With the gradual increase in the demand for creative display, the conventional rectangular led display can no longer meet people's needs for advertising display, so many manufacturers began to actively develop more creative display led shaped display, among which, the spherical led display is one of the very best-selling style, the market common led spherical screen there are three main types.The difference is the six-sided ball screen, the football screen and the watermelon ball screen.

1.Watermelon peel led spherical screen

The earliest led spherical screen on the market is called the watermelon shell spherical screen, which is composed of a PCB similar to the watermelon shell shape, characterized by a very intuitive structure, less PCB types need to be used, but it also has a more obvious disadvantage, that is, the image can not be played normally at the north and south poles, so the use rate of its screen is relatively low. The image will also appear a certain deformation, because now all the image source pixels are arranged in rows and columns, but the pixels of the north and south poles of the watermelon shell led spherical screen are not arranged in rows and columns but in circles, so it is difficult to display;

2.soccer ball shaped led spherical screen

The main component is the triangular PCB board, this spherical screen is also known as the football screen, which has overcome the shortcomings of the watermelon skin led spherical screen that can not play images at the north and south poles, so the screen utilization rate has been improved a lot, but there are also some shortcomings, that is, there are more types of PCB, which is limited by the pixel point honeycomb deployment. This kind of led spherical screen generally needs to be larger, and the software writing is also very troublesome;

3. Six-sided led spherical screen

This is a relatively new product, there are quadrilateral PCB board composed of led spherical screen, pixel distribution is closer to the conventional rectangular led display, pixel spacing can be close to the conventional screen, basically without too much limitation, the effect is better, the entire led spherical screen outside the surface is divided into a shape and size exactly the same surface,Then each surface is divided into four unit boxes of the same shape and size, six faces a total of 24 unit boxes, each unit box is composed of 16 PCB welded with led lights on the surface, and finally assembled into an led spherical screen. The PCB board type of the six-sided led spherical screen is relatively small, and the pixel distribution is closer to the conventional led display, so as long as the content that can be played on the conventional display screen can basically be used directly on the six-sided led spherical screen, compared with the other two led spherical screens, the display effect will be much better;

The above is the main three types of full-color led spherical screen with the design structure, engineers after years of unremitting efforts, continuous process improvement, the conventional display module is currently applied in about 100 special-shaped display, in order to ensure the display effect and protection at the same time, but also greatly improve the service life of the product, and effectively reduce the overall production cost.
