Description

Technical Field

[0001] The utility model relates to a COB module display technology, in particular to a novel COB display screen module adapter board. Background Art

[0002] At present, the design of COB display module has become increasingly mature, and the adapter board needs to be connected to the display screen by a connector. The main body of the adapter board is a PCB substrate made of printed circuit board technology. The COB display module is formed by directly soldering the light-emitting chip on the PCB substrate and then laminating the entire unit module. The adapter board plays the role of electrical connection in this structure. It connects the COB display module to the control system to ensure that signals and power can be transmitted to each LED chip. The COB display module usually contains LED light modules to form pixels, and the bottom contains IC driving components. These modules will be spliced ​​into LED displays of designed size, and the adapter board is one of the key components to achieve this splicing.

[0003] The shape design of the adapter board directly affects the signal transmission distance between the receiving card and the connector. The common adapter board is in the shape of a "U". The existing adapter board adopts the "U" structure to place the receiving card in the upper left corner of the adapter board (such as Figure 1 As shown in the figure, the adapter board with this structural design will increase the distance from the connector to the receiving card, thereby causing serious signal attenuation.

[0004] The utility model patent with the authorization announcement number CN 211062385 U provides a COB-LED module display unit structure, in which the adapter board device adopts SMT surface mounting technology, the adapter board is a PCB substrate made of printed circuit board technology, and is equipped with an LED display control system receiving card. The main function of the LED display control system receiving card in the COB display module is to receive signals from the control system and connect them to the connector to convert them into data signals that can be recognized by the LED display. Since the middle of the adapter board is a hollow design, when the LED display control system receiving card transmits the signal to the LED display through the connector, since the receiving card is at the edge of the adapter board, the distance from some connectors to the receiving card will be very large or very small, resulting in serious signal attenuation or signal interference, which is not conducive to the stable transmission of the signal. Based on this, the existing technology still needs to be improved. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model proposes a novel COB display screen module adapter board, which can at least solve the problem of serious signal attenuation between the receiving card and the connector caused by the shape setting of the existing adapter board.

[0006] The utility model discloses a novel COB display screen module adapter board, comprising: a first board, a second board, an intermediate board, a receiving card and a connector. The second board is arranged in parallel with the first board. The intermediate board is arranged between the first board and the second board, and is connected to the middle of the first board and the second board. The receiving card is arranged on the intermediate board. The connector is arranged on the first board and the second board.

[0007] In some embodiments, the receiving card is disposed in the center of the middle board, so that the distances from the receiving card to the connectors at both ends of the first board and at both ends of the second board are the same, thus maintaining overall stability of the signal output.

[0008] In some embodiments, the connectors are evenly spaced on the first board and the second board to further ensure the stability of signal output.

[0009] In some embodiments, the first plate and the second plate are both rectangular, which makes it easy for multiple adapter plates to be spliced ​​together to fit into the built-in space of the product, helps to optimize layout and wiring, meets signal transmission and heat dissipation requirements, and facilitates installation and maintenance.

[0010] In some embodiments, the overall size of the adapter board is 259 mm*485 mm, which can fit into the product built-in space and meet the requirements of the COB display.

[0011] In some embodiments, the mounting surfaces of the first board, the second board, and the middle board are on the same side, and the receiving card and the connector are arranged on the mounting surface, which can simplify the internal wiring, reduce the crossing and entanglement of cables, and help improve the stability of the signal and reduce electromagnetic interference.

[0012] In some embodiments, an indicating arrow is also provided on the adapter plate. Since it is difficult to quickly determine the installation direction in the design of the I-shaped adapter plate, the operating efficiency can be improved by providing an indicating arrow on the adapter plate.

[0013] In some embodiments, the adapter board is connected to the COB display module without wires through a connector. The use of the adapter board can realize the interconnection between multiple chips, and the interconnection between chip components and circuit boards, thereby improving the integration of the product. The wire-free connection reduces potential failure points, such as loose or damaged wires, thereby improving the stability and reliability of the display. It can simplify the installation process and improve installation efficiency.

[0014] In some embodiments, the connector includes a female connector and a plug-in connector connected to the female connector. The female connector and the plug-in connector are respectively arranged on the COB display screen module and the adapter board. The connection is reliable and the positioning is precise. It is particularly suitable for use in on-site environments that require quick installation and disassembly, so that the appearance accuracy and consistency of the COB display screen module are guaranteed.

[0015] In some embodiments, a network connector and a power connector are also provided on the side of the adapter board. The signals between adjacent COB display screen modules are connected by a network cable through the network connector, and the network cable is connected to the Ethernet for data connection between modules to ensure that the image and video data can be continuously displayed on the display screen. The power connector is connected to the power supply to provide the necessary power for the COB display screen and other components.

[0016] The beneficial effects of the utility model are as follows: compared with the prior art, the utility model arranges the receiving card in the middle of multiple connectors, which greatly shortens the distance between some connectors and the receiving card, and does not cause signal attenuation due to the distance between the receiving card and the connector being too far, which can effectively solve the common interference problem of display screens.

[0022] It should be understood that the embodiments of the present invention shown in the exemplary embodiments are illustrative only. Although only a few embodiments are described in detail in the present invention, it is easy for those skilled in the art to understand that multiple modifications are feasible without actually departing from the teachings of the subject matter of the present invention. Accordingly, all such modifications should be included within the scope of the present invention. Without departing from the gist of the present invention, other replacements, modifications, changes and deletions may be made to the design, operating conditions and parameters of the following exemplary embodiments.

[0023] As mentioned in the background technology above, the inventors realize that the existing circular adapter plate has at least a problem that needs to be further improved in structure. Based on these problems and room for improvement in the prior art, the inventors provide a new COB display module adapter plate in one or more embodiments, which is believed to solve one or more problems in the prior art including the aforementioned problems.

[0024] like Figure 2 As shown, a novel COB display screen module adapter board of the utility model includes a first plate 1, a second plate 2, an intermediate plate 3, a receiving card 4 and a connector 5. The second plate 2 is arranged in parallel with the first plate 1. The intermediate plate 3 is arranged between the first plate 1 and the second plate 2, and is connected to the middle of the first plate 1 and the second plate 2. The hollowed-out portion between the first plate 1 and the second plate 2 is used to install a power supply, and can also play a role in reducing weight and improving heat dissipation. The receiving card 4 is arranged on the intermediate plate 3. The connector 5 is arranged on the first plate 1 and the second plate 2.

[0025] Compared with the prior art, the utility model arranges the receiving card 4 in the middle of multiple connectors 5. Compared with arranging the receiving card 4 at the edge of the adapter plate, the distance between some connectors 5 and the receiving card 4 is greatly shortened, and the signal attenuation caused by the distance between the receiving card 4 and the connector 5 being too far will not occur, which can effectively solve the common interference problem of the display screen.

[0026] In some embodiments, the receiving card 4 is arranged in the center of the middle board 3, so that the distance from the receiving card 4 to the connectors 5 located at both ends of the first board 1 and at both ends of the second board 2 can be the same, and the signal transmission distance will not be too short or too long, thereby maintaining the overall stability of the signal output.

[0027] In some embodiments, the connectors 5 are evenly spaced on the first board 1 and the second board 2, which helps to arrange the lines reasonably, reduce the crossing and entanglement of cables, and help to improve signal stability and reduce electromagnetic interference.

[0028] In some embodiments, the first plate 1 and the second plate 2 are both rectangular, so that the outer contour of the adapter plate is square as a whole. The square adapter plate can be modularly spliced ​​more conveniently to form a seamless and neat LED display screen, which helps to simplify the installation process. When assembling a large display screen, the modules can be more accurately aligned to achieve high-density packaging, thereby improving the performance and reliability of the LED display screen.

[0029] In some embodiments, the overall size of the adapter board is 259mm*485mm, which can fit into the product built-in space and meet the requirements of COB display. In a limited space, the size of the adapter board needs to be carefully designed to maximize the use of available space while ensuring that the components are reasonably laid out to avoid overcrowding, which helps to improve the performance and reliability of the circuit.

[0030] In some embodiments, the mounting surfaces of the first board 1, the second board 2, and the middle board 3 are on the same side, and the receiving card 4 and the connector 5 are arranged on the mounting surface, which can simplify the internal wiring, reduce the crossing and entanglement of cables, and help improve the stability of the signal and reduce electromagnetic interference.

[0031] In some embodiments, an indicator arrow is also provided on the adapter plate. Since it is difficult to quickly determine the installation direction in the design of the I-shaped adapter plate, by providing an indicator arrow on the adapter plate, it is convenient for the installer to quickly locate, which can improve the operation efficiency.

[0032] In some embodiments, the receiving card 4 and the adapter board are connected to the COB display screen module without wires through the connector 5. The use of the adapter board can realize the interconnection between multiple chips, and the interconnection between chip components and circuit boards, thereby improving the integration of the product. The wire-free connection reduces potential failure points, such as loose or damaged wires, thereby improving the stability and reliability of the display screen. It can simplify the installation process and improve installation efficiency.

[0033] In some embodiments, the connector 5 includes a female connector 5 and a plug-in connector 5 plugged into the female connector 5. The female connector 5 and the plug-in connector 5 are respectively arranged on the COB display screen module and the adapter board. The connection is reliable and the positioning is precise. It is particularly suitable for use in on-site environments that require quick installation and disassembly, so that the appearance accuracy and consistency of the COB display screen module are guaranteed.

[0034] In some embodiments, a network connector 5 and a power connector 5 are also provided on the side of the adapter board. The signals between adjacent COB display screen modules are connected by a network cable through the network connector 5, and the network cable is connected to the Ethernet for data connection between modules to ensure that the image and video data can be continuously displayed on the display screen. The power connector 5 is connected to the power supply, wherein the power supply can be set in the gap between the first plate 1 and the second plate 2, or can be set in other positions to provide the necessary power for the COB display screen and other components. Specifically, the connector 5, the network connector 5 and the power connector 5 are all mounted on the adapter board using conductive or non-conductive glue by using SMT surface mounting technology. SMT is an efficient production process that can automatically place and weld components, allowing the use of smaller components and a denser layout, thereby improving production efficiency. By using conductive glue, the electrical connection between the connector 5 and the adapter board can be ensured to be stable and reliable, reducing failures caused by poor connection. Non-conductive glue can prevent moisture and other environmental factors from damaging electrical components, thereby improving product reliability.
