Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a display screen and an electronic device. Background Art

[0002] At present, mobile phones, computers and other electronic devices have become inseparable from our lives, can be seen everywhere in life, and have greatly improved people's living standards. With the rapid development of communication equipment technology, the display-related industry has also continued to develop, and the application range of display screens has become more and more extensive.

[0003] The display screen may include a backlight module and a display module. The display module is located on one side of the backlight module. The backlight module may provide light for the display module. The display module may modulate the light provided by the backlight module into a visible image to realize display. The backlight module may include a supporting iron frame. The supporting iron frame may include a bottom plate and side plates arranged around the bottom plate. The bottom plate and the side plates form a receiving cavity for receiving the film layers of the backlight module. Part of the side plate usually surrounds the periphery of the display module. The display screen also includes a Mylar rubber part. The cross section of the Mylar rubber part is in the shape of a "匚" character. One end of the Mylar rubber part is pasted on the side of the display module facing away from the bottom plate. The middle part of the Mylar rubber part is pasted on the side plate of the iron frame. The other end of the Mylar rubber part is pasted on the bottom plate of the iron frame, so that the Mylar rubber part covers the edge of the side plate and the display module. The Mylar rubber part can prevent light leakage and strengthen the assembly strength between the display module and the backlight module. The supporting iron frame and the Mylar rubber parts are light-proof structures, so that the display screen includes a display area and a black border area (non-display area).

[0004] However, the black border area of ​​the above display screen is wide, which reduces the screen-to-body ratio of the display screen and affects the visual experience. Summary of the invention

[0005] The present application provides a display screen and an electronic device, which significantly reduces the width of the black border area of ​​the display screen, realizes a narrowing design of the black border area of ​​the display screen, and improves the visual experience.

[0006] In a first aspect, an embodiment of the present application provides a display screen, comprising a display module, a backlight module and a first adhesive layer, wherein the display module comprises a first side surface, a first surface and a second surface, the first surface and the second surface are opposite to each other, the first side surface is located between the first surface and the second surface, and the first side surface is arranged around the first surface and the second surface.

[0007] The backlight module is stacked below the second surface of the display module. The backlight module includes a support member with an accommodation cavity formed inside. The support member is fixed to the second surface and includes a second side surface that surrounds the accommodation cavity. In this way, the backlight module is stacked below the second surface of the display module, and the display module is fixed to the support member located below the display module. Compared with the display screen in the related art, the support member of the backlight module is not arranged around the periphery of the display module, and there may be no gap between the support member and the peripheral side surface (i.e., the first side surface) of the display module. The second side surface of the support member can be arranged approximately flush with the first side surface of the display module, and the display screen does not need to be provided with a mylar glue member to cover the side plate, the edge of the display module, and the gap between the side plate and the display module.

[0008] The black edge area of the display screen can be the area between the second side surface (or the first side surface) of the support member and the display area (such as the AA area) of the display screen. The width of the black edge area is the distance between the second side surface (or the first side surface) of the support member and the display area. Compared with the width of the black edge area of the display screen in the related art, at least the thickness of the mylar glue member, the thickness of the side plate, and the gap between the side plate and the peripheral side surface of the display module are reduced, significantly reducing the width of the black edge area of the display screen, achieving the narrowing of the black edge area of the display screen, improving the screen occupation ratio of the display screen, meeting the user's demand for large-screen display, and enhancing the visual experience.

[0009] The first adhesive layer covers the first side surface and the second side surface, and the display module is also fixed to the support member through the first adhesive layer. The first adhesive layer plays an auxiliary connection role and strengthens the fixed assembly strength of the display module and the backlight module. The first adhesive layer is a light-shielding layer, and the first adhesive layer can be an opaque glue layer, which plays a light-shielding role to prevent light from leaking out from the first side surface of the display module and improve the display effect.

[0010] Moreover, the first adhesive layer covers the first side surface and the second side surface and does not cover the display surface (i.e., the first surface) of the display module. The visual consistency and delicacy on the display surface side of the display screen are relatively high. When assembling into an electronic device, there is no need to set up a light-shielding structure to block the mylar glue member, improving the visual consistency and delicacy of the whole electronic device, and also being able to reduce the occupied space of the light-shielding structure in the thickness direction, which is beneficial to the thinning of the electronic device. And it also reduces the number of components of the electronic device, which is beneficial to cost reduction and weight reduction.

[0011] In a possible implementation manner, the distance range between the first side surface and the second side surface includes 0 mm to 0.05 mm. Within a certain assembly and production processing tolerance range, it is ensured that the peripheral side surfaces of the display panel and the polarizer can reach an approximately flush effect after assembly, which is convenient for processing and assembly.

[0012] In a possible implementation, the first side face is flush with the second side face, that is, the peripheral side face of the display panel and the peripheral side face of the polarizer can be located on the same plane, and the formed first side face can be a smooth plane, and the distance between the peripheral side face of the display panel and the peripheral side face of the polarizer can be 0 mm. This makes the display screen have higher visual consistency and refinement, and is more conducive to improving the appearance of the display screen and the entire electronic device.

[0013] In a possible implementation, the first adhesive layer completely covers the first side face, which can effectively prevent light from leaking out of the first side face of the display module, achieving a good light leakage prevention effect and being beneficial to improving the display effect of the display screen.

[0014] The first adhesive layer covers at least a part of the second side face. For example, the first adhesive layer can only cover a part of the second side face. Under the condition of ensuring high assembly firmness between the display module and the support member, the size of the first adhesive layer can be reduced, which is beneficial to cost reduction and weight reduction.

[0015] In a possible implementation, the support member includes a bottom wall and a side wall. The side wall is surrounded on the surface of the bottom wall facing the display module, and the bottom wall and the side wall enclose a receiving cavity. The side of the side wall facing away from the receiving cavity forms the second side face.

[0016] The display screen further includes a second adhesive layer. The second adhesive layer is located between the end face of the side wall away from the bottom wall and the second surface of the display module. The side wall is fixed to the display module through the second adhesive layer, thereby realizing the stable assembly of the display module and the backlight module. The structural design of the support member is simple, and the assembly method between the support member and the display module is simple, which is convenient for processing and assembly.

[0017] In a possible implementation, the side wall includes a first wall body and an extension structure. The first end of the first wall body is fixed to the bottom wall, and the extension structure is arranged on the second end of the first wall body, and the extension structure protrudes from the surface of the first wall body facing the receiving cavity. For example, one end of the extension structure can be fixed to the second end of the first wall body, and the other end of the extension structure can extend a certain length away from the second end of the first wall body.

[0018] The second adhesive layer is located between the extension structure and the display module, so that the support member is adhesively fixed to the second surface of the display module through the extension structure. The extension length of the extension structure is relatively large, so that the second adhesive layer can have a relatively large occupied area, which is beneficial to increasing the adhesive area between the support member and the display module and improving the assembly firmness and support strength between the support member and the display module.

[0019] In addition, compared with the display screens in related technologies, by using the extended structure of the support member to bond and fix with the display module, there is no need to set plastic parts in the accommodation cavity of the support member, which can reduce the occupied space of the plastic parts, facilitate narrowing the distance between the side wall of the support member and the peripheral side surface of the backlight assembly, and can further reduce the width of the black border area.

[0020] In a possible implementation manner, the first wall body and the extended structure are an integral structural member, that is, the first wall body and the extended structure can be formed into an integral structural member by an integral molding method, and the side wall can be an integral structural member. This is beneficial to enhancing the mechanical properties and strength of the extended structure, improving the assembly stability between the support member and the display module, and is also beneficial to increasing the support strength of the support member for the display module, thereby enhancing the stability and reliability of the display screen.

[0021] In a possible implementation manner, the side wall further includes a first structural member, the first structural member is arranged between the extended structure and the bottom wall, and the opposite end faces of the first structural member are respectively abutted against the extended structure and the bottom wall. The first structural member can fill the gap between the extended structure and the bottom wall, play a supporting role for the extended structure, further strengthen the mechanical properties and strength of the extended structure, and further improve the assembly stability between the support member and the display module and the support strength of the support member for the display module.

[0022] In a possible implementation manner, the side wall includes a first wall body and a second structural member, the first end of the first wall body is fixed to the bottom wall. The second structural member is located inside the first wall body and fits against the inner side surface of the first wall body.

[0023] Part of the second adhesive layer is located between the second structural member and the display module, and part of the second adhesive layer is located between the second end of the first wall body and the display module.

[0024] The setting of the second structural member can increase the extension length of the entire side wall (such as the extension length in the y direction), so that the second adhesive layer can have a larger occupied area, increase the bonding area between the support member and the display module, and is beneficial to improving the assembly firmness and support strength between the support member and the display module. In addition, the second structural member is arranged to fit against the inner side surface of the first wall body. Under the condition of increasing the bonding area, it is beneficial to narrow the distance between the second structural member and the first wall body, so as to further reduce the distance between the second structural member (or the entire side wall) and the peripheral side surface of the backlight assembly, and further reduce the width of the black border area.

[0025] In a possible implementation manner, the side wall includes a first wall body and a second structural member, the first end of the first wall body is fixed to the bottom wall.

[0026] The second structural member includes a first split portion and a second split portion. The second split portion is located inside the first wall body and fits against the inner side surface of the first wall body. A part of the first split portion covers one end of the first split portion away from the bottom wall, and a part of the first split portion covers the second end of the first wall body, so that the outer contour shape of the cross-section of the entire second structural member can be in an L-like shape.

[0027] The second adhesive layer is located between the first split portion and the display module. The first split portion has a relatively wide extension length, which can provide a relatively large layout area for the second adhesive layer, can increase the bonding area between the support member and the display module, and improve the assembly firmness and support strength between the support member and the display module. In addition, the second split portion is arranged to fit against the inner side surface of the first wall body. Under the condition of increasing the bonding area, the distance between the second split portion and the first wall body is shortened, which is beneficial to further reducing the distance between the second structural member (or the entire side wall) and the peripheral side surface of the backlight assembly, and reducing the width of the black edge area.

[0028] In a possible implementation, the display module includes a polarizer and a display panel, and the polarizer is located on the side of the display panel facing away from the display module.

[0029] The peripheral side surface of the polarizer and the peripheral side surface of the display panel together form a first side surface, and the first side surface is a smooth surface. That is, the peripheral side surface of the display panel and the peripheral side surface of the polarizer can be located on the same plane, and the formed first side surface can be a smooth plane, and the distance between the peripheral side surface of the display panel and the peripheral side surface of the polarizer can be 0 mm. This makes the display screen have higher visual consistency and delicacy, and is more conducive to improving the appearance of the display screen and the entire electronic device.

[0030] In a possible implementation, the display screen further includes a protective layer, and the protective layer is located above the first surface of the display module. The protective layer is fixed to the display module through the first adhesive layer, and the first adhesive layer is used to fix the protective layer to the display module and the backlight module, so that the entire display screen can be assembled into an integral structural member, which is convenient for the assembly of the display screen and the housing (such as the second housing). And there is no need to additionally set an adhesive layer or the like to connect the protective layer and the display module, which is beneficial to reducing the number of components of the display screen, reducing costs and weight.

[0031] In a possible implementation, the protective layer protrudes from the first side of the display module, and the first adhesive layer partially covers the surface of the protective layer facing the display module, so that the first adhesive layer can connect and assemble the protective layer, the display module and the support member together. For example, in the thickness direction, the first adhesive layer is located below the surface of the protective layer facing the display module. Compared with the case where the first adhesive layer is located above the peripheral side surface of the protective layer or the surface of the protective layer facing away from the display module, the protective layer can play a certain shielding effect on the first adhesive layer. This is beneficial to further improving the consistency and delicacy of the display screen on the display surface side and enhancing the appearance of the display screen.

[0032] In addition, the protective layer protruding from the display module can also play a better protective role for the display module, the first adhesive layer, etc., reducing or avoiding damages such as the peeling off and cracking of the first adhesive layer, ensuring the assembly firmness and stability of the display module, the protective layer and the backlight module, and being beneficial to realizing the high stability and reliability of the display screen.

[0033] In a possible implementation, the display screen further includes a shielding layer. The shielding layer is located on the side of the protective layer facing the display module. Part of the shielding layer covers the edge of the first surface, and part of the shielding layer covers the first adhesive layer. The shielding layer can play a shielding role for the first adhesive layer and the edge where the first adhesive layer is connected to the first side, which is beneficial to improving the appearance effect of the display screen.

[0034] In a possible implementation, the height range of the protective layer protruding from the first side includes 0.3 mm to 0.45 mm, which ensures that the protective layer can play a good protective effect on the first adhesive layer, the display module, etc., and is beneficial to realizing the design of narrowing the black edge area of the display screen.

[0035] In a possible implementation, the distance range from the second side to the display area of the display screen includes 1.7 mm to 1.9 mm. The width of the black edge area of the display screen is relatively small. Compared with the display screen of the related technology, the width of the black edge area is reduced by about 0.6 mm, which well realizes the design of narrowing the black edge of the display screen, enables the display screen to have a larger screen occupation ratio, and significantly improves the visual experience.

[0036] In a second aspect, an embodiment of the present application further provides an electronic device, including a housing and the display screen of any one of the above, and the display screen is arranged on the housing.

[0037] It should be understood that the second aspect of the present application corresponds to the technical solution of the first aspect of the present application, and the beneficial effects obtained by each aspect and the corresponding feasible implementation manners are similar, and will not be repeated here.

[0061] The terms used in the implementation part of this application are only for explaining the specific embodiments of this application, rather than aiming to limit this application.

[0062] The embodiments of this application provide an electronic device, which may include but is not limited to electronic devices with a display screen such as laptops, tablets (i.e., pads), mobile phones, drones, virtual reality (VR) devices, augmented reality (AR) devices, personal computers (PCs), ultra-mobile personal computers (UMPCs), handheld computers, netbooks, smart wearable devices, point of sales (POS), personal digital assistants (PDAs), in - vehicle devices, etc.

[0063] The electronic device can be a non - foldable electronic device. For example, the electronic device can be a straight - bar mobile phone, a tablet computer, etc., and the electronic device cannot be relatively folded or unfolded.

[0064] Alternatively, the electronic device can also be a foldable electronic device. For example, the electronic device can be a foldable mobile phone, a laptop computer, etc. Under different usage requirements, the electronic device can be unfolded to the open state or folded to the closed state.

[0065] In the embodiments of this application, taking the electronic device as a foldable electronic device, such as a laptop computer as an example for illustration.

[0066] Figure 1 It is a schematic structural diagram of an electronic device provided by the embodiments of this application in the open state.

[0067] Exemplarily, refer to Figure 1 As shown, the electronic device 100 may include a display 1, a keyboard host 2, and a hinge mechanism 3. Among them, the display 1 is used to display images, videos, etc. The keyboard host 2 is used to input instructions and data, and control the display 1 to display images, videos, etc. according to the input instructions and data.

[0068] The rotating shaft mechanism 3 can be located at the connection between the display 1 and the keyboard main unit 2, enabling the display 1 and the keyboard main unit 2 to be rotatably connected through the rotating shaft mechanism 3. The display 1 can rotate relative to the keyboard main unit 2 to realize the switching of the electronic device 100 between different states.

[0069] As shown in Figure 1 When the electronic device 100 is in the open state, an included angle greater than 0° and less than 360° can be formed between the keyboard main unit 2 and the display 1. In this state, the user can operate the keyboard main unit 2 to control the display of the display 1, and the user can also view the images or videos displayed on the display 1.

[0070] When the electronic device 100 is in the closed state, the display 1 can cover the keyboard main unit 2, and the display surface of the display 1 can face the keyboard surface of the keyboard main unit 2. In this state, the user cannot operate the keyboard main unit 2, nor can they view images or videos through the display 1.

[0071] For the convenience of describing the embodiments below, an xyz coordinate system is established. For example, the axis direction of the relative rotation between the keyboard main unit 2 and the display 1 is the y direction, and the y direction can also be used as the length direction of the display 1. The thickness direction of the display 1 and the keyboard main unit 2 is the z direction, and the width direction of the display 1 is the x direction. The length direction, width direction, and thickness direction can be perpendicular to each other.

[0072] It can be understood that the coordinate system setting can be flexibly set according to actual needs and is not specifically limited here. The length, width, and thickness in the embodiments of the present application are only for the convenience of description and do not imply any limitation on the size. For example, the length can be greater than, equal to, or less than the width.

[0073] In some examples, the keyboard main unit 2 can include a keyboard 21 and a housing (such as the first housing 22). The keyboard 21 is used to input instructions or data. The keyboard 21 can be arranged on one surface of the first housing 22, and the surface of the first housing 22 with the keyboard 21 can be the keyboard surface of the keyboard main unit 2.

[0074] The first housing 22 can have an installation cavity (not shown in the figure) inside. The electronic device 100 can also include components such as a main control board, a battery, and a radiator (not shown in the figure), and such components can be arranged in the installation cavity of the first housing 22.

[0075] In some examples, the material of the first housing 22 can include but is not limited to metals, aluminum alloys, magnesium alloys, stainless steels, plastics, etc.

[0076] The keyboard host 2 may further include a touchpad 23, and the touchpad 23 and the keyboard 21 may be located on the same surface of the first housing 22. The touchpad 23 can recognize the touch operations of the user, and the user can input instructions and data through the touchpad 23.

[0077] In some examples, the display 1 may include a display screen 11 (panel) and a housing (such as the second housing 12). The display screen 11 may include an opposite display surface and a non-display surface. The display surface is used to implement the display of images, videos, etc. The display surface of the display screen 11 may be the display surface of the display 1.

[0078] The display screen 11 may be disposed on the second housing 12. The second housing 12 can support the display screen 11 and provide protection for the display screen 11. For example, an assembly cavity (not shown in the figure) may be provided inside the second housing 12, and the display screen 11 may be assembled in the assembly cavity. The second housing 12 can cover the edge of the display screen 11 for one week and the non-display surface of the display screen 11.

[0079] Exemplarily, the display screen 11 may be a liquid crystal display (LCD). For example, the display screen 11 may be a thin-film transistor (TFT) liquid crystal display, an in-plane switching (IPS) liquid crystal display, etc.

[0080] Among them, the display screen 11 may include a display area. For example, the display area may include an active area (AA area), which may be the area on the display screen actually used for displaying images. The display area may further include a view area (VA area), which may be the actually visible display area that the user can see during use. The VA area may cover the AA area, and the size of the VA area (such as the dimensions along the x direction and the y direction) may be slightly larger than the AA area. For example, the difference may be about 0.3 mm, which can accommodate the manufacturing tolerances of the AA area and leave a certain space around the AA area. This space may not display useful information such as images or videos and can be illuminated by the backlight module to ensure the uniformity of the display effect of the display screen.

[0081] The display screen 11 may further include a non-display area, which is the area on the display screen 11 not used for displaying images, videos, etc. The non-display area may surround the display area.

[0082] In some examples, the material of the second housing 12 may include but is not limited to metals, aluminum alloys, magnesium alloys, stainless steels, plastics, etc.

[0083] In some examples, a touch film layer may be integrated in the display screen 11, so that the display screen 11 may have a touch function, and the display 1 may be a touch display. Of course, in some other examples, the display screen 11 may not have a touch film layer integrated therein, and the display screen 11 may not have a touch function.

[0084] Figure 2 It is a cross-sectional schematic diagram of an electronic device in the related art.

[0085] in, Figure 2 FIG. 2 shows a cross-sectional schematic diagram of an LCD display screen 200 and a second housing 202 being assembled. Figure 2 As shown in , the display screen 200 may generally include a backlight module 212 and a display module 211. The backlight module 212 may provide light for the display module 211, and the display module 211 may modulate the light into an image to realize display. The display module 211 may include an upper surface and a lower surface opposite to each other, and the upper surface of the display module 211 may serve as the display surface of the display screen 200.

[0086] The backlight module 212 may include a support frame 2122 and a backlight assembly 2121. The support frame 2122 may be surrounded by a receiving cavity. For example, the support frame 2122 may include a bottom plate 2122a and a side plate 2122b. The side plate 2122b may be arranged on one side of the bottom plate 2122a. The side plate 2122b and the bottom plate 2122a form a receiving space.

[0087] The backlight assembly 2121 may be disposed in the accommodation space of the support frame 2122, and the backlight assembly 2121 may be located below the lower surface of the display module 211 (e.g., on the side away from the upper surface in the thickness direction (e.g., z direction)), that is, the bottom plate 2122a, the backlight assembly 2121, and the display module 211 may be stacked in sequence in the thickness direction (e.g., z direction), and the bottom plate 2122a may provide support for the backlight assembly 2121, the display module 211, etc. The backlight assembly 2121 may serve as a light source to provide light for the display module 211 above.

[0088] Part of the side panel 2122b will surround the periphery of the display module 211 to protect and shield the peripheral side of the display module 211. Considering the assembly tolerance and avoiding the display module 211, a gap is usually maintained between the side panel 2122b and the peripheral side of the display module 211. A plastic part 213 is also arranged in the accommodation space of the support frame 2122. The plastic part 213 can be arranged around the backlight assembly 2121. The plastic part 213 can be located below the lower surface of the display module 211. One end of the plastic part 213 is fixed to the support frame 2122, and the other end of the plastic part 213 can be fixed to the lower surface of the display module 211 through an adhesive layer, so as to realize the fixed assembly of the display module 211 and the backlight module 212.

[0089] The display screen 200 also includes a Mylar glue component 214, which may be a structural component made of Mylar (or polyester film, mylar) glue. The Mylar glue component 214 may extend from the upper surface side of the display module 211 to the side of the bottom plate 2122a facing away from the display module 211, so that one end of the Mylar glue component 214 is adhered to the edge of the upper surface of the display module 211, the middle part of the Mylar glue component 214 is adhered to the outer surface of the side panel 2122b (the side facing away from the accommodating space), and the other end of the Mylar glue component 214 is adhered to the side of the bottom plate 2122a facing away from the display module 211. The cross-sectional profile of the Mylar rubber piece 214 is in a shape similar to the Chinese character "匚". The Mylar rubber piece 214 covers the side plate 2122b, the edge of the display module 211, and the gap between the side plate 2122b and the outer side of the display module 211 to prevent light from leaking from the outer side and gap of the display module 211 and affecting the display effect. The Mylar rubber piece 214 can also strengthen the fixing strength between the display module 211 and the support frame 2122 of the backlight module 212.

[0090] The support frame 2122, the plastic part 213, and the Mylar rubber part 214 are all light-proof structures, so that the display screen 200 has a black border area 215 (border). The black border area 215 can be set around the display area (such as the AA area) of the display screen 200, and the black border area 215 is a non-display area. The black border area 215 can be the area between the Mylar rubber part 214 on the side plate 2122b and the display area (such as the AA area). The width of the black border area 215 can be the distance (such as the distance along the y direction in the figure) from the outer surface of the Mylar rubber part 214 on the side plate 2122b (the side facing away from the side plate 2122b) to the display area (such as the AA area), as shown by D1 in the figure.

[0091] See also Figure 2 As shown, when the display screen 200 is assembled on the second shell 202 to assemble into an electronic device, a black shading structure 204 is also set above the display surface of the display screen 200. The vertical projection of the black shading structure 204 on the display screen 200 can cover the Mylar rubber part 214 to play a shielding role to enhance the aesthetics.

[0092] However, the black border area of ​​the display screen of the above-mentioned structure is wide, which will reduce the screen-to-body ratio of the display screen, making it difficult to meet the user's pursuit of large-screen display and affecting the visual experience. In addition, the Mylar rubber part partially covers the upper surface of the display module, making the visual consistency of the display surface side of the display screen poor. When assembled into an electronic device, a shading structure is required to block it. The shading structure is located above the display surface of the display screen and has a height difference in the thickness direction (such as the z direction), which will cause the visual consistency and refinement of the entire device on the display surface side to be poor, affecting the aesthetics of the electronic device.

[0093] Based on this, an embodiment of the present application provides a display screen, which includes a display module, a backlight module, and a first adhesive layer. The backlight module is stacked below the second surface of the display module. The backlight module includes a support member having an accommodation cavity inside. The support member is fixed to the second surface, and the second side surface of the support member surrounds the accommodation cavity. The display module is fixedly assembled with the support member located below the display module. Compared with the display screen in the related art, the support member of the backlight module is not arranged around the periphery of the display module, there is no gap between the support member and the peripheral side surface (the first side surface) of the display module, the second side surface of the support member can be arranged approximately flush with the first side surface, and the display screen does not need to be provided with a mylar glue member to cover the side plate, the edge of the display module, and the gap between the side plate and the display module. The width of the black border area is the distance from the second side surface of the support member to the display area. Compared with the width of the black border area of the display screen in the related art, at least the thickness of the mylar glue member, the thickness of the side plate, and the gap between the side plate and the peripheral side surface of the display module are reduced, the width of the black border area of the display screen is significantly reduced, the black border area of the display screen is narrowed, the screen occupation ratio of the display screen is increased, the demand of users for large-screen display is met, and the visual experience is improved.

[0094] And the first adhesive layer plays an auxiliary connection role, strengthening the fixed assembly strength of the display module and the backlight module. The first adhesive layer is a light-shielding layer and also plays a light-shielding role, avoiding light leakage from the first side surface of the display module and improving the display effect. And the first adhesive layer covers the first side surface and the second side surface and does not cover the display surface of the display module, and the visual consistency and delicacy on the display surface side of the display screen are relatively high. When assembled into an electronic device, there is no need to provide a light-shielding structure to block the mylar glue member, improving the visual consistency and delicacy of the whole electronic device, and also being able to reduce the space occupied by the light-shielding structure in the thickness direction, facilitating the thinning of the electronic device, and reducing the number of components of the electronic device, which is beneficial to reducing costs and weight.

[0095] Figure 3 It is a cross-sectional schematic diagram of a display screen provided by an embodiment of the present application.

[0096] See Figure 3 As shown, the display screen 11 includes a display module 111 and a backlight module 112. The display module 111 may include a first side surface 111a, a first surface 111b, and a second surface 111c. Among them, the first surface 111b and the second surface 111c may be located on opposite sides of the display module 111. For example, the surfaces on opposite sides of the display module 111 in the thickness direction (such as the z direction) may be the first surface 111b and the second surface 111c respectively. The first side surface 111a may be located between the first surface 111b and the second surface 111c. The first side surface 111a may be an approximately annular surface, and the first side surface 111a may surround the first surface 111b and the second surface 111c.

[0097] Exemplarily, the overall outer contour shape of the display module 111 can be plate-like. The first surface 111b and the second surface 111c are two surfaces on opposite sides of the display module 111, such as the two relatively larger surfaces on opposite sides of a plate-like structure. The first side surface 111a can be the peripheral side surface of the entire display module 111, surrounding the circumference of the display module 111, such as the four peripheral surfaces surrounding the periphery of a plate-like structure.

[0098] Among them, the first surface 111b can be used as the display surface of the display module 111 and the display screen 11, and images, videos, etc. can be displayed on the first surface 111b.

[0099] The backlight module 112 can be stacked below the second surface 111c of the display module 111. For example, in the thickness direction (such as the z direction), the backlight module 112 can be located below the side of the second surface 111c facing away from the first surface 111b. The backlight module 112 does not surround the periphery of the display module 111, and the backlight module 112 does not have a part that surrounds the periphery of the display module 111.

[0100] Exemplarily, the backlight module 112 can include a support member 112a and a backlight assembly 112b. The backlight assembly 112b can provide light. For example, in some examples, the backlight assembly 112b can include a light source, a light guide plate, a reflective layer, a brightness enhancement film layer, etc. The specific composition of the backlight assembly 112b is not limited in the embodiments of the present application.

[0101] Among them, the backlight assembly 112b can include a third surface and a fourth surface. The third surface and the fourth surface can be located on opposite sides of the backlight assembly 112b. For example, the surfaces on opposite sides of the backlight assembly 112b in the thickness direction (such as the z direction) can be the third surface and the fourth surface respectively. The peripheral side surface 1120b of the backlight assembly 112b can be located between the third surface and the fourth surface and is arranged to surround the third surface and the fourth surface.

[0102] For example, the overall outer contour shape of the backlight assembly 112b can be plate-like. The third surface and the fourth surface can be two surfaces on opposite sides of the backlight assembly 112b. The peripheral side surface 1120b of the backlight assembly 112b can be the four peripheral surfaces surrounding the periphery of a plate-like structure.

[0103] The support member 112a can provide support for the backlight assembly 112b, the display module 111 above the backlight module 112, etc. An accommodation cavity 112c can be formed inside the support member 112a, and the side of the accommodation cavity 112c facing the display module 111 can have an opening. The backlight assembly 112b can be disposed in the accommodation cavity 112c, and the light-emitting surface of the backlight assembly 112b can face the opening, ensuring that the light emitted by the backlight assembly 112b can irradiate the display module 111.

[0104] The support member 112a can also play a role in shielding the backlight assembly 112b, preventing light from leaking out from the peripheral side surface 1120b of the backlight assembly 112b and affecting the display effect.

[0105] The support member 112a can include a second side surface 1120a, which can be disposed around the accommodation cavity 112c. The second side surface 1120a can serve as the peripheral side surface of the support member 112a and surround the circumference of the support member 112a.

[0106] Both the support member 112a and the backlight assembly 112b are located below the second surface 111c of the display module 111. The second surface 111c of the display module 111 can be fixed to the support member 112a located below the display module 111, realizing a stable assembly between the display module 111 and the backlight module 112, so that the display module 111 and the backlight module 112 can form an integral component. The support member 112a and the backlight module 112 can support and fix the display module 111.

[0107] In this way, the backlight module 112 is stacked below the second surface 111c of the display module 111, and the display module 111 is fixed to the support member 112a located below the display module 111. Compared with the display screen 200 in the above related art, the support member 112a of the backlight module 112 is not disposed around the periphery of the display module 111, and there may be no such gap between the support member 112a and the peripheral side surface (i.e., the first side surface 111a) of the display module 111. The second side surface 1120a of the support member 112a can be approximately flush with the first side surface 111a of the display module 111, that is, the connection between the first side surface 111a and the second side surface 1120a can be approximately a smooth surface, and the display screen does not need to be provided with the above-mentioned mylar glue parts to cover the side plates, the edges of the display module, and the gaps between the side plates and the display module.

[0108] The black border area 117 of the display screen 11 can be the area between the second side 1120a (or the first side 111a) of the support member 112a and the display area of the display screen 11 (taking the AA area as an example). The width of the black border area can be the distance between the second side 1120a (or the first side 111a) of the support member 112a and the display area (such as the AA area) (such as the distance in the y direction in the figure), as shown by D2 in the figure. Compared with the width of the black border area of the display screen 200 in the related art, at least the thickness of the mylar glue part (such as the thickness in the y direction), the thickness of the side plate (such as the thickness in the y direction), and the gap between the side plate and the peripheral side surface of the display module (such as the distance in the y direction) are reduced, significantly reducing the width of the black border area 117 of the display screen 11, achieving the narrowing of the black border area of the display screen 11, improving the screen occupation ratio of the display screen 11, meeting the user's demand for large-screen display, and enhancing the visual experience.

[0109] The display screen 11 further includes a first adhesive layer 113. The first adhesive layer 113 can cover the first side 111a of the display module 111 and the second side 1120a of the support member 112a, enabling the display module 111 to be fixed to the support member 112a through the first adhesive layer 113. The first adhesive layer 113 plays an auxiliary connection role and strengthens the fixed assembly strength between the display module 111 and the backlight module 112.

[0110] The first adhesive layer 113 is a light-shielding layer, that is, the first adhesive layer 113 can be a film layer with low light transmittance or no light transmittance. For example, the first adhesive layer 113 can be an opaque adhesive layer, which can play a light-shielding role to prevent light from leaking out from the first side 111a of the display module 111 and improve the display effect.

[0111] The purpose of preventing light leakage and strengthening the assembly fastness between the display module 111 and the backlight module 112 is achieved through the first adhesive layer 113. Compared with the mylar glue part of the display screen 200 in the related art, the first adhesive layer 113 covers the first side 111a and the second side 1120a and does not cover the display surface (i.e., the first surface 111b) of the display module 111. The visual consistency and delicacy on the display surface side of the display screen 11 are relatively high.

[0112] And when assembling into the electronic device 100, there is no need to set a light-shielding structure to block the mylar glue part, improving the visual consistency and delicacy of the whole electronic device 100. It can also reduce the occupied space of the light-shielding structure in the thickness direction (such as the z direction), which is beneficial to the thinning of the electronic device 100. And it also reduces the number of components of the electronic device 100, which is beneficial to cost reduction and weight reduction.

[0113] In some examples, the first adhesive layer 113 can completely cover the first side 111a of the display module 111, which can effectively prevent light from leaking out of the first side 111a of the display module 111, achieving a good light leakage prevention effect and being conducive to improving the display effect of the display screen 11.

[0114] The first adhesive layer 113 can cover at least a part of the second side 1120a of the support member 112a. Exemplarily, for example, the first adhesive layer 113 can only cover a part of the second side 1120a. Under the condition of ensuring a high assembly fastness between the display module 111 and the support member 112a, the size of the first adhesive layer 113 can be reduced, which is conducive to cost reduction and weight reduction.

[0115] Exemplarily, the first adhesive layer 113 can be a film layer formed by using a viscous colloidal material, and this colloidal material is light-impermeable or has poor light transmittance. For example, a light-impermeable glue, adhesive or other colloidal material can be placed on the first side 111a and the second side 1120a by means of dispensing to form the first adhesive layer 113.

[0116] That is, the first adhesive layer 113 can be directly formed on the first side 111a and the second side 1120a. For the display screen 200 using a mylar glue part in the related art, it is necessary to first form the mylar glue part, then cut the mylar glue part into the required shape, size, etc., and then paste the mylar glue part on the display module and the support member. Therefore, compared with the display screen 200 in the related art, the first adhesive layer 113 can be directly formed on the first side 111a and the second side 1120a by means of dispensing, etc. The forming method is simple and convenient, which is conducive to simplifying the assembly process of the display screen 11.

[0117] In some examples, the range of the width D2 of the black edge area 117 of the display screen 11 can include 1.7 mm to 1.9 mm. The width of the black edge area 117 of the display screen 11 is relatively small. Compared with the display screen 200 in the related art above, the width of the black edge area 117 is reduced by about 0.6 mm, which well realizes the black edge narrowing design of the display screen 11, enables the display screen 11 to have a larger screen occupation ratio, and significantly improves the visual experience.

[0118] It should be noted that the first side 111a and the second side 1120a are approximately flush. After the display module 111 and the backlight module 112 are assembled, the first side 111a and the second side 1120a are almost on the same plane, there is no obvious gap between the first side 111a and the second side 1120a, the first side 111a and the second side 1120a are connected to form a basically smooth plane, and there is no obvious height difference (such as the height difference in the y direction) between the first side 111a and the second side 1120a.

[0119] For example, taking the peripheral side surface 1120b of the backlight assembly 112b as a reference datum plane, the distance between the first side surface 111a and the peripheral side surface 1120b of the backlight assembly 112b (such as the distance in the y direction) and the distance between the second side surface 1120a and the peripheral side surface 1120b of the backlight assembly 112b (such as the distance in the y direction) can be approximately equal.

[0120] In some examples, the distance range between the first side surface 111a and the second side surface 1120a can include 0 mm to 0.05 mm. Within a certain assembly and production processing tolerance range, it is ensured that after the display module 111 and the backlight module 112 are assembled, the first side surface 111a and the second side surface 1120a can achieve an approximately flush effect. Thereby, it can be ensured that the width of the black border area 117 of the display screen 11 is further reduced, realizing the further narrowing of the black border area 117 of the display screen 11, which is convenient for processing and assembly.

[0121] It should be noted that when there is a non-zero distance between the first side surface 111a and the second side surface 1120a, it can be that the first side surface 111a protrudes from the second side surface 1120a, or it can also be that the second side surface 1120a protrudes from the first side surface 111a. For example, the distance between the first side surface 111a and the peripheral side surface 1120b of the backlight assembly 112b can be slightly greater than the distance between the second side surface 1120a and the peripheral side surface 1120b of the backlight assembly 112b, or the distance between the first side surface 111a and the peripheral side surface 1120b of the backlight assembly 112b can be slightly less than the distance between the second side surface 1120a and the peripheral side surface 1120b of the backlight assembly 112b.

[0122] In some examples, the first side surface 111a and the second side surface 1120a are arranged flush, that is, the first side surface 111a and the second side surface 1120a can be located on the same plane, the first side surface 111a and the second side surface 1120a are connected to form a plane, and the distance between the first side surface 111a and the second side surface 1120a can be 0 mm. For example, the distance between the first side surface 111a and the peripheral side surface 1120b of the backlight assembly 112b can be equal to the distance between the second side surface 1120a and the peripheral side surface 1120b of the backlight assembly 112b. It can better reduce the width of the black border area 117 of the display screen 11, making the display screen 11 have a narrower black border area 117.

[0123] In some examples, as Figure 3 shown in, the display module 111 can include a polarizer 1112 and a display panel 1111. The polarizer 1112 can be located on the side of the display panel 1111 facing away from the display module 111, that is, the display panel 1111 can be located between the polarizer 1112 and the backlight module 112.

[0124] Among them, one side of the polarizer 1112 facing away from the display panel 1111 can be used as the first surface 111b of the display module 111, and one side of the display panel 1111 facing away from the polarizer 1112 can be used as the second surface 111c of the display module 111. The display panel 1111 can be fixed to the support member 112a located below the display panel 1111.

[0125] Exemplarily, the outer contour shape of the polarizer 1112 can be plate-like, and the peripheral side surface 1112a of the polarizer 1112 can be a peripheral surface surrounding the circumference of the polarizer 1112. The peripheral side surface 1112a of the polarizer 1112 is disposed around the first surface 111b.

[0126] The display panel 1111 can include a glass substrate, a liquid crystal structure sandwiched between the glass substrates, a filter, etc. The outer contour shape of the display panel 1111 can also be plate-like. The peripheral side surface 1111a of the display panel 1111 can be a peripheral surface surrounding the entire circumference of the display panel 1111. The peripheral side surface 1111a of the display panel 1111 is disposed around the second surface 111c. The peripheral side surface 1112a of the polarizer 1112 and the peripheral side surface 1111a of the display panel 1111 can jointly form the first side surface 111a of the display module 111.

[0127] In some examples, the peripheral side surface 1111a of the display panel 1111 and the peripheral side surface 1112a of the polarizer 1112 can be approximately flush. After assembling the display panel 1111 and the polarizer 1112, the peripheral side surface 1111a of the display panel 1111 and the peripheral side surface 1112a of the polarizer 1112 can be almost in the same plane, and there is no obvious spacing and height difference (such as the height difference in the y direction) between the peripheral side surface 1111a of the display panel 1111 and the peripheral side surface 1112a of the polarizer 1112.

[0128] For example, still taking the peripheral side surface 1120b of the backlight assembly 112b as the reference datum plane, the spacing (such as the spacing in the y direction) between the peripheral side surface 1112a of the polarizer 1112 and the peripheral side surface 1120b of the backlight assembly 112b can be approximately equal to the spacing (such as the spacing in the y direction) between the peripheral side surface 1111a of the display panel 1111 and the peripheral side surface 1120b of the backlight assembly 112b. This is beneficial to further improving the visual consistency and delicacy of the display screen 11 on the display surface side (the first surface 111b side), and improving the appearance of the display screen 11 and the entire electronic device 100.

[0129] In some examples, the spacing range between the peripheral side surface 1111a of the display panel 1111 and the peripheral side surface 1112a of the polarizer 1112 may include 0 mm to 0.25 mm. Within a certain assembly and production processing tolerance range, it is ensured that the peripheral side surfaces of the display panel 1111 and the polarizer 1112 can achieve an approximately flush effect after assembly, which is convenient for processing and assembly implementation.

[0130] It should be noted that when there is a non-zero spacing between the peripheral side surface 1111a of the display panel 1111 and the peripheral side surface 1112a of the polarizer 1112, it may be that the peripheral side surface 1111a of the display panel 1111 protrudes from the peripheral side surface 1112a of the polarizer 1112, or alternatively, it may be that the peripheral side surface 1112a of the polarizer 1112 protrudes from the peripheral side surface 1111a of the display panel 1111.

[0131] For example, the spacing between the peripheral side surface 1111a of the display panel 1111 and the peripheral side surface 1120b of the backlight assembly 112b may be slightly greater than the spacing between the peripheral side surface 1112a of the polarizer 1112 and the peripheral side surface 1120b of the backlight assembly 112b, or alternatively, the spacing between the peripheral side surface 1111a of the display panel 1111 and the peripheral side surface 1120b of the backlight assembly 112b may be slightly less than the spacing between the peripheral side surface 1112a of the polarizer 1112 and the peripheral side surface 1120b of the backlight assembly 112b.

[0132] In some examples, the peripheral side surface 1111a of the display panel 1111 and the peripheral side surface 1112a of the polarizer 1112 are arranged flush, that is, the peripheral side surface 1111a of the display panel 1111 and the peripheral side surface 1112a of the polarizer 1112 may be located on the same plane, and the formed first side surface 111a may be a smooth plane, and the spacing between the peripheral side surface 1111a of the display panel 1111 and the peripheral side surface 1112a of the polarizer 1112 may be 0 mm. This makes the display screen 11 have higher visual consistency and refinement, and is more conducive to improving the appearance of the display screen 11 and the entire electronic device 100.

[0133] In some examples, the display screen 11 may further include a protective layer 115, and the protective layer 115 may be disposed above the first surface 111b of the display module 111. For example, along the thickness direction (such as the z direction), the protective layer 115 may be located above the side of the first surface 111b facing away from the second surface 111c, and the protective layer 115 may cover the first surface 111b of the display module 111, playing a protective role for the display module 111, reducing or avoiding damage such as scratches and fractures caused by external impacts, pressures, etc. to the display module 111, and improving the stability and reliability of the display screen 11.

[0134] Among them, the protective layer 115 can be fixed to the display module 111 through the first adhesive layer 113. By using the first adhesive layer 113, the protective layer 115 is fixed to the display module 111 and the backlight module 112, so that the entire display screen 11 can be assembled into an integral structural member, facilitating the assembly of the display screen 11 with a housing (such as the second housing). Moreover, there is no need to additionally provide an adhesive layer or the like to connect the protective layer 115 and the display module 111, which is beneficial to reducing the number of components of the display screen 11, reducing costs, and reducing weight.

[0135] The protective layer 115 can also be a film layer with specific functions. For example, the protective layer 115 can include, but is not limited to, a film layer with functions such as waterproofing, dustproofing, and explosion-proofing, which can endow the display screen 11 with certain dustproof, waterproof, and explosion-proof properties, and better protect the film layers and structural members below the protective layer 115.

[0136] In some examples, the protective layer 115 can be provided to protrude from the first side surface 111a of the display module 111. For example, the outer contour shape of the protective layer 115 can be plate-like, and the peripheral side surface 115a of the protective layer 115 can be a peripheral surface that surrounds the circumference of the protective layer 115.

[0137] There can be a spacing between the peripheral side surface 115a of the protective layer 115 and the first side surface 111a, and the peripheral side surface 115a of the protective layer 115 can be higher than the second side surface 1120a. For example, along the y direction, the peripheral side surface 115a of the protective layer 115 can be higher than the second side surface 1120a. For example, still taking the peripheral side surface 1120b of the backlight assembly 112b as a reference datum plane, the spacing between the peripheral side surface 115a of the protective layer 115 and the peripheral side surface 1120b of the backlight assembly 112b can be greater than the spacing between the first side surface 111a and the peripheral side surface 1120b of the backlight assembly 112b.

[0138] A part of the first adhesive layer 113 can cover the surface of the protective layer 115 facing the display module 111, and the first adhesive layer 113 covers (partially or completely) the part of the protective layer 115 that protrudes from the display module 111. Thus, the first adhesive layer 113 can connect and assemble the protective layer 115, the display module 111, and the support member 112a together.

[0139] That is, along the thickness direction (such as the z direction), the first adhesive layer 113 is located below the surface of the protective layer 115 facing the display module 111. Compared with the situation where the first adhesive layer 113 is located above the peripheral side surface 115a of the protective layer 115 or the surface of the protective layer 115 facing away from the display module 111, the protective layer 115 can play a certain shielding effect on the first adhesive layer 113. This is beneficial to further improving the consistency and delicacy of the display screen 11 on the display surface side and enhancing the appearance of the display screen 11.

[0140] In addition, the protective layer 115 protruding from the display module 111 can also play a better protective role for the display module 111, the first adhesive layer 113, etc., reducing or avoiding damages such as the detachment and cracking of the first adhesive layer 113, and ensuring the assembly firmness and stability of the display module 111, the protective layer 115 and the backlight module 112, which is conducive to achieving the high stability and reliability of the display screen 11.

[0141] Exemplarily, the height range of the protective layer 115 protruding from the first side 111a of the display module 111 may include 0.3 mm to 0.45 mm. This ensures that the protective layer 115 can provide good protection for the first adhesive layer 113, the display module 111, etc., and is conducive to implementing the design of narrowing the black edge area of the display screen 11.

[0142] In some examples, the display screen 11 may further include an occlusion layer 116. The occlusion layer 116 may be located on the side of the protective layer 115 facing the display module 111. A part of the occlusion layer 116 may cover the edge of the first surface 111b, and a part of the occlusion layer 116 may cover the first adhesive layer 113. The occlusion layer 116 can play an occlusion role for the first adhesive layer 113 and the edge where the first adhesive layer 113 meets the first side 111a, which is conducive to improving the appearance effect of the display screen 11.

[0143] Of course, in some other examples, the display screen 11 may not include the above-mentioned protective layer 115 and occlusion layer 116.

[0144] In some examples, the display screen 11 may further include a second adhesive layer 114. The second adhesive layer 114 may be disposed between the support member 112a and the second surface 111c of the display module 111, so that the support member 112a can be adhesively fixed to the display module 111 through the second adhesive layer 114.

[0145] Among them, the material of the second adhesive layer 114 may include a colloidal material. For example, the material of the second adhesive layer 114 may include, but is not limited to, colloidal materials such as glue and adhesive.

[0146] During actual assembly, the backlight assembly 112b may first be disposed in the accommodation cavity 112c of the support member 112a, the second adhesive layer 114 may be formed on the support member 112a, and then the display panel 1111, the polarizer 1112, etc. may be sequentially stacked above the backlight assembly 112b, and the display panel 1111 may be adhesively fixed to the second adhesive layer 114, thereby realizing the fixed assembly of the display module 111 and the backlight module 112. The first side 111a of the display module 111 and the second side 1120a of the backlight module 112 may be approximately flush.

[0147] Then, the protective layer 115 and the shielding layer 116 can be disposed above the display module 111, and the first adhesive layer 113 is formed by means of dispensing or the like, so that a part of the first adhesive layer 113 covers the surface of the protective layer 115 (and the shielding layer 116) facing the display module 111, and a part of the first adhesive layer 113 covers the first side surface 111a and the second side surface 1120a of the display module 111, strengthening the assembly fastness between the protective layer 115, the display module 111 and the backlight module 112, and forming an integral component of the display screen 11. Then, the display screen 11 is assembled and fixed with a housing (such as the second housing) to assemble an electronic device.

[0148] Figure 4 For Figure 3 is a schematic cross-sectional view of the assembly structure between the display screen and the housing in

[0149] Exemplarily, referring to Figure 4 shown, the electronic device may include a third adhesive layer 14. The display screen 11 may be disposed in an assembly cavity of a housing (such as the second housing 12). The third adhesive layer 14 may be disposed between the inner surface of the housing (the surface facing the assembly cavity) and the display screen 11. For example, the third adhesive layer 14 may be located between the second housing 12 and the support member 112a of the display screen 11, so that the display screen 11 can be fixedly assembled with the second housing 12 through the third adhesive layer 14.

[0150] Wherein, the material of the third adhesive layer 14 may include a colloidal material. For example, the material of the third adhesive layer 14 may include, but is not limited to, colloidal materials such as easy-pull glue, glue, and adhesive.

[0151] In some examples, as Figure 4 shown, the electronic device may further include an annular member 13, such as a ring. The annular member 13 may surround the inner side of the second housing 12 and surround the periphery of the display screen 11. The annular member 13 can play roles such as strengthening the strength of the second housing 12 and protecting the edge of the display screen 11.

[0152] Hereinafter, taking the display screen 11 including the protective layer 115 and the shielding layer 116 as an example, the structure of the support member 112a of the backlight module 112 and the assembly manner between the support member 112a and the display module 111 are exemplarily described. The structure of the support member 112a and the assembly manner with the display module 111 in the following text can be applied to the display screen 11 in any of the above examples.

[0153] Exemplarily, referring to Figure 4As shown, the support member 112a may include a bottom wall 1121 and a side wall 1122. Among them, the bottom wall 1121 may be a plate-like structural member, and the side wall 1122 may be a frame-like structural member. The outer contour shape of the side wall 1122 may be annular-like, and the side wall 1122 may be disposed around one side of the bottom wall 1121 facing the display module 111.

[0154] The side wall 1122 and the bottom wall 1121 may enclose the above-mentioned accommodation cavity 112c of the support member 112a. One end of the side wall 1122 away from the bottom wall 1121 may enclose an opening communicating with the accommodation cavity 112c. One side of the side wall 1122 facing away from the accommodation cavity 112c may form the above-mentioned second side surface 1120a of the support member 112a.

[0155] The second adhesive layer 114 may be located between the end surface of one end of the side wall 1122 away from the bottom wall 1121 and the second surface 111c of the display module 111, so that the side wall 1122 can be fixedly connected to the display module 111 through the second adhesive layer 114, thereby realizing the stable assembly of the display module 111 and the backlight module 112. The structural design of the support member 112a is simple, and the assembly method between the support member 112a and the display module 111 is simple, which is convenient for processing and assembly.

[0156] In some examples, as Figure 4 shown, the side wall 1122 may include a first wall body 1122a and an extension structure 1122b. Among them, the first wall body 1122a may include an opposite first end and a second end. For example, the first end and the second end may be respectively located on both sides of the first wall body 1122a in the thickness direction (such as the z direction). The first end of the first wall body 1122a may be fixed to the bottom wall 1121.

[0157] The extension structure 1122b may be disposed on the second end of the first wall body 1122a, and the extension structure 1122b may protrude from one side of the first wall body 1122a facing the accommodation cavity 112c. Exemplarily, one end of the extension structure 1122b may be fixed to the second end of the first wall body 1122a, and the other end of the extension structure 1122b may extend a certain length away from the second end of the first wall body 1122a (such as extending a certain length in the y direction).

[0158] For example, taking the second side surface 1120a as a reference datum plane, the distance between the end surface of the other end of the extension structure 1122b and the second side surface 1120a (such as the distance in the y direction) is greater than the distance between one side of the first wall body 1122a facing the accommodation cavity 112c and the second side surface 1120a, so that the extension structure 1122b can be higher than one side of the first wall body 1122a facing the accommodation cavity 112c.

[0159] The second adhesive layer 114 may be located between the extension structure 1122b and the display module 111, so that the support member 112a is adhesively fixed to the second surface of the display module 111 through the extension structure 1122b. The extension length of the extension structure 1122b (such as the extension length in the y direction) is relatively large, so that the second adhesive layer 114 can have a relatively large occupied area, which is beneficial to increasing the adhesive area between the support member 112a and the display module 111, and improving the assembly firmness and support strength between the support member 112a and the display module 111.

[0160] In addition, compared with the display screen 200 in the related art, the support member 112a is assembled and fixed by adhesively bonding the extension structure 1122b of the support member 112a to the display module 111. There is no need to provide a plastic part in the accommodation cavity 112c of the support member 112a, which can reduce the occupied space of the plastic part, and is beneficial to narrowing the distance between the side wall 1122 of the support member 112a and the peripheral side surface of the backlight assembly 112b, and can further reduce the width of the black edge area.

[0161] Exemplarily, the materials of the first wall body 1122a, the extension structure 1122b and the bottom wall 1121 may be metals, such as iron metal, etc., and may have good mechanical properties and strength.

[0162] In some examples, the first wall body 1122a and the extension structure 1122b may be an integral structural member, that is, the first wall body 1122a and the extension structure 1122b may be formed into an integral structural member by an integral molding method, and the side wall 1122 may be an integral structural member. This is beneficial to enhancing the mechanical properties and strength of the extension structure 1122b, improving the assembly stability between the support member 112a and the display module 111, and is beneficial to improving the support strength of the support member 112a for the display module 111, thereby enhancing the stability and reliability of the display screen 11.

[0163] For example, a plate-shaped metal base material can be used, and one end portion of the metal base material can be bent into an L-shape by stamping or the like to form an integral structural member of the first wall body 1122a and the extension structure 1122b.

[0164] Of course, in some examples, the first wall body 1122a and the extension structure 1122b may also be two separate structural members. After the first wall body 1122a and the extension structure 1122b are respectively formed, the extension structure 1122b can be fixedly arranged on the second end of the first wall body 1122a by means of adhesive connection, threaded connection, snap connection, welding connection, etc.

[0165] In some examples, the first wall 1122a and the bottom wall 1121 can be an integral structural member, that is, the first wall 1122a and the bottom wall 1121 can be formed into an integral structural member by an integral molding method. This is beneficial to improving the mechanical properties and strength of the first wall 1122a and the entire side wall 1122, and improving the assembly stability of the support member 112a and the display module 111 and the support strength of the support member 112a for the display module 111.

[0166] In an example where the first wall 1122a and the bottom wall 1121 are an integral structural member, the first wall 1122a and the extension structure 1122b can also be an integral structural member, that is, the entire support member 112a can be an integral structural member, making the support member 112a as a whole have higher mechanical properties and strength.

[0167] Exemplarily, the material of the support member 112a can be metal. A plate-shaped metal base material can be used, and by means such as stamping, a transition member in a shape similar to an L shape can be formed first. The transition member can include an intersecting first part and a second part, the second part protrudes from the first part, and the first part can form the bottom wall 1121. Then, by means such as stamping, one end of the second part away from the first part can be bent (bent into the space enclosed by the first part and the second part), so that the second part can form the first wall 1122a and the extension structure 1122b respectively.

[0168] Of course, in an example where the first wall 1122a and the bottom wall 1121 are an integral structural member, the first wall 1122a and the extension structure 1122b can also be two separate structural members.

[0169] Or, in some examples, the first wall 1122a and the bottom wall 1121 can be two separate structural members. After the first wall 1122a and the bottom wall 1121 are formed separately, the first wall 1122a can be fixedly arranged on one surface of the bottom wall 1121 by means such as adhesive connection, threaded connection, snap connection, welding connection, etc.

[0170] It can be understood that in an example where the first wall 1122a and the bottom wall 1121 are separate structural members, the first wall 1122a and the extension structure 1122b can be an integral structural member, or can also be separate structural members.

[0171] It can be understood that as shown in Figure 4 If the extension structure 1122b protrudes from the surface of the first wall 1122a facing the accommodation cavity 112c, there is a gap between the extension structure 1122b and the bottom wall 1121.

[0172] Figure 5 This is a cross-sectional schematic diagram of another assembly structure of a display screen and a housing provided by an embodiment of the present application.

[0173] To further enhance the mechanical properties of the extension structure 1122b, in some examples, refer to Figure 5 As shown, the side wall 1122 may further include a first structural member 1122c.

[0174] The first structural member 1122c may be disposed in the gap between the extension structure 1122b and the bottom wall 1121. The opposite end faces of the first structural member 1122c may be in contact with the extension structure 1122b and the bottom wall 1121 respectively. For example, the opposite end faces of the first structural member 1122c in the thickness direction (such as the z direction) are in contact with the extension structure 1122b and the bottom wall 1121 respectively.

[0175] The first structural member 1122c may fill the gap between the extension structure 1122b and the bottom wall 1121, playing a supporting role for the extension structure 1122b, further enhancing the mechanical properties and strength of the extension structure 1122b, and further improving the assembly stability of the support member 112a and the display module 111 and the support strength of the support member 112a for the display module 111.

[0176] Wherein, the material of the first structural member 1122c may be different from that of the first wall body 1122a (and the extension structure 1122b, the bottom wall 1121), etc. For example, the material of the first structural member 1122c may include but is not limited to plastic. Under the condition of being able to achieve a good supporting effect, it is beneficial to reduce the weight of the support member 112a and the display screen 11, and beneficial to reduce the cost of the display screen 11.

[0177] The first structural member 1122c and the extension structure 1122b (the bottom wall 1121 and the first wall body 1122a) may be split structural members, that is, the first structural member 1122c may be fixed between the extension structure 1122b and the bottom wall 1121 after being formed.

[0178] Or, in some examples, the side wall 1122 may not include the above-mentioned extension structure 1122b.

[0179] Figure 6 This is a schematic cross-sectional structure diagram of another assembly structure of a display screen and a housing provided by an embodiment of the present application.

[0180] Exemplarily, refer to Figure 6 As shown, the side wall 1122 may include a first wall body 1122a and a second structural member 1122d. The first wall body 1122a may be the first wall body in the above text. The first end of the first wall body 1122a may be fixed to the bottom wall 1121.

[0181] The second structural member 1122d may be located inside the first wall 1122a (the side facing the accommodation cavity 112c), the second structural member 1122d is disposed closer to the accommodation cavity 112c of the support member 112a, and the second structural member 1122d may be disposed in contact with the inner side surface (the surface facing the accommodation cavity 112c) of the first wall 1122a.

[0182] A part of the second adhesive layer 114 may be located between the second structural member 1122d and the display module 111, and a part of the second adhesive layer 114 may be located between the second end of the first wall 1122a and the display module 111. That is, a part of the second adhesive layer 114 covers one end of the second structural member 1122d away from the bottom wall 1121, and a part of the second adhesive layer 114 covers one end of the first wall 1122a away from the bottom wall 1121, so that the first bottom wall 1121 and the second structural member 1122d are both adhesively fixed to the display module 111 through the second adhesive layer 114.

[0183] The arrangement of the second structural member 1122d can increase the extension length of the entire side wall 1122 (such as the extension length in the y direction), so that the second adhesive layer 114 can have a larger occupied area, increasing the adhesive area between the support member 112a and the display module 111, which is beneficial to improving the assembly firmness and support strength between the support member 112a and the display module 111.

[0184] In addition, the second structural member 1122d is disposed in contact with the inner side surface of the first wall 1122a. Under the condition of increasing the adhesive area, it is beneficial to reduce the distance between the second structural member 1122d and the first wall 1122a, so as to be able to reduce the distance between the second structural member 1122d (or the entire side wall 1122) and the peripheral side surface of the backlight assembly 112b, and further reduce the width of the black border area.

[0185] Wherein, the second structural member 1122d may be fixed to one of the first wall 1122a and the bottom wall 1121. For example, the second structural member 1122d may be fixedly attached to the first wall 1122a and the bottom wall 1121 respectively, so that the second structural member 1122d and the first wall 1122a have high mechanical properties and strength.

[0186] Of course, in some other examples, the second structural member 1122d may be fixed only to the first wall 1122a, or the second structural member 1122d may also be fixed only to the bottom wall 1121.

[0187] In the embodiments of the present application, the manner of fixing the second structural member 1122d to the first wall 1122a and / or the bottom wall 1121 is not limited. For example, the second structural member 1122d may be fixed to the first wall 1122a and / or the bottom wall 1121 by means of adhesive connection, screw connection, snap connection, etc.

[0188] The material of the second structural member 1122d may be different from that of the first wall 1122a (and the extended structure 1122b, the bottom wall 1121), etc. For example, the material of the second structural member 1122d may include, but is not limited to, plastic. Under the condition that it can achieve a good supporting effect, it is beneficial to reduce the weight of the support member 112a and the display screen 11, and is beneficial to reducing costs.

[0189] Figure 7 It is a schematic cross-sectional view of another display screen and housing assembly structure provided by an embodiment of the present application.

[0190] Or, in some examples, as shown in Figure 7 The side wall 1122 may include a first wall 1122a and a second structural member 1122g. Among them, the first wall 1122a may be the first wall in the above text, and the first end of the first wall 1122a may be fixed to the bottom wall 1121.

[0191] The second structural member 1122g may include a first split part 1122e and a second split part 1122f. Among them, the first split part 1122e is connected to the second split part 1122f. The second split part 1122f may be located inside the first wall 1122a (on the side facing the accommodation cavity 112c), and the second split part 1122f may be attached to the inner side surface of the first wall 1122a. The second split part 1122f is arranged closer to the accommodation cavity 112c of the support member 112a.

[0192] A part of the first split part 1122e may be fixed to the end of the second split part 1122f away from the bottom wall 1121, and a part of the first split part 1122e may cover (partially or completely cover) the end face of the second split part 1122f away from the bottom wall 1121. A part of the first split part 1122e may be fixed to the second end of the first wall 1122a, and a part of the first split part 1122e may cover (partially or completely cover) the end face of the second end of the first wall 1122a. The cross-sectional outer contour shape of the entire second structural member 1122g may be in the shape of an L.

[0193] The second adhesive layer 114 may be located between the first split part 1122e and the second surface 111c of the display module 111. The first split part 1122e has a relatively wide extension length (such as the extension length in the y direction), which can provide a relatively large layout area for the second adhesive layer 114, can increase the bonding area between the support member 112a and the display module 111, and improve the assembly firmness and support strength between the support member 112a and the display module 111.

[0194] In addition, the second split part 1122f is arranged to fit the inner side surface of the first wall body 1122a. Under the condition of increasing the bonding area, the distance between the second split part 1122f and the first wall body 1122a is reduced, which is conducive to further reducing the distance between the second structural member 1122g (or the entire side wall 1122) and the peripheral side surface of the backlight assembly 112b, and reducing the width of the black edge area.

[0195] Exemplarily, the second split part 1122f can be fixed to one of the first wall body 1122a and the bottom wall 1121. In the embodiment of the present application, the fixing manner of the second split part 1122f to the first wall body 1122a and / or the bottom wall 1121 is not limited. For example, the second split part 1122f can be fixed to the first wall body 1122a and / or the bottom wall 1121 by means of adhesive connection, threaded connection, snap connection, etc. The fixing manner of the first split part 1122e to the first wall body 1122a is also not limited, and it can also be fixedly assembled by the above-exemplified means.

[0196] The first split part 1122e and the second split part 1122f can be an integral structural member, so that the entire second structural member 1122g can be an integral one-piece structural member. Alternatively, the first split part 1122e and the second split part 1122f can also be two split structural members, and can be fixedly assembled together by means of adhesive connection, threaded connection, snap connection, etc. to form the second structural member 1122g.

[0197] The material of the second structural member 1122g can refer to the material of the second structural member 1122d in the above text. For example, it can include but is not limited to plastics, which is conducive to realizing the weight reduction and cost reduction of the display screen 11.

[0198] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "electrical connection" should be understood in a broad sense. For example, it can be a fixed electrical connection, or it can be indirectly connected through an intermediate medium. It can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0199] The terms "first", "second", "third", "fourth", etc. (if any) in the description, claims, and the above drawings of the embodiments of the present application are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.
