Description

Technical Field

[0001] The invention relates to the technical field of LED screens, and in particular to a digital building material structure that combines a building board and an LED decorative screen. Background Art

[0002] The existing LED screen is composed of many modular modules. The on-site assembly and debugging circuit is very complicated, and professional personnel are required to install and debug. The power supply and receiving card are directly behind the screen. There are module brackets and boxes behind the LED modules. The required structural thickness is relatively large. When maintaining, it is necessary to disassemble and maintain from the front of the LED module or from the back of the LED module. In terms of installation structure, it cannot be unified with the installation structure of various panels in the building decoration industry, and regular installation personnel of the building decoration construction team cannot perform installation and debugging. The bracket and the back of the LED module lamp bead are only supported by the frame. The force impact ability of the LED is very poor. Actions such as slapping will cause various faults such as chip desoldering. It is even more impossible to use it as a ground screen. When the screen surface is decorated, some machines such as vacuum laminating machines and laminating machines will cause the LED module to burst and cannot be used. In addition, the color of the existing LED screen is black, and a few are white. It is difficult to integrate with the surrounding decorative environment. There is a lack of decorative surfaces of various materials and colors, so the screen surface is granular lamp beads, which cannot be waterproof and resist external force impact, and is easy to damage.

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The embodiment of the present invention provides a digital building material structure combining a building board and an LED decorative screen, comprising:

[0028] A plurality of LED modules, a mounting plate, an adapter plate and a decorative surface; the mounting plate includes a mounting surface, and the plurality of LED modules are fixedly mounted on the mounting surface along the length direction of the mounting plate; the adapter plate is fixedly connected to the end of the mounting plate; the receiving cards and driving power supplies corresponding to the plurality of LED modules are assembled at the corresponding ends of the mounting plate through the adapter plate, and the decorative surface covers the lamp bead surfaces of the plurality of LED modules.

[0029] In this embodiment, by fixing multiple LED modules on the mounting surface along the length direction of the mounting plate, on the one hand, the size of the mounting plate can be adapted to the building plate, so that the LED screen conforms to the assembled installation method of decoration construction; on the other hand, the box design of the original LED screen module is cancelled, the structural strength of the LED screen is improved, so that it can be used as a ground screen, and the structural strength can withstand the pressure of machines such as vacuum laminating machines or laminating machines during later processing. Using the mounting plate as a base to install multiple LED modules can ensure the flatness of the LED screen, so that the LED screen lamp bead surface can adapt to more materials and colors of decorative surfaces, and the LED screen is packaged to improve the waterproof, dustproof and impact resistance of the LED screen. Furthermore, the adapter plate set at the end of the mounting plate is used to collect and store electronic components such as receiving cards and drive power supplies, which simplifies the circuit of the LED screen and provides a mode that can be maintained up and down, making maintenance and replacement more convenient.

[0030] Furthermore, LED modules that match the standard size of the building decoration industry board are customized. The module uses a PCB board with 2 layers, 4 layers, and 6 layers. The electronic components include row tube chips, driver chips, lamp beads, resistors, and capacitors. The LED module is designed in a long strip along the length of the board, canceling the traditional LED cabinet design. PVC foam boards, glass fiber honeycomb boards, aluminum honeycomb boards, and other boards are used. The holes of the electronic components corresponding to the modules are engraved by an engraving machine. The board and several modules are assembled together by screws or lamination to form an LED screen digital building material structure that is consistent with the building decoration board. After several modules are compounded with the board, the module signal lines are concentrated together through the adapter board. There is only one power cord and one network cable on the upper and lower parts of the whole board, which makes the line simple and easy to install. You only need to connect the power cord and the network cable separately. After installing on the wall, the driving power supply and receiving card and other vulnerable electronic components are set and maintained at the upper and lower ends of the LED screen. Use release film to surround the edge, pour epoxy resin, polyurethane resin or other transparent resin on the surface of the lamp bead until it is flush with the upper edge of the release film, and self-level to obtain a smooth whole board effect on the surface of the lamp bead. Use a vacuum laminating machine to cover the surface of the lamp bead that has been poured with epoxy resin with veneer, decorative PVC film, metal mesh and other decorative materials to obtain the corresponding decorative appearance. Use the spraying method to spray various decorative paints or coatings on the surface of the lamp bead that has been poured with epoxy resin to obtain various spray-coated decorative panels. Use the lamination bonding method to use transparent structural glue or epoxy resin to stick transparent ultra-thin stone on the surface of the lamp bead that has been poured with epoxy resin to obtain stone decorative panel materials.

[0031] In some embodiments, the mounting plate has a first end and a second end, wherein the first end and the second end are relatively distributed; the number of the adapter plates is one, and the one adapter plate is arranged at the first end or the second end; the number of the adapter plates is two, and the two adapter plates are respectively arranged at the first end and the second end.

[0032] It should be noted that the adapter board is designed as a horizontal strip. The adapter board is equipped with several simple bulls that are horizontally connected to the male and female heads of the module simple bulls one by one. Each adapter board is equipped with a receiving card, and the width of the adapter board is determined by the number of horizontal modules that the receiving card can carry. Because the receiving card has a limited capacity to carry a number of lamp beads, when the pixel density of the composite board LED screen is too high, the number of lamp beads within the length of the board exceeds the carrying capacity of the receiving card, so it is necessary to place adapter boards at both ends of the composite board LED screen.

[0033] When the number of the adapter plate is one, the LED modules are installed in sequence from one end of the adapter plate.

[0034] In this embodiment, the design of the composite board LED module and the connection between the modules include the following methods:

[0035] like Figure 1 As shown, the composite board LED module only needs one type of module to be arranged in order from one end of the adapter board. Figure 2 As shown, when a composite board LED screen with a length that is not an integral multiple of the LED module is required, the composite board LED screen of the required length can be obtained by horizontally cutting the LED module farthest from the adapter plate.

[0036] Specifically, depending on the usage environment, there are two ways to connect modules:

[0037] Connection method 1, such as Figure 3 As shown, the A, B, and C modules are provided with cable jacks at both ends vertically, and the D module is provided with a cable jack at the bottom, but no cable jack is required at the top. The signal is connected by the cable of the receiving card adapter board and input into the A module through the cable jack at the bottom of the A module. The adjacent cable jacks between the A, B, C, and D modules are connected through the cable for signal transmission. Figure 4 As shown, a power input port is set at the lower end of the A module to connect to the driving power supply. The power inputs the current through the power input port at the lower end of the A module, and then the current is transmitted by the cables connected between the A, B, C, and D modules.

[0038] It should be noted that this connection method is suitable for connecting the LED module to the plate with screws. When repairing the LED module, remove the screws from the front of the screen, unplug the connector and the power socket, and then remove the LED module for repair.

[0039] Connection method 2: Set positive and negative pads, scan line pads, clock signal pads, data transmission line pads and four-bit signal line pads at the upper and lower ends of the module. Set a cable clamp at the vertical lower end of module A, and no cable clamp is required for other modules. The adjacent pads on both sides of modules A, B, C, and D are welded one by one, such as Figure 5 As shown, the signal is connected by the receiving card adapter board cable and input into the A module through the cable gland at the lower end of the A module. The A, B, C, and D modules are connected through corresponding welding pads for signal transmission. A power input port is set at the lower end of the A module to connect with the driving power supply. The power supply inputs the current through the power input port at the lower end of the A module, and then the current is transmitted through the positive and negative electrode pads welded and connected between the A, B, C, and D modules.

[0040] It should be noted that the second connection method has a simple circuit, the LED module and the board are more tightly combined, and the structural strength is greater, which is suitable for the entire composite board LED screen to be decorated by a machine later.

[0041] In some embodiments, when the number of the adapter plates is two, the adapter plates are installed at both ends of the mounting plate, and the mounting plate includes a first LED module area, a second LED module area, a third LED module area and a fourth LED module area, the circuit electronic components of the first LED module area and the second LED module area are arranged in a mirror image, and the circuit electronic components of the third LED module area and the fourth LED module area are arranged in a mirror image; the arrangement and distribution of the circuit electronic components outside the wiring harness in the first LED module area and the third LED module area are consistent, and the arrangement and distribution of the circuit electronic components outside the wiring harness in the second LED module area and the fourth LED module area are consistent.

[0042] In this embodiment, if Figure 6 As shown, the composite board LED modules are divided into four types: A, B, C, and D. Among them, the A module corresponds to the first LED module area, the B module corresponds to the third LED module area, the C module corresponds to the fourth LED module area, and the D module corresponds to the second LED module area. The screen composed of the four modules A, B, C, and D can ensure that the left-right or up-down arrangement order of the red, green, and blue wafers in the lamp beads is consistent, ensuring that there is no color difference in the screen.

[0043] It should be noted that, depending on the usage environment, there are two ways to connect modules:

[0044] Connection method 1, such as Figure 6 As shown, the A module is provided with cable jacks at both ends vertically. The B module is provided with cable jacks at the upper end vertically, and the lower end jacks do not need to be provided. The D module is provided with cable jacks at both ends vertically. The C module is provided with cable jacks at the lower end vertically, and the upper end jacks do not need to be provided. Therefore, the PCB boards of the A module and the B module are the same, and the PCB boards of the D module and the C module are the same. It is more convenient to produce the screen composed of two PCB boards. The A module signal is input through the upper end jack, and is output to the B module from the lower end jack of the A module through the connecting cable. The D module signal is input through the lower end jack, and is output to the C module from the upper end jack of the D module through the connecting cable. The power input ports are respectively provided at the upper end of the A module and the lower end of the D module. The power input ports of the A and D modules are respectively connected to the driving power supply, and the power supply inputs the current through the upper end power input port of the A module, and the current passes through the circuit in the PCB board of the A module and is output to the B module from the lower end jack of the A module through the connecting cable. The power supply inputs the current through the power input port at the lower end of the D module. The current passes through the circuit inside the D module PCB board and is output to the C module through the connecting cable from the upper end of the D module.

[0045] It should be noted that the above-mentioned connection method 1 is applicable to the LED module connected to the plate by screws. When repairing the LED module, the screws can be removed from the front of the screen, and the connector and power socket can be unplugged to remove the LED module for repair.

[0046] Connection method two: positive and negative electrode pads, scan line pads, clock signal pads, data transmission line pads and four-bit signal line pads are set at the upper and lower ends of the module. A cable jack is set at the vertical upper end of module A, and no jack is required at the lower end. No jack is set for modules B and C, and a cable jack is set at the vertical lower end of module D, and no jack is required at the upper end. The pads on both sides of the lower end of module A and the upper end of module B are welded one by one, the pads on the lower end of module C and the pads on both sides of the upper end of module D are welded one by one, and there is no welding between modules B and C. In this way, the PCB boards of modules A and B are the same, and the PCB boards of modules D and C are the same. The screen is composed of two PCB boards, which is more convenient for production.

[0047] like Figure 7 As shown, the signal of module A is input through the upper end of the simple bull, and is output to module B from the pad welded between the lower end of module A and the upper end of module B. The signal of module D is input through the lower end of the simple bull, and is output to module C from the pad welded between the upper end of module D and the lower end of module C. Power input ports are respectively provided at the upper end of module A and the lower end of module D. The power input ports of modules A and D are respectively connected to the driving power supply. The power supply inputs the current through the power input port at the upper end of module A, and is output to module B from the pad welded between the lower end of module A and the upper end of module B. The power supply inputs the current through the power input port at the lower end of module D, and is output to module C from the pad welded between the upper end of module D and the lower end of module C.

[0048] It should be noted that the second connection method has a simple circuit, the LED module and the board are more tightly combined, the structural strength is greater, and it is suitable for the entire composite board LED screen to be decorated by a machine later.

[0049] In some embodiments, the LED module includes a lamp bead surface and a component mounting surface, the component mounting surface includes multiple mounting areas, each of the mounting areas is arrayed with a row tube chip and a driver chip along the height direction of the LED module, and the row tube chip and the driver chip are spaced apart from adjacent resistors and capacitors.

[0050] In this embodiment, if Figure 8 As shown, a number of row tube chips and drivers are arranged on the back of the lamp bead surface. The row tube chips and driver chips are evenly arranged in multiple areas along the vertical direction. In this embodiment, the row tube chips and driver chips are evenly arranged in three areas. The row scanning and column scanning circuits designed for the "row tube chip" and "driver chip" in each row chip area can be cut horizontally within the dotted line range without affecting the signal transmission and control near the chip end. Therefore, within the dotted line range, modules of different lengths can be obtained by cutting horizontally according to the center line of the entire row arrangement of the lamp beads. The chip and all adjacent electronic components such as resistors and capacitors are arranged regularly and neatly, which is convenient for smooth compounding with the composite plate structure in the later stage.

[0051] In some embodiments, the thickness of the structure in which the mounting plate and the plurality of LED modules are superimposed is consistent with the size of the building plate; the width of the LED module is an integer multiple of the width of the plate in the construction industry.

[0052] It should be noted that the industry standard for the size of panels in the construction industry is width 1220*length 2440 / 3000mm. The width design of a single LED module of an LED screen can be one tenth, one ninth, one eighth, or other integers of 1220mm. When the width requirement of the composite panel LED screen is less than 1220mm, the corresponding width can be obtained by reducing several modules. When the width requirement of the composite panel LED screen is greater than 1220mm, the corresponding width can be obtained by increasing the number of modules.

[0053] The length of the LED module can be set to 1500mm or 1220mm according to the board standard. Considering the production cost and production process, a shorter LED module should be selected.

[0054] The LED module and the mounting plate can be fixed and bonded by means of screws or glue.

[0055] Furthermore, the entire LED screen with the lamp beads facing upwards is laid flat on a horizontal plane, and a release film is attached to the periphery of the screen with adhesive tape. The thickness of the encapsulation layer obtained through experiments should be 3 / 4 of the distance between the center points of the LED screen lamp beads, and the height difference of the upper edge of the release film above the upper surface of the lamp beads is also 3 / 4 of the distance between the center points of the LED screen lamp beads. Epoxy resin, polyurethane resin and other transparent resin materials are poured on the lamp bead surface of the screen to make it self-leveling, and the height of the pouring surface is flush with the upper edge of the release film. The poured screen is sent into a vacuum box, and the vacuum is drawn to make the resin on the surface of the screen free of bubbles. After the resin is cured, a screen with the entire surface encapsulated with resin can be obtained. Because the entire screen is encapsulated with resin, there will be no bright light seams between the screen modules caused by the resin encapsulation of a single module and then splicing.

[0056] In some embodiments, the decorative surface covers the lamp bead surfaces of the multiple LED modules, and the decorative surface includes a metal mesh decorative surface, a spray decorative surface and a stone decorative surface.

[0057] Different from the selection of surface decoration materials for conventional decorative panel materials, in this embodiment, it is necessary to select film materials of different thicknesses according to the different light transmittances caused by the material and color of the different film materials. The thickness selection range of the surface coating material obtained by the experiment is: the thickness of the veneer is 0.15mm-0.4mm, and the thickness of various stone or wood grain PVC films is 0.1mm-0.25mm. Use a 180-mesh sandpaper grinder to grind the surface of the screen encapsulated with epoxy resin, and spray plasticized vinyl acetate emulsion on the polished resin surface and both sides of the digital building material screen. After the plasticized vinyl acetate emulsion is dry, use a vacuum laminating machine to thermoplastically paste the selected coating material to the screen surface at a temperature of 110 degrees. The digital building materials with veneer applied will be subjected to deep treatment such as paint spraying on the veneer surface.

[0058] Furthermore, metal meshes woven with metal wires of different wire diameters will affect the screen brightness and picture quality. The wire diameter obtained through experiments is selected as a woven metal mesh with a wire diameter of 0.15mm to 0.3mm, and the woven wires are tinned copper wire, colored copper wire, stainless steel wire, etc. Use a 180-mesh sandpaper grinder to polish the surface of the screen encapsulated with epoxy resin. Cover the resin surface and both sides of the polished digital building materials screen with transparent hot melt adhesive film and metal mesh in turn, and use a vacuum laminating machine to hot-melt the two materials on the screen surface at 80-110 degrees. By pasting metal mesh decoration on the encapsulated surface of the digital building materials LED screen, a variety of digital building materials LED screens with metal mesh on the surface can be obtained.

[0059] Furthermore, according to the effect of spraying paints of different materials and colors on the light emission of the LED screen, the thickness of the surface paint film is adjusted accordingly. Select paints, coatings, etc. as raw materials for spraying. Use a 320-mesh to 400-mesh sandpaper grinder to grind the screen surface encapsulated with epoxy resin on the encapsulated screen resin surface, and use a spray gun to spray paint or coating on the polished screen resin surface. According to the desired effect, adjust the color and material of the paint or coating. By spraying the encapsulated surface of the digital building material LED screen lamp beads, a digital building material LED screen with a variety of paint film decorative surfaces can be obtained.

[0060] Furthermore, the digital building materials LED screen lamp bead surface pasted composite ultra-thin stone decoration includes two processing methods:

[0061] Method 1: If Fig. 9As shown, choose stone that has been processed to 1mm-5mm. According to the material, light transmittance, color and other factors of different stones, choose the stone thickness between 1mm-5mm. The thickness of the epoxy resin encapsulation layer on the upper surface of the digital building materials LED screen lamp beads is 3 / 4 of the distance from the center point to the center point of adjacent lamp beads on the LED screen minus the thickness of the ultra-thin stone. Use a 180-mesh sandpaper grinder to grind the surface of the screen encapsulated with epoxy resin, and apply epoxy resin glue or transparent structural glue on the polished resin surface. Place the ultra-thin stone on the encapsulation surface of the digital building materials screen lamp beads and put it into the cold press for lamination. After the glue is cured, take it out to obtain a digital building materials LED screen with a variety of translucent stone decorative surfaces.

[0062] Method 2: If Fig.10 As shown, transparent plates such as polycarbonate plates, PC plates or acrylic plates are used as the substrate. The thickness of transparent plates such as polycarbonate plates, PC plates or acrylic plates is 3 / 4 of the distance between the center points of adjacent lamp beads of the LED screen minus the thickness of the ultra-thin stone. First, use epoxy resin, transparent structural glue and other glues to use a cold press to laminate transparent plates such as polycarbonate plates or acrylic plates with ultra-thin stones. Then pour epoxy resin and other transparent glue on the lamp bead surface of the digital building materials LED screen until it is flush with the lamp bead surface, place the plate with the ultra-thin stone and transparent plate on the lamp bead surface of the digital building materials screen and put it into the cold press for lamination. After the glue is cured, take it out to obtain a digital building materials LED screen with a variety of translucent stone decorative surfaces.

[0063] In some embodiments, the distance between the lamp beads of the LED module is set to be equally divided based on the vertical direction of the mounting plate.

[0064] It should be noted that the composite board LED module selects and sets the desired lamp bead spacing along the vertical direction, and adjusts the lamp bead spacing to a length of 750mm. The module's horizontal lamp bead spacing is set to a length of 122mm, which is the closest to the vertical lamp bead spacing. For example, when the module's vertical lamp bead spacing is set to 3.90625mm, 3.90625mm is not a value of 122mm, so 3.8125mm, which is the 32nd value of 122mm closest to 3.90625mm, is selected as the horizontal lamp bead spacing.

[0065] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
