Have you been confused by this incident recently? I want to create a cool advertising screen for the mall, or give the entire stage background for the concert, turn on my phone and search - good guy! There are quotes ranging from 2,000 to 25,000 yuan per square meter, and everyone says they are the benchmark in the industry. How can novices quickly gain fans? No, I said it wrong, how can novices avoid pitfalls quickly? Today we will talk about something real, and you will be able to avoid detours for three years after listening!

1. First, buy a large screen and see the usage scenario. Don’t rush to pay

Two days ago, I encountered something funny and funny: a restaurant owner spent more than 200,000 yuan to install an outdoor screen, but the reflection was severe during the day, and customers couldn't even see the menu price clearly. Here is an iron rule:​Indoor and outdoor demands are very different​! Let me give you a key point:

• ​Indoor screen​Depending on whether the brightness is soft or not (recommended 800-1200cd/m²)
• ​Outdoor screen​You have to withstand the sun and rain (brightness starts at least 4000cd/m²)
• ​Stage rental screen​The focus is on weight and disassembly speed
• ​​Window display screen​The permeability must be considered (don't ask if it's below 80%)

To give a real case: a transparent window screen installed in a convenience store chain maintains a 86% transmissibility during the day to display products normally, and automatically switches to advertising screens at night. The customer flow increased by 17% in three months. This is spending money on the blade!

2. There are many parameter traps that are ridiculous, these three must be fought hard

Nowadays, merchants like to use parameters to bluff people, but veteran drivers understand—​​Effective parameters ≠lab data​! Focus on:

1. ​​Refresh rate requires on-site inspection​​
   Take a slow motion of the phone and shoot it in front of you. If you don’t have horizontal lines, you will be really high-brush. A performance company suffered a loss: the screen marked with a 3840Hz was actually displayed when the camera shot during the actual performance. In the end, it had to be reinstalled if it was compensated for the liquidated damages.

2. ​​The protection level is only counted​
   IP65 is also of different levels. Those used by the beach must be equipped with salt spray coating, while those next to the viaduct must be resistant to vibration. There is a trick: let the manufacturer provide it​Same environment case video​。

3. ​​After-sales service has a big pit​
   Key questions:

   • Is the response time really 24 hours (some say it is 24 hours, but I called in the middle of the night to wait for work)
   • Can the module be replaced separately (the cost difference between full-screen repair and replacement parts)
   • Do you need additional fees for software upgrades?

3. How to break the price fog? Remember this golden formula

Total cost = ​​(Purchase price ÷ estimated service life) + annual maintenance fee​​ . Calculate the accounts for everyone:

Did you see it? The average annual cost of mid-to-high-end screens is the lowest! Especially for long-term demonstrations, don’t be greedy for cheap things.

4. Soul-questioning session: Choose to rent or buy out?

Nine out of ten clients asked this question wrong! The key is​Frequency of useand​Technical iteration speed​：

• Use for more than 200 days per year → Buy out and make a good deal
• Need cutting-edge technology (such as XR virtual shooting) → More flexible rental
• Temporary activities (such as music festivals) → Find a rental screen with "Quick disassembly" function

There is a clothing brand that is smart: the headquarters exhibition hall bought out the 4K high-definition screen, and pop-up stores in various places use revolving and disassembled rental screens, saving more than 600,000 transportation costs in three years.

5. How deep is the water for cross-border procurement?

Nowadays, many people are looking for overseas suppliers. Here are three things to remind you:

1. Confirm whether to bringMulti-country certification​(CE and CCC are the basics)
2. Logistics packaging must be moisture-proof and earthquake-resistant (sea transportation salt spray test report must be read)
3. How to solve the problem of time difference (can technical support respond 24 hours a day)

Last year, a shopping mall in Southeast Asia purchased a fence screen from China. Because it did not have a surge prevention design, three modules were smashed by lightning during the rainy season, and the international freight alone was compensated for more than 50,000 US dollars.

Editor's opinion: Buying a large LED screen is like finding a marriage partner - appearance (display effect) and family background (price) are important, but life depends on whether the temper is in line (system compatibility) and whether it is reliable when you are sick (after-sales maintenance). Those who say "five years of replacement" on their chests should not show you it's true.​Aging test report​; it is better to show off those who boast about "global leading".Installation cases in more than 110 countries​of. Remember, if you are good products, you can speak by yourself, and you dare to spread the entire life cycle service to you, which is really reliable!
