[0005] According to an embodiment of the present invention, the display device further includes a fastener, the adapter includes a connecting portion and a cantilever portion, the connecting portion is connected to the side surface, and the fastener locks the cantilever portion and the middle frame assembly.

[0006] According to an embodiment of the present invention, the cantilever portion extends toward the display panel, and an accommodating gap is formed between the cantilever portion and the cover plate.

[0007] According to an embodiment of the present invention, the cantilever portion is disposed at an edge of the connecting portion away from the display panel, and the cantilever portion is folded toward the middle frame assembly relative to the connecting portion and is located outside the middle frame assembly.

[0008] According to one embodiment of the present invention, the display device also includes a backlight assembly, which is connected to the middle frame assembly, the middle frame assembly has a first extension portion located inside the cantilever portion, the backlight assembly has a second extension portion located inside the first extension portion, and the fastener locks the cantilever portion, the first extension portion and the second extension portion.

[0046] The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention, but cannot be used to limit the scope of the present invention, that is, the present invention is not limited to the described embodiments.

[0047] In the description of the present invention, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate positions or positional relationships only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. "Vertical" is not strictly vertical, but is within the allowable error range. "Parallel" is not strictly parallel, but is within the allowable error range.

[0048] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0049] After noticing that the cover plate of the existing display device has structural damage such as cracks or deformation, the applicant studied and analyzed the various structures of the display device. The applicant found that in the non-display area of ​​the existing display device, the cover plate is bonded to the middle frame assembly by adhesive. Since the portion of the cover plate located in the non-display area is all bonded to the middle frame assembly, when the portion of the cover plate corresponding to the non-display area is uneven, the concave portion toward the middle frame assembly will bear compressive stress, and the convex portion protruding away from the middle frame assembly will bear tensile stress, so that there will be uneven force in the uneven area, which will lead to cracks or deformation in some areas of the cover plate due to stress concentration. After further research and analysis, the applicant found that since the edge areas of the cover plate located in the non-display area are bonded to the middle frame assembly, the edge areas of the cover plate have a large bonding area, and when subjected to stress, it is not easy to buffer or release internal stress, resulting in cracks or deformation problems.

[0050] Based on the above problems found by the applicant, the applicant has improved the structure of the display device. The embodiments of the present invention are further described below.

[0051] In order to better understand the present invention, Figures 1 to 12 Embodiments of the present invention are described.

[0052] Figure 1 The front structure of a display device 1 according to an embodiment is schematically shown. Figure 1 As shown, the display device 1 of the embodiment of the present invention comprises a display area 1a and a non-display area 1b located around the display area 1a. The display area 1a is used to display visual images and can also be used as a user touch control area.

[0053] Figure 2 Schematically shows Figure 1The exploded structure of the display device 1 of the illustrated embodiment. The display device 1 of the embodiment of the present invention includes a cover body 10, a display panel 20, a middle frame assembly 30 and a backlight assembly 50. A storage space is formed between the cover body 10 and the middle frame assembly 30. The storage space is used to accommodate the display panel 20. The display panel 20 corresponds to the display area 1a and is used to display a visual image or perform touch control. The backlight assembly 50 is used to provide a light source for the display panel 20. The display panel 20 of this embodiment may include a touch control layer, a color film substrate, a liquid crystal layer and an array substrate. In some other embodiments, the display device 1 may not be provided with a backlight assembly 50, and the display device 1 adopts a self-luminous unit form so that the display panel 20 displays a visual image. The way in which the display panel 20 displays images and the selection of light sources are not limited here.

[0054] Figure 3 Schematically shows Figure 1 The cross-sectional structure of the display device 1 of the embodiment shown is along the AA direction. Figure 3 As shown, along the thickness direction X, the cover 10, the display panel 20 (not shown in the figure), the middle frame assembly 30 (not shown in the figure) and the backlight assembly 50 are stacked. The backlight assembly 50 is located on one side of the cover 10. The cover 10 is connected to the middle frame assembly 30, and the backlight assembly 50 is connected to the middle frame assembly 30. The middle frame assembly 30 can provide support for the backlight assembly 50 and the cover 10.

[0055] Figure 4 Schematically shows Figure 3 Enlarged view of point B in the middle. Figure 4 As shown, the cover body 10 includes a cover plate 11 and an adapter 12. The cover plate 11 has a side surface 11a facing the middle frame assembly 30 and corresponding to the non-display area 1b. The adapter 12 is arranged on the side surface 11a. The display panel 20 and the adapter 12 are located on the same side of the cover plate 11. The middle frame assembly 30 is connected to the cover plate 11 through the adapter 12. In one example, the cover plate 11 is a transparent structure, and the material of the cover plate 11 can be glass or plastic.

[0056] Figure 5 The structure of the cover 10 of an embodiment is schematically shown. Figure 5 As shown, more than two adapters 12 are arranged at intervals along the circumference of the display area 1a. In this embodiment, the cover plate 11 has a frame 111 corresponding to the non-display area 1b. In one example, the cover plate 11 includes four frames 111. A group of frames 111 is formed relative to the two frames 111. Adapters 12 are arranged on the two groups of frames 111. It can be understood that in some other embodiments, the adapter 12 can be arranged on only one group of frames 111.

[0057] In the display device 1 of the embodiment of the present invention, more than two adapters 12 are arranged on the cover plate 11, and the middle frame assembly 30 is connected to the cover body 10 through the adapters 12. Since the adapters 12 are arranged at intervals, after the cover plate 11 and the middle frame assembly 30 are connected, the area between two adjacent adapters 12 on the cover plate 11 is not easily constrained by the middle frame assembly 30, so that even if the area between two adjacent adapters 12 on the cover plate 11 is subjected to uneven stress, the internal stress of the cover plate 11 will be buffered or released, which is conducive to reducing the possibility of cracks or deformation of the cover plate 11 due to the inability to buffer or release the internal stress of the cover plate 11 due to full adhesion with the middle frame assembly 30, and also makes it difficult for the adapter 12 to separate and fall off from the middle frame assembly 30 due to the long-term action of the internal stress of the cover plate 11, thereby helping to extend the service life of the display device 1, improve the structural integrity of the cover plate 11 during long-term use, and reduce the maintenance loss cost. In addition, the adapter 12 can occupy a smaller area on the cover plate 11, thereby reducing the area of ​​the silk-screen ink of the portion of the cover plate 11 corresponding to the non-display area 1b, and further reducing the area of ​​the portion of the cover plate 11 corresponding to the non-display area 1b, so that the display device 1 can achieve a narrow frame or full-screen display effect. Furthermore, since the middle frame assembly 30 and the adapter 12 are easy to disassemble and assemble, the middle frame assembly 30 and the adapter 12 can be easily separated during the later maintenance or repair process, reducing the difficulty of maintenance and improving the maintenance friendliness.

[0058] In one embodiment, see Figure 4 As shown, the adapter 12 and the cover plate 11 are bonded and connected. The use of bonding can reduce the complexity of the structural design of the cover plate 11 and the adapter 12, which is conducive to simplifying the processing procedures of the cover plate 11 and the adapter 12, thereby reducing the processing difficulty of the cover plate 11 and the adapter 12. In addition, the use of bonding can reduce the difficulty of the connection operation and reduce the possibility of the adapter 12 scratching the screen printing ink on the cover plate 11 during the connection process. In one example, an adhesive is applied to the cover plate 11 or an adhesive tape is pasted, and then the adapter 12 is attached to the adhesive or adhesive tape to complete the connection and fixation of the adapter 12 and the cover plate 11. In one example, the adapter 12 can be a rectangular structure. The length of the adapter 12 can be 14mm to 30mm, and the width can be 6mm to 15mm. The thickness of the adhesive layer formed by the adhesive or adhesive tape is 0.15mm to 0.35mm.

[0059] In one embodiment, the material of the adapter 12 may be aluminum or aluminum alloy, so that the adapter 12 has good strength while remaining lightweight, and the adapter 12 has good processability. In some other embodiments, the material of the adapter 12 may also be plastic.

[0060] In one embodiment, see Figure 4 As shown, the display device 1 further includes a flexible sealing pad 60. A flexible sealing pad 60 is provided between the middle frame assembly 30 and the portion of the cover plate 11 corresponding to the non-display area 1b. The flexible sealing pad 60 has compressibility and good resilience. The flexible sealing pad 60 can isolate the middle frame assembly 30 and the cover plate 11, reduce the possibility of the middle frame assembly 30 scratching the screen printing ink of the cover plate 11 when assembling the middle frame assembly 30 and the cover body 10, and also help to reduce the external dust or water vapor and other substances from entering the interior of the display device 1 from between the middle frame assembly 30 and the cover plate 11. In one example, the flexible sealing pad 60 can be a buffer foam.

[0061] In one embodiment, see Figure 4 As shown, there is a receiving gap 100 between the middle frame assembly 30 and the cover plate 11. In an embodiment where the adapter 12 and the cover plate 11 are bonded and connected using adhesive, the receiving gap 100 can be used to receive the adhesive overflowing from between the adapter 12 and the cover plate 11, thereby reducing the possibility that the adhesive contacts the middle frame assembly 30 and bonds the middle frame assembly 30, making it difficult to disassemble the middle frame assembly 30. In one example, the receiving gap 100 is an annular space surrounding the adapter 12.

[0062] In one embodiment, see Figure 4As shown, the display device 1 also includes a fastener 40. The fastener 40 locks the adapter 12 and the middle frame assembly 30. After the cover body 10 and the middle frame assembly 30 are assembled, the fastener 40 can be used to lock the adapter 12 and the middle frame assembly 30 to improve the connection stability and reliability of the cover body 10 and the middle frame assembly 30. In one example, the fastener 40 and the adapter 12 are locked by a threaded connection, so that when the middle frame assembly 30 and the cover body 10 need to be separated or locked, it is convenient to disassemble and assemble the fastener 40. In one example, the middle frame assembly 30 has a recess extending along the thickness direction X and a mounting hole connected to the recess. At least part of the adapter 12 is located in the recess. The adapter 12 has a threaded hole corresponding to the mounting hole. The fastener 40 can be a stepped screw, wherein a section with a smaller diameter is a threaded section. The fastener 40 passes through the mounting hole and is threadedly connected to the threaded hole of the adapter 12. In the thickness direction X, an adjustment gap is reserved between the nut of the fastener 40 and the middle frame assembly 30, so that the cover body 10 has a movable amount along the thickness direction X, reducing the possibility of the cover 11 falling off due to the adhesive layer between the adapter 12 and the cover plate 11 and the silk-screen ink on the cover plate 11 being in a tensile state for a long time after the fastener 40 is locked, resulting in the peeling of the silk-screen ink, the separation of the adhesive layer from the cover plate 11, or the separation of the adhesive layer from the adapter 12. In one example, the material of the adapter 12 can be aluminum or an aluminum alloy. Alternatively, the adapter 12 includes a plastic body and a nut embedded in the plastic body. The fastener 40 is threadedly connected to the nut. In another example, the fastener 40 and the adapter 12 can be locked by a snap-fit ​​connection. The fastener 40 has a snap-fit ​​structure, and the adapter 12 has a slot. The buckle of the fastener 40 can be snapped into the slot of the adapter 12 , so as to achieve the connection and fixation between the fastener 40 and the adapter 12 , and then the fastener 40 locks the adapter 12 and the middle frame assembly 30 .

[0063] Figure 6 The front structure of a display device 1 according to another embodiment of the present invention is schematically shown. Figure 7 Schematically shows Figure 6 Cross-sectional structure along CC direction. Figure 8 Schematically shows Figure 7 Enlarged view of point D in the middle.

[0064] In one embodiment, see Figure 8 As shown, in this embodiment Figure 1The same structures as those in the illustrated embodiments will not be described in detail, and please refer to the above embodiments. The differences are mainly described in this embodiment. The adapter 12 of this embodiment includes a connecting portion 121 and a cantilever portion 122. The connecting portion 121 and the cantilever portion 122 are connected to each other. The adapter 12 is connected to the side surface 11a of the cover plate 11 through the connecting portion 121. The fastener 40 locks the cantilever portion 122 and the middle frame assembly 30. In one example, the connecting portion 121 and the cantilever portion 122 are an integrally molded structure. The adapter 12 can more flexibly select different positions of the middle frame assembly 30 through the cantilever portion 122 to achieve connection, thereby improving the flexibility of the connection position selection and the flexibility of the connection position structure design between the middle frame assembly 30 and the adapter 12, and is also conducive to optimizing the internal space utilization of the display device 1 and ensuring the compactness of the overall structure.

[0065] Continue to see Figure 8 As shown, the cantilever portion 122 is disposed at the edge of the connecting portion 121 close to the display panel 20. The cantilever portion 122 extends from the connecting portion 121 toward the display panel 20. A receiving gap 100 is formed between the cantilever portion 122 and the cover plate 11. In an embodiment in which the adapter 12 and the cover plate 11 are bonded and connected using an adhesive, the receiving gap 100 can be used to accommodate the adhesive overflowing from between the adapter 12 and the cover plate 11, thereby reducing the possibility that the adhesive contacts the middle frame assembly 30 or the fastener 40 and sticks to the middle frame assembly 30 or the fastener 40, thereby making the middle frame assembly 30 or the fastener 40 difficult to disassemble. In addition, the receiving gap 100 can avoid the display panel 20, so that while improving the compactness of the internal structure of the display device 1, the adapter 12 is not likely to interfere with the display panel 20. In one example, there is a gap between the edge area of ​​the cantilever portion 122 away from the connecting portion 121 and the middle frame assembly 30 to avoid positional interference between the cantilever portion 122 of the adapter 12 and the middle frame assembly 30. In one example, the connecting portion 121 is a rectangular structure, and the cantilever portion 122 is also a rectangular structure.

[0066] In one embodiment, see Figure 8 As shown, in the thickness direction X, there is a gap 200 between the adapter 12 and the middle frame assembly 30, so that the cover body 10 has a movable amount along the thickness direction X, thereby reducing the possibility of the cover plate 11 falling off due to the adhesive layer between the adapter 12 and the cover plate 11 and the silk-screen ink on the cover plate 11 being in a tensile state for a long time after the fastener 40 is locked, resulting in the silk-screen ink peeling off, the adhesive layer and the cover plate 11 separating, or the adhesive layer and the adapter 12 separating.

[0067] In one embodiment, see Figure 8As shown, the adapter 12 has a limiting groove 300 extending along the thickness direction X. The limiting groove 300 has an opening on the surface of the adapter 12 facing away from the cover plate 11. The middle frame assembly 30 has a limiting convex portion 400 extending and protruding along the thickness direction X. The limiting convex portion 400 is plugged into the limiting groove 300. When assembling the cover body 10 and the middle frame assembly 30, the limiting convex portion 400 can be plugged into the limiting groove 300 to complete the positioning and limiting of the middle frame assembly 30, so as to ensure that the middle frame assembly 30 is quickly and accurately positioned at a predetermined position, and then the fastener 40 is used to lock the middle frame assembly 30 and the cantilever portion 122. In one example, the limiting groove 300 is correspondingly arranged on the connecting portion 121 of the adapter 12. In another example, the adapter 12 has a limiting protrusion 400 , and the middle frame assembly 30 has a limiting groove 300 , and the positioning and limiting of the middle frame assembly 30 can also be achieved by the limiting protrusion 400 and the limiting groove 300 .

[0068] In one embodiment, see Figure 8 As shown, the edge of the backlight assembly 50 is snap-fitted with the middle frame assembly 30. The edge of the backlight assembly 50 has a through hole, and the middle frame assembly 30 is also provided with a mounting hole connected to the through hole. A threaded hole is provided on the cantilever portion 122 corresponding to the through hole of the middle frame assembly 30. The rod of the fastener 40 passes through the through hole and the mounting hole and is then threadedly connected to the threaded hole. The cap end of the fastener 40 overlaps the edge of the backlight assembly 50. The fastener 40 locks the backlight assembly 50, the middle frame assembly 30 and the cantilever portion 122.

[0069] Fig. 9 The front structure of a display device 1 according to another embodiment of the present invention is schematically shown. Fig.10 Schematically shows Fig. 9 The exploded structure of the display device 1 of the illustrated embodiment. Fig.11 Schematically shows Fig. 9 Cross-sectional structure along EE direction. Fig.12 Schematically shows Fig.11 Enlarged view of point F in the middle.

[0070] In one embodiment, see Fig. 9 and Fig.10 As shown, in this embodiment Figure 8 The same structures as those in the illustrated embodiment will not be described in detail. This embodiment mainly describes the differences. The display device 1 of this embodiment further includes two outer frame assemblies 70 arranged opposite to each other. The two outer frame assemblies 70 are independently arranged from the middle frame assembly 30 and are used in conjunction with the middle frame assembly 30.

[0071] See also Fig.11 and Fig.12As shown, the adapter 12 of this embodiment includes a connecting portion 121 and a cantilever portion 122. The cantilever portion 122 is disposed at the edge of the connecting portion 121 away from the display panel 20. The cantilever portion 122 is folded toward the middle frame assembly 30 relative to the connecting portion 121 and is located on the outside of the middle frame assembly 30. The outside of the middle frame assembly 30 refers to the side of the middle frame assembly 30 away from the central area of ​​the display device 1. The cantilever portion 122 can limit the middle frame assembly 30 on the outside of the middle frame assembly 30. The adapter 12 of this embodiment can be disposed at a position close to the edge of the cover plate 11 itself. The surface of the cantilever portion 122 away from the middle frame assembly 30 can be flush with the narrow surface of the cover plate 11. The narrow surface of the cover plate 11 is adjacent to the side surface 11a. In this way, the adapter 12 occupies an area on the cover plate 11 that is closer to the edge, so that the width of the silk-screen ink can be further reduced to increase the area of ​​the display area 1a. In one example, see Fig.12 As shown, the cross section of the adapter 12 may be L-shaped. The outer frame assembly 70 is located outside the cantilever portion 122, and a flexible sealing pad 60 is provided between the outer frame assembly 70 and the cover plate 11, which is conducive to reducing the entry of dust or water vapor and other substances from the outer frame assembly 70 and the cover plate 11 into the display device 1. In one example, the outer frame assembly 70 overlaps the narrow surface of the cover plate 11. The flexible sealing pad 60 is located between the narrow surface of the cover plate 11 and the outer frame assembly 70.

[0072] In one embodiment, continue to see Fig.12 As shown, the middle frame assembly 30 has a first extension portion 31 located inside the cantilever portion 122. The backlight assembly 50 has a second extension portion 51 located inside the first extension portion 31. At least part of the first extension portion 31 is located between the cantilever portion 122 and the second extension portion 51. The fastener 40 locks the cantilever portion 122, the first extension portion 31 and the second extension portion 51. In one example, the cantilever portion 122 and the first extension portion 31 have through holes, and the second extension portion 51 is provided with threaded holes corresponding to the through holes. The rod of the fastener 40 passes through the through holes of the cantilever portion 122 and the first extension portion 31 and is threadedly connected with the threaded hole. In another example, a through hole is also provided on the outer frame assembly 70, and the fastener 40 passes through the through holes of the outer frame assembly 70, the cantilever portion 122 and the first extension portion 31 and is threadedly connected with the threaded hole of the second extension portion 51, so that the fastener 40 locks the outer frame assembly 70, the cantilever portion 122, the first extension portion 31 and the second extension portion 51. In one example, the through hole on the cantilever portion 122 is a waist-shaped hole, so that the position error can be compensated, the difficulty of aligning the through hole on the cantilever portion 122 and the through hole on the middle frame assembly 30 with each other and the position accuracy requirement can be reduced, and the fastener 40 can smoothly pass through the through hole on the cantilever portion 122. In one example, the cross section of the middle frame assembly 30 can be L-shaped. A buffer foam is arranged between the middle frame assembly 30 and the display panel 20, which is conducive to preventing dust or water vapor from entering between the display panel 20 and the backlight assembly 50.

[0073] The display device 1 of the embodiment of the present invention is provided with two or more adapters 12 on the cover plate 11, so that the middle frame assembly 30 can be connected to the cover body 10 through the adapters 12. The two or more adapters 12 are provided in the edge area of ​​the cover plate 11 beyond the display panel 20 and are arranged at intervals along the circumference of the display panel 20. The cover plate 11 and the middle frame assembly 30 are connected and fixed by the two or more adapters 12, thereby reducing the connection area between the portion of the cover plate 11 corresponding to the non-display area 1b and the middle frame assembly 30, and reducing the constraint effect of the portion of the cover plate 11 corresponding to the non-display area 1b on the middle frame assembly 30. In this way, on the one hand, when there is uneven force on the portion of the cover plate 11 corresponding to the non-display area 1b, since the portion of the cover plate 11 located between the two adapters 12 is not constrained, the internal stress of the portion of the cover plate 11 corresponding to the non-display area 1b can be buffered or released through the unconstrained portion, thereby reducing the problem of cracks or deformation of the cover plate 11; on the other hand, when there is unevenness on the portion of the cover plate 11 located between the two adapters 12, the concave and convex portions are not constrained, so that it is not easy to have excessive internal stress concentration, thereby reducing the problem of cracks or deformation of the cover plate 11.

[0074] The embodiment of the present invention further provides a method for manufacturing a display device 1, which comprises:

[0075] The display panel 20 and the cover plate 11 are attached and connected;

[0076] Along the circumference of the display panel 20, more than two adapters 12 are spaced apart on the cover plate 11 beyond the edge region of the display panel 20, and the adapters 12 and the display panel 20 are located on the same side of the cover plate 11;

[0077] The middle frame assembly 30 is connected to the adapter 12 .

[0078] In one embodiment, more than two adapters 12 are arranged on the cover plate 11 along the circumference of the display panel 20 and beyond the edge area of ​​the display panel 20. In the step where the adapter 12 and the display panel 20 are located on the same side of the cover plate 11, the adapter 12 is bonded to the edge area.
