Are you standing at the entrance of the mall, looking at the cool big screens, and your heart is filled with swaying: Where should I buy this thing? Don’t panic! Let’s talk about this question that drives novices crazy today. Two days ago, there was an old man who opened a milk tea shop. He bought a screen online with a cheap photo. But after installing it, he found that he couldn't see clearly during the day. Now his intestines are regretful - we can't step on this kind of pitfall!

1. Three major misunderstandings that must be understood before purchasing

​​Q: It is said that when buying a large screen, you need to look at the parameters. Which parameters are the most deceptive?​​

1. ​​Brightness Trap​: Don’t be moved just by looking at the numbers! The outdoor screen 4000cd/m² starts, but it must be confirmed that​Continuous brightnessNot peak brightness
2. ​​Waterproof Metaphysics​: IP65 protection sounds reliable, but in fact it depends on the material of the sealing strip - silicone can last for 5 years, rubber can last for at most 2 years.
3. ​Pixel trick​: The spacing parameters such as P6 and P8 must be calculated in combination with the viewing distance. It’s like you use P4 screens on a highway billboard, it’s just that you’re burning too much money

There is a cold knowledge: a truly reliable manufacturer will provide it​Intelligent brightness adjustment solution​​, the brightness will be automatically increased at noon, and it will save power to 70% on rainy days. This technology cannot be done by a small workshop!

2. Reliable channels are in the bottom

​Q: Is it more reliable to go offline to the market or online shopping?​​
Let's use actual cases to speak:

• ​Building Materials Market stalls​: The quote may be 30% cheaper, but 80% of it is a refurbished screen. Last year, a restaurant owner was caught and used it for half a year and the color difference was severe.
• ​​E-commerce platform flagship store​: Suitable for buying standard models, butCustomized requirements​And you also need to communicate offline. Pay attention to whether there are any physical factory videos in the store
• ​Direct purchase of industry exhibitions​: Exhibitions like Shenzhen Optical Expo can find real opportunities and compare seven or eight brands. Remember to provide the exhibitorCustoms Export Records​

Here is a knowledge point to focus on: manufacturers with a high export proportion, their products usually undergo strict environmental testing. I heard that 87% of the products of a company are sold to Japan and South Korea, and the climate is much wetter than in our south!

3. Price fog cracking technique

​​Q: Why can the price difference between the same size screen be two or three times?​​
Teach you four ways to see through the cost composition:

1. ​​Light bead cost​: The price difference between genuine lamp beads and counterfeit goods can reach 5 times. Use a magnifying glass to see if the lamp beads have brand logos.
2. ​Power supply solution​: Glue-filled waterproof power supply is 40% more expensive than ordinary power supply, but it will be worth it on heavy rains.
3. ​Structural Materials​: Aviation aluminum box is twice as expensive as iron box, but it can be used for ten years without rust
4. ​Control System​: The system with self-test function is 15% more expensive, but the later maintenance fee can be saved by half.

For example, it seems that the unit price is high when disassembling and assembling the box quickly, but the rental company can build this box three times faster with this kind of box, and the labor cost saved is enough to buy new equipment!

4. Guide to acceptance and avoiding pits

​​Q: How should the goods be accepted when they arrive on site so as not to suffer losses?​​
Remember this "five tests and three shots" principle:

• Test​Flatness​: Use a laser pointer to illuminate 3 meters away from the screen, and the spot is pulsating ≤2mm
• Test​Color difference​: Play pure white screen and observe whether there are any colored blocks with naked eyes
• Test​Protection​: Sprinkle mineral water on the surface, and the water droplets should have a lotus leaf effect
• Test​Interface​: HDMI and network port plug-in test one by one
• TestWarranty card​: Confirm the serial number is consistent with the fuselage
• PhotographedPackaging status​, shoot​Start screen​​, shootQuality Inspection Report​

The smartest customer I have ever met: I used a thermos gun to measure the temperature of the heat dissipation hole during acceptance, and asked to replace the power module on the spot after exceeding 55℃. Is this professional operation?

5. Maintenance and cold maintenance knowledge

Don't think it's over after buying it! There is a gym owner who has used the screen for three years and is the same as the new one. There are three secrets:

• Use monthlyNeutral cleaner​Scrub (don't use alcohol!)
• Reinforce all screws before the typhoon
• In winter, turn on at least 2 hours a day to prevent condensation
  There are also counterexamples: the large screen of a supermarket has long-term display of static logos, which leads to premature aging of local light beads. This kind of damage is not warranted!

If I ask me, buying an outdoor LED screen is like finding a marriage partner. You can’t just look at your appearance (display effect), but also look at your family background (manufacturer strength) and sense of responsibility (after-sales service). Those who dare to promise24-hour technical responseThe manufacturers usually have a complete operation and maintenance system. Finally, I would like to remind you, don’t save installation fees! I have seen too many cases where good screens are installed in a crooked manner and cause water intake. I really can’t save money from the professional installation team!
