Last month, a shopping mall in Shanghai opened. Lao Zhang from the purchasing department found a small workshop with cheap price. As a result, the color block fault occurred after three days of installation of the LED large screen - the rework fee alone cost 230,000 yuan more! Buying LED screens these days is like opening a blind box. Today, let’s talk about it​ ​How to spend money on the blade​​。

1. Three major channels of life and death: What is more deadly than price is hidden costs

Recently, I helped my friend pick a stage screen and touched the market:

Take a chestnut: A wedding company bought P3 rental screen at the wholesale market with cheap prices, and a large area of ​​mosaic appeared at the event. Later, it was found that​ ​Refresh rate is only 960Hz​ ​, no high-definition picture can be taken at all.

2. Four combos to avoid pits: A must-see lesson for beginners

​​• Parameters must be tested on site for autopsy​​
Take these four-piece sets to inspect the goods:

1. Optical detector (measure brightness uniformity)
2. 4K test film (see color transition)
3. Slow-motion shooting on mobile phone (check refresh rate)
4. Temperature measuring gun (heat dissipation after working for 1 hour)

​​• The black hole in the contract​​
The most difficult terms ever seen:

• Software upgrades charge 5,000 yuan per time
• Door fees charged for more than 3 maintenance
• The warranty period is calculated from the installation date rather than the acceptance date
  ​​Recommended to be slap: including three years of system upgrade service​​

3. Innovative procurement method: Smart people play like this

​​• Save shipping costs for order purchase​​
Last year, five shopping malls in Shenzhen jointly purchased, reducing logistics costs from 18% to 7%. The key is:

1. Unified technical parameters
2. Agreed to ship in batches
3. Shared installation team

​​• New ideas for renting instead of buying​​
A certain music festival uses a rental model, saving 610,000 yuan in purchase expenses for 300㎡ stage screen. Remember these three points:

1. Choose a quick-release box (6 people complete in 2 hours)
2. Confirm that there is accidental insurance (lightning strike, water inlet is fully compensated)
3. Requires technicians on site (hourly salary not exceeding 200 yuan)

​​• Government wool pulls hard​​
This year's digital economy subsidy policy:

• Subsidies for digital transformation of commercial entities: 15%-25%
• Interest subsidy loan for equipment procurement of cultural and tourism projects
• High-tech enterprise procurement tax credit

​​Exclusive information​​：
Industry data shows that LED screens are purchased​ ​After-sales cost accounts for 19% of the total budget​ ​. Focus on whether the supplier has:

1. 24-hour response center (the plan is released within 2 hours)
2. Spare parts warehouse within 5 kilometers
3. Original engineer team
