Resolution Design of Spherical LED Display
Resolution design of outdoor ball screen
Its design is the same as that of the flat LED display, that is, it is closely related to the viewing distance of the LED display. The general experience is that the viewing distance is P2.5, 2.5m away, and P6 is 6m away. If it is a P20 outdoor screen, then the viewing distance is 20m. Looking at it from the outside, it is also the same in actual use. This is a relatively vague concept, which is qualitative rather than quantitative. Its basis is expressed as follows:
The LED display screen is the same as the display screen of the computer. The images they display are composed of pixel points, and each pixel point is composed of red, green and blue color elements. There is a certain distance between pixels, which we call the point pitch PH.
Assuming that the resolution of the computer display screen is 1024×768, the computer display screen has 1024 pixels in the horizontal direction and 768 pixels in the vertical direction, for a total of 786432 pixels. It is enough to express a very delicate image.
