Are you all the bosses having a headache about this? If you want to buy an LED display screen, open the web page and jump out of a bunch of suppliers, the quotations range from thousands to hundreds of thousands, which is dazzling. Don’t worry, let’s break up and chat today, and you will definitely become an expert after listening!

1. Buy online cheaply? More reliable offline?

Nine out of ten customers asked this question wrong! Let’s look at the group comparison table first:

Last year, a catering chain brand suffered a loss: I bought a batch of poster screens on a certain platform for cheap photos, but when I installed it, I found that the interfaces did not match, and finally spent 3 times the shipping fee to return to the factory for renovation. ​ ​All veteran drivers know that you have to look at three points when buying professional equipment: whether there is ISO certification, whether you dare to provide aging reports, and whether you can look at the physical case library​​。

2. The tricks hidden in core parameters

Don’t be fooled by the professional terms that merchants have dumped! Focus on these five indicators:

1. ​​Refresh rate ≥1920Hz​ ​(If you take a slow motion picture of the phone without horizontal lines, you will count)
2. ​​Intelligent brightness adjustment​ ​(Indoor 800-1200cd/m², outdoor 7500cd/m²)
3. ​​Protection level​ ​(It must be anti-salt spray coating used by the seaside)
4. ​​Grayscale​ ​(Fine gradients can be displayed starting at 16 bits)
5. ​​Modular design​ ​(The king is the best way to disassemble and assemble like Lego)

To give a real case: A transparent screen bought in a shopping mall has an 86% transmissivity parameter. After actually installing it, it was found that the bracket blocked 20% of the display area. So,​ ​Depending on the parameters, we need to combine the entire machine design​ ​Just looking at the part data is a hooligan!

3. After-sales service is the touchstone

There is a hidden rule in this line:​ ​Equipment costs only account for 30% of the entire life cycle cost​ ​! Teach you three tricks to identify the authenticity and false service:

• Let sales video connect technicians
• Requires viewing repair orders for the last three months
• Test call customer service at 2 a.m.

A bar owner was smart: when buying a dance floor tiles screen, he asked the manufacturer to write the "2-hour response" into the contract. When it really went wrong, the technician came with a backup module to take a taxi. This​ ​24-hour technical response + full process solution​ ​It is the real guarantee.

4. How to break the price fog?

Remember this formula: Reasonable budget = (display area × unit price) + (annual maintenance fee × service life). Calculate the accounts for everyone:

Have you seen it clearly? The average annual cost of mid-range screens per square meter is only 695 yuan, which is cheaper than low-end screens! Especially for long-term display,​ ​Choose equipment that has passed the salt spray test for more than 2000 hours​ ​More cost-effective.

Editor's opinion: Buying an LED display screen is like finding a partner - it is better to live a life than to be beautiful (display effect) (stable and durable). Those who dare to open a 100,000 square meter production base, who can produce installation cases in 110 countries, and are willing to sign a performance guarantee agreement, are truly reliable. Remember, good products can speak by themselves and dare to spread the full process service to you. You won’t be wrong if you choose with your eyes closed!
