[0002] With the development of display technology, display devices have become mainstream in various consumer electronics products such as mobile phones, televisions, personal digital assistants, digital cameras, laptops, and desktop computers due to their advantages such as high image quality, energy saving, thin body, and wide application range. In recent years, the display device industry has seen continuous development, with a trend towards narrower bezels. For example, narrow-bezel TVs narrow the non-display area at the edge of the display panel, and the bezel adopts a simpler and more refined design, making the product more aesthetically pleasing. Currently, the concept of borderless display panels has also emerged in the industry, which removes the outer frame that obstructs the non-display area of ​​the display panel, achieving a borderless feature.

[0072] The embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions of the embodiments of this application.

[0073] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in the specification of this application means the presence of the stated features, integers, steps, operations, elements, and / or components, but does not exclude other features, information, data, steps, operations, elements, components, and / or combinations thereof supported by the art. The term “and / or” as used herein refers to at least one of the items defined by the term; for example, “A and / or B” can be implemented as “A,” or as “B,” or as “A and B.”

[0074] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0075] The research and development concept of this application includes: Currently, the industry has seen the emergence of the concept of borderless display devices, which involves removing the outer frame that obscures the non-display area of ​​the display panel to achieve a borderless feature. Related display devices, such as... Figure 13 As shown, the device includes a display panel 71, a glass diffuser 72, an aluminum extrusion structure 73, and a back panel. The glass diffuser 72 is disposed on the light-incident side of the display panel 71. The aluminum extrusion structure 73 includes a support portion disposed between the glass diffuser and the back panel, and an outer portion disposed on the outside of the back panel and the display panel. The support portion and the outer portion are an integrated structure, meaning that the aluminum extrusion structure 73 both supports the glass diffuser 72 and the display panel 71 and serves as the outer frame of the display device. Because the outer portion of the aluminum extrusion structure 73 needs to achieve a frameless effect, a certain gap needs to exist between the outer portion of the aluminum extrusion structure 73 and the edges of the display panel 71 and the glass diffuser 72. To prevent damage to the edges of the display panel 71 and the glass diffuser 72, a sealing adhesive 75 needs to be applied to the edges of the display panel 71 and the glass diffuser 72.

[0076] However, in the related display devices, since the glass diffuser plate 72 and the display panel 71 are both glued together, and the outer part of the aluminum extrusion structure 73 is located around the glass diffuser plate 72 and the display panel 71, when the display device has a production defect, because the outer part of the aluminum extrusion structure 73 blocks the display panel 71 and the glass diffuser plate 72 around, the cutter cannot reach in to cut the glue 74 that bonds the display panel 71 and the glass diffuser plate 72, making it difficult to repair the display panel 71 and the glass diffuser plate 72. Even if the display panel 71 and the glass diffuser plate 72 are disassembled, they are easily damaged.

[0077] In the fabrication of the display device, the glass diffuser plate 72 is first bonded to the supporting portion of the aluminum extrusion structure 73 using adhesive 74. Then, the display panel 71 is bonded to the glass diffuser plate 72 using adhesive 74. During this process, the bonding of the glass diffuser plate 72 to the supporting portion of the aluminum extrusion structure 73 with adhesive 74 requires several hours to ensure that the adhesive 74 is basically cured. Only then can the display panel 71 be bonded to the glass diffuser plate 72 using adhesive 74. This process also requires several hours to proceed to the next step. Therefore, the production cycle is long, and the production process increases labor costs such as handling.

[0078] Because there is a certain gap between the outer part of the aluminum extrusion structure 73 and the edges of the display panel 71 and the glass diffuser plate 72, and the black matrix structure between the array substrate and the color filter substrate of the display panel 71 is relatively narrow, light leakage will occur at the edge of the polarizer. Under external viewing angle, the light leaking out from the edge of the polarizer can be seen.

[0079] The technical solution of this application and how it solves the above-mentioned technical problems are described in detail below with specific embodiments. It should be noted that the following embodiments can be referenced, borrowed, or combined with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0080] It should be noted that in the diagram, AA represents the display area of ​​the display panel, and BB represents the non-display area of ​​the display panel.

[0081] This application provides a display device 100, the structural schematic diagram of which is shown below. Figures 1 to 12 As shown, it includes: display component 1, middle frame component 2, border component 3, adhesive structure 4, and back panel 5.

[0082] The mid-frame assembly 2 is located on the light-incident side of the display assembly 1; at the edge of the display assembly 1, the mid-frame assembly 2 provides support for the display assembly 1 in the thickness direction of the display assembly 1, and the mid-frame assembly 2 is connected to the display assembly 1 in the thickness direction of the display assembly 1 by the adhesive structure 4; in the thickness direction of the display assembly 1, the distance between the mid-frame assembly 2 and the display assembly 1 is greater than 0.

[0083] The back panel 5 is located on the side of the middle frame assembly 2 away from the display assembly 1.

[0084] The frame component 3 is located around the display component 1 and around the middle frame component 2, and the frame component 3 and the middle frame component 2 are detachably connected.

[0085] In this embodiment, in the thickness direction of the display component 1, the distance from the middle frame component 2 to the display component 1 is greater than 0, indicating that the extension surface (e.g., plane) of the surface of the display component 1 near the middle frame component 2 does not overlap with the middle frame component 2.

[0086] Specifically, the middle frame assembly 2 is located on the light-incident side of the display assembly 1. In the thickness direction of the display assembly 1, the middle frame assembly 2 provides support for the display assembly 1, and the distance between the middle frame assembly 2 and the display assembly 1 is greater than 0. The middle frame assembly 2 is disposed on the side of the display assembly 1 near the back plate 5, and the display assembly 1 is connected to the middle frame assembly 2 in the thickness direction of the display assembly 1. Furthermore, the middle frame assembly 2 and the frame piece 3 are independent components. In the direction parallel to the display assembly 1, the middle frame assembly 2 and the frame piece 3 are detachably connected. Therefore, when reworking the display device 100, the frame piece 3 and the middle frame assembly 2 can be disassembled first. Then, tools such as cutting tools can cut the connection between the display assembly 1 and the middle frame assembly 2 in the direction parallel to the display assembly 1. This makes it easy to remove the display assembly 1, which includes the display panel 11 and the optical film 12, and facilitates the rework operation. Moreover, there is no need to contact the display assembly 1 before the above cutting, and there is no need to pry the side of the display panel 11 during the cutting process. This reduces the probability of damage to the display assembly 1 during the rework process, helps to protect the integrity of the display assembly 1, and improves the yield.

[0087] Optionally, the display device 100 further includes a light source assembly located between the back panel 5 and the display assembly 1. Light emitted from the light source assembly passes through the display assembly 1 and exits the display device 100. The mid-frame assembly 2 and the back panel 5 constitute a light propagation space 101. The mid-frame assembly 2 includes a support surface 21a, which is the area where the mid-frame assembly 2 contacts the adhesive structure 4, and the adhesive structure 4 is a transparent adhesive. The display assembly 1 includes a display panel 11 and an optical film 12 located on the light-incident side of the display panel 11. The orthographic projection of the support surface 21a onto the display panel 11 is located in the non-display area of ​​the display panel 11. The mid-frame assembly 2 also includes an exposed surface 23a facing the light propagation space 101 and not covered by the adhesive structure 4.

[0088] In this embodiment, the middle frame assembly 2 and the back plate 5 form a light propagation space 101. While supporting the display assembly 1, the middle frame assembly 2 can also block the light emitted by the light source assembly from being emitted outward. The exposed surface 23a of the middle frame assembly 2 can support the supporting surface 21a.

[0089] Optionally, such as Figure 2 and Figure 3 As shown, the mid-frame assembly 2 includes a support portion 21 and a fixing portion 22. The support surface 21a is located on the side of the support portion 21 closer to the display assembly 1. The fixing portion 22 is located on the side of the support portion 21 away from the display assembly 1. The back plate 5 includes a back plate body 51 extending in the same direction as the display assembly 1, and a back plate flange 52 extending from the edge of the back plate body 51 toward the display assembly 1. The back plate flange 52 is bent to form a platform portion 521 located between the back plate body 51 and the mid-frame assembly 2. The fixing portion 22 is abutted against the platform portion 521.

[0090] The light source assembly is a direct-lit backlight assembly, including a lamp panel 102, which is located on the side of the back panel body 51 near the display component 11; the light source assembly includes a reflector 103, which is located on the side of the lamp panel 102 near the display component 1; the reflector 103 includes a cutout area, through which the light emitted by the lamp panel 102 enters the light propagation space 101.

[0091] The middle frame assembly 2 also includes a limiting part 26, which is connected to the support part 21 and extends to a position close to the reflector 103 for limiting the reflector 103; a portion of the exposed surface 23a is located on the limiting part 26 and is located on the side of the limiting part 26 facing the light propagation space 101.

[0092] It should be noted that the light board 102 can be an LED light board 102. The orthographic projection of the LED chip on the light board 102 is at least partially located within the orthographic projection of the cutout area of ​​the reflector 103 on the light board 102.

[0093] In this embodiment, the fixing part 22 of the middle frame assembly 2 abuts against the platform part 521 of the back plate 5, which helps to enhance the connection strength between the middle frame assembly 2 and the back plate 5; the limiting part 26 of the middle frame assembly 2 can be used to limit the reflective sheet 103, which helps to limit the position of the reflective sheet 103, and further helps to improve the display performance of the display device 1000.

[0094] Optionally, the limiting part 26 includes an extension disposed along the side of the lamp panel 102 toward the display component 1, the extension extending along the plane of the lamp panel 102.

[0095] In this embodiment, the extension of the limiting portion 26 can limit the movement of the reflective sheet 103 in a direction perpendicular to the display panel, further limiting the position of the emitting sheet.

[0096] Optionally, continue to refer to Figure 2 and Figure 3 As shown, in the transition area between the support part 21 and the limiting part 26, the exposed surface 23a transitions smoothly; the back plate flange 52 is located between the limiting part 26 and the fixing part 22.

[0097] In this embodiment, the middle frame assembly 2, the frame piece 3, and the back panel flange 52 can be fixed simultaneously by bolts, which can help enhance the stability of the overall display device 100.

[0098] Optionally, such as Figure 1 , Figure 2 and Figure 4 As shown, at least a portion of the support surface 21a extends in the same direction as the display panel 11 in its support area.

[0099] In this embodiment, the support surface 21a extends along the extension direction of the display component 1, that is, the support surface 21a is a plane, and the thickness of the adhesive structure 4 is the same everywhere. Thus, the display component 1 and the middle frame component 2 are connected by a plane, which can help enhance the adhesion and reduce the difficulty of operation.

[0100] Optionally, such as Figure 3 , Figure 7 and Figure 8 As shown, the support surface 21a includes a first curved surface, which gradually approaches the outer contour of the display device 100 as it extends towards the display component 1 in the thickness direction.

[0101] In this embodiment, the first curved surface is a smoothly transitioned curved surface. As the first curved surface moves from the non-display area to the display area, it moves further and further away from the display component 1, and the thickness of the adhesive structure 4 becomes thicker and thicker. Moreover, since the adhesive structure 4 is a transparent adhesive, it can help reduce or eliminate the phenomenon of dark edges under a large viewing angle, which is beneficial to improving the display effect of the display component 1.

[0102] It should be noted that the adhesive structure 4 can be selected with an adhesive type that has good shape retention and does not overflow, which can help reduce the flow of the adhesive structure 4 on the first curved surface and prevent the adhesive structure 4 from flowing to the display area and affecting the display screen of the display component 1.

[0103] Optionally, such as Figure 7 and Figure 8As shown, the exposed surface 23a and the first curved surface are a continuous structure, and the exposed surface 23a and the first curved surface together form the second curved surface 24a. The first angle 24b between the tangent of the end of the second curved surface 24a near the back plate body 51 and the plane where the display panel is located is not less than 90 degrees and not more than 105 degrees; the second angle 24c between the tangent of the end of the second curved surface 24a away from the back plate body 51 and the plane where the display panel is located is not less than 27 degrees and not more than 33 degrees; wherein, both the first angle 24b and the second angle 24c are oriented towards the light propagation space 101.

[0104] In this embodiment, the end of the second curved surface 24a near the back plate body 51 and the end of the second curved surface 24a away from the back plate body 51 are smoothly transitioned.

[0105] Optionally, such as Figure 6 and Figure 8 As shown, the end of the support surface 21a that is close to the frame piece 3 and faces the glue structure 4 has a rounded corner 21b, and the diameter of the rounded corner 21b is not less than 0.13 mm and not more than 0.17 mm.

[0106] In this embodiment, the end of the support surface 21a near the frame member 3 and facing the adhesive structure 4 has a rounded corner 21b, which can prevent damage to the display component 1 due to a right angle and help protect the integrity of the display component 1. The diameter of the rounded corner 21b is not less than 0.13 mm and not more than 0.17 mm. The diameter of the rounded corner 21b is within this range, which can facilitate a natural transition of the rounded corner 21b and help avoid the problem of reduced adhesive strength due to an excessively large diameter of the rounded corner 21b.

[0107] It should be noted that when the support surface 21a is the first curved surface, the end of the first curved surface that is close to the frame 3 and faces the adhesive structure 4 needs to be rounded 21b, because the first curved surface needs to be smoothly transitioned. If it is a sharp corner, it cannot be formed and will damage the display component 1.

[0108] Optionally, on at least one side of the display device 100, the ratio of the width of the adhesive structure 4 extending from the frame member 3 into the interior of the display device 100 to the minimum thickness of the adhesive structure 4 is not less than 1:3 and not more than 1.3:3. The width of the adhesive structure 4 along the direction parallel to the back panel 5 is not less than 0.6 mm and not more than 0.9 mm, and the minimum thickness of the adhesive structure 4 is not less than 0.2 mm and not more than 0.3 mm.

[0109] In this embodiment, the adhesive structure 4 is disposed in the non-display area BB of the display panel. The ratio of the width of the adhesive structure 4 extending from the frame 3 into the interior of the display device 100 to the minimum thickness of the adhesive structure 4 is not less than 1:3 and not greater than 1.3:3. This is a relatively large range of width-to-thickness ratio that the adhesive structure 4 can achieve. When the width of the adhesive structure 4 is constant, the thicker the adhesive structure 4, the stronger the adhesive force and the better the elasticity of the adhesive structure 4.

[0110] The width of the adhesive structure 4 along the direction parallel to the back panel 5 is not less than 0.6 mm and not more than 0.9 mm. Within this width range, it is beneficial to ensure that the adhesive structure 4 is only set in the non-display area BB, avoiding the problem of dark bezels at large viewing angles caused by the adhesive structure 4 being set in the display area AA. It is also beneficial to ensure the adhesion of the adhesive structure 4 to the middle frame assembly 2 and the display assembly 1. The thickness of the adhesive structure 4 is not less than 0.2 mm and not more than 0.3 mm. Within this thickness range, it is beneficial to ensure the stability of the connection between the adhesive structure 4 and the middle frame assembly 2 and the display assembly 1, and to avoid the risk of glue separation and light leakage directly from the glue separation point during the high-temperature aging process of the display device 100.

[0111] When the support surface 21a is flat, the adhesive structure 4 is constant, which helps to ensure the flatness of the connection surface between the display component 1 and the middle frame component 2, and thus helps to ensure the flatness of the display device 100. When the support surface 21a is curved, the thickness of the adhesive structure 4 varies continuously in the range of 0.2 mm to 0.3 mm, and the thickness of the adhesive structure 4 at the thinnest point is not less than 0.2 mm, which helps to ensure the adhesion.

[0112] In the above methods, the phenomenon of dark frame under large viewing angle is eliminated by setting the support surface 21a as a curved surface. When the support surface 21a is a plane, a transparent part 25 can be added to increase the amount of light entering, which can also eliminate the phenomenon of dark frame under large viewing angle. The specific solutions are as follows.

[0113] Optionally, such as Figure 4 and Figure 9 As shown, the middle frame assembly 2 also includes a transparent part 25, and the middle frame assembly 2 contacts the adhesive structure 4 through the first wrapping portion 251 of the transparent part 25.

[0114] In this embodiment, by providing a first wrapping portion 251 of the transparent component 25, the first wrapping portion 251 wraps the support surface 21a and contacts the adhesive structure 4. Since both the first wrapping portion 251 and the adhesive structure 4 are transparent, more light can pass through the first wrapping portion 251, which can eliminate the phenomenon of dark edges of the display component 1 under large viewing angles.

[0115] Optionally, the thickness of the first wrapping portion 251 of the transparent part 25 is not less than 1 mm and not more than 2 mm.

[0116] In this embodiment, the thickness of the first wrapping portion 251 of the transparent part 25 is not less than 1 mm and not more than 2 mm. The thickness of the first wrapping portion 251 is within this range, which is conducive to the emission of sufficient light and helps to eliminate the phenomenon of dark frame. The thickness of the first wrapping portion 251 is not more than 2 mm and the thickness is uniform, which can avoid the phenomenon of warping under high and low temperature impact and help to ensure the stability of the first wrapping portion 251.

[0117] Optionally, the mid-frame assembly 2 includes a support portion 21 and a fixing portion 22. The support surface 21a is located on the side of the support portion 21 closer to the display assembly 1; the exposed surface 23a is located on the support portion 21; the fixing portion 22 is located on the side of the support portion 21 away from the display assembly 1; the back plate 5 includes a back plate body 51 extending in the same direction as the display assembly 1, and a back plate flange 52 extending from the edge of the back plate body 51 toward the display assembly; the back plate flange 52 is bent to form a platform portion 521 located between the back plate body 51 and the mid-frame assembly 2, and the fixing portion 22 is abutted against the platform portion 521.

[0118] In this embodiment, the stability of the middle frame assembly 2 and the back plate 5 is enhanced by the fixing part 22 of the middle frame assembly 2 abutting against the platform part 521 of the back plate 5.

[0119] Optionally, the side of the middle frame assembly 2 closest to the side frame 3 can be detachably connected to the side frame 3 and can be fixed by bolts, which are used to fix the middle frame assembly 2 and the side frame 3.

[0120] Optionally, such as Figure 1 and Figure 4 As shown, part of the frame member 3 can be abutted against the platform part 521, which can improve the connection strength between the frame member 3 and the back plate 5.

[0121] Optionally, the support portion 21 includes a support body and a transparent element 25. The transparent element 25 covers the support body on the support surface 21a and the exposed surface 23a. The transparent element 25 covers at least a portion of the support body on the side of the support body near the frame element 3. The portion of the transparent element 25 covering the support surface 21a and the exposed surface 214 is set to a glossy surface, and the contact surface between the transparent element 25 and the frame element 3 is set to a frosted surface.

[0122] In this embodiment, the process of the transparent component 25 wrapping the support body is as follows: the support body is extruded using an aluminum extrusion die, and then the support body is placed into a plastic mold to prepare the transparent component 25. This preparation process can improve the adaptability of the transparent component 25 and the support body, and can improve the tight wrapping of the transparent component 25 on the support body to improve the stability of the support part 21. The transparent component 25 wraps the support body through the support surface 21a, the exposed surface 23a, and at least a portion of the area on the side of the support body near the frame component 3, i.e., the three sides of the support body, which can help improve the overall strength of the support part 21, and can further improve the wrapping stability of the transparent component 25 and the support body, and can prevent the transparent component 25 from detaching from the support body. Specifically, the transparent part 25 wraps around both ends of the support body on the side of the support body near the frame part 3, which can improve the stability of the wrapping; the middle area of ​​the support body, which is not wrapped by the transparent part 25, needs to be fixed to the frame part 3 on the side of the support body near the frame part 3. The fixing method can be bolts and screws, etc., so that the support body is directly fixed to the frame part 3, which can improve the stability of the support part 21 and the frame part 3.

[0123] The portion of the transparent element 25 that covers the support surface 21a and the exposed surface 214 is made smooth to facilitate the smooth entry and reflection of light into the transparent element 25, thereby increasing the amount of light and solving the problem of a dark frame. The contact surface between the transparent element 25 and the frame element 3 is made frosted so that light is evenly reflected back into the support portion 21 through the frosted surface, thereby improving the utilization rate of light.

[0124] Optionally, such as Figure 9 As shown, the display device 100 also includes a light-shielding structure 6, which is disposed at least between the frame member 3 and the non-display area of ​​the display component 1.

[0125] In this embodiment, a light-shielding structure 6 is provided between the frame member 3 and the non-display area of ​​the display component 1, which can help solve the problem of light leakage at the edge of the display component 1 and ensure the display effect of the display device.

[0126] Alternatively, the light-shielding structure 6 can have the following two shapes, as detailed below:

[0127] In one possible implementation method, such as Figure 9 As shown, the light-shielding structure 6 includes a light-shielding adhesive structure 61; the light-shielding adhesive structure 61 is disposed between the frame member 3 and the non-display area of ​​the display component 1; the light-shielding adhesive structure 61 also covers at least a portion of the surface of the light-emitting side of the display component 1, and the orthographic projection of the light-shielding adhesive structure 61 on the display panel 11 is located in the non-display area; the minimum distance between the orthographic projection of the light-shielding adhesive structure 61 on the display panel 11 and the display area of ​​the display component 1 is no greater than 0.1 mm.

[0128] In this embodiment, the light-shielding adhesive structure 61 covers at least a portion of the surface of the light-emitting side of the display component 1, and the orthographic projection of the light-shielding adhesive structure 61 on the display component 1 is located in the non-display area. Therefore, when viewed from the front of the display device 100, the "borderless" feel of the non-display area of ​​the display device 100 is enhanced. The minimum distance between the orthographic projection of the light-shielding adhesive structure 61 on the display component 1 and the display area of ​​the display component 1 is no greater than 0.1 mm. Within this width range, the "borderless" feel of the non-display area of ​​the display device 100 is further enhanced, and it is also ensured that the light-shielding adhesive structure 61 is in the non-display area, thus avoiding any impact on the display effect of the display device 100.

[0129] Specifically, the width of the light-shielding adhesive structure 61 is not less than 1 mm and not more than 1.1 mm. The light-shielding adhesive structure 61 includes black hot melt adhesive, which is fused together with the black matrix in the non-display area, further enhancing the visual sense of borderlessness. It should be noted that the light-shielding adhesive structure 61 is not limited to using black hot melt adhesive; any adhesive that can block light leakage from the display component 1 is acceptable, and no limitations are imposed here.

[0130] Optionally, the light-shielding structure 6 also includes a blocking structure 62, which is disposed between the display component 1 and the frame component 3, and is located on the side of the light-shielding adhesive structure 61 near the middle frame component 2.

[0131] In this embodiment, by providing a blocking structure 62 on the side of the light-shielding adhesive structure 61 near the middle frame assembly 2, the light-shielding adhesive structure 61 is prevented from flowing towards the middle frame assembly 2. This avoids defects such as shrinkage marks and pits on the light-shielding adhesive structure 61 and helps maintain a full and smooth adhesive surface. Specifically, the blocking structure 62 can be black high-compression foam tape.

[0132] Another possible implementation method, such as Figure 11 As shown, the light-shielding structure 6 includes a black filling structure 63, which is also disposed on the light-emitting side of at least a portion of the non-display area.

[0133] In this embodiment, when the display device 100 is large in size and the viewing distance is far (greater than 1.5 meters), the light-shielding structure 6 can be a black filling structure 63, which is directly pasted into the gap between the display component 1 and the frame component 3. Before filling, the thickness of the initial black filling structure is greater than the width of the gap, which ensures that the black filling structure 63 formed after filling will fill the gap completely, thereby preventing side light leakage from the display component 1.

[0134] It should be noted that the black filling structure 63 can be black foam.

[0135] Optionally, such as Figure 5As shown, the display assembly 1 includes a display panel 11 and an optical film 12 located on the light-incident side of the display panel 11; the display panel 11 includes a first polarizer 111, a color filter substrate 112, a liquid crystal layer (not shown), an array substrate 113, and a second polarizer 114, which are sequentially stacked from the light-emitting side to the light-incident side of the display panel 11; the optical film 12 is bonded to the second polarizer 114.

[0136] In this embodiment, at the front end of the production line for manufacturing the display device 100, the optical film 12 is first bonded to the light-incident side of the display panel 11, that is, the display component 1 is manufactured first, and then the display device 10 is manufactured, that is, the entire display component 1 is bonded to the middle frame component 2, and the frame component 3 is fixed to the middle frame component 2 and the four sides of the display component 1. This can help improve the production efficiency of the display device, shorten the manufacturing cycle of the display device 100, and reduce labor costs.

[0137] Furthermore, the optical film 12 is flush-fitted with the four edges of the display panel 11, which helps to avoid the phenomenon of bright edges or dark frames on the display panel caused by the edge of the optical film 12 being smaller than the edge of the display panel 11. The optical film 12 serves to homogenize the light incident on the display panel 11.

[0138] Optionally, the optical film 12 is a composite film. The process of bonding the display panel 11 with the optical film 12 is as follows: the initial optical film and the initial second polarizer 114 are fully bonded together. After bonding, the film is cut to form the bonded optical film 12 and the second polarizer 114. The side of the array substrate 113 away from the color filter substrate 112 is bonded to the side of the second polarizer 114 away from the optical film 12. Then, the first polarizer 111 is bonded to the side of the color filter substrate 112 away from the array substrate 113. This completes the fabrication of the display component 11. Because the bonding of the optical film 12 and the second polarizer 114 is done by cutting the whole, this fabrication process can help ensure the integrity of the optical film 12 and the second polarizer 114, avoid separation of the optical film 12 and the second polarizer 114, and help ensure the bonding yield of the display component 11.

[0139] Optionally, the material of the frame component 3 includes at least one of aluminum, stainless steel and SGLC, and / or the material of the middle frame component 2 includes aluminum.

[0140] In this embodiment, SGLC is hot-dip galvanized aluminum alloy sheet, which is also a type of galvanized sheet. Galvanized sheet refers to steel sheet with a layer of zinc on its surface. Aluminum material can be extruded, and various shapes and thicknesses can be formed through aluminum extrusion. Stainless steel and galvanized aluminum sheets can be stamped, and during the stamping process, stainless steel and galvanized aluminum sheets have equal thicknesses. It should be noted that all the above materials can be treated with painting, electroplating, anodizing, etc., according to the positioning of the display device 100.

[0141] It should be noted that, in addition to the above-mentioned materials, the frame component 3 can also include aluminum-magnesium alloy, magnesium alloy, and titanium alloy.

[0142] Optionally, the frame member 3 includes a fastening part 31 and a narrow side part 32 that are connected to each other. The fastening part 31 is located on the periphery of the support member 21 and is detachably connected to the support member 21, while the narrow side part 32 is located on the periphery of the display assembly 1.

[0143] When the material of frame component 3 is aluminum, such as Figure 12 As shown, the side of the narrow edge 32 away from the non-display area is an arc 321, and the side of the arc 321 closer to the back plate 5 is closer to the display component 1 than the side away from the back plate 5.

[0144] In this embodiment, since the side of the narrow edge 32 away from the non-display area is an arc 321, the visual effect of the narrow edge of the display device can be enhanced when viewed from the front of the display device.

[0145] When the material of the frame component 3 is at least one of stainless steel and galvanized aluminum sheet, such as Figure 10 As shown, the narrow side 32 has a uniform thickness structure, which is conducive to one-time stamping and shortens the production cycle.

[0146] By applying the embodiments of this application, at least the following beneficial effects can be achieved:

[0147] 1. The embodiment of this application provides a method to connect the display component to the middle frame component in the thickness direction of the display component, wherein the middle frame component and the frame component are independent components, which facilitates rework operations and helps protect the integrity of the display component.

[0148] 2. The first curved surface provided in this application embodiment is a smoothly transitioned curved surface. As the first curved surface moves from the non-display area to the display area, it moves further and further away from the display component, and the thickness of the adhesive structure becomes thicker and thicker. Moreover, the adhesive structure is transparent adhesive, which can help reduce or eliminate the phenomenon of dark edges under a large viewing angle, and is beneficial to improving the display effect of the display component.

[0149] 3. The embodiment of this application provides a first wrapping part with a transparent component. The first wrapping part wraps the support surface and contacts the adhesive structure. Since both the first wrapping part and the adhesive structure are transparent, more light can pass through the first wrapping part, which can eliminate the phenomenon of dark edges of the display component under large viewing angles.
