Technical Field

The invention relates to the field of POV (point of view) LEDs (light emitting diodes), in particular to a fan-type rotary 3D display device.

Background

The POV (Point of View) LED uses the principle of human visual persistence, uses a few (can be a column) LEDs and a motor to replace a dot matrix to display characters or images, and can display preset characters or patterns by accurately controlling the rotating speed of the motor and the lighting and extinguishing time of the LED, and some LEDs can also play set videos. Because the number of the LEDs is greatly reduced, the failure rate of the dot matrix screen caused by the damage of the LEDs is greatly reduced, and the maintenance is more convenient. In addition, the rotating LED display screen using the pocled principle has a wider viewing angle, almost 360 degrees without dead angle.

The fan drives air to flow to form wind to bring cool feeling to people through the rotation of the fan blades, one or more rows of LEDs are arranged on one or more fan blades along the radial direction of the fan to form a 3D fan device for advertising and playing entertainment programs, and people can watch advertisements and enjoy the entertainment programs while enjoying cool. The Chinese invention grant publication No. CN 201763639U discloses a rotary display electric fan, which comprises fan blades, wherein a control circuit board is fixedly installed on the fan blades, a display module formed by LED lamps arranged longitudinally is arranged on one surface of the control circuit board, which faces the fan blades, and the display module is arranged on the front surface of the fan blades. The display module is arranged on the fan blades of the product, so that the fan blades can not only bring the effects of blowing and cooling to people when rotating, but also display different characters and patterns under the control of the single chip microcomputer chip, and the display module is novel, practical and attractive in appearance; when the temperature sensing module is arranged, the display can display the current temperature value along with the rotation of the fan blades. However, the installation modes of the existing rotary display electric fan are basically a wall-mounted type and a floor type, the angle cannot be adjusted, the electric fan is inconvenient to use in various scenes, and the requirements of people cannot be met.
