When you look at the cool LED advertising screens all over the streets, do you always wonder - how do you do these moving light and shadow magic? If you sign up for a training class, you're afraid of being cut off, and you can't find a way to learn on your own. Why is it so difficult to learn a craft these days? Don't worry, today we will dig into the knowledge of this industry.

Last year, my cousin spent 6800 to sign up for a crash course, but after three months of studying, he couldn't even distinguish the model of the driver board. Later, I started working with the installation team and found out the ropes. ​ ​When it comes to learning about LED advertising screens, just listening to a lecture is really not as good as tightening the screws with your own hands.​​。

​​Let me tell you a few lessons of blood and tears first.​​：

1. Most of the online courses that offer "teaching and meeting" are teaching outdated P10 monochrome screen technology.
2. The gold content of the certificate is more valuable than the packaging of instant noodles (the most outrageous institution I have ever seen dares to issue an "International LED Master Certificate")
3. The real skill lies in the construction details (such as how to route wiring to save 30% of power cords)

I have a friend who owns a gym. After watching videos and learning for half a month, he dared to take over the installation of store signs. As a result, the positive and negative poles of the control card were connected reversely, which burned the entire screen and tripped it for three days. So​ ​Don’t act recklessly without a master to guide you. The tuition fees paid in this industry are real money.​​。

Now let’s talk serious——​ ​Where are the reliable learning channels?​​：

• Equipment manufacturer training department (many large manufacturers have free novice camps)
• Install the company's apprenticeship system (low monthly salary but able to touch real machines)
• Industry exhibition training area (for example, during the Guangzhou Exhibition, there will be real machine disassembly)
• Vocational technical schools purchased by the government (the curriculum is down-to-earth and the tuition is subsidized)

The most deceptive case I have ever encountered was from a training institution, where the teaching content was still based on the asynchronous control system from five years ago. Nowadays, the streets are full of synchronous control systems, and students become unemployed after graduation. so​ ​When choosing a course, you must first look at the equipment list. Only those with high-definition video processors and receiving cards are worth studying.​​。

The easiest trap for novices to fall into is "software worship". Some students insist on spending time on software such as PS and AE, but as a result they cannot even do the most basic signal debugging. Focus here——​ ​Master the seven core skills first​​：

1. Screen structure awareness (box, module, mask)
2. Power supply power calculation
3. Signal transmission principle
4. Interpretation of fault codes
5. Basic debugging tool usage
6. Safe and standardized operations
7. Simple content adaptation

You may want to ask: Is it possible to study by yourself? Based on my experience in leading newcomers in the past five years, I compiled a competency comparison table:

Recently I discovered a new trend - VR simulation installation training. Some students practiced disassembling and assembling glasses for three days and were able to use the real machine more efficiently than the master. However, this set of equipment costs more than 200,000 yuan, and ordinary training institutions cannot afford it. so​ ​Choosing an institution depends on the investment in practical training equipment. Those who even search for real machines will be blocked as soon as possible.​​。

There is another unpopular knowledge point: many city human resources and social security bureaus have special subsidies. Last year, I took a laid-off worker and took the intermediate electronic equipment assembly certificate. The government reimbursed 2,000 training fees. So​ ​Check local policies before studying, don’t be foolish and pay the full amount yourself.​​。

Editor's point of view: Learning LED advertising screens is like learning to swim - no matter how long you paddle on the shore, it is better to splash twice in the water. If you really want to get into the industry, remember three things:——​ ​Find an agency with real machines, work with masters who have done real work, and take orders from people who can practice.​ ​. The day you can handle the lightning protection and grounding of outdoor screens on your own, your job will be secure.
