Recently, I wanted to install a cool LED-shaped screen in the shopping mall atrium, but I was scared by the quotation - a round, wavy, or even irregular-shaped screen. Why is the price so much different? Don’t worry, today we will break it apart and talk about how to choose a display that breaks the rules so as not to be fooled.

Let's figure out what you want

Have you ever seen a beer bottle-shaped screen? This is what I did for Bar Street last year. There are three things you need to think clearly before buying a special-shaped screen:

1. ​​Surface arc​​: Do you want to do a 90-degree right angle or a 360-degree ring? The larger the arc, the higher the requirements for splicing technology
2. ​​Show content​​: Pure video playback or touch interaction? The latter must be equipped with infrared frames
3. ​​Installation environment​​: Indoor lobby or outdoor square? The price difference between waterproofing level and level 1 is 30%

A customer insisted on learning the cylindrical screen of the Apple store, but the ordinary curved screen could not achieve seamless splicing at all, and in the end he could only spend 200,000 more to customize the special box. So,​ ​Draw the drawings first and then inquire​​It can save a lot of money.

Finding the right manufacturer is half successful

Don’t believe the nonsense of “Special Offer for All Alien Screens” on Taobao! The manufacturers who are serious about the special-shaped screen have these hard indicators:
• ​​Module cutting accuracy​​±0.5mm, the splicing seam is thinner than the hair
• ​​Supports three-dimensional modeling​​, can turn your wild ideas into engineering drawings
• ​​24-hour technical support​​, you can find someone even if there is any problem with the screen in the middle of the night

Last year, I suffered a loss when I made a dolphin-shaped screen for the theme park. I found a second-hand dealer in the picture cheap, but when the animation was played, the scene always splashed. Later I found out that the module was inaccurately cut, which caused poor contact, and the return to the factory for repair delayed the entire opening season.

Don't be fooled by technical parameters

Remember these key numbers, sales will not dare to fool you immediately:

1. ​​Brightness adaptive​​: 800-1200 lumens indoors are just right, too bright and damage your eyes and also cost electricity
2. ​​Refresh rate ≥1920Hz​​, otherwise the short video will be full of ripple
3. ​​Viewing angle ≥160 degrees​​, ensure that the picture at the corner does not deform
4. ​​Radius of curvature ≤3cm​​, being able to do small arcs is the real ability

There is a wavy screen project in a shopping mall atrium. The supplier boasted about a 150-degree viewing angle, but the stores on both sides could not see the complete picture at all. Later, I changed the screen that supports 178-degree viewing angle, and the overall effect immediately improved by two levels.

Installation and maintenance hiding great questions

Quick-release box is not new, but​​Special buckle for special-shaped screen​​That's the key. A truly professional manufacturer will provide more than three types of connectors:
• Concealed buckle type for right angle splicing
• Universal joints for surface splicing
• Special angles must be customized fixtures

The most amazing case I saw last month - the sailing screen on the cruise ship deck is still as stable as Mount Tai when encountering wind and waves. The aviation-grade aluminum-magnesium-zinc alloy box used by people also has waterproof glue at the joints. This process cannot be done by a small workshop.

Speaking of prices, let me give you a brief introduction: ordinary square screens start from 3,000 per square square, and special-shaped screens basically double. But don't be scared by the high price.​ ​Five-year warranty + lifelong maintenance​​The service is worth this price. In the projects I have handled, customers who choose bargains have enough repair fees for three years to buy new screens, but they are willing to spend money on quality and have been using them for five or six years and are still the same as new ones.

Finally, I’ve inserted a cold knowledge: a truly high-end special-shaped screen can be played​​Naked eye 3D deformation​​. Just like at a brand launch conference last year, the screen changed its shape with the rhythm of the music, and this black technology relies on the intelligent control system behind it. So, buying a special-shaped screen is not just about buying hardware.​ ​Software system is the soul​​, this little money cannot be saved.
