The full-color spherical LED display screen is mainly used in museums, science and technology museums, enterprise exhibition halls, exhibition halls, outdoor spherical video ads, spherical lighting projects and other places. The spherical LED display screen can not only play video ads, brand publicity, but also do decorative lighting. The installation methods are diversified, including sitting, hoisting, inlaid, embedded and other installation methods to meet the installation needs of different customers. The spherical led display screen allows the audience to view 360 ° from a full angle. Unlike the conventional led display screen, the picture details are easy to display. At the same time, the spherical led display screen can directly project the earth, football and other spherical objects onto the display screen, giving people an intuitive and perfect video enjoyment.
LED spherical screen
Basic principle of LED spherical screen:
It is composed of core control module, rotary display module, wireless module, character library module, motor drive module and power supply. The fan leaf is designed as a circle, with a circle of LED beads on it. The LED light is monochrome or multi-color. When the fan leaf rotates around the central axis, a spherical surface will be generated, and all the spherical surfaces are LED. With the font software, when the fan leaf reaches the corresponding position, the corresponding point will be lit, so that the display content of a spherical surface can be controlled.
Watermelon peel ball screen
1. The first spherical screen on the market, commonly known as watermelon peel spherical screen, is composed of watermelon peel shaped PCBs. Its advantages are easy to make, few types of PCBs are available, the threshold for entry is low, and its popularity is fast. Its disadvantages are that the North South bipolar (or 45 ° north latitude, 45 ° south latitude) cannot broadcast images, so the image utilization rate is too low.
Football screen
The ball screen composed of a plane triangle PCB, commonly known as the football screen, overcomes the disadvantage that the north and south poles of the watermelon skin ball screen cannot play images, and greatly improves the image utilization. The disadvantage is that there are many kinds of PCBs, and the spacing between pixels is restricted to be no less than 8.5mm due to the honeycomb layout of pixels. Therefore, software writing is also troublesome, and the technical threshold is too high.
