It also helps improve the production efficiency of the outer frame. Furthermore, by using extrusion molding to manufacture the outer frame, the dimensional and shape accuracy of the frame can be guaranteed, thereby improving the overall quality of the display device.

[0037] As described in the background section, a display device is an electronic device that converts electronic signals (such as electrical signals, optical signals, digital signals, etc.) into directly perceptible visual information. In related technologies, a display device includes a back panel, a middle frame, a front frame, a backlight module, and a display module. The back panel is a cavity-type back panel formed by die stamping. The middle frame is mounted on the back panel and cooperates with the back panel to form an accommodating cavity. The backlight module is housed within the accommodating cavity. The front frame is located on the side of the middle frame away from the back panel and supports the display module. However, while the above-mentioned display devices can meet display requirements, the large number of components results in a complex structure.

[0038] Reference Figure 1 and Figure 2To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a display device. The display device includes an outer frame 100, a display module 200, a back panel 300, and a backlight module 400. The outer frame 100 has a front side 110 and a back side 120 disposed opposite to each other, and the outer frame 100 is provided with a receiving space 130 extending from the front side 110 to the back side 120. The outer frame 100 is an extruded molded part. The display module 200 is disposed on the front side 110 and is used to display visual information. The back panel 300 is flat and is disposed on the back side 120. The backlight module 400 is located within the receiving space 130 and is disposed on the back panel 300, and is used to emit light toward the display module 200.

[0039] In this embodiment, the display device is a liquid crystal display (LCD); it is understood that the display device can also be an LED display (LED stands for Light-Emitting Diode) or an OLED display (OLED stands for Organic Light-Emitting Diode). The accommodating space 130 is an accommodating cavity extending from the front side 110 to the back side 120. The outer frame 100 is made of aluminum, and the forming process of the outer frame 100 is as follows: raw materials such as aluminum rods are fed into an extruder, pressure is applied by the extruder, causing the raw materials to undergo plastic deformation in the mold, ultimately forming a frame structure with a preset shape and size. The back plate 300 is fixedly installed on the outer frame 100 by connecting screws. It is understood that the back plate 300 can also be installed on the outer frame 100 by connection structures such as snap-fit ​​structures, plug-in structures, screw structures, magnetic structures, or welding structures.

[0040] The display device of this application only requires the outer frame 100 to cooperate with the flat back plate 300 to achieve stable installation of the display module 200 and the backlight module 400, eliminating the need for a front frame and a middle frame. This structural design reduces the number of parts in the display device, simplifies the overall structure, reduces assembly difficulty and cost, and improves assembly efficiency. Furthermore, the flat back plate 300 avoids the need for die-stamping to create a cavity structure, saving on mold costs, reducing processing difficulty, and shortening the processing cycle.

[0041] Meanwhile, the outer frame 100 is an extruded part. This structural design not only allows for the design of molding dies with different structures according to market demands, enabling the rapid production of outer frames 100 of different shapes and sizes, but also meets the design requirements of different display devices. This enhances the adaptability and designability of display devices, shortens processing cycles, and reduces design costs. It also helps improve the production efficiency of the outer frame 100. Furthermore, by using extrusion molding to manufacture the outer frame 100, the dimensional and shape accuracy of the outer frame 100 can be guaranteed, thereby improving the overall quality of the display device. In addition, compared with processes such as stamping, extrusion molding results in less material waste, effectively improving material utilization and reducing production costs.

[0042] Reference Figures 1 to 6 In one embodiment, the outer frame 100 includes a plurality of end-to-end connected frame borders 140. Each frame border 140 includes a frame body 141 and a support structure 142. The frame body 141 has an inner side surface 1411 facing the center of the outer frame 100. The accommodating space 130 is formed by the plurality of inner side surfaces 1411. The support structure 142 is disposed on the inner side surface 1411 and protrudes towards the center of the outer frame 100. The backlight module 400 includes a light-emitting element 410 and a reflective element 420. The light-emitting element 410 is disposed on the back plate 300. The reflective element 420 is disposed on the surface of the light-emitting element 410 away from the back plate 300 and is attached to the support structure 142. The reflective element 420 projects and covers the light-emitting element 410.

[0043] In this embodiment, there are four borders 140, which are connected end to end to form the outer frame 100. Two opposite borders 140 are of the same size and parallel to each other, while adjacent borders 140 are perpendicular. The center of the outer frame 100 refers to its geometric center. The load-bearing structure 142 and the frame body 141 are integrally formed. It can be understood that the load-bearing structure 142 can also be fixedly installed on the inner side 1411 via a connection structure such as a snap-fit ​​structure, plug-in structure, screw structure, magnetic structure, or welding structure.

[0044] The light-emitting element 410 is an LED light-emitting panel, which is fixedly mounted on the surface of the back plate 300 away from the back plate 300 (i.e., the surface of the back plate 300 near the front 110) by connecting screws. The reflector 420 is a reflective sheet, with part of its structure glued to the surface of the light-emitting element 410 away from the back plate 300, and the other part of its structure mounted on the supporting structure 142. It can be understood that the part of the reflector 420 mounted on the supporting structure 142 can be glued to the supporting structure 142. The projection of the reflector 420 completely covers the light-emitting element 410, that is, the projection surface of the reflector 420 onto the back 120 completely covers the projection surface of the light-emitting element 410 onto the back 120.

[0045] On the one hand, the inner sides 1411 of multiple frame bodies 141 are arranged together to form an accommodating space 130, so that multiple frame bodies 141 together constitute a barrier to protect the backlight module 400, thereby enabling the outer frame 100 to block external dust and foreign objects from entering the accommodating space 130, thereby effectively extending the service life of the backlight module 400.

[0046] On the other hand, the load-bearing structure 142 not only provides support for the reflector 420 and improves the installation stability of the reflector 420 within the accommodating space 130, but also eliminates the need for the outer frame 100 to have an additional support bracket for the reflector 420, reducing the number of parts and lowering the manufacturing difficulty and cost of the outer frame 100.

[0047] On the other hand, the reflector 420 projects onto the light-emitting element 410. This structural design not only improves the utilization rate of the light emitted by the light-emitting element 410, but also makes the light distribution more uniform, thereby improving the display effect of the display device.

[0048] Reference Figure 4 , Figure 5 as well as Figure 6 In one embodiment, the reflector 420 includes a first reflective segment 421, a connecting reflective segment 422, and a second reflective segment 423 connected in sequence. The first reflective segment 421 is disposed on the light-emitting element 410, and the second reflective segment 423 is disposed on the surface of the supporting structure 142 away from the back plate 300. The connecting reflective segment 422 is intersecting with the first reflective segment 421 and the second reflective segment 423, and the connecting reflective segment 422 is parallel to the surface of the supporting structure 142 away from the inner side 1411.

[0049] In this embodiment, the first reflective segment 421, the connecting reflective segment 422, and the second reflective segment 423 are integrally molded parts. The first reflective segment 421 is glued to the surface of the light-emitting element 410 away from the back plate 300, and the second reflective segment 423 is mounted and attached to the surface of the supporting structure 142 away from the back plate 300 (i.e., the surface of the supporting structure 142 near the front 110). The second reflective segment 423 is parallel to the first reflective segment 421. The angle between the connecting reflective segment 422 and the first reflective segment 421 is an obtuse angle, and the angle between the connecting reflective segment 422 and the second reflective segment 423 is also an obtuse angle. It can be understood that the angle between the connecting reflective segment 422 and the first reflective segment 421 and the second reflective segment 423 can also be a right angle. The connecting reflective segment 422 is kept in contact with the surface of the supporting structure 142 away from the inner side 1411 to enhance the stability of the connecting reflective segment 422 within the accommodating space 130.

[0050] The first reflective section 421 is directly mounted on the light-emitting element 410, providing a stable fit and initial fixation. The second reflective section 423 is directly mounted on the surface of the supporting structure 142 away from the back plate 300, achieving secondary fixation with the support of the supporting structure 142. Simultaneously, the connecting reflective section 422, parallel to the surface of the supporting structure 142 away from the inner side 1411, works synergistically to ensure a stable assembly relationship between the reflective element 420, the light-emitting element 410, and the supporting structure 142. This effectively reduces the risk of displacement of the reflective element 420 during transportation or use, and improves the installation stability of the reflective element 420.

[0051] Reference Figure 2 , Figure 5 as well as Figure 6 In one embodiment, the reflector 420 includes a first reflective segment 421, a connecting reflective segment 422, and a second reflective segment 423 connected in sequence. The first reflective segment 421 is disposed on the light-emitting element 410, and the second reflective segment 423 is disposed on the surface of the supporting structure 142 away from the back plate 300. The connecting reflective segment 422 is intersecting with the first reflective segment 421 and the second reflective segment 423, and there is an acute angle between the connecting reflective segment 422 and the surface of the supporting structure 142 away from the inner side 1411.

[0052] In this embodiment, the first reflective segment 421, the connecting reflective segment 422, and the second reflective segment 423 are integrally molded parts. The first reflective segment 421 is glued to the surface of the light-emitting element 410 away from the back plate 300, and the second reflective segment 423 is mounted and attached to the surface of the supporting structure 142 away from the back plate 300 (i.e., the surface of the supporting structure 142 near the front 110). The second reflective segment 423 is parallel to the first reflective segment 421. The angle between the connecting reflective segment 422 and the first reflective segment 421 is an obtuse angle, and the angle between the connecting reflective segment 422 and the second reflective segment 423 is also an obtuse angle. It can be understood that the angle between the connecting reflective segment 422 and the first reflective segment 421 and the second reflective segment 423 can also be a right angle. The connecting reflective segment 422 is in partial structural contact with the surface of the supporting structure 142 away from the inner side 1411.

[0053] The first reflective segment 421 is initially fixed by attaching to the light-emitting element 410, while the second reflective segment 423 obtains support from the supporting structure 142. The connecting reflective segment 422 can evenly transfer the support force at the connection point between the connecting reflective segment 422 and the first reflective segment 421 and the second reflective segment 423 to the entire reflective element 420 through its own inclined structure. This reduces uneven local stress on the reflective element 420, lowers the risk of displacement of the reflective element 420 during transportation or use, and improves the installation stability of the reflective element 420.

[0054] Reference Figure 2 and Figure 6 In one embodiment, the backlight module 400 further includes a diffuser 430 and a diaphragm 440. The diffuser 430 is disposed on the surface of the second reflective section 423 away from the back plate 300 and projects onto and covers the light-emitting element 410. The diaphragm 440 is disposed on the surface of the diffuser 430 away from the back plate 300 and projects onto and covers the light-emitting element 410.

[0055] In this embodiment, the diffuser 430 is a diffuser plate, which is mounted and attached to the surface of the second reflective section 423 away from the back plate 300 (i.e., the surface of the second reflective section 423 near the front 110). The diffuser 430 completely covers the light-emitting element 410 in its projection, that is, the projection surface of the diffuser 430 onto the back 120 completely covers the projection surface of the light-emitting element 410 onto the back 120. The diaphragm 440 is a light processing structure that integrates the diffuser film, the brightness enhancement film, and the reflective film into one unit. The diaphragm 440 is mounted and attached to the surface of the diffuser 430 away from the back plate 300 (i.e., the surface of the diffuser 430 near the front 110). The diaphragm 440 completely covers the light-emitting element 410 in its projection, that is, the projection surface of the diaphragm 440 onto the back 120 completely covers the projection surface of the light-emitting element 410 onto the back 120.

[0056] The diffuser 430 and the diaphragm 440 not only optimize the light, making the light projected onto the display module 200 brighter and more evenly distributed, but also improve the display effect.

[0057] Meanwhile, by using the layered assembly structure where the diffuser 430 is mounted on the second reflective section 423 and the diaphragm 440 is mounted on the diffuser 430, the stable installation of multiple components of the backlight module 400 can be achieved without the use of additional fasteners. This reduces the number of parts in the display device, simplifies the structural design of the display device, shortens the assembly process, and reduces manufacturing costs.

[0058] Reference Figures 2 to 4 as well as Figure 6 In one embodiment, the frame 140 further includes a clamping structure 143, which is disposed on the inner side 1411 and protrudes toward the center of the outer frame 100, and is located on the side of the bearing structure 142 near the front face 110; a buffer structure 450 is clamped and fixed between the clamping structure 143 and the backlight module 400.

[0059] In this embodiment, the clamping structure 143 and the frame body 141 are integrally molded parts; the buffer structure 450 is a buffer foam, and the buffer structure 450 is located on the side of the diaphragm 440 of the backlight module 400 away from the back plate 300. Specifically, the surface of the buffer structure 450 near the clamping structure 143 is in contact with the surface of the clamping structure 143 near the back surface 120, and the surface of the buffer structure 450 near the backlight module 400 is in contact with the surface of the diaphragm 440 away from the back plate 300. It can be understood that the buffer structure 450 can also be a buffer rubber, a buffer sponge, or a buffer strip; the buffer structure 450 can also be glued and fixed between the clamping structure 143 and the diaphragm 440 of the backlight module 400.

[0060] The clamping structure 143 and the buffer structure 450 used together enable the backlight module 400 to be stably mounted on the frame body 141, improving the installation stability of the backlight module 400 on the frame body 141. At the same time, the buffer structure 450 also absorbs impact and vibration, effectively protecting the backlight module 400 and extending its service life.

[0061] Reference Figure 2 , Figure 4 as well as Figure 5 In one embodiment, the surface of the supporting structure 142 away from the inner side 1411 is provided with an avoidance groove 1421, and part of the structure of the light-emitting element 410 is embedded in the avoidance groove 1421.

[0062] In this embodiment, the clearance groove 1421 extends to the surface of the support structure 142 near the back surface 120, and the surface of the light-emitting element 410 near the back surface 120 is located in the clearance groove 1421 and is flush with the surface of the support structure 142 near the back surface 120; it can be understood that the surface of the light-emitting element 410 near the back surface 120 may also extend outside the clearance groove 1421.

[0063] Part of the structure of the light-emitting element 410 is embedded in the clearance groove 1421. This structural design allows the light-emitting element 410 to not protrude from the surface of the support structure 142, but to form a compact spatial fit with the support structure 142 by embedding, thereby reducing the superposition size of the light-emitting element 410 and the support structure 142 in the direction perpendicular to the back surface 120, and thus reducing the thickness of the entire display device.

[0064] Meanwhile, compared to the light-emitting element 410 being directly mounted on the surface of the supporting structure 142, embedding part of the structure of the light-emitting element 410 into the clearance groove 1421 can not only provide a wrap-around protection for the light-emitting element 410, thereby extending the service life of the light-emitting element 410, but also enhance the assembly firmness between the light-emitting element 410 and the supporting structure 142, reducing the risk of the light-emitting element 410 loosening due to external impact or temperature changes.

[0065] Reference Figure 2 In one embodiment, the display module 200 includes a display element 210 and a transparent protective element 220. The transparent protective element 220 is disposed on the frame body 141, and the display element 210 is disposed on the side of the transparent protective element 220 near the back surface 120.

[0066] In this embodiment, the display element 210 is a liquid crystal screen, and the transparent protective element 220 is tempered glass. The projection of the transparent protective element 220 completely covers the display element 210, that is, the projection surface of the transparent protective element 220 onto the back surface 120 completely covers the projection surface of the display element 210 onto the back surface 120. It can be understood that the transparent protective element 220 can also be a transparent film or a transparent plate.

[0067] The transparent protective component 220 not only serves to support and mount the display component 210, but also ensures the visibility of the display component 210, thus guaranteeing a good visual experience. Furthermore, the transparent protective component 220 also acts as a protective barrier for the display module 200, preventing direct damage to the display component 210 from external dust, water stains, or scratches, thereby extending the service life of the display component 210.

[0068] Reference Figure 2 and Figure 7In one embodiment, the display module 200 further includes a touch control 230, which is located between the display element 210 and the transparent protective element 220 and is disposed on the frame body 141; the touch control 230 and the frame body 141 are connected by an adhesive structure 240.

[0069] In this embodiment, the touch control 230 is a capacitive touch film. The touch control 230 is adhesively attached to the side of the transparent protective member 220 near the back surface 120, and the display member 210 is adhesively attached to the side of the touch control 230 near the back surface 120. The projection of the transparent protective member 220 completely covers the touch control 230, that is, the projection surface of the transparent protective member 220 onto the back surface 120 completely covers the projection surface of the touch control 230 onto the back surface 120. The projection of the touch control 230 completely covers the display member 210, that is, the projection surface of the touch control 230 onto the back surface 120 completely covers the projection surface of the display member 210 onto the back surface 120. The adhesive structure 240 is double-sided adhesive, that is, the adhesive structure 240 is adhesive to both the touch control 230 and the frame body 141.

[0070] On the one hand, the touch control 230 enables the display device to have touch functionality, improving the convenience and intuitiveness of user operation.

[0071] On the other hand, the touch control 230 is connected to the frame body 141 via the adhesive structure 240, which not only simplifies the connection structure and reduces the dependence on components, but also improves the connection strength between the touch control 230 and the frame body 141. Furthermore, there is no need to reserve additional space for fasteners, which can maximize the compression of the display module 200's dimensions in the thickness direction of the display device. In addition, the adhesive structure 240 can also form a sealing barrier at the connection point between the touch control 230 and the frame body 141, reducing the entry of external dust and moisture into the housing space 130, improving the sealing performance between the display module 200 and the frame 140, and protecting the components within the housing space 130.

[0072] Reference Figures 2 to 4 as well as Figure 7 In one embodiment, the display module 200 further includes a touch control 230, which is located between the display component 210 and the transparent protective component 220 and is disposed on the frame body 141; the frame body 141 is used to set the surface of the touch control 230 to be a rough surface 1412.

[0073] In this embodiment, the touch control 230 is a capacitive touch film. The touch control 230 is glued to the side of the transparent protective member 220 near the back surface 120, and the display member 210 is glued to the side of the touch control 230 near the back surface 120. The projection of the transparent protective member 220 completely covers the touch control 230, that is, the projection surface of the transparent protective member 220 onto the back surface 120 completely covers the projection surface of the touch control 230 onto the back surface 120. The projection of the touch control 230 completely covers the display member 210, that is, the projection surface of the touch control 230 onto the back surface 120 completely covers the projection surface of the display member 210 onto the back surface 120. The rough surface 1412 is the surface of the frame body 141 near the front 110 (i.e., away from the back panel 300). The rough surface 1412 is made by laser engraving, and the adhesive structure 240 is glued to the rough surface 1412 of the frame body 141. It is understood that the rough surface 1412 can also be made by etching, sandblasting, or surface coating. In other embodiments, the touch control 230 can also be directly mounted on the rough surface 1412 of the frame body 141.

[0074] The rough surface 1412 is used in conjunction with the adhesive structure 240, which can improve the adhesion of the adhesive structure 240 through a larger contact area, thereby further enhancing the connection between the touch control 230 and the frame body 141, and thus ensuring the stability of the touch control 230 installed on the frame body 141.

[0075] Reference Figure 2 and Figure 7 In one embodiment, the display module 200 further includes a touch control 230, which is located between the display element 210 and the transparent protective element 220 and is disposed on the frame body 141; the surface of the touch control 230 away from the transparent protective element 220 is coated with a primer layer 250.

[0076] In this embodiment, the touch control 230 is a capacitive touch film. The touch control 230 is adhesively attached to the side of the transparent protective member 220 near the back surface 120, and the display member 210 is adhesively attached to the side of the touch control 230 near the back surface 120. The projection of the transparent protective member 220 completely covers the touch control 230, that is, the projection surface of the transparent protective member 220 onto the back surface 120 completely covers the projection surface of the touch control 230 onto the back surface 120. Similarly, the projection of the touch control 230 completely covers the display member 210, that is, the projection surface of the touch control 230 onto the back surface 120 completely covers the projection surface of the display member 210 onto the back surface 120. It can be understood that the primer layer 250 may be applied only to the surface of the frame body 141 where the touch control 230 is mounted, or it may be applied to both the surface of the frame body 141 where the touch control 230 is mounted and the surface of the touch control 230 away from the transparent protective member 220. In addition, the surface of the touch control 230 away from the transparent protective element 220 may be coated with an adhesion promoter layer, a nano-level tack-enhancing coating, a moisture-proof isolation coating, or the surface of the touch control 230 away from the transparent protective element 220 may be processed using a surface treatment process.

[0077] The primer layer 250 not only enhances the bonding reliability between the touch control 230 and the component to be mated, but also improves the adaptability of the touch control 230 surface and reduces assembly difficulty.

[0078] In one specific embodiment, the frame body 141 is used to set the surface of the touch control 230 (i.e. the surface near the front 110) to be rough surface 1412, the surface of the touch control 230 away from the transparent protective member 220 is coated with a primer layer 250, and an adhesive structure 240 is provided between the rough surface 1412 of the frame body 141 and the primer layer 250 of the touch control 230.

[0079] Reference Figure 2 In one embodiment, the reflector 420 projects onto and covers the display element 210. In this embodiment, the reflector 420 projects onto and completely covers the display element 210, that is, the projection surface of the reflector 420 onto the back surface 120 completely covers the projection surface of the display element 210 onto the back surface 120.

[0080] The above structural design enables the light reflected by the reflector 420 to completely cover the effective display area of ​​the display 210, thereby improving the display effect of the display 210 and enhancing the user's visual comfort and image clarity.

[0081] Reference Figures 2 to 4 as well as Figure 7In one embodiment, the frame 140 further includes a clamping structure 143, which is disposed on the inner side 1411 and protrudes toward the center of the outer frame 100, and is located on the side of the support structure 142 near the front face 110; a sealing structure 260 is clamped and fixed between the clamping structure 143 and the display module 200.

[0082] In this embodiment, the clamping structure 143 and the frame body 141 are integrally molded. The sealing structure 260 is a sealing foam, and the sealing structure 260 is located on the side of the touch control 230 of the display module 200 away from the front 110; specifically, the surface of the sealing foam near the clamping structure 143 is in contact with the surface of the clamping structure 143 away from the back plate 300, and the surface of the sealing foam near the display module 200 is in contact with the surface of the touch control 230 near the back 120.

[0083] The clamping structure 143 and sealing foam used in conjunction not only fill the gap between the clamping structure 143 and the display module 200, effectively preventing external dust, moisture, oil, and other contaminants from entering the receiving space 130 through the gap, thus improving the sealing performance of the display device, but also, by compressing the sealing structure 260, the clamping structure 143 can form a uniform and continuous clamping force on the display module 200. Combined with the elastic reaction force of the sealing structure 260 itself, it can firmly restrict the display module 200 to a preset position on the frame body 141, thereby enhancing the stability of the display module 200 mounted on the frame body 141.

[0084] Reference Figures 2 to 4 as well as Figure 7 In one embodiment, the clamping structure 143 has a blocking structure 144 protruding toward the front 110 on the surface near the front 110, and the sealing structure 260 is located between the inner side 1411 and the blocking structure 144.

[0085] In this embodiment, the blocking structure 144 is a blocking protrusion, and the blocking structure 144 and the clamping structure 143 are integrally formed. It can be understood that the blocking structure 144 can also be fixedly installed on the clamping structure 143 by means of a snap-fit ​​structure, plug-in structure, screw structure, magnetic structure or welding structure.

[0086] The designed barrier protrusions can limit the sealing structure 260, effectively preventing the sealing structure 260 from detaching from the clamping structure 143, thereby ensuring that the sealing structure 260 is always clamped and fixed in a stable state, providing a guarantee for subsequent reliable sealing.

[0087] Reference Figure 2 In one embodiment, the display module 200 and / or the backlight module 400 are embedded in the receiving space 130.

[0088] In this embodiment, both the display module 200 and the backlight module 400 are fully embedded within the receiving space 130. In this case, the display module 200 is disposed on the front side 110, meaning that the display module 200 is correspondingly disposed on the front side 110; the back panel 300 is disposed on the back side 120, meaning that the back panel 300 is correspondingly disposed on the back side 120. It can be understood that only one of the display module 200 or the backlight module 400 is embedded within the receiving space 130, while the other is not embedded within the receiving space 130.

[0089] Both the display module 200 and the backlight module 400 are embedded in the accommodating space 130, which not only contributes to the overall thickness of the display device, but also allows the outer frame 100 to fully enclose the display module 200 and the backlight module 400, thereby extending the service life of the display module 200 and the backlight module 400.

[0090] In summary, the display device provided in this embodiment has at least the following beneficial technical effects: The display device of this application only requires the cooperation of the outer frame 100 and the flat back plate 300 to complete the stable installation of the display module 200 and the backlight module 400, without the need for a front frame and a middle frame. This structural design reduces the number of parts in the display device, simplifies the overall structure of the display device, reduces assembly difficulty and cost, and improves assembly efficiency. At the same time, the flat back plate 300 avoids the need for the back plate 300 to be molded into a cavity structure, saving mold costs, reducing processing difficulty, and shortening the processing cycle.

[0091] Meanwhile, the outer frame 100 is an extruded part. This structural design not only allows for the design of molding dies with different structures according to market demands, enabling the rapid production of outer frames 100 of different shapes and sizes, but also meets the design requirements of different display devices. This enhances the adaptability and designability of display devices, shortens processing cycles, and reduces design costs. It also helps improve the production efficiency of the outer frame 100. Furthermore, by using extrusion molding to manufacture the outer frame 100, the dimensional and shape accuracy of the outer frame 100 can be guaranteed, thereby improving the overall quality of the display device. In addition, compared with processes such as stamping, extrusion molding results in less material waste, effectively improving material utilization and reducing production costs.

[0092] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. It should be noted that, for those skilled in the art, several equivalent obvious modifications and / or equivalent substitutions can be made without departing from the technical principles of this application, and these obvious modifications and / or equivalent substitutions should also be considered within the scope of protection of this application.
