Description

Technical Field

[0001] The utility model relates to the technical field of display equipment, and in particular to a display device. Background Art

[0002] With the trend toward cost-saving designs for overall TV architectures, the current common backlight structure typically involves gluing together optical plates and optical films, which are then inserted parallely into a U-shaped cavity to simplify wiring. However, this approach is primarily used for low- and mid-range products designed with only a single optical film. For high-end products, multiple optical films are required to achieve enhanced brightness or other additional functions. Existing designs cannot secure multiple optical films due to the limited adhesive tape attachment area. Utility Model Content

[0013] Furthermore, at least one optical film is located on a side of the optical plate facing away from the bottom plate, the optical film is provided with a hanging ear notch, and the elastic cantilever passes through and is clamped in the hanging ear notch.

[0014] The display device in the above technical solution has the following beneficial effects: by arranging a connecting bracket in the cavity, the connecting bracket includes a fixing portion and an elastic cantilever, and the fixing portion is fixed to the inner wall of the cavity or the optical plate. The optical film is provided with a hanging ear notch, and the elastic cantilever can be passed through and clamped into the hanging ear notch of the optical film, so that the optical film and the elastic cantilever are relatively fixed. Since the optical plate is fixed to the back plate, the connecting bracket is fixed to the back plate or the optical plate, and the optical film is fixed to the connecting bracket, the optical film and the optical plate are fixed. When assembling multiple optical films, it is only necessary to pass the elastic cantilever through the hanging ear notch of each optical film, so that one or more optical films can be fixed.

[0015] In some embodiments of the present application, the fixing portion is fixedly connected to the inner wall of the cavity;

[0016] The orthographic projection of the optical plate on the first plane partially overlaps with the orthographic projection of the elastic cantilever on the first plane;

[0017] The first plane is a plane parallel to the arrangement direction of the base plate and the support plate.

[0018] The display device of the above technical solution has the following beneficial effects: because the free end of the elastic cantilever can extend to overlap the optical plate, when multiple optical films are installed, the elastic cantilever can be completely inserted into the mounting hole of the bottommost optical film when each optical film is assembled to the back plate via the connecting bracket. This ensures that the elastic cantilever and each optical film are well fixed, thereby ensuring that the optical films are effectively fixed within the back plate.

[0019] In some embodiments of the present application, the fixing portion includes:

[0020] a first fixing plate, fixedly connected to a side of the support plate facing the bottom plate, the elastic cantilever being connected to the first fixing plate; or

[0021] The fixing portion includes:

[0022] a first fixing plate, fixing the side of the support plate toward the bottom plate, the elastic cantilever being connected to the first fixing plate;

[0023] a second fixing plate connected to one end of the first fixing plate and fixedly connected to the second fixing plate; or

[0024] The fixing portion includes:

[0025] a first fixing plate, fixedly connected to a side of the support plate facing the bottom plate, the elastic cantilever being connected to the first fixing plate;

When the fixing portion is designed to include a first fixing plate and a second fixing plate, or to include a first fixing plate, a second fixing plate, and a third fixing plate, the volume of the fixing portion can be increased, thereby improving the strength of the fixing portion and enhancing the overall structural stability of the connecting bracket.

[0033] In some embodiments of the present application, further comprising:

[0034] A guide structure is located on a side of the optical plate facing the optical film, and the guide structure includes:

[0035] The guide surface is located on a side of the guide structure facing the optical film. Along the direction from the opening to the side plate, the dimension between the guide surface and the optical plate gradually increases along the arrangement direction of the bottom plate and the support plate.

[0036] The display device in the above technical solution has the following beneficial effects: by arranging a guide structure on the side of the optical plate facing the optical film, the guide structure is provided with a guide surface. When the optical film is pushed horizontally into the cavity, the guide surface can guide the optical film, so that the optical film can more conveniently squeeze the elastic cantilever, and then the elastic cantilever is stuck in the ear notch of the optical film, thereby improving the convenience and efficiency of assembly.

[0037] In some embodiments of the present application, the orthographic projection of the guide structure on the first plane and the orthographic projection of the elastic cantilever on the first plane partially overlap;

[0038] The first plane is a plane parallel to the arrangement direction of the base plate and the support plate.

[0039] The display device of the above technical solution has the following beneficial effects: based on the provision of a guide structure, the free end of the elastic cantilever is extended to overlap with the guide structure. When multiple optical films are provided, this ensures that when each optical film is assembled to the back panel via the connecting bracket, the elastic cantilever can completely pass through the mounting hole of the bottommost optical film.

[0043] The display device in the above technical solution has the following beneficial effects: the fixing part and the elastic cantilever are designed as an integrated structure, which can improve the overall strength of the connecting bracket. Since the optical film is fixed to the connecting bracket, the connecting bracket structure is stable, ensuring that the optical film will not move at will, thereby improving the structural stability of the display device after assembly.

[0044] In some embodiments of the present application, the connecting bracket is made of metal.

[0045] The display device in the above technical solution has the following beneficial effects: on the basis of the connecting bracket being integrally formed, the material of the connecting bracket is designed to be metal material, which is conducive to the elastic cantilever being squeezed and deformed, and can also ensure that the elastic cantilever has good deformation ability, thereby avoiding the elastic cantilever from breaking during the assembly of the optical film.

DETAILED DESCRIPTION

[0070] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0071] Current display devices, such as LCD televisions, typically use double-sided tape in their backlight structures to attach an optical film to an optical plate. However, due to the complex double-sided tape attachment process, this structure cannot be further widened, making it impossible to secure multiple optical films, resulting in an inability to further improve optical specifications. Furthermore, due to the different expansion rates of the optical film and the optical plate, using double-sided tape to attach the optical film to the optical plate can cause wrinkles in large-scale products due to freezing or high temperatures, resulting in subjective shadows and affecting the display quality.

[0072] Based on this, the present invention provides a display device that can not only realize the assembly of multiple optical films, but also solve the problem of film wrinkles caused by different expansion rates. The above display device is described in detail below with reference to specific embodiments.

[0073] refer to Figure 1 The display device in the embodiment of the present invention may include a back panel 100, an optical plate 200, a connecting bracket 300 and at least one optical film 400, wherein the optical plate 200, the connecting bracket 300 and the optical film 400 are all arranged inside the back panel 100 to be assembled into a backlight structure of the display device.

[0074] The back panel 100 may include a bottom panel 110, side panels 120, and a support panel 130. The side panels 120 are connected to the bottom panel 110, and the support panel 130 is connected to the side of the side panel 120 facing away from the bottom panel 110. In this case, the bottom panel 110, side panels 120, and support panel 130 may cooperate to form a cavity 101 having an opening at one end. The shape of the cavity 101 may be, for example, a U-shape rotated 90 degrees counterclockwise. It is understood that the opening of the cavity 101 is opposite to the side panels 120. The bottom panel 110 and support panel 130 may be considered as the two side walls of the cavity 101, and the side panels 120 may be considered as the bottom wall of the cavity 101.

[0075] In addition, if Figure 1 As shown, the side of the support plate 130 facing away from the bottom plate 110 can also be used to fix the display panel 500 so that the backlight structure at the bottom of the display panel 500 can provide backlight conditions for the display panel 500.

[0076] The optical plate 200 is fixed to the base plate 110, and one end of the optical plate 200 can extend into the cavity 101 through the opening of the cavity 101, so that a portion of the optical plate 200 is located within the cavity 101. The optical film 400 is located on the side of the optical plate 200 facing away from the base plate 110 and can be fixed to the back plate 100 via the connecting bracket 300. When there are two or more optical films 400, the multiple optical films 400 are stacked along the arrangement direction of the base plate 110 and the support plate 130.

[0077] Specifically, continue to refer to Figure 1 The connecting bracket 300 is disposed within the cavity 101 and may include a fixing portion 310 and an elastic cantilever 320. The fixing portion 310 is fixedly connected to the inner wall of the cavity 101. One end of the elastic cantilever 320 is fixedly connected to the fixing portion 310, and the other end extends toward the space between the optical plate 200 and the support plate 130. Furthermore, the extension direction of the elastic cantilever 320 forms an angle with the arrangement direction of the base plate 110 and the support plate 130, which is greater than 0 and less than 90 degrees.

[0078] For reference Figure 1 and Figure 2 The optical film 400 is provided with a hanging ear notch 410. When the optical film 400 is fixed to the back plate 100, the elastic cantilever 320 is inserted into the hanging ear notch 410. Due to the certain angle between the elastic cantilever 320 and the optical film 400, the elastic cantilever 320 can respectively abut against the two opposing inner walls of the hanging ear notch 410, thereby enabling the elastic cantilever 320 to be snapped into the hanging ear notch 410. At this time, since the connecting bracket 300 and the back plate 100 are relatively fixed, the optical plate 200 and the back plate 100 are relatively fixed. The optical film 400 is maintained relatively fixed to the connecting bracket 300 via the elastic cantilever 320, thereby achieving relative fixation between the optical film 400 and the optical plate 200.

[0079] Figure 1 The figure shows a schematic diagram of the structure of two stacked optical films 400. When two or more optical films 400 are provided, each optical film 400 is respectively connected to the elastic cantilever 320 through the ear notch 410, thereby achieving relative fixation between each optical film 400 and the back plate 100. Compared with existing display devices, this embodiment uses a connecting bracket 300 to fix the optical film 400 instead of affixing the optical film 400 to the optical plate 200. This breaks through the limitation on the number of optical films 400 and allows one or more optical films 400 to be provided, which is conducive to improving the optical specifications of the display device. In addition, because the optical film 400 is not directly fixed to the optical plate 200, it will not wrinkle in a freezing or high temperature environment, thereby ensuring the display effect.

[0080] In specific implementation, the fixing part 310 can be fixed to the inner wall of the cavity 101 by bonding, or a limiting structure can be set on the inner wall of the cavity 101 to limit the fixing part 310 by using the limiting structure, so that the fixing part 310 is installed inside the cavity 101 according to a preset position to ensure that the fixing part 310 maintains structural stability in the cavity 101, so as to facilitate the assembly of the optical film material 400.

[0081] For ease of understanding, in the following embodiments, the x direction indicates a direction perpendicular to the side plate 120 , the z direction indicates an arrangement direction of the bottom plate 110 and the support plate 130 , and the x direction is perpendicular to the z direction.

[0082] In some embodiments, reference is made to Figure 1 and Figure 3 The fixing portion 310 may include a first fixing plate 311, which may be fixedly connected to the side of the support plate 130 facing the bottom plate 110. In this case, the elastic cantilever 320 is connected to the side of the first fixing plate 311 facing the bottom plate 110, and the free end of the elastic cantilever 320 extends toward the side plate 120 in a direction perpendicular to the side plate 120, thereby forming a certain angle between the elastic cantilever 320 and the first fixing plate 311.

[0083] On this basis, if Figure 1 As shown, the first fixing plate 311 can be bonded to the first support plate 130 via the first adhesive layer 600, thereby achieving relative fixation between the first fixing plate 311 and the first support plate 130. The area of the first adhesive layer 600 can be equal to the area of the first fixing plate 311 directly opposite the support plate 130, thereby completely covering the bonding area between the first fixing plate 311 and the support plate 130, thereby improving the bonding effect of the first fixing plate 311 and ensuring the fixing effect between the first fixing plate 311 and the support plate 130.

[0084] Alternatively, as another optional embodiment, refer to Figure 4 and Figure 5 , a limiting structure can be set on the first support plate 130 and the side plate 120 to limit the first fixing plate 311 through the limiting structures on both sides, thereby enhancing the fixing effect of the first fixing plate 311.

[0085] The limiting structure on the first support plate 130 may be a first vertical wall structure 131. This first vertical wall structure 131 is located on the side of the first fixing plate 311 facing away from the side plate 120 and protrudes from the side surface of the support plate 130 facing the bottom plate 110. The limiting structure on the side plate 120 may be a first slot 121 provided on the side plate 120, and the first slot 121 extends in a direction perpendicular to the side plate 120. The first end of the first fixing plate 311 abuts against the first vertical wall structure 131, and the second end is engaged in the first slot 121 and abuts against the bottom of the first slot 121. Thus, the first slot 121 can limit the first fixing plate 311 in the z-direction, and the first slot 121 and the first vertical wall structure 131 cooperate to limit the first fixing plate 311 in the x-direction. Of course, the first fixing plate 311 may also be limited in a direction perpendicular to the x-direction and the z-direction, thereby ensuring that the first fixing plate 311 can be fixed in the cavity 101 .

[0086] In this embodiment, the first fixing plate 311 can abut against the side surface of the support plate 130 facing the base plate 110, so that the support plate 130 cooperates with the first card slot 121 in the z direction to limit the first fixing plate 311, thereby enhancing the fixing effect of the first fixing plate 311.

[0087] In some embodiments, reference is made to Figure 6 and Figure 7 The fixing portion 310 may include a first fixing plate 311 and a second fixing plate 312 connected to each other, the second fixing plate 312 is located on the side of the first fixing plate 311 facing the side plate 120, and the elastic cantilever 320 is connected to one end of the first fixing plate 311 away from the second fixing plate 312.

[0088] On this basis, when the connecting bracket 300 is fixed in the cavity 101, the first fixing plate 311 can be fixedly connected to the side of the support plate 130 facing the bottom plate 110, and the second fixing plate 312 can be fixedly connected to the side of the side plate 120 facing the optical plate 200.

[0089] For example, Figure 7 As shown, the support plate 130 is provided with a first vertical wall structure 131, and the first vertical wall structure 131 protrudes from the side surface of the support plate 130 facing the bottom plate 110. The bottom plate 110 is provided with a second card slot 112, and the second card slot 112 extends along the z-direction. When the connecting bracket 300 is fixed in the cavity 101, the end of the first fixing plate 311 away from the second fixing plate 312 abuts against the first vertical wall structure 131, and the first fixing plate 311 abuts against the side surface of the support plate 130 facing the bottom plate 110, and the end of the second fixing plate 312 away from the first fixing plate 311 is engaged in the second card slot 112, and the end of the second fixing plate 312 abuts against the bottom of the second card slot 112. At this time, the second card slot 112 and the first vertical wall structure 131 limit the fixing part 310 in the x direction, and the second card slot 112 and the support plate 130 cooperate to limit the fixing part 310 in the z direction, thereby ensuring the fixing effect of the connecting bracket 300 in the cavity 101.

[0090] Alternatively, as another optional embodiment, refer to Figure 6 and Figure 8The support plate 130 is provided with a first vertical wall structure 131, and the side of the side panel 120 facing the optical plate 200 is provided with a second adhesive layer 700. When the connecting bracket 300 is fixed in the cavity 101, the end of the first fixing plate 311 away from the second fixing plate 312 abuts against the first vertical wall structure 131. The first fixing plate 311 also abuts against the side surface of the support plate 130 facing the bottom plate 110, and the end of the second fixing plate 312 away from the first fixing plate 311 abuts against the side surface of the bottom plate 110 facing the support plate 130. In addition, the side of the second fixing plate 312 facing the side panel 120 is bonded to the second adhesive layer 700. As a result, the second adhesive layer 700 not only cooperates with the first vertical wall structure 131 to limit the fixing portion 310 in the x-direction, but also cooperates with the support plate 130 and the bottom plate 110 to limit the fixing portion 310 in the z-direction.

[0091] The area of the second adhesive layer 700 can be substantially equal to the area of the second fixing plate 312 facing the side plate 120, thereby increasing the contact area between the second fixing plate 312 and the second adhesive layer 700 and enhancing the fixing effect on the second fixing plate 312. The end of the second adhesive layer 700 closest to the bottom plate 110 can also be bonded to the surface of the bottom plate 110 to further enhance the bonding and fixing effect on the second fixing plate 312.

[0092] In some embodiments, reference is made to Figure 9 and Figure 10 The fixing portion 310 may include a first fixing plate 311, a second fixing plate 312 and a third fixing plate 313, the second fixing plate 312 is connected to the side of the first fixing plate 311 facing the side plate 120, the third fixing plate 313 is connected to the end of the second fixing plate 312 away from the first fixing plate 311, and the elastic cantilever 320 is connected to the end of the first fixing plate 311 away from the second fixing plate 312.

[0093] On this basis, when the connecting bracket 300 is fixed in the cavity 101, the first fixing plate 311 can be fixedly connected to the side of the support plate 130 facing the bottom plate 110, the second fixing plate 312 can be fixedly connected to the side of the side plate 120 facing the optical plate 200, and the third fixing plate 313 can be fixedly connected to the side of the bottom plate 110 facing the support plate 130.

[0094] Exemplarily, the support plate 130 is provided with a first vertical wall structure 131, which protrudes from a side surface of the support plate 130 facing the base plate 110. The first fixing plate 311 abuts against the first vertical wall at one end away from the second fixing plate 312. The first fixing plate 311 also abuts against a side surface of the support plate 130 facing the base plate 110. The third fixing plate 313 abuts against the surface of the base plate 110 at a side away from the second fixing plate 312. In other words, in this embodiment, the fixing portion 310 and the two inner walls of the cavity 101 are interference-fitted to retain the fixing portion 310 within the cavity 101, thereby limiting the position of the fixing portion 310 in the z-direction. At the same time, the fixing portion 310 is limited in the x-direction by cooperating with the first vertical wall structure 131.

[0095] Alternatively, as another optional embodiment, refer to Figure 9 and Figure 11 The limiting structure on the bottom plate 110 may include a second vertical wall structure 111 disposed on the bottom plate 110. The second vertical wall structure 111 is concave inward along the z-direction relative to the side surface of the bottom plate 110 facing the support plate 130, so that an abutment surface 113 facing the side plate 120 is formed between the bottom plate 110 and the second vertical wall structure 111. Exemplarily, the side of the second vertical wall structure 111 facing the support plate 130 further has an inclined surface with a certain angle with the x-direction.

[0096] When the fixing portion 310 is fixed to the interior of the cavity 101, the first fixing plate 311 abuts against the side of the support plate 130 facing the bottom plate 110, and the side of the third fixing plate 313 facing away from the second fixing plate 312 abuts against the surface of the bottom plate 110, thereby achieving an interference fit between the fixing portion 310 and the inner wall of the cavity 101. In addition, the portion of the third fixing plate 313 facing the second vertical wall structure 111 can be bent toward the inclined surface and extend along the inclined surface until it abuts against the abutting surface 113. By achieving an interference fit between the fixing portion 310 and the inner wall of the cavity 101 and cooperating with the second vertical wall structure 111, the fixing portion 310 is limited in the x- and z-directions.

[0097] Alternatively, as another optional embodiment, refer to Figure 9 and Figure 12The side of the side panel 120 facing the optical plate 200 is provided with a second adhesive layer 700. When the fixing portion 310 is fixed to the interior of the cavity 101, the first fixing plate 311 abuts against the surface of the support plate 130 facing the bottom plate 110, the side of the third fixing plate 313 facing away from the second fixing plate 312 abuts against the surface of the bottom plate 110, and the side of the second fixing plate 312 facing the side panel 120 is bonded to the second adhesive layer 700. Thus, by creating an interference fit between the fixing portion 310 and the inner wall of the cavity 101 and cooperating with the second adhesive layer 700, the fixing portion 310 can be limited in the x- and z-directions.

[0098] It is worth noting that when assembling the display device in this embodiment, the optical plate 200 and the optical film 400 can be inserted into the cavity 101 in parallel. Figure 13 and Figure 14 Specifically, during assembly, the connecting bracket 300 can be pushed into the interior of the cavity 101 first, and the connecting bracket 300 can be fixed to the cavity 101, and then the optical plate 200 can be inserted into the cavity 101 in parallel, and then the optical film 400 can be inserted into the cavity 101 in parallel.

[0099] When the optical film 400 is inserted parallel to the cavity 101, the end of the optical film 400 first contacts the elastic cantilever 320. As the optical film 400 continues to be pushed toward the interior of the cavity 101, the optical film 400 is squeezed and deflected relative to the fixed portion 310, accumulating force in the process. When the optical film 400 is pushed until the free end of the elastic cantilever 320 is directly opposite the ear-hanging notch 410, the elastic cantilever 320 loses the external force and, under the action of the elastic reset force, rotates in the opposite direction again until the free end of the elastic cantilever 320 is located within the ear-hanging notch 410. When the optical film 400 is pushed into place, the elastic cantilever 320 can be inserted into the ear-hanging notch 410 under the action of the elastic reset force and is locked in the ear-hanging notch 410.

[0100] It is understood that the angle between the elastic cantilever 320 and the z-direction when inserted into the hook notch 410 of the optical film 400 is approximately equal to the angle between the elastic cantilever 320 and the z-direction in the initial state. In this case, the optical film 400 can be relatively fixed relative to the optical plate 200 under the engaging action of the elastic cantilever 320. Based on this, the specific location of the hook notch 410 on the optical film 400 and the size of the hook notch 410 along the x-direction can be designed so that after the optical film 400 is pushed into the preset position, the elastic cantilever 320 can be precisely engaged within the hook notch 410. Furthermore, the angle between the elastic cantilever 320 and the x-direction in the initial state and when engaged with the hook notch 410 is approximately the same. This ensures that after assembly, the elastic cantilever 320 will not push the optical film 400 due to the accumulated force, causing the optical film 400 to shift and affect the display effect.

[0101] In some embodiments, as Figure 14 As shown, when the optical film 400 is secured using the elastic cantilever 320, the optical film 400 can be placed on the optical plate 200, enabling the optical plate 200 to support the optical film 400. In this case, along the x-direction, the free end of the elastic cantilever 320 is located between the optical plate 200 and the side plate 120. Furthermore, the orthographic projection of the elastic cantilever 320 on a first plane, which is perpendicular to the x-direction, partially overlaps with the orthographic projection on the optical plate 200. In other words, the free end of the elastic cantilever 320 can extend below the surface of the optical plate 200 facing the optical film 400.

[0102] Because the end of the optical film 400 facing the side panel 120 protrudes beyond the end of the optical plate 200 facing the side panel 120, when the free end of the elastic cantilever 320 is positioned between the optical plate 200 and the side panel 120, it is easier for the optical film 400 to squeeze the elastic cantilever 320, causing the elastic cantilever 320 to deform. In addition, when the free end of the elastic cantilever 320 extends below the side surface of the optical plate 200 facing the optical film 400, it ensures that the elastic cantilever 320 is completely inserted into the ear-hanging notch 410 of the bottommost optical film 400. This increases the contact area between the elastic cantilever 320 and the ear-hanging notch 410, thereby enhancing the snap-fit effect between the two.

[0103] In some embodiments, reference Figure 15To facilitate horizontal insertion of the optical film 400 into the cavity 101, a guide structure 800 is provided on the side of the optical plate 200 facing the optical film 400. The guide structure 800 has a guide surface 810 on the side facing away from the optical plate 200. The distance between the guide surface 810 and the optical plate 200 along the z-direction gradually increases from the opening of the cavity 101 to the side panel 120. For example, the guide structure 800 may be a trapezoidal structure, with the inclined surface of the trapezoid facing the support plate 130.

[0104] When the optical film 400 is pushed horizontally into the cavity 101, the guide surface 810 can guide the optical film 400, making it easier for the optical film 400 to squeeze the elastic cantilever 320, thereby improving assembly efficiency. After the optical film 400 is pushed into place, the bottom of the optical film 400 at the bottom layer abuts against the guide structure 800, and the elastic cantilever 320 is engaged with the ear notch 410 of the optical film 400, so that the guide structure 800 and the elastic cantilever 320 cooperate to fix the optical film 400.

[0105] In this embodiment, the orthographic projection of the elastic cantilever 320 on the first plane partially overlaps with the orthographic projection of the guide structure 800 on the first plane. It can also be understood that the free end of the elastic cantilever 320 extends to the side of the guide structure 800 facing the side panel 120, so as to ensure that the elastic cantilever 320 can be completely passed through and clamped in the ear-hanging notch 410 of the optical film 400 located at the bottom layer.

[0106] Furthermore, the guide structure 800 can be fixed to the optical plate 200 by bonding, thereby ensuring a stable connection between the guide structure 800 and the optical plate 200, and avoiding pushing the guide structure 800 to move together during the process of pushing the optical film 400, thereby affecting the assembly effect.

[0107] In some embodiments, reference Figure 16 The fixing portion 310 is fixedly connected to the optical plate 200, and the elastic cantilever 320 is connected to the fixing portion 310. The elastic cantilever 320 is inserted into and engaged with the ear-hanging notch 410 of the optical film 400. At this time, the optical film 400 and the elastic cantilever 320 are relatively fixed. Since the elastic cantilever 320 is fixed to the optical plate 200, the optical film 400 and the optical plate 200 can be relatively fixed.

[0108] When assembling the display device in this embodiment, the connecting bracket 300 can be first fixed to the optical plate 200, and then the optical plate 200 is horizontally inserted into the cavity 101, and then the optical film 400 is horizontally inserted into the cavity 101 to complete the assembly.

[0109] Furthermore, in this embodiment, the elastic cantilever 320 is positioned between the optical plate 200 and the support plate 130. Along the z-direction, the free end of the elastic cantilever 320 extends toward the support plate 130. Furthermore, along the x-direction, the free end of the elastic cantilever 320 extends toward the side plate 120, creating a predetermined angle between the elastic cantilever 320 and the z-direction. This design facilitates the deformation of the elastic cantilever 320 when the optical film 400 is horizontally inserted into the cavity 101, thereby facilitating assembly of the optical film 400.

[0110] In some embodiments, reference is made to Figure 16 and Figure 17 In this embodiment, the fixing portion 310 may include a first fixing plate 311, which is located on the side of the optical plate 200 facing the support plate 130. The elastic cantilever 320 is connected to one end of the first fixing plate 311. The optical plate 200 is provided with a third adhesive layer 901, and the first fixing plate 311 can be bonded to the third adhesive layer 901, thereby fixing the first fixing portion 310 to the optical plate 200. This prevents the optical film 400 from pushing the connecting bracket 300 to move when the optical film 400 is pushed in, thereby affecting the assembly effect.

[0111] In some embodiments, reference is made to Figure 18 and Figure 19 The fixing portion 310 may include a first fixing plate 311 and a second fixing plate 312. The second fixing plate 312 is connected to one end of the first fixing plate 311, and the elastic cantilever 320 is connected to the other end of the first fixing plate 311. Specifically, the first fixing plate 311 is located on the side of the optical plate 200 facing the support plate 130 and is bonded to the optical plate 200 via a third adhesive layer 901 provided on the optical plate 200. The second fixing plate 312 is located on the side of the optical plate 200 facing the side plate 120. A fourth adhesive layer 902 is provided on the side of the optical plate 200 facing the side plate 120, and the second fixing plate 312 is bonded to the fourth adhesive layer 902. By bonding both the first fixing plate 311 and the second fixing plate 312 to the optical plate 200, the bonding area between the fixing portion 310 and the optical plate 200 can be increased, thereby improving the fixing effect between the fixing portion 310 and the optical plate 200.

[0112] In some embodiments, reference is made to Figure 20 and Figure 21The fixing portion 310 may include a first fixing plate 311, a second fixing plate 312, and a third fixing plate 313, wherein the second fixing plate 312 is connected to one end of the first fixing plate 311, the elastic cantilever 320 is connected to the other end of the first fixing plate 311, and the third fixing plate 313 is connected to the end of the second fixing plate 312 away from the first fixing plate 311. When the fixing portion 310 is fixedly connected to the optical plate 200, the first fixing plate 311 is located on the side of the optical plate 200 facing the support plate 130 and is bonded to the optical plate 200 via the third adhesive layer 901 provided on the optical plate 200. The second fixing plate 312 is located on the side of the optical plate 200 facing the side plate 120 and is bonded to the optical plate 200 via the fourth adhesive layer 902 provided on the optical plate 200. The third fixing plate 313 is located on the side of the optical plate 200 facing the base plate 110. The fifth adhesive layer 905 is provided on the side of the optical plate 200 facing the base plate 110, and the third fixing plate 313 is bonded to the fifth adhesive layer 905. Thus, all three fixing plates are bonded to the optical plate 200, further increasing the bonding area with the optical plate 200 and thus further improving the fixing effect between the fixing portion 310 and the optical plate 200.

[0113] As an optional embodiment, the connecting bracket 300, the fixing portion 310, and the elastic cantilever 320 mentioned in the aforementioned embodiments can be an integrated structure to improve the overall structural strength of the connecting bracket 300. Furthermore, the connecting bracket 300 can also be made of metal, which can also ensure that the elastic cantilever 320 has good deformation ability, preventing the elastic cantilever 320 from breaking during the assembly of the optical film 10, thereby facilitating assembly of the display device.

[0114] In addition, it is worth noting that the cavity 101 in each of the aforementioned embodiments can be regarded as a module back plate 100 formed in one piece. Figure 22 The display device in this embodiment further includes a middle frame 1000, which is connected to the side panels 120. A portion of the middle frame 1000 extends toward the interior of the back panel 100, thereby forming a U-shaped cavity 101 with the back panel 100. In other words, in this embodiment, the support plate 130 and the middle frame 1000 are an integrated structure, thereby increasing the applicability of the display device of the present invention.
