[0003] However, the structural design of related display devices still has many shortcomings, making it difficult to effectively ensure their drop and impact resistance while achieving a thinner and lighter design. Therefore, how to improve the impact resistance of display devices without increasing their thickness has become an urgent technical problem to be solved. Summary of the Invention

[0004] Embodiments of this application provide a display device that improves the impact resistance of the display device without increasing its thickness.

[0005] A display device includes: a display panel having a target area at its edge, the target area extending along a first direction; a support member extending along the first direction corresponding to the target area, the support member having a continuous support surface for conforming to the target area and a groove located on the side of the continuous support surface opposite to the display panel, the continuous support surface being continuously distributed on a plane formed by the first direction and a second direction perpendicular to the first direction; and a back plate disposed on the side of the support member opposite to the display panel, the back plate including a reinforcing portion corresponding to the groove; the reinforcing portion being located within at least a portion of the projection range of the continuous support surface; so that the target area forms a support path with the reinforcing portion through the continuous support surface.

[0006] According to an embodiment of this application, the depth of the groove portion along the third direction is D, the distance between the reinforcing portion and the continuous support surface in the third direction is L, and D and L satisfy: D>L, and the third direction is perpendicular to the first direction and the second direction.

[0007] According to an embodiment of this application, the support member has a through portion communicating with the groove portion on the side opposite to the display panel, the through portion passing through at least one end of the support member in the second direction, and at least a portion of the reinforcing portion is located in the through portion.

[0008] According to an embodiment of this application, the reinforcing part includes a reinforcing wall and an extended wall having an angle with the reinforcing wall, the reinforcing wall having an angle with the plane formed by the first direction and the second direction.

[0009] According to an embodiment of this application, the reinforcing wall includes a first wall and a second wall, the extension direction of the first wall intersects the extension direction of the second wall, and a plurality of reinforcing portions are provided at intervals along the first direction.

[0010] According to an embodiment of this application, the support member includes a covering portion located on the side of the extended wall opposite to the display panel, and the side of the covering portion opposite to the display panel is flush with the side of the back plate opposite to the display panel.

[0011] According to an embodiment of this application, the display panel includes an array substrate and a color filter substrate disposed on the side of the array substrate opposite to the back plate. The array substrate has an extension protruding from the color filter substrate in a second direction. The target area includes the extension.

[0015] The display device provided in this application has at least the following advantages compared with related technologies:

[0016] In this embodiment, the display device supports the target area of ​​the display panel through a continuous support surface provided on the support member. This ensures that the force transmitted through the target area is evenly distributed along the extension direction of the continuous support surface, thus preventing stress concentration in the support member and avoiding damage to the target area. This improves the lifespan of the display device. Simultaneously, by providing a groove on the side of the support member away from the continuous support surface and a reinforcing portion corresponding to the groove on the back plate, the support strength of the back plate is increased, further preventing damage to the target area. Furthermore, this facilitates the molding of the support member, increasing its yield and reducing the manufacturing cost of the display device. Attached Figure Description

Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0033] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact with the first and second features through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "aspect," "specific example," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

[0036] As display devices become increasingly thinner and lighter, their overall thickness and weight continue to decrease. However, the array substrate in the display panel needs to electrically connect integrated circuits and other circuits such as flexible circuit boards, so its edge area is usually formed with a single-layer structure. This single-layer structure is significantly weaker than the double-layer structure of the display area and is more prone to breakage upon impact.

[0037] To improve the structural stability of this single-layer structure, display devices typically incorporate internal support components. However, due to the inherent structural design of these support components, stress concentration often occurs in the localized contact between the support components and the edge area of ​​the display panel. This makes the edge area of ​​the display panel prone to cracking when the display device is dropped or subjected to external impact, thus affecting the lifespan of the display device.

[0038] Therefore, how to improve the impact resistance of display devices without increasing their thickness has become an urgent technical problem to be solved.

[0039] To improve the impact resistance of the display device without increasing its thickness, refer to Figures 1 to 9 This application discloses a display device including a display panel 1, a support member 2, and a back plate 3. The display panel 1 has a target area 111 at its edge, extending along a first direction. The support member 2 extends along the first direction corresponding to the target area 111, and has a continuous support surface 211 for conforming to the target area 111 and a groove 213 located on the side of the continuous support surface 211 facing away from the display panel 1. The continuous support surface 211 is continuously distributed on a plane formed by the first direction and a second direction perpendicular to the first direction. The back plate 3 is disposed on the side of the support member 2 facing away from the display panel 1, and includes a reinforcing portion 31 corresponding to the groove 213. The reinforcing portion 31 is located within at least a portion of the projection range of the continuous support surface 211, so that the target area 111 forms a support path with the reinforcing portion 31 through the continuous support surface 211.

[0040] Understandably, the target area 111 extends along the first and second directions. The recess 213 has a groove-shaped structure, and the opening of the recess 213 is located on the side of the continuous support surface 211 opposite to the display panel 1. At least a portion of the reinforcing portion 31 extends into the recess 213 through the opening of the recess 213, and at least a portion of the reinforcing portion 31 projected toward the continuous support surface 211 is located within the continuous support surface 211.

[0041] It should be noted that the "continuous support surface 211 is continuously distributed on the plane formed by the first direction and the second direction perpendicular to the first direction" mentioned above means that the continuous support surface 211 extends continuously on the plane formed by the first direction and the second direction, that is, the continuous support surface 211 extends without any breaks on the plane formed by the first direction and the second direction.

[0042] Since the support member 2 is provided with a continuous support surface 211 for fitting the target area 111 and a groove 213 located on the side of the continuous support surface 211 away from the display panel 1, the first continuous support surface 211 is continuously distributed on the plane formed by the first direction and the second direction. This increases the support area of ​​the support surface on the target area 111, so that when the display device is dropped or subjected to external impact, the impact force is evenly distributed on the continuous support surface 211, so as to avoid the large local stress between the support member 2 and the target area 111, which may cause the target area 111 to break. This improves the impact resistance of the display device. On the other hand, it also increases the yield of the support member 2, thereby reducing the manufacturing cost of the display device.

[0043] Furthermore, since the back plate 3 includes a reinforcing part 31 corresponding to the groove 213, and the reinforcing part 31 is located within at least a portion of the projection range of the continuous support surface 211, the structural strength of the back plate 3 corresponding to the support member 2 is increased in the first aspect, thereby improving the support effect of the back plate 3 on the support member 2; in the second aspect, the target area 111 forms a support path through the continuous support surface 211 and the reinforcing part 31, thereby improving the support effect of the support member 2 on the target area 111, thus improving the impact resistance of the display device without increasing the thickness of the display device; in the third aspect, the cooperation between the reinforcing part 31 and the groove 213 can be used to position the support member 2, thereby facilitating the precise installation of the support member 2 and improving the assembly efficiency of the display device; in the fourth aspect, the cooperation between the reinforcing part 31 and the groove 213 can be used to limit the position of the support member 2, thereby increasing the stability of the support member 2 and further increasing the support effect of the support member 2 on the target area 111, thereby further improving the impact resistance of the display device.

[0044] This application does not specifically limit the depth of the groove 213 in its embodiments. In one implementation, refer to... Figure 5 The depth of the groove 213 along the third direction is D, and the distance between the reinforcing part 31 and the continuous support surface 211 in the third direction is L. D and L satisfy: D>L. The third direction is set perpendicular to the first direction and the second direction.

[0045] It is understandable that the dimension of support member 2 in the third direction is T, T=D+L, D>1 / 2T.

[0046] Since the depth of the groove 213 along the third direction is greater than the distance between the reinforcing part 31 and the continuous support surface 211 in the third direction, on the one hand, the yield of the support member 2 can be further improved, thereby further reducing the manufacturing cost of the display device; on the other hand, the structural strength of the reinforcing part 31 can be improved, thereby further improving the support effect of the reinforcing part 31 on the support member 2. At the same time, the distance between the reinforcing part 31 and the continuous support surface 211 can be smaller, thereby further improving the support effect of the continuous support surface 211 on the target area 111, and thus further improving the impact resistance of the display device.

[0047] In other embodiments, the depth of the groove 213 in the third direction may be less than or equal to the distance between the reinforcing part 31 and the continuous support surface 211 in the third direction.

[0048] In one implementation, reference Figure 2 , Figure 4 , Figure 5 and Figure 7 The support member 2 has a through portion 214 that communicates with the groove portion 213 on the side opposite to the display panel 1. The through portion 214 passes through at least one end of the support member 2 in the second direction, and at least a portion of the reinforcing portion 31 is located in the through portion 214.

[0049] It is understood that the through portion 214 is a groove-shaped structure provided on the support member 2, and the through portion 214 has a first slot and a second slot connected to the first slot. The first slot is located on the side of the support member 2 away from the display panel 1, and the second slot is located on the end face of the support member 2 in the second direction.

[0050] Since the support member 2 has a through portion 214 connected to the groove portion 213 on the side away from the display panel 1, and the through portion 214 passes through at least one end of the support member 2 in the second direction, and at least a portion of the reinforcing portion 31 is located in the through portion 214, on the one hand, the yield of the support member 2 can be further improved, so as to further reduce the manufacturing cost of the display device; on the other hand, the volume of the reinforcing portion 31 can be increased to improve the structural strength of the reinforcing portion 31, thereby improving the support effect of the reinforcing portion 31 on the support member 2, further improving the support effect of the continuous support surface 211 on the target area 111, and thus further improving the impact resistance of the display device.

[0051] This application does not specifically limit the relationship between the depth of the through portion 214 in the third direction and the depth of the recessed portion 213 in the third direction in one embodiment. Figure 5 and Figure 7 The depth of the through portion 214 in the third direction is equal to the depth of the groove portion 213 in the third direction, that is, the bottom of the groove portion 213 is flush with the bottom of the groove portion 214. This allows the reinforcing portion 31 to fully contact the bottom of the groove portion 213 and the groove portion 214, ensuring the support area of ​​the reinforcing portion 31 on the support member 2, thereby further improving the support effect of the reinforcing portion 31 on the support member 2 and further improving the impact resistance of the display device. On the other hand, it also simplifies the structural design of the reinforcing portion 31, thereby further reducing the manufacturing cost of the display device.

[0052] Of course, in other embodiments, the depth of the through portion 214 in the third direction can be set to be different from the depth of the groove portion 213 in the third direction, and the end of the reinforcing portion 31 near the display panel 1 can be adapted to the bottom of the groove portion 213 and the bottom of the through portion 214, so as to further improve the structural strength of the reinforcing portion 31, thereby further improving the supporting effect of the reinforcing portion 31 on the support member 2, and further improving the impact resistance of the display device.

[0053] For example, refer to Figure 2 and Figure 4The display panel 1 has a liquid crystal area 13 and a sealing area 14 surrounding the liquid crystal area 13. The display device also includes a backlight module 4 disposed between the display panel 1 and the back plate 3. The backlight module 4 is disposed opposite to the liquid crystal area 13 and is used to provide uniform backlight illumination to the display panel 1. The support member 2 is located on the side of the backlight module 4. The through portion 214 passes through the end of the support member 2 near the backlight module 4 so that the projection of the reinforcing part 31 toward the display panel 1 can cover at least a part of the sealing area 14 or the distance between the projection of the reinforcing part 31 toward the display panel 1 and the sealing area 14 is closer, thereby improving the support stability of the reinforcing part 31 on the end of the support member 2 near the backlight module 4. This avoids the occurrence of stress concentration between the continuous support surface 211 and the target area 111 near the sealing area 14, thereby avoiding the occurrence of easy breakage of the target area 111 near the sealing area 14, and further improving the impact resistance of the display device.

[0054] This application does not specifically limit the structure of the reinforcing part 31 in the embodiments. In one embodiment, referring to... Figures 2 to 5 The reinforcing part 31 includes a reinforcing wall 311 and an extended wall 312 having an angle with the reinforcing wall 311. The reinforcing wall 311 has an angle with the plane formed by the first direction and the second direction.

[0055] It is understood that the back panel 3 also includes a flat panel 32, which is located on the side of the backlight module 4 away from the display panel 1. The reinforcing wall 311 is fixedly connected to the flat panel 32, and the extension wall 312 is fixedly connected to the reinforcing wall 311.

[0056] Since the reinforcing part 31 includes a reinforcing wall 311 and an extended wall 312 that forms an angle with the reinforcing wall 311, and the reinforcing wall 311 forms an angle with the parallel formed by the first direction and the second direction, the reinforcing wall 311 can be used to strengthen the structural strength of the reinforcing part 31 to ensure the supporting effect of the reinforcing part 31 on the support member 2. On the other hand, the extended wall 312 can be used to increase the connection area between the reinforcing part 31 and the support member 2 to further ensure the supporting effect of the reinforcing part 31 on the support member 2.

[0057] This application does not specifically limit the fixing connection method between the reinforcing wall 311 and the flat plate 32. In one embodiment, referring to... Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7The reinforcing wall 311 is integrally formed onto the flat plate 32 by stamping. This eliminates the need to separately assemble the reinforcing wall 311 onto the flat plate 32, reducing the manufacturing difficulty of the back plate 3 and improving the manufacturing efficiency of the back plate 3, thereby improving the manufacturing efficiency of the display device. On the other hand, it also increases the connection stability between the reinforcing wall 311 and the flat plate 32, thereby improving the structural strength of the relative parts of the back plate 3 and the support member 2, and further improving the impact resistance of the display device.

[0058] In other embodiments, the reinforcing wall 311 may also be fixedly connected to the flat plate 32 by welding or other means.

[0059] This application does not specifically limit the fixed connection method between the extended wall 312 and the reinforcing wall 311. In one embodiment, referring to... Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The extended wall 312 is integrally formed with the reinforcing wall 311 by stamping. This eliminates the need to separately assemble the extended wall 312 with the reinforcing wall 311, reducing the manufacturing difficulty of the back panel 3 and improving the manufacturing efficiency of the back panel 3, thereby improving the manufacturing efficiency of the display device. On the other hand, it also increases the connection stability between the extended wall 312 and the reinforcing wall 311, thereby improving the structural strength of the relative parts of the back panel 3 and the support member 2, and further improving the impact resistance of the display device.

[0060] In other embodiments, the extended wall 312 may also be fixedly connected to the reinforcing wall 311 by welding or other means.

[0061] This application does not specifically limit the included angle between the reinforcing wall 311 and the flat plate 32 in the embodiments. In one embodiment, referring to... Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The flat plate portion 32 is arranged parallel to the continuous support surface 211, and the reinforcing wall 311 forms a 90° angle with the flat plate portion 32, so that the reinforcing wall 311 extends in a direction perpendicular to the continuous support surface 211, so that the impact force transmitted through the continuous support surface 211 is transmitted along the extension direction of the reinforcing wall 311, thereby improving the reinforcing effect of the reinforcing wall 311 on the reinforcing portion 31, thereby improving the supporting effect of the reinforcing portion 31 on the support member 2, and further improving the impact resistance of the display device.

[0062] In other embodiments, the reinforcing wall 311 and the flat plate 32 may form an angle of other degrees, such as 85°, 80°, etc.

[0063] This application does not specifically limit the structure of the extended wall 312 in the embodiments. In one embodiment, refer to... Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The extended wall 312 is a flat plate structure and is set parallel to the continuous support surface 211. That is, the extended wall 312 is located on the plane formed by the first direction and the second direction. This can reduce the manufacturing difficulty of the back panel 3 and improve the manufacturing efficiency of the back panel 3. On the other hand, it can also reduce the manufacturing difficulty of the support member 2 to a certain extent, thereby increasing the yield of the support member 2 and further reducing the manufacturing cost of the display device.

[0064] In other embodiments, the extending direction of the extended wall 312 may intersect with the extending direction of the continuous support surface 211; or, the extended wall 312 may be an arc-shaped plate structure, a hemispherical structure, etc.

[0065] This application does not specifically limit the structure of the reinforcing wall 311, and it can adopt any of the following embodiments:

[0066] Example 1, in this example, refers to Figures 2 to 5 The reinforcing wall 311 includes a first wall 313 and a second wall 314. The extending direction of the first wall 313 intersects the extending direction of the second wall 314. Multiple reinforcing parts 31 are provided at intervals along the first direction.

[0067] It is understood that multiple grooves 213 and through-holes 214 are provided at intervals along the first direction, and each groove 213 and through-hole 214 is provided in a one-to-one correspondence with a reinforcing part 31, that is, each reinforcing part 31 extends into its corresponding groove 213 and through-hole 214.

[0068] It should be noted that, in this embodiment, the portion of the flat plate 32 located between two adjacent reinforcing portions 31 is also connected to the support member 2, so that the target area 111 can not only form a support path with the reinforcing portion 31 through the continuous support surface 211, but also form a support path with the portion of the flat plate 32 located between two adjacent reinforcing portions 31 through the continuous support surface 211.

[0069] Since the reinforcing wall 311 includes a first wall 313 and a second wall 314, and the extension direction of the first wall 313 intersects the extension direction of the second wall 314, the reinforcing wall 311 can not only strengthen the structural strength of the reinforcing part 31 on the plane formed by the first direction and the third direction, but also strengthen the structural strength of the reinforcing part 31 on the plane formed by the second direction and the third direction, so as to further improve the structural strength of the reinforcing part 31, thereby further improving the support effect of the reinforcing part 31 on the support member 2, so as to further ensure the support effect of the continuous support surface 211 on the target area 111, and further improve the impact resistance of the display device.

[0070] Furthermore, since multiple reinforcing parts 31 are spaced apart along the first direction, the reinforcing effect of the reinforcing parts 31 on the back plate 3 is improved, thereby improving the support effect of the back plate 3 on the support member 2. At the same time, the number of support points of the reinforcing parts 31 on the support member 2 is increased, thereby further improving the support stability of the reinforcing parts 31 on the support member 2, and thus further improving the impact resistance of the display device. On the other hand, the movement of the support member 2 in the first direction can be locked by the cooperation of the reinforcing parts 31 and the groove 213, thereby increasing the stability of the support member 2 and further improving the impact resistance of the display device.

[0071] Furthermore, referring to Figures 2 to 5 The reinforcing wall 311 also includes an arc-shaped wall 315 located between the first wall 313 and the second wall 314. One end of the arc-shaped wall 315 is fixedly connected to the first wall 313, and the other end of the arc-shaped wall 315 is fixedly connected to the second wall 314. That is, the first wall 313 is connected to the second wall 314 through the arc-shaped wall 315. This facilitates the molding of the reinforcing wall 311, thereby improving the yield of the back panel 3. On the other hand, it also avoids the possibility of injury to the assembly personnel due to the sharp edges between the first wall 313 and the second wall 314, thus improving the assembly experience of the assembly personnel for the display device.

[0072] For example, refer to Figures 2 to 5 The first wall 313 extends along the first direction, and the second wall 314 extends along the second direction. That is, the first wall 313 is located on the plane formed by the first direction and the third direction, and the second wall 314 is located on the plane formed by the second direction and the third direction, so as to reduce the difficulty of manufacturing the reinforcing part 31.

[0073] Of course, in other embodiments, the extension direction of the first wall 313 may also have an angle with the first direction, and the extension direction of the second wall 314 may also have an angle with the second direction, that is, the plane where the first wall 313 is located has an angle with the plane formed by the first direction and the third direction, and the plane where the second wall 314 is located has an angle with the plane formed by the second direction and the third direction.

[0074] This application does not specifically limit the number of the first wall body 313 and the second wall body 314 in its embodiments. In one embodiment, refer to... Figures 2 to 5 Two first wall bodies 313 and two second wall bodies 314 are provided. The two first wall bodies 313 are located at both ends of the extended wall body 312 in the second direction, and the two second wall bodies 314 are located at both ends of the extended wall body 312 in the first direction, so that the first wall body 313, the second wall body 314 and the arc-shaped wall body 315 together form a wall structure that extends continuously in the circumferential direction of the extended wall body 312, thereby further improving the structural strength of the reinforcing part 31, further improving the supporting effect of the reinforcing part 31 on the support member 2, and further improving the impact resistance of the display device.

[0075] Furthermore, referring to Figure 2 and Figure 4 At least a portion of the flat plate portion 32 protrudes from the side of the reinforcing portion 31 away from the backlight module 4, and the side of the flat plate portion 32 away from the backlight module 4 is bent towards the side where the display panel 1 is located to form a flange 321. The side of the support member 2 away from the backlight module 4 has a receiving portion corresponding to the flange 321. This further improves the structural strength of the back plate 3, thereby further improving the support effect of the back plate 3 on the support member 2. On the other hand, it can also increase the connection area between the support member 2 and the back plate 3, thereby increasing the connection stability between the support member 2 and the back plate 3. Furthermore, the flange 321 and the reinforcing portion 31 can be used to lock the support member 2 in the second direction, thereby further increasing the stability of the support member 2 and further improving the impact resistance of the display device.

[0076] In other embodiments, there may be only one first wall 313 and two second walls 314. The first wall 313 is located on the side of the extended wall 312 near the backlight module 4, and the two second walls 314 are located at both ends of the extended wall 312 in the first direction, so that the reinforcing part 31 has an opening on the side away from the backlight module 4, thereby allowing at least a portion of the support part 21 to extend into the interior of the reinforcing part 31 through the opening of the reinforcing part 31, thereby increasing the connection area between the support member 2 and the reinforcing part 31, and thus improving the connection stability between the support member 2 and the reinforcing part 31.

[0077] In this embodiment, the connection method between the back plate 3 and the support member 2 is not specifically limited. In one embodiment, the support member 2 is fixedly connected to the back plate 3 by adhesive, for example, the support member 2 is bonded to the back plate 3 by thermosetting resin adhesive, so as to increase the connection stability between the support member 2 and the back plate 3 and reduce the difficulty of fixing the support member 2.

[0078] In other implementation examples, when the support member 2 is made of plastic, the support member 2 can also be molded onto the back plate 3. That is, when manufacturing the support member 2, the back plate 3 is first placed in a mold, and then molten plastic is poured into the mold so that the molten plastic is directly solidified on the back plate 3, thereby eliminating the need for separate assembly of the support member 2 and thus improving the efficiency of display device manufacturing. Alternatively, when the support member 2 is made of other materials, the support member 2 can also be fixedly connected to the back plate 3 in other ways, such as screw fixing, riveting, etc.

[0079] Example 2, in this example, refer to Figure 8 The reinforcing wall 311 is a flat plate to simplify the structural design of the reinforcing part 31.

[0080] Furthermore, referring to Figure 8 The reinforcing wall 311 extends along the first direction, that is, the reinforcing wall 311 is located on the plane formed by the first direction and the third direction, so that the reinforcing part 31 can provide a continuous and uniform supporting force for the support member 2 in the first direction, so as to further avoid stress concentration between the continuous support surface 211 and the target area 111, thereby further improving the impact resistance of the display device.

[0081] Of course, in other embodiments, the extension direction of the reinforcing wall 311 may also have an angle with the first direction, that is, the plane in which the reinforcing wall 311 is located has an angle with the plane formed by the first direction and the third direction.

[0082] In this embodiment, the positional relationship between the reinforcing wall 311 and the extended wall 312 is not specifically limited. In one implementation example, refer to... Figure 8 The reinforcing wall 311 is located on the side of the extended wall 312 close to the backlight module 4. This can facilitate the production and manufacturing of the back panel 3, thereby improving the production and manufacturing efficiency of the back panel 3. On the other hand, it can also reduce the flattened area of ​​the back panel 3, thereby reducing the weight of the back panel 3 and facilitating the lightweight design of the display device.

[0083] In another implementation example, the reinforcing wall 311 may also be located on the side of the extended wall 312 away from the backlight module 4.

[0084] For example, the groove 213 passes through both ends of the support member 2 in the first direction, and the reinforcing wall 311 and the extending wall 312 are both continuously extended in the first direction. The ends of the reinforcing wall 311 and the extending wall 312 in the first direction are respectively flush with the ends of the support member 2 in the first direction, so that the reinforcing part 31 forms continuous support for the support member 2 in the first direction, thereby improving the support effect of the reinforcing part 31 on the support member 2, and further improving the impact resistance of the display device.

[0085] Furthermore, referring to Figure 8 and Figure 9 The support member 2 includes a covering part 22, which is located on the side of the extended wall 312 away from the display panel 1, and the side of the covering part 22 away from the display panel 1 is flush with the side of the back plate 3 away from the display panel 1.

[0086] It is understood that the support member 2 also includes a support portion 21, a covering portion 22 connected to the support portion 21, the support portion 21 is located on the side of the extended wall 312 facing the display panel 1, the groove portion 213 is provided on the support portion 21, and the side of the covering portion 22 away from the display panel 1 is flush with the side of the flat plate portion 32 away from the display panel 1.

[0087] Since the covering part 22 is located on the side of the extended wall 312 away from the display panel 1, and the side of the covering part 22 away from the display panel 1 is flush with the side of the back plate 3 away from the display panel 1, it can increase the connection area between the support member 2 and the back plate 3, thereby increasing the connection stability between the support member 2 and the back plate 3, and thus increasing the support stability of the continuous support surface 211 on the target area 111, thereby further improving the impact resistance of the display device; on the other hand, it can also avoid the situation where the volume of the display device increases due to the covering part 22 protruding from the side of the flat plate 32 away from the display panel 1, thereby achieving the effect of making the display device thinner and lighter.

[0088] Furthermore, referring to Figure 8The extended wall 312 includes a first extended wall segment 316 and a second extended wall segment 317. The first extended wall segment 316 is fixedly connected to the reinforcing wall 311, and the second extended wall segment 317 is fixedly connected to the first extended wall segment 316, i.e., the first extended wall segment 316 is located between the second extended wall segment 317 and the reinforcing wall 311; furthermore, the thickness of the second extended wall segment 317 in the third direction is greater than the thickness of the first extended wall segment 316 in the third direction. The groove portion 213 and / or the covering portion 22 are adapted to the extended wall 312, and then... On the one hand, it can further improve the yield rate of the support member 2, thereby further reducing the production and manufacturing cost of the display device; on the other hand, it can also increase the connection area between the extended wall 312 and the support member 2, thereby increasing the connection stability between the extended wall 312 and the support member 2, thus improving the support effect of the support member 2 on the target area 111; furthermore, it can also improve the structural strength of the reinforcing part 31, thereby improving the support effect of the reinforcing part 31 on the support member 2, and further improving the impact resistance of the display device.

[0089] For example, refer to Figure 8 The side of the second extension wall section 317 facing the display panel 1 is flush with the side of the first extension wall section 316 facing the display panel 1. That is, the side of the second extension wall section 317 away from the display panel 1 protrudes from the side of the first extension wall section 316 away from the display panel 1, and the covering part 22 is adapted to the extension wall 312. This makes the side of the extension wall 312 facing the display panel 1 continuously distributed on the plane formed by the first direction and the second direction, thereby improving the support effect of the extension wall 312 on the support member 2 and further improving the impact resistance of the display device. On the other hand, it also makes the groove 213 more regular, thereby simplifying the structural design of the groove 213.

[0090] This application does not specifically limit the formation method of the second extension wall segment 317 having a greater thickness in the third direction than the first extension wall segment 316 in the third direction. In one embodiment, the end of the extension wall 312 away from the reinforcing wall 311 is bent in the direction away from the display panel 1 and then folded towards the end where the reinforcing wall 311 is located and the side where the display panel 1 is located, so that the overlapping part of the extension wall 312 in the third direction forms the second extension wall segment 317, thereby reducing the difficulty of manufacturing the back panel 3.

[0091] In other embodiments, the second extension wall section 317 may also be formed by at least a partial thickening of the extension wall 312.

[0092] Furthermore, referring to Figure 8At least a portion of the support portion 21 is located on the side of the reinforcing wall 311 near the backlight module 4, and at least a portion of the support portion 21 is connected to the flat plate portion 32. This can further increase the connection area between the support member 2 and the back plate 3, thereby further increasing the connection stability between the support member 2 and the back plate 3. On the other hand, at least a portion of the flat plate portion 32 can be used to support the support member 2, so that the target area 111 can also form a support path through the continuous support surface 211 and at least a portion of the flat plate portion 32, thereby further improving the impact resistance of the display device.

[0093] In this embodiment, the connection method between the back plate 3 and the support member 2 is not specifically limited. In one embodiment, the support member 2 is made of plastic material and is formed on the back plate 3. That is, when manufacturing the support member 2, the back plate 3 is first placed in the mold, and then molten plastic is poured into the mold so that the molten plastic is directly solidified on the back plate 3, thereby eliminating the need to assemble the support member 2 separately, and thus improving the efficiency of display device manufacturing.

[0094] In other implementation examples, when the support member 2 is made of other materials, the support member 2 can also be fixedly connected to the back plate 3 in other ways, such as adhesive, screw fixing, riveting, etc.

[0095] In addition to the two embodiments described above, in other embodiments, the reinforcing wall 311 can also be an annular wall, a frustum wall with both the inner and outer circumferential surfaces being frustum-shaped, an elliptical wall, a C-shaped wall, an S-shaped wall, etc.

[0096] In other embodiments, the reinforcing part 31 may also be a rib structure separately provided on the side of the back plate 3 facing the display panel 1.

[0097] This application does not specifically limit the formation method of the target region 111 in the embodiments. In one embodiment, referring to Figure 2 , Figure 4 and Figure 8 The display panel 1 includes an array substrate 11 and a color filter substrate 12 disposed on the side of the array substrate 11 away from the back plate 3. The array substrate 11 has an extension protruding from the color filter substrate 12 in a second direction. The target area 111 includes the extension and a continuous support surface 211 is attached to the side of the extension away from the color filter substrate 12.

[0098] It is understandable that the extension section is used to electrically connect integrated circuits and other circuits such as flexible circuit boards. The projection of the extension section toward the back plate 3 does not coincide with the projection of the color filter substrate 12 toward the back plate 3, that is, the extension section constitutes a single-layer structure of the display panel 1.

[0099] Since the extension protrudes from the color filter substrate 12 in the second direction, the target area 111 includes the extension, and the continuous support surface 211 is attached to the side of the extension away from the color filter substrate 12. The continuous support surface 211 can then continuously support the single-layer structure of the display panel 1, so that the impact force transmitted through the target area 111 is evenly distributed on the continuous support surface 211. This avoids stress concentration on the support member 2, which could cause the display panel 1 to easily break in the target area 111, thereby improving the impact resistance of the display device.

[0100] This application does not specifically limit the way the continuous support surface 211 is attached to the target area 111 in the embodiments. In one embodiment, referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 A fixing layer 212 is provided between the array substrate 11 and the continuous support surface 211, and the fixing layer 212 is continuously distributed on the plane formed by the first direction and the second direction.

[0101] Understandably, the continuous support surface 211 is attached to the target area 111 through the fixing layer 212.

[0102] Since the fixing layer 212 is continuously distributed on the plane formed by the first and second directions, and the fixing layer 212 is located between the array substrate 11 and the continuous support surface 211, it can fix the continuous support surface 211 and the array substrate 11 together by using the fixing layer 212 to increase the connection stability between the support member 2 and the array substrate 11. On the other hand, it can also ensure the connection area between the continuous support surface 211 and the array substrate 11 through the fixing layer 212 to further increase the connection stability between the support member 2 and the array substrate 11. Furthermore, it can also avoid the situation where stress concentration easily occurs between the target area 111 and the continuous support surface 211 due to the discontinuity of the fixing layer 212 on the plane formed by the first and second directions, so as to further avoid the target area 111 of the display panel 1 being prone to cracking, thereby achieving the effect of increasing the impact resistance of the display device.

[0103] This application does not specifically limit the structure of the fixing layer 212. In one embodiment, the fixing layer 212 includes double-sided adhesive, which is continuously distributed on the plane formed by the first direction and the second direction. The two opposite sides of the double-sided adhesive are respectively bonded to the continuous support surface 211 and the array substrate 11. This achieves two effects: firstly, the continuous support surface 211 is bonded to the array substrate 11 using double-sided adhesive, thereby increasing the connection stability between the continuous support surface 211 and the array substrate 11; secondly, the slight elasticity of the double-sided adhesive itself can absorb the impact force between the continuous support surface 211 and the target area 111, thereby further improving the impact resistance of the display device; and thirdly, it can reduce the assembly difficulty of the display device, thereby improving the assembly efficiency of the display device.

[0104] In other embodiments, the fixing layer 212 includes structural adhesive applied between the continuous support surface 211 and the array substrate 11 to fix the continuous support surface 211 and the array substrate 11 together.

[0105] In other embodiments, the design of the fixing layer 212 can be omitted so that the continuous support surface 211 directly contacts the array substrate 11. That is, the "continuous support surface 211 for bonding the target area 111" mentioned in the embodiments of this application refers to the continuous support surface 211 contacting the side of the array substrate 11 away from the color filter substrate 12.

[0106] Furthermore, referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 The display panel 1 has a liquid crystal area 13 and a sealing area 14 surrounding the liquid crystal area 13, and a continuous support surface 211 is located within at least a portion of the projection range of the sealing area 14.

[0107] It is understood that the display panel 1 also includes a liquid crystal layer sandwiched between the array substrate 11 and the color filter substrate 12. The liquid crystal layer is located in the liquid crystal region 13 of the display panel 1, and the sealing region 14 is used to seal the liquid crystal layer. The sealing region 14 has a transition section located between the liquid crystal region 13 and the extension section, and at least a portion of the continuous support surface 211 projected toward the display panel 1 is located within the transition section.

[0108] Since the continuous support surface 211 is located within at least a portion of the projection area of ​​the sealing area 14, it increases the support area of ​​the support member 2 on the display panel 1. This allows the support member 2 to support not only the extension of the array substrate 11 but also at least a portion of the sealing area 14 of the display panel 1, thus avoiding stress concentration between the support member 2 and the display panel 1 and further improving the impact resistance of the display device. On the other hand, it also prevents the end of the support member 2 near the backlight module 4 from being located between the sealing area 14 and the extension, which could cause the display panel 1 to easily crack between the sealing area 14 and the extension when subjected to impact, thereby further improving the impact resistance of the display device.

[0109] Furthermore, referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 At least a portion of the fixed layer 212 projected toward the display panel 1 is located within the transition section, thereby increasing the fixed connection area between the continuous support surface 211 and the display panel 1, and further increasing the connection stability between the support member 2 and the display panel 1.

[0110] Furthermore, referring to Figure 2 and Figure 4 At least a portion of the reinforcing part 31 protrudes from the side of the support member 2 near the liquid crystal area 13, so that the reinforcing part 31 is located within at least a portion of the projection range of the sealing area 14.

[0111] It is understood that at least a portion of the reinforcing part 31 projected toward the display panel 1 is located within the sealing area 14, that is, at least a portion of the reinforcing part 31 projected toward the display panel 1 is located within the transition section.

[0112] It should be noted that the support member 2 has one end close to the backlight module 4 and one end away from the backlight module 4. The above-mentioned "at least part of the reinforcing part 31 protrudes from the side of the support member 2 close to the liquid crystal area 13" means that at least part of the reinforcing part 31 protrudes from the side of the support member 2 close to the backlight module 4, that is, at least part of the reinforcing part 31 projected toward the display panel 1 is located on the side of the support member 2 close to the backlight module 4.

[0113] Since at least a portion of the reinforcing part 31 protrudes from the side of the support member 2 near the liquid crystal area 13, the reinforcing part 31 can be located within at least a portion of the projection range of the sealing area 14, thereby preventing the back plate 3 from easily deforming at the location of the reinforcing part 31 and affecting the stability of the support member 2 by the reinforcing part 31, and further improving the impact resistance of the display device.

[0114] Furthermore, referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 At least a portion of the support member 2 protrudes from the side of the target area 111 away from the liquid crystal area 13, meaning that at least a portion of the continuous support surface 211 projected toward the display panel 1 does not coincide with the display panel 1; and at least a portion of the fixing layer 212 protrudes from the side of the target area 111 away from the liquid crystal area 13, meaning that at least a portion of the fixing layer 212 projected toward the display panel 1 does not coincide with the display panel 1. This ensures, on the one hand, that the continuous support surface 211 supports the entire target area 111, thereby ensuring the support effect of the support member 2 on the target area 111; on the other hand, it also ensures the connection area between the continuous support surface 211 and the target area 111, thereby increasing the connection stability between the support member 2 and the display panel 1; furthermore, it reduces the assembly difficulty of the display device, thereby improving the assembly efficiency of the display device.

[0115] In some embodiments, refer to Figure 2 , Figure 3 , Figure 4 and Figure 8 The display device also includes a cover plate 5, which is located on the side of the display panel 1 away from the back plate 3. The cover plate 5 and the extension section form a space for accommodating integrated circuits and flexible circuit boards. A support member 51 is provided between the cover plate 5 and the extension section.

[0116] Understandably, the two opposite sides of the support member 51 are respectively attached to the extension section and the cover plate 5, so as to use the support member 51 to support the side of the target area 111 away from the support member 2.

[0117] Since a support member 51 is provided between the cover plate 5 and the extension section, the support member 51 can be used to support the side of the target area 111 away from the support member 2, so as to further prevent the display panel 1 from easily breaking when subjected to impact force, thereby further improving the impact resistance of the display device.

[0118] This application does not specifically limit the structure of the support member 51. In one embodiment, multiple support members 51 are spaced apart along the first direction, and an accommodating space is formed between two adjacent support members 51 for the passage of circuits such as integrated circuits and flexible circuit boards. This can increase the number of support points of the support member 51 on the target area 111, thereby increasing the support effect of the support member 51 on the target area 111. On the other hand, it can also make the support member 51 avoid the integrated circuits and flexible circuit boards, thereby facilitating the assembly of the display device.

[0119] In other embodiments, the support member 51 may be continuously extended along the first direction, and the support member 51 is continuously distributed on the plane formed by the first and second directions on the side of the target area 111. The support member 51 is provided with a hole structure for circuits such as integrated circuits and flexible circuit boards to pass through, so as to increase the connection area between the support member 51 and the target area 111 while enabling the installation of circuits such as integrated circuits and flexible circuit boards, thereby increasing the support effect of the support member 51 on the target area 111.

[0120] The embodiments of this application do not specifically limit the structure of the support member 51. It can be a block structure or strip structure made of foam, or it can be a structure of other shapes made of other materials.

[0121] In other embodiments, the target area 111 may also include an extension and at least a portion of the sealing area 14.

[0122] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0123] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

In particular, the features described in the various embodiments of this application can be combined and / or combined in various ways without departing from the spirit and teachings of this application.
