Full-color spherical LED display is mainly used in museums, science and technology museums, enterprise exhibition halls, exhibition halls, outdoor spherical video advertising, spherical lighting projects and other places. Lighten up. Various installation methods can be provided, such as floor type, lifting type, Mosaic type, embedded type, etc., to meet the installation needs of different customers. The spherical LED display gives viewers a 360 degree view. Unlike the traditional led display, the details of the picture are easy to show. Meanwhile, the spherical led display can directly project spherical objects such as the earth and football onto the display screen, giving people an intuitive and perfect video enjoyment.

The basic principle of LED spherical screen:

It consists of a core control module, a rotating display module, wireless module, font module, motor drive module, power supply. The blade is designed as a circle with a circle of LED beads. Leds emit in monochromatic or multicolor colors. When the fan blade rotates around the central axis, a sphere is generated. All the spheres are LED. With the font software, when the fan blade moves to the corresponding position, the corresponding point will light up, so that the content of the sphere can be controlled.

The earliest ball screen on the market, commonly known as watermelon skin ball screen, is composed of watermelon rind PCB. Poles (or 45° north, 45° south) cannot play images, so picture utilization is too low.

The spherical screen composed of flat triangular PCB, commonly known as the football screen, overcomes the shortcomings of the watermelon skin screen that can not play images at the north and south poles, and greatly improves the utilization rate of the screen. The disadvantage is that there are many kinds of PCB, and the pixels are limited by the honeycomb arrangement, so the spacing between the pixels cannot be less than 8.5mm. So writing software is more troublesome, the entry technical threshold is too high.

The most recent spherical plate composed of quadrilateral PCB is called hexahedral spherical plate. It also has fewer PCB board types than soccer screens. The entry barrier is relatively low, the layout points are closer to the flat LED display, and the minimum point spacing is similar to the flat LED display, with little or no restrictions, so the effect is much better than the composed spherical screen triangular PCB. In terms of physical size, the whole sphere curtain is composed of 24 spheres of the same size. It can be put into the air box, which is very convenient to disassemble and assemble, convenient for renters to use. When playing back, a ball screen is divided into 6 identical screens, namely up, down, left, right, front and back. Of course, different video sources can also be played individually or in combination with software. As a result, it plays far better than watermelon and soccer screens.
