[0003] In view of this, the present application provides a display screen that can eliminate vertical bright and dark lines and improve the user's visual experience.

[0004] In order to achieve the above object, the present application provides the following technical solutions:

[0005] A display screen includes a bearing bracket and a plurality of display modules. The display modules are set to be strip-shaped.

Detailed implementation manners

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0032] As Figures 1 - 11 shown, an embodiment of the present application provides a display screen, including a carrier bracket 20 and a display module 10. A plurality of display modules 10 are provided and are sequentially assembled on the carrier bracket 20. Specifically, a plurality of mounting positions are provided on the carrier bracket 20, and the plurality of display modules 10 are mounted one-to-one on the plurality of mounting positions and fixed by screws. Here, the number of the display modules 10 can be set to three, four or five.

[0033] Among them, the display module 10 is set to be strip-shaped, and the plurality of display modules 10 are arranged along the width direction of the display module 10. For example, four display modules 10 are provided, and the length of the display surface formed by assembling the four display modules 10 is the length of a single display module 10, and the width of the display surface is the sum of the widths of the four display modules.

[0034] With such a setting, the plurality of display modules 10 are spliced in the same direction, and there is no need to distinguish the left and right directions of the display module 10, which is beneficial to improving the assembly efficiency. Moreover, the plurality of display modules 10 can be arranged in the vertical direction, and only a splicing seam is formed between two adjacent display modules 10. The splicing seam extends in the horizontal direction, and there is no vertical bright and dark line on the display surface formed by the plurality of display modules 10, which is beneficial to improving the visual experience of users.

[0035] It should be noted that according to the research of ergonomics, the visual field range of a person's eyes is a rectangle with a length-width ratio of 16:9, which means that the vertical splicing seam will look more obvious than the horizontal splicing seam and is easier to be detected by the eyes. By eliminating the vertical bright and dark line on the display surface in this solution, the visual experience of users can be improved.

[0036] In a specific solution, the length of the display module 10 is set to 480 - 520 millimeters, and the width of the display module 10 is set to 100 - 150 millimeters. Preferably, the display module 10 is set to a strip structure of 500 * 125 square millimeters. This allows the display module 10 to be applied to a display of 500 * 500 square millimeters. Additionally, as the stroke of the processing equipment increases, the display module 10 can also be made into a strip structure of 1000 * 125 square millimeters. Compared with the square structure of 250 * 250 square millimeters in the prior art, it can be applied to a display of 1000 * 1000 square millimeters. During the assembly process of the display, there is no need to distinguish between left and right, which is convenient for assembly.

[0037] It can be understood that the substrate in the display module 10 is cut from a mother board. Compared with the square structure of 250 * 250 square millimeters, more strip structures of 500 * 125 square millimeters can be cut from this mother board, and the face value of the discarded materials is smaller. Therefore, the substrate utilization rate of the display module 10 in this solution is higher and the cost is lower.

[0038] In this solution, the display module 10 includes a bracket 1 and a light board 2. The bracket 1 is set to a strip structure for carrying the light board 2. The length and width of the bracket 1 are the length and width of the display module 10. Multiple light boards 2 are provided and are all connected to the same side of the bracket 1 for displaying images. Here, the number of light boards 2 can be set to two or three. Among them, the multiple light boards 2 are arranged in sequence along the length direction of the bracket 1, which can reduce the length of a single light board 2. This is not only beneficial to the processing of the light board 2 but also can improve the substrate utilization rate and save costs.

[0039] Moreover, the distance between two adjacent pixel points located on adjacent two light boards 2 is m. These two pixel points are the center distances of two light-emitting chips located on both sides of the splicing seam of adjacent two light boards 2. m is the point distance at the splicing position of adjacent two light boards 2. The distance between two adjacent pixel points located on the same light board 2 is n. These two pixel points are the center distances of two adjacent light-emitting chips located on the same light board 2. n is the point distance on the light board 2. The two pixel points m and n satisfy -3% ≤ (m - n) / n ≤ 3%, that is, the ratio of the difference between m and n to n is less than or equal to 3%, so that the values of m and n are close.

[0040] In a specific solution, when the distance n between two adjacent pixel points located on the same light board 2 is 1.95, that is, when the point distance on the light board 2 is set to 1.95, the distance between two adjacent pixel points located on adjacent two light boards is m = 1.95 ± 1.95 * 3%, that is, the value range of m is 1.8915 - 2.0085 millimeters. In this way, it can be ensured that no bright and dark lines are generated at the splicing seam between adjacent two light boards.

[0041] Since the bright and dark lines on the screen are caused by the slight errors in the dot pitch. For example, if the pitch of the light-emitting chips at the splicing position is too large, it will cause the brightness to dim and form a dark line; if the pitch of the light-emitting chips at the splicing position is too small, it will cause the brightness to brighten and form a bright line. By controlling the difference between m and n within 3%, no bright or dark lines will appear at the splicing seam position on the display module 10, and the display effect is good, which can improve the user experience.

[0042] During processing, either the position of the light-emitting chips on the lamp board can be adjusted, or the distance between two adjacent lamp boards can be adjusted, so that the dot pitch at the splicing seam position of two adjacent lamp boards meets the above requirements. For example, during processing, with the assistance of a special jig, multiple lamp boards 2 can be spliced onto the same bracket 1, which can well control the gap of the splicing seam between two adjacent lamp boards 2. After assembly, check whether there are bright or dark lines at the splicing seam. If there are bright or dark lines, reprocess, thereby ensuring that the produced display module 10 has no bright or dark lines. In this way, when multiple display modules 10 are assembled on the carrier bracket 20, no bright or dark lines will appear between two adjacent lamp boards 2 on the display module 10, and only the splicing seam between two adjacent display modules 10 will be shown due to the assembly error.

[0043] Specifically, two lamp boards 2 are provided and arranged along the length direction of the lamp board 2. For example, a single lamp board 2 is set to 250*125 square millimeters. In this way, the aspect ratio of the display module 10 can be made larger, thereby solving the problem of vertical bright and dark lines on a larger-sized display screen.

[0044] It should be noted that due to the limitation of the travel of the processing equipment and the problem that the larger the size, the greater the precision error, by assembling multiple lamp boards 2 on a bracket 1, the yield rate and processing difficulty can be improved. Of course, when the processing equipment is operating, the number of lamp boards 2 can also be set to one, that is, the display module 10 is processed from one lamp board 2 and one bracket 1.

[0045] In some embodiments, a waterproof coating is applied to the back side of the lamp board 2. Through the waterproof coating, the components of the lamp board 2 can be covered, thereby realizing the waterproofing of the lamp board 2 itself, which is beneficial for use in outdoor scenarios. In addition, a waterproof coating can also be provided at the edge position of the lamp board 2, that is, the waterproof coating covers both the back side and the edge position of the lamp board 2 at the same time, further improving the waterproof effect. Here, the waterproof coating can be set as UV three-proof glue.

[0046] Such as Figure 4 、 8As shown, the bracket 1 is provided with a plurality of hollow holes 11, and the plurality of hollow holes 11 are evenly distributed on the bracket 1 and penetrate the bracket 1 so that the waterproof coating applied on the lamp board 2 is exposed, thereby improving the heat dissipation effect of the lamp board 2. For example, the hollow holes 11 are arranged as strip holes and extend along the length direction of the bracket 1. Specifically, 16 hollow holes 11 are arranged. Since the lamp board 2 itself has a waterproof function, there is no need for the bracket 1 and the lamp board 2 to cooperate in waterproofing, and the bracket 1 only plays the role of supporting and protecting the lamp board 2. In this way, by arranging the hollow holes 11 on the bracket 1, the heat inside the lamp board 2 and the bracket 1 can be directly convected to the outside, thereby improving the heat dissipation effect and waterproof reliability, while also reducing the equipment investment cost and shortening the development cycle of the manufacturing process, and the overall weight of the display module 10 is lighter, which is convenient for installation and transportation.

[0047] A pull ring 13 is provided on the side of the bracket 1 away from the light board 2. When the display module 10 is transported and installed, and when the display module 10 is assembled, the pull ring 13 can drive the bracket 1 to move, which is beneficial to position calibration, improves the accuracy of assembly, and reduces the difficulty of work.

[0048] In some embodiments, an electrical box 30 is provided in the middle of the supporting bracket 20, and the electrical box 30 is used to connect power and signals so that the display module 10 can display according to the connected signals. The electrical box 30 extends along the arrangement direction of the multiple display modules 10, that is, the electrical box 30 extends along the width direction of the display module 10 and connects the multiple display modules 10 at the same time. Since the multiple display modules 10 are arranged in the same direction, only one electrical box 30 is required to achieve the connection of the multiple display modules 10, and the electrical box 30 can be set in the middle of the supporting bracket 20, which is conducive to improving the balance of the structure.

[0049] In order to facilitate the connection between the display module 10 and the electrical box 30, an adapter plate 3 is provided in the middle of the bracket 1. The adapter plate 3 has a first side surface and a second side surface opposite to each other. The first side surface of the adapter plate 3 is close to the bracket 1, and the second side surface of the adapter plate is close to the light board 2. The first side surface of the adapter plate 3 is provided with a main interface 34, and the second side surface of the adapter plate 3 is provided with multiple branch interfaces. Due to the circuit structure on the adapter plate 3, the main interface 34 is connected to the multiple branch interfaces accordingly. Among them, the main interface 34 is plugged into the electrical box 30, and the multiple branch interfaces are respectively connected to the multiple light boards 2. In this way, the power supply and signal can be transferred through the adapter plate 3, so that the multiple light boards 2 can display according to the signal connected to the electrical box 30.

[0050] In a specific solution, the multiple sub-ports on the adapter board 3 include signal ports and power supply ports. The number of signal ports and power supply ports can be set to one and connected to multiple lamp boards 2 simultaneously, or can be set to multiple and connected to multiple lamp boards 2 one-to-one. Each lamp board 2 is connected to at least one signal port and one power supply port to achieve power supply and signal transmission of the lamp board 2 itself.

[0051] As Figure 6 , 10 shown, a potting groove is provided on one side of the bracket 1 close to the lamp board 2. A transfer board 3 and a sealant are arranged in the potting groove. The sealant covers the transfer board 3 and seals the transfer board 3 in the potting groove. Here, the transfer board 3 is fixed to the bracket 1 by screws and is exposed to the outside air, which is prone to the phenomenon of water ingress and corrosion damage. In this solution, by adopting the potting and sealing method, the transfer board 3 is sealed in the potting groove, which can prevent the transfer board 3 from contacting the outside air, is beneficial to improving the service life of the transfer board 3, and improving the structural stability and reliability.

[0052] Among them, in order to connect the main port 34 on the transfer board 3 to the electrical box 30, an opening is provided at the bottom of the potting groove so that the main port 34 on the transfer board 3 extends out.

[0053] In some embodiments, when the transfer board 3 is connected to the bracket 1, the main port 34 on the transfer board 3 protrudes from the bracket 1 in the direction away from the lamp board 2 so that the main port 34 and the electrical box 30 can be connected more stably and reliably.

[0054] Among them, a waterproof structure is provided on the side of the bracket 1 away from the lamp board 2. The waterproof structure surrounds the outer periphery of the main port 34. When the main port 34 of the transfer board 3 is inserted into the electrical box 30, the waterproof structure is also inserted into the electrical box 30. For example, as Figure 3 shown, an electrical interface 50 and a waterproof groove 40 are provided on the electrical box 30. The electrical interface 50 is arranged in the waterproof groove 40. The electrical interface 50 is inserted into the main port 34 of the transfer board 3. At the same time, the waterproof structure is inserted into the waterproof groove 40 of the electrical box 30. Through the insertion and cooperation of the waterproof structure and the waterproof groove 40, the waterproof of the electrical interface 50 and the main port 34 is realized. In this way, by setting the waterproof structure, the stability and reliability of the connection between the display module 10 and the electrical box 30 can be improved.

[0055] In some preferred embodiments, the waterproof structure includes an annular protrusion 12 and a waterproof rubber ring 4. The annular protrusion 12 is provided on the bracket 1 and surrounds the outer periphery of the main interface 34. Specifically, the annular protrusion 12 and the bracket 1 are integrally formed. The waterproof rubber ring 4 is sleeved on the outer periphery of the annular protrusion 12, and the outer wall of the waterproof rubber ring 4 is provided with waterproof lines. When the electrical interface 50 is inserted into the main interface 34 of the adapter board 3, the outer wall of the waterproof rubber ring 4 abuts against the inner wall of the waterproof groove 40. Due to the design of the waterproof lines on the waterproof rubber ring 4, the waterproof and sealing performance between the waterproof rubber ring 4 and the waterproof groove 40 can be better improved.

[0056] The waterproof structure further includes a bayonet 5. The bayonet 5 is snap-fitted inside the annular protrusion 12 and limits the waterproof rubber ring 4 on the outer periphery of the annular protrusion 12. In this way, through the design of the bayonet 5, the waterproof rubber ring 4 can be prevented from detaching from the annular protrusion 12, which is beneficial to realizing multiple pluggings and unpluggings of the display module 10 and the electrical box 30. For example, the bayonet 5 has an outer edge. When the bayonet 5 is snap-fitted with the annular protrusion 12, the outer edge of the bayonet 5 abuts against the waterproof rubber ring 4, so that the waterproof rubber ring 4 abuts between the bracket 1 and the outer edge of the bayonet 5.

[0057] In addition, the waterproof rubber ring 4 can also be fixed on the outer periphery of the annular protrusion 12 in the form of glue or heat melting.

[0058] As Figure 5 shown, an annular groove is provided on the end face of the annular protrusion 12 away from the bracket 1. The waterproof rubber ring 4 has an inner edge, and the inner edge of the waterproof rubber ring 4 is embedded in the annular groove. When the bayonet 5 is snap-fitted with the annular protrusion 12, the outer edge of the bayonet 5 abuts against the inner edge of the waterproof rubber ring 4, so that the inner edge of the waterproof rubber ring 4 is pressed tightly in the annular groove. In this way, the bayonet 5 presses the waterproof rubber ring 4 on the annular protrusion 12, which is beneficial to improving the installation stability of the waterproof rubber ring 4.

[0059] Next, the connection method between the lamp board 2 and the adapter board 3 will be described through two preferred embodiments.

[0060] In the first preferred embodiment, a first wireless module 31 is provided on the signal interface of the adapter board 3, and a second wireless module 21 is provided on the lamp board 2. The first wireless module 31 and the second wireless module 21 are communicatively connected to enable the communication connection between the lamp board 2 and the signal interface. Specifically, the positions of the first wireless module 31 and the second wireless module 21 are opposite. When the lamp board 2 is connected to the bracket 1, the first wireless module 31 and the second wireless module 21 are arranged close to each other. In this way, by using the wireless connection method for signal transmission, the assembly process can be simplified, the use of wires can be reduced, and costs can be saved.

[0061] As Figure 6 、 7As shown in the figure, the power supply interface is provided with an elastic conductive member 32 and an annular seal 33. The annular seal 33 is arranged around the outer periphery of the elastic conductive member 32. A conductive sheet 22 is arranged on the lamp board 2, and the positions of the conductive sheet 22 and the elastic conductive member 32 are opposite. When the lamp board 2 is connected to the bracket 1, the elastic conductive member 32 abuts against the conductive sheet 22 to realize the electrical connection between the lamp board 2 and the power supply interface. At the same time, the annular seal 33 abuts against the lamp board 2 and surrounds the outer periphery of the conductive sheet 22. In this way, the annular seal 33 abuts between the lamp board 2 and the bracket 1, and can realize the sealing of the inner elastic conductive member 32 and the conductive sheet 22, which is beneficial to improving the safety and stability of the power supply connection.

[0062] Specifically, the elastic conductive member 32 is set as a spring seat, the annular seal 33 is set as a sealing sleeve, and the conductive sheet 22 is set as a copper sheet, with a simple structure and convenient processing.

[0063] It should be noted that in combination with the scheme of sealant and waterproof coating, the first wireless module 31 is arranged on the adapter board 3, and the sealant covers and seals the first wireless module 31 and the adapter board 3. The second wireless module 21 is arranged on the back side of the lamp board 2, and the waterproof coating covers the second wireless module 21 and the back side of the lamp board 2. Since the elastic conductive member 32 needs to contact the conductive sheet 22, under the action of the annular seal 33, the sealant does not cover the elastic conductive member 32, and the waterproof coating does not cover the conductive sheet 22.

[0064] In the second preferred scheme, a waterproof joint assembly 6 is arranged on the side of the lamp board 2 close to the bracket 1. The waterproof joint assembly 6 is communicatively connected to the signal interface through a first connecting wire 7, and the waterproof joint is electrically connected to the power supply interface through a second connecting wire 8. In this way, by arranging the waterproof joint assembly 6, the connection end on the lamp board 2 can have a waterproof function to avoid the influence of external water vapor on the signal and power supply transmission on the lamp board 2.

[0065] Among them, the waterproof joint assembly 6 includes a first joint 61 and a second joint 62. The first joint 61 is arranged on the lamp board 2. When the first joint 61 and the second joint 62 are plugged together, the second joint 62 wraps around the first joint 61 and forms a sealing structure around the outer periphery of the first joint 61. In this way, the sealing and waterproof between the first joint 61 and the second joint 62 can be realized by the plugging of the first joint 61 and the second joint 62, with a simple structure and convenient installation.

[0066] In a specific scheme, the sealing structure may include a sealing ring, and the sealing ring is arranged between the outer wall of the first joint 61 and the inner wall of the second joint 62 to seal between the first joint 61 and the second joint 62. The sealing structure may also include a gasket, and the gasket is arranged between the end face of the second joint 62 and the lamp board 2. When the first joint 61 and the second joint 62 are connected, the gasket is clamped between the second joint 62 and the lamp board 2.

[0067] As shown Figure 9 in the figure, the sealing structure includes a sealing rubber ring 63. The sealing rubber ring 63 is sleeved on the outer periphery of the first joint 61, and sealing lines are provided on the outer side wall of the sealing rubber ring 63. When the first joint 61 and the second joint 62 are connected, the sealing rubber ring 63 is clamped between the outer wall of the first joint 61 and the inner wall of the second joint 62.

[0068] In combination with the solution of the waterproof coating, the first joint 61 is connected to the lamp board 2 and exposed outside the waterproof coating. In combination with the solution of the hollow hole 11, the waterproof joint assembly 6 is located in one of the hollow holes 11.

[0069] The basic principles of the present application have been described above in conjunction with specific embodiments. However, it should be noted that the advantages, advantages, effects, etc. mentioned in the present application are only examples and not limitations. It cannot be considered that these advantages, advantages, effects, etc. are essential for each embodiment of the present application.
