I heard that the daily salary of a large LED screen can be 800 yuan now? Last month, my cousin took on the job of advertising screens in the mall as soon as he entered the industry and earned half a month of living expenses in three days. Are you also itchy and want to try it? Don’t worry, let’s talk about the tricks of this industry today!

​​How can novices get into the industry quickly? ​ ​
Alas, don’t say that there is really a shortage of people in this industry! Last week, I passed by Electronic City and saw five or six stalls posting notices of "urgently recruiting display screen installers." If you want to enter the industry, you must first understand three ways:

1. ​​Direct manufacturer recruitment​ ​: Many large companies will post "technical service positions" on their official website, but in fact they are installation positions
2. ​​Engineering business cooperation​ ​: Focus on companies that do commercial display solutions, they need temporary workers all year round
3. ​​Master brings apprentice​ ​: Go to the building materials market to squat, and when you see a fleet of vehicles equipped with screens, you will hand over a cigarette and talk.

Having said that, I know a young man born in the 2000s who specializes in installing transparent screens in high-end stores. Now his hourly salary has increased to 150. He has a trick - carrying a level and a laser ruler with him. These two tools alone make customers feel that their professionalism is soaring!

​​List of essential skills​​
​​Don't think it's just screwing! There are so many people who need to know this job​ ​：

• Understand the CAD drawings (at least distinguish between power cord and signal cord)
• Can use a multimeter to measure voltage (220V±10% is the safe range)
• Master basic programming (such as debugging the receiving card parameters)
• Understand the principle of heat dissipation (know the thermal conductivity of aluminum, magnesium, zinc cabinets)

There was a living case last month: A shopping mall always flashed after installing the P3 advertising screen, but it turned out that a novice had adjusted the refresh rate incorrectly. Nowadays, mainstream equipment requires ≥1920Hz, so pay special attention to this!

​​Guide to finding a job and avoiding pitfalls​​
​​The key point is here! Be sure to ask these five things before taking the job​ ​：

1. Payment method (daily settlement/stage settlement/full settlement)
2. Safety responsibility division (who buys insurance for high-altitude operations)
3. Technical support (whether is there any backend guidance when encountering difficulties)
4. Equipment belongs (don't touch screens of unknown origin)
5. Acceptance standards (Nine points of brightness need to be measured, but you can’t just look at it)

I remember that last year I helped students take a job with a stadium fence screen, but I didn’t ask for waterproofing standards and it was completely short-circuited after installing it and it rained. Now IP65 protection level is the basic requirement, so you must not be careless!

​​Revealing the salary market​​
The price difference in different scenarios can scare you:

• Store poster screen: 200-300/day (you need to know how to hide the power supply)
• Stage floor tiles screen: 400-600/day (must stay up late to debug)
• Sports event screen: 800+/day (you need to take the aerial homework certificate)
• High-end custom screen: negotiable (usually 3-5% of the total commission amount)

There is a cold knowledge: a master who can adjust color parameters can get an extra 30% of his salary. Now the industry benchmark requires ΔE≤1.5, and the color temperature must be accurately controlled at 6500K. These technologies have been learned and are absolutely popular!

​​Editor's opinion time​​
After working in the display industry for seven years, I found a strange phenomenon: the faster the technology iterates, the more part-time opportunities there are. Like the popular low-bright high-gray technology, many masters can't play with it, which gives young people a chance. It is recommended that novices first practice with the indoor screen. The brightness of 800-1200 nits is relatively easy to debug, and then challenge the 4000+ nits outdoor project after understanding it.

Finally, I would like to give you a message: What you are trying for in this industry is not about strength but about brain. Last week, I saw a girl writing an installation schedule program in Python, which directly tripled the efficiency of running activities. So, LED installation is not a physical job, it is a serious technical job!
