Do you often see that kind of curved screen in the mall? Or have you seen a shiny step at the concert? These irregular-looking display devices are actually masterpieces of full-color LED special-shaped screens. Many newbies will have questions when they first come into contact with this kind of screen: Isn’t this thing just a bend of ordinary LEDs? Why is it several times more expensive? Today we will talk about what tricks do this "Transformers"-level display hidden?

1. A special-shaped screen is not a simple metamorphosis

Some people may think that a special-shaped screen is just a bend of an ordinary screen. In fact, this is like a clay-knit man-you can twist it with a piece of plasticine twice, can it be the same as the artwork carefully carved by the master? A true full-color LED special-shaped screen must pass at least three levels:

1. ​​Pixel arrangement should follow the shape​​Just like putting ceramic tiles on curved walls, you have to calculate the angle of each "tile"
2. ​​The power supply circuit must be redesigned​​, the circuit in the bent part must be bent and stretched like a spring
3. ​​The display content must be adapted to the shape​​Otherwise, if you broadcast a square advertisement on the round screen, all four corners will have blocked screens.

There is a particularly interesting case. A brand has built a spiral stair screen in Tokyo, and the display modules of each step must be programmed separately. The debugger said that he had been dreaming of calculating trigonometric functions for the past half month, but the naked-eye 3D effect presented in the end was indeed shocking.

Second and third major hardcore advantages support

​​Why are more and more places starting to use such "irregular" screens? ​ ​To put it bluntly, there are three "more" words:

• ​​More eye-catching​​: Data shows that the duration of the ads on the special screen is 47% higher than that of the ordinary screen.
• ​​More space-saving​​: For example, the transparent video wall with an 86% transparency is installed in the window without blocking the view and can broadcast advertisements
• ​​More resistant to trouble​​: IP65 protection level means that it can withstand the high-pressure water gun flushing, and it will be no problem for outdoor use for five or six years.

Last year, a shopping mall in South Korea installed a circular screen in an elevator shaft. It was just a test, but it turned out to be a check-in point for internet celebrities. The mall manager said that the elevator ride rate soared by three times, and sales in surrounding stores increased by 15%. This kind of "unexpected joy" cannot be given by ordinary square screens.

3. Guide to avoid pits when purchasing a newbie

The most troublesome thing for beginners is:​​How to judge the quality of a special-shaped screen? ​ ​Remember these five must-see parameters:

A customer had bought counterfeit goods before, but there was always a hidden belt around the corner of the screen. Later, I changed the products of regular manufacturers and used "low-bright high-gray technology" that I could not lose details in dark light environments. This technology sounds mysterious, but it is actually like the night mode in the mobile phone, but it can achieve a 1920Hz refresh rate and it won’t be distorted when watching the fast screen.

4. Installation and maintenance

Someone may ask:​​Will this kind of unusual screen be particularly delicate? ​ ​Let me put it this way, there is a factory in Shenzhen who has been used in tropical rainforest climate areas for three years, and even mold spots have not grown at the joints of the screen. There are three key points:

1. ​​Box material​​: Aerospace-grade aluminum-magnesium alloys are definitely more durable than iron frames
2. ​​Heat dissipation design​​: A good cooling system can extend the screen life by 30%
3. ​​Software System​​: The intelligent monitoring platform can alert potential faults 7 days in advance

I heard that there is a fenced screen in a gym that is hit tens of thousands of football times a year. The maintenance master said that they would do a "full physical examination" every six months, and they would use dynamic calibration technology to complete the entire screen inspection in five minutes. This kind of service support is the hidden bonus.

After so many years of display screens, I feel that the special-shaped screen is like the Lego building blocks in the display industry. It breaks the square mindset and allows display devices to truly integrate into the architectural space. Those manufacturers who can achieve 0.47mm slit accuracy can't be played without any technical precipitation. Next time you see a screen with a unique shape in the mall, you might as well get closer and look at the seams - there is real technical value hidden there.
