Detailed ways

As described in the background art, the LED display screen in the related art includes a plurality of display units, which are spliced together to form LED display screens of different sizes, and at least one splicing point is formed on the LED display screen. In the related art, after splicing a plurality of display units at the same splicing point, the plurality of display units need to be fastened to a prefabricated steel structure by fasteners such as screws, so as to ensure the stability of the LED display screen by the steel structure.

However, during the process of fastening several display units to the steel structure by fasteners, the display units may shift in position relative to the steel structure, making it difficult to control the splicing gap between several display units fastened to the same steel structure, which may affect the consistency of the splicing gap at the splicing point of the LED display screen, and further affect the installation accuracy of the LED display screen.

In view of this, an embodiment of the present invention provides a distance connecting member and a display device. By setting at least one distance arm unit in the distance connecting member, when the distance arm unit is matched and connected with the distance holes on the adjacent display units in the display device, the consistency of the splicing gap of the display device at the splicing point can be ensured, thereby improving the installation accuracy of the display device.

The structure of the distance connector according to the embodiment of the present invention will be further described below in conjunction with the accompanying drawings.

Example

As shown in reference to FIG1 , the distance connection member provided in the embodiment of the present invention can be applied to a display device, and the display device includes mutually spliced display units 100. As shown in reference to FIG2 and FIG3 , the distance connection member 300 includes at least one distance arm unit 310, and the distance arm unit 310 includes a distance arm body 312 and two distance parts 311, and the distance arm body 312 is located between two adjacent display units 100, and the two distance parts 311 are located at two ends (not marked in the figure) on the same side of the distance arm body 312, so as to cooperate with the display unit 100 to realize the connection of the distance arm unit 310 to the two adjacent display units 100.

Referring to FIG. 2 and in combination with FIG. 1 , the distance portion 311 is inserted into the distance hole 1131 of the display unit 100 so that the distance arm unit 310 connects two adjacent display units 100. In this way, the two distance portions 311 in the distance arm unit 310 are inserted into the distance holes 1131 on the two adjacent display units 100, so that the distance arm unit 310 can connect two adjacent display units 100. Since the distance between the two distance portions 311 on the same distance arm unit 310 is relatively fixed (taking into account the factors that the processing tolerance affects the distance between the two distance portions 311), the splicing gap between the two adjacent display units 100 is also relatively fixed, so that the distance function between different display units 100 is realized through the distance connector 300, the consistency of the splicing gap between adjacent display units 100 in the display device is ensured, and the installation accuracy of the display device is improved.

As shown in FIG. 2 , the two ends of the distance arm body 312 correspond to the corners of the two display units 100 (not shown in the figure), and are connected to the corners of the two display units 100 through the distance parts 311. In this way, on the basis of the two display units 100 being spliced together at the corners, the distance connector 300 is located at the corners of the display units 100, so that the two distance parts 311 of the distance arm unit 310 are inserted into the distance holes 1131 at the corners of the two display units 100, and the distance arm unit 310 is used to connect and distance the two display units 100. At the same time, the distance hole 1131 is located at the corner of the display unit 100, which can also facilitate the splicing of at least two display units 100 at the corners, and the connection and distance functions of at least two display units 100 are realized through the distance connector 300.

2 and 3 , the distance portion 311 is a distance column, which is inserted into the distance hole 1131 and is interference fit with the distance hole 1131 to achieve the connection between the distance arm unit 310 and the adjacent display unit 100. Exemplarily, the distance column may include but is not limited to a connection protrusion on the distance arm body 312.

As shown in reference to FIG. 2 and FIG. 3 , the distance connector 300 may include a distance arm unit 310, and the distance connector 300 may connect two display units 100 adjacent to each other on the periphery of the display device. Specifically, distance holes 1131 are respectively provided at the corners of the two display units 100 adjacent to each other on the periphery of the display device, and two distance parts 311 in the distance arm unit 310 may be respectively inserted into a distance hole 1131, so that the distance arm unit 310 may be bridged over the two display units 100 adjacent to each other on the periphery of the display device, thereby realizing the connection and distance function of the two display units 100, ensuring the consistency of the splicing gap between the two display units 100, and pre-positioning the connected display units 100 through the distance connector 300 to avoid the positional displacement of the display units 100 relative to the steel structure, thereby improving the installation accuracy of the periphery of the display device.

In some embodiments, the distance connector 300 can also be used after the display unit 100 is connected to the steel structure, so as to adjust the relative position of two adjacent display units 100 on the steel structure through the distance connector 300, ensure the consistency of the splicing gap between the display units 100, and realize the distance function. Therefore, in the invention, the installation order of the distance connector 300 in the display device is not further limited.

As shown in FIG4 , in some embodiments, the distance connector 300 may further include a plurality of (for example, more than two) distance arm units 310, and the distance arm bodies 312 of the plurality of distance arm units 310 are connected end to end to form a closed structure, and each distance portion 311 is located on the same side of the closed structure to connect a plurality of mutually spliced display units 100. In this way, two adjacent display units 100 can be connected through each distance arm unit 310 in the distance connector 300, so that the distance connector 300 can help ensure the consistency of the splicing gap between adjacent display units 100 in at least one direction of the X direction and the Y direction, thereby improving the installation accuracy of the display device while connecting a plurality of mutually spliced display units 100.

As shown in Fig. 4, the distance connecting member 300 may include four distance arm units 310, and the distance arm bodies 312 of the four distance arm units 310 are connected end to end to form a closed structure. The closed structure may include but is not limited to a square ring structure (as shown in Fig. 4) or an arc-shaped ring structure.

In some embodiments, the distance connecting member 300 may further include two or other number of distance arm units 310. Taking two distance arm units 310 as an example, the distance arm bodies 312 of the two distance arm units 310 may be connected end to end to form a closed structure of other shapes.

It should be noted that the number of the distance arm units 310 in the distance connector 300 depends on the number of display units 100 to be connected. In this embodiment, no further limitation is made to the structure of the distance connector 300. According to the different numbers of the distance arm units 310 in the distance connector 300, the distance connector 300 can be set at different positions of the display device, so as to meet the connection and distance requirements between different display units 100 at different positions of the display device, so as to ensure the consistency of the splicing gap between adjacent display units 100 in at least one direction of the X direction and the Y direction, and improve the installation accuracy of the display device.

For example, when the distance connection member 300 includes one distance arm unit 310, it can be arranged on the peripheral side of the display device. For example, referring to FIG. 5 and FIG. 6 in combination with FIG. 4 , when the distance connection member 300 includes four distance arm units 310, it can be arranged in the middle of the display device (not marked in the figure) or on the side of the peripheral side of the display device toward the center (not marked in the figure) to connect multiple display units 100 spliced together.

In other embodiments, when the distance connecting member 300 includes a plurality of distance arm units 310, the plurality of distance arm units 310 may also be independent structures. The plurality of distance arm units 310 may be arranged on the display device at intervals along the length direction of the display device (such as the X direction in FIG. 1 ), so as to connect a plurality of display units 100 that are different in the length direction while ensuring the consistency of the splicing gaps between two adjacent display units 100 in the length direction.

Alternatively, a plurality of distance arm units 310 may be arranged on the display device at intervals along the width direction of the display device (such as the Y direction in FIG. 1 ) to connect a plurality of different display units 100 in the width direction while ensuring the consistency of the splicing gap between two adjacent display units 100 in the width direction.

The structure of the distance connecting member 300 is further described below by taking the closed structure formed by four distance arm units 310 as an example.

Referring to FIG. 7 and in combination with FIG. 4 , the distance arm unit 310 includes two first distance arm units 310a and two second distance arm units 310b, which are arranged opposite to each other. The two second distance arm units 310b are connected between the two first distance arm units 310a so as to be connected with the two first distance arm units 310a and form a closed structure with the two first distance arm units 310a, which is used to realize the connection and distance function of four different display units 100, so as to ensure the consistency of the splicing gap between each adjacent display unit 100 in at least one direction of the X direction and the Y direction, and improve the installation accuracy of the display device. The connection effect of the distance connector 300 on the four display units 100 is shown in FIG. 8 .

Specifically, the first distance arm unit 310a and the second distance arm unit 310b each include a distance arm body 312 and two distance parts 311. The distance arm bodies 312 of the two second distance arm units 310b can be connected between the two first distance arm units 310a, so that the distance arm bodies 312 of the four distance arm units 310 are connected end to end to form a closed structure.

As shown in FIG. 7 and FIG. 8 , two first distance arm units 310a are connected between two adjacent display units 100 in the first direction, and the second distance arm unit 310b is connected between two adjacent display units 100 in the second direction, and the second direction is different from the first direction. The first direction may include but is not limited to the length direction of the display device (i.e., the X direction in the figure), and the second direction may include but is not limited to the width direction of the display device (i.e., the Y direction in the figure). In this way, the two first distance arm units 310a are connected between two adjacent display units 100 in the first direction, and the two adjacent display units 100 in the first direction are connected respectively. Since the distance between the two adjacent distance parts 311 in the first distance arm unit 310a is relatively fixed, the two first distance arm units 310a can also ensure the consistency of the splicing gap between each adjacent display unit 100 in the first direction (i.e., the Y direction), thereby improving the installation accuracy of the display device.

Similarly, by connecting two adjacent display units 100 in the second direction through two second distance arm units 310b, the consistency of the splicing gaps between adjacent display units 100 in the second direction (ie, the X direction) can be ensured, thereby improving the installation accuracy of the display device.

The distance between the two distance parts 311 on the first distance arm unit 310a is equal to the distance between the two distance parts 311 on the second distance arm unit 310b, that is, the distance between the two distance parts 311 on the distance arm unit 310 in the distance connector 300 is equal. Since the distance parts 311 on the distance connector 300 correspond to the distance holes 1131 on the four display units 100 one by one, the distance between the two distance parts 311 on each distance arm unit 310 is equal, and when the four display units 100 spliced to each other are connected by four distance arm units 310, the two distance parts 311 on each distance arm unit 310 cooperate with the distance holes 1131 of two adjacent display units 100, so as to ensure the consistency of the splicing gap between each adjacent display unit 100 in the X direction and the Y direction, and further improve the installation accuracy of the display device.

Referring to FIG7 and in combination with FIG4 , the connection between the first distance arm unit 310a and the second distance arm unit 310b shares a distance portion 311, that is, adjacent distance arm units 310 share a distance portion 311. When there are four distance arm units 310 on the distance connecting member 300, since adjacent distance arm units 310 share a distance portion 311, the distance connecting member 300 has four distance portions 311.

Since the distance between the two distance parts 311 on each distance arm unit 310 is equal, when adjacent distance arm units 310 share one distance part 311, the distance between two adjacent distance parts 311 on the distance connector 300 will be equal. The distance holes 1131 have the same position and size at each corner of the display unit 100, and when four display units 100 are spliced together, the four distance holes 1131 correspond to the four distance parts 311 one by one.

In this way, while realizing the connection of the four display units 100 by the distance connecting member 300 and ensuring the consistency of the splicing gaps between adjacent display units 100 in the X direction and the Y direction, it is possible to reduce the number of distance parts 311 on the distance connecting member 300 and the number of distance holes 1131 at the corners of the display unit 100, thereby simplifying the structure of the distance connecting member 300 and the display unit 100, shortening the assembly process of the distance connecting member 300 on the display unit 100, and improving the splicing efficiency of the display unit 100 and the installation efficiency of the display device, and there is no need to limit the position of the distance connecting member 300 relative to the four display units 100, thereby further improving the splicing efficiency of the display unit 100 and the installation efficiency of the display device.

Since the distance portions 311 are located at the two ends of the distance arm body 312, when the distances between the two distance portions 311 on each distance arm unit 310 are equal, the length of the second distance arm unit 310b is equal to the length of the first distance arm unit 310a, that is, the lengths of the four distance arm units 310 in the distance connector 300 are the same.

The following takes four display units 100 as an example to further illustrate the connection and spacing principle of the spacing connector 300.

As shown in Fig. 5 and Fig. 6, a first joint 410 and a second joint 420 perpendicular to each other are formed between the four display units 100 spliced together. The distance connector 300 is located at the intersection of the first joint 410 and the second joint 420. Referring to Fig. 7 and Fig. 8, the two first distance arm units 310a are perpendicular to the first joint 410 and are arranged opposite to each other on both sides of the second joint 420, so that the two distance parts of the two first distance arm units 310a are inserted into the distance holes 1131 of the two connected display units 100, so as to realize the connection between the four display units 100 along the extension direction of the first joint 410 (i.e., the Y direction in the figure), and ensure the consistency of the splicing gap between the four display units 100 in the extension direction of the first joint 410 of the display device.

The two second distance arm units 310b are both perpendicular to the second joint 420 and are arranged opposite to each other on both sides of the first joint 410, so that the two distance portions 311 of the two second distance arm units 310b are passed through the distance holes 1131 of the two connected display units 100, thereby realizing the connection between the four display units 100 along the extension direction of the second joint 420 (i.e., the X direction in the figure), and ensuring the consistency of the splicing gaps between the four display units 100 in the extension direction of the second joint 420 of the display device.

As shown in reference figure 8, the distance connector 300 also includes a connecting arm 320, which is connected to at least one of the middle and end parts of the distance arm body 312, so as to enhance the stability of the distance connector 300 structure through the connection between the connecting arm 320 and the distance arm unit 310.

As shown in Fig. 3, when the distance connection member 300 includes only one distance arm unit 310, the connection arm 320 is located on the side of the distance arm unit 310. The connection arm 320 may include but is not limited to a "T"-shaped structure as shown in Fig. 3, so that the connection arm 320 can be connected to the middle and end of the distance arm body 312 to form the distance connection member 300.

Referring to Figures 4 and 8, when the distance connecting member 300 is a closed structure, the connecting arm 320 can be located inside the closed structure. The connecting arm 320 can include but is not limited to a "cross" structure as shown in Figure 8, so that the connecting arm 320 can be connected to the middle of the distance arm body 312 of each distance arm unit 310 to form the distance connecting member 300.

It should be noted that, in order to save the manufacturing cost of the distance connector 300, with reference to FIG. 3 and FIG. 4, the middle part of the second distance arm unit 310b of the distance connector 300 in FIG. 4 can be cut by cutting or the like to form two distance connectors 300 including only one distance arm unit 310 (as shown in FIG. 3). At this time, the structure of the second distance arm unit 310b remaining after cutting can constitute a part of the connecting arm 320. In this way, only one structure of the distance connector 300 needs to be designed, and a distance connector 300 with different numbers of distance arm units 310 can be formed as needed to meet the requirements of different connection positions and distances of the distance connector 300 in the display device, and can also simplify the manufacturing cost of the distance connector 300.

Referring to Figures 7 and 8, the connecting arm 320 is embedded in the joint 400 (such as the first joint 410 and the second joint 420) of two adjacent display units 100, and forms a hollow area 330 with the distance arm unit 310, so that on the basis of enhancing the structural stability of the distance connector 300 through the connecting arm 320, the distance connector 300 can also avoid the structure on the display unit 100 through the setting of the hollow area 330, so that the connecting arm 320 and the distance arm unit 310 can be embedded in the display device, and the distance connector 300 can be hidden by the thickness of the display unit 100, so as to reduce or avoid the installation space occupied by the distance connector 300 on the display unit 100.

In some embodiments, the distance connecting member 300 may also include two distance arm units 310, and the two distance arm units 310 may include a first distance arm unit 310a and a second distance arm unit 310b, and the distance arm bodies 312 of the first distance arm unit 310a and the second distance arm unit 310b are connected to each other, and the first distance arm unit 310a and the second distance arm unit 310b share a distance portion 311 at the connection between the distance arm bodies 312, and the first distance arm unit 310a and the second distance arm unit 310b can connect three different display units 100.

Among them, the first distance arm unit 310a can be connected between two adjacent display units 100 in the length direction of the display device, and the second distance arm unit 310b can be connected between two adjacent display units 100 in the width direction of the display device. The distance between the two distance parts 311 on the first distance arm unit 310a and the second distance arm unit 310b is equal. In this way, while connecting three different display units 100 through the distance connector 300, it can also ensure the consistency of the splicing gaps formed by the three different display units 100 in the length direction and the width direction of the display device, thereby improving the installation accuracy of the display device.

On the basis of the above, as shown in Figures 7 and 8, an embodiment of the present invention further provides a display device, which includes a plurality of mutually spliced display units 100 and the above-mentioned distance connecting members 300, and the distance connecting members 300 are located at the splicing point 400 of at least two mutually spliced display units 100 to connect at least two display units 100.

In this way, while connecting at least two display units 100 through the distance connecting member 300, the consistency of the splicing gap of at least two display units 100 at the splicing point 400 can be ensured. By the distance connecting member 300's distance-fixing function of the splicing gap between the connected display units 100, the consistency of the splicing gap of the display device at the splicing point can be ensured, thereby improving the installation accuracy of the display device.

As shown in FIGS. 7 and 8 , the display unit 100 includes a lamp board bottom shell 10, and a distance hole 1131 is provided at a corner of the lamp board bottom shell 10. The distance arm unit 310 of the distance connector 300 has two distance portions 311, and the two distance portions 311 are respectively inserted into the distance holes 1131 of the two lamp board bottom shells 10 to connect the two lamp board bottom shells 10. Since the lamp board bottom shell 10 is located on the non-display surface of the display unit 100 (not shown in the figure), the distance connector 300 can connect the two adjacent display units 100 by connecting the two lamp board bottom shells 10, and at the same time, it can also prevent the existence of the distance connector 300 from affecting the display of the display unit 100.

It should be noted that the lamp panel bottom shell 10 can have multiple (for example, two or four) corners, and each corner is provided with a spacing hole 1131, so that when the display unit 100 is spliced in different directions, it can cooperate with the spacing part 311 on the spacing connector 300, thereby realizing the connection of multiple different display units 100 through the spacing connector 300.

9 and 10, the display device includes a fixing member 200 (such as the above-mentioned steel structure) adsorbed to the bottom shell 10 of the light board, the fixing member 200 is located at the joint 400 of the adjacent bottom shells 10 of the light board, and is pressed on the side of the distance connecting member 300 facing away from the display unit 100. Exemplarily, the display unit 100 may include but is not limited to an LED display unit.

In this way, due to the setting of the distance connecting member 300 in the display device, before the bottom shell 10 of the light panel is adsorbed onto the fixing member 200, different display units 100 can be connected through the distance connecting member 300, and the connected display units 100 can be pre-positioned to ensure the consistency of the splicing gap between different display units 100 of the display device, thereby improving the installation accuracy of the display device.

Furthermore, the fixing member 200 is pressed against the side of the distance connecting member 300 facing away from the display unit 100 , which can also enhance the connection effect between the distance arm unit 310 and the display unit.

It should be noted that the distance connecting member 300 can also be used after the lamp panel bottom shell 10 is adsorbed on the fixing member 200. For details, please refer to the relevant description above and no further limitation is made here.

The structure of the display device is further described below by taking the application of the distance connecting member 300 before the lamp panel bottom shell 10 is adsorbed onto the fixing member 200 as an example.

The fixing member 200 may be a hollow tubular structure (such as a square tube), so that while the display device is supported by the fixing member 200 , the weight of the display device can also be reduced due to the hollow design of the fixing member 200 .

It should be noted that the display device, by arranging a plurality of spacing connectors 300 at intervals along the extension direction (such as the X direction) of the same joint 400, can achieve connection of a plurality of display units 100 on both sides of the joint 400 while also achieving consistency in the splicing gaps between the display units 100 on both sides of the joint 400, thereby improving the installation accuracy of the display device.

Continuing to refer to FIG. 11 and in combination with FIG. 7 , the corner of the lamp panel bottom shell 10 has a groove 113 that matches the structure of the distance arm body 312 in the distance arm unit 310, and the distance hole 1131 is located in the groove 113. When at least two lamp panel bottom shells 10 are spliced together, the grooves 113 of the lamp panel bottom shells 10 are spliced together and form an embedding groove (not shown in the figure). As shown in FIG. 8 , the distance connector 300 is embedded in the embedding groove to connect at least two lamp panel bottom shells 10, thereby realizing the connection and distance requirements of at least two display units 100, and also enabling the distance connector 300 to be embedded and fixed on the first mounting surface 11 of different lamp panel bottom shells 10, so as to utilize the thickness of different lamp panel bottom shells 10 to hide the distance connector 300, reduce the influence of the existence of the distance connector 300 on the thickness of the display device, and facilitate the adsorption of the fixing member 200 and the lamp panel bottom shell 10.

The two ends of the distance arm unit 310 can be respectively embedded in the grooves 113 of the two light board bottom shells 10, so that the distance arm unit 310 is bridged over two adjacent light board bottom shells 10, thereby realizing the connection between the two adjacent light board bottom shells 10, ensuring the consistency of the splicing gaps between the multiple display units 100 on both sides of the same splicing point 400, and at the same time, the thickness of the light board bottom shell 10 can be used to hide the thickness of the distance arm unit 310, so as to reduce the influence of the existence of the distance arm unit 310 on the thickness of the display unit 100 and the display device, and facilitate the adsorption of the fixing part 200 and the light board bottom shell 10.

Based on the cooperation between the distance portion 311 and the distance hole 1131, the groove 113 is arranged to enhance the assembly stability of the distance arm unit 310 and the distance connector 300 on the lamp board bottom shell 10, so as to enhance the stability of the connection between the distance connector 300 and different lamp board bottom shells 10.

Continuing to refer to FIG. 7 , the groove 113 may be located at the corner of the first mounting surface 11 of the lamp panel bottom shell 10. When four display units 100 are spliced together, the grooves 113 at one of the corners of the four lamp panel bottom shells 10 are spliced together to form an embedding groove. When one of the corners of two display units 100 on the peripheral side of the display device are spliced together, the structure of the embedding groove formed by splicing the grooves 113 at the corners of the two display units 100 also changes accordingly.

It should be noted that, depending on the structure of the embedding groove, a distance connector 300 adapted to the embedding groove structure may be used in the display device to achieve connection between different display units 100 at different positions of the display device by the distance connector 300 .

The following takes the example of the first distance arm unit 310a connecting two adjacent lamp board bottom shells 10 to illustrate the connection between different lamp board bottom shells 10 by the distance connector 300.

For the sake of convenience, the two lamp board bottom shells 10 are defined as the first lamp board bottom shell 10a and the second lamp board bottom shell 10b. Referring to FIG7 , the first end 312a of the first distance arm unit 310a can be embedded in the groove 113 of the first lamp board bottom shell 10a, and the distance portion 311 on the first end 312a is embedded in the distance hole 1131 of the first lamp board bottom shell 10a. The second end 312b of the first distance arm unit 310a can be embedded in the groove 113 of the second lamp board bottom shell 10b, and the distance portion 311 on the second end 312b is embedded in the distance hole 1131 of the second lamp board bottom shell 10b.

In this way, the first distance arm unit 310a is bridged across the first light board bottom shell 10a and the second light board bottom shell 10b to achieve splicing of the first light board bottom shell 10a and the second light board bottom shell 10b. Since the two first distance arm units 310a in the distance connecting piece 300 are equal in length, the distance hole 1131 and the distance portion 311 are arranged relative to each other, so that the position and size of the distance hole 1131 on the light board bottom shell 10 are also relatively fixed. Therefore, through the two first distance arm units 310a in the distance connecting piece 300, while connecting the first light board bottom shell 10a and the second light board bottom shell 10b, the consistency of the splicing gap between the multiple (for example, four) display units 100 on both sides of the first splicing point 410 of the display device can be ensured.

Similarly, through the two second distance arm units 310b in the distance connecting member 300, the consistency of the splicing gap between multiple (for example, four) display units 100 on both sides of the second splicing point 420 of the display device can be ensured. For details, please refer to the above description of the first distance arm unit 310a, which will not be further elaborated in this embodiment.

Continuing to refer to FIG. 11 , the display unit 100 further includes a display light board 20 , which is located on the second mounting surface 12 of the light board bottom shell 10 . The second mounting surface 12 and the first mounting surface 11 are two surfaces on the light board bottom shell 10 that are opposite to each other.

Referring to FIG. 11 and FIG. 12 , in order to realize the adsorption of the display unit 100 and the fixing member 200, the display unit 100 further includes an insert 50 and a magnetic member 60, and both the fixing member 200 and the insert 50 are configured to be magnetically adsorbed with the magnetic member 60. The insert 50 is embedded in the groove 111 of the first mounting surface 11 and is formed integrally with the lamp board bottom shell 10, so as to reduce the process of manually locking the insert 50 in the later stage, and effectively improve the installation efficiency of the display device. Among them, the insert 50 can be understood as a part added to the lamp board bottom shell 10 before the lamp board bottom shell 10 is manufactured and formed.

Continuing to refer to FIG. 11 , the display unit 100 includes an integrated circuit board 40 and a cover plate 30. The middle portion of the first mounting surface 11 of the lamp panel bottom shell 10 has a baffle 112. The baffle 112 and the lamp panel bottom shell 10 form a cavity (not shown in the figure) that can accommodate the integrated circuit board 40. The integrated circuit board 40 is accommodated in the cavity and plugged with the display lamp panel 20 to supply power to and control the display lamp panel 20. The cover plate 30 is covered on the baffle 112 to seal the cavity.

Referring to Figures 11 and 12, the magnetic member 60 can be accommodated in the accommodating groove 51 of the insert 50, and the display unit 100 can be adsorbed on the fixing member 200 through the insert 50, so that after different display units 100 are connected through the fixed distance connecting member 300, they can be directly adsorbed on the fixing member 200 through the insert 50 to achieve the connection between the display unit 100 and the fixing member 200, so that different display units 100 can be supported by the fixing member 200.

It should be noted that both the fixing member 200 and the insert 50 can be metal parts, magnetic plastic parts or other structures that can be magnetically adsorbed with the magnetic member 60. In this embodiment, the materials of the fixing member 200 and the insert 50 are not further limited.

Referring to FIG. 12 and in combination with FIG. 10 and FIG. 4 , the side of the distance connector 300 (not shown in the figure) facing the fixing member 200 is an exposed surface 340. The exposed surface 340 can be flush with the first mounting surface 11, so that the distance connector 300 can be hidden by the thickness of the lamp panel bottom shell 10, so that the setting of the distance connector 300 does not increase the thickness of the display device, thereby avoiding the setting of the distance connector 300 affecting the thickness of the display device, so as to achieve a thin and light display device.

When the adsorption end surface 52 of the insert 50 adsorbs the fixing member 200 and is flush with the first mounting surface 11 , the exposed surface 340 is flush with the first mounting surface 11 , which can ensure that the fixing member 200 fits the first mounting surface 11 , so as to achieve adsorption of the fixing member 200 and the insert 50 .

In addition, since the distance connector 300 is located at the joint 400 , the fixing member 200 can also be pressed and abutted against the exposed surface 340 of the distance connector 300 (as shown in FIG. 10 ), so as to further fix the distance connector 300 through the fixing member 200 .

Alternatively, in some embodiments, on the basis of ensuring the connection strength between adjacent display units 100 at the joint 400, the exposed surface 340 may also be lower than the first mounting surface 11, that is, when the distance connector 300 is embedded in the first mounting surface 11, a recessed area is formed on the first mounting surface 11 of the distance connector 300 that is recessed toward one side of the display light board 20. In this embodiment, the positional relationship between the exposed surface 340 and the first mounting surface 11 is not further limited.

As shown in reference figure 11, the groove 113 can be located on the side of the insert 50 and set towards the edge of the first mounting surface 11, so that different lamp board bottom shells 10 can form an embedding groove when they are spliced together. The distance connecting member 300 is embedded in the embedding groove to achieve the splicing between different lamp board bottom shells 10, and it can also help to miniaturize the distance connecting member 300, so as to further reduce the installation space occupied by the distance connecting member 300 on each lamp board bottom shell 10.

The display device of the embodiment of the present invention is provided by the distance connector 300 , which can not only realize the connection between different display units 100 in the display device, but also ensure the consistency of the splicing gaps between different display units 100 , thereby improving the installation accuracy of the display device.
