Abstract

The invention discloses a control system of an extra large LED (Light-Emitting Diode) display screen, which comprises a PC (Personal Computer), a control unit and an LED display screen, wherein a receiving module is arranged on each LED box body of the LED display screen; the control unit comprises a processing module, a transmitting module, a checking module and an analog feedback module; a fixing slot for fixing and connecting the control unit is arranged in the PC; the processing module is used for processing a video signal to generate control signals of each LED box body, and the control signals are respectively transmitted to the checking module and each receiving module through the transmitting module; the checking module is used for checking each control signal, and the analog feedback module is used for restoring and displaying the video signal on a display device of the PC; and at least one sensing unit is arranged on the two mutually connected LED box bodies and is used for sensing the connection flatness of the two LED box bodies and outputting the flatness data to the PC. The control system provided by the invention has a simple structure, can monitor the display of the LED display screen according to analog feedback and has high installation flatness.

Description

technical field [0001] The invention relates to a control technology of an illuminating device, in particular to a control system of a super-large LED display screen. Background technique [0002] With the holding of large-scale events such as the World Expo and the Asian Games in my country, it has provided a good display platform for China's LED industry. LED displays have played a more important role in large-scale events and important occasions. The reliability and stability of display applications are extremely important. [0003] In the prior art, due to the large number of parts and complex installation structure of large LED display screens, failure of any small part or uneven installation will affect the display of the entire screen. There are many components, and its control system is also relatively complicated. [0004] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0005] The technical problem to be solved ...
