For small-pitch LED display installation, the commonly used methods will choose the frame, unit board, cable, power supply, control card, processor, control computer and other materials to assemble the LED display by yourself, then how to assemble the modules into one The entire large LED display screen, and normal use? Winbond Ying Optoelectronics will take you through the installation steps in detail.
1. Make the main frame and frame, select the steel structure material (40*40*1.5mm square tube) according to the CAD drawing of the set size of the LED display screen, and then cut the material to the corresponding size and weld it into a field shape. The error should not be greater than 1mm, refer to the following drawing requirements;
CAD structure design drawing, and welding of the main frame, fix the welded frame on the wall.

2. Install control system: main cable and main network cable wiring; install power supply and control card; control card connection and power connection are fixed; when connecting the wires between the power supply and the power supply, pay attention to the live wire L, the neutral wire N, and the ground wire The sequence and the power cord of the unit board, the red line +5, the black line -5, the corresponding interfaces; the installation is as shown in the figure below

3. Unit board installation: install the LED unit board and cable connection; the unit board is generally installed from bottom to top, from the middle to the two sides, the reason is that the installation from the bottom is mainly to make the horizontal and vertical can be within the normal control range , To avoid too much error leading to rework.

4. Debugging: According to the signal diagram, the corresponding connection cable sequence; during the installation process, install the 5-row unit board and test the power and signal, and solve the problem in time; because the screen is large, it needs to be installed after all The unit board is removed, and the amount of work is large; there will be a button on each control card, which can play red, green, blue, and slashes, and you can confirm whether there is a bad unit board; if it displays normally, you can install it again One set until the installation is complete.
