Have you encountered this situation? I wanted to make a cool spherical advertising screen for the mall. I searched all over the Internet and found that some manufacturers quoted 20,000 yuan, while some dared to make 200,000 yuan. I wanted to create a LED dance floor for the bar that could trample on it, but the samples I received turned black. Not to mention those who claimed to be able to make a 360-degree circular screen, the picture was distorted like a haha ​​mirror when installed... These bad things are just not finding the right way. Today we will break it apart and talk about where to look for those dazzling LED special-shaped screens?

​​1. The market status is like a kaleidoscope​
The current LED special-shaped screen market is like a novice entering the Digital City for the first time - the screen is waving around. There are those who work in standard square screens to take special orders, there are studios that specialize in customization, and cross-border players who have switched from the building materials industry. The most troublesome thing is that the price difference of the same spherical screen can be three or four times. How deep is this water?

Take the transmittance as an example. In actual testing, products that boast about 86% light transmittance may not even be 70%. In order to save costs, some manufacturers use ordinary aluminum to install the back panel brackets in high humidity beach venues, and it will be rusted in half a year. What’s even more exaggerated is that among the 18 suppliers of the cylindrical screen project at an exhibition last year, 13 of the 18 suppliers provided samples that did not meet the nominal 1920Hz refresh rate.

​​2. You need to look at these hard indicators when choosing a supplier​​

1. ​​Technical precipitation is more substantial than the factory area​: Don’t look at some factories that often say that they have tens of thousands of square meters of production bases. The key is whether there is any independent development of display technology. For example, the low-bright high-gray technology can make the screen not reflective during the daylight of the mall and not dazzling at night. This is the real kung fu
2. ​​Installation cases outperform renderings​​: Providers are required to provide real-life videos, focusing on splicing seams processing. A truly professional team, the arc error of each box can be controlled within ±0.05° when making a curved screen, just like wearing a customized suit on the screen.
3. ​​After-sales response speed must be written into the contract​: Many pitfalls occur three months after installation. A reliable supplier dares to promise a 2-hour response and brings a spare module to the door. This is the real guarantee.

​​3. How to break the price fog​
Here is a real comparison case: a chain bar needs to install 20 dance floor tiles screens. Factory A has a quotation of 180,000 yuan, saying it is military-grade protection, and Factory B has a quotation of 90,000 yuan and promises a three-year warranty. Three months after choosing Factory B, the contacts of the six screens failed and the maintenance fee was 50,000 yuan. Those who chose Factory A are still in use normally after two years.

So don't just look at the numbers on the quotation, you have to calculate these three accounts:

• ​​Invisible cost​: collision and loss during transportation, structural transformation costs during installation
• ​Time Cost​: Loss of site rent and event extension compensation caused by rework
• ​Opportunity Cost​: The harm caused by customer complaints to the brand image caused by inferior screens

​​Self-question time​
Q: Can you buy those spherical screens with a price of 20,000 yuan on the Internet?
A: This is like buying a mobile phone. The price of 1999 may be modified by the display machine. For serious customized spherical screens, the optical structure design fee will account for 20% of the cost, not to mention the specially treated waterproof interface. It is recommended that the manufacturer provide 72-hour continuous playback of the test video

Q: How to judge whether the supplier is really capable?
A: Ask these two questions directly: ① How to deal with temperature difference deformation in your box joints? ②Can you provide a five-year brightness attenuation curve? Professional manufacturers will take out laboratory data, and the bag company will start to hesitate

Q: Is it reliable to find domestic suppliers for overseas projects?
A: This depends on the supplier's global service capabilities. I heard that a company has specially developed a salt spray coating for Southeast Asia, and even the fixing screws are 316 stainless steel. During the acceptance inspection, the local engineer took the vernier caliper to measure the splicing seam, and the result error was 0.02mm smaller than the promised one.

The editor finally said: Finding an LED special-shaped screen supplier is like finding a marriage partner. Just looking at the appearance (display effect) is not enough, but also depends on the family background (technical reserve), personality (service system), and risk resistance (quality control). Those who dare to spread the laboratory data to you and who can write down pixel failure in the contract are the real partners who are worthy of entrusting. Next time you choose a supplier, remember to take someone who knows what you know to go to their workshop for a walk - you can buy machines, but the work you have with the master is not something you can practice in three or two days!
