Like DIY friends, will choose to buy frame, modules, cables, power supplies, control cards and other materials to assemble their own LED screen , then how to assemble modules into a large piece of LED screen? LED display board manufacturers
share steps for assembling LED screens for you.
Calculate the size first: The unit module uses P5 full color module size is 320*160mm, length 15, height 12, this color screen shares 180 module. 320*15=4800mm,160*12=1920mm, net area is 4800mm*1920mm plus 10mm heads (except for stainless steel used to go 2mm, the last module seam is 5-8mm. The top and bottom heads can be left above From the front can not see), the border size is 4810mm * 1930mm.

First, first make a border
Buy 4*4 square steel 4 4*6 square meters from the market, first use 4*4 square steel to make a frame, the size of the big frame is 4850mm*1970mm, because of the small frame The size is the size of the screen, square steel is 40mm, so it is this size. When welding, use a steel square to weld a 90-degree angle as much as possible. The size in the middle is not important. After the Tianzi frame is completed, it begins to weld small square steel on the top. Xiaofang Steel's internal dimensions are 4810mm*1930mm and the middle part is cut into small sections with the remaining 4*4 square steel to facilitate the package of stainless steel.
4*4 and 2*2 square steel
After the small frame is made, the back welding strip is started. The first two plates are welded with the plate. After the size is found, the welding is continued. The back strip is 40mm wide and has a length of about 1980mm. Both ends can be welded well. After welding, the frame (as the back of the frame) can be installed in the hall. Make two angle hooks at the top of the wall.

Second, install the power supply, control card, module
After the shelf is hung, leave a 10mm gap around, because the indoor screen can not be made into a fan box box frame, only relying on the 10mm gap for simple ventilation.
When installing the power supply, connect the two finished power cables first. The 5V output must be positive and negative. If you connect the reverse power output cable, the power cable and the module will smoke at the time. If you also connect the control card, the card will burn. .
Each finished power cord has two connectors so that each module can have four modules. Then the 220V connection, with 2 squared copper wire to string each row on the line, and finally out of the three groups of 220V power line, into a blank open, empty open above a pair of 6 square copper wire. The screen power is about 9 kilowatts, so there is a surplus of 6 square lines.
After the power supply is connected, the control card is installed, and the control card uses five synchronous receiving cards.

Third, the receiving card and module connection
Each card has three columns of modules, a total of 36 modules, so that every three columns hold a card, take the 5V from the nearest power supply to the card for power, pay attention to the positive and negative poles, and then use the network cable to connect the 5 cards together. The network port of the power connector is the input port. On the right is the first card, which is also the head card. The input is the computer's Gigabit Ethernet card, and the output network port is the input port of the second card, and the second card's The output port is connected to the input port of the third card, so that it is up to the last card, the fifth card, and the input is connected to the output of the fourth card. The output port is empty.

The stainless steel edging is used before assembling the mold set. This is just for the sake of good looks and is also required by the installation unit. The stainless steel master has been specifically recruited to measure the size. I estimate that he will increase the size of the steel structure by 5mm. , to facilitate the installation and can be stuck.

Fourth, install the module
After the stainless steel side is buckled, the upper module can be opened. From top to bottom or from bottom to top, the length of the cable is only suitable for the connection between the module and the module. The long line from the control card to the template is to be done by yourself (also can be used to sell the module ) The top and bottom lines are the longest, about 1 meter and a half long. The long line is started below.

If there are tools, the pressure on both ends will be on the line. At last, the fixed clamp is on the back. Many times, because the back line holds the uneven module, it must be cut off when it is installed. When the line is inserted, the red edge is upward, and the arrow of the module is upward. Words with no arrow up, the previous input connects the output behind.
This color screen share 5 cards, a card drag three modules, each card has 12 T75 interface, this screen is also from the top to bottom 12 rows, when a good full, corresponding plug it on it, The bottom of the screen interface marks the OE, but not the red line of the insertion line (this is just the opposite of the single and double color screens). The cable will not burn the module or the card, but only a light on the module. line.

After installing a card with a three-row module, it will be powered on. If there is a problem, it will be solved in time. If you reinstall a group, it will cover this card. It cannot be tested. The control card has a test button above it. If the screen is installed properly, the screen will The red, green, blue, line, field, and point information are displayed one by one. If normal, install the next group until the installation is completed.
