Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a display device. Background Technology

[0002] To reduce overall cost, some LCD modules have eliminated the mid-frame structure. The top, left, and right sides are directly connected to the back panel 01 via a C-bend or F-bend structure 011. The LCD panel 03 is then bonded and fixed to the bent surface using panel tape 02. Figure 1 The diagram shows the structure at the top-side F-bend, where the top, left, and right sides form a ring-shaped groove. The diffuser plate 04 is horizontally inserted into the F-bend groove from the ground side in the direction of the arrow. To prevent displacement of the diffuser plate 04 during side or corner drops of large machines, VHB tape (double-sided foam adhesive) 05 is designed inside the top-side F-bend groove of the backplate and on the ground-side diffuser plate mounting plane a. When the module backlight is a lamp board 06, the lamp board 06 has a built-in reflector. To ensure proper light output, side reflectors 07 need to be fixed to the beveled surfaces around the backplate using double-sided adhesive. The side reflectors 07 are planar structures, slightly shorter than the sidewalls of the backplate, mainly affected by the depth of the backplate cavity.

[0003] When the diffuser plate 04 is horizontally inserted into the F-bending groove from the ground side, it will experience... Figure 2 The process is illustrated, with solid rectangles representing the incomplete installation state and dashed rectangles representing the final installed state. VHB tape 05 is approximately 0.4mm thick with a rectangular cross-section, forming a thickness step. During installation, diffuser plate 04 needs to climb this VHB tape 05 thickness step to reach the dashed line position, ensuring adhesion between the lower surface of diffuser plate 04 and the upper surface of VHB tape 05. The large diffuser plate's top side will sag due to its own weight, causing it to adhere tightly to the diffuser plate mounting plane within the backplate F bending groove. This increases the difficulty of climbing the VHB tape thickness step, often requiring multiple pulls and shakes to achieve proper installation, significantly impacting production line efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A first reflective portion, the first reflective portion comprising:

[0013] The main body is located on the first side wall;

[0014] The first extension is connected to the main body and is located on the side of the first platform portion away from the first sidewall along the first direction, and its stiffness is less than that of the main body portion;

[0015] The first extension bends away from the second sidewall under the action of the pushed-in diffuser plate. After bending, the maximum distance of the first extension from the first platform portion along the first direction is greater than the thickness of the first adhesive portion along the first direction. The first direction is perpendicular to the first platform portion.

[0016] The display device in the above technical solution has the following beneficial effects: Since the first reflective part disposed on the first sidewall has a first extension, the stiffness of the first extension is less than that of the main body. During the process of the diffuser plate being pushed from the side where the second sidewall is located to the side where the first sidewall is located, the diffuser plate will push the first extension to bend away from the second sidewall. The maximum distance between the first extension after bending and the first platform part is greater than the thickness of the first adhesive part. At this time, the diffuser plate will be raised by the first extension after bending, forming a height difference with the first adhesive part, so that the diffuser plate crosses the thickness step of the first adhesive part and is smoothly located on the side of the first adhesive part away from the first platform part. Under external pressure, the diffusion plate and the first adhesive part can be bonded, which can improve the production efficiency of the display device.

[0031] The display device in the above technical solution has the following beneficial effects: Under the push of the diffuser plate, multiple bendable parts of the first extension bend along the bending line, and each bending line can be bent individually, which can make the first extension form a partially segmented arc state. The diffuser plate, raised by the bent first extension, can cross the thickness step of the first adhesive part and smoothly enter the side of the first adhesive part opposite to the first platform part, facilitating the bonding of the diffuser plate to the first adhesive part and improving the production efficiency of the display device.

[0032] In some embodiments of this application, the first extension has positioning portions on both sides along a third direction, the positioning portions being used to position the first reflective portion on the back plate.

[0033] The display device in the above technical solution has the following beneficial effects: by providing a positioning part on the first extension, the assembly position of the first reflective part on the back plate can be positioned when fixing the main body of the first reflective part.

[0036] The display device in the above technical solution has the following beneficial effects: a hollow area is provided on the first extension, which can avoid the first adhesive part after the first extension is bent, thus preventing the first extension from covering the first adhesive part after bending, and facilitating the bonding between the first adhesive part and the diffuser plate.

Detailed Implementation

[0077] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0078] Please refer to Figures 3 to 6 This utility model provides a display device, including:

[0079] The back plate 1 includes a receiving portion 11 and a first platform portion 1211. The receiving portion 11 has opposing first sidewalls 111 and second sidewalls inside. The first platform portion 1211 is located on the light-emitting side of the receiving portion 11 and is connected to the first sidewall 111.

[0080] The first adhesive portion 2 is located on the first platform portion 1211;

[0081] The diffuser plate 3 is pushed in from the side where the second sidewall is located toward the side where the first sidewall 111 is located along the plane where the first platform portion 1211 is located, so as to bond with the first adhesive portion 2;

[0082] The first reflective part 4 includes a main body part 41 and a first extension part 42. The main body part 41 is located on the first side wall 111. The first extension part 42 is connected to the main body part 41 and is located on the side of the first platform part 1211 away from the first side wall along the first direction. The stiffness of the first extension part 42 is less than that of the main body part 41.

[0083] The first extension 42 is bent away from the second sidewall under the action of the pushed diffuser plate 3. After bending, the maximum distance of the first extension from the first platform 1211 along the first direction is greater than the thickness of the first adhesive part 2 along the first direction. The first direction is perpendicular to the first platform 1211.

[0084] In the display device provided in this embodiment, the first sidewall 111 on the back plate 1 is opposite to the second sidewall, and the diffuser plate 3 can be pushed in from the side where the second sidewall 112 is located toward the side where the first sidewall 111 is located so as to bond it to the first adhesive part 2.

[0085] Wherein, since the first reflective part 4 provided on the first sidewall 111 has a first extension part 42, the stiffness of the first extension part 42 is less than that of the main body part 41. During the process of the diffuser plate 3 being pushed from the side where the second sidewall is located to the side where the first sidewall 111 is located, the diffuser plate 3 will push the first extension part 42 to bend away from the second sidewall. The maximum distance between the first extension part and the first platform part after bending can be greater than the thickness of the first adhesive part.

[0086] The diffuser plate 3 is raised by the first extension after bending, which can form a height difference h0 with the first adhesive part 2. This allows the diffuser plate 3 to cross the thickness step of the first adhesive part 2 and smoothly be positioned on the side of the first adhesive part 2 away from the first platform part 1211. Under external pressure, the diffuser plate 3 can be bonded to the first adhesive part 2, which can improve the production efficiency of the display device.

[0087] It should be noted that stiffness refers to a material's ability to resist bending deformation or maintain its original shape, and is usually used to describe a material's bending resistance under stress. In this embodiment, the stiffness of the first extension of the first reflective portion being less than that of the main body portion means that the first extension portion's ability to resist bending deformation under stress is less than that of the main body portion. The fact that the stiffness of the first extension portion is less than that of the main body portion facilitates the bending of the first extension portion when pushed by the diffuser plate 3.

[0088] In one specific embodiment, in the display device, the receiving portion 11 of the back panel 1 may have a bottom surface and four side walls connected to the bottom surface. The bottom surface and the four side walls can cooperate to form a receiving cavity. The four side walls include a first side wall 111, a second side wall, a third side wall and a fourth side wall. The first side wall 111 is disposed opposite to the second side wall, and the third side wall is disposed opposite to the fourth side wall.

[0089] In practical applications, the first sidewall 111 can be located on the top side of the display device, and the second sidewall can be located on the ground side of the display device.

[0090] A light panel can be installed on the bottom surface of the back panel to provide a light source. To ensure the light output, the light panel can be equipped with a reflector, and reflectors are also required on the four side walls.

[0091] To reduce the overall cost of the display device, the display device can eliminate the mid-frame structure. In this case, the three edges of the back panel 1 can be provided with bending portions 12, and one edge can be without bending. Specifically, the bending portion 12 can include a support plate 121. The support plate 121 can be connected to the first side wall 111, the third side wall, and the fourth side wall of the receiving portion 11, but not to the second side wall. The first platform portion 1211 is part of the support plate 121, connected to the first side wall 111, and has the same orientation as the light outlet of the receiving portion 11.

[0092] Specifically, a straight plate can be connected to the second side wall 112. The two ends of the straight plate can be connected to the support plate 121 of the bending part 12. The support plate 121 and the straight plate can together form a mounting plane for supporting the diffuser plate 3. The orientation of the mounting plane is the same as the orientation of the light outlet of the receiving part 11. The first platform part 1211 is part of the mounting plane.

[0093] Specifically, the bending portion 12 also has a support plate 122, which can be located facing the mounting plane. The side of the support plate 122 away from the mounting plane can be used to support the liquid crystal display panel. The support plate 122 and the support plate 121 can cooperate to form an annular groove.

[0094] The bending portion 12 can be F-shaped, such as... Figure 3 As shown, it can also be C-shaped, and the bent part 12 also has a vertical plate connected to the support plate 121 and the bearing plate 122.

[0095] Specifically, the diffuser plate 3 is assembled into the display device. The diffuser plate 3 is pushed into the annular groove from the side where the first sidewall 111 is located along the mounting plane toward the side where the second sidewall is located, and then bonded to the first adhesive part 2 on the first platform part 1211.

[0096] In order to avoid the diffuser plate 3 needing to climb the thickness step of the first adhesive part 2 during the process of pushing it into the display device, this embodiment provides a first reflective part 4, which includes a main body part 41 and a first extension part 42. The stiffness of the first extension part 42 is less than that of the second extension part 43.

[0097] When the display device is not assembled with the diffuser plate 3, the main body 41 of the first reflective part 4 is disposed on the first side wall 111 of the back plate 1, and the first extension 42 of the first reflective part 4 can extend out of the receiving part 11 of the back plate 1. The height of the first extension 42 is higher than the height of the first platform part 1211.

[0098] like Figure 5 and Figure 6 As shown, during the process of assembling the diffuser plate 3 into the display device, it is pushed in along the mounting plane from the side where the second sidewall is located toward the side where the first sidewall 111 is located. The end of the diffuser plate 3 will contact the first extension 42 of the first reflective part 4. After the diffuser plate 3 is pushed, since the stiffness of the first extension 42 is less than that of the main body 41, the diffuser plate 3 can push the first extension 42 to bend away from the second sidewall.

[0099] The first extension 42 after bending can raise the diffuser plate 3, so that there is a height difference h0 between the diffuser plate 3 and the first adhesive part 2. When the diffuser plate 3 is pushed into the side opposite to the first platform part 1211 of the first adhesive part 2, the diffuser plate 3 can be manually pressed to make it bond with the first adhesive part 2. This can avoid the problem of needing to climb the steps when the diffuser plate 3 is pushed into the display device, and can facilitate the assembly of the diffuser plate 3 and the first adhesive part 2.

[0100] This utility model also provides a display device, including:

[0101] The back plate 1 includes a receiving portion 11 and a first platform portion 1211. The receiving portion 11 has opposing first sidewalls 111 and second sidewalls inside. The first platform portion 1211 is located on the light-emitting side of the receiving portion 11 and is connected to the first sidewall 111.

[0102] The first adhesive portion 2 is located on the first platform portion 1211;

[0103] The diffuser plate 3 is located on the side of the first adhesive portion 2 away from the first platform portion 1211, so as to be bonded to the first adhesive portion 2;

[0104] The first reflective part 4 includes a main body part 41 and a first extension part 42. The main body part 41 is located on the first side wall 111, and the first extension part 42 is connected to the main body part 41 and is located on the side of the first platform part 1211 away from the first side wall along the first direction. The stiffness of the first extension part 42 is less than that of the main body part 41.

[0105] The first extension 42 is bent toward the side away from the second sidewall, and the first extension 42 abuts against the first platform 1211 and the diffuser plate 3 on both sides along the first direction.

[0106] In the display device provided in this embodiment, since the first reflective part 4 disposed on the first sidewall 111 has a first extension part 42, the rigidity of the first extension part 42 is less than that of the main body part 41. The first extension part 42 is bent toward the side away from the second sidewall. The first extension part 42 abuts against the first platform part 1211 and the diffuser plate 3 on both sides along the first direction. The first extension part 42 can raise the diffuser plate 3 so that the diffuser plate 3 crosses the thickness step of the first adhesive part 2 and is smoothly located on the side of the first adhesive part 2 away from the first platform part 1211, thereby realizing the bonding between the diffuser plate 3 and the first adhesive part 2 and improving the production efficiency of the display device.

[0107] Specifically, the first extension 42 is bent toward the side away from the second sidewall. It can be generated by the thrust of the diffuser plate 3 during the process of pushing the diffuser plate 3 in, or it can be generated in other ways. There are no restrictions here, and it depends on the actual situation.

[0108] Specifically, the first reflective part 4 can be the entire reflective sheet.

[0109] In the display device provided in this embodiment, such as Figure 4 The diagram shown is a plan view of the first reflective part 4 in a straight state. The first extension 42 of the first reflective part 4 may include a plurality of bendable parts arranged at intervals along the second direction. The bendable parts may include a plurality of bending lines 421 arranged along the third direction. The bending lines 421 extend along the third direction, and the first extension 42 is disconnected at the bending lines 421.

[0110] The first edge of the first extension 42 is connected to the main body 41, the second edge of the first extension 42 is located on the side away from the main body 41, the second direction is the arrangement direction of the first edge and the second edge, and the third direction is the extension direction of the first edge.

[0111] Specifically, after the first reflective part 42 in a flat state is assembled onto the back plate, the first extension part 42 extends into the receiving part. The multiple bendable parts of the first extension part 42 can be bent along the bending line 421 under the action of the pushed diffuser plate 3. This allows the maximum distance between the bent first extension part 42 and the first platform part 1211 in the first direction to be greater than the thickness of the first adhesive part 2 in the first direction. This can be used to raise the diffuser plate 3, making it easier for the diffuser plate 3 to bond with the first adhesive part 2.

[0112] During the assembly of the diffuser plate 3 into the display device, the first extension 42, pushed by the diffuser plate 3, causes multiple bendable portions 12 to bend along bending lines 421. Each bending line 421 can be bent individually, forming partial arc shapes. The diffuser plate 3, lifted by the bent first extension 42, can cross the thickness step of the first adhesive portion 2 and smoothly enter between the connecting plate and the support plate 122, facilitating the bonding of the diffuser plate 3 to the first adhesive portion 2 and improving the production efficiency of the display device.

[0113] In the first reflective part 4 described above, since the first extension part 42 has a plurality of bendable parts arranged at intervals along the second direction, each bendable part may have a plurality of bending lines 421 arranged along the third direction, each bending line 421 may be folded individually, and the structure of the bending line 421 may make the stiffness of the first extension part 42 less than that of the main body part 41.

[0114] Specifically, the multiple bendable portions on the first extension 42 can divide the first extension 42 into multiple micro segments along the second direction. The smaller the distance between adjacent bendable portions, the more refined the differentiation of the first extension 42.

[0115] Considering the actual processing conditions and the strength of the reflective sheet, the spacing between two adjacent bendable portions 12 can be 0.5mm to 1mm. The length L1 of the bending line 421 can be 5mm to 10mm, and the distance L2 between two adjacent bending lines 421 along the third direction can be 5mm to 10mm.

[0116] In this embodiment, the width d1 of the first extension 42 on the first reflective part 4 along the second direction can be determined according to the actual display device used, and is not limited here.

[0117] Specifically, the bending lines 421 in two adjacent bendable sections can be set opposite to each other or staggered. There are no restrictions here, and it depends on the actual situation.

[0118] In the display device provided in this embodiment, such as Figure 7 As shown, the first extension 42 may have positioning parts 422 on both sides along the third direction. The positioning parts 422 are used to position the first reflective part 4 on the back plate 1.

[0119] In the prior art, the side reflector is positioned by engaging with a groove at the bottom of the receiving part.

[0120] In the display device provided in this embodiment, a positioning part 422 can be provided on the first extension 42, and when the main body 41 of the first reflective part 4 is fixed, the assembly position of the first reflective part 4 can be positioned by the positioning part 422.

[0121] Specifically, such as Figure 7 As shown, the first extension 42 may have positioning notches on both sides along the third direction, and the positioning notches may have bottom edges extending along the third direction, which may be positioning parts 422.

[0122] In the above-mentioned display device, during the assembly of the first reflective part 4, the bottom edge of the positioning notch is flush with the first platform part 1211, which enables the positioning of the first reflective part 4. The design of the positioning notch is simple in structure and easy to operate.

[0123] Specifically, the positioning part 422 can also be a positioning mark, etc.; during the assembly of the first reflective part 4, aligning the positioning mark with the first platform part 1211 can achieve the positioning of the first reflective part 4. Optionally, the positioning part 422 can also be other structures, which are not limited here and depend on the actual situation.

[0124] Specifically, such as Figure 3 As shown, the display device also includes a second adhesive part 5, which can be located on the first side wall 111 and adjacent to the first platform part 1211; the main body part 41 of the first reflective part 4 can be bonded to the first side wall 111 through the second adhesive part 5 to fix the first reflective part 4.

[0125] In this embodiment, since the diffuser plate 3 will make hard contact with the first extension 42 of the first reflective part 4 during the assembly into the display device, the first extension 42 will be squeezed at the connection between the first platform part 1211 and the first side wall 111. In order to prevent the first reflective part 4 from lifting and affecting the display effect, when fixing the first reflective part 4, the second adhesive part 5 can be set close to the first platform part 1211 and bonded along the edge where the receiving part 11 is connected to the first platform part 1211, so as to achieve good fixation of the first reflective part 4.

[0126] Specifically, the second adhesive part 5 can be double-sided tape. Optionally, the width of the double-sided tape can be 16mm, which is not limited here and can be determined according to the actual situation.

[0127] In addition, in this embodiment, after the first extension 42 of the first reflective part 4 is bent, it is relatively soft and has a small force on the diffuser plate 3 after it is bonded to the first adhesive part 2, which can prevent the diffuser plate 3 from falling off the first adhesive part 2.

[0128] In the display device provided in this embodiment, the first adhesive part 2 can be VHB tape.

[0129] In practical applications, VHB tape is often applied using tooling. The application position can be based on a distance of d2 from the inner wall of the vertical plate, where d2 = 2mm.

[0130] Considering the impact of display device bezel width, in display devices with large bezel widths, such as... Figure 3 As shown, the position of the first adhesive portion 2 inside the bending portion 12 can be far away from the receiving portion 11. At this time, the shape of the bendable portion on the first reflective portion 4 can be complete and regular.

[0131] At this time, after the first extension 42 is bent, its position can be such that the edge of the first extension 42 away from the main body 41 abuts against the first platform 1211, and is located between the first adhesive part 2 and the receiving part 11, as shown below. Figure 3 As shown, it can maintain the adhesion between the diffuser plate 3 and the first adhesive part 2 without affecting the adhesion.

[0132] However, in display devices with narrow bezels, such as Figure 8 As shown, the position of the first adhesive part 2 inside the bending part 12 will be close to the receiving part 11. After the first reflective part 4 is bent, it may cover the first adhesive part 2, resulting in a reduction in the adhesive area of ​​the diffuser plate 3 and a decrease in the adhesive strength of the first adhesive part 2.

[0133] At this time, a hollow area 423 can be provided on the first extension 42. After the first extension 42 is bent, the edge of the first extension 42 away from the main body 41 can be located on the side of the first side away from the receiving part 11. The first side is the side of the first adhesive part 2 adjacent to the receiving part 11. The orthographic projection of the hollow area 423 on the first platform part 1211 covers the first adhesive part 2.

[0134] In the aforementioned display device, such as Figure 9 As shown, a hollow area 423 is provided on the first extension 42, which can avoid the first adhesive part 2 after the first extension 42 is bent, so that the first adhesive part is exposed from the hollow area 423, avoiding the first extension 42 from covering the first adhesive part 2 after bending, and facilitating the bonding between the first adhesive part 2 and the diffuser plate 3.

[0135] Specifically, the hollow area 423 can be a clearance notch on the first extension 42, and the clearance notch can be located on the side of the first extension 42 away from the main body 41.

[0136] In the above-mentioned display device, the avoidance notch can prevent the first extension 42 from covering the first adhesive part 2 after bending, which facilitates the bonding between the first adhesive part 2 and the diffuser plate 3, and the structure is simple and easy to manufacture.

[0137] Among them, such as Figure 9 As shown, the bottom edge of the clearance notch can be flush with the bottom edge of the positioning notch; when assembling the first reflective part 4 on the back plate 1, the positioning of the first reflective part 4 can be achieved by making the bottom edges of the clearance notch and the positioning notch flush with the first platform part 1211, which facilitates the bending of the bendable part 12. The structure is simple and easy to manufacture.

[0138] In this embodiment, considering the versatility of the first reflective part 4, the clearance notch can be set at the middle position of the first extension part 42 along the third direction. The first reflective part 4 can be designed in an axisymmetric manner, which can save material costs and facilitate assembly.

[0139] Correspondingly, when attaching the first adhesive part 2, it can be attached according to the attachment position of the first reflective part 4, which facilitates the assembly of the display device. For example, if two side-by-side first reflective parts 4 need to be attached to the first side wall 111, then two first adhesive parts 2 need to be provided on the first platform part 1211, and the first adhesive parts 2 are located at the position opposite to the clearance notch on the bent first extension part 42.

[0140] In addition, since there are errors in the assembly process of the display device, in order to avoid interference between the first adhesive part 2 and the first reflective part 4 caused by the assembly error, the size of the avoidance notch can be designed to be larger than the size of the first adhesive part 2, so that there is a gap between the edge of the first adhesive part 2 and the avoidance notch.

[0141] For example, if the length of the first adhesive part 2 is designed to be 300mm, and the length of the clearance notch along the third direction can be designed to be greater than 400mm, then after the first extension part 42 is bent, the distance between the single side of the first adhesive part 2 and the clearance notch can exceed 50mm, thus avoiding the problem of poor assembly.

[0142] In a specific display device, three edges of the back panel 1 can form bent portions 12, while the other edge needs to cooperate with structures such as the frame and front shell, and is designed as an open structure; for example, such as Figure 10 As shown, the side where the second sidewall 112 of the back plate 1 is located is designed as an open structure. The second sidewall 112 is connected to the flat plate 123. VHB tape 9 can be provided on the flat plate 123 so that the diffuser plate 3 is connected to the flat plate 123.

[0143] When the diffuser plate 3 is pushed into the display device and fixedly bonded to the first adhesive part 2, the diffuser plate 3 can also be bonded to the VHB tape 9 on the flat plate 123, thereby fixing the diffuser plate 3 and facilitating operation.

[0144] Specifically, multiple VHB tapes can be arranged continuously on the flat plate. However, in actual design, the bezel on the side where the second sidewall 112 is located is designed to be narrower, that is, the width d3 of the flat plate is smaller. In this case, the second reflective part on the second sidewall 112 cannot exceed the mounting plane of the diffuser plate 3, otherwise it will easily block the VHB tape on the flat plate and reduce the bonding area.

[0145] In order to improve the versatility of the reflective part and reduce the types of materials, the reflective parts on the other side walls of the receiving part 11 need to use the same type of side reflective sheet.

[0146] Specifically, the first sidewall 111 of the receiving portion 11 on the back plate 1 and the bottom surface 113 of the receiving portion 11 can be connected by the first recess 114, and the second sidewall 112 of the receiving portion 11 on the back plate 1 and the bottom surface 113 of the receiving portion 11 can be connected by the second recess 115.

[0147] The display device may also include a second reflective portion 7, the structure of which may be the same as that of the first reflective portion 4; the main body portion 71 of the second reflective portion 7 may be located on the second side wall 112, and the first extension portion 72 of the second reflective portion 7 may extend into the second recess 115 as the second recess 115 bends.

[0148] In the above-mentioned display device, since the structure of the second reflective part 7 is the same as that of the first reflective part 4, in order to prevent the second reflective part 7 from extending out of the receiving part 11, the positioning method of the second reflective part 7 can be designed to be opposite to that of the first reflective part 4. The first extension 72 of the second reflective part 7 extends into the second recess 115. As the second recess 115 bends, a universal design for the side reflective sheet can be realized.

[0149] The design of the second recess 115 is required to fully accommodate the first extension 72 of the second reflector 7, so as to avoid interference between the first extension 72 of the second reflector 7 and the lamp plate 6 on the bottom surface 113 of the accommodating part 11.

[0150] Specifically, the main body 41 of the second reflective part 7 can be bonded to the second sidewall 112 using double-sided adhesive 8. The position of the double-sided adhesive is not required and depends on the actual situation; for example, it can be located in the middle of the second sidewall 112. The width of this double-sided adhesive can be 16mm, or it can be of other widths; there are no restrictions here, and it depends on the actual situation.

[0151] In practical applications, the depth of the receiving portion 11 of the back panel 1 may be different in different display devices, which directly reflects the different thicknesses of the display devices and thus affects the appearance of the display devices.

[0152] In order to accommodate different depths of receiving portions, i.e. display devices of different thicknesses, in one embodiment, the main body 41 of the first reflective portion 4 may be designed to include a main body area and a bendable area 411, wherein the bendable area 411 is connected between the main body area and the first extension portion 42.

[0153] Specifically, the bendable area 411 may include a plurality of bendable portions arranged sequentially at intervals along the second direction to facilitate bending, such as... Figure 11and Figure 12 As shown.

[0154] like Figure 3 As shown, in the display device, the main body 41 of the first reflective part 4 is bonded to the first sidewall 111, and the first extension 42 extends out of the receiving part 11;

[0155] Accordingly, such as Figure 10 As shown, the structure of the second reflective part 7 is the same as that of the first reflective part 4. The main body 71 of the second reflective part 7 is bonded to the first sidewall 111, and the first extension 72 of the second reflective part 7 extends into the second recess 115, bending as the second recess 115 bends. In this case, the structure of the first reflective part 4 perfectly matches the depth of the receiving part 11.

[0156] If the depth of the receiving portion 11 in the display device is greater than... Figure 10 If the depth of the receiving portion 11 shown is shallow, it will cause part of the main body portion 41 to extend into the first recessed portion 114 when the first reflective portion 4 is bonded, but the main body portion 41 is in a flat state.

[0157] Correspondingly, when the structure of the second reflective part 7 is the same as that of the second reflective part 7, if only the first extension 72 extends into the second recess 115 when the second reflective part 7 is assembled onto the second side wall 112, a portion of the main body 71 of the second reflective part 7 will protrude from the receiving part 11. In this case, the bendable area 411 on the second reflective part 7 can also be extended into the second recess 115, so that the second reflective part 7 does not protrude from the receiving part 11.

[0158] When the structure of the first reflective part 4 is the same as that of the second reflective part 7, the main body 71 of the second reflective part 7 can be bonded to the second side wall 112, and the bendable side of the second reflective part 7 bends along the inner wall of the second recess 115, which can prevent the second reflective part 7 from extending out of the receiving part 11.

[0159] The main body 41 of the first reflective part 4 is designed with a bendable area 411, which enables a universal design that is suitable for different display devices. It has a simple structure, is easy to assemble, reduces the types of materials, and saves costs.

[0160] The structure of the bendable portion of the bendable region 411 can be the same as that of the bendable portion on the first extension 42, so that the bendable region 411 can be bent along the bending line 421.

[0161] Specifically, the spacing between two adjacent bendable parts can be 0.5mm to 1mm, without limitation, depending on the actual situation.

[0162] Specifically, the bending lines 421 in two adjacent bendable portions along the second direction of the bendable area 411 can be arranged parallel to each other or intersecting each other. There is no restriction here, and it depends on the actual situation.

[0163] Specifically, the bending lines 421 of the bendable area 411 and the bending lines 421 on the first extension 42 can be arranged parallel to each other or intersecting each other. There is no restriction here, and it depends on the actual situation.

[0164] Specifically, the first reflective part 4 can have an axisymmetric structure, which is simple and easy to manufacture.

[0165] In this embodiment, the structure of the reflective parts on the third and fourth side walls of the back plate 1 can be the same as the structure of the first reflective part 4, and the assembly method can be the same as the assembly method of the second reflective part 7, which can save materials, facilitate assembly, and realize the universal design of the reflective part.

[0166] Optionally, the reflective portions on the second, third, and fourth sidewalls of the backplate 1 may also have a different structure from the first reflective portion 4. For example, they may not have a typical side reflective sheet structure; this is not a limitation and depends on the actual situation.

[0167] In this embodiment, to accommodate receiving portions of different depths, i.e., display devices of different thicknesses, the first reflective portion 4 can also be designed to have a second extension portion 43, such as... Figure 13 and Figure 14 As shown, the second extension 43 may be located on the side of the main body 41 away from the first extension 42. The second extension 43 includes a plurality of bendable portions arranged sequentially at intervals along the second direction to enable bending.

[0168] like Figure 15 As shown, the second extension 43 can extend into the first recess or be bent within the first recess.

[0169] Specifically, the structure of the first reflective portion 4 may include a main body portion 41, a first extension portion 42, and a second extension portion 43, such as... Figure 13 and Figure 14 As shown, this structure can be applied to display devices with different depths of the receiving portion 11.

[0170] like Figure 16 As shown, when the depth of the receiving part 11 is at the maximum depth h3, when the first reflective part 4 is assembled onto the back plate 1, the first reflective part 4 is positioned flush with the first platform part 1211 through the bottom edge of the positioning notch, the main body part 41 is bonded to the first side wall 111, the first extension part 42 extends out of the receiving part 11, and the second extension part 43 can extend into the first recess 114 without bending.

[0171] like Figure 17 As shown, when the depth of the receiving part 11 is at the intermediate depth h2, the first reflective part 4 is positioned flush with the first platform part 1211 through the bottom edge of the positioning notch, the main body part 41 is bonded to the first side wall 111, the first extension part 42 extends out of the receiving part 11, the second extension part 43 of the first reflective part 4 can extend into the first recess 114, and part of the second extension part 43 bends with the first recess 114.

[0172] like Figure 18 As shown, when the depth of the receiving part 11 is at the minimum depth h1, the main body part 41 is bonded to the first side wall 111, the first extension part 42 extends out of the receiving part 11, the second extension part 43 of the first reflective part 4 can extend into the first recess 114, and the second extension part 43 is bent along with the first recess 114.

[0173] In the second extension 43, the structure of the bendable portion is the same as that of the bendable portion in the first extension 42, and the multiple bendable portions of the second extension 43 can be bent along the bending line.

[0174] Specifically, the width of the second extension 43 along the second direction can be greater than or equal to the width of the first extension 432 along the second direction. This is not limited here and depends on the actual situation.

[0175] Specifically, the structure of the first reflective portion 4 can be designed in a centrally symmetrical manner, in which case the width of the second extension portion 43 along the second direction is equal to the width of the first extension portion 432 along the second direction, such as... Figure 13 and Figure 14 As shown, a universal design can be achieved, without distinguishing between the first extension 42 and the second extension 43, which facilitates the assembly of the first reflective part 4.

[0176] Specifically, when the main body 41 has a bendable area 411, the structure of the first reflective part 4 can also be designed in a centrally symmetrical manner. In this case, the width of the second extension 43 along the second direction is greater than the width of the first extension 432 along the second direction, such as... Figure 19 and Figure 20 As shown, a universal design can be achieved, the structure is simple, there is no need to distinguish between the first extension 42 and the second extension 43, and it is convenient to assemble the first reflective part 4.

[0177] In this embodiment, when the first reflective portion 4 includes the second extension portion 43, the structures of the side reflective sheets on the second sidewall 112, third sidewall, and fourth sidewall of the back plate 1 are different from the structure of the first reflective sheet. Therefore, the structures on the second sidewall 112, third sidewall, and fourth sidewall can be as follows: Figure 7 , Figure 9 , 11 and Figure 12 The structure of the side reflector shown.

[0178] Specifically, the first extension and the bendable area on the second reflective portion 7 can be adjusted to extend into the second recess 115 according to the depth of the receiving portion 11, thereby enabling a universal design for the side reflective sheet and adapting to display devices with different depths of the receiving portion 11.

[0179] Alternatively, the structure of the reflective parts on the second sidewall 112, third sidewall, and fourth sidewall of the backplate 1 can also be a common side reflective sheet structure. There are no restrictions here, and it depends on the actual situation.

[0180] In this embodiment, the display device further includes an optical film, which can be disposed on the side of the diffuser plate away from the mounting plane, and the optical film can be fixed to the diffuser plate with tape.

[0181] Specifically, the optical film material may include lower prism sheets and lower prism sheets stacked in sequence, etc., without limitation, depending on the design.

[0182] In the aforementioned display device, during the assembly of the diffuser plate, the optical film material can be pushed in along with the diffuser plate from the side where the second sidewall is located toward the side where the first sidewall is located.

[0183] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this utility model without departing from the spirit and scope of this utility model. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
