Description
Technical field
The present invention relates to fan screen field of display technology more particularly to it is a kind of splice fan screen display methods and its
System.
Background technique
In quick movement, after the image that human eye is seen disappears, human eye remains to continue to retain its image 0.1- object
0.4 second or so image, this phenomenon are referred to as visual persistence phenomenon.When human eye watches object, image on retina, and by
Optic nerve inputs human brain, feels the picture of object.But when object is removed, optic nerve will not disappear to the impression of object immediately,
And to continue 0.1-0.4 seconds time, this property of human eye is referred to as " persistence of visions of eyes ".
Visual persistence phenomenon is used by Chinese first, and revolving horse lantern is according to persistence of vision fortune earliest in historical records
With.Have revolving horse lantern when the Song dynasty, claimed " horse rides lamp " at that time.Subsequent Frenchman sieve Borrow, which is covered, invented thaumatrope in 1828,
It is the disk passed through by rope on two sides, and the one side of disk has drawn a bird, and another side has drawn an empty cage.Work as circle
When disc spins, bird occurs in cage, this demonstrate that it once retains an image when eyes see a series of images.
Likewise, fan screen shows 3D rendering also with visual persistence effect.
Splice fan screen in the prior art, since fan screen and traditional monitor are in difference physically, Yi Ji
