Features and technical principles of the interactive LED floor tile screen

The led interactive floor tile screen is a novel digital ground display device specially customized for stages, catwalks, entertainment and other places. Its response is based on new digital technology, using microcomputer full digital processing, advanced circuit protection equipment, and video The synchronous control method achieves high-resolution soft color display effects and completes the perfect combination of stage virtual landscaping and performance interaction; it uses a high-strength tempered glass mask and a sturdy die-cast aluminum alloy support device. So what are the characteristics and technical principles of LED interactive floor tile screens?

The interactive LED screen adopts a video synchronization control scheme to achieve high-resolution soft color display effects, completing the perfect combination of stage virtual landscaping and performance interaction; it uses a high-strength tempered glass mask and a solid support device. The LED interactive floor tile display has a load-bearing capacity of more than 1 ton, strong impact resistance, and can be stepped on directly. The modular design can be quickly disassembled and assembled, and the protective structure with excellent performance can achieve seamless splicing and random combination.

Features of interactive LED floor tile screen

1. Fast and flexible installation: direct installation without tools or guide rail installation.

2. High load-bearing performance: Aluminum alloy material structure, high load-bearing capacity of up to 1.5 tons per square meter.

3. Excellent maintenance performance: can be directly replaced without dismantling adjacent boxes.

4. High contrast design: Technical design mask, clear playback effect.

5. Excellent low-brightness and high-gray effect, uniform grayscale display and good consistency.

LED interactive floor tile screen technology principle

1. The multimedia interactive system consists of an image motion capture device, a data transceiver, a data processor and an LED floor tile screen.

2. The image motion capture device captures and collects participants’ images and motion data.

3. The function of the data transceiver is to realize express transmission of data back and forth between motion captures.

4. The data processor is the core part that realizes real-time interaction between participants and various effects. It analyzes and processes the collected image and action data, and merges it with the data inherent in the processor.

The technology used in the LED interactive floor tile screen system is mixed virtual reality technology and motion capture technology, which is a further improvement of virtual reality technology. Virtual reality is a technology that uses computers to generate three-dimensional images to display and interact with a three-dimensional space. Through mixed reality, users can control virtual images while also being in contact with the real environment, thus enhancing the sensory visual experience.

DDW LED display manufacturers can carry out creative design and planning based on the actual needs of users’ LED interactive floor tile screen project content, integrate the software and hardware of interactive devices, project and customer needs, and can provide various interactive display types and methods to complete the project site System installation and debugging. And improve after-sales service, free training for users, free maintenance during the warranty period, and provide strong technical support.

Interactive floor LED screen application scenarios

interactive floor LED screen is suitable for science and technology museums, museums, planning halls, tourist attractions, hotel venues, commercial exhibitions, brand exhibition halls, children’s playgrounds, children’s palaces, theme parks, digital information, shopping malls leisure experience areas, education halls, entertainment venues, stairs Stairs and other manufacturers.

Front Access LED Display Solution

Front Access LED Display Solution

There 2 kinds for front access LED Display, one is use front access cabinets and the other is front access modules. But which one is better for my project? Here is our advert.
Here is our solution. If your project’s height is below 2.8 meters, then you should use front access cabinets to save cost. The modules is keep the same as back service. Cabinet only need more $30 for per square meter, but you save a lot from structure cost. Why maximum height is 2.8 meter? Because the maximum height of a front access cabinet is 3 meter. longer than that height will makes the cabinet too heavies to hold it’s structurer, some time will even have security prolem. ” But if my project height is longer than 2.8 meter can I use 2 front access cabinet?” the answer is no, the front access cabinet need a scroll space to open it for maintance, like the below picture.

front-access
front-access-case

For project which height is longer than 2.8 meter, and the structure must be front access, Use front access LED Display Modules is the best choice. Usually the modules is 4 times larger than back service modules, some the price is higher
