Hey, old man, have you been dazzled by the cool advertising screens all over the streets of Yangshuo recently? Have you ever wondered - are these LED screens all made locally in Yangshuo? Today I’m going to talk a little more truthfully, and I’m sure I’ll make it clear to you!

1. Is there an LED factory in Yangshuo?

Let me tell you the truth first:​ ​Ninety-nine percent of the local LED screens in Yangshuo are shipped from other places.​ ​! Why? Take a look at the karst mountain buns all over the street. It is very difficult to build a large-scale manufacturing industry in this terrain. But don’t worry, if you want to find a reliable manufacturer, you have to go where the industrial chain is concentrated.

Take my experience last year when I helped a B&B owner choose a screen. I originally thought that there were factories near Yangshuo that would save on shipping costs, but I found out after I traveled all over Guilin Industrial Park.——​ ​The truly professional LED manufacturers are all hidden in the Pearl River Delta​ ​! Especially in Shenzhen, the automated production base alone covers an area of ​​tens of thousands of square meters, with a monthly production capacity of 10,000 square meters, which is equivalent to covering 30 standard basketball courts every day!

2. Three golden rules for choosing a factory

Don’t listen to salesmen, remember these three tricks are more effective than anything else:

1. ​​See if the factory is "certified to work""​​：

   • ISO9001 certification is the basic threshold
   • International certifications such as CE and CCC are required (especially if you want to export)
   • Do you dare to show the quality inspection report? Full process inspection records are the real thing

2. ​​"harder than technical parameters""​​：

   • Refresh rate ≥1920Hz (lower than this number, football games will definitely smear)
   • ​​You have to adjust the brightness by yourself​ ​(800-1200nit indoors, 4000-7500nit outdoor is enough)
   • The transparency rate of the transparent screen is at least 86% (don’t let the window become a mosaic)

3. ​​Check whether the service is "one-stop service""​​：

   • 24-hour technical team on call (only equipment that can be deployed in the middle of the night and can provide emergency rescue will count)
   • Warranty period starting from three years (those who dare to promise a pixel failure rate of ≤0.01% are ruthless)

Last month, I ordered a batch of floor tile screens for a bar owner. The manufacturer directly sent an engineer with a humidity detector and even measured the moisture return coefficient of the floor. This is called professional style!

3. How to deal with special needs?

Don’t think that all LED screens have square heads and square brains! Nowadays, there are many manufacturers playing tricks:

• ​​Concert scene​ ​: The aluminum-magnesium-zinc cabinet needs to be disassembled in seconds. It can be disassembled and assembled faster than changing guitar strings.
• ​​stadium fence​ ​: IP65 protection level is standard (still as stable as an old dog in heavy rain)
• ​​shopping mall window​ ​: Transparent screen with 86% light transmittance, no delay in products and advertisements

I remember that there was a scenic spot that was going to have a real-life landscape performance, and the manufacturer suddenly developed a customized model that was anti-fog and anti-salt corrosion. This kind of​ ​Low brightness and high gray technology​ ​Thanks to the blessing of the screen, Sister Liu’s folk songs can still be heard clearly on a foggy day!

4. How to verify the strength of the manufacturer?

Teach you a few tricks to test real gold:

1. Let sales show you​ ​Real-time production monitoring​ ​(Are the robotic arms really working in the workshop?)
2. want​ ​Copy of export declaration form​ ​(You can’t go wrong with a factory that can sell 87% of its products to Japan and South Korea)
3. Ask them for​ ​Three-year failure rate statistics table​ ​(Honest people who dare to show data are reliable)

Last year, a manufacturer boasted that its screen could withstand typhoons, but someone actually took the wind test report to inspect the product - it was blown continuously in a level 12 wind tunnel for 8 hours, and the box connectors did not move at all!

Let me tell you, looking for an LED manufacturer is like looking for a partner. ​ ​Yangshuo may not be the best choice geographically, but those large factories in the Pearl River Delta with a monthly output of over 10,000 square meters are the "honest people" who can really give you a sense of security."​ ​. Next time you see those dazzling screens on Yangshuo West Street, don't forget - they may have come over the mountains in containers, carrying the confidence of 3,000 hours of aging testing in the Shenzhen factory!
