Brothers, have you encountered this situation? I wanted to do a large LED screen to conduct an event, but I searched the Internet. There were so many manufacturers, and the quotations ranged from hundreds to tens of thousands, which made people scratch their heads. Today we will talk about where to buy this LED display screen.

1. Can online procurement really make a bargain?

Let me first talk about a real case: Last year, a shopping mall celebrated its anniversary and bought a P4 screen on an e-commerce platform with a cheap price. As a result, the color difference was found to be serious on the day of installation. The customer service disputed for half a month when returning the product, which delayed the promotion season. So, you have to check these tricks for buying screens online:

• ​​Check the store qualifications​​: Is there any real-life video shot in the factory? Do you dare to open a video inspection factory?
• ​​Check product certification​​: Certification certificates such as CE and CCC must be checked on the spot
• ​​Sample test service​​: All serious manufacturers support sending samples, don’t believe the slander of “just look at pictures”

A friend who was doing wedding complained to me: "The water online is too deep now, and the same link can sell three quality goods. Later, I learned my lesson and asked the manufacturer to send a control card sample directly. I dared to place an order after measuring the grayscale performance. "

2. Gold mines are hidden in offline channels

To be reliable, it depends on the physical channels, but there is more knowledge here. Teach you three tricks to find dealers:

1. ​​Touch the warehouse inventory​​: The real big company is the one who can transfer goods at any time
2. ​​Look at the project case​​: Recent construction videos are required, and special attention is paid to wiring details
3. ​​Test the response speed​​: Called at 8 pm and said you should use it urgently to see if the other party can transfer goods overnight

Last year, I helped my friend choose the stadium fence screen and went to five dealers. Finally, I chose the one and took us directly to the gym they worked with to see the actual installation effect. I took a photometer on the spot and the brightness of 7500cd/m² is steadily meeting the standard. This is the real ability!

3. Hidden benefits from special channels

Do you know? Some procurement channels can save real money:

• ​​Government procurement platform​​: Recent data from Henan government procurement shows that the centralized procurement price is 28% lower than the market price on average
• ​​Direct sales for industry exhibitions​​: In occasions like Shenzhen Optical Expo, manufacturers often recommend "exhibition special prices""
• ​​Trade-in activities​​: Some large factories recycle old screens to pay 30% of the goods

But I want to remind newbies,​​If the account period exceeds 3 months, don't touch it​​. Last year, a 4A company was greedy for the half-year payment period, but the partner ran away and the final payment of 600,000 yuan has not been settled yet.

4. Life and death line in technical parameters

Don't be fooled by sales, remember these​​Hard indicators​​：

• ​​Refresh rate ≥1920Hz​​: The bottom line of shooting videos without flashing screens
• ​​Intelligent brightness adjustment​​: The indoor jump starts at 800, and the outdoors cannot withstand the sun without 4000cd/m².
• ​​Protection level IP65​​: Don't rush to close the screen on rainy days
• ​​Grayscale 16bit​​: The life gate of the sense of layering of the picture

A lesson from blood and tears: a chain of milk tea shops bought non-standard products at a cheap price, but the batter was formed on cloudy days, and finally they had to spend double the money to reinstall. So,​ ​Low bright high gray technology​​It's really a need!

5. Service is the touchstone

It is not scary to have equipment problems, but what is scary is that you can't find someone to take care of it. Reliable channels must be:

• ​​24-hour response​​: Singaporean customers seek help in the middle of the night, domestic engineers provide video guidance
• ​​Full process quality inspection​​: More than 20 inspection processes from chip packaging to finished product shipment
• ​​Localization Service Network​​: Manufacturers set up stations in more than 110 countries, with absolutely strong emergency response capabilities

A boss who advertises a building said: "Now it's better to choose a large factory with 15% more expensive products. Last year, the screen was filled with water during heavy rains. They came with a backup module for two hours. This service is worth the ticket price! "

​​Exclusive data​​: According to industry research, the hidden costs of purchasing LED screens can account for 37% of the total price, including after-sales maintenance, electricity bills and losses and opportunity costs. So, don't just look at the numbers on the quotation——​ ​Choose the right procurement channel and save a new screen in three years​​Not a dream!

Finally, I said something heart-wrenching: This line of water is really deep, but remembering three points is absolutely correct——​​Looking at cases and parameters is more realistic, looking at workshops and brochures, looking at service teams and bargains are more important​​. Next time I want to buy a screen, it is recommended to go directly to the manufacturer's workshop to see if their aging test is really baked for 72 hours, which is more effective than any sales rhetoric!
