Ouch hey! Are you all crazy about the quotation? Curved screens, wavy screens, spiral screens... These special-shaped LED screens look cool, and they have more pitfalls when buying than shopping malls! Today we will lift the curtains of this industry and understand the purchasing methods hidden in corners!

1. The special-shaped screen is not a Transformer. Please clarify the needs before buying it.

Last year, a hot pot restaurant owner asked me for a big price to install a spiral screen, but the waiter always hit the edges of the screen. Here is an iron rule:​ ​The shape must be practical​​！

​​Let’s first understand the three soul-questions:​​

1. Is the installation location indoor or outdoor with wind and sun?
2. How many hours do you need to work continuously every day?
3. Are there any special load-bearing requirements? (For example, the hanging screen in the shopping mall atrium)

To give a real case: a music festival's main stage was equipped with a three-layer wavy screen, but it was short-circuited the next day when it rained. Later, it was discovered that the manufacturer cut corners and only achieved IP54 outdoor protection. So remember,​ ​The protection level of the special-shaped screen is one level higher than that of the conventional screen​​！

2. Text games in the parameter table

Don't be fooled by the "4K level display effect" technique! The most serious thing about the special-shaped screen is​ ​Pixel layout density​​and​​Splicing accuracy​​。

​​Four must-see hard indicators:​​

• Splicing seam ≤0.01mm (If you can get a bank card, you will be stuck, but you will fail)
• The viewing angle is ≥160 degrees (it is considered qualified if you don’t deform from the side of the station)
• The radius of curvature fit (the minimum bending angle should be found in the arc screen)
• Driver IC heat dissipation performance (contact the heating part of the prototype, direct pass for hot hands)

There was a shopping mall that suffered a lot: the parameters of the circular screen that were installed said "seamless splicing", and the light and dark stripes can actually be seen with the naked eye. Later, the test found that​ ​Uneven arrangement of lamp beads​​As a result, this kind of problem will not be written on the parameter table!

3. Special structures hide big pits

The most expensive part of the special-shaped screen is often not the screen itself. Let me reveal some common dark thunders:

1. ​​Steel structure brackets may cost more than screens​​
   The hanging spherical screen in an exhibition hall accounts for 60% of the total budget.

2. ​​Reserve enough space for maintenance passages​​
   There is a spiral stair screen in a bar, and the entire wall must be removed when changing the module.

3. ​​The heat dissipation design must be customized​​
   Like the streamlined screen commonly used in automobile 4S stores, the cooling hole must follow the shape.

Here is a tip: let the manufacturer provide it​​1:10 equal scale model​​, holding the model to mark the installation position can avoid 80% of the design pit!

4. Hidden test points for after-sales service

The repair of a special-shaped screen is ten times more troublesome than that of an ordinary screen! Focus on three points:

• ​​Modularity​​(Can you change it separately like a puzzle)
• ​​Spare parts inventory​​(Query whether there are more than 200 sets of commonly used module spare parts in stock)
• ​​Technicians' home visit time​​(Can you guarantee to arrive within 48 hours on heavy rainy days)

It’s smart to have a theme park: when signing the contract, it specifically stated that “pre-warehousing of spare parts for Typhoon season”. As a result, when encountering natural disasters, the maintenance efficiency is more than three times faster than the next park!

5. Big way to crack the price fog

Remember this formula: Reasonable budget = (displayed area × unit price) × 1.3 (special shape coefficient) + transportation insurance premium. Give a reference price list:

Notice! If the quotation is below 30% of this range, it is either cutting corners or second-hand renovation!

Editor's opinion: Buying a special-shaped screen is like inviting an ancestor home - the cooler the shape, the more difficult it is to serve! Those who dare to open a 100,000-square-meter production base, who can take out real videos of overseas arc screen projects, and are willing to sign the "three-year failure rate is less than 5%" agreement, are real gold and not afraid of fire. Remember, good screens can tell stories by themselves, and dare to spread out every solder joint for you. You won’t be wrong if you choose with your eyes closed!
