Nowadays, the competition of traditional LED display screens is becoming more and more fierce, and the emergence of spherical display screens has undoubtedly attracted the attention of all consumers. The spherical display screens we can see usually include a watermelon ball screen, a football screen and a six-sided ball screen. So what's the difference besides the spherical display?
The playback principle of the LED display is that the control system (controller + computer) of the display transmits the image source played on the computer screen to the flat LED display for display. If the diameter of the spherical screen is sufficiently large, the effective attention is probably only about one-sixth of the surface area of the sphere, so the flat image source sent to the three-dimensional spherical screen for display needs to be processed. In this way, dividing the same image source into different image sources, and then assigning them to different areas for playback, is the playback principle of the spherical screen.
The resolution design of the LED spherical screen is the same as that of the flat LED display, that is, it is closely related to the viewing distance of the LED display. But because of the particularity of the spherical screen, the viewing distance is different from the ordinary flat LED display. At this time, the calculation of the suitable viewing distance requires a combination of two factors, the horizontal distance and the vertical angle between the human eye and the spherical screen. Especially the spherical screen placed indoors should pay attention to the calculation of the actual viewing distance, so as to achieve the expected display effect.
In addition to appearance, display principle and viewing distance, different led spherical screens have different display characteristics. However, with the development of science and technology, people believe that more spherical screens that meet the viewing needs of the audience will satisfy everyone.
