Principle of rotating fan 3D Hologram Display Fan: it is a new type of naked eye 3D air imaging product that combines fan rotation + LED light bar display and uses the principle of human eye persistence to form graphics, animation and video. Without the help of any equipment, you can see 3D video effects with naked eyes.
During the imaging of 3D Hologram LED Fan, all LED lights shine, and the surrounding shell is dark and will not shine. In this way, during the operation of 3D Hologram Fan, the human eye will only receive the stay of light, while the dark without light will be too fast to be distinguished by the brain. In this way, the display effect will only stay on the light displayed by LED lights, so as to achieve the effect of aerial imaging, and then present 3D floating images.
The working principle of 3D Hologram Display Fan is mainly to use the persistence factor of human vision (POV Technology), through a column or several columns of LED dense arrangement and then rotating imaging.
To be specific, the visual effect of light on the retina will remain for a period of time after the light stops working. Although the recognition accuracy of the human eye is very high, the time required for the optical nerve to transmit the image to the brain is 1/24 second. It is with this factor that a continuous picture can be formed when the switching speed of multiple freeze frames reaches 24 frames (the 24 frames referred to here are the frame rate directly displayed to the human eye, rather than the frame rate transmitted by the picture to some machines).
The frame rate of 3D Hologram LED Fan is generally about 30 frames per second, that is to say, the freeze frame time of each picture is 1/30 second, so the imaging effect is achieved.
At the same time, when the equipment is imaging, all LED lights are emitting light, and the surrounding shell is dark and does not emit light, so during the operation of the equipment, the human eye will only receive the stay of light, while the dark and unlit will be too fast to be distinguished by the brain, so the display effect will only stay on the light shown by the LED, so as to achieve the effect of aerial imaging. Then use the material with 3D effect, so as to realize the effect of holographic 3D imaging.
