[0040] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0041] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0042] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0043] Figure 1 A schematic diagram of a display device provided in the related art. Figure 1 As shown, the display device includes a display panel 110 and a backlight module, and the backlight module includes a back plate and a reflective sheet, a diffuser plate and an optical film stacked in sequence on the back plate, the back plate includes a bottom plate and a side plate 1212 around the bottom plate, and a bend is set at one end of the side plate 1212 away from the bottom plate, and the bend includes a first folded edge 01, a second folded edge 02 and a third folded edge 03 fixedly connected in sequence, thus forming a "C"-shaped bend, and the reflective sheet 1221, the diffuser plate 1222 and the optical film 1223 are all located inside the "C"-shaped bend.

[0044] The display panel 110 is attached to the upper surface of the third folded edge 03 by means of the foam tape 31, in order to ensure the subjective display effect and prevent the optical film 1223 from directly contacting the display panel 110 and causing abrasion between the two. Figure 1 When the display device shown is assembled, a seal 32 is added between the third fold 03 and the optical film 1223 inside the "C"-shaped bend, so that the seal 32 is used to maintain the distance between the optical film 1223 and the display panel 110. It should be noted that in the display device of the related art, the back plate also has other shapes of bends, such as "F"-shaped bends. Figure 1 The structure shown in the figure is supplemented with a middle frame as the exterior, but its overall assembly scheme is different from Figure 1 The principle of the assembly scheme is the same as that of Figure 1The display device shown is understood for the sake of simplicity and will not be shown or described in detail here.

[0045] Combination Figure 1 , Figure 2 A schematic diagram of another display device provided in the related art. Figure 2 As shown, in Figure 1 On the basis of the display device, a middle frame 33 and double-sided tape 34 are further added. The double-sided tape 34 can be a very high strength adhesive (VHB) tape. The middle frame 33 is fixed to the upper surface of the third folded edge 03 of the back plate by the double-sided tape 34, and the display panel 110 is adhered to the upper surface of the middle frame 33 for bearing by the foam tape 31, so as to lock the display panel 110 through the middle frame 33 and serve as the appearance of the display panel 110.

[0046] However, Figure 1 and Figure 2 When the display device shown is assembled or packaged, it is often necessary to use several of the middle frame 33, foam tape 31, double-sided tape 34 and seal 32 to fix the display panel 110 to one side of the back plate, resulting in a complex overall structure and the use of more assembly parts, thereby reducing assembly efficiency and increasing assembly costs, which is not conducive to large-scale applications.

[0047] In order to solve the above technical problems, the embodiment of the present application provides a display device, which includes: a display panel and a backlight module; the display panel includes a display area and a non-display area at least partially surrounding the display area; the backlight module includes: a back plate, including a bottom plate and a side plate located at the periphery of the bottom plate and fixed to the peripheral edge of the bottom plate to form a receiving groove, and a bend is set at one end of the side plate away from the bottom plate, and the bend includes a first folded edge, a second folded edge and a third folded edge that are fixedly connected in sequence; an optical device is fixedly overlapped with the first folded edge and is located between the display panel and the first folded edge; the display panel is located in the receiving groove, and in a direction perpendicular to the plane where the bottom plate is located, the third folded edge overlaps with the non-display area of ​​the display panel. Thus, the display panel is positioned and fixed by using the back plate in the backlight module, fewer assembly parts are used, the overall structure is simple, the assembly efficiency is improved, and the assembly cost is reduced.

[0048] The display device provided in the embodiments of the present application is exemplarily described below with reference to the accompanying drawings.

[0049] Figure 3 This is a schematic diagram of the structure of a display device provided in an embodiment of the present application. Figure 3 As shown, the display device includes: a display panel 110 and a backlight module 120 .

[0050] The backlight module 120 is a direct-type backlight module, which is used to fix and accommodate the display panel 110. Specifically, the backlight module 120 provides backlight to the display panel 110 to illuminate the display panel 110. The display panel changes its transmittance under the action of voltage, thereby realizing imaging. The display panel 110 can adopt any shape of liquid crystal panel known to those skilled in the art, such as a rectangular liquid crystal panel or a square liquid crystal panel, which is not limited here.

[0051] Figure 4 A schematic diagram of the structure of a display panel provided in an embodiment of the present application. Figure 3 Based on Figure 4 , wherein the display panel 110 includes a display area 111 located in the middle of the display panel 110 and a non-display area 112 located around the display area 111 .

[0052] Specifically, the display area 111 includes red, green and blue sub-pixels, and the three-color sub-pixels constitute a pixel unit for array arrangement. The display panel further forms a color image by utilizing the display area 111 to simultaneously display and combine the three colors of red, green and blue; conversely, the non-display area 112 does not have an image display function, which is equivalent to the peripheral black border of the display panel 110.

[0053] In addition, the non-display area 112 may also partially surround the display area 111. For example, the non-display area 112 may be located to the left and above the display area 111, or to the right and above the display area 111, or to the left, above and to the right of the display area 111, or to the left, below and to the right of the display area 111, which is not limited here.

[0054] Figure 5 A schematic diagram of the structure of a backlight module provided in an embodiment of the present application is shown in FIG. Figure 6 This is a schematic diagram of the structure of a backplane provided in an embodiment of the present application. Figure 5 and Figure 6 As shown, the backlight module includes: a back panel 121 and an optical device 122 .

[0055] Among them, Figure 6 As shown, the back panel 121 includes a bottom panel 1211 and a side panel 1212. The side panel 1212 is located at the periphery of the bottom panel 1211 and fixed to the peripheral edge of the bottom panel 1211. At the same time, the side panel 1212 is inclined at a preset angle relative to the bottom panel 1211 to further form a receiving groove for accommodating the display panel by utilizing the bottom panel 1211 and the inclined side panel 1212.

[0056] A bend is provided at one end of the side panel 1212 away from the bottom panel 1211, and the bend includes a first folded edge 01, a second folded edge 02 and a third folded edge 03. The first folded edge 01, the second folded edge 02 and the third folded edge 03 are fixedly connected in sequence, and the second folded edge 02 is respectively perpendicular to the bottom panel 1211, the first folded edge 01 and the third folded edge 03, thus forming a "C"-shaped bend, and a receiving groove for accommodating the display panel is formed by the bottom panel 1211 and the side panel 1212 including the bend.

[0057] like Figure 6 As shown, in the direction perpendicular to the plane where the bottom plate 1211 is located, the first folded edge 01 and the third folded edge 03 completely overlap, that is, the overlapping area is 100%, forming the first folded edge 01 and the third folded edge 03 that are flush arranged; in addition, the first folded edge 01 and the third folded edge 03 may also partially overlap, and the overlapping area may be 50%, 70% or other sizes, which can be set according to the actual design requirements of the back plate 121 to accommodate the display panel 110, and is not limited here.

[0058] like Figure 5 As shown, along the direction perpendicular to the plane where the bottom plate 1211 is located, the first folded edge 01 is higher than the bottom plate 1211 and close to the peripheral edge of the bottom plate 1211, so that the optical device 122 is fixedly overlapped on the first folded edge 01 in the embodiment of the application.

[0059] exist Figure 5 On the basis of Figure 7 This is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Figure 7 As shown, the optical device 122 is located between the display panel 110 and the first folded edge 01. Specifically, the optical device 122 provides backlight and redistributes the light incident on the display panel 110, such as reflecting and diffusing the light, and then irradiates the redistributed light to the display panel 110 to achieve imaging.

[0060] The display panel 110 is located in the receiving groove formed by the back plate 121, that is, the display panel 110 is located between the third folded edge 03 and the optical device 122, and in the direction perpendicular to the plane where the bottom plate 1211 is located, the third folded edge 03 overlaps with the non-display area of ​​the display panel 110 to shield the non-display area. Compared with the assembly solution in the related art that requires the addition of components such as a middle frame to provide a front appearance, the embodiment of the present application utilizes the third folded edge 03 of the back plate 121 as the front appearance, while also being able to better position the display panel, which is conducive to simplifying the overall structure and assembly process of the display device. It can be understood that the display panel 110 shown in the figure is a multi-layer structure, for example, it may include structures such as an array substrate, a facing substrate, and a protective cover plate, which are not limited here.

[0061] In some embodiments, Figure 8This is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Figure 8 As shown, the display device further includes: a supporting structure 130 .

[0062] The support structure 130 is used to support the structure or device located on its upper surface. Specifically, the support structure 130 is located between the display panel 110 and the optical device 122, so that the display panel 110 and the optical device 122 can be spaced apart while supporting the display panel 110, providing a necessary gap between the display panel 110 and the optical device 122, and preventing the optical device 122 from directly contacting the display panel 110 and causing abrasion between the two.

[0063] like Figure 8 As shown, the support structure 130 has a first edge 41 in the non-display area of ​​the display panel 110, and the third folded edge 03 has a second edge 51 in the non-display area of ​​the display panel 110. When the third folded edge 03 completely overlaps with the non-display area of ​​the display panel 110, in a direction perpendicular to the plane where the bottom plate 1211 is located, the support structure 130 overlaps with the non-display area of ​​the display panel 110, such as partially overlapping. At this time, the vertical projection positions of the first edge 41 and the second edge 51 in the non-display area of ​​the display panel 110 are different, and the vertical projection of the first edge 41 is located in the non-display area (as marked with a dotted line). The edge of the support structure 130 away from the bottom plate 1211 is flush with the edge of the display panel 110. The size of the partially overlapping area can be set according to the actual support requirements of the support structure 130, and is not limited here.

[0064] For example, Fig. 9 This is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Figure 8 Based on Fig. 9 When the third folded edge 03 completely overlaps with the non-display area of ​​the display panel 110 , the support structure 130 also completely overlaps with the non-display area of ​​the display panel 110 .

[0065] In which, in the direction perpendicular to the plane where the base plate 1211 is located, the first edge 41 and the second edge 51 are at the same position (as marked by the dotted line), and the edge of the support structure 130 away from the base plate 1211 is flush with the edge of the display panel 110, thereby achieving complete overlap of the support structure 130 and the non-display area of ​​the display panel 110.

[0066] Combination Figure 8 and Fig. 9Compared with the assembly scheme of "back plate - double-sided tape - middle frame - foam tape - display panel" in the related art, the embodiment of the present application removes the middle frame and its upper and lower layers of bonding tape (double-sided tape and foam tape) used to support and form the front appearance, and uses an integrally formed back plate 121 to accommodate the display panel 110, and uses a supporting structure 130 to support the display panel 110, thereby replacing the assembly scheme of the related art, achieving the third folded edge 03 serving as the front appearance while positioning the display panel, with a high consistency in appearance, reducing the use of materials, and reducing assembly costs.

[0067] It should be noted that the support structure 130 completely overlaps or partially overlaps with the non-display area of ​​the display panel 110 , thereby ensuring the display effect of the display area of ​​the display panel 110 and avoiding shielding of the display area.

[0068] In some embodiments, Fig.10 This is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Fig.10 As shown, the display device further includes: a protection structure 140 .

[0069] The protective structure 140 at least includes a first protective structure 141, and the first protective structure 141 is located on the surface of the second folded edge 02 facing the inside of the receiving groove. Fig.10 As shown, the protective structure 140 can be integrally provided with the supporting structure 130, that is, the first protective structure 141 can be integrally provided with the supporting structure 130, for example, they can be integrally processed by special-shaped die cutting, extrusion or other special-shaped processing methods, which are not limited here.

[0070] It should be noted that, along a direction perpendicular to the plane where the first folded edge 01 is located, the length of the first protective structure 141 is less than or equal to the length of the second folded edge, so as to protect at least one of the optical device 122 and the display panel 110 .

[0071] like Fig.10 As shown, along the direction perpendicular to the plane where the first folded edge 01 is located, the length of the first protective structure 141 shown in the figure is equal to the sum of the lengths of the optical device 122, the display panel 110 and the supporting structure 130, so as to protect the optical device 122 and the display panel 110, and prevent the optical device 122 and the display panel 110 from contacting the second folded edge 02 and causing damage during the circulation or lifting of the illustrated structure.

[0072] In addition, along the direction perpendicular to the plane where the first folded edge 01 is located, the length of the first protective structure 141 can also be equal to the sum of the lengths of the optical device 122 and the supporting structure 130 to protect the optical device 122, or the length of the first protective structure 141 can also be equal to the sum of the lengths of the display panel 110 and the supporting structure 130 to protect the display panel 110. The specific length of the first protective structure 141 is not limited here.

[0073] exist Fig.10 On the basis of Fig.11 This is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Fig.11 As shown, the protective structure 140 can be separately provided from the supporting structure 130 , that is, the first protective structure 141 can be separately provided from the supporting structure 130 .

[0074] In the direction perpendicular to the plane where the first folded edge 01 is located, Fig.11 It is shown that the length of the first protective structure 141 is equal to the sum of the lengths of the optical device 122, the display panel 110 and the supporting structure 130 to protect the optical device 122 and the display panel 110. Similarly, the length of the first protective structure 141 can also be equal to the sum of the lengths of the optical device 122 and the supporting structure 130, or equal to the sum of the lengths of the display panel 110 and the supporting structure 130, which is not limited here.

[0075] Combination Fig.10 and Fig.11 The third folded edge 03 can be smoothed by back plate grinding or other methods to prevent the third folded edge 03 from scratching the surface of the display panel 110. The specific method of the smoothing process is not limited here.

[0076] In some embodiments, Fig.12 This is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Fig.12 As shown, the protective structure 140 further includes a second protective structure 142 .

[0077] The second protective structure 142 is located on the surface of the third folded edge 03 facing the inside of the receiving groove. It should be noted that, along the direction perpendicular to the plane where the second folded edge 02 is located, the length of the second protective structure 142 is less than or equal to the length of the third folded edge 03, so as to separate the display panel 110 and the third folded edge 03, thereby protecting the display panel 110 and preventing the third folded edge 03 from scratching the display panel 110. The specific length of the second protective structure 142 is not limited here.

[0078] For example, Fig.12As shown, along the direction perpendicular to the plane where the first folded edge 01 is located, the length of the first protective structure 141 is equal to the sum of the lengths of the support structure 130 and the display panel 110, and along the direction perpendicular to the plane where the second folded edge 02 is located, the length of the second protective structure 142 is smaller than the third folded edge 03. On this basis, the first protective structure 141, the second protective structure 142 and the support structure 130 are integrally arranged to surround the corresponding surfaces of the display panel 110, such as the edge of the display panel 110 and the relative surface of the corresponding non-display area.

[0079] This setting enables Fig.12 The structure shown protects the display panel 110 , preventing the display panel 110 from contacting the second folded edge 02 and causing damage, and preventing the display panel 110 from contacting the third folded edge 03 and causing scratches, thereby improving the aesthetics and integrity of the display panel 110 .

[0080] exist Fig.12 On the basis of Fig.13 This is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Fig.13 As shown, similarly, along the direction perpendicular to the plane where the first folded edge 01 is located, the length of the first protective structure 141 is equal to the sum of the lengths of the support structure 130 and the display panel 110, and along the direction perpendicular to the plane where the second folded edge 02 is located, the length of the second protective structure 142 is less than the third folded edge 03.

[0081] The first protective structure 141 and the supporting structure 130 are integrally provided, and the first protective structure 141 and the second protective structure 142 are separately provided to protect the display panel 110 .

[0082] In some embodiments, Fig.14 This is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Fig.14 As shown, along the direction perpendicular to the plane where the first folded edge 01 is located, the length of the first protective structure 141 is equal to the sum of the lengths of the support structure 130, the display panel 110 and the optical device 122, and along the direction perpendicular to the plane where the second folded edge 02 is located, the length of the second protective structure 142 is less than the third folded edge 03.

[0086] like Figure 10-15 As shown in any figure, compared with the related art, in order to achieve the front appearance and supporting effect, it is necessary to use several of the middle frame, foam tape, double-sided tape and sealant to fix the display panel 110 to one side of the back panel 121, resulting in a complex overall structure and the use of more assembly components, and an assembly scheme with certain structural risks. The embodiment of the present application uses the back panel 121 to position the display panel 110 and adjusts the internal structure of the back panel bend, without affecting the display effect and without increasing the structural risk. The number of assembly components is effectively reduced, the backlight structure is simplified, and then the assembly process is simplified, the assembly efficiency is improved, and the material cost in low-end models can be reduced.

[0087] Exemplarily, the materials used to prepare the first protective structure 141, the supporting structure 130 and the second protective structure 142 may be polyethylene terephthalate (PET) material, ethylene propylene rubber (EPDM) material, acrylonitrile butadiene styrene copolymer (ABS) material or other materials, which are not limited here.

[0088] In some embodiments, Fig.16 This is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Fig.11 Based on Fig.16 The display device further includes: a first adhesive structure 150 and a second adhesive structure 160 .

[0089] The first adhesive structure 150 is located on the surface of the first protective structure 141 facing the second folded edge 02, and the second adhesive structure 160 is located on the surface of the support structure 130 facing the optical device 122. When the first protective structure 141 and the support structure 130 are separately arranged, by arranging the first adhesive structure 150 on the surface of the first protective structure 141 facing the second folded edge 02, and arranging the second adhesive structure 160 on the surface of the support structure 130 facing the optical device 122, the first protective structure 141 is fixed to the second folded edge 02, and the support structure is fixed to the optical device 122, thereby ensuring the stability of the display panel 110.

[0090] In some embodiments, Fig.17 This is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Fig.16 Based on Fig.17 When the first protective structure 141 and the supporting structure 130 are separately arranged, the supporting structure 130 is fixed to the optical device 122 by the second adhesive structure 160 to further stably support the display panel 110. Fig.16 The structure shown, Fig.17 The structure shown reduces the first adhesive structure 150, and the size of the first protective structure 141 can be set according to actual design requirements so as to be closely attached to the second folded edge 02, thereby reducing material costs.

[0091] In some embodiments, Fig.18 This is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Fig.10 Based on Fig.18 When the first protective structure 141 and the supporting structure 130 are integrally arranged, the integrated first protective structure 141 and the supporting structure 130 are fixed to the second folding edge 02 by the first adhesive structure 150 and supported by the optical device 122. Fig.15 The structure shown, Fig.17 The structure shown reduces the second adhesive structure 160 , which not only ensures the stability of supporting the display panel 110 , but also further reduces the material cost.

[0092] In some embodiments, Figure 10-15 As shown in any figure, the first adhesive structure 150 can also be arranged on the surface of the second protective structure 142 facing the third folded edge 03, and the positions of the first adhesive structure 150 and the second adhesive structure 160 can be arranged according to the assembly requirements of the display device, for example, see Figure 16-Figure 18 , not limited here.

[0093] Exemplarily, the first adhesive structure 150 and the second adhesive structure 160 may be pre-coated adhesive, for example, transparent adhesive, oily adhesive, water-based adhesive or other types of adhesive. In this way, compared with the related art that requires the use of multiple layers of double-sided adhesive or foam tape to support the display panel 110, the embodiment of the present application reduces the number of double-sided adhesive or foam tapes, improves the stability of supporting the display panel 110 and saves component (or material) costs. The specific types of the first adhesive structure 150 and the second adhesive structure 160 are not limited herein.

[0094] In some embodiments, Fig.19 A schematic diagram of the layout structure of a support structure on the surface of an optical device provided in an embodiment of the present application. Fig.18 Based on Fig.19 In this top view, the surface of the optical device 122 facing the display panel 110 includes N edges.

[0095] Wherein, N is greater than or equal to 3, so as to reserve at least one of the N sides and to arrange the support structure 130 on at least two of the N sides. Exemplarily, the surface of the optical device 122 facing the display panel 110 may include three sides, four sides, or five sides, which may be arranged according to the shape of the display panel 110 and actual support requirements, and are not limited here.

[0096] like Fig.19 As shown, the surface of the optical device 122 facing the display panel 110 includes four sides, namely a first side, a second side, a third side and a fourth side. For example, the first side, the second side, the third side and the fourth side may be the top side, the bottom side, the left side and the right side, respectively, and the support structure 130 is located at the top side, the left side and the right side; in addition, the support structure 130 may also be located at two opposite sides such as the left side and the right side, or the top side and the bottom side to improve the stability of supporting the display panel 110, or may be located at other positions, which are not limited here.

[0097] In this way, while ensuring the stability of the display panel 110, at least one of the N sides can be reserved for placing and assembling other related components. It should be noted that after the other related components have been placed, the support structure 130 can be arranged on the reserved side, so as to realize the surrounding arrangement of the support structure 130 on the surface of the optical device 122.

[0098] Exemplarily, the support structure 130 may be a preset number of cubic structures or rectangular structures. For example, on the surface of the optical device 122 facing the display panel 110, rectangular structures with preset intervals may be arranged on the corresponding edges, or closely attached rectangular structures may be arranged. The arrangement may be based on actual design requirements of the support structure 130 and is not limited here.

[0099] Fig. 20This is a schematic diagram of the layout structure of another support structure on the surface of an optical device provided in an embodiment of the present application. Fig. 20 As shown, the support structure 130 can be set at preset distances, such as the support structure 130 as a whole forming three sections as shown in the figure; in addition, the support structure 130 can be set on the surface of an optical device such as an optical film, and the corners of each section of the support structure 130 are attached along the rounded corners and / or right angles of the optical film in the figure, and are attached along the edges of the optical film to avoid the problem of debonding caused by the support structure 130 exceeding the surface of the optical film.

[0100] In some embodiments, Figure 21-24 As shown in any figure, the backlight module also includes: a light-emitting unit (not shown in the figure).

[0101] The light emitting unit is located on the side of the bottom plate facing the optical device, that is, the light emitting unit is located between the bottom plate and the optical device. Specifically, the light emitting unit irradiates the initial light emitted by it to the optical device, which redistributes the initial light and further irradiates the display panel 110 to realize imaging.

[0102] The optical device includes: a reflective sheet 1221 , a diffuser plate 1222 and an optical film 1223 .

[0103] Among them, the reflective sheet 1221, the diffuser plate 1222 and the optical film 1223 are sequentially arranged in a direction away from the light-emitting unit, that is, the reflective sheet 1221, the diffuser plate 1222 and the optical film 1223 are sequentially overlapped on the first folded edge 01. Specifically, the reflective sheet 1221 first reflects the initial light to form a reflected light, and after the reflected light is transmitted to the diffuser plate 1222, the diffuser plate 1222 diffuses and evens the light to form an even light light, and after the even light light is irradiated to the optical film 1223, the optical film 1223 adjusts the brightness of the even light light to form an imaging light.

[0104] Exemplarily, the optical film 1223 can be a brightness enhancement film, which utilizes the principles of refraction and reflection of light to concentrate the uniform light, thereby improving the overall brightness and uniformity of the uniform light, thereby achieving a brightening effect, thereby forming imaging light that is ultimately incident on the display panel 110 to achieve imaging. The optical film 1223 can also be set to other types of films with brightening effects, which are not limited here.

It should be noted that the light-emitting unit support and control component locking area are located on the base plate 1211, and the light-emitting unit can be driven to light up by the control component. For example, the light-emitting unit can be a light strip, and the specific shape of the light-emitting unit is not limited here.
