1. Triangular LED spherical screen: The ball screen composed of plane triangular PCB, commonly known as football screen. It overcomes the disadvantages of the North and South Pole of the watermelon leather screen, and the use rate of the screen is greatly improved. The disadvantage is that there are many types of PCB. The pixels are not less than 8.5mm for the restrictions of hive -shaped discharge. Therefore, software writing is also more troublesome, and the technical threshold is too high.
2. Watermelon leather LED spherical screen: The earliest screen screen on the market, commonly known as watermelon leather screen. It consists of watermelon skin -like PCB. Its advantages are convenient production. There are few types of PCB. Fast, the disadvantage is that the north -south di poles (or north latitude 45 °, and 45 ° south of the south) cannot play images, so the utilization rate is too low.
3. Six -sided panoramic LED spherical screen: It is a recent quadrilateral PCB screen, which is called a six -sided ball screen. Its types of PCB boards are also less than football screens. The entry threshold is relatively low, and the cloth point is closer to the flat HD LED alien screen. The minimum spacing is similar to the flat high -definition LED alien screen. The limit is not large or almost unlimited. Therefore, the effect is much better than the ball screen composed of triangular PCB.
