Strictly speaking, this so-called "Fan" is just a visual name. In fact, it is a kind of "rotating LED light bar", and its professional name is holographic 3D smart screen. After power-on, the "fan blade" starts to rotate, and at the same time, 3D images can be presented, which is cool and realistic.
At the same time, according to the size and color of the pattern, the LED fan can hide its blades well. Because there is no frame and no fixed screen, the dynamic picture floats like a volley, which is very realistic.
Extended data:
The "electric fan" has become a "display screen", and the employees of Nanjing Tashigi Digital Technology Co., Ltd. have turned their ideals into reality. In Tashigi's product exhibition area, the "electric fans" are spinning rapidly, but these "electric fans" are not used to cool down. According to the relevant staff of Tashigi, these "electric fans" are actually pieces of holographic display screens, also known as "holographic dazzling screens".
Its working principle is not difficult to understand. When the object is moving rapidly, the image seen by human eyes can still keep its image of about 0. 1-0.4 seconds after it disappears. This phenomenon is called visual persistence.
"Holographic dazzle screen" uses this principle to rotate imaging through ultra-high density self-luminous "fan blade" array. Because the core component rotates like an electric fan, many people call it an "LED electric fan".
