Recently when I was browsing short videos, I kept seeing shops in Dayao installing super-bright outdoor displays. To be honest, I was quite curious - how to choose this thing? Especially when I see that the screens in some stores are highly reflective during the day and dazzlingly bright at night, I am really afraid of spending money to buy a display. Is it the first time that a newbie comes into contact with an LED screen? Are you just as confused as I was at first?

Let’s talk about some outdoor LED screens first.​ ​fatal pit​ ​Bar: short-circuiting due to water intrusion during heavy rains, blurry screen visibility under the sun, and color patches appearing after half a year of use... These are not meant to scare people. I have personally seen a screen in a county supermarket that cost more than 200,000 yuan to install, but the result was a black screen during the rainy season. So today we will explain clearly how to find it in Dayao​ ​Both durable and clear​ ​outdoor display.

​​Key parameters must be paid close attention to these three items​ ​: The brightness should start at at least 4000 nits (don’t believe those who brag about 10,000-level brightness, too bright can hurt your eyes), the protection level must be IP65 certified (dustproof and waterproof is the basis), and the refresh rate must not be lower than 1920Hz (otherwise the video will be full of water ripples). Take the Sichuan restaurant on our street as an example. The screens they installed last year meet these standards. Now they play cooking videos on demand every day. The pictures are so clear that you can even see the pepper seeds. It is said that the number of customers has increased by 40%.

Speaking of the choice of installation location, here is a​ ​Lessons of blood and tears​ ​: Never install the screen under the shade of a tree! My cousin's milk tea shop suffered from this problem. The shadows caused by the swaying branches made the screen flicker. In the end, it had to be dismantled and reinstalled. The correct approach is to measure the building facade​ ​Sunlight angle​ ​, it is best to choose a southeast-facing wall to avoid direct sunlight from 2 to 4 p.m.

In terms of price, don’t just look at the quote per square meter. A friend who does wholesale told me that some merchants will​ ​Power module​ ​They are sold separately from the control system, and they tell you that you need to pay more after they are installed. Be sure to make sure these five items are clearly written in the contract: ① Does it include steel structure installation fee? ② Is the warranty period three or five years? ③ Is there a remote control system? ④ Automatic brightness adjustment function ⑤ Waterproof and lightning protection test report. By the way, customs has been strictly inspecting imported chips recently. Remember to ask the manufacturer to show​ ​CE and CCC dual certification​ ​, otherwise you may encounter the risk of having your chip deducted.

​​How to solve after-sales problems​ ​? Last week I specifically asked the industry masters. He said that most reliable manufacturers are now using "cloud monitoring" - for example, you can see the operating status of the screen on your mobile phone, and an automatic alarm will occur if the temperature is too high or the voltage is unstable. Here comes the point! Be sure to choose one that can provide​ ​24 hours video guidance​ ​Yes, especially in third- and fourth-tier cities like ours, the day lily is getting cold by the time engineers arrive. I heard that a Shenzhen company has set up a technical center in Japan to provide real-time support to Asian customers. The response speed is faster than that of local companies.

Finally, a little trivia: The treatment process on the screen surface directly affects the service life. Nowadays, high-end screens are used​ ​Nano coating technology​ ​, when rain hits the screen, water droplets will roll down, unlike ordinary screens that leave water stains. I asked about the price. This kind of treatment is about 300 yuan per square meter, but it can be used for three to five years longer, so it is worth it no matter how you calculate it.

If you are worried about finding reliable channels now, you might as well pay attention to those who provide​ ​Sports venue supply​ ​of manufacturers. The fence screens they make must withstand the test of fans smashing mineral water bottles, and the quality is absolutely excellent. Just like a new screen installed at a stadium in Tokyo last year, game replays were still being played in the storm. If a product of this level is placed at the door of a store, there is no need to worry about quality issues. After all, buying an outdoor LED screen is like looking for a partner. Just looking at the appearance is useless. The key is that it can withstand the sun and rain and maintain stable output for ten years.
