Description

Display device Technical Field

[0001] This application relates to the field of display technology, and more specifically to a display device. Background Technology

[0002] With the development of the display industry, narrow bezel design has become an important research direction. Narrow bezel display devices bring users a stunning visual effect and an excellent visual experience. However, their narrower module bezels limit the fixation and protection of the display panel, making it more prone to edge breakage, panel detachment, and other problems. In addition, the material and processing costs are relatively high.

[0003] Current narrow-bezel technologies for large-size displays typically employ side-sealing techniques to increase buffer protection and reduce micro-cracks, thereby lowering the risk of screen breakage. This often involves eliminating the side bezels while retaining a wider bottom bezel to protect against impacts. However, even with the side bezels removed, the bottom bezel remains substantial, leaving the sides and top of the glass almost exposed, offering little protection. Therefore, providing a display device that effectively protects the display panel while achieving the visual effect of a narrow bezel is a crucial technical challenge. Summary of the Invention

[0004] This application provides a display device that can effectively protect the display panel and achieve a narrow bezel visual effect.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0040] Please refer to Figure 1. This application provides a display device 1000. The display device 1000 can be applied to, but is not limited to, monitors, televisions, electronic paper panels, wireless devices, personal data assistants (PDAs), handheld or portable computers, GPS receivers / navigators, cameras, MP4 video players, camcorders, game consoles, watches, television monitors, flat panel display devices 1000, computer monitors, automotive display devices 1000 (e.g., odometer display devices 1000, etc.), navigators, cockpit controllers and / or display devices 1000, camera view display devices 1000 (e.g., display devices 1000 for rearview cameras in vehicles), electronic photographs, electronic billboards or signs, and other devices with display functions.

[0041] This application provides a display device 1000 that can effectively protect the display panel and achieve a narrow bezel visual effect. The display device 1000 includes, but is not limited to, one of a liquid crystal display (LCD), an organic electroluminescence display (OLED), or a micro-LED display.

[0042] Please refer to Figure 1. The display device 1000 includes at least a display panel 100, a backlight module 200, a side frame 300, and an adhesive 400.

[0043] Optionally, referring to Figure 2, the display panel 100 includes a color filter substrate 110, a TFT array substrate 120, and a liquid crystal layer 130. After the color filter substrate 110 and the TFT array substrate 120 are assembled, the periphery of the color filter substrate 110 and the TFT array substrate 120 are sealed with an adhesive layer. Liquid crystal molecules are sealed in the gap between the color filter substrate 110 and the TFT array substrate 120 to form the liquid crystal layer 130.

[0044] Referring to Figure 1, the display panel 100 includes a top surface 101, a bottom surface 102 disposed opposite to each other, and a side surface connecting the top surface 101 and the bottom surface 102. Optionally, the color filter substrate 110 is located above the TFT array substrate 120.

[0045] The top surface 101 of the display panel 100 is the surface of the color filter substrate 110 that faces away from the TFT array substrate 120.

[0046] The backlight module 200 is fixedly connected to the bottom surface 102 of the display panel 100, and the backlight module 200 and the display panel 100 are fixed as a whole in the thickness direction.

[0047] Please refer to Figure 1. The side frame 300 includes a front panel 310, a side panel 320, and a rear panel 330 connected in sequence. The cross-section of the side frame 300 is approximately C-shaped.

[0048] Please refer to Figure 1. The front panel 310 is attached to the top surface 101 of the display panel 100.

[0049] Optionally, referring to Figure 1, the display panel 100 includes, but is not limited to, a first protective film 140, a color filter substrate 110, a TFT array substrate 120, and a second protective film 150 arranged sequentially. The first protective film 140 may also be an upper polarizer. The second protective film 150 may also be a lower polarizer or a lower protective foam.

[0050] Referring to Figure 1, the first protective film 140 is designed to be recessed relative to the color filter substrate 110 at the narrow bezel, with a recess width ≥ 1 mm. This exposes a bonding area on the side of the color filter substrate 110 facing away from the TFT array substrate 120, facilitating the bonding of the front panel 310 to the bonding area on the top surface 101 of the display panel 100. The bonding area between the front panel 310 and the display panel 100 is a surface-to-surface bonding, with a surface-to-surface bonding width ≥ 1 mm. Therefore, the assembly of the front panel 310 of the side frame 300 and the display panel 100 has good stability.

[0051] Please refer to Figure 1, where the side panel 320 is opposite to the side of the display panel 100.

[0052] Specifically, one side of the backlight module 200 is flush with or nearly flush with one side of the display panel 100. The side plate 320 is opposite to the side of the backlight module 200 and the side of the display panel 100 and has a small gap.

[0053] Please refer to Figure 1. The rear plate 330 is fixedly connected to the backlight module 200 on the side opposite to the display panel 100. The rear plate 330 is located on the side of the backlight module 200 opposite to the display panel 100, and the fixing method between the rear plate 330 and the backlight module 200 includes, but is not limited to, snap-fit ​​connection, press-fit, screw connection, etc.

[0054] Please refer to Figure 1. The adhesive component 400 is disposed in the gap between the side frame 300 and the side of the backlight module 200 and the side of the display panel 100. It is bonded between the side plate 320 and the side of the display panel 100. The side frame 300 is fixed to the backlight module 200 and the display panel 100 as a whole by means of the adhesive component 400.

[0055] Specifically, referring to Figure 1, one side of the adhesive component 400 is adhered to the side plate 320, and the other end of the adhesive component 400 is adhered to the side of the backlight module 200 and the side of the display panel 100. Thus, the side frame 300 and the adhesive component 400 are assembled without gaps, and the adhesive component 400 is assembled without gaps to the side of the display panel 100 and the backlight module 200. Therefore, the side frame 300 is assembled without gaps to the side of the display panel 100 and the backlight module 200, achieving a narrow bezel design for the display device 1000. The narrow bezel width mentioned in this application refers to the distance between the boundary of the display area of ​​the display panel 100 and the outer side of the side frame 300.

[0056] During assembly, the display panel 100 is first fixed along the thickness direction, and the side frame 300 is pressed and fixed to at least one of the top, left, and right sides of the display panel 100 and the backlight module 200 by the adhesive 400, so as to fix the display panel 100, the backlight module 200 and the side frame 300 together.

[0057] Compared to conventional technologies, where the display panel 100 has no side frame 300 and the sides are sealed with adhesive, the glass periphery of the display panel 100 is exposed, posing a risk of collision damage and having weak impact resistance.

[0058] The display device 1000 provided in this application is designed with a display panel 100 including a top surface 101 and a bottom surface 102 disposed opposite to each other, and a side surface connected between the top surface 101 and the bottom surface 102; a backlight module 200 is fixedly connected to the bottom surface 102 of the display panel 100; a side frame 300 includes a front plate 310, a side plate 320 and a rear plate 330 connected in sequence, the front plate 310 is attached to the top surface 101 of the display panel 100, the side plate 320 is opposite to the side surface of the display panel 100, and the rear plate 330 is fixedly connected to the side of the backlight module 200 away from the display panel 100; and an adhesive 400 is bonded between the side plate 320 and the side surface of the display panel 100. By providing a side frame 300 on the side of the display panel 100 and the backlight module 200, and fixing it to the side of the display panel 100 and the backlight module 200, the glass side of the display panel 100 is protected. At the same time, the side plate 320 of the side frame 300 is bonded to the side of the display panel 100 by an adhesive 400, so as to achieve a gapless assembly between the side frame 300 and the display panel 100. This reduces the bezel width of the display device 1000, while also providing better protection for the side of the product. In addition, the material cost is low and the assembly process is simple.

[0059] Optionally, referring to Figure 1, the adhesive 400 is a compressible adhesive. The adhesive 400 is in a compressed state between the side plate 320 and the side surface of the display panel 100. For example, the thickness of the adhesive 400 in its uncompressed state is h1, and one side of the adhesive 400 is bonded to the side plate 320. When the side frame 300 is installed on the display panel 100 and the backlight module 200, the other side of the adhesive 400 is bonded to the side surface of the display panel 100 and / or the backlight module 200. During installation, the side frame 300 compresses the adhesive 400, making the thickness of the adhesive 400 h2, where h2 is less than h1; for example, h1 is 4 mm and h2 is 1 mm.

[0060] By setting the adhesive 400 as a compressible adhesive, and the adhesive 400 being compressed between the side plate 320 and the side of the display panel 100, the side frame 300 compresses the adhesive 400 during installation. This not only allows the two sides of the adhesive 400 to be bonded between the side plate 320 and the side of the display panel 100 respectively, achieving gapless assembly, but also compresses the thickness of the adhesive 400 to a minimum, thereby reducing the gap between the side plate 320 and the side of the display panel 100, and further reducing the bezel width.

[0061] For example, adhesive component 400 may be double-sided foam adhesive, double-sided tape, paste sealant, rubber tape, silicone tape, etc.

[0062] Please refer to Figure 3. Adhesive component 400 is foam adhesive 410.

[0063] Optionally, the side frame 300 may include, but is not limited to, injection-molded frames, metal frames, etc. The side frame 300 has a certain degree of extensibility, allowing it to deform during assembly. Under external force, the distance between the front panel 310 and the rear panel 330 increases, placing the display panel 100 and the backlight module 200 in the space between the front panel 310 and the rear panel 330. Pushing the side panel 320 towards the side where the display panel 100 is located causes the adhesive 400 on the side panel 320 to adhere to the side of the display panel 100 and be compressed to a smaller thickness. At this point, the side frame 300 is in a suitable position. After the external force is removed, the deformation of the side frame 300 returns to normal, clamping the front panel 310 and the rear panel 330 against the edges of the display panel 100 and the backlight module 200.

[0064] Please refer to Figure 4. The adhesive 400 is an elastic colloid. The elastic colloid is a buffer adhesive 420. The buffer adhesive 420 can create a gap between the side plate 320 and the side edge of the display panel 100, and can also elastically protect the side glass, improve the impact resistance of the display panel 100, and prevent the side frame 300 from puncturing the first protective film 140. The material of the buffer adhesive 420 includes, but is not limited to, at least one of UV adhesive, hot melt adhesive, epoxy adhesive, etc. Optionally, when the adhesive 400 is an elastic colloid and is provided on the side plate 320, it can be in a semi-cured state. During the installation of the side plate 320 on the display panel 100 and the backlight module 200, the elastic colloid is slightly compressed by squeezing, so that the elastic colloid is bonded to the side of the side plate 320 and the side of the display panel 100. That is, the bottom of the elastic colloid is fixedly connected to the side of the side plate 320 facing the side, and the top of the elastic colloid abuts against the side of the display panel 100.

[0065] Optionally, referring to Figure 5, the area between the side plate 320 and the sides of the display panel 100 and the backlight module 200, excluding the adhesive 400, includes a gap 600 to be filled. Further, the area between the side plate 320 and the sides of the display panel 100 and the backlight module 200, excluding the adhesive 400, is the gap 600 to be filled.

[0066] Referring to Figure 5, the display device 1000 also includes a filler adhesive 500. The filler adhesive 500 is disposed in all or part of the gaps 600 to be filled. The filler adhesive 500 is disposed in the gaps 600 to be filled in the manner including, but not limited to, applying adhesive before the side frame 300 is installed and applying adhesive by dispensing / injection after the side frame 300 is installed.

[0067] Optionally, referring to Figure 5, the adhesive 400 is foam adhesive 410. One side of the foam adhesive 410 is adhered to the side panel 320. A paste-like adhesive is applied to other areas of the side panel 320 of the side frame 300 where the foam adhesive 410 is not applied. The side frame 300 is installed on the edge of the display panel 100 and the backlight module 200, and the foam adhesive 410 is squeezed to adhere to the side of the display panel 100. The filler adhesive 500 fills the gap 600 to be filled. The filler adhesive 500 can be cured by heat or air drying. After curing, the filler adhesive 500 can fix the front panel 310, side panel 320, bottom plate, side of display panel 100, and side of backlight module 200 together.

[0068] Optionally, referring to Figure 6, the adhesive 400 is a buffer adhesive 420. Semi-cured or cured buffer adhesive 420 is applied to the side plate 320. A paste-like adhesive is applied to other areas of the side plate 320 of the side frame 300 where buffer adhesive 420 is not applied. The side frame 300 is then installed on the edges of the display panel 100 and the backlight module 200, and the buffer adhesive 420 is pressed to bond to the side of the display panel 100. Filler adhesive 500 fills the gap 600 to be filled. The filler adhesive 500 can be cured by heat or air drying. After curing, the filler adhesive 500 can fix the front panel 310, side plate 320, bottom plate, side of the display panel 100, and side of the backlight module 200 together while maintaining a small gap between the side plate 320 and the side of the display panel 100.

[0069] Optionally, referring to Figures 7 and 8, the adhesive 400 divides the gap 600 to be filled into a first gap 610 and a second gap 620. The first gap 610 is located between the adhesive 400 and the side of the front panel 310 and the display panel 100. The second gap 620 is located between the adhesive 400 and the rear panel 330. At least a portion of the filler adhesive 500 is disposed in the first gap 610, and at least a portion of the filler adhesive 500 is disposed in the second gap 620. In other words, a portion of the filler adhesive 500 is fixedly bonded between the front panel 310, the side panel 320, the upper side of the adhesive component 400, and the side of the display panel 100, while the other portion of the filler adhesive 500 is fixedly bonded between the rear panel 330, the side panel 320, the lower side of the adhesive component 400, and the side of the backlight module 200. This can increase the bonding area between the side frame 300 and the display panel 100 and the backlight module 200, improve bonding stability, and also reduce the gaps within the side frame 300.

[0070] Optionally, referring to Figures 9 to 11, the adhesive 400 has a plurality of conductive gaps 630. The conductive gaps 630 connect the first gap 610 and the second gap 620. At least a portion of the filler adhesive 500 is disposed in the conductive gaps 630. If the adhesive 400 is disposed along the extending direction of the side plate 320, and the adhesive 400 is also bonded between the side plate 320 and the side of the display panel 100, there may be a situation where the gaps on the upper and lower sides of the adhesive 400 are not conductive, which may prevent the filler adhesive 500 from moving sufficiently in the gap 600 to be filled (for example, it may not be able to move from the first gap 610 to the second gap 620), thus resulting in the gap 600 not being filled completely.

[0071] In this embodiment, by setting multiple conductive gaps 630 connecting the first gap 610 and the second gap 620, even when the adhesive 400 is bonded between the side plate 320 and the side of the display panel 100, the gaps on the upper and lower sides of the adhesive 400 are still connected, and the filler adhesive 500 can move fully in the gap to be filled 600 (for example, it can move from the first gap 610 through the conductive gap 630 to the second gap 620), thereby enabling the filler adhesive 500 to fill the gap to be filled 600.

[0072] Optionally, referring to Figure 9, the number of adhesive components 400 is one. Multiple conductive gaps 630 all penetrate the adhesive component 400. For example, the adhesive component 400 is a strip-shaped foam adhesive 410, which is disposed along the side plate 320. Multiple conductive gaps 630 penetrate the upper and lower sides of the strip-shaped foam adhesive 410, so that the first gap 610 on the upper and lower sides of the strip-shaped foam adhesive 410 communicates with the second gap 620. During the process of applying paste-like adhesive or dispensing adhesive to other locations on the side plate 320 of the side frame 300 where foam adhesive 410 is not provided, the filler adhesive 500 can fill the first gap 610, the conductive gap 630 and the second gap 620 under extrusion pressure, thereby filling the entire gap to be filled 600, so as to improve the connection strength between the side frame 300 and the display panel 100 and the backlight module 200. By providing the filler adhesive 500 on the periphery of the display panel 100, the filler adhesive 500 can absorb external impact force and improve the impact resistance of the display device 1000.

[0073] Optionally, referring to Figure 10, the number of adhesive members 400 is one. The adhesive member 400 has multiple recesses at one end facing the side of the display panel 100. These recesses form the conductive gaps 630. For example, the adhesive member 400 is a strip-shaped buffer adhesive 420, which is disposed along the side plate 320. The strip-shaped buffer adhesive 420 has multiple recesses at one end facing the side of the display panel 100. Protrusions are formed between adjacent recesses. When the end of the strip-shaped buffer adhesive 420 facing the side of the display panel 100 abuts against the side of the display panel 100, each recess forms a conductive gap 630, connecting the first gap 610 and the second gap 620 on the upper and lower sides of the strip-shaped buffer adhesive 420. During the process of applying paste-like adhesive or dispensing adhesive to other locations on the side plate 320 of the side frame 300 where no strip-shaped buffer adhesive 420 is provided, the filler adhesive 500 can fill the first gap 610, the conductive gap 630 and the second gap 620 under extrusion pressure, thereby filling the entire gap to be filled 600, so as to improve the connection strength between the side frame 300 and the display panel 100 and the backlight module 200. By providing the filler adhesive 500 on the periphery of the display panel 100, the filler adhesive 500 can absorb external impact force and improve the impact resistance of the display device 1000.

[0074] Hot melt adhesive is applied to the side frame 300, and the side frame 300, backlight module 200 and display panel 100 are stably fixed together by the adhesive effect of the hot melt adhesive, which helps to meet the requirements of narrow bezel and improve the robustness of display device 1000.

[0075] Optionally, referring to Figure 11, the number of adhesive components 400 is multiple. The multiple adhesive components 400 are arranged along the extending direction of the side plate 320. The gap between two adjacent adhesive components 400 is the conductive gap 630. For example, the adhesive component 400 is foam adhesive 410, and multiple foam adhesives 410 are arranged along the extending direction of the side plate 320. The gap between two adjacent foam adhesives 410 is the conductive gap 630. This connects the first gap 610 on the upper and lower sides of the foam adhesive 410 with the second gap 620. During the process of applying paste-like adhesive or dispensing adhesive to other locations on the side plate 320 of the side frame 300 where foam adhesive 410 is not provided, the filler adhesive 500 can fill the first gap 610, the conductive gap 630 and the second gap 620 under extrusion pressure, thereby filling the entire gap to be filled 600, so as to improve the connection strength between the side frame 300 and the display panel 100 and the backlight module 200. By providing the filler adhesive 500 on the periphery of the display panel 100, the filler adhesive 500 can absorb external impact force and improve the impact resistance of the display device 1000.

[0076] Optionally, referring to Figures 12 and 13, the side frame 300 has at least one opening 700. The opening 700 communicates with the gap 600 to be filled. The opening 700 is used to fill the gap 600 with glue. The opening 700 is provided on the side plate 320 or the rear plate 330.

[0077] Specifically, after the side frame 300 is installed on the display panel 100 and the backlight module 200, glue can be filled into the gap 600 through the opening 700 to fill the gap 600. After the glue cures into filler glue 500, the fixing strength between the display panel 100, the backlight module 200 and the side frame 300 is improved. By providing filler glue 500 on the periphery of the display panel 100, filler glue 500 can absorb external impact force and improve the impact resistance of the display device 1000.

[0078] Optionally, as shown in Figure 1, the display device 1000 also includes sealant 800.

[0079] Referring to Figure 14, the backlight module 200 includes a back plate 210 and an optical component 220. The back plate 210 has a recessed center forming an accommodating space. The optical component 220 is housed within this accommodating space. The four edges of the back plate 210 are fixedly connected to the back of the display panel 100 using a sealant 800. Optionally, the sealant 800 also has a light-shielding function to prevent light leakage from the optical component 220. The sealant 800 includes, but is not limited to, light-shielding double-sided tape, light-shielding foam layers, etc.

[0080] Furthermore, sealant 800 can also prevent filler adhesive from entering the accommodating space.

[0081] Referring to Figure 14, the optical component 220 includes, but is not limited to, a reflector 221, a light guide plate 222, and an optical film 223 arranged sequentially from the back plate 210 to the display panel 100. Further, the optical film 223 includes, but is not limited to, a diffusion film 224, a first brightness enhancement film 225, and a second brightness enhancement film 226 arranged sequentially from the back plate 210 to the display panel 100. The backlight module 200 also includes a backlight source 230. The light emitted from the backlight source 230 is reflected, scattered, and diffused by the optical component 220 before being emitted to provide light to the display panel 100, enabling the display panel 100 to perform its display function.

[0082] Optionally, referring to Figures 1, 13, and 15, the rear plate 330 has at least one protrusion 331 protruding towards the front plate 310. The backlight module 200 has at least one groove 240 on the side opposite to the display panel 100. The protrusion 331 is engaged with the side wall of the groove 240. The rear plate 330 of the side frame 300 is engaged with the back plate 210 of the backlight module 200.

[0083] Optionally, side frames 300 are respectively located on the upper, left, and right sides of the back panel 210. In other words, the upper, left, and right sides of the back panel 210 are respectively connected to the back panel 330 via hooks. The side frames 300 on the upper, left, and right sides of the back panel 210 can be interconnected as a whole or set independently. Optionally, the side frames 300 are formed by injection molding, and the corners of the side frames 300 are closed. The back panel 210 is formed by stamping sheet metal, so the corners of the back panel 210 have process notches. After the side frames 300 are attached to the back panel 210, the side frames 300 can cover the notches at the corners of the back panel 210 to prevent light leakage. Of course, in other embodiments, the back panel 210 can also be formed by injection molding.

[0084] A circuit board is provided on the lower side of the backplate 210, which is electrically connected to the lower end of the TFT array substrate 120 through a flip-chip film.

[0085] This application proposes a low-cost, narrow-bezel display device 1000. The display panel 100 and backlight module 200 are fixed and protected by a side frame 300. The side frame 300 originates from the top surface 101 of the display glass and is fixed to the back plate 210, forming a complete C-shaped protection for the sides of the display panel 100. In this application, the inner wall of the side frame 300 is fitted with cushioning foam adhesive 410, elastic cushioning adhesive 420, or by injection molding, which can replace the sealing of the glass sides. The elastic assembly of the injection-molded side frame 300 reduces the gap between the side frame 300 and the side of the display glass, thereby effectively reducing the screen bezel width and having a relatively low risk of peeling, detachment, and edge screen breakage.

[0086] Meanwhile, this application uses an injection-molded frame as the edge-sealing side frame 300, replacing the glass side sealing with the edge-sealing side frame 300, and the side frame 300 is fixed to the back plate 210 of the backlight module 200 by a snap fastener, so that this application has a narrow bezel function while being relatively inexpensive and controllable in cost.

[0087] The display panel 100 includes one of an upper protective film or an upper polarizing plate, and also includes upper and lower display panels 100, and one of a lower protective film, a lower polarizing plate or a lower protective foam.

[0088] The upper protective film or upper polarizing plate has an inward-sloping design at the narrow bezel, with an inward width of ≥1mm, to facilitate the formation of a tight-fitting area for the top plate. The injection-molded side frame 300 is made of, but is not limited to, conventional plastic materials such as black or gray PP, PC, PET, or mixtures thereof. The adhesive component 400 includes foam adhesive 410, which serves as a buffer and fixation; the sealant 800 is double-sided adhesive or double-sided foam adhesive 410; the back plate 210 is made of metal, and the metal back plate 210 needs to be perforated at the corresponding position on the side frame 300 to form a groove 240 for assembly of the side frame 300.

[0089] During assembly, the display panel 100 and the back panel 210 are first pre-fixed using sealant 800; simultaneously, adhesive 400 is pre-fixed to the side frame 300, with the position of adhesive 400 corresponding to the side of the display panel 100, providing side support and protection for the side of the display panel 100. Finally, the pre-assembled injection-molded side frame 300 is assembled with the pre-assembled display panel 100 and back panel 210 to form a complete display device 1000; the injection-molded side frame 300 starts from the recessed part of the upper surface of the display glass and is fixed to the back panel 210, forming a complete C-shaped protection for the side of the display panel 100.

[0090] The display device 1000 provided in this embodiment replaces the side sealant of conventional display glass with an adhesive component 400. Since the injection-molded side frame 300 and the adhesive component 400 (e.g., foam) have a certain deformation capability, the gap between the adhesive component 400 (e.g., foam) and the display panel 100 is squeezed, achieving 0mm gap assembly. This reduces the width of the display device 1000's bezel while also providing better protection for the product's sides. Furthermore, the material cost is low and the assembly process is simple.

[0091] The adhesive 400 can be a buffer adhesive 420, which includes, but is not limited to, black or gray UV adhesive, hot melt adhesive, epoxy adhesive, etc. When the adhesive 400 and the side frame 300 are pre-assembled, they are injection molded and require appropriate curing treatment; and the side frame 300 has openings 700 in the side panel 320 or the rear panel 330. When assembling the side frame 300 after adhesive injection to the display panel 100 and the backlight module 200, adhesive can be applied at the openings 700 to further strengthen the connection between the side frame 300 and the display device 1000, preventing peeling, detachment, and edge screen breakage. Specifically, the color of the filler adhesive 500 can be close to that of the side frame 300 to prevent aesthetic defects.

[0092] Furthermore, decorative strips or adhesive strips of the same color as the side frame 300 can be applied to the area where the opening 700 is located to avoid unsightly appearance issues.

[0093] This embodiment uses buffer adhesive 420 instead of conventional side sealing adhesive for display glass. Since the injection-molded side frame 300 and the adhesive component 400 (e.g., foam) have a certain degree of deformation capability, they compress the gap between the adhesive component 400 (e.g., foam) and the display panel 100, achieving a 0mm gap assembly. This reduces the bezel width of the display device 1000 while also providing better protection for the product's sides. Furthermore, the material cost is lower, and the assembly process is simpler. This embodiment also uses secondary adhesive application for better fixation, reducing the risk of the display panel 100 detaching and edge screen breakage, while still maintaining a good cost advantage.

[0094] The above are some embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
