How big can the splicing screen be?


As the name implies, splicing screens are spliced together. If you pay attention to it, you will find splicing screens in many places in life, such as studios, movie theaters, exhibition halls, and even slightly higher-end restaurants. LCD splicing units There are big and small, and the pieces are of different sizes. So the question is, if you want to make a very, very large screen, you may need thousands of LCD splicing units. Can this be achieved? Or how big can the splicing screen be?








multi-screen








In theory, as long as the LCD splicing unit of the same size and brand is used, it can be spliced infinitely, including horizontal or vertical splicing. But the reality is not so perfect, mainly for the following reasons.




1. Weight problem


  


  The current common sizes of splicing units are 46/49/55 inches, etc. The average weight of each piece is about 15-20 kg, which is calculated as 15 kg. If 10,000 pieces are spliced together, the total weight will reach kg, which is 150 tons. This is a very terrifying number. Even if it is transported by a 13-meter trailer (the state stipulates a maximum of 34 tons), it takes 5 vehicles. Then imagine if you put it up and splice it into a large screen, I am afraid that the average ground cannot withstand it. , Let alone the support that can carry the weight of 150 tons, and the problems caused by the lower the screen is squeezed, usually dozens of splicing screens must be checked regularly for this problem, if 10,000, it is almost unimaginable.




2. Line problems


  


  Each splicing unit has 3 wires: power cord, network cable, and high-definition cable. If there are 10,000 splicing units, think about how terrible the wiring problem is. The placement of light materials requires a lot of space, let alone the wiring. , In short, it must be very headache. I’m afraid I don’t even know how many sockets to use! However, the editor believes that if product developers can invent an invisible plug-in serial interface that can be used between each screen without occupying space, the wiring problem will be easily solved. But for now, I can only look forward to it.




3. Signal problem


  


  The splicing screen is actually a large display, and the content it displays is uploaded through the signal processor, which involves the signal transmission problem between the signal source and the splicing screen. Take the 46-inch splicing unit for example, the length is about 1 meter and the height is about 0.6 meters. The length of the 10,000 block is 10,000 meters and the height is 6,000 meters. In the process of signal transmission, a signal amplifier must be installed if it exceeds 30 meters. Over 300 meters, the signal can hardly reach the splicing screen without distortion, so the signal problem may be very difficult to solve.




4. Energy consumption issues.




Take the same 46-inch splicing unit, the power of one piece is about 200 watts, and 10,000 pieces are 2000 kilowatts. In other words, if all lights are on, it will consume 2000 kWh of electricity in one hour. This is actually nothing, more important How much power supply equipment is needed to provide power? This may be very scary, at least the general equipment may be far from being able to withstand this level of power, of course, it may be that the editor has limited knowledge and cannot think of a reasonable solution.




Of course, the above is just a brief explanation of the main problems that you will encounter. To run such a large splicing screen, it is definitely far more than these problems. But I have to say that in reality, dozens of pieces of splicing screen projects are still very common, even hundreds of pieces. What thorny problems have been encountered, and how to solve them one by one, I am afraid that only to ask the installation technicians to know .
