Alas, have you noticed it? Now I don’t have a large LED screen in the office lobby. I’m embarrassed to call it 5A Class A. But if you install the wrong position, you can change the decoration at the least, and if you are seriously, you can spend money every day to repair it. Last year, the property manager of a 5A office building complained to me that they paid 8,000 more for the monthly photoelectric bill of the 3-meter large screen they installed, and no one has seen it yet! Let's get to know today,Where should the LED large screen be placed to achieve results and save money?​。

1. These three major installation misunderstandings are pitting property

1. ​​Faced with the revolving door​: Direct sunlight causes the screen to turn white, the brightness must be adjusted to 8,000 nits at noon to see clearly, and the electricity bill will be doubled directly
2. ​​Hanged in the air-lifting area​​: Install a 10-meter-level high screen, and the elevation angle exceeds 30 degrees, the screen details cannot be seen. The cleaning lady needs to use a crane to wipe the screen
3. ​​Close against the green plant wall​: Water mist erodes the circuit board, so a certain project has changed the driver power supply three times in half a year

There is a real case: A building in Financial City installed a P2.5 screen on the back of the coffee bar, but 80% of visitors did not notice it at all. Later, it was changed to the elevator waiting area, and the customer stay time was extended from 30 seconds to 2 minutes, and the advertising conversion rate increased by 3 times.

2. Five hard indicators of the golden installation area

1. ​​The intersection of the mobile line​: The best distance from the main entrance is 8-12 meters, ensuring a 45° visual range for people entering and leaving
2. ​​Ambient illuminance ≤300lux​​: The secret to saving electricity! With the intelligent brightness adjustment system, the electricity bill will be reduced by 40%
3. ​​Installation surface load bearing ≥150kg/㎡​​: The 4K high-definition screen weighs more than 80 kilograms per square meter, and the walls need to be reinforced if they fail to meet the standards.
4. ​​Reservation of 1.2 meters of maintenance channel​: Don’t wait until the ceiling is removed when changing the lamp beads to regret it
5. ​Avoid reflective material background​: The marble wall needs to be matte, otherwise the picture will look like it is mosaic

Focus on brightness adjustment:​Indoor screen brightness recommended to adapt to the interval of 800-1200cd/m²​. The actual data of a certain entrepreneurial park: the morning peak was adjusted to 1,000 nits to attract attention, and the afternoon dropped to 600 nits to save electricity, and the comprehensive energy consumption was 37% savings than the fixed brightness.

3. Maintenance costs are hidden in the details

• ​​Don't face the air conditioner outlet​: Condensation water is generated alternately with hot and cold, and the life of the drive plate is shortened by 60%.
• ​​The splicing seams should be dust-proofed​: Dust accumulation can lead to color difference. The worst screen seams have accumulated thick gray and meaty
• ​​ Must have power-off memory function​: Sudden power outage and restart, the screen without this function needs to manually reset the playlist

Teach you a trick:​Choose a box with IP65 protection level​. Last year during the typhoon season, water was in the basement of a building in Qianhai. Only screens that met the protection standards survived in the same batch of equipment, saving more than 200,000 yuan in maintenance costs.

4. Content strategy determines success or failure

1. ​Time-sharing playback strategy​：
   • Morning rush hour: corporate promotional video + weather forecast
   • Lunch break: Discounts for surrounding merchants + live event broadcasts
   • Evening rush hour: traffic conditions + next-day meeting reminder
2. ​​Interactive function blessing​：
   • Scan the code to get the electronic guide map
   • Face recognition push floor guidance
3. ​​Image quality resolution selection​：
   • Select P1.8 within 3 meters of viewing distance
   • 5 meters away P2.5 is enough

A science and technology park has a new trick: visitors can edit blessings on their mobile phones by swiping the QR code, and it will be displayed on the large screen after 10 seconds. This function has soared the average number of people staying in the lobby by 200%, and has also become a hot local search.

5. Guide to avoid pits: Six questions to ask before signing a contract

1. "Can the control system connect to the building BA system?"
2. "How much does the failure rate of lamp beads exceed is considered as warranty?"
3. "Will there be an extra fee for software upgrades?"
4. "What solvent is used for daily cleaning?"
5. "How many signal source switching is supported at most?"
6. "How long will the plan be implemented after the power outage?"

The most pitiful contract trap I have ever seen: the procurement contract in a certain park said "free maintenance". Later, I found that only the lamp beads are not the power supply, so I changed the driver board to quote 8,000 yuan.

I have to say that LED large screens are not decorations at all, but the neural center of space operation. The newly built smart buildings are now linked to the waiting time of the elevator with large-screen advertising - people will push discounts for nearby merchants after more than 30 seconds. This kind of installation idea of ​​deeply embedded scenarios is the future trend. If you are planning to install a screen, remember to give the lobby floor plan to the professional team for thermal analysis first, and don’t wait until the installation is finished before slapping the thigh!
