The patent abstract shows that this application relates to an LED control device and an LED control system. The LED control device includes: a control component, a switching component, a first interface, a second interface and a cascade interface; the first interface is connected to the first data signal or the second interface is connected to the second data signal; the switching component is connected to the first interface, the second interface and the control component respectively, and is used to transmit the first data signal or the second data signal to the control component; the control component is connected to the cascade interface and the display device respectively, and is used to respond to the first data signal or the second data signal. Control the display device to display; and convert the first data signal into a second data signal and transmit it to the outside through the cascade interface. The sending card and receiving card are replaced by LED control devices. The LED control devices are cascaded in sequence through the cascade interface, thereby simplifying the overall wiring complexity, further avoiding data loss, and improving data transmission stability.
