[0002] As we all know, LED display screens made with LED as light source have been widely used by people. LED display screen is a display method that controls semiconductor light emitting diodes. It is generally composed of many light emitting diodes. When working, it relies on the on and off of LED light source to display characters. In specific implementation, it can be used to display text, graphics, images, animations, market conditions, videos, video signals and other information. LED display screens can be used not only in indoor environments but also in outdoor environments. They have advantages that projectors, TV walls and LCD screens cannot match. In practice, it is often necessary to set up a large LED display screen in a specific location to meet people's use requirements. In this case, large LED display screens are assembled from several LED display boxes. In specific applications, several LED display boxes work together with the support of auxiliary hardware equipment and software programs to achieve the purpose of displaying large graphic information.
[0003] like Figure 1 As shown, a traditional LED display box generally includes a box 1, a power box 2 and an LED light board 3, wherein the power box 2 is installed at the central position of the back of the box 1, the LED light board 3 is installed at the front end of the box 1, and the power box 2 is connected to the central position of the back of the LED light board 3. In practice, the power box 2 is provided with a power module, a control module, etc., and the power box 2 provides the power and control signals required for the LED light board 3 to work.
[0004] However, the above-mentioned traditional LED display box still has the following disadvantages when it is used, which are now described as follows.
[0005] The main weight of the traditional LED display cabinet is concentrated on the cabinet 1, and the material cost and production cost of the cabinet 1 account for the vast majority of the overall cost of the product. Limited by the traditional product design concept, the cabinet 1 is an indispensable component of the product. This design method will inevitably greatly increase the production cost of the product.
[0006] In addition, as the distance between the LED light source points on the LED light board gradually decreases, the design method of connecting the power box 2 to the center of the back of the LED light board 3 will significantly increase the local operating temperature of the LED light board 3. This design method will greatly reduce the service life of the product and increase the product failure rate. As mentioned above, this is the main disadvantage of the traditional technology. Summary of the invention
[0007] The technical solution adopted by the present invention is: a method for plugging and displaying an LED display screen, which comprises the following steps:
[0008] Step 1: Set up the plug-in light panel.

[0031] The design idea of the present invention is to completely abandon the structural design of the traditional LED display box, and design the power box as a side-plug power box 100. When the light board is connected to the power box, the side-plug power box 100 is located at one side end of the plug-in light board 10. At the same time, the power module and the control module are all integrated in the side-plug power box 100, and centralized heat dissipation is performed, and the working heat source of the light board is completely separated from the working heat source of the power box, which can significantly improve the overall heat dissipation performance of the product and greatly reduce the production cost of the product.
[0032] In the third step, a plug-in outer frame 20 is arranged on the plug-in lamp panel 10 .
