Description
Technical Field
The invention relates to the technical field of fan screen display, in particular to a fan screen display control method and a fan screen display control system based on a Linux system.
Background
When the object moves rapidly, after the image seen by human eyes disappears, the human eyes can still keep the image of the image for about 0.1-0.4 second, and the phenomenon is called persistence of vision. When the human eye views an object, the image is formed on the retina, and the optic nerve inputs the image into the human brain, so that the image of the object is sensed. However, when the object is removed, the impression of the object by the optic nerve does not disappear immediately, but lasts for a period of 0.1-0.4 seconds, and this property of the human eye is called "ocular persistence".
The phenomenon of persistence of vision is first used by Chinese people, and the trotting horse lantern is the earliest persistence of vision in history. In Song Dynasty, a trotting horse lamp was known and was called "riding horse lamp". Subsequently, in 1828, the French Paul canopy invented a shadow disc, which was a disc threaded on both sides by a rope, one side of the disc depicting a bird and the other side depicting an empty cage. When the disc was rotated, the birds appeared in the cage, demonstrating that when the eye sees a series of images, it retained one image at a time. Similarly, the fan screen displays 3D images using the effect of persistence of vision.
In the fan screen display system in the prior art, when the fan screen is rotated for display, pictures to be displayed in advance or videos in various formats need to be coded and recombined, that is, data needs to be firstly converted into formats which can be recognized by LED lamp beads of the fan screen off line and then displayed through TCON, so that the universality is poor, a display algorithm needs to be known for displaying on the fan screen, or coding conversion software provided by an equipment provider is used for converting the data into a supported format so as to normally output and display, and the user experience is poor.
