Depda control system provides the perfect solution for LED six-sided spherical screens

The Depda control system is like a precise key, specially tailored to create a perfect solution for the LED six-sided spherical screen, successfully overcoming many problems that have plagued the industry for a long time. In the past, watermelon skin LED spherical screens were limited by their own pixel arrangement characteristics, and there was an embarrassing situation where either they could not be displayed normally or the image was severely deformed at the north and south poles, resulting in a large reduction in picture utilization; while triangular LED spherical screens have overcome the problems of displaying the north and south poles of watermelon skin screens, but they also faced a series of difficult shortcomings such as a wide variety of PCBs, difficulty in reducing the dot spacing due to the honeycomb arrangement of pixels, and complicated software writing.

At present, the common LED spherical displays on the market mainly focus on three types: watermelon ball screens, triangular football screens and six-sided ball screens. As the first ball screen to appear on the market, the watermelon skin LED spherical screen shows the advantages of intuitive structure and fewer types of PCBs with its watermelon skin-shaped PCB composition. However, the display problem of the north and south poles has become an insurmountable gap. After all, the pixel points are arranged not in rows and columns but in circles, which is contrary to the pixel point arrangement rule of conventional image sources, making it unable to perform image presentation. Although the triangular LED spherical screen relies on the unique structure composed of a planar triangular PCB to improve picture utilization, its own limitations limit its development.

As a rising star, the six-sided LED spherical screen uses a quadrangular PCB to create a unique LED spherical screen,"" gradually emerging in the name of the six-sided LED spherical screen. Its layout is closer to the flat LED display, and the minimum dot spacing is almost unlimited. It can easily achieve an effect similar to that of the flat LED display. Compared with the spherical screen composed of a triangular PCB, the advantages are fully demonstrated. It cleverly divides the entire spherical surface into 6 identical surfaces, and each surface is further refined into 4 identical unit boxes, making a total of 24 unit boxes. Each unit box is assembled by 16 PCBs welded with LED lights. Finally, an LED spherical screen with excellent performance has been built, which has undoubtedly injected new vitality into the field of LED spherical screens, and also allows us to see the light of hope that display technology will continue to advance through continuous exploration and optimization.
