Have you also seen those cool LED clothes? It's the most beautiful baby walking on the street! But if you really want to buy it, are you afraid of being cheated? Last year, my buddy spent 8,000 yuan to buy a "high-tech glowing vest", but after washing your hands, water was scrapped... Let's talk about it today, what should this thing be​ ​Where to buy reliable​​？

1. Why can’t you buy reliable goods?

You may not believe it, now 90% of LED wearable devices on the market exist​​Three major hard injuries​​：

1. ​​Battery life​​: It is said that it can be used for 8 hours, but it actually can't last for 3 hours of concerts
2. ​​Touch-controlled mental retardation​​: If your hands are wet on rainy days, you can accidentally trigger your dance
3. ​​No way to repair​​:Who should I fix the screen if it cracks? The merchant has already run away!

Last week, I saw a shopping mall event with my own eyes. The actors danced in a glowing skirt. When they were halfway through, their skirts suddenly turned into "zebra patterns" - half bright and half destroyed, and the scene was so embarrassing. So, you can't just watch promotional videos when buying this thing, you have to watch it​ ​Underlying technology​​！

2. 5 hardcore parameters that experts are looking at

​​Key reminder​​: Don’t believe the "4K resolution" that merchants brag! The wearable screen has a small size, and the spacing below P3 is all rogue. It is recommended to bring a handle​ ​Vernier caliper​​The pixel points are measured on site and the spacing is ≤1.5mm.

Three, three reliable purchasing channels

1. ​​Direct purchase by ODM manufacturers​​
   Suitable for bulk purchase of enterprises, usually starting from 50 pieces. Last year, I ordered 500 luminous bracelets for a music festival. I just need to find them directly.​ ​A large display factory in Shenzhen​​Customized, the unit price has been cut from 238 to 168. But be aware:

   • Must see​​Automatic production line real shot​​
   • Requested​​72-hour aging test report​​

2. ​​Cross-border e-commerce platform​​
   Suitable for personal taste, but the water is the deepest! Teach you three tricks to inspect goods:

   • Let the seller show the video before taking the photo​​Immersion test​​
   • Test immediately after arrival​​Flash​​: The slow motion mode of the mobile phone camera, and the screen has no black bars to pass
   • Check the packaging​​CE/FCC certification code​​, the official website can verify the authenticity

3. ​​Scenario plan dealer​​
   ​If it is for commercial activities, it is highly recommended to find​ ​Suppliers with technical team​​. They can give you:

   • Dynamic content design (such as changing light effects according to music rhythm)
   • Real-time power supply for backup power vehicles
   • On-site engineers on-site support

4. The trick to avoid pits from the blood and tears

1. ​​"The principle of "three no-buy"​​：

   • Don't buy chip brands if you dare not announce
   • Don't buy if the warranty period is less than 2 years
   • Don't buy videos without landing cases

2. ​​"Three must-see process​​：

   • Check the module splicing seams (if you can put A4 paper in, return it if you can put it in)
   • Check the signal stability (see if there is any delay when you walk 20 meters away)
   • Check the heat dissipation performance (touch the heating area after 1 hour of continuous playback)

3. ​​"Third, leave "evidence​​：

   • Keep screenshots of product parameters
   • Keep logistics unboxing video
   • Keep written documents for guarantee commitment

Editor's opinion

After working in the display industry for so many years, I found​​A manufacturer who dares to be a wearable screen has hardcore technology in hand​​. For example, from some factories​ ​Low bright high gray technology​​, can cut the power consumption by half while maintaining 800cd/m² brightness； Some others have been created​ ​Self-healing conductive film​​, slight scratches can heal automatically after one night.

So, next time I see a seller who is so singular, I will just give him three questions:

1. Which chip is used for lamp beads? (Preferred to Taiwan/Japanese original)
2. Does the driver support HDR10+? (If the dynamic contrast is not enough, it will be blurred)
3. Can you demonstrate the quick disassembly and assembly on site? (The authentic product can be replaced in 10 seconds)

Remember, real gold is not afraid of fire refining, and the good screen can withstand the toss and troubles!
