Hey, are you also worried about where to buy LED displays? There is a lot of information on the Internet. Some people say that you have to buy expensive ones to be reliable, while others say that second-hand goods can also be used. Don’t worry, let’s chat about this matter today, and I’m sure you’ll feel confident after reading it.

1. Before buying a display screen, first understand: What kind of screen do you want?

To give a real example - last year, there was a man who ran a gym. He spent a lot of money to buy an indoor screen for the swimming pool, but it was damaged by water in three months. So,​ ​You must first understand the usage scenario​​：

• ​​For outdoor use​ ​: Billboards and stadium fences must be able to withstand the sun and rain.
• ​​For indoor use​ ​: Conference rooms and shopping mall windows focus on high-definition and non-dazzling eyesight.
• ​​special needs​ ​: For example, stage performances must be able to be quickly disassembled and assembled, and store windows must be transparent and beautiful.

Someone asked: "How do I know what parameters to choose?" "Don’t panic, remember these three hard indicators:

1. ​​brightness​ ​: At least 4,000 nits for outdoor use (even if exposed to the midday sun)
2. ​​refresh rate​ ​: 1920Hz upwards (no ripples will appear when shooting videos)
3. ​​Protection level​ ​: IP65 is the basis (dustproof, waterproof and resistant to naughty children throwing coke)

2. How deep are the purchasing channels? These three paths are the safest

A couple of days ago, a lady who owns a convenience store complained to me: "The screen I bought from a certain store could not be found after three months of installation!" "Let’s be honest here:

1. ​​Find the source manufacturer​ ​: Look for a factory that has its own factory with a monthly output of tens of thousands square meters. The quality inspection process in the workshop is similar to that of security inspection, and the entire process from patching to assembly is monitored.
2. ​​local service provider​ ​: If you want to buy a lot (for example, starting with ten screens), look for someone who can include installation and approval, but you have to guard against middlemen making the difference.
3. ​​Online flagship store​ ​: Nowadays, major manufacturers have official website malls, but remember​ ​Outdoor screens must be customized​ ​! Never buy standard sizes, tailor them to fit you

Here’s a little tidbit: The requirements for goods exported to Japan and South Korea are very strict. If they can pass the certification of these countries, you don’t have to worry about the quality. I heard that a Shenzhen company sells 87% of its products in these places, and even the fence screens for the Tokyo Olympics venues are made by them - for a factory of this caliber, you can just buy it with your eyes closed.

3. A heart-wrenching guide to avoiding pitfalls

Last month I encountered a tragic case: a chain restaurant bought a screen for cheap, and it crashed and restarted every day. Customers thought they were putting on a light show! Here are the key points:

• ​​Don’t save money on after-sales service​ ​: Find a technical team that can respond 24 hours a day. If there is a problem at 3 o'clock in the middle of the night, someone can come
• ​​Electricity matching needs to be calculated in advance​ ​: There was a bar that failed to calculate the power and the circuit breaker tripped five times on the opening day.
• ​​Don’t forget the approval procedures​ ​: To install a large screen on a main road, you have to seek approval from the urban management. Some customers did not go through the formalities and were asked to dismantle it within three days of installation.

An expert told me a trick: look at what major projects the manufacturer has done. For example, I have done curved advertising screens in Singapore and transparent window screens in Seoul. This kind of practical experience is much more useful than sales bragging. Especially now many manufacturers offer "full life cycle services", from design to maintenance, which is more considerate than having a wife.

Let me tell you, buying an LED screen is like looking for a partner - you can't just look at the face (appearance), but also the content (quality) and reliability (service). I have seen too many people try to get a bargain and suffer big losses. In the end, they spent enough money to buy two good sets. Remember,​ ​A good screen can last for seven or eight years. The key is to find the right mother-in-law.​ ​! Next time you see a bright advertising screen on the street, you might as well ask which company it comes from. Maybe it is the powerful one we are talking about today?
