Boss Zhang, who just joined the industry, spent 180,000 yuan to buy an outdoor screen last year. As a result, it turned into a "crying screen" when the rainy season came. The maintenance cost was more expensive than buying a new screen! This is just like how a newbie can quickly gain fans. Choosing the wrong channel parameters will be useless. Today I will break it down and talk about the basics. After reading it, I will save you three years of detours.

▍​​Channel secret war: online price comparison VS factory direct purchase​​
Last year’s industry report showed that​ ​61% of purchasing disputes​ ​Due to incorrect channel selection. Here comes the point:
→ The price on the e-commerce platform is low, but the accessories may cut corners (such as using second-hand lamp beads)
→ The engineer's packaged plan saves worry but the intermediate price increase starts at 35%
→ The factory direct sales price is the best, but you need to confirm whether it includes a three-year warranty.

Here’s a little trivia: A truly reliable manufacturer dares to show you​ ​Workshop real-time monitoring​ ​, it’s like watching the production line live with goods. Last week, I helped the auto repair shop Lao Li inspect the factory and found that a certain company used a child's water gun to fool the waterproof test. It's strange that the screens produced by this kind of factory can withstand heavy rain!

▍​​Parameter Assassin: These numbers must be followed closely​​
Don't be fooled by sales about "imported chips".​ ​These three parameters are the lifeblood​​：

1. Brightness must be ≥4000nit (can be seen clearly even on cloudy days)
2. Refresh rate starts from 1920Hz (no flickering streaks when shooting video)
3. Protection level at least IP65 (proof against water spray and dustproof)

Last year, there was a joke in a shopping mall atrium screen - it was reflective like a mirror during the day, because it was a low-brightness screen for indoor use. Let me teach you a trick:​ ​Bring your mobile phone to the scene, open the camera APP and look at the screen​ ​, if scan lines appear, it means the refresh rate is not enough.

▍​​Acceptance of life and death situation: seven steps to avoid pitfalls​​
Don’t be in a hurry to sign for the goods when they arrive! Follow this process:
① Check whether the joints of the box are smooth (those with many burrs are less waterproof)
② Turn on the computer and check whether there are dark areas in the four corners (lamp bead consistency detection)
③ The water splash test lasts for 30 minutes (water beads will roll off a truly waterproof screen)
④ Play with a bright red background (inferior quality screens will turn white)
⑤ Check the thickness of the control card heat sink (thickness less than 2mm is easy to overheat)
⑥ Ask for a third-party testing report (focus on MTBF ≥ 50,000 hours)
⑦ Check the accessories list (less adapters can cost you two thousand more)

The most outrageous case I have ever seen: A certain real estate project did not check the heat dissipation during the acceptance inspection. As a result, the screen spontaneously "reduced fever" in summer, and the temperature was high enough to fry an egg. Now there is an unspoken rule in the industry——​ ​Those who dare to provide 72-hour aging video are the real manufacturers.​​。

▍​​Exclusive data stream​​
Project verification in 110 countries around the world shows that correctly purchased outdoor screens can​ ​Five-year maintenance costs can be reduced by 63%​ ​. There is an unpopular trick - ask the manufacturer to provide​ ​Close-up photo of lamp bead arrangement​ ​, the neatly arranged instructions use an automatic placement machine, which has a lifespan of more than three times longer than manual placement. Before your next purchase, remember to ask the salesperson to send you an aerial video of the factory area. Those who dare to show you even the raw material warehouse are the ones with the best skills!
