Have you ever encountered this situation? Lao Wang opened a hotpot restaurant in the mall and spent 200,000 yuan to install an LED screen as a signboard. As a result, the reflection was severe during the day and the light was brighter at night to cover his eyes. What's worse is that the screen position is too high, and customers have to look at the menu with their necks on their necks. After three months, the turnover fell by 15%. Today we will talk about where to put this LED screen so as not to waste money.

​​1. The golden triangle of outdoor advertising screen​​
Don’t think that just pushing the screen to the top of the building is done. There is a lot of knowledge here. Let me tell you something unusual:​ ​The screen 8-12 meters above the ground has an effective viewing distance of 3 times the height​ ​. For example, if you install it at a height of 10 meters, people 30 meters away can comfortably see the content. Last year, a milk tea shop on the pedestrian street suffered this loss. The screen was low and the crowds in line completely blocked the picture.

Here are a few hard indicators to remember:

• ​​The brightness must be ruthless​ ​: It is a self-entertainment at sunny day below 4,000 nits. The actual test data of a chain of fast foods has increased by 23% after meeting the brightness standard.
• ​​Have to play with the angle​ ​: The tilt of 5-8 degrees can remove 73% of the reflection, which is the same as applying the mobile phone anti-peeping film.
• ​​Maintenance channels must be reserved​ ​: The most outrageous installation I have ever seen. If you need to remove the air conditioner and external unit when repairing a screen

​​2. Invisible threshold of indoor stage screen​​
Friends who hold the New Year’s Eve may have a deep understanding - the stage LED screen looks cool, and the photos taken are all scan lines. The key here is​ ​Refresh rate starts at 1920Hz​ ​, below this number, the mobile phone video recording will definitely show ripple. The incident of the New Year’s Eve Gala last year was because a certain model marked "ultra-high brush" was used, but it actually only had 1440Hz screen.

Another easy pitfall is​ ​Grayscale​ ​. Friends who have held auto show know that the 18-bit and 16-bit grayscale screens have poor metal paint effects on luxury cars. The actual data show that high-end display scenarios can be presented with details that can increase grayscale by 37%.

​​3. The rules of survival in special scenarios​​
What do you fear the most about the fence screens in sports stadiums? It’s not sun and rain, it’s the audience throwing Coke! At this time​ ​IP65 protection level​ ​It came in handy. After a certain stadium installed such a screen, the number of repairs was cut by 80%. Let me talk about a cold knowledge: the floor tiles used for concerts may burn the dancer if the surface temperature exceeds 40℃.​ ​Honeycomb heat dissipation structure​ ​model.

The exhibition hall of the warehouse renovation should be paid more attention to, the space that is more than ten meters high.​ ​Arc correction technology​ ​It can adapt the screen to various strange angles. There is an interesting case in the art museum. They installed screens on the slopes and relied on algorithmic compensation to create a naked-eye 3D effect.

Recently, I discovered a strange phenomenon: many merchants would rather spend 100,000 more screens to buy, but would not be willing to spend 5,000 to make installation plans. If I ask, it’s like buying a sports car and adding 92-digit gasoline - no matter how good the hardware is, it will be ruined. Next time I see the salesperson boasting about "military quality". Remember to let him demonstrate the operation interface on the spot on rainy days. Real gold is not afraid of fire, and good screen is not afraid of hand slipping, right?
