Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to an LED light box, a display panel and a display device. Background Art

[0002] LED display screens display text, graphics, images, animations, videos and other information by turning on and off each light source on the light board. With the continuous development of LED technology, LED display screens are moving from small pitch to micro pitch. The smaller the pitch of the light board, the higher the requirements for assembly, that is, the higher the requirements for the gap and clearance between the light boards after splicing.

[0003] LED display screens are generally composed of multiple independent display modules seamlessly spliced ​​up and down, left and right. Each display module can be assembled by multiple light boards in the same box. Therefore, the difference and gap between the boxes can easily affect the difference and gap between the light boards after splicing.

[0004] At present, in relevant LED display screens, the flatness of the joints between cabinets is poor, which easily produces discontinuities and gaps, thereby causing discontinuities and gaps between light panels.

[0053] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0055] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0056] In the related art, for the LED light box 10 including multiple boxes 1, such as Figure 1 As shown, after the multiple boxes 1 are spliced ​​together, a support beam 6 and multiple locking members 7 are arranged on the back side of the box 1 (i.e., the side away from the light panel). The support beam 6 fits the back surface of the multiple boxes 1 and blocks the gap between two adjacent boxes 1. The multiple locking members 7 are crimped onto the support beam 6 and are fixedly connected to the multiple boxes 1 respectively. In this way, the splicing and assembly of the multiple boxes 1 is achieved through the cooperation of the support beam 6 and the locking members 7 to ensure the flatness of the multiple boxes 1 after assembly. However, in the related art, such as Figure 1 or Figure 2 As shown, after the multiple boxes 1 are spliced ​​and fixed, the splicing angle at the first splicing area 11 is prone to discontinuity, thereby affecting the flatness of the multiple boxes 1 and further affecting the flatness of the light board fixed on the LED light box 10.

[0057] Figure 3 A partial structural diagram of an LED light box 10 provided in an embodiment of the present disclosure is illustrated. Figure 4 The schematic diagram of the local structure of an LED light box 10 before being fixed provided by the embodiment of the present disclosure is illustrated. Figure 5 The following is a schematic diagram of the structure of a first connecting plate 21 provided in an embodiment of the present disclosure from an axial side bottom view. Figure 3 , Figure 4 and Figure 5As shown, the LED light box 10 includes: a plurality of boxes 1 and a plurality of first connecting members 2, the plurality of boxes 1 are spliced ​​in an array to form a plurality of first splicing areas 11, each of the first splicing areas 11 includes a plurality of splicing angles, and each of the splicing angles has a first fixing structure 111 and a first positioning hole 112; the plurality of first connecting members 2 correspond to the plurality of first splicing areas 11 one by one, each of the first connecting members 2 includes a first connecting plate 21 and a plurality of first fixing members 22, the first connecting plate 21 has a first surface and a second surface, and a plurality of first positioning columns located on the first surface 23, a plurality of first fixing members 22 correspond one-to-one to a plurality of first fixing structures 111 of a plurality of splicing corners, and a plurality of first positioning columns 23 correspond one-to-one to a plurality of first positioning holes 112 of a plurality of splicing corners; the first surface of the first connecting plate 21 covers a plurality of splicing corners at the corresponding first splicing area 11, a plurality of first positioning columns 23 are respectively located in the first positioning holes 112 on the plurality of splicing corners, a plurality of first fixing members 22 are respectively fixedly connected to the first fixing structures 111 on the plurality of splicing corners, and the first connecting plate 21 is fixed to the plurality of splicing corners.

[0058] In the embodiment of the present application, the multiple boxes 1 included in the LED light box 10 can be arranged in an array manner when being spliced. At this time, the multiple boxes 1 can constitute multiple first splicing areas 11, and then the corresponding first connecting parts 2 are respectively assembled at each first splicing area 11 to realize the assembly of multiple boxes 1. When assembling the corresponding first connecting parts 2 at each first splicing area 11, it can be based on the corresponding insertion of the multiple first positioning columns 23 of the first connecting plate 21 and the first positioning holes 112 of the multiple splicing corners at the corresponding first splicing area 11, and then the multiple first fixing parts 22 are respectively fixedly connected to the first fixing structures 111 on the multiple splicing corners at the corresponding first splicing area 11, so as to fix the first connecting plate 21 on the multiple splicing corners at the corresponding first splicing area 11, so as to realize the fixed connection between the multiple splicing corners.

[0059] In this way, through the plug-in cooperation between the first positioning column 23 and the first positioning hole 112, the positioning of multiple splicing corners in the horizontal plane is realized to ensure the gap size between any two adjacent splicing corners, thereby reducing the process accuracy of the box body 1 itself and improving the positioning efficiency when assembling multiple boxes 1; through the fixed connection between the first fixing member 22 and the first fixing structure 111 in the vertical direction, compared with the connection of adjacent boxes 1 in the horizontal direction, it is convenient to improve the convenience of assembly, thereby improving the assembly efficiency of multiple boxes 1; through the first surface of the first connecting member 2 to limit the multiple splicing angles, the discontinuity of the multiple splicing angles in the vertical direction is reduced or even avoided, so as to ensure the assembly effect of the multiple splicing angles, and then ensure the assembly flatness of the multiple boxes 1.

[0060] The number of splicing angles included in each first splicing area 11 formed by a plurality of boxes 1 may be the same. For example, the LED light box 10 is formed by splicing two boxes 1, which form two first splicing areas 11 after splicing, and each first splicing area 11 includes two splicing angles; or the number of splicing angles included in each first splicing area 11 formed by a plurality of boxes 1 is not the same. For example, the LED light box 10 is formed by splicing four boxes 1, which form five first splicing areas 11 after splicing, and a first splicing area 11 located at the center of the LED light box 10 includes four splicing angles, and the four first splicing areas 11 located at the side of the LED light box 10 each include two splicing angles. In addition, the horizontal plane mentioned above can be a plane formed by the length direction and the width direction of the box 1, and the vertical direction can be the height direction of the box 1.

[0061] In some embodiments, the box body 1 is a structure with one side open in the height direction, that is, Figure 4 As shown, the box body 1 includes a bottom plate 13 and a side plate 14 . The side plate 14 is a cylindrical structure, and one side edge of the side plate 14 is fixedly connected to the edge of the bottom plate 13 to enclose a receiving space through the bottom plate 13 and the side plate 14 .

[0062] In some embodiments, Figure 3 and Figure 4 As shown, a plurality of assembly columns 132 distributed in an array are arranged in the accommodation space surrounded by the bottom plate 13 and the side plate 14. The end faces of the plurality of assembly columns 132 are coplanar. The plurality of assembly columns 132 are used to install the light board to ensure the flatness of the light board after assembly.

[0063] In order to prevent the first connecting plate 21 from interfering with the fixing of the lamp board on the plurality of mounting posts 132 , the end surfaces of the mounting posts 132 protrude from the second surface of the first connecting plate 21 .

[0064] The lamp panel and the mounting column 132 may be fixed by magnetic attraction, that is, Figure 4 As shown, the end surface of the assembly column 132 has a first magnetic member 133, so that the lamp board can be fixed by magnetic attraction between the first magnetic member 133 and the magnetic member on the lamp board.

[0065] In some embodiments, Figure 3 As shown, the LED light box 10 also includes a plurality of interface adapter boards 4, which correspond one-to-one to the plurality of boxes 1, and each interface adapter board 4 is installed in the accommodating space of the corresponding box 1. The interface adapter board 4 is used to be electrically connected to the light board to convert the received display signals such as text, graphics, images, animations, videos, etc. into control signals for controlling the light board to light up, and then control the light board to display based on the control signal.

[0066] Among them, Figure 3As shown, the input end of the interface adapter board 4 is connected to a power module 41, and the output end of the interface adapter board 4 has multiple adapters 42, each of which is connected to a light board, so that the received display signal is transmitted to each light board through the adapter 42. In addition, for the interface adapter boards 4 fixed on multiple boxes 1, as shown in FIG. Figure 3 As shown, the interface adapter board 4 further includes a serial interface 43 , and a plurality of interface adapter boards 4 are connected in series via the serial interface 43 , so as to realize synchronization of signals between the plurality of interface adapter boards 4 .

[0067] In some embodiments, when the positioning of multiple splicing angles at the first splicing area 11 is achieved by the cooperation between the first positioning column 23 and the first positioning hole 112, the first positioning column 23 and the first positioning hole 112 may be an interference fit to avoid the splicing angle and the first connecting plate 21 from rotating relative to each other after the first positioning column 23 is inserted into the first positioning hole 112; the cross-sections of the first positioning column 23 and the first positioning hole 112 may be polygonal (such as rectangular, triangular, etc.) or elliptical to avoid the splicing angle and the first connecting plate 21 from rotating relative to each other after the first positioning column 23 is inserted into the first positioning hole 112; the first surface of the first connecting plate 21 may have multiple first positioning columns 23 corresponding to each splicing angle, and accordingly, each splicing angle has multiple first positioning holes 112, so that the splicing angle and the first connecting plate 21 are prevented from rotating relative to each other by the plug-in cooperation between the multiple first positioning columns 23 and the multiple first positioning holes 112 on one splicing angle.

[0068] It should be noted that, in order to avoid relative rotation between the splicing angle and the first connecting plate 21, any one of the above three methods can be adopted, or a combination of any two of the above three methods can be adopted, and the disclosed embodiment does not limit this. For example, the cross-sections of the first positioning column 23 on the first connecting plate 21 and the corresponding first positioning hole 112 are both rectangular, and the first positioning column 23 and the corresponding first positioning hole 112 are interference fit.

[0069] In addition, combined with the above-mentioned box 1 structure, it can be as follows Figure 4 and Figure 6 As shown, the end face of the corner of the side plate 14 (i.e., the surface facing away from the bottom plate 13) has a first positioning hole 112 to save the accommodation space surrounded by the bottom plate 13 and the side plate 14; or the corner of the bottom plate 13 facing the side plate 14 is provided with a first positioning rod, and the end face of the first positioning rod has a first positioning hole 112. In the case where the splicing corner has multiple first positioning holes 112, it can be achieved by any of the above two methods, or by a combination of the above two methods, which is not limited in the embodiments of the present disclosure.

[0070] In some embodiments, the first fixing member 22 cooperates with the first fixing structure 111 to limit the first connecting member 2 at the corresponding first splicing area 11, which can be as follows: Figure 4 and Figure 6 As shown, the first fixing structure 111 is a threaded hole, and the first fixing member 22 is a fixing bolt. At this time, the fixing bolt passes through the first connecting plate 21 and is tightened in the threaded hole to achieve a fixed connection between the first connecting member 2 and multiple splicing angles at the splicing location; the first fixing structure 111 and the first fixing member 22 may be magnetic members, the first fixing structure 111 is fixed at the splicing angle, and the first fixing member 22 is embedded in the first connecting plate 21, so as to achieve a fixed connection between the first connecting plate 21 and multiple splicing angles at the splicing location through the adsorption and fixation of the first fixing structure 111 and the first fixing member 22; the first fixing structure 111 may be a limiting card slot, and the first fixing member 22 may be a limiting card hook, and the limiting card hook is fixedly connected to the first connecting plate 21 and is clamped in the limiting card slot to achieve a fixed connection between the first connecting plate 21 and multiple splicing angles at the splicing location.

[0071] In the case where the first fixing member 22 is embedded in the first connecting plate 21, the first fixing member 22 may be embedded inside the first connecting plate 21, or may be embedded on the first surface of the first connecting plate 21, so as to ensure the adsorption strength between the first fixing member 22 and the first fixing structure 111. In addition, the adsorption force between the first fixing member 22 and the first fixing structure 111 may be greater than the gravity of one box body 1, so as to ensure that the multiple first fixing members 22 on the first connecting plate 21 can adsorb the multiple splicing angles to the same plane, so as to reduce or even avoid the discontinuity of the multiple splicing angles.

[0072] Among them, in the case where the first connecting plate 21 is fixed at the corresponding first splicing area 11 by means of clipping, in order to avoid the existence of movable space after the limit hook and the limit slot are assembled, the first connecting member 2 also includes multiple elastic members, and the multiple elastic members correspond one by one to the multiple splicing angles at the first splicing area 11. Each elastic member is squeezed between the first connecting plate 21 and a corresponding splicing angle, so that support is formed by the elastic member to avoid the existence of movable space between the first connecting plate 21 and the splicing angle, affecting the assembly effect of the multiple box bodies 1, especially reducing or avoiding the existence of discontinuity after the multiple box bodies 1 are assembled.

[0073] In addition, in combination with the structure of the box body 1 described above, the corner of the side panel 14 may have a first fixing structure 111 to save the storage space surrounded by the bottom panel 13 and the side panel 14; or the corner of the bottom panel 13 facing the side panel 14 may be provided with a first fixing column 131, and the end face of the first fixing column 131 may have a first fixing structure 111. As for the case where the splicing corner has multiple first fixing structures 111, it can be achieved by any of the above two methods or by a combination of the above two methods, and the embodiments of the present disclosure do not limit this. For example, the first fixing structure 111 is a threaded hole. Figure 6 As shown, a first fixing column 131 is provided at a corner of the bottom plate 13 facing the side plate 14 , and an end surface of the first fixing column 131 has a threaded hole.

[0074] In some embodiments, Figure 5 or Figure 7 As shown, the first connecting plate 21 further has at least one first adjustment hole 26 extending therethrough, and each first adjustment hole 26 exposes the seam between two adjacent splicing corners.

[0075] The first adjustment hole 26 is a threaded hole, so that the adjustment bolt can be screwed into the first adjustment hole 26, and when the end face of the adjustment bolt abuts against two adjacent splicing angles at the same time, it is ensured that there is no step difference between the two adjacent splicing angles.

[0076] For example, the first joint area 11 after the plurality of boxes 1 are joined includes two joint corners, in which case the first connecting plate 21 has a first adjustment hole 26, and the first adjustment hole 26 exposes the seam of the two joint corners; or the first joint area 11 after the plurality of boxes 1 are joined includes four joint corners, in which case Figure 5 or Figure 7 As shown, the first connecting plate 21 has four first adjustment holes 26 , and the four first adjustment holes 26 respectively expose four seams between four splicing corners.

[0077] It should be noted that, in combination with the above, when the first fixing structure 111 is a threaded hole and the first fixing member 22 is a fixing bolt, the step difference between two adjacent splicing angles can be adjusted by adjusting the bolt before the fixing bolt is tightened in the threaded hole.

[0078] In some embodiments, Figure 4 and Figure 7 As shown, the first connecting plate 21 has a plurality of first protrusions 24 located on the second surface; the plurality of first protrusions 24 correspond one-to-one to the plurality of splicing angles, each first protrusion 24 and the corresponding splicing angle have an overlapping area in the height direction of the box body 1, and the end faces of the plurality of first protrusions 24 are coplanar.

[0079] Among them, the end face of each first protrusion 24 can constitute a supporting surface to facilitate supporting the light board assembled on the corresponding box 1. Since the end faces of multiple first protrusions 24 are coplanar, the multiple light boards respectively assembled on the multiple boxes 1 are ensured to be in the same plane, thereby ensuring the assembly effect of the multiple light boards.

[0080] Optionally, the end face of the first protrusion 24 is a CNC machined surface, that is, the first protrusion 24 is a structure obtained by CNC machining to ensure the flatness of the end face of the first protrusion 24, thereby ensuring the flatness of multiple lamp panels respectively assembled on multiple boxes 1.

[0081] Optionally, in combination with the above-mentioned situation that the accommodating space of the box body 1 is provided with a mounting configuration, such as Figure 8 As shown, the joint corner also has an assembly column 132 (not shown in the figure), the first connecting plate 21 also has a through avoidance hole 25, the assembly column 132 passes through the avoidance hole 25, and the first magnetic member 133 protrudes from the second surface of the first connecting plate 21, and the distance between the first magnetic member 133 and the second surface is less than the height of the first protrusion 24. In this way, when the lamp board is adsorbed and fixed on the assembly column 132, it will not interfere with the end surface of the first protrusion 24 supporting the lamp board.

[0082] The distance between the first magnetic member 133 and the second surface of the first connecting plate 21 is the height of the upper surface of the first magnetic member 133 protruding from the second surface of the first connecting plate 21. Of course, in addition to the distance between the first magnetic member 133 and the second surface being less than the height of the first protrusion 24, the distance between the first magnetic member 133 and the second surface can also be equal to the height of the first protrusion 24, as long as the flatness of the multiple light panels after assembly can be guaranteed, and the embodiments of the present disclosure are not limited to this.

[0083] In the embodiment of the present disclosure, combined with the structure of the box body 1 and the setting method of the first positioning hole 112, when the first connecting plate 21 is fixed at the first splicing area 11 of multiple box bodies 1, the first connecting plate 21 can be supported on the side plate 14 of the box body 1, or the first connecting plate 21 can be supported on the first positioning rod set on the bottom plate 13. The embodiment of the present disclosure is not limited to this.

[0084] When the first connecting plate 21 is supported on the side plate 14 of the box body 1, it can be directly supported on the end surface of the corner of the side plate 14, or it can be supported on the side plate 14. Figure 6 and Figure 8 As shown, the corners of the side panels 14 of the box body 1 have notches 141, that is, multiple joint corners have notches 141, and the first surface of the first connecting plate 21 is supported on the bottom surfaces of the multiple notches 141. In this way, by setting the notches 141 on the joint corners, it is convenient to reduce the fixed height of the first connecting plate 21, thereby reducing the overall height of the LED light box 10, which is beneficial to the thinning of the display panel.

[0085] In addition, the multiple side surfaces of the first connecting plate 21 can respectively abut against the side surfaces of each notch 141 to limit the position of the first connecting plate 21, thereby pre-fixing the first connecting plate 21 during assembly. For example, the side surface of the first connecting plate 21 can be an arc surface with a middle portion concave toward the center, and the middle portion of the arc surface abuts against the side surface of the notch 141.

[0086] In some embodiments, Figure 3 and Fig. 9 As shown, multiple boxes 1 can form at least one second splicing area 12 after splicing. The LED light box 10 also includes at least one second connecting member 3, each second connecting member 3 includes a second connecting plate 31 and multiple second fixing members (not shown in the figure), and at least one second connecting member 3 corresponds one-to-one to at least one second splicing area 12.

[0087] Among them, each second splicing area 12 includes two splicing edges, and each splicing edge has a second fixing structure and a second positioning hole; the second connecting plate 31 has a third surface and a fourth surface, and a plurality of positioning columns located on the third surface, a plurality of second fixing members correspond one-to-one to the plurality of second fixing structures of the two splicing edges, and a plurality of second positioning columns correspond one-to-one to the plurality of second positioning holes of the two splicing edges; the third surface of the second connecting plate 31 covers a plurality of splicing edges corresponding to the second splicing area 12, a plurality of second positioning columns are respectively located in the second positioning holes on the plurality of splicing edges, a plurality of second fixing members are respectively fixedly connected to the second fixing structures on the plurality of splicing edges, and the second connecting plate 31 is fixed to the plurality of splicing edges.

[0088] In this way, by fixing the second connecting plate 31 on multiple splicing edges, not only can the stability of the multiple boxes 1 after assembly be guaranteed, but also the gap between two adjacent splicing edges and the height difference between the two splicing edges can be limited to further ensure the flatness of the multiple boxes 1 after assembly.

[0089] Among them, the assembly method of the second connecting plate 31 on multiple splicing edges can refer to the assembly method of the first connecting plate 21 on multiple splicing corners described above. Specifically, the setting method of the second positioning hole on the splicing edge can refer to the setting of the first positioning hole 112 on the splicing corner described above.

[0091] It should be noted that the structure of the first connecting plate 21 and the structure of the second connecting plate 31 may be completely the same, or they may be different, and the difference is the number of positioning posts on the second connecting plate 31. The embodiments of the present disclosure are not limited to this.

[0092] In some embodiments, Fig. 9 As shown, the second connecting plate 31 has four second protrusions 32 located on the second surface; every two second protrusions 32 correspond to a splicing edge, and the two second protrusions 32 and the corresponding splicing edges have an overlapping area in the height direction of the box body 1, and the end faces of the four second protrusions 32 are coplanar.

[0093] Among them, the processing method of the second protrusion 32 and the support of the end face of the second protrusion 32 to the light board can refer to the processing method of the first protrusion 24 and the support of the end face of the first protrusion 24 to the light board described above, and the embodiments of the present disclosure are not limited to this.

[0094] In some embodiments, Fig. 9 As shown, the second connecting plate 31 further has at least one second adjustment hole 33 extending therethrough, and each second adjustment hole 33 exposes the seams of two adjacent splicing edges.

[0095] Among them, the specific process and timing of adjusting the break difference between two adjacent splicing edges through the second adjustment hole 33 on the second connecting plate 31 can refer to the process and timing of adjusting the break difference between two adjacent splicing angles through the first adjustment hole 26 on the first connecting plate 21 described above, and the embodiments of the present disclosure do not limit this.

[0096] In some embodiments, the outer side wall of the box body 1 is provided with a second magnetic member, and the second magnetic members on two adjacent boxes 1 are adsorbed and fixed.

[0097] Among them, in combination with the above-mentioned box body 1 structure, that is, the outer wall of the side panel 14 of the box body 1 is provided with a second magnetic part, so that the second magnetic part on the box body 1 can be used to achieve pre-fixation when multiple boxes 1 are spliced, thereby facilitating improving the fixing efficiency of the first connecting plate 21 at multiple splicing corners and the fixing efficiency of the second connecting plate 31 at multiple splicing edges.

[0098] In some embodiments, Fig.10As shown, the LED light box 10 further includes a locking bolt 5; the box body 1 includes a side panel 14, and of two adjacent boxes 1, the side panel 14 of one box body 1 has a through hole 142, and the side panel 14 of the other box body 1 has a locking hole 143, and the locking bolt 5 passes through the through hole 142 and is screwed into the locking hole 143. In this way, when multiple boxes 1 are spliced ​​and assembled by the first connecting member 2 or the first connecting member 2 and the second connecting member 3 described above, the two adjacent boxes 1 can be further fixed by the locking bolt 5, thereby further ensuring the stability of the multiple boxes 1 after splicing.

[0099] The through hole 142 on the side plate 14 of the box body 1 may be a round hole or an oblong hole, so as to facilitate the assembly and fixation of the locking bolt 5 after ensuring the flatness of the assembled multiple boxes 1.

Since the gap size and flatness between the plurality of boxes 1 are ensured when the plurality of boxes 1 are assembled, the gap size and flatness between the plurality of light boards after being fixed are ensured, thereby ensuring the effect of the display panel.

[0102] The embodiment of the present disclosure further provides a display device, comprising the display panel described above. In combination with the display panel described above, the display effect of the display device is ensured.
