1. Where is the switch hidden? Different scenarios have their own ways

Hey, everyone who makes LED advertising screens knows that the switch position is not just as simple as the power button. Take three common scenarios:

​​1. Outdoor large screen​​
Usually hidden in three places:

• Access hole on the back of the screen (waterproof box + mechanical lock)
• Power distribution room control cabinet (with leakage protection switch)
• Cloud management system (remote control via mobile APP)

​​Give a chestnut​ ​: For a 32-meter-wide curved screen in a shopping mall, the switch system is divided into three levels - local physical switch + power distribution room master control + smart middle-end cloud management, with triple insurance to prevent accidental touch.

2. How to choose the switching system? Look at these four diamond parameters

​​Focus on​ ​: Nowadays, high-end screens use smart switch systems. Like the solution we made for Tokyo Stadium, the switch can automatically adjust the brightness according to the ambient light, saving 40% of power than traditional switches.

3. Three taboos on switch position

1. ​​Don’t install it on the front of the screen​ ​(The naughty kid gets into chaos when he presses the button)
2. ​​Stay away from high temperature and high humidity areas​ ​(Absolutely not next to the kitchen exhaust outlet)
3. ​​Avoid strong electromagnetic interference​ ​(5 meters away from the transformer)

​​Lessons of blood and tears​ ​: A certain hot pot restaurant installed switches on the exhaust vents and changed three sets of control systems in half a year. Finally, the problem was solved at the cashier.

4. Tips for daily maintenance

• ​​Must do every week​ ​: Check whether the switch interface is oxidized (wipe with alcohol cotton pads)
• ​​Required every month​ ​: Test the emergency power-off function (the screen should go out within 3 seconds after the switch is turned on)
• ​​Must check every quarter​ ​: Upgrade control software (prevent system vulnerabilities)

​​Technology flow reminder​ ​: With intelligent adjustment switch system, remember to turn off the "brightness memory" function in automatic update, otherwise the screen will be too bright on rainy days.

personal opinion time

Turning on and off an LED advertising screen is like putting a film on a mobile phone - it looks simple, but in fact it's all about the details. Don’t be greedy for cheap and use off-brand controllers. We have seen too many cases where the entire screen was burned out due to switch failure. Nowadays, high-end solutions adopt modular design. Power management, brightness adjustment, and fault diagnosis are integrated into a palm-sized box. This is really worry-free. Before installing a screen next time, remember to ask whether the switch system has these three certifications:

1. Overvoltage protection test report
2. 100,000 compression life certificate
3. Electromagnetic compatibility test certificate

After all, although the switch is small, it controls the lifeblood of the entire screen!
