As a new type of stage display device, LED floor tile screen adopts video synchronization control method to achieve high-resolution soft color display effect, completes the perfect combination of stage virtual landscaping and performance interaction; it uses high-strength tempered glass Face shield, strong support device of die-cast aluminum alloy.
It can be widely used in LED floor tile screens, mainly used in stages, concerts, performances, bars, discos, shopping malls and other fields. The LED floor tile screen has an exquisite and high-grade appearance and scientific design. It uses high-quality aluminum alloy, advanced electronic ceramics and other materials for heat conduction and heat dissipation. It takes brand-new digital technology as the core, adopts microcomputer full digital processing, and advanced circuit protection equipment. Know the LED floor tile screen After having the above application scope, let's take a look at the characteristics of LED floor tile screen:
The load-bearing capacity is more than 1 ton, the impact resistance is strong, and it can be directly stepped on; the modular design of quick disassembly and assembly, and the excellent protective structure can realize seamless connection and random combination. This product is suitable for various forms of performance stage, such as: disco stage, T-stand, concert stage and theater stage, etc.
Powerful PC mask: The surface of the box does not need to be tempered glass, and the light transmission is good. The point-to-face support design of the module can be directly stepped on;
Waterproof, explosion-proof and low temperature resistance: a single module is independently waterproof and can be applied to all outdoor cold climates;
Interaction effect: multi-touch function, no need for external interactive device, realize human-computer interaction;
Quick maintenance: simple disassembly and assembly, easy maintenance;
Flexible shape design: it can be spliced at will, and a variety of forms can be used flexibly;
Fast and flexible installation method: It can be installed directly without tools or guide rails;
High load-bearing performance: aluminum alloy material structure, high load-bearing capacity can reach 1.5t per square meter;
Excellent maintenance performance: It can be replaced directly without removing the adjacent packing box;
High-contrast design: technically designed mask, clear playback effect;
Excellent low brightness and high grayscale effects, uniform gray display and good consistency.
The technical principle of LED floor tile screen:
The function of the data transceiver is to realize the express transmission of data back and forth between motion captures;
The multimedia interactive system is composed of an image motion capture device, a data transceiver, a data processor and an LED floor tile screen;
The image motion capture device realizes the capture and collection of participant images and motion data;
The data processor is the core part that realizes the real-time interaction between participants and various effects. It analyzes and processes the collected images and motion data, and realizes the combined processing with the inherent data in the processor.
Standards for distinguishing the quality of LED floor tiles:
White balance effect:
The white balance effect is one of the most important indicators of the LED floor tile screen. In color science, when the ratio of the three primary colors of red, green and blue is 1:4.6:0.16, pure white will be displayed. If the actual ratio is a little different, there will be a deviation of white balance. Generally, pay attention to whether the white is blue or yellow. Green phenomenon. In monochrome, the smaller the brightness difference and wavelength difference between individual LED floor tile screens, the better. Standing on the side of the screen, there is no color difference or color cast, and the consistency is better. The quality of the white balance is mainly determined by the LED die brightness wavelength ratio and the control system of the display screen. The die also has an impact on the color reproduction.
The color reproducibility refers to the color reducibility of the LED floor tile screen. The color displayed on the display screen must be highly consistent with the color of the playback source, so as to ensure the realism of the image.
Whether there is mosaic or dead spots:
Mosaic refers to the small four squares that are always bright or black that appear on the LED floor tile screen. It is a phenomenon of module necrosis. The main reason is that the quality of the IC or connector used in the display is not good enough. Dead point refers to a single point that is always bright or black that appears on the display. The number of dead points is mainly determined by the quality of the die and whether the manufacturer's anti-static measures are perfect.
Whether there are color blocks:
Color block refers to the obvious color difference between adjacent modules of the LED floor tile screen. The color transition is based on the module. The color block phenomenon is mainly caused by the poor control system, low gray level, and low scanning frequency. Caused.
Stability refers to the reliable quality of the LED floor tile screen in the aging stage after it is made into a finished product. It can be judged by the aging record of the manufacturer to get the status of the screen during aging.
