Alas, I want to install a large LED screen but I don’t know where to start? Don’t panic! Today we will break it apart and talk about this. Look, now, no matter whether it is shopping malls, shops advertising, or stadiums, LED screens can be seen everywhere. But the question is - where should I buy this thing? How to choose? There are many ways here!
1. Want to buy an LED screen? Have you tried these channels?
1. Find the source manufacturer and discuss it directly
If you have a sufficient budget or very large demand (for example, the entire exterior wall of the shopping mall needs to be installed), it is the most cost-effective to directly find a manufacturer. Nowadays, many major manufacturers have their own official websites and online exhibition halls, and can also watch the prototypes in video. Remember to see theirs ISO CertificationandExport qualifications, manufacturers who can build international markets have higher technical standards.
Give a chestnut: Some manufacturers specializing in overseas markets, 87% of their products are sold to countries such as Japan and South Korea that have high quality requirements. The quality control of such factories is absolutely reliable.
2. Local integrators worry-free
If you can't handle the installation and debugging of these technical tasks, it's right to find a local service provider. They can usually provide One-stop service from design to maintenance, especially in scenarios where special screens or special installation is required. However, you have to pay attention to the after-sales response time, and it is best to choose one with 24-hour technical support.
Focus on: When encountering rental screens that need to be disassembled and installed quickly, remember to look at the box material. The latest aluminum-magnesium-zinc alloy box can be disassembled and installed in 10 square meters in ten minutes for two people!
3. Transparent selection of government procurement platforms
Government units or state-owned enterprises can go to the government procurement mall, and all the parameters and quotations here are clearly clear. Henan Government Procurement Data in 2024 shows that the transaction price of indoor screens with P2.5-P3 specifications is concentrated at 3,800-5,200 yuan/square meter, which can be referenced for this price range.
2. Purchase the five major indicators of King Kong
① The brighter the brighter the better
- Indoor screen: 800-1200cd/m² is enough (too bright will make you dazzling)
- Semi-outdoor: 2000-3500cd/m² (such as shopping mall atrium with canopy)
- All outdoor: Go directly to 4000-7500cd/m² (you can see clearly under the sun)
Pay attention to the parameters: Now high-end screens have intelligent dimming functions, which can automatically adjust the brightness according to ambient light, saving more than 30% of power than fixed brightness.
② The distance between points should be viewed
Here is a shorthand formula: "The smaller the P value, the clearer the wallet, and you need to prepare more." For a common one:
- P1.5-P2 for conference room
- Store window P2.5-P3
- Outdoor advertising P4-P6
Technical control knowledge: Now some manufacturers have developed low brightness and high gray technology. Even if the brightness is adjusted to the lowest level, the color levels are still clear. This kind of screen is especially suitable for long-term viewing.
③ Don't be fooled by refresh rate
- Normal display 1920Hz is enough
- Those who need to shoot live videos must start at 3840Hz
- Film and television production directly up to 7680Hz
Test tips: Use your phone to shoot videos against the screen. If water ripple appears, it means that the refresh rate is not enough.
④ The protection level cannot be adjusted
- Just the indoor screen IP43
- Outdoors must start with IP65 (dust-proof and waterproof spray)
- These places at the beach/construction site require IP68
Real cases: The fenced screen in a certain gymnasium uses IP65 protection and still works normally during typhoon days. The rain flows along the screen and does not enter the interior.
⑤ Energy consumption calculation long-term accounts
Don’t look at the unit price difference of several hundred yuan, electricity bills are long-term expenses. Now the advanced common-yang voltage divider technology can directly reduce power consumption by 50%. Based on 12 hours a day, three years of electricity bill can save a new screen!
3. A guide for newbies to avoid pits
Pit ① Low-price trap
Why do some P3 screens sell for 3,000 and some sell for 6,000? The secret is on the lamp bead!
- Brand lamp beads for regular manufacturers (lifetime from 50,000 hours)
- Miscellaneous brand screens may use refurbished lamp beads (color deteriorates after 1 year)
Pit ② Parameter virtual mark
I will teach you three tricks to check the authenticity:
- Third-party testing report
- On-site brightness meter test
- Check whether the grayscale transition is smooth
Pit ③ After-sales ripping
Two points to focus on:
- Is there any local service outlet
- Is the spare parts inventory sufficient (a good screen is bad and the lamp beads will not affect the use, but if there is no spare parts, you can only dry them).
4. How to choose these scenarios?
Scene 1: Shopping mall atrium advertising
Recommended solution: P4 outdoor screen + intelligent brightness adjustment
Why? The traffic of people is large and the viewing distance is long, so you have to deal with the strong reflection on the glass roof. A shopping mall has installed a curved screen, and the customer flow has increased by 40%!
Scene 2: Stage background
Required functions: high refresh + quick disassembly
The most popular rental screen in the performance market is now 20% lighter than the old model, and the truck can add 30% more area, saving shipping costs is enough for half a year to eat lunch box.
Scene 3: Stadium fence
Core requirements: Anti-collision + wide perspective
You have to choose a box with a special reinforcement structure, and the athletes will not shake the screen when they hit it. The viewing angle should be at least 160°, otherwise the referee on the sideline will not be able to see the playback clearly.
Personal opinion time
Buying an LED screen is like finding a partner - there is no best, only the most suitable one. If you open a small supermarket, the entire P10 monochrome screen will be enough and save money ； If you hold a high-end press conference, you will have to spend a lot of money on a small distance. The key is to think clearly:
- Who should I show it to? (Determines clarity)
- How long does it take to open every day? (Determines energy consumption)
- How many years will you prepare to use? (Determine the budget)
Finally, I would like to say: Don’t believe in the "lowest price on the entire network". Only when you use a good screen for a long time can you really save money. I have seen too many buying miscellaneous screens with greed for cheap prices, but after changing two sets in three years, it is better to buy them directly!
