Are you also dazzled by searching for "LED circle screen" online? The novice novice wanted to buy a circular display, but found that some merchants asked for more than 100,000 yuan, while others priced at 20,000 to 30,000 yuan. The price difference was too big! Not to mention those scattered technical parameters, such as P2.5 and P3, it makes people feel hurt. Today, let’s talk about how ordinary people can buy reliable round LED screens, and teach you a few tricks to avoid merchants’ routines.

1. Find out what you want first

A two-day ago, a bar owner asked me to complain and said that he bought a circular screen to install the stage, but the video was always deformed. When I saw it, I saw it, a guy, he bought an ordinary square screen that was used to break it into a curve. Here you need to highlight the key points:​ ​Real circular screen and modified screen are not the same thing​​。

• ​​Depend on the structure​ ​: The modules of the regular round screen are all specially made fan-shaped units, which are as tight as cutting cakes. Those who use square modules to force them, there must be gaps in the corners.
• ​​Ask for parameters​ ​: The minimum refresh rate is 1920Hz, otherwise the video shooting will be scan lines. If used indoors, the brightness must not exceed 1,200 nits, otherwise the guests will be blinded.
• ​​Touch the material​ ​: The aluminum-magnesium alloy box is the correct solution, and the plastic material is used for half a year and is quasi-deformed. Recently, a milk tea shop owner bought a plastic shell screen that was greedy for cheap, but now the surface is wavy.

2. Don't step on these pitfalls

I have a friend who is a shopping mall, and bought a second-hand refurbished screen with a cheap look. As a result, on the day of installation, I found that one-third of the lamp beads were in the color of the lamp beads. Here are three tips to prevent pits:

1. ​​See certification​ ​: CCC certification is the lowest threshold, and only those with CE certification can export. Recently, the customs seized a batch of screens with fake marks, and their waterproof performance is not as good as that of washbasins.
2. ​​Ask about production capacity​ ​: Make sure to choose manufacturers with a monthly output of less than 10,000 yuan. Such factories may not even have a fixed production line. Last year, there was a screen ordered by an internet celebrity restaurant on Double Eleven, and it took three months to deliver it.
3. ​​Trial service​ ​: It is only reliable to dare to promise 24 hours of response. Last time there was a screen problem at an exhibition site. The reliable manufacturer arrived from the next province in two hours with spare parts.

3. What is the difference in price

You must be wondering why some circle screens of the same size sell for 80,000 or 200,000? The secrets are all in these places:

• ​​Light bead quality​ ​: The light decay of using regular chips shall not exceed 5% in 50,000 hours. Some low-priced screens start to grow in half a year"
• ​​Thermal system​ ​: It makes sense that it is expensive with intelligent temperature control. The most exaggerated case I have ever seen is that the screen in a certain bar turned off three times in summer due to poor heat dissipation.
• ​​Splicing accuracy​ ​: After the good screen is installed, the seams of the poor screen can be stuffed into the bank card. There is a cheap screen bought by a real estate company. When the lights are on at night, there are black shadows at the joints.

4. Three questions that Xiaobai must ask

​​Q: How big can a circular screen be made? ​ ​
Now the mainstream diameter can be made from 1 meter to 8 meters, but if it exceeds 5 meters, it must be supported by steel structure. An automobile 4S store made a 6-meter diameter rotary screen, and eight load-bearing columns were used underneath.

​​Q: What should I pay attention to when using outdoors? ​ ​
The waterproof level starts at least IP65, so it is best to choose a power supply with self-test function. Last month, there was a power module with an outdoor screen short circuit in water, and the entire screen burned.

​​Q: Is the later maintenance expensive? ​ ​
The modules of good screens are all front-maintenance designs, and the lamp beads can be replaced without removing the shelf. The most pitiful installation method I have ever seen, changing the block module requires removing the entire ring structure

Buying an LED circular screen is like finding a partner - just looking at a look is easy to suffer, you have to find out the details. Those merchants who openly promise "the lowest price on the entire network" are advised to circumvent it. A truly reliable supplier will instead pull you to confirm the usage scenario and check the installation environment. remember,​ ​When buying a good screen, it hurts so much.； The bargain smiles when buying, and gets crying when repairing​ ​. Next time I see that the quote is ridiculously low, I might as well ask more questions: "The lamp beads on your screen are not weighed by pounds, right? "
