[0003] Currently, when testing 8K dot-matrix displays, the decoding board and adapter board are integrated on the same PCB board. The PCB board typically uses a 51-pin, 0.5mm pitch surface-mount horizontal socket. This socket needs to be placed horizontally on one side of the PCB, causing interference between the wires and the PCB board, as well as between the wires themselves. This means that when connecting wires between the screen and the PCB board, the wires must be connected strictly from left to right to prevent interference, which greatly reduces testing efficiency and increases testing costs. Summary of the Invention

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation.
[0025] It should be understood that those skilled in the art will recognize that the invention can be implemented without using these specific details. In other instances, known structures and processes will not be described in detail to avoid obscuring the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles disclosed in this application.
[0026] Please see Figure 1 , Figure 1 This is a simplified schematic diagram of an embodiment of a simple and practical testing fixture for an 8K dot screen provided by an embodiment of the present invention. Figure 1 As shown, this embodiment of the invention provides a simple and practical testing fixture for an 8K dot screen, which includes:
[0027] Adapter plate 10, wherein a first socket 101 is provided on the adapter plate 10;
[0028] Decoding board 20, on which a second socket 102 is provided;
[0029] A connecting cable 30, one end of which is electrically connected to the adapter board 10 via the first socket 101, and the other end of which is electrically connected to the decoding board 20 via the second socket 102;
[0030] Both the first socket 101 and the second socket 102 are vertical plug-in surface-mount sockets.
[0031] Specifically, the adapter board 10 and the decoder board 20 are integrated on two separate PCB boards. The PCB board on which the adapter board 10 is located is provided with a vertical plug-in surface mount socket, namely the first socket 101 mentioned in this application. The PCB board on which the decoder board 20 is located is also provided with a vertical plug-in surface mount socket, namely the second socket 102 mentioned in this application. Therefore, when the adapter board 10 and the decoder board 20 are electrically connected, it is only necessary to insert the male connectors at both ends of the connecting wire 30 into the first socket 101 and the second socket 102 respectively to achieve the electrical connection between the decoder board 20 and the adapter board 10.
[0032] In addition, the adapter board 10 needs to be electrically connected to the screen for testing the decoder board 20 in mass production. This eliminates the need for repeated plugging and unplugging of cables between the decoder board 20 and the screen, thus protecting the screen's socket and extending its lifespan. Specifically, when the adapter board 10 is electrically connected to the screen, a third socket is provided on the screen. This third socket is also a vertical plug-in surface mount socket, and the adapter board 10 is connected to the screen via this vertical plug-in surface mount socket.
[0033] It is understood that the adapter board 10 needs to be equipped with one or more first sockets 101 for electrical connection to the decoder board 20 and the screen end respectively; the decoder board 20 can be equipped with one or more second sockets 102 to achieve electrical connection with the adapter board 10; the screen end can be equipped with one or more third sockets to achieve electrical connection with the adapter board 10. The number of vertical plug-in surface mount sockets on the adapter board 10, decoder board 20 and screen end can be set according to actual application, and no specific limitation is made in this embodiment.
[0034] This invention provides a simple and practical testing fixture for 8K dot-matrix displays. By integrating a decoder board 20 and an adapter board 10 onto two separate PCBs, the adapter board 10 has a first socket 101, and the decoder board 20 has a second socket 102. The adapter board 10 and the decoder board 20 are electrically connected via the first socket 101 and the second socket 102. Both the first socket 101 and the second socket 102 are vertical plug-in surface-mount sockets. This eliminates the need to strictly adhere to a left-to-right wiring sequence between the screen and the PCB, solving the technical problem of mutual interference between wires, reducing interference from production line workers during wiring operations, greatly improving testing efficiency, reducing testing costs, and adapting to more structures with high flexibility. Furthermore, the connection between the adapter board 10 and the screen eliminates the need for repeated wire plugging and unplugging during testing of the mass-produced decoder board 20, protecting the screen's sockets and extending the screen's lifespan.
[0035] In some embodiments, the height of the first socket 101 on the adapter plate 10 is less than 10mm, the height of the second socket 102 on the decoder plate 20 is less than 10mm, and the height of the third socket on the screen end is also less than 10mm. The outer shells of the first socket 101, the second socket 102, and the third socket can all be white. At the same time, the first socket 101, the second socket 102, and the third socket are all rectangular buckle-type vertical plug-in patch sockets.
[0036] In some embodiments, the first socket 101 is located at the edge of the adapter board 10; the second socket 102 is located at the edge of the decoder board 20; and the third socket is located at the edge of the screen. The first socket 101 and the second socket 102 are located at the edges to facilitate the insertion and removal of the connecting cable 30 between the adapter board 10 and the decoder board 20, while the convenient location of the third socket also facilitates the insertion and removal of the connecting cable 30 between the screen and the adapter board 10.
[0037] In other embodiments, the adapter board 10 is a two-layer PCB board, and the decoding board 20 is a four-layer PCB board.
[0038] Specifically, the adapter board 10 and the decoder board 20 are not integrated onto a single PCB board. This not only protects the screen from excessive wire plugging and unplugging between the screen and the decoder board 20, but also reduces the number of layers on the PCB board where the adapter board 10 is located, thereby reducing the overall production cost of the device.
[0039] In the specific implementation process, the adapter board 10 uses a multi-pin surface mount soldering method to solder the first socket 101, the decoder board 20 uses a multi-pin surface mount soldering method to solder the second socket 102, and the screen end uses a multi-pin surface mount soldering method to solder the third socket. Specifically, the adapter board 10, decoder board 20, and screen end all use vertical plug-in surface mount sockets, and are soldered using a multi-pin surface mount soldering method. This not only reduces the weight of the entire device and makes it easier to solder than through-hole sockets, but also further improves the stability and reliability of the circuitry on the PCB board.
[0040] In some embodiments, the connecting line 30 can be an FFC flexible flat cable. FFC flexible flat cable, also known as a flexible flat cable, allows for arbitrary selection of the number and spacing of conductors, while also facilitating wiring. It can significantly reduce the size of electronic products, lower production costs, and improve production efficiency, making it ideal for data transmission cables between moving parts and motherboards, between PCBs, and in miniaturized electrical equipment.
[0041] It should be noted that the FFC flexible flat cable mentioned in this application can be flexible cable with various spacings such as 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 1.5mm, 2.0mm, and 2.54mm. The specific specifications can be selected according to the actual situation, and no specific limitation is made in this embodiment.
[0042] In some embodiments, the adapter board 10 is provided with five first sockets 101, and the decoding board 20 is provided with three second sockets 102. The three first sockets 101 are electrically connected to the three second sockets 102 via three connecting wires 30, and the two first sockets 101 are electrically connected to the screen end via two connecting wires 30. Specifically, the screen end is provided with two third sockets, which are connected to the two first sockets 101 on the adapter board 10 via two connecting wires 30 to achieve an electrical connection between the adapter board 10 and the screen end; simultaneously, the remaining three first sockets 101 on the adapter board 10 are connected to the three second sockets 102 on the decoding board 20 via three connecting wires 30 to achieve an electrical connection between the adapter board 10 and the decoding board 20.
