Variable-speed rotating LED display system and method for displaying the same

Abstract

The invention provides a variable-speed rotating LED display system which comprises an upper computer and an LED display device based on vision duration. The upper computer is used for performing coding preprocessing on to-be-displayed contents in the display range of the display device, obtaining files having been encoded, and transmitting the files having been encoded to the display device in a wireless communication mode. A position sensor of the display device is used for calculating the position posture of a rotating arm, obtaining the accurate posture angle of the rotating arm and transmitting the accurate posture angle to an MCU of the display device. The MCU is used for controlling an LED lamp on the rotating arm in rotating according to the real-time posture angle so that the display device can display brightness-adjustable contents. The variable-speed rotating LED display system greatly improves freedom between the upper computer and the LED display device, meets users' requirements and experience and provides a new development direction for the application of the LED display device.
