Rotating LED Spherical Screen is a new type of novel home decoration and subtitle propaganda tool, suitable for decoration of home, car, entertainment, etc. It is also suitable as a publicity display tool for supermarkets, hotels, shops, large squares, etc. Its main purpose is to be able to view the content displayed on the screen in 360 degrees, giving people a three-dimensional viewing effect and bringing beautiful enjoyment to the audience.
First, the basic ideas
1. Develop a new stereo display screen with a minimum of LEDs, you can enjoy the display content from all directions, and the power consumption is low!
2. Design a medium-sized dot matrix screen, which can change the content of the screen display anytime and anywhere by wireless without disassembly, as easy as writing a normal LCD screen.
3. It is convenient to make the screen content static, zoomed or rotated, making the screen more user-friendly.
4. It can be placed horizontally, vertically, and suspended for different users to be fixed to different venues.
5. Design a novel home decoration that creates a comfortable and warm scene that brings a pleasant mood.
Second, the basic principles
This screen consists of a core control module, a rotating display module, a wireless module, a font library module, a motor drive module, a tube positioning module, and the like, a housing, and a power supply.
The rotating fan blade is designed to be circular, and a circle of LEDs is arranged on the fan blade. The color of the LED is monochromatic or multi-color. When the fan blade rotates around the central axis, a spherical surface is generated, and all of the spherical surfaces are generated. It is an LED, with the font software. When the fan leaves to the corresponding position, the corresponding point is illuminated, so that the display content of a spherical surface can be controlled.
Third, the hardware design
Core control module
The core control module adopts STC12C5A60S2 series 1T single-chip microcomputer, and the control module mainly judges the data received by the wireless to perform different actions. It is the control core of the entire screen that processes various data and controls various actions during external periods. As shown in Figure 1.
