Along with the development of the LED display industry, miniaturization and small spacing are important development trends, and the LED display screen is more widely applied to indoor display occasions, exhibition halls and other display occasions. Meanwhile, the demand for low power consumption of the display screen is more and more strong, and due to the hardware characteristics of the LED display screen, the power consumption of the LED display screen in standby (i.e. displaying black pictures) is generally higher, and the power consumption mainly comes from: lamp panel driving, FPGA processing, ethernet transmission and the like.
In the related art, the power supply is turned off, that is, the LED display screen is directly powered off when not in use, and then the screen power supply is turned on when in use, wherein the power supply is turned off and turned on generally by manual or program control.
