The price algorithm for LED spherical screens and LED display screens is the same, both charged based on the sum of squares model. However, spherical screens are generally based on the diameter and model, which is not as complex as the calculation of conventional screen costs. Let’s discuss the types and models of LED spherical screens, and then calculate the cost of making an LED spherical screen.
Watermelon skin ball screen: The earliest ball screen on the market, commonly known as watermelon skin ball screen, is composed of watermelon skin shaped PCBs. Its advantages are convenient production, limited variety of PCBs, low entry threshold, and fast popularization. The disadvantage is that the north-south poles (or north latitude 45 ° north, south latitude 45 ° south) cannot play images, so the screen utilization rate is too low.
Triangle ball screen: A ball screen composed of flat triangular PCBs, commonly known as a football screen, which overcomes the disadvantage of watermelon skin ball screens that cannot play images at the north and south poles, and greatly improves image utilization. The disadvantage is that there are many kinds of PCBs, and the spacing of Restriction point due to the honeycomb layout of pixels cannot be less than 8.5mm. Therefore, software writing is also troublesome, and the technical threshold for entry is too high.
Six sided panoramic ball screen: It is a ball screen composed of quadrilateral PCBs that has only recently emerged, known as a six sided ball screen. It also has fewer types of PCB boards than football screens. The entry threshold is relatively low, and the layout is closer to a flat LED display screen. The minimum point spacing is similar to that of a flat LED display screen, with little or no restrictions, so the effect is much better than that of a ball screen composed of triangular PCBs.
2. The diameter, model, and price of LED spherical screens
The diameter of a LED spherical screen is generally 0.5 meters, 1 meter, 1.2 meters, 1.5 meters, 2 meters, 2.5 meters, 3 meters, and so on.
Spherical screen models: P2, P2.5, P3, P4, where P refers to the distance between two lamp beads, and the following number represents the distance between the dots, which is also the optimal viewing distance.
The price of LED spherical screens is sold as a whole ball, and the actual cost is also calculated based on the square. Generally, the cost is all inclusive, and no other miscellaneous fees are included. Because the price of LED display screen is constantly changing, even if you just say a price now, the final price depends on the market value. It is most convenient to consult the business manager directly.
