Xiao Wang, who has just joined the industry, has been too worried to sleep recently - a friend introduced a shopping mall LED screen project. Party A asked for a P2.5 pitch curved screen, but the price on the market ranged from 300,000 to 800,000. What's even more outrageous is that one supplier promised to "pay back the money in three months", but it turned out that there was a sky-high maintenance fee hidden in the contract. Today we will peel back the pants of this industry and talk about the three correct ways and five fatal traps in finding projects. (Last year, a supermarket chain believed in a "government-related customer". During the project acceptance, it was discovered that the screen color difference was serious. The balance was not returned and the dismantling fee was levied.)

1. Three formal channels for project information

​​Do you think industry exhibitions are just for displaying samples? ​ ​ That would be a mistake for Dafa. At a lighting exhibition in Guangzhou last year, there was a notice in the corner of a booth that said "Government Smart City Project Recruitment". This is the real money. A reliable channel looks like this:

• ​​Government procurement platform​ ​: Focus on the labels of "smart transportation" and "digital cultural tourism". The budget for such projects is sufficient and the acceptance standards are
• ​​Industry association bidding​ ​: For example, display industry association official websites often have sports stadium upgrade projects.
• ​​Overseas infrastructure list​ ​: A subway station indicator screen project in a Southeast Asian country was discovered through the website of the Ministry of Commerce.

But beware of phishing sites! Here’s a trick: A formal bidding document will definitely state “quality deposit ratio” and “acceptance standards.” Those that only state “strongest bidders will be given priority” are probably a bid trap.

2. Five life and death lines for evaluating projects

Anyone who has taken over a cultural plaza project in a certain county knows the pain - Party A insisted on installing an outdoor screen with a brightness of 8000cd/m², and as a result, it was so bright that surrounding residents complained collectively at night. These parameters must be adhered to:

1. ​​viewing distance​​：

   • Choose P2.5 or less within 3 meters
   • For 5-10 meters, choose P3-P4
   • P5 is enough for 10 meters away (can save 40% of the budget)

2. ​​Average daily usage time​​：

   • If it exceeds 16 hours/day, you must choose an industrial grade power supply.
   • Intermittent use can save money on cooling systems

3. ​​environmental adaptability​​：

   • The salt spray protection level of seaside projects must reach IP65
   • Places like hotpot restaurants must prevent steam and oil pollution

The most deceptive demand I have ever seen is that the Ice and Snow World needs to install an LED screen. As a result, the supplier did not conduct a low-temperature startup test, and the screen went black at minus 25 degrees Celsius. This special environment requires extra money for customization, so don’t save this money!

3. Seven cannibalistic clauses in the contract

Last year, a scenic spot project failed like this - the contract said "acceptance based on renderings", but Party A used movie screenshots as renderings. These items must be written into the contract:

• ​​Brightness uniformity ≥95%​ ​(Take a color calibration meter to measure on site)
• ​​Dead light rate ≤0.01%​ ​(No more than 3 bad pixels per square meter)
• ​​Color gamut coverage ≥110% NTSC​ ​(To prevent being fooled by low-end chips)

Pay special attention to "change disclaimer clauses". There is a lesson learned through blood and tears: Party A insisted on changing the curved structure halfway through the construction, but the manufacturer said that the modification fee would be charged separately. In the end, the gross profit of the project dropped from 30% to 2%.

4. Three artifacts that must be brought during acceptance inspection

Don't believe what Party A said: "Just look at it with the naked eye." A certain shopping mall project did not bring a light meter when it was accepted. As a result, the reflection was serious during the day but there was no way to protect the rights. Your tool kit must have:

1. ​​Color calibration instrument​ ​: Color check accuracy ΔE value ≤ 3
2. ​​Warming gun​ ​: The screen surface temperature cannot exceed the ambient temperature by 15℃
3. ​​signal generator​ ​: Continuously play video for 24 hours to detect heat dissipation performance

Here’s a trick: ask suppliers to provide a 72-hour aging test report. Regular manufacturers dare to show 2,000 hours of trouble-free operation data. This is true confidence.

The editor slapped the table and said

The next time you meet an agent who brags that "if you have connections, you can get a project," ask him three questions: "What's the tender number?" ""What is the warranty deposit ratio? ""What about acceptance criteria documents? "——Three axes went down, and Li Kui and Li Gui immediately appeared. Remember, a good project is like falling in love, there is definitely something wrong with rushing you to pay!
