As shown in fig. 1, 2, and 3, the display device according to the embodiment of the present invention includes a back plate 1 and a frame 2, a gap exists between the back plate 1 and the frame 2, the display device further includes an adaptor 3 for connecting the back plate 1 and the frame 2, and the adaptor 3 includes a first connecting portion 31 fixedly connected to the frame 2, and a second connecting portion 32 fixedly connected to the back plate 1. For the same size of display device, because the size of domestic display device's backplate 1 is less than commercial display device's backplate 1, when being applied to commercial display device with domestic display device's backplate 1, there is the clearance between backplate 1 and the frame 2, for the convenience of being connected fixedly between backplate 1 and the frame 2, be equipped with the adaptor 3 that is used for connecting backplate 1 and frame 2 between backplate 1 and frame 2, adaptor 3 includes the first connecting portion 31 that is close to frame 2 and the second connecting portion 32 that is close to backplate 1, first connecting portion 31 is connected fixedly with frame 2, second connecting portion 32 is connected fixedly with backplate 1. Compared with the commercial display device in the prior art, the edge of the back plate extends out of the side edge of the display module and is fixed with the frame 2 in a contact manner. According to the display device provided by the embodiment of the invention, the backboard 1 and the frame 2 are connected and fixed through the adapter piece 3, and the backboard 1 and the frame 2 can be connected and fixed without extending the backboard 1 to the position contacting with the frame 2, so that the backboard 1 can be used for a household display device and a commercial display device, the generalization of the backboard 1 is realized, the production efficiency of the display device is improved, and the manufacturing cost is reduced.

In order to realize the generalization between the back panel 1 of the home display device and the back panel 1 of the commercial display device, the back panel 1 of the home display device may be applied to the commercial display device, or the back panel 1 of the commercial display device may be applied to the home display device. Because commercial display device's backplate 1 is great, its edge stretches out display module's side and contacts with frame 2, if be applied to domestic display device with commercial display device's backplate 1, then can't realize domestic display device's narrow frame design, make domestic display device's outward appearance relatively poor, be unfavorable for promoting user's use and experience. Therefore, the display device of the embodiment of the present invention realizes the generalization of the back panel 1 by applying the back panel 1 of the home display device to the commercial display device. And solved through increasing adaptor 3, when being applied to commercial display device with domestic display device's backplate 1, there is the clearance between backplate 1 and the frame 2 brought, inconvenient backplate 1 and the frame 2 between be connected fixed problem.

Referring to fig. 2 and 3, the frame 2 has a plurality of sides, including a first side wall 21 close to the back plate 1 along the thickness direction of the display device, a second side wall 22 far away from the back plate 1, a third side wall 23 close to the back plate 1 along the plane of the display device, and a fourth side wall 24 far away from the back plate 1. In the display device according to the embodiment of the invention, as shown in fig. 2, the extending direction of the first connecting portion 31 is parallel to the extending direction of the first sidewall 21, and the first connecting portion 31 overlaps the first sidewall 21. Compared with the method that the first connecting portion 31 is abutted against the third side wall 23 and is fixedly connected with the third side wall 23, the first connecting portion 31 is overlapped on the first side wall 21, the contact position of the first connecting portion 31 and the first side wall 21 can be adjusted according to the size of the gap between the back plate 1 and the frame 2, the mounting precision requirement is low, the mounting and manufacturing are convenient, and the manufacturing efficiency of the display device can be improved. The first connecting part 31 is fixedly connected with the frame 2 through a threaded connecting structure; through threaded connection structural connection, can make things convenient for the dismantlement between first connecting portion 31 and the frame 2 to make things convenient for the maintenance in display device later stage and the change of relevant spare part.

The thickness direction of the display device is a direction perpendicular to the display device or a direction perpendicular to the plane of the rear plate 1. Commercial display devices are generally less prone to damage because of their better reliability. The first connecting portion 31 may also be configured to be parallel to the third sidewall 23 and contact with the third sidewall 23, and the first connecting portion 31 and the third sidewall 23 are inconvenient to be connected and fixed by a threaded connection structure and may be fixed by adhesion; when the first connection portion 31 is fixedly bonded to the bezel 2, an adhesive having a high viscosity is selected to ensure the reliability of the bonding.

In the display device according to the embodiment of the present invention, the screw connection structure includes a through hole located on the first connection portion 31, and a screw for connecting the first connection portion 31 and the bezel 2. First connecting portion 31 overlap joint is on first lateral wall 21, and in order to realize when the size in the clearance between backplate 1 and frame 2 changes, first connecting portion 31 all can be fixed with the effectual connection of frame 2, and the through-hole is the slot hole along the direction of the lateral wall of perpendicular to backplate 1, and when display device the installation error appeared, when the clearance size between backplate 1 and frame 2 changed, the screw can remove along the direction of perpendicular to lateral wall in the through-hole, wherein, the lateral wall is the lateral wall that is close to the through-hole of backplate 1. The threaded connection structure further comprises a threaded hole which is located on the frame 2 and corresponds to the through hole, and a screw penetrates through the through hole and is screwed into the threaded hole to fix the first connection part 31 on the frame 2.

The threaded connection structure may also be self-tapping screw, and in this case, no matter how large the gap is, the first connection portion 31 can be fixed to the frame 2 only by enabling the first connection portion 31 to be overlapped with the first sidewall 21.

The second connecting portion 32 is matched with the backboard 1, as shown in fig. 2 and 3, in order to facilitate the connection of the second connecting portion 32 with the backboard 1, the structure and the relative position relationship of the second connecting portion 32 are both adapted to the direction of the backboard 1, so that the second connecting portion 32 can be connected and fixed with the backboard 1. In order to facilitate the detachment between the adaptor 3 and the back plate 1, the second connecting portion 32 is fixedly connected to the back plate 1 through a threaded connection structure.

In order to facilitate the manufacturing of the adapters 3 and the assembling of the display device, as shown in fig. 4 and 5, in the display device according to the embodiment of the present invention, the number of the adapters 3 is four, the four adapters 3 are respectively located on four side edges of the backplane 1, and each side edge is correspondingly provided with one adapter 3. The display device of the embodiment of the invention further comprises a display module 4 positioned on one side of the back plate 1 along the thickness direction, a circuit board or other electronic elements or structural components are usually arranged on the lower side edge of the display module 4, and the electronic elements or the structural components extend out of the panel for a certain length along the extension direction of the display module 4. The left side, the upper side and the right side of the display module 4 have the same structure, and the structure does not extend out of the panel, so that the adaptor 3 and the different sides of the back plate 1 are connected and fixed conveniently, and the structure requirements of the display module 4 are met. The four adapters 3 are divided into two structures, including a first adapter 3a located on the left side of the backboard 1, a first adapter 3a located on the right side of the backboard 1 and a first adapter 3b located on the upper side of the backboard 1, and a second adapter 3b located on the lower side of the backboard 1.

Referring to fig. 2, 6 and 7, in the thickness direction of the display device, the second connection portion 32a of the first connector 3a is located on a side of the backplate 1 away from the display module 4, and the second connection portion 32a includes a contact surface 321 contacting the backplate 1, and the contact surface 321 is attached to a side wall of the backplate 1 away from the display module 4. The shape and structure of the second connecting portion 32a are adapted to the side wall of the back plate 1 attached to the second connecting portion 32 a. The width of the second connection portion 32a contacting the back plate 1 can be determined according to the size of the display device, and when the size of the display device is large, the attaching area of the second connection portion 32a and the back plate 1 can be properly increased to reduce the stress between the second connection portion 32a and the back plate 1, and prevent the second connection portion 32a and the back plate 1 from being extruded and deformed. When the second connecting portion 32a and the back plate 1 are fixed by the threaded connection structure, optionally, a through hole is formed in the second connecting portion 32a, a threaded hole is formed in the back plate 1 at a position corresponding to the through hole, and the second connecting portion 32a is fixed to the back plate 1 by a screw.

As shown in fig. 2, 6 and 7, since the second connecting portion 32a is attached to the back plate 1, a reinforcing plate 322 for increasing the structural strength of the adaptor 3 is disposed at a portion of the second connecting portion 32a close to the edge of the back plate 1, and a hollow structure is disposed between the reinforcing plate 322 and the second connecting portion 32a to reduce the weight of the adaptor 3. The second connecting portion 32a and the back plate 1 may be connected and fixed by other methods such as clamping, bonding or welding, but compared with a threaded connection structure, the clamping and bonding reliability is poor, and when the display device shakes, the second connecting portion 32a and the back plate 1 may be connected and failed, so that they are separated from each other; although the welding is firm and reliable, it is not favorable for the later maintenance and replacement of the display device.

In the display device of the embodiment of the invention, as shown in fig. 3, the side of the back plate 1 is provided with the bent portion 11, the bent portion 11 can assist in fixing the display module 4, when the display device is vertically placed, the display module 4 abuts against the bent portion 11, the bent portion 11 can support the weight of the display module 4, and the display module 4 and the back plate 1 are placed to be separated due to fixing failure. Because the second adapter 3b is located at the lower side of the back plate 1, if the second adapter is similar to the second connecting portion 32a of the first adapter 3a, the second connecting portion 32b of the second adapter 3b is connected and fixed with the side of the back plate 1 away from the display module 4, when the display device is vertically placed, the weight of the display module 4 and the weight of the back plate 1 are all pressed on the threaded connection structural member (for example, a screw) between the second connecting portion 32b and the back plate 1, the requirement on the strength of the threaded connection structural member is high, and when the weight of the display module 4 and the weight of the back plate 1 are large, the strength failure of the threaded connection structural member may be caused. In order to prevent the above problem, in the display device according to the embodiment of the invention, the second connection portion 32b of the second adaptor 3b is located on a side of the bent portion 11 away from the back plate 1, that is, in fig. 1, the second connection portion 32b is located on a lower side of the bent portion 11, and the second connection portion 32b of the second adaptor 3b is parallel to the bent portion 11, so as to increase a contact area between the second connection portion 32b and the bent portion 11. The second connecting portion 32b is connected to the bent portion 11 of the back plate 1 through a threaded connection structure, as shown in fig. 3, optionally, the threaded connection structure includes a mounting hole located on the second connecting portion 32b, a threaded hole located on the bent portion 11 and corresponding to the mounting hole, and a screw for connecting the second adaptor 3b to the back plate 1. In order to better transmit the weight of the display module 4 and the back plate 1 to the frame 2, as shown in fig. 3 and 8, one side of the second connecting portion 32b away from the back plate 1 abuts against the frame 2.

As shown in fig. 3, a buffer is provided between the display module 4 and the bent portion 11 and the second connecting portion 32 b. On one hand, the buffer member can prevent the display module 4 or the backboard 1 from directly contacting the second connecting portion 32b to press and deform the display module 4 or the backboard 1. On the other hand, the buffer member may fill up the gap between the bent portion 11 of the rear panel 1 and the frame 2, so that the thickness of the second connecting portion 32b perpendicular to the bent portion 11 is not too thick.

The display device of the embodiment of the invention further comprises a display module 4, and the display module 4 is positioned on one side of the back plate 1 along the thickness direction of the display device. As shown in fig. 2 and 3, along the thickness direction of the display device, one side of the display module 4 is fixedly connected with the backboard 1, and the other side of the display module is abutted against the frame 2, so that the display module 4 cannot displace along the thickness direction of the display device. In order to prevent the display module 4 from moving along the plane of the back plate 1, as shown in fig. 2 and 6, the adaptor 3 further includes a limiting portion 33 for limiting the movement of the display module 4 relative to the back plate 1, the limiting portion 33 is perpendicular to the plane of the display module 4, and the limiting portion 33 abuts against a sidewall of the display module 4, which is a side surface of the display module perpendicular to the plane of the display module. Four directions of display module assembly 4 all lean on with spacing portion 33 and lean on, make display module assembly 4's position keep static for backplate 1 and frame 2, and display device's structure is more reliable and more stable.

The limiting portion 33 can directly abut against the side of the display module 4, or a buffer can be added between the side of the display module 4 and the limiting portion 33 to indirectly abut against the limiting portion 33 and the display module 4. In order to ensure the connection reliability between the backboard 1 and the frame 2, the adaptor 3 is usually made of a material with high hardness and strength, and the buffer member can prevent the display module 4 or the backboard 1 from directly contacting the second connecting portion 32b to extrude the display module 4 or the backboard 1.

Due to the structural difference between the first adapter 3a and the second adapter 3b, the position-limiting portions 33 of the first adapter 3a and the second adapter 3b are not identical. As shown in fig. 2, 6 and 7, since the second connecting portion 32a of the first connecting member 3a is close to the contact surface 321 of the back plate 1 and attached to the back plate 1, the limiting portion 33 of the first connecting member 3a is perpendicular to the first connecting portion 31 and the second connecting portion 32 a. As shown in fig. 3, 8 and 9, the second connecting portion 32b of the second adaptor 3b is perpendicular to the plane of the display module 4 and abuts against the sidewall of the display module 4, so that the position-limiting portion 33 of the second adaptor 3b is parallel to the second connecting portion 32a and both are the same side plate (the side plate indicated by 32b in fig. 8 and 9). The difference is that, if the second connecting portion 32a is only used for being connected and fixed with the back panel 1, along the thickness direction of the display device, the width of the side panel only needs to be the same as the bending portion 11, in order to make the side panel play the role of the limiting portion 33, because the side panel also includes the portion abutted against the display module 4, the width of the side panel is wider.

As needed to be applied to outdoor or various industrial occasions, in order to prevent rainwater or other impurities from contacting the display module 4 and damaging the display module 4, the display device according to the embodiment of the present invention further includes a cover plate 5 for protecting the display module 4, as shown in fig. 2 and 3, and the cover plate 5 is located on one side of the display module 4 away from the backplane 1. In order to prevent the cover plate 5 from affecting the light display effect of the display device, the cover plate 5 is made of a material with good light transmittance, for example, the cover plate 5 may be glass. Generally, in order to enhance the protection effect of the cover plate 5, the impact received by the cover plate 5 is prevented from being directly transmitted to the display module 4, and the cover plate 5 is in contact with the non-display module 4 in a fitting manner, i.e., a gap exists between the cover plate 5 and the display module 4. In order to connect and fix the frame 2 of the cover plate 5 and keep the cover plate 5 stationary relative to the display device, the adaptor 3 further includes a third connecting portion 34 for connecting the frame 2 and the cover plate 5, as shown in fig. 2 and 3, the third connecting portion 34 and the limiting portion 33 are connected and fixed near one side of the cover plate 5, the third connecting portion 34 is parallel to the cover plate 5, the third connecting portion 33 is located between the display module 4 and the cover plate 5, one side of the third connecting portion 34 abuts against the display module 4 to be connected, and the other side is connected and fixed with the cover plate 5. In order to reduce the contact area between the third connecting portion 34 and the cover plate 5 and reduce the machining surface of the third connecting portion 34 on the side close to the cover plate 5, a connecting protrusion 341 is arranged on the side close to the cover plate 5 of the third connecting portion 34, and the cover plate 5 is fixed to the connecting protrusion 341 in an adhering manner.

Referring to fig. 4 and 5, in order to facilitate the manufacturing of the adapters 3 and the installation of the display device, the number of the adapters 3 is four, and the four adapters 3 are respectively located on one side edge of the backplane 1. In order to increase the connection stability between the back plate 1 and the frame 2, in the display device according to the embodiment of the invention, the two adapters 3 located at two adjacent sides of the back plate 1 are connected and fixed, so that the four adapters 3 are connected and fixed into a whole. If the four adapters 3 are not connected and fixed into a whole, when the outside of the display device is collided and shakes along one direction, the force generated between the frame 2 and the back plate 1 can be transmitted only through the adapter 3 on one side, and the stress of the adapter 3 is uneven; when connecting four adaptor 3 as a whole, the power that produces between frame 2 and backplate 1 can transmit through four adaptor 3 jointly, makes display device's structure more stable.

In the display device according to the embodiment of the invention, the structures of the first adapters 3a located on the left side, the right side and the upper side of the back plate 1 and the second adapters 3b located on the lower side of the back plate 1 are not completely the same, and the connection modes of the two adjacent adapters 3 are different when the two adapters are fixedly connected. Referring to fig. 4, 10 and 11, two adjacent first connectors 3a are connected and fixed by a connecting piece 6, and the connecting piece 6 includes two connecting portions 61 perpendicular to each other, one of the connecting portions 61 is connected and fixed with one of the two adjacent first connectors 3a, and the other connecting portion 61 is connected and fixed with the other first connector 3 a. Optionally, the first adapter 3a and the connecting portion 61 are fixedly connected by a threaded connection structure, and the threaded connection structure includes a mounting hole on the first adapter 3a, a threaded hole corresponding to the mounting hole on the connecting portion 61, and a screw for connecting the first adapter 3a and the connecting member 6. Optionally, in order to increase the reliability of the connection between the first connectors 3a and the connectors 6, two threaded connections are provided between each first connector 3a and the connector 6.

Due to the structural difference between the second adapter 3b and the first adapter 3a, the second adapter 3b and the first adapter 3a are not suitable for being fixedly connected by the connecting piece 6. As shown in fig. 4, 12, and 13, in the display device according to the embodiment of the present invention, the second adaptor 3b and the first adaptor 3a are connected and fixed by the limiting structure 7, the limiting structure 7 includes a limiting protrusion 71 and a limiting hole 72, the limiting protrusion 71 is located on one adaptor 3 of the first adaptor 3a and the second adaptor 3b, and the limiting hole 72 is located on the other adaptor 3 of the first adaptor 3a or the second adaptor 3 b. As shown in fig. 12 and 13, the display device according to the embodiment of the present invention includes a limiting protrusion 71 provided on the first adapter 3a, and a limiting hole 72 provided on the second adapter 3 b.

It should be noted that, alternative arrangement schemes of the limiting protrusion 71 and the limiting hole 72 include: the limiting protrusion 71 is arranged on the first adapter 3a, and the limiting hole 72 is arranged on the second adapter 3 b; or, the limiting projection 71 is arranged on the second adapter 3b, and the limiting hole 72 is arranged on the first adapter 3 a; or, one section of the first adapter 3a is provided with a limiting protrusion 71, the other end is provided with a limiting hole 72, one end of the second adapter 3b corresponding to the limiting protrusion 71 is provided with the limiting hole 72, and one end corresponding to the limiting hole 72 is provided with the limiting protrusion 71.
