First, the LED ball screen production method:
1. For a large-diameter outdoor spherical LED screen, a single-pixel tube can be used. The ball is cut in latitude, one row of LED pixel tubes is placed at each latitude.
2. For a small-diameter indoor spherical LED display, a three-in-one surface-mounted LED lamp can be used, and a point-by-point controllable light strip can be manufactured using a flexible PCB board. Then the lamp strip, like the first form, surrounds the sphere by latitude.
3. For indoor screens, special LED cell boards can also be designed according to the dot spacing. Shaped cell board can be designed to be spliced ​​in triangles, or can be designed to be spliced ​​in 6-sided shape (just like soccer, it is made up of multiple 6-sided polygons). The types of indoor LED spherical display screens are: P4, P5, P6, P10 and other models to choose from.
No matter what kind of method is used to produce spherical LED display screens, special LED display screen control systems are needed. In the control, it is necessary to do special-shaped processing, and it is necessary to do sampling processing. Therefore, the cost of spherical LED display screens is much higher than that of ordinary display screens.
Second, the outdoor ball screen resolution design
Its design is the same as the flat LED display, which is closely related to the viewing distance of the LED display. The general experience is P2.5, 2.5 meters away, P6 6 meters, if it is P20 outdoor screen, then in 20 meters In addition to viewing it, it is also true that it is used in reality. This is a relatively vague concept, qualitative rather than quantitative, and its basis is expressed as follows:
The LED display is the same as the computer's display. The images they display are composed of dots. Each pixel consists of red, green, and blue color elements. There is a certain distance between the pixel and the pixel. This distance is called the dot pitch PH. Set the resolution of the computer display to 1024×768, the computer display has 1024 pixels in the horizontal direction, 768 pixels in the vertical direction, a total of 786,432 pixels. It is enough to express a very delicate image.
Spherical LED display manufacturing process and resolution design
Outdoor spherical LED display is a brand new product, wherever it gathers the focus of popularity. In the production, what is special about the LED ball screen?
