When you walk in a shopping mall, you see deformable curved advertising screens, and you encounter interactive navigation walls in subway stations. Are you also curious about where these cool devices can be made? Last year, a milk tea shop owner spent 180,000 yuan to customize a display screen, but after installing it, he found that the screen looked grainy and looked like a mosaic. Today, I will help you avoid these pitfalls and talk about how to customize LED screens.

First figure out where you are being tricked.

Many novices tend to fall into these three places:
​​• Blind pursuit of "big and comprehensive""​ ​——A chain of gyms customized screens with motion sensing functions, but 90% of the functions became decorations.
​​• Ignore the usage environment​ ​——The screen of the seaside playground was not treated with anti-salt spray, and green spots appeared in half a year
​​• Parameter understanding bias​ ​——Interpreting the refresh rate of 1920Hz as resolution, the result is that the dynamic images are all smeared

Last year, the case of a certain brand's car 4S store was particularly typical: viewing angle compensation was not considered when customizing the curved screen. When the customer squatted down to look at the car chassis, the screen changed color, and in the end the screen had to be reworked.

These parameters are more important than price

When communicating with manufacturers, you must stick to these five key points:

A restaurant chain customized 200 kitchen displays last year, but failed to verify the operating temperature range. The high temperature in the kitchen caused the control box to crash frequently.

The customization process hides these tricks

From solution design to installation and debugging, these three links are most likely to cause problems:
​​① concept map scam​ ​——The renderings were shot using 3D renderings, and the "wave screen" in the atrium of a shopping mall transformed into a bathhouse tiles after landing.
​​② Replacing lamp beads secretly​ ​——After replacing the original lamp beads with second-hand refurbished ones, severe light degradation occurred within three months.
​​③ software castration​ ​——The control system locks some functions, and upgrades require additional fees.

The most amazing thing is the interactive floor tile screen customized by a certain scenic spot. The manufacturer covered the ordinary screen with tempered glass and called it "explosion-proof". As a result, the screen cracked after a child jumped twice.

Finding the right manufacturer can save you ten years of detours

To judge whether a manufacturer is reliable, look at these four points:
▶ Do you dare to let you visit the production line (pay attention to the brand and model of the SMT placement machine)
▶ Is there any real environment test video (don’t believe in studio sample photos)
▶ The response speed of the technical team (requires video connection to view the workshop)
▶ Details of after-sales service terms (whether travel expenses are included in door-to-door repairs)

There is a smart park project that is particularly clever: they require suppliers to engrave 12 key parameters on the screen frame, and directly use professional instruments to test them during acceptance. If they are not qualified, they will reject them on the spot.

The price and moisture are all hidden here

The quote for a customized screen of the same size may differ by 3 times, mainly in the following areas:
• Lamp bead brand (imported chips are 40% more expensive than domestic ones)
• Power module (military grade is 2 times more expensive than commercial grade)
• Structural material (aviation aluminum box is 60% more expensive than iron shell)
• Software licensing (the difference between lifetime free upgrades and annual charges is 5 times)

During a price comparison, a supermarket chain found that factory A's price was 25% lower than that of factory B. It turned out that the products used recycled heat sinks, and the screen was so hot in the summer that it could fry an egg.

Editor’s point of view: Customizing LED screens is just like custom-made suits. You can’t just look at the sample clothes and see if they are good enough, but also whether the tailor can tailor them to your needs. It is recommended to give priority to those manufacturers that dare to sign performance betting agreements and can provide full-process video tracking. Recently, I have discovered that some factories have begun to engage in AR remote acceptance. Customers can see through the internal structure of the screen while wearing glasses. This technology flow is trustworthy. Remember, good customization is the beginning of saving money, bad customization is the beginning of suffering!
