring 30 can include glue material and pressure-sensitive material. In this way, during the assembly of the screen 10 and the housing 20, a certain pressure is applied to the screen 10 and the housing 20, so that the second part 32 of the waterproof ring 30 can be better formed and fill the gap 50.

[0155] In some embodiments, the same parts as those shown in the foregoing embodiments are not repeated. FIG. 17 is a partial cross-sectional view of the electronic device 1000 shown in FIG. 2 in another embodiment at the cross-sectional line C-C. FIG. 18 is a partial cross-sectional view of the electronic device 1000 shown in FIG. 2 in another embodiment at the cross-sectional line C-C.

[0156] It can be understood that the electrical connection assembly 4 can adopt a single structure as shown in the foregoing embodiments, or can adopt a plurality of electrical connection assemblies in combination as shown in FIGS. 17 and 18.

[0157] Exemplarily, the electric connection assembly 4 can include a first electric connection piece 41 and a second electric connection piece 42. One end of the first electric connection piece 41 is electrically connected to the display assembly 2, the other end of the first electric connection piece 41 is electrically connected to one end of the second electric connection piece 42, and the other end of the second electric connection piece 42 is electrically connected to the driving assembly 3. The first electric connection piece 41 contacts the side surface 23 of the display assembly 2, and the material of the first electric connection piece 41 can be conductive paste.

[0158] It can be understood that the first electric connection piece 41 can be conductive paste, which has fluidity before solidification, can better adapt to the shape of the side surface 23 of the display assembly 2, so as to realize the electrical connection between the driving assembly 3 and the display assembly 2, and can reduce the risk of the electric connection assembly 4 being separated from the display assembly 2 and the driving assembly 3 due to excessive stress after bending. The electric connection assembly 4 does not need to be bent, and the connection reliability between the electric connection assembly 4 and the display assembly 2 and the driving assembly 3 is higher, and the electrical connection is more reliable. In the scheme of the embodiment, the electric connection assembly 4 directly contacts the side surface 23 of the display assembly 2, and there is no gap between the electric connection assembly 4 and the side surface 23 of the display assembly 2. The “black border” in the scheme of the present application can be smaller. When the screen 10 is installed on the shell 20, the angle of the screen 10 in the oblique insertion process can be reduced, or the screen 10 does not need to be obliquely inserted and can be installed on the shell 20.

[0159] Exemplarily, the material of the first electric connection piece 41 can be conductive silver paste or conductive glue.

[0160] In some embodiments, the shell 20 can also not be provided with a avoiding groove (as shown in FIG. 17), so that the shell 20 does not need to sacrifice the thickness, and the reliability is higher.

[0161] The present application introduces several structures of electronic devices 1000 through the drawings. The electronic device 1000 can include a shell 20 and a screen 10. The screen 10 includes a cover plate 1 and a display assembly 2. The cover plate 1 is fixed to the shell 20 and surrounds a containing space 40 with the shell 20. The display assembly 2 is fixedly connected to the cover plate 1 and is located in the containing space 40. The screen 10 further includes a driving assembly 3 and an electric connection assembly 4. The driving assembly 3 and the electric connection assembly 4 are located in the containing space 40. The driving assembly 3 is fixedly connected to the side of the display assembly 2 away from the cover plate 1. One end of the electric connection assembly 4 is electrically connected to the display assembly 2, and the other end of the electric connection assembly 4 is electrically connected to the driving assembly 3. The electric connection assembly 4 is at least partially located on the side surface 23 of the display assembly 2. The outer edge 401 of the electric connection assembly 4 is flush with the outer edge 101 of the cover plate 1, or the outer edge 401 of the electric connection assembly 4 is at least partially located on the outer side of the cover plate 1.

[0162] It can be understood that the outer edge 401 of the electrical connection assembly 4 is arranged flush with the outer edge 101 of the cover plate 1, or at least partially arranged outside the cover plate 1, the mounting clearance between the electrical connection assembly 4 and the shell 20 can be located outside the screen 10, that is, the projection of the clearance on the reference surface in the first direction is offset from the projection of the screen 10 on the reference surface in the first direction, which is beneficial to reduce the "black border" of the screen 10, improve the screen-to-body ratio of the electronic device 1000, and improve the user experience. In addition, in the first direction, the part of the outer edge 101 of the cover plate 1 arranged opposite to the electrical connection assembly 4 can be arranged offset from the shell 20 in the first direction, and the other part of the outer edge 101 of the cover plate 1 is used to fixedly connect the shell 20. In this way, the bonding width of the cover plate 1 at this position can be reduced, and the "black border" width can be further reduced.

[0163] Exemplarily, compared with the conventional technical solution (for example, as shown in FIG. 1), the electronic device 1000 adopts the technical solution of the present application, and the "black border" width on the side where the electrical connection assembly 4 is located can be reduced by about 0.3mm-1mm. When the electronic device 1000 is a wearable device, the area of the screen 10 is relatively small, so the width of the "black border" is reduced, and the screen-to-body ratio can be significantly improved, and the user experience can be better improved.

[0164] It can be understood that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and any combination of features in different embodiments is also within the protection scope of the present application, that is, the above-described multiple embodiments can also be combined as needed.

[0165] It can be understood that all the above-mentioned drawings are exemplary drawings of the present application, and do not represent the actual size of the product. The size ratio relationship between the components in the drawings is not limited to the actual product of the present application.

[0166] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
