Alas, have you been confused by the installation location of the LED display recently? The shopping mall is hung in the air, on the fence on the side of the court, and at the entrance of the subway station-​Why do people put it there and it's almost awesome if we fiddle with it?​? Let’s understand this matter today!

1. Three iron rules for scene position selection

Last month, I passed by the Myeongdong business district in Seoul and saw the four-story transparent window screen in the mall. The light was shining during the day and the painting was bright at night. The boss chose this location so amazing! To put it bluntly,​A good position must meet three hard standards​：

1. ​​The traffic is large enough​: Locations with an average daily traffic volume of less than 5,000 people are basically useless
2. ​​No obstruction of vision​: The horizontal viewing angle should be >160°, and the vertical viewing angle should be >120°
3. ​​Strong environmental adaptation​: The temperature and humidity change should not exceed ±20%, and the light intensity should exceed 100,000 lux

A negative textbook: Last year, a shopping mall in Tokyo installed the P3 interior screen behind the glass curtain wall, but it turned out to be direct sunlight at noon.​The picture is as if it is mosaic​. Later, I moved to the shade and adjusted the brightness to 4500 nits, which immediately became clear!

2. Practical analysis of the five major golden points

1. Business Complex: You need more shame if you want money

• ​Atrium hoisting​: The best 8-12 meters above the ground, like the curved screen installed in a 17-meter empty space in a shopping mall in Singapore, with an average daily exposure of more than 200,000 people
• ​​Window Fusion​: Transparent screens with a transmissivity of >80% directly replace glass. After a brand store in Seoul did this, the store entry rate soared by 35%.
• ​​Elevator Interaction​: Floor tile screen with touch function, the average residence time is extended by 2 minutes

2. Cultural and sports venues: Safety first

• ​Fence protective screen​: I have to use IP65-level waterproof box, a Tokyo court screen withstands a level 12 typhoon
• ​Scoreboard​: The vertical installation angle should be <15°, and it will be difficult to watch the audience.
• ​Stage background​: The pixel pitch is ≤P2.5, and the refresh rate is ≥3840Hz to withstand 4K live broadcast

3. Transportation Hub: Practicality is King

• ​​Above the gate​​: Height 2.2-2.5 meters, the highest information acquisition efficiency
• Column surround screen: columns with a diameter of >1.2 meters can only be installed. After the Seoul Metro Station is renovated, advertising revenue has increased by 40%.
• At the end of the channel: Install P4 screen at a position with a viewing distance of > 10 meters, with the best content recognition

3. Don't step on these pitfalls

1. ​Direct sunlight​: Outdoor screen dressing noodles? Wait for changing the lamp beads every three years!
2. ​Ventilation blind spots​: The screen in a Southeast Asian shopping mall is installed in the air conditioner return air outlet, and three cooling fans burned in half a year
3. ​​Electromagnetic interference zone​: <5 meters away from the substation box? Wait for the snowflakes to float in the picture!
4. ​​Vibration high frequency zone​: Install ordinary screen next to the subway track? There will be a death light in three months!

​​Tell you a site selection guide​：
The shady and ventilated people gather together, and the visual angle should be matched
Electromagnetic vibrations are far away, and it will take only three years of repair to achieve the goal.

4. How to break special scenarios?

Q: How to install curved walls?

A: You have to use a flexible module, like the P4 curved screen installed in a shopping mall in Singapore, with a bending radius of 0.8 meters, and the fit is similar to wallpaper. The key is to do 3D modeling in advance, with the error of <2 mm!

Q: How to choose an open-air square?

A: Remember three numbers:

• Screen height = maximum visual distance ÷ 10 (for example, if the visual distance is 50 meters, the 5-meter high screen is installed)
• Brightness = ambient light × 3 (50,000 lux is matched with 15,000 nits on sunny days)
• Inclination angle = arctan (screen height/visual distance), ensure that the screen does not deform

5. Editor's opinion: It will be more exciting to play like this in the future

I have to say that the location selection will change in the next three years:

1. ​​Space folding screen​: "waste locations" such as columns and corners can be converted into advertising positions
2. ​​Environmental adaptation​: Automatically adjust the content duration according to the traffic
3. ​Multi-screen linkage​: 20 screens in the mall can be made into a super canvas

Just like the intelligent guide system made in a business district in Tokyo now, the screen pushes coupons 200 meters away from the store, and the screen within 50 meters directly guides the way - this is what it is calledUse the position to make flowers​! So, choosing the right position is not only a technical job, but also a business practice!
