Description

Display module and electronic device

[0001] The present application claims priority to the Chinese patent application No. 202410732440.X, filed on June 6, 2024, and entitled "Display module and 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, in particular to a display module and an electronic device. BACKGROUND

[0003] With the continuous development of science and technology, electronic devices such as mobile phones are widely used in people's daily life and work, and have become an indispensable daily necessity for people. At present, electronic devices include many functional components such as display modules, circuit boards, and batteries. These functional components occupy a large internal space inside the electronic device, which is not conducive to the lightweight design of the electronic device. SUMMARY

[0004] The present application provides a display module and an electronic device, which are used to improve the utilization rate of the internal space of the electronic device and realize the lightweight design of the electronic device.

[0005] In a first aspect, the present application provides a display module, comprising a display panel, a connecting circuit board, and a first electronic device.

[0006] The display panel comprises a display part and a connecting part. The display part comprises a display surface and a non-display surface. The display surface and the non-display surface are arranged opposite to each other. The display surface is used to display information such as images or text. The connecting part is arranged on the non-display surface and connected with the display part.

[0007] It should be noted that the connecting part arranged on the non-display surface means that the connecting part is arranged on the side of the non-display surface of the display part. The connecting part can be directly arranged on the non-display surface, or indirectly arranged on the non-display surface, for example, the connecting part can be arranged on the non-display surface through an adhesive layer structure, and similar descriptions in the following can be understood in the same way.

[0008] The connecting circuit board comprises a main body part and a first edge part. Both the main body part and the first edge part are arranged on the non-display surface. The main body part is located at the middle position of the display module and arranged adjacent to the connecting part and connected with the connecting part. The first edge part is located at the edge position of the display module and located on the same side of the connecting part and the main body part, and connected with the main body part. The first edge part extends from the edge of the main body part to the direction of the connecting part, and protrudes toward the edge of the main body part relative to the connecting part. Wherein, along the width direction of the connecting part and the main body part, the first edge part is located on one side of the connecting part and the main body part.

[0009] It should be noted that the main body part is arranged adjacent to the connecting part, which means that the two are arranged on the non-display surface and do not completely overlap.

[0010] The first electronic device is arranged on the side of the first edge part away from the non-display surface.

[0011] It should be noted that functional components such as batteries and heat sinks of electronic devices are often arranged in the middle position of the electronic device, so that the middle position of the electronic device is prone to device stacking, resulting in a relatively cramped thickness space in the middle position of the electronic device, while the thickness space of the edge position of the electronic device is relatively spacious.

[0012] In the display module shown in the present application, the first electronic device is arranged in the first edge part, which can reduce the thickness of the position where the main body part of the connecting circuit board is located in the display module, i.e., the middle position of the display module. When the display module is used in an electronic device, not only can the thickness space occupied by the display module in the middle position of the electronic device be reduced, but also a larger thickness space can be reserved for functional components located in the middle position of the electronic device, avoiding the stacking of electronic devices and these functional components in the thickness direction, and the first electronic device can also be accommodated in the position corresponding to the first edge part in the shell of the electronic device, increasing the spatial multiplexing of the display module and the shell in the thickness direction, improving the spatial utilization rate of the electronic device in the thickness direction, and realizing the lightweight design of the electronic device.

[0013] The main body part includes a main body portion and a first end portion. The main body portion is arranged spaced apart from the connecting part. The first end portion is connected to the edge of the main body portion facing the connecting part and connected to the connecting part to form a binding area. Along the length direction of the first end portion, the first edge part is connected to one side of the main body portion and extends from the main body portion toward the connecting part and protrudes relative to the direction of the first end portion toward the connecting part.

[0014] The connecting part includes a third end portion and a fourth end portion. The third end portion is connected to the display part. The fourth end portion is arranged opposite the third end portion and connected to the first end portion to form the binding area.

[0015] In an embodiment, the first edge part is arranged spaced apart from the connecting part to form a first gap. Along the width direction of the binding area, the first gap is located on one side of the binding area. One end of the first gap faces the edge of the display module, and the other end faces the binding area.

[0016] The display module further includes a first sealing glue, and the first sealing glue is arranged in the first gap. The first sealing glue can be connected to the non-display surface, the connecting part and the first edge part to seal the first gap.

[0017] The display module shown in the present application uses the first sealing glue to seal the first gap. In the use process of the display module, when water or other liquids from the outside enter the first gap from the edge of the display module, the first sealing glue can block the liquids, and the liquids cannot flow to the binding area through the first sealing glue, so that corrosion of the liquids to the binding area can be avoided, the waterproof performance of the display module can be improved, and the use reliability of the display module is improved.

[0018] In an implementation mode, the display module further comprises an insulating glue layer, which is arranged on the connecting part and the side of the connecting circuit board away from the non-display surface, and covers at least part of the first gap. The first sealing glue can also be connected with the insulating glue layer.

[0019] It should be noted that since the connecting part of the display panel, the connecting circuit board and the insulating glue layer all have a certain thickness, when the insulating glue layer is attached, it is difficult for the insulating glue layer to fill the first gap, the insulating glue layer cannot completely seal the first gap, and an opening communicating with the first gap will be formed between the insulating glue layer and the non-display surface. In the use process of the display module, water or other liquids from the outside will enter the first gap from the opening between the insulating glue layer and the non-display surface, and then reach the connecting area (i.e. the binding area) of the main body part and the connecting part from the first gap, thereby corroding the display module and reducing the use reliability of the display module, and further reducing the use reliability of the electronic device.

[0020] The display module shown in the present application uses the first sealing glue to seal the first gap. In the use process of the display module, when water or other liquids from the outside enter the first gap from the edge of the display module, the first sealing glue can block the liquids, and the liquids cannot flow to the binding area through the first sealing glue, so that corrosion of the liquids to the binding area can be avoided, the waterproof performance of the display module can be improved, and the use reliability of the display module is improved.

[0021] In an implementation mode, the insulating glue layer also covers at least part of the first electronic device.

[0022] It should be noted that the first electronic device is arranged on the surface of the first edge part away from the non-display surface, and the first electronic device will protrude relative to the first edge part. When the insulating glue layer is attached, the first electronic device will also affect the adhesion of the insulating glue layer and the connecting circuit board, the edge of the insulating glue layer will be raised, and the size of the opening between the insulating glue layer and the non-display surface will be further increased. In the use process of the electronic device, water or other liquids from the outside will enter the first gap from the opening between the insulating glue layer and the non-display surface, and then reach the binding area from the first gap, thereby corroding the display module and reducing the use reliability of the display module, and further reducing the use reliability of the electronic device.

[0023] The display module shown in the present application adopts the first sealing glue to seal the first gap. In the use process of the display module, when water or other liquids from the outside enter the first gap through the opening between the insulating glue layer and the non-display surface of the display module, the first sealing glue can block the liquid, and the liquid cannot flow to the binding area through the first sealing glue, which can prevent the liquid from corroding the binding area, help to improve the waterproof performance of the display module, and further improve the use reliability of the display module.

[0024] In an embodiment, the insulating glue layer is provided with a first through hole penetrating the insulating glue layer along the thickness direction of the insulating glue layer and exposing at least part of the first sealing glue. It should be noted that the first through hole exposes at least part of the first sealing glue, which means that the first through hole exposes at least part of the first sealing glue along the thickness direction of the display module, and similar descriptions hereinafter can be understood in the same way.

[0025] In the assembly process of the display module shown in the present application, the connection circuit board and the display panel are first assembled, then the insulating glue layer is arranged on the side of the connection part and the connection circuit board away from the non-display surface to cover at least part of the connection part, at least part of the connection circuit board and at least part of the first gap, and the first through hole is aligned with the first gap, and finally the first gap is sealed by dispensing glue through the first through hole until the first gap is sealed to form the first sealing glue.

[0026] In an embodiment, the first through hole also exposes at least part of the connection part and at least part of the first edge part. In other words, the size of the first through hole is larger than the size of the first gap, which can ensure that the first sealing glue can completely seal the first gap during dispensing, and ensure the waterproof performance of the display module.

[0027] In an embodiment, the first through hole has a plurality of first through holes, and the plurality of first through holes are arranged at intervals. At least one first through hole exposes at least part of the first sealing glue. The plurality of first through holes can be arranged at intervals along the length direction of the first gap.

[0028] In the display module shown in the present application, a plurality of first sealing glues can be used to seal the first gap, which can improve the sealing effect of the first gap, help to improve the waterproof performance of the display module, and ensure the use reliability of the display module.

[0029] In an embodiment, the insulating glue layer also covers at least part of the first sealing glue.

[0030] In the assembling process of the display module shown in the present application, the first blocking glue is formed by dispensing in the first gap, and then the insulating glue layer is attached, without dispensing the first blocking glue through the first through hole of the insulating glue layer. Not only is the forming process of the first blocking glue simplified, but also a larger operation space can be reserved for forming the first blocking glue, which can ensure that the first blocking glue can completely block the first gap. Moreover, the insulating glue layer does not need to be perforated, which can simplify the preparation process of the display module and help reduce the cost of the display module. Furthermore, under this arrangement, the first blocking glue will not be exposed relative to the insulating glue layer, which can help ensure the flatness of the back of the display module and avoid interference between the display module and the foldable device in subsequent processes, thereby helping to improve the assembly efficiency between the display module and the foldable device.

[0031] In an embodiment, the first blocking glue has a plurality of sub-blocking glues, and the plurality of sub-blocking glues are arranged at intervals. The plurality of sub-blocking glues can be arranged in sequence along the length direction of the first gap.

[0032] In the display module shown in the present application, the first blocking glue is arranged in segments, which not only ensures the waterproof performance of the display module, but also saves the dispensing cost of the display module.

[0033] In an embodiment, the connection circuit board further includes a second edge portion, which is arranged on the non-display surface, connected to the main body portion, and located on the side of the connection portion and the main body portion away from the first edge portion. The second edge portion extends from the edge of the main body portion toward the connection portion. Along the width direction of the connection portion and the main body portion, the second edge portion is located on the other side of the connection portion and the main body portion. That is, along the width direction of the connection portion and the main body portion, the first edge portion and the second edge portion are respectively located on opposite sides of the connection portion and the main body portion.

[0034] The display module further includes a second electronic device, which is arranged on the side of the second edge portion away from the non-display surface.

[0035] In the display module shown in the present application, the second electronic device is arranged on the second edge portion, which can reduce the thickness of the position of the main body portion of the connection circuit board in the display module (i.e., the middle position of the display module). When the display module is used in an electronic device, not only can the thickness space occupied by the display module at the middle position of the electronic device be reduced, but also a larger thickness space can be reserved for functional components located at the middle position of the electronic device, avoiding the stacking of the electronic device and these functional components in the thickness direction. In addition, the second electronic device can be accommodated in the position corresponding to the second edge portion in the shell of the electronic device, increasing the spatial multiplexing of the display module and the shell in the thickness direction, improving the spatial utilization rate of the electronic device in the thickness direction, and realizing the lightweight design of the electronic device.

[0036] The second edge portion is connected to the other side of the main body portion along the length direction of the first end portion, extends from the main body portion toward the connecting portion, and protrudes toward the direction in which the connecting portion is located relative to the first end portion.

[0037] In an embodiment, the second edge portion is spaced apart from the connecting portion to form a second gap. The second gap is located on the other side of the binding area along the length direction of the binding area. One end of the second gap is toward the edge of the display module, and the other end is toward the binding area.

[0038] The display module further includes a second sealing glue, and the second sealing glue is arranged in the second gap. The second sealing corner can be connected to the non-display surface, the connecting portion, and the second edge portion to seal the second gap.

[0039] In the display module shown in the present application, the first sealing glue and the second sealing glue are used to seal the first gap and the second gap located on the opposite sides of the binding area, respectively. In the use process of the display module, the first sealing glue and the second sealing glue can respectively block the water and other liquids from the outside from flowing to the binding area through the first gap and the second gap, thereby avoiding the corrosion of the water and other liquids from the outside to the binding area, improving the waterproof performance of the display module, and improving the use reliability of the display module.

[0040] In an embodiment, the insulating glue layer also covers at least part of the second gap. The second sealing glue can also be connected to the insulating glue layer.

[0041] It should be noted that since the connecting portion of the display panel, the connecting circuit board, and the insulating glue layer all have a certain thickness, when the insulating glue layer is attached, it is difficult for the insulating glue layer to fill the second gap, and the insulating glue layer cannot completely seal the second gap. An opening is formed between the insulating glue layer and the non-display surface, which is in communication with the second gap. In the use process of the display module, the water and other liquids from the outside can enter the second gap from the opening between the insulating glue layer and the non-display surface, and then reach the connecting area (i.e., the binding area) of the main body portion and the connecting portion from the second gap, thereby corroding the display module, reducing the use reliability of the display module, and further reducing the use reliability of the electronic device.

[0042] The display module shown in the present application uses the second sealing glue to seal the second gap. In the use process of the display module, when the water and other liquids from the outside enter the second gap from the edge of the display module, the second sealing glue can block the liquids, and the liquids cannot flow to the binding area through the second sealing glue, thereby avoiding the corrosion of the liquids to the binding area, helping to improve the waterproof performance of the display module, and further improving the use reliability of the display module.

[0043] In an embodiment, the insulating glue layer also covers at least part of the second electronic device.

[0044] It should be noted that the second electronic device is arranged on the surface of the second edge portion away from the non-display surface, and the second electronic device protrudes relative to the second edge portion. When the insulating adhesive layer is attached, the second electronic device also affects the attachment of the insulating adhesive layer to the connecting circuit board, the edge of the insulating adhesive layer is raised, and the opening size between the insulating adhesive layer and the non-display surface is further increased. During use of the electronic device, water or other liquids from the outside can enter the second gap from the opening between the insulating adhesive layer and the non-display surface, and then reach the bonding area from the first gap, thereby corroding the display module and reducing the use reliability of the display module, and further reducing the use reliability of the electronic device.

[0045] The display module shown in the present application uses a second sealing adhesive to seal the second gap. During use of the display module, when water or other liquids from the outside enter the second gap from the opening between the insulating adhesive layer and the non-display surface, the second sealing adhesive can block the liquids, and the liquids cannot flow to the bonding area through the second sealing adhesive, thereby preventing corrosion of the bonding area by the liquids, improving the waterproof performance of the display module, and further improving the use reliability of the display module.

[0046] In one embodiment, the insulating adhesive layer is provided with a second through hole, the second through hole penetrates the insulating adhesive layer along the thickness direction of the insulating adhesive layer, and at least part of the second sealing adhesive is exposed.

[0047] During assembly of the display module shown in the present application, the connecting circuit board and the display panel are first assembled, then the insulating adhesive layer is arranged on the connecting portion and the side of the connecting circuit board away from the non-display surface to cover at least part of the connecting portion, at least part of the connecting circuit board, and at least part of the second gap, the second through hole is aligned with the second gap, and finally glue is dispensed into the second gap through the second through hole until the second gap is sealed to form the second sealing adhesive.

[0048] In one embodiment, the second through hole also exposes at least part of the connecting portion and at least part of the second edge portion. In other words, the size of the second through hole is greater than the size of the second gap, which can ensure that the second sealing adhesive can completely seal the second gap during dispensing, and improve the waterproof performance of the display module.

[0049] In one embodiment, the second through hole has a plurality of second through holes, and the plurality of second through holes are arranged at intervals. At least one second through hole exposes at least part of the second sealing adhesive. The plurality of second through holes can be arranged at intervals along the length direction of the second gap.

[0050] In the display module shown in the present application, a plurality of second sealing adhesives can be used to seal the second gap, which can improve the sealing effect of the second gap, improve the waterproof performance of the display module, and ensure the use reliability of the display module.

[0051] In one embodiment, the insulating adhesive layer also covers at least part of the second sealing adhesive.

[0052] In the assembling process of the display module shown in the present application, the second blocking glue is formed by dispensing in the second gap, and then the insulating glue layer is attached. The second gap does not need to be dispensed through the second through hole of the insulating glue layer. Not only is the forming process of the second blocking glue simplified, but also a larger operation space can be reserved for forming the second blocking glue, which can ensure that the second blocking glue can completely block the second gap. Moreover, the insulating glue layer does not need to be perforated, which can simplify the preparation process of the display module and help to reduce the cost of the display module. Furthermore, under this arrangement, the second blocking glue will not be exposed relative to the insulating glue layer, which helps to ensure the flatness of the back of the display module and can avoid the problem of interference between the display module and the foldable device in subsequent processes, which helps to improve the assembly efficiency between the display module and the foldable device.

[0053] In an embodiment, the second blocking glue has a plurality of sub-blocking glues, and the plurality of sub-blocking glues are arranged at intervals. The plurality of sub-blocking glues can be arranged in sequence along the length direction of the second gap.

[0054] In the display module shown in the present application, the second blocking glue is arranged in sections, which not only ensures the waterproof performance of the display module, but also saves the dispensing cost of the display module.

[0055] In a second aspect, the present application provides an electronic device, which includes a housing and any of the display modules described above, and the display module is arranged in the housing. The housing is provided with a first avoiding slot, and the opening of the first avoiding slot is located on the surface of the housing facing the display module. The first avoiding slot is arranged opposite to the first electronic device.

[0056] In the electronic device shown in the present application, the display module arranges the first electronic device at the first edge part, which can reduce the thickness of the position where the main part of the connecting circuit board is located in the display module (i.e. the middle position of the display module). Not only can it reduce the thickness space occupied by the display module at the middle position of the electronic device, but also it can reserve a larger thickness space for the functional components located at the middle position of the electronic device, avoid the stacking of the electronic device and these functional components in the thickness direction, and also arrange the first avoiding slot on the housing to avoid the first electronic device, to increase the space multiplexing of the display module and the housing in the thickness direction, improve the space utilization of the electronic device in the thickness direction, and realize the lightweight design of the electronic device.

[0057] In an embodiment, the electronic device further includes a battery, and the battery is arranged in the housing. Along the thickness direction of the electronic device, the battery and the main part are stacked. It should be noted that the stacking of the battery and the main part means that the projection of the battery on the connecting circuit board coincides with at least part of the main part, and similar descriptions in the following can be understood in the same way.

[0058] In the electronic device shown in the present application, the battery and the main body part connected to the circuit board are stacked in the thickness direction of the electronic device, and the electronic device arranged at the first edge part of the connected circuit board does not stack in the thickness direction of the electronic device with the battery, which helps to reduce the thickness of the electronic device and achieve the lightweight design of the electronic device.

[0059] In an embodiment, the electronic device further includes a first circuit board arranged in the housing. The first circuit board, the first electronic device and the first edge part are stacked in the thickness direction of the electronic device.

[0060] In the electronic device shown in the present application, the first electronic device and the first edge part are stacked with the first circuit board in the thickness direction of the electronic device, without stacking with the functional components such as the battery in the thickness direction of the electronic device, which helps to reduce the thickness of the electronic device and achieve the lightweight design of the electronic device.

[0061] In an embodiment, the electronic device further includes a first functional module arranged on the first circuit board and staggered with the first electronic device.

[0062] In the electronic device shown in the present application, the first electronic device and the first edge part are stacked with the part of the first circuit board on which no functional module is arranged, which can effectively utilize the empty space on the first circuit board and stack the first electronic device and the first edge part in the thickness direction of the electronic device, increase the spatial multiplexing of the display module and the housing in the thickness direction, improve the spatial utilization of the electronic device in the thickness direction, and achieve the lightweight design of the electronic device.

[0063] In an embodiment, the electronic device includes a first main body, a second main body and a foldable mechanism. The foldable mechanism is connected between the first main body and the second main body. The second main body includes a housing.

The first display part is mounted on the first main body, the second display part is mounted on the second main body, and the foldable part is arranged opposite to the foldable mechanism. The connecting part is arranged between the second display part and the second main body and connected to the end of the second display part away from the foldable mechanism.

[0091] The technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application.

[0092] Please refer to Figs. 1 and 2, Fig. 1 is a schematic view of a structure of a first electronic device 1000 in a folded state provided in the present application, and Fig. 2 is a schematic view of a structure of the electronic device 1000 shown in Fig. 1 in an unfolded state.

[0093] The electronic device 1000 can be a mobile phone, a tablet computer, a personal computer, a multimedia player, an electronic book reader, a notebook computer, a vehicle-mounted device or a wearable device, etc. In the present embodiment, the electronic device 1000 is a foldable mobile phone. That is, the electronic device 1000 is a mobile phone which can be switched between a folded state and an unfolded state.

[0094] In the present embodiment, for the convenience of description, the width direction of the electronic device 1000 shown in Fig. 1 is defined as the X-axis direction, the length direction of the electronic device 1000 is defined as the Y-axis direction, and the thickness direction of the electronic device 1000 is defined as the Z-axis direction. The X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other. For example, the extension direction of the rotation axis of the electronic device 1000 is parallel to the Y-axis direction. That is, the electronic device 1000 can be relatively unfolded or relatively folded around the Y-axis direction.

[0095] It should be noted that the parallel and perpendicular in the present application are relative position relations, which are based on the current process level, not the absolute strict definition in the mathematical sense, and a small amount of deviation is allowed, i.e. approximately parallel and approximately perpendicular. For example, A is parallel to B, which means that A is parallel to B or approximately parallel to B, 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 is perpendicular to B or approximately perpendicular to B, and the included angle between A and B is between 80 degree and 100 degree.

[0096] The electronic device 1000 shown in FIG. 1 is in a folded state. At this time, the electronic device 1000 has a small size along the X-axis direction, and the electronic device 1000 is convenient to carry. The electronic device 1000 shown in FIG. 2 is in an unfolded state. For example, the unfolding angle a of the electronic device 1000 shown in FIG. 2 is 180 degrees. In other words, the electronic device 1000 shown in FIG. 1 is in a flat state. At this time, the electronic device 1000 has a large size along the X-axis direction, and the electronic device 1000 has a large display area.

[0097] It should be noted that the angles illustrated in the present application are allowed to have a small deviation. For example, the unfolding angle a of the electronic device 1000 shown in FIG. 2 is 180 degrees, which means that a can be 180 degrees, or approximately 180 degrees, such as 170 degrees, 175 degrees, 185 degrees, and 190 degrees. The angles illustrated in the following examples can be understood in the same way.

[0098] It should be understood that the electronic device 1000 shown in the present application is a terminal that can be folded once. In other embodiments, the electronic device 1000 can also be a terminal that can be folded multiple times (more than twice). At this time, the electronic device 1000 can include multiple parts, and adjacent two parts can be relatively close to be folded to the electronic device 1000 in a folded state, and adjacent two parts can be relatively away to be unfolded to the electronic device 1000 in an unfolded state.

[0099] The electronic device 1000 includes a foldable device 100 and a display module 200, and the display module 200 is mounted on the foldable device 100. The display module 200 includes a display surface 241 facing away from the foldable device 100, and the display surface 241 is used to display text, images, or video information. In the present embodiment, the display module 200 includes a first display part 210, a second display part 220, and a foldable part 230, and the foldable part 230 is connected between the first display part 210 and the second display part 220.

At this time, the included angle between the first display portion 210 and the second display portion 220, the included angle between the first display portion 210 and the foldable portion 230, and the included angle between the second display portion 220 and the foldable portion 230 are all α, the display module 200 has a large-area display region, realizes large-screen display of the electronic device 1000, and improves the user's use experience.

[0102] It should be understood that the electronic device 1000 shown in the present application adopts an inward folding manner for folding, and when the electronic device 1000 is in the folded state, the display module 200 is located at the inner side of the foldable apparatus 100.

Specifically, the first main body 110a carries the first display portion 210, and the second main body 110b carries the second display portion 220. In other words, the first display portion 210 is mounted on the first main body 110a, and the second display portion 220 is mounted on the second main body 110b. Wherein, the foldable mechanism 120 is arranged opposite to the foldable portion 230.

[0104] The first main body 110a and the second main body 110b can be relatively rotated through the foldable mechanism 120, so that the foldable apparatus 100 is switched between the folded state and the unfolded state. Specifically, the first main body 110a and the second main body 110b can be relatively rotated to be relatively arranged, so that the foldable apparatus 100 is in the folded state, as shown in FIG. 1. At this time, the foldable mechanism 120 is in the folded state. The first main body 110a and the second main body 110b can also be relatively rotated to be relatively unfolded, so that the electronic device 1000 is in the unfolded state, as shown in FIG. 2. At this time, the included angle between the first main body 110a and the second main body 110b is α, and the foldable mechanism 120 is in the unfolded state.

[0105] Please refer to FIG. 3 and FIG. 4, FIG. 3 is a schematic diagram of a partial structure of the second main body 110b of the foldable device 100 in the electronic device 1000 shown in FIG. 2, and FIG. 4 is a schematic diagram of a cross-sectional structure of the second main body 110b shown in FIG. 3 after being cut along I-I. Wherein, cutting along I-I means cutting along the plane where the line I-I is located, and similar descriptions hereinafter can be understood in the same way.

[0106] The second main body 110b includes a shell 111, a battery 112, a circuit board 113, a functional module 114 and a heat sink 115, and the battery 112, the circuit board 113, the functional module 114 and the heat sink 115 are all arranged in the shell 111.

[0107] The shell 111 includes a middle frame 116 and a back cover 117, and the back cover 117 is arranged on the middle frame 116. The middle frame 116 is provided with a mounting groove 1161 and an avoiding groove 1162. The opening of the mounting groove 1161 is located on the bottom surface (not marked in the figure) of the middle frame 116. The mounting groove 1161 is recessed from the bottom surface to the top surface (not marked in the figure) of the middle frame 116 (the positive direction of the Z-axis shown in the figure). The avoiding groove 1162 is located on the side of the middle frame 116 away from the second main body 110b. The opening of the avoiding groove 1162 is located on the top surface of the middle frame 116.

Wherein, the avoiding groove 1162 has two, and the two avoiding grooves 1162 are respectively a first avoiding groove 1162a and a second avoiding groove 1162b. The first avoiding groove 1162a and the second avoiding groove 1162b are arranged at intervals along the length direction (the Y-axis direction shown in the figure) of the middle frame 116.

[0108] It should be noted that the "top" and "bottom" and other orientation words used in the description of the electronic device 1000 in the embodiments of the present application are mainly described based on the orientation of the electronic device 1000 in the drawings, and the "top" is toward the positive direction of the Z-axis, and the "bottom" is toward the negative direction of the Z-axis, which does not limit the orientation of the electronic device 1000 in the actual application scenario.

[0109] In the embodiment, the middle frame 116 is provided with an avoiding protrusion 1163. The avoiding protrusion 1163 is arranged on the groove bottom wall surface (not marked in the figure) of the mounting groove 1161, and protrudes from the groove bottom wall surface of the mounting groove 1161 to the direction away from the top surface of the middle frame 116 (the negative direction of the Z-axis shown in the figure). Wherein, the surface of the avoiding protrusion 1163 away from the groove bottom wall surface of the mounting groove 1161 is located between the groove bottom wall surface of the mounting groove 1161 and the opening of the mounting groove 1161. That is, the avoiding protrusion 1163 does not protrude relative to the opening of the mounting groove 1161. At this time, the avoiding protrusion 1163 can completely reuse the thickness space of the mounting groove 1161, which not only can ensure the strength of the middle frame 116, but also is beneficial to save the internal space of the middle frame 116, improve the utilization rate of the internal space of the middle frame 116, and help to realize the light and thin design of the electronic device 1000.

[0110] Specifically, the avoidance protrusion 1163 is arranged corresponding to the avoidance groove 1162.

That is, the avoidance groove 1162 is recessed from the top surface of the middle frame 116 to the direction of the avoidance protrusion 1163. Specifically, the avoidance protrusion 1163 and the avoidance groove 1162 can be formed at one time. That is, in the forming process of the middle frame 116, the avoidance protrusion 1163 can be formed at the same time as the avoidance groove 1162. Among them, the avoidance protrusion 1163 has two, and the two avoidance protrusions 1163 are respectively the first avoidance protrusion 1163a and the second avoidance protrusion 1163, the first avoidance protrusion 1163a is arranged corresponding to the first avoidance groove 1162a, and the second avoidance protrusion 1163b is arranged corresponding to the second avoidance groove 1162b. In other embodiments, the middle frame 116 can also not be provided with the avoidance protrusion 1163, and the present application does not make specific limitations thereto.

[0111] The battery 112, the circuit board 113 and the functional module 114 are all arranged in the mounting groove 1161, and are all arranged spaced apart from the avoidance protrusion 1163.

Along the length direction of the middle frame 116, the circuit board 113 is located on one side of the battery 112 and is arranged spaced apart from the battery 112 and is arranged spaced apart and opposite to the avoidance protrusion 1163. Among them, the circuit board 113 has two, and the two circuit boards 113 are respectively the first circuit board 113a and the second circuit board 113b. Along the length direction of the middle frame 116, the first circuit board 113a and the second circuit board 113b are respectively located on the opposite sides of the battery 112. The first circuit board 113a is arranged spaced apart and opposite to the first avoidance protrusion 1163a. The second circuit board 113b is arranged spaced apart and opposite to the second avoidance protrusion 1163.

[0112] The functional module 114 is arranged on the side of the circuit board 113 facing the groove bottom wall surface of the mounting groove 1161, and is electrically connected with the circuit board 113. Specifically, along the length direction of the middle frame 116, the functional module 114 is located on one side of the avoidance groove 1162 and the avoidance protrusion 1163, and is arranged spaced apart from the avoidance groove 1162 and the avoidance protrusion 1163. Specifically, the functional module 114 can be a camera module or a speaker module, etc. Among them, the functional module 114 can have four, and the four functional modules 114 can include two first functional modules 114a and two second functional modules 114b. The two first functional modules 114a are both arranged on the first circuit board 113a, and are respectively located on the opposite sides of the first avoidance groove 1162a and the first avoidance protrusion 1163a. The two second functional modules 114b are both arranged on the second circuit board 113b, and are respectively located on the opposite sides of the second avoidance groove 1162b and the second avoidance protrusion 1163b.

[0113] The back cover 117 is arranged on the bottom surface of the middle frame 116, and can cover the opening of the mounting groove 1161, and can cover the battery 112, the circuit board 113 and the functional module 114. The back cover 117 can be arranged on the bottom surface of the middle frame 116 by means of adhesion or welding, or the back cover 117 can be assembled into an integrated structure with the middle frame 116 to ensure the strength of the shell 111.

[0114] The heat dissipation plate 115 is arranged on the top surface of the middle frame 116. In the thickness direction (i.e. the direction of the Z axis in the figure) of the electronic device 1000, the heat dissipation plate 115 is stacked with the battery 112. The heat generated by the battery 112 during operation can be transmitted to the heat dissipation plate 115 through the middle frame 116, and then transmitted to the external environment of the electronic device 1000 through the heat dissipation plate 115, thereby achieving heat dissipation of the battery 112. The heat dissipation plate 115 can be a vapor chamber (VC) plate. In other embodiments, the heat dissipation plate 115 can also be other devices that can play a role in heat dissipation, which is not limited in the present application.

[0117] Please refer to FIG. 7 together, FIG. 7 is a structure schematic diagram of the display panel 240 in the display module 200 shown in FIG. 5.

[0118] The display panel 240 includes a display part 242 and a connection part 243. The display part 242 includes a display surface 241 and a non-display surface 244. The display surface 241 and the non-display surface 244 are arranged opposite to each other along the thickness direction of the display part 242. The display part 242 includes a first display part 210, a second display part 220 and a foldable part 230. The connection part 243 is electrically connected to the display part 242, and is folded relative to the display part 242, and is arranged on the non-display surface 244.

[0119] It should be noted that the connection part 243 is arranged on the non-display surface 244 means that the connection part 243 is arranged on the side where the non-display surface 244 of the display part 242 is located. The connection part 243 can be directly arranged on the non-display surface 244, or the connection part 243 can be indirectly arranged on the non-display surface 244, for example, the connection part 243 can be arranged on the non-display surface through a layer structure such as adhesive, and the like. The similar description hereinafter can be understood in the same way.

[0120] Specifically, the connection part 243 is arranged between the second display part 220 and the second main body 110b, and is connected to one end of the second display part 220 away from the foldable mechanism 120 and the foldable part 230, and is folded relative to the second display part 220. The connection part 243 includes a third end part 245 and a fourth end part 246. The third end part 245 is electrically connected to the display part 242. The fourth end part 246 is arranged opposite to the third end part 245, and is used to be electrically connected to the connection circuit board 250. The width of the fourth end part 246 is smaller than the width of the third end part 245.

[0121] In addition, the connection part 243 further includes two side surfaces 247, which are respectively located on opposite sides of the third end part 245 and the fourth end part 246, and are arranged opposite to each other. Specifically, each side surface 247 is connected to the same end of the third end part 245 and the fourth end part 246, and is folded relative to the third end part 245 and the fourth end part 246. The two side surfaces 247 are respectively a first side surface 247a and a second side surface 247b. The first side surface 247a is located on the left side of the connection part 243, and is connected to the left end of the third end part 245 and the left end of the fourth end part 246. The second side surface 247b is located on the right side of the connection part 243, and is connected to the right end of the third end part 245 and the right end of the fourth end part 246. For example, the connection part 243 is approximately in the shape of a trapezoid.

[0122] It should be noted that the "left" and "right" and other orientation words used in the description of the display module 200 in the embodiments of the present application are mainly based on the display orientation of the display module 200 in the drawings, and are described as "right" to the positive direction of the Y axis and "left" to the negative direction of the Y axis, which does not limit the orientation of the display module 200 in the actual application scenario.

[0123] Please refer to FIG. 8, which is an assembly structure diagram of the display panel 240, the connection circuit board 250 and the electronic device 280 in the display module 200 shown in FIG. 5.

[0124] The connecting circuit board 250 is arranged on the non-display surface 244 and is electrically connected with the connecting portion 243. The connecting circuit board 250 includes a main body portion 251 and an edge portion 255. The main body portion 251 and the edge portion 255 are both arranged on the non-display surface 244. The main body portion 251 is located at a middle position of the display module 200 and is arranged adjacent to and connected with the connecting portion 243. It should be noted that the main body portion 251 is arranged adjacent to the connecting portion 243 means that the main body portion 251 and the connecting portion 243 are laid on the non-display surface 244, and the main body portion 251 and the connecting portion 243 do not completely overlap on the non-display surface 244.

[0125] Specifically, the main body portion 251 includes a main body part 254, a first end portion 252 and a second end portion (not shown in the figure). The main body part 254 is located on a side of the fourth end portion 246 away from the third end portion 245 and is arranged spaced apart from the connecting portion 243. The first end portion 252 is connected to an edge of the main body part 254 facing the connecting portion 243, overlaps a surface of the fourth end portion 246 away from the non-display surface 244, and is connected with the fourth end portion 246 to form a bonding area 201, so as to realize electrical connection between the first end portion 252 and the fourth end portion 246, and further realize electrical connection between the connecting circuit board 250 and the display panel 240. The second end portion is connected to the main body part 254 and is arranged opposite to the first end portion 252, and is electrically connected with the processor of the electronic device 1000, so as to realize electrical connection between the connecting circuit board 250 and the processor. The connecting circuit board 250 can transmit a display signal sent by the processor to the display panel 240, and the display panel 240 displays a picture according to the display signal.

[0126] The edge portion 255 is located at an edge position of the display module 200 and is located on the same side of the connecting portion 243 and the main body portion 251 and is connected with the main body portion 251. For example, the dashed line of the connecting circuit board 250 in FIG. 8 is a boundary line between the edge portion 255 and the main body portion 251. Specifically, the edge portion 255 extends from an edge of the main body portion 251 to the connecting portion 243 and protrudes toward the edge of the main body portion 251 relative to the connecting portion 243. Wherein, along the width direction (Y-axis direction shown in the figure) of the connecting portion 243 and the main body portion 251, the edge portion 255 is located on one side of the connecting portion 243 and the main body portion 251.

[0127] In this embodiment, the edge portions 255 are two. Along the width direction of the connecting portion 243 and the main body portion 251, the two edge portions 255 are respectively located at opposite sides of the connecting portion 243 and the main body portion 251. Specifically, along the length direction of the first end portion 252 (the Y-axis direction shown in the figure), the two edge portions 255 are respectively connected to opposite sides of the main body portion 254 and the first end portion 252, and both extend from the main body portion 254 toward the direction of the connecting portion 243, and both protrude relative to the first end portion 252 toward the direction of the connecting portion 243. Among them, the two edge portions 255 are respectively located at opposite sides of the connecting portion 243, and are both arranged spaced apart from the connecting portion 243. Each edge portion 255 is arranged spaced apart from and opposite to one side surface 247 of the connecting portion 243, and a gap 202 is formed between each edge portion 255 and the one side surface 247 of the connecting portion 243. Among them, along the length direction of the gap 202, one end of the gap 202 is toward the edge of the display module 200, and the other end is toward the binding area 201.

[0128] In addition, the two edge portions 255 are respectively a first edge portion 255a and a second edge portion 255b. The first edge portion 255a is located at the left side of the first end portion 252, and is arranged spaced apart from and opposite to the first side surface 247a, and a first gap 202a is formed between the first edge portion 255a and the first side surface 247a. The second edge portion 255b is located at the right side of the first end portion 252, and is arranged spaced apart from the first edge portion 255a, and is arranged spaced apart from and opposite to the second side surface 247b, and a second gap 202b is formed between the second edge portion 255b and the second side surface 247b. Among them, along the length direction of the binding area 201 (the Y-axis direction shown in the figure), the first gap 202a and the second gap 202b are respectively located at opposite sides of the binding area 201.

[0129] In this embodiment, the main body portion 254 and the two edge portions 255 can be integrally formed. For example, the connecting circuit board 250 can be a flexible printed circuit (FPC). In other embodiments, the connecting circuit board 250 can also not be a flexible printed circuit, for example, the connecting circuit board 250 can be a soft and hard combined board, at this time, the first end portion 252 and the second end portion can be rigid circuit boards, and the main body portion 254 and the edge portions 255 can be flexible circuit boards.

[0130] In the embodiment, the display module 200 further comprises electronic devices 280, which are arranged on the surface of the connecting circuit board 250 away from the non-display surface 244 and are electrically connected with the connecting circuit board 250 to realize electrical connection with the processor through the connecting circuit board 250. Specifically, the electronic devices 280 are arranged on the side of the edge portion 255 away from the non-display surface 244. Among them, the electronic devices 280 are two, and the two electronic devices 280 are respectively a first electronic device 280a and a second electronic device 280b. The first electronic device 280a is arranged on the side of the first edge portion 255 away from the non-display surface 244, and the second electronic device 280b is arranged on the side of the second edge portion 255 away from the non-display surface 244. Exemplarily, the electronic devices 280 can be display drivers, such as display driver chips (DDIC, display driver IC), or the electronic devices 280 can be touch control drivers, such as touch control chips (TPIC, touch panel IC), or the electronic devices 280 can be flash chips (flash IC).

[0131] It should be noted that in the second main body 110b of the foldable device 100, most of the functional devices such as the battery 112 and the heat dissipation plate 115 are arranged at the middle position of the electronic device 1000 (i.e., the position corresponding to the main body portion 251 of the connecting circuit board 250), and fewer functional devices are arranged at the edge position of the electronic device 1000 (i.e., the position corresponding to the edge portion 255 of the connecting circuit board 250). Therefore, the middle position of the electronic device 1000 is prone to device stacking, resulting in a relatively cramped thickness space at the middle position of the electronic device 1000, while the thickness space at the edge position of the electronic device 1000 is relatively spacious.

[0132] In the display module 200 shown in the embodiment, the electronic devices 280 are arranged at the edge portion 255 of the connecting circuit board 250, which can reduce the thickness space occupied by the position of the main body portion 254 of the display module 200. Not only can a larger thickness space be reserved at the position of the main body portion 254 of the second main body 110b to arrange functional devices, avoiding stacking of the electronic devices 280 and the functional components in the second main body 110 in the thickness direction, but also the position corresponding to the edge portion 255 of the second main body 110b can be used to accommodate the electronic devices 280, thereby increasing the spatial multiplexing of the display module 200 and the second main body 110b in the thickness direction, improving the utilization rate of the internal space of the electronic device 1000, and realizing the thin and light design of the electronic device 1000.

[0133] Referring to FIG. 5, the insulating adhesive layer 260 is arranged on the connecting portion 243 and the side of the connecting circuit board 250 away from the non-display surface 244, and covers at least part of the connecting portion 243, at least part of the connecting circuit board 250, and at least part of the electronic device 280. For example, the insulating adhesive layer 260 covers at least part of the edge portion 255 and all of the electronic device 280. The insulating adhesive layer 260 can protect the connecting portion 243, the connecting circuit board 250, and the electronic device 280, so as to avoid abrasion of the connecting portion 243, the connecting circuit board 250, and the electronic device 280 due to friction with external components, and help improve the use reliability of the display module 200. The insulating adhesive layer 260 can be a cover tape. The insulating adhesive layer 260 can include a plurality of functional layers arranged in sequence. For example, at least one of the functional layers can be an electromagnetic shielding layer, so that the insulating adhesive layer 260 has the function of electromagnetic shielding, and can avoid electromagnetic interference between the connecting portion 243, the connecting circuit board 250, and the electronic device 280 and external components.

[0134] Referring to FIGS. 9 and 10, FIG. 9 is a structural schematic diagram of the insulating adhesive layer 260 in the display module 200 shown in FIG. 5, and FIG. 10 is a partial structural schematic diagram of the display module 200 shown in FIG. 5. In FIG. 10, the sealing adhesive 270 is not shown, and the dotted line with arrows in FIG. 10 exemplarily shows the flow path of the liquid from the gap 202 to the binding area 201.

[0135] Specifically, the insulating adhesive layer 260 covers at least part of the first gap 202a and at least part of the second gap 202b. The insulating adhesive layer 260 includes two side edges 261. The two side edges 261 are arranged opposite to each other along the width direction (the Y-axis direction in the drawing) of the insulating adhesive layer 260. Each side edge 261 spans one gap 202. The two side edges 261 are respectively a first side edge 261a and a second side edge 261b. The first side edge 261a is located on the left side of the insulating adhesive layer 260 and spans the first gap 202a. The second side edge 261b is located on the right side of the insulating adhesive layer 260 and spans the second gap 202b.

[0136] It should be noted that since the connecting portion 243 of the display panel 240, the connecting circuit board 250 and the insulating adhesive layer 260 all have a certain thickness, when the insulating adhesive layer 260 is attached, the insulating adhesive layer 260 is difficult to fill in the gap 202, the insulating adhesive layer 260 cannot completely block the gap 202, and an opening communicated with the gap 202 will be formed between the insulating adhesive layer 260 and the non-display surface 244. In particular, since the electronic device 280 is arranged on the surface of the edge portion 255 away from the non-display surface 244, the electronic device 280 will protrude relative to the edge portion 255, and when the insulating adhesive layer 260 is attached, the electronic device 280 will also affect the adhesion of the insulating adhesive layer 260 to the display panel 240 and the connecting circuit board 250, the edge of the insulating adhesive layer 260 will be raised, and the opening size between the insulating adhesive layer 260 and the non-display surface 244 will be further increased. During use of the electronic device 1000, water or other liquids from the outside will enter the gap 202 from the opening between the insulating adhesive layer 260 and the display portion 242, and then reach the bonding area 201 from the gap 202, thereby corroding the display module 200 and reducing the use reliability of the display module 200, and further reducing the use reliability of the electronic device 1000.

[0137] In the embodiment, the insulating adhesive layer 260 is provided with a through hole 262, the through hole 262 is located between the two side edges 261 and is spaced apart from the two side edges 261, and penetrates the insulating adhesive layer 260 along the thickness direction (the Z-axis direction shown in the figure) of the insulating adhesive layer 260 and exposes the gap 202. The maximum size of the through hole 262 is greater than the width of the gap 202, so that the through hole 262 also exposes the side surface 247 of the connecting portion 243 and the edge portion 255 of the connecting circuit board 250. Exemplarily, the through hole 262 is a square hole.

[0138] Among them, the through hole 262 has two, and the two through holes 262 are respectively a first through hole 262a and a second through hole 262b. The first through hole 262a is located on the left side of the insulating adhesive layer 260 and exposes the first gap 202a, the first side surface 247a and the first edge portion 255a. The second through hole 262b is located on the right side of the insulating adhesive layer 260 and exposes the second gap 202b, the second side surface 247b and the second edge portion 255b. It should be noted that the size, position, shape and number of the through hole 262 can be adaptively adjusted as needed, and the present application does not make specific limitation thereto.

[0139] Referring to FIG. 5, the sealing glue 270 is arranged in the gap 202 and connected with the display part 242, the connecting part 243, the connecting circuit board 250 and the insulating glue layer 260 of the display panel 240 to seal the gap 202. At least part of the sealing glue 270 can be exposed relative to the through hole 262. That is, the through hole 262 can expose at least part of the sealing glue 270. For example, along the thickness direction of the display module 200, the through hole 262 can expose at least part of the sealing glue 270. At this time, the sealing glue 270 can seal the gap 202 and divide the gap 202 into at least two relatively sealed sub-gaps. The sealing glue 270 can prevent external water and other liquids from entering the binding area 201 from the gap 202, improve the waterproof performance of the display module 200, and help improve the use reliability of the display module 200. In addition, the sealing glue 270 can also have an insulating effect to prevent short circuit between the display part 242, the connecting part 243 and the connecting circuit board 250 of the display panel 240, and ensure the use reliability of the display module 200.

[0140] In the embodiment, the sealing glue 270 has two, which are the first sealing glue 270a and the second sealing glue 270b. The first sealing glue 270a is arranged in the first gap 202a and connected between the first side surface 247a of the connecting part 243 and the first bearing part 263 of the connecting circuit board 250 to seal the first gap 202a. The second sealing glue 270b is arranged in the second gap 202 and connected between the second side surface 247b of the connecting part 243 and the second bearing part 264 of the connecting circuit board 250 to seal the second gap 202. At least part of the first sealing glue 270a can be exposed through the first through hole 262a, and at least part of the second sealing glue 270b can be exposed through the second through hole 262b.

[0141] The arrangement of the first sealing glue 270a and the second sealing glue 270b can seal the first gap 202a and the second gap 202b, respectively. When external liquid enters the first gap 202a and the second gap 202b from the opening between the insulating glue layer 260 and the non-display surface 244, the first sealing glue 270a and the second sealing glue 270b can block the liquid to prevent the liquid from entering the binding area 201 from the first gap 202a and the second gap 202b, which can significantly improve the waterproof performance of the display module 200 and ensure the use reliability of the display module 200.

[0142] In the assembly process of the display module 200 shown in the embodiment, the connecting circuit board 250 is first assembled with the display panel 240, then the insulating glue layer 260 is arranged on the non-display surface 244 and covers at least part of the connecting part 243 and at least part of the connecting circuit board 250, the through hole 262 is aligned with the gap 202, and finally the gap 202 is glued through the through hole 262 until the gap 202 is sealed to form the sealing glue 270.

[0143] It can be understood that, in the process of preparing the display module 200 in the preparation factory of the display module 200, the process of forming the blocking glue 270 can be completed together, or in the process of preparing the display module 200 in the preparation factory of the display module 200, the blocking glue 270 can also not be formed first, and then the display module 200 enters the assembly factory of the electronic device 1000, and the blocking glue 270 is formed by dispensing into the gap 202 through the through hole 262 before the display module 200 is assembled with the foldable device 100, and then the display module 200 is assembled with the foldable device 100 to realize the whole machine assembly of the electronic device 1000. In other words, the forming process of the blocking glue 270 can be carried out in the preparation factory of the display module 200 or in the assembly factory of the electronic device 1000, and the forming process of the blocking glue 270 can be flexibly adjusted according to the needs.

[0144] In this embodiment, the maximum size of the through hole 262 is greater than the width of the gap 202, and the through hole 262 not only exposes the gap 202, but also exposes at least part of the connecting portion 243 and at least part of the connecting circuit board 250, such as the side surface 247 of the connecting portion 243 and the edge portion 255 of the connecting circuit board 250, which can ensure that the blocking glue 270 can completely block the gap 202 during dispensing, and ensure the waterproof performance of the display module 200.

[0145] Please refer to FIGS. 11-14, FIG. 11 is a schematic diagram of the back structure of the display module 200 in the electronic device 1000 shown in FIG. 2 under the second embodiment, FIG. 12 is a schematic diagram of the cross-sectional structure of the display module 200 shown in FIG. 11 after being cut along III-III, FIG. 13 is a schematic diagram of the local structure of the display module 200 shown in FIG. 11, and FIG. 14 is a schematic diagram of the structure of the insulating glue layer 260 in the display module 200 shown in FIG. 11. Wherein, FIG. 13 does not show the insulating glue layer 260.

[0146] The display module 200 shown in the embodiment is different from the display module 200 shown in the first embodiment in that the insulating glue layer 260 does not have a through hole and also covers the blocking glue 270. Specifically, the insulating glue layer 260 also covers the first blocking glue 270a and the second blocking glue 270b. Under this setting, the first blocking glue 270a and the second blocking glue 270b can still block the liquid flowing from the gap 202 to the binding area 201, which can significantly improve the waterproof performance of the display module 200 and ensure the use reliability of the display module 200. It should be noted that the length of the blocking glue 270 can be adjusted adaptively according to the needs, which is not limited in the present application.

[0147] In the assembling process of the display module 200 shown in the embodiment, the connecting circuit board 250 is assembled with the display panel 240 first, then the gap 202 is glued until the gap 202 is blocked to form the blocking glue 270, and finally the insulating glue layer 260 is arranged on the non-display panel 244 to cover at least part of the connecting portion 243, at least part of the connecting circuit board 250 and the blocking glue 270.

[0148] It can be understood that, in the assembling process of the display module 200 shown in the embodiment, the blocking glue 270 is formed by gluing first, and then the insulating glue layer 260 is attached, without the need to glue the gap 202 through the through hole of the insulating glue layer 260. This not only simplifies the forming process of the blocking glue 270, but also reserves a larger operation work to form the blocking glue 270, which can ensure that the blocking glue 270 can completely block the gap 202. Moreover, the insulating glue layer 260 does not need to be perforated, which can simplify the preparation process of the display module 200 and help to reduce the cost of the display module 200. Furthermore, under this setting, the blocking glue 270 will not be exposed relative to the insulating glue layer 260, which helps to ensure the flatness of the back of the display module 200, avoids the problem of interference between the display module 200 and the foldable device 100 in the subsequent process, and helps to improve the assembly efficiency between the display module 200 and the foldable device 100.

[0149] Please refer to FIG. 15, which is a schematic diagram of the back structure of the display module 200 in the third embodiment of the electronic device 1000 shown in FIG. 2.

The multiple first through holes 262a are arranged at intervals and can be arranged in sequence along the length direction of the first gap 202a. The multiple second through holes 262b are arranged at intervals and can be arranged in sequence along the length direction of the second gap 202b. Among them, at least one first through hole 262a exposes at least part of the first blocking glue 270a. At least one second through hole 262b exposes at least part of the second blocking glue 270b.

[0151] Exemplarily, the plurality of through holes 262 and the plurality of sealing rubbers 270 are both six, and each through hole 262 exposes at least part of one sealing rubber 270. The six through holes 262 include three first through holes 262a and three second through holes 262b.

It should be noted that the number of the first through holes 262a and the first sealing rubbers 270a can be different from the number of the second through holes 262b and the second sealing rubbers 270b, which is not limited in the present application.

[0153] Please refer to FIG. 16, which is a schematic diagram of the back structure of the display module 200 in the fourth embodiment of the electronic device 1000 shown in FIG. 2.

[0154] The display module 200 shown in the present embodiment is different from the display module 200 shown in the first embodiment in that the through holes 262 and the sealing rubbers 270 are both four.

Each second through hole 262b exposes at least part of one second sealing rubber 270b.

[0155] Compared with the display module 200 shown in the first embodiment, the display module 200 shown in the present embodiment adopts two first sealing rubbers 270a and two second sealing rubbers 270b, which can improve the sealing effect of the first gap 202a and the second gap 202b, help to improve the waterproof performance of the display module 200, and ensure the use reliability of the display module 200.

[0156] It should be noted that in other embodiments, the number of the first through holes 262a and the first sealing glue 270a can also be more than four, or the number of the second through holes 262b and the second sealing glue 270b can also be more than four, and the number of the through holes 262 and the sealing glue 270 is not limited in the present application.

[0157] Please refer to FIG. 17, which is a schematic diagram of the back structure of the display module 200 in the fifth embodiment of the electronic device 1000 shown in FIG. 2.

[0158] The display module 200 shown in the present embodiment is different from the display module 200 shown in the first embodiment in that the through holes 262 are circular holes, and both the through holes 262 and the sealing glue 270 are six. The six through holes 262 include three first through holes 262a and three second through holes 262b. Along the length direction of the first gap 202a, the three first through holes 262a are arranged in sequence with intervals. Along the length direction of the second gap 202b, the three second through holes 262b are arranged in sequence with intervals. The six sealing glues 270 include three first sealing glues 270a and three second sealing glues 270b. Each first through hole 262a exposes at least part of one first sealing glue 270a. Each second through hole 262b exposes at least part of one second sealing glue 270b.

[0159] Compared with the display module 200 shown in the first embodiment, the display module 200 shown in the present embodiment uses three first sealing glues 270a and three second sealing glues 270b, which can improve the sealing effect of the first gap 202a and the second gap 202b, help to improve the waterproof performance of the display module 200, and ensure the use reliability of the display module 200.

[0160] Please refer to FIG. 18 and FIG. 19, which are a schematic diagram of the back structure of the display module 200 in the sixth embodiment of the electronic device 1000 shown in FIG. 2, and FIG. 19 is a schematic diagram of the partial structure of the display module 200 shown in FIG. 18. Among them, the insulating glue layer 260 is not shown in FIG. 18.

[0161] The display module 200 shown in the present embodiment is different from the display module 200 shown in the second embodiment in that the sealing glue 270 includes two sub-sealing glues 271. Along the length direction of the gap 202, the two sub-sealing glues 271 are arranged with intervals.

Along the length direction of the second gap 202b, the two sub-sealing glues 271 of the second sealing glue 270b are arranged with intervals.

[0162] Compared with the display module 200 shown in the second embodiment, the display module 200 shown in the present embodiment is provided with the first sealing glue 270a and the second sealing glue 270b in segments, which not only ensures the waterproof performance of the display module 200, but also saves the dispensing cost of the display module 200. It should be noted that in other embodiments, the sealing glue 270 can also include more than three sub-sealing glues 271, which is not limited in the present application.

[0163] Please refer to FIG. 20, which is a cross-sectional structure diagram of the electronic device 1000 along IV-IV shown in FIG. 2.

[0164] The display module 200 is arranged on the top surface of the shell 111. Specifically, the display module 200 is arranged on the top surface of the middle frame 116. That is, the display module 200 and the back cover 117 are arranged on opposite sides of the middle frame 116. Among them, the display part 242 of the display panel 240 is arranged on the top surface of the middle frame 116. In addition, the electronic device 1000 also includes an adhesive layer 300, which is located between the display part 242 and the middle frame 116 and is adhered between the display part 242 and the middle frame 116 to realize the assembly between the display module 200 and the shell 111.

[0165] In the present embodiment, the connection part 243 of the display panel 240, the connection circuit board 250, the insulating glue layer 260, the sealing glue 270 and the electronic device 280 are all arranged on the side of the display part 242 facing the middle frame 116. Specifically, along the thickness direction of the electronic device 1000, the battery 112, the heat dissipation plate 115 and the main body part 251 of the connection circuit board 250 are stacked. The electronic device 280 and at least part of the insulating glue layer 260 can extend into the avoiding groove 1162 of the middle frame 116. In other words, the avoiding groove 1162 can avoid the electronic device 280 and at least part of the insulating glue layer 260. Among them, the first electronic device 280a and at least part of the insulating glue layer 260 can extend into the first avoiding groove 1162a. The second electronic device 280b and at least part of the insulating glue layer 260 can extend into the second avoiding groove 1162b. Along the thickness direction of the electronic device 1000, the circuit board 113, the electronic device 280 and the edge part 255 of the connection circuit board 250 are stacked, and the functional module 114 is arranged in a staggered manner with the electronic device 280. It should be noted that the staggered arrangement of the functional module 114 and the electronic device 280 means that the projection of the electronic device 280 on the circuit board 113 is completely staggered with the functional module 114, and the two do not overlap.

[0166] It should be noted that, in the thickness direction of the electronic device 1000, the stacking of the battery 112, the heat dissipation plate 115 and the main body part 251 of the connecting circuit board 250 means that the projections of the battery 112 and the heat dissipation plate 115 on the connecting circuit board 250 at least partially coincide with the main body part 251 in the thickness direction of the electronic device 1000, and similar descriptions herein can be understood in the same way.

[0167] In this arrangement, in the thickness direction of the electronic device 1000, the electronic device 280 is not stacked with the battery 112 and the heat dissipation plate 115, but is stacked with the part of the circuit board 113 on which the functional module 114 is not arranged. The electronic device 280 and the at least partially insulating adhesive layer 260 can reuse the space of the middle frame 116 in the thickness direction to reduce the space occupation of the display module 200 in the thickness direction of the electronic device 1000, improve the space utilization inside the electronic device 1000, and help to realize the thin design of the electronic device 1000. In other embodiments, the electronic device 280 can also not extend into the avoiding slot 1162, and only the insulating adhesive layer 260 covers the electronic device 280, which is not limited in the present application.

[0168] It should be noted that, in the present embodiment, the assembly methods of the display module 200 and the first main body 110a in different embodiments are substantially the same. FIG. 20 exemplarily shows an assembly view of the display module 200 and the first main body 110a in the first embodiment, and the assembly methods of the display module 200 and the first main body 110a in other embodiments can refer to the assembly method of FIG. 20, which will not be described herein.

[0169] Please refer to FIG. 21 and FIG. 22, FIG. 21 is a partial structure schematic view of the second main body 110b of the foldable device in the second electronic device provided by the present application, and FIG. 22 is a cross-sectional structure schematic view of the second main body 110b shown in FIG. 21 along V-V.

[0170] The difference between the second main body 110b in the electronic device shown in the present embodiment and the second main body 110b in the first electronic device 1000 described above is that the sealing adhesive 270 is arranged on the surface of the middle frame 116 of the shell 111 away from the back cover 117, and is arranged in a spaced manner with the avoiding slot 1162. Specifically, the sealing adhesive 270 protrudes away from the back cover 117 from the surface of the middle frame 116 away from the back cover 117 (the positive direction of the Z axis shown in the figure). Among them, the sealing adhesive 270 has two, and the two sealing adhesives 270 are respectively the first sealing adhesive 270a and the second sealing adhesive 270b. The first sealing adhesive 270a is located on the side of the first avoiding slot 1162a facing the second avoiding slot 1162b. The second sealing adhesive 270b is located on the side of the second avoiding slot 1162b facing the first avoiding slot 1162a.

[0171] Please refer to FIG. 23 to FIG. 25, FIG. 23 is a schematic diagram of the back structure of the display module 200 in the second electronic device provided by the present application, FIG. 24 is a schematic diagram of the cross-sectional structure of the display module 200 shown in FIG. 23 along VI-VI, and FIG. 25 is a schematic diagram of the cross-sectional structure of the second electronic device 1000 provided by the present application.

[0172] In the process of mounting the display module 200 on the foldable device 100, the sealing glue 270 passes through the through hole 262 of the insulating glue layer 260 and is arranged in the gap 202 and connected with the display part 242, the connecting part 243, the connecting circuit board 250 and the insulating glue layer 260 of the display panel 240, so as to seal the gap 202. Specifically, the first sealing glue 270a passes through the first through hole 262a and is arranged in the first gap 202a and connected between the first side surface 247a of the connecting part 243 and the first bearing part 263 of the connecting circuit board 250, so as to seal the first gap 202a. The second sealing glue 270b passes through the second through hole 262b and is arranged in the second gap 202b and connected between the second side surface 247b of the connecting part 243 and the second bearing part 264 of the connecting circuit board 250, so as to seal the second gap 202b.

[0173] In the electronic device 1000 shown in the present embodiment, the first sealing glue 270a and the second sealing glue 270b are arranged on the shell 111 of the second main body 110b to seal the first gap 202a and the second gap 202b respectively. When the liquid from the outside enters the first gap 202a and the second gap 202b from the opening between the insulating glue layer 260 and the non-display surface 244, the first sealing glue 270a and the second sealing glue 270b can block the liquid, so as to prevent the liquid from entering the binding area 201 from the first gap 202a and the second gap 202b, which can significantly improve the waterproof performance of the display module 200, ensure the use reliability of the display module 200, and further improve the use reliability of the electronic device 1000.

[0174] It can be understood that, before the display module 200 and the foldable device 100 are assembled in the assembly factory of the electronic device 1000, the sealing glue 270 is formed on the shell 111, and then in the assembly process of the display module 200 and the foldable device 100, the sealing glue 270 passes through the through hole 262 and is arranged in the gap 202. Therefore, in the preparation factory of the display module 200, the forming process of the sealing glue 270 is not needed, and the related structure for forming the sealing glue 270 does not need to be configured on the assembly equipment of the display module 200, which can effectively save the preparation cost of the display module 200.

[0175] In the electronic device 1000 shown in the present application, the display module 200 is arranged with the electronic device 280 at the edge portion 255, which can reduce the thickness of the display module 200 at the position of the main body portion 251 of the connecting circuit board 250, not only can reduce the thickness space occupied by the display module 200 at the middle position of the electronic device 1000, but also can reserve larger thickness space for the functional components (such as the battery 112 and the heat dissipation plate 115) located at the middle position of the electronic device 1000, avoid the stacking of the electronic device 280 and these functional components in the thickness direction, and further set the avoiding groove 1162 on the shell 111 to avoid the electronic device 280, so as to increase the space multiplexing of the display module 200 and the shell 111 in the thickness direction, improve the space utilization of the electronic device 1000 in the thickness direction, and realize the light and thin design of the electronic device 1000.

[0176] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, 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 in 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.
