Have you ever seen any advertising screens in the mall that follow people? Or have you seen a ground display screen that can use your feet to make fireworks? These black technologies that make people shine are actually LED interactive displays. A novice novice may ask: Where should I find this kind of "talking" screen? Today, let’s take a look at the tricks in this industry.

​​Ask a real question first​​: Why do some of the same LED screens can only display advertisements, while others can interact with people? The key lies in three core technologies:

• ​​Induction layer technology​​: Infrared sensing, radar wave, pressure sensing... Different scenarios should be equipped with different "tactile nerves"
• ​​Data processing speed​​: From the time you lift your foot to the screen reaction must be completed within 0.03 seconds
• ​​Show synchronization rate​​: There must be no smear or stuttering on the dynamic screen

To give a real example, the interactive floor tiles screen of a theme park will cause water ripples when tourists step on it. This kind of screen not only needs to withstand tens of thousands of tramplings a day, but also needs to work as usual on rainy days. I heard that the manufacturer has made IP68 waterproof screens, and even the screws are coated with three layers of anti-rust coating.

​​Three major application scenarios for interactive screens​​：

1. ​​Commercial space​​

   • The fitting mirrors in the clothing store can be automatically recommended for matching
   • The floor screen in the dining area will bloom with flowers as you step by step
   • You can turn pages to see product details by using gestures on the window screen

2. ​​Entertainment venue​​

   • The ground screen on the concert stage can sense the dancer's movements to trigger the lighting effects
   • The museum's cultural relics display screen can be viewed with a 360° wave

3. ​​Public facilities​​

   • The navigation screen of the subway station uses gestures to check the route
   • The registration screen in the hospital hall supports voice interaction

​​Now answer the core question​​: Where can I find a reliable interactive screen supplier? It mainly depends on these three channels:

1. ​​Professional manufacturer​​
   This type of enterprise usually has independent research and development capabilities. For example, a Shenzhen enterprise has made a complete fence interactive system for Tokyo Stadium. Their screen can display athlete data in real time and can automatically switch screens according to the progress of the competition. The key depends on whether the other party has:

   • Environmental simulation laboratory (can measure extreme environments of -40℃ to +80℃)
   • Stress test report (such as floor tiles and screen bearing 2 tons/㎡)
   • Case video library (actual projects are more convincing than parameters)

2. ​​System Integrator​​
   Some projects need to package the interactive screen, audio, lighting, and central control systems. At this time, we need to find a service provider that can provide a complete set of solutions, and focus on:

   • Is there any interactive software developed independently?
   • Can you do multi-device linkage debugging?
   • Whether to provide more than three years of system maintenance

3. ​​Rental service provider​​
   It is more cost-effective to rent a temporary event than to buy it. For example, the stage screen commonly used in music festivals can be achieved by professional renters:

   • Completed 200 square meters of screen construction in 4 hours
   • Equipped with rainproof and dustproof transport box
   • Staff on site with technicians

​​Purchase and avoid pits​​(must read for beginners):

1. Don't be fooled by "sensitive" publicity, and test the response speed at different angles on-site
2. Ask for waterproof and dustproof level (at least IP65 outdoor)
3. Check out the brand and packaging process of lamp beads (related to service life)
4. Requires 12-hour continuous running test video
5. Confirm whether the software system supports secondary development

Some people may ask: Why do some interactive screens become slow to react after half a year of use? Mostly there is a problem with the heat dissipation design. A good product will be equipped with a micro fan in the box. Even if it works continuously for 24 hours, the internal temperature will not exceed 55℃. For example, for window screens with touch function, the surface must be coated with anti-fingerprint coating, which many merchants will not tell you on their own initiative.

Editor's opinion: Instead of comparing prices everywhere, it is better to go directly to the manufacturer to look at the production line. A truly powerful company is fully automated from SMT patches to finished product testing. Next time I encounter sales that boast about "imported chips", I might as well ask: Can your equipment be photographed on the chest to ensure that the screen will not be black for three years?
