Technical threshold behind customization requirements

Recently I encountered a funny and hilarious case: a shopping mall insisted on customizing wavy LED curtain walls, but it took three suppliers in three months to complete the process. This reminds me of​ ​Customized special shapes​ ​It's far from changing the shell. A truly professional service provider must have three major abilities:

• ​​Structural Engineering​ ​: The curved screen radian error must be controlled within ±0.5°
• ​​Heat dissipation and reconstruction​ ​: The duct system must be redesigned in a special shape structure
• ​​Signal compensation​ ​: Non-standard arrangement requires special correction algorithms

Last year, I came into contact with a circular screen project of a landmark building in Singapore.​ ​16 sets of different curvature modules​ ​The precise splicing and aerospace-level positioning instruments were even used during debugging. Manufacturers who do not have some technical reserves can't take this level of customization.

Core parameter comparison list

What are the most feared of custom screens? It’s not that the price is high, it’s that it’s spending a lot of money to buy scrap iron! Remember this comparison table:

Have a cold knowledge:​ ​1920Hz refresh rate​ ​It is not only a guarantee of smooth picture, but also a touchstone for circuit design level. When a ski resort customized floor tiles, the supplier could not come up with a high-frequency driving solution, which eventually led to a smooth accident during high-speed photography.

Customized full process pit avoidance guide

1. ​​Demand confirmation phase​ ​: Requesting supplier to issue​ ​Optical simulation report​​
2. ​​Program design stage​ ​: Focus on review​ ​Thermal simulation data​​
3. ​​Installation and debugging phase​ ​: Must include​ ​72-hour stress test​​

Let me tell you about the inside story of the industry: manufacturers who dare to accept custom orders,​ ​Monthly production capacity is at least 5,000 square meters​ ​Get started. The small workshop cannot even do standard products well, let alone deal with emergencies in customized projects. Last year, a music festival customized the car screen, and the supplier temporarily sent a 10-person technical team with him.​ ​Full spectrum analyzer​ ​The color adjustment on site is to preserve the performance effect.

Disassembly of high-frequency problems

Q: Will customization of special sizes affect lifespan?
A: The key is​ ​Box structure design​ ​, a customized screen with aerospace aluminum-magnesium alloy frame, has an actual service life of 23% exceeding the standard product.

Q: How to verify the true capabilities of suppliers?
A: Request a visit​ ​Automated patch workshop​ ​, observe whether the equipment is equipped with an offline programming system. A real customization expert must have​ ​Multiple parallel production lines​​。

Q: How to ensure after-sales service for multinational projects?
A: Focus on investigation​ ​Localized service outlets​ ​, high-quality service providers have spare parts warehouses in major countries. A Middle East project broke out suddenly and the supplier replaced the faulty module from the Dubai warehouse within 24 hours.

The most shocking customization case I have ever seen is the 360° circular fence screen of a gymnasium in Tokyo. It took 18 months from the design to the implementation of the plan.​ ​Seismic test​ ​Just did three rounds. Now I finally understand that the real customization service is not "processed according to the diagram", but​ ​From technical pre-research to scenario implementation, the whole chain of hard work​​。

It is recommended to focus on three points when choosing a service provider: Is there any?​ ​Independently developed calibration system​ ​, dare to make it public​ ​Aging test data​ ​, can it be provided​ ​Operation and maintenance cases over five years​ ​. Next time you negotiate, you might as well ask directly: "What is the most complicated custom project you have ever done? " This question can instantly test the other party's true level.
