Problems solved by technology

For example, the patent application number 201410382001.7 discloses a rotating stereoscopic display device, which includes a base, a frame, a rotating shaft, an LED display panel, and a power supply brush. The frame rotates around the rotating shaft, and the distance from the edge of the frame to the rotating shaft is equal. , the LED display board is fixed to the rotating shaft, and the display surface of the LED display board is relatively large. This device is driven by a motor to rotate a large display surface, and requires a large current during operation. On the one hand, it is easy to cause system instability, and on the other hand On the one hand, it wastes electric energy; moreover, if the entire surface is used as the rotating surface, the mass is relatively large, and the energy consumption of the motor is large; the use of brushes for power supply is easy to cause wear and high maintenance costs, and the rotation method of this 3D display device based on array rotation is poor , large wind resistance, instability, high manufacturing cost and difficulty, cannot meet people's demand for low-end and cheap 3D display, and cannot be popularized and used

Abstract

The invention relates to 3D display equipment based on POV. The equipment comprises a base, a supporting unit, a drive motor, an LED bent and an LED control and drive unit, wherein the base comprisesa power source module; the drive motor is fixed on the base by a motor support unit, the upper part of a spindle of the drive motor is connected to a rotation center of the supporting unit, and the supporting unit is connected to the LED bent; and the LED control and drive unit is fixed on the supporting unit to control the drive motor and the LED bent. The equipment is characterized in that the supporting unit comprises supporting arms which are arranged in radial and iso-angle manners; and lengths of the supporting arms are different.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a POV-based 3D display device. technical background [0002] With the advancement of technology, the development of the display field is changing with each passing day, and people's requirements for display effects are getting higher and higher. When watching movies, people generally pursue 3D movies. Similarly, for display devices in life, people generally pursue three-dimensional displayed on the display. However, the current three-dimensional display screen has complex control methods and high manufacturing costs, and is not suitable for displaying some simple three-dimensional patterns, so it is difficult to popularize in daily life. The most common display technology in current life is the flat display technology of LED array, but this array-based display method is only a flat display effect, which cannot meet people's requirements for stereoscopic display. ...
