Guys, a guy who opened a gym asked me anxiously two days ago: "The LED screen I just installed suddenly turned black, and I couldn't even find the power button!" This incident made me suddenly realize that so many people didn't know the control path of LED screens. Today I will take you to find out the various things, so that you can be half an expert after reading them.

Where is the most scientific place to hide physical switches?

Have you noticed it? ​**Good LED screens are like agent equipment, and key buttons are hidden in unexpected places. There are three common locations: - ** The waterproof compartment on the side of the box (the one with a key, which is prevented from accidentally touching) - ** The bottom bracket slot in the bracket (you can touch the protrusions when you reach in) - ** The hidden grooves in the splicing seam** (you can open it with your fingernail)

Last time, when the customer installed an interactive floor tiled screen in the mall, the customer insisted on installing the switch on the front, but the naughty child pressed the phone three times on the day of opening. Now our professional engineering screens adopt double insurance design—​​Physical switch + software lock screen​, just like the steering wheel of a car, double protection is reliable.

How to use the remote control so that you don't catch it

Let me show you the group comparison data first:

Normal remote control	Professional engineering remote control
Valid within 10 meters	50 meters through the wall control
Single-band signal	Automatic switching between three bands
Easy to string code by pressing keys	Fingerprint encryption recognition

A customer who held a concert complained to me that the remote control I used before was completely unsuccessful under the stage lights. Now I have changed the equipment with anti-interference chips, which can be accurately controlled even in the laser lights in the disco. Key reminder:​Don't buy a remote control with learning function​​, it is easy to contact the screen signal of the next store, don’t ask me how I know...

Central control system to play advanced operations

Today's smart large screens are no longer as simple as turning on and off. Take the fence screen we made for the stadium as an example. The entire system can realize: - **Timed turn-off** (Accurately countdown of the event to seconds) - ** Group wake-up** (Open the main screen first and then start the auxiliary screen) - **Fault self-test** (Adhere to potential problems 48 hours in advance)

The most awesome is the oneGesture control module​, the transparent screen installed in the Science and Technology Museum last month, and the staff can cut the screen with a wave of their hand. But I want to remind newbies:​The central control system must be authorized​, don’t let the cleaning lady touch the core settings by mistake.

Is the mobile app control reliable?

This question needs to be broken down: ** Use temporarily, be careful when you use it for a long time. The advantages are indeed obvious - you can control the large screen in the mall by lying in the office, but there are many hidden dangers: - Network delays may lead to command accumulation - Public WiFi is easily hacked - System updates are prone to drop

Our solution isBluetooth + 4G dual channel control​, just like the main and backup system of a fighter. In the plan for chain supermarkets, the store manager uses a mobile APP and the headquarters uses a professional center console. The two systems do not interfere with each other and backup each other.

To be honest, choosing a control method is like choosing a mobile phone-​​Not the more functions, the better, the key is to be stable and easy​. I have seen too many customers greedy for fresh and fancy functions, but the basic operation has problems. Remember, a truly professional control system should make users unable to feel its existence, and this is the highest level. Next time someone brags about black technology to you. First ask him if he dares to sign a zero-failure agreement!
