In the past two years, there have been more and more large LED screens on the streets, and even the convenience store at the entrance of the village has installed moving advertising screens. But do you know? Some people burn a BMW for the same size every year for screens, but some people can make money by saving electricity - how powerful is this thing? Let's break it up and say it.

1. Brightness IQ tax saves the Tesla

The most outrageous case I have ever seen: a shopping mall uses an outdoor screen of 8,000cd/m2. It is as bright as an electric welding at noon, and the monthly photoelectric bill is more than 20,000 yuan. In fact, the smart screen can automatically adjust the brightness, and it will automatically drop to 300cd at 2 a.m. It will save 30% of the electricity bill once the power saving mode is turned on.

​​The key is these three indicators:​​

1. ​​Low bright high gray technology​​: Maintain color levels in dark environments, this is the principle of the midnight mode used by KTV
2. ​​Refresh rate ≥1920Hz​​: The screen shot of mobile phones does not flash with stripes, and live streaming does not overturn the car
3. ​​Pixel spacing adaptive​​: There is no difference between P6 and P10 from 5 meters away, but the latter is 40% cheaper

(Last year, a hot pot chain replaced a screen with a light sensor, saving 42,000 yuan in electricity bills per store, and 300 stores across the country directly saved the net profit of a listed company)

2. Waterproof and anti-death technology

You must have seen screens that were smashed by naughty kids, but the protection level of the new screen can make you fall off:

• Floor tiles and screens bearing 2 tons/㎡, high heels will not crack
• Outdoor screen can withstand level 10 wind power on typhoon days
• The transparent screen is still as transparent as before after the rainstorm

There is a real case: the fenced screen of a coastal city stadium has withstood 17 typhoons in three years, and the maintenance fee is 65% lower than that of traditional neon lights. The secret is the IP65 protective box, which is sealed with six layers inside and outside, and you don’t even have to worry about salt spray corrosion.

3. Invisible money printing machine for installation and maintenance

Traditional billboards need to crawl into scaffolding if they change the screen, and now the smart screen can change the content remotely. What's even more amazing is:

• Quickly disassemble and assemble the structure to speed up the construction of rental screens by 3 times
• The front maintenance design can be replaced without removing the walls.
• The fault module automatically alarms, and the repairman takes GPS positioning to the problem point.

Last month, a music festival used a screen with an IoT card. The backend could see clearly which box heated up and which cable had poor contact. Compared with manual inspections five years ago, maintenance costs have been reduced by 78%.

Soul-questioning session

Q: It is said that the lifespan is long. How many years can it be used?
A: Scenarios! The screen used in barbecue restaurants generally lasts for three years (oil fume corrosion), but the screen of the conference room with a liquid cooling system can last for ten years. Focus on the power supply solution - it is not a dream to live for 5 years more than ordinary people.

Q: Can you buy a second-hand screen?
Teach you three ways to check the machine:

1. Play 256-level grayscale image to see color transition
2. Work continuously for 8 hours to touch the heat sink temperature
3. Disassemble the control card to see the year of the chip (those produced after 2020 will only support HDR)

The storm of the old industry

I tell you that LED screens are no longer the era of "just as long as they can be bright". Last year, a transparent interactive screen was created by a car company's flagship store. When a customer pointed to a car through the glass, the parameter video would automatically pop up on the screen. As a result, the average customer price increased by 37%, and even friendly competitors came to take photos.

What's even more amazing is the new floor tiled screen, which will leave footprints of light and shadow when you step on it. A scenic spot has installed a screen like 200㎡, and the tickets have increased by 30 yuan and are full every day. If I ask, this is not a display screen, it is a money printing machine!

Finally, I will get a hard-core data: the 2024 industry report shows that the smart dimming system saves 38% of the screen annually, and the failure rate drops from 19% to 2.3%. Next time, remember this mantra when selecting the screen: "The higher the brightness, the better, intelligence is the real money ability! "
