Display device and cascade control method

A display device, comprising a plurality of display modules, wherein each of the plurality of display modules comprises a display component and a signal processing component;

• and the plurality of display modules comprise a first display module, the first display module comprising a first display component, a first signal processing component, and a first adjusting circuit;
• wherein the first display component is connected to the first signal processing component, the first adjusting circuit is electrically connected with a first processor and the first display component, or the first adjusting circuit is disposed in the first processor;
• the first adjusting circuit is configured to adjust a display parameter of the first display component according to target control information in modulation information;
• and the first signal processing component comprises a first communication interface, a second communication interface, and a first processor;
• wherein the first processor is configured to determine, according to a cascade rule of the plurality of display modules, address information of display modules other than the first display module, and output the address information of other display modules via the second communication interface;
• the first processor is further configured to assign, in response to an address assignment instruction received by the first communication interface, address information to the first display module;
• acquire, in response to the modulation information, target address information in the modulation information;
• and determine whether the target address information is consistent with current address information of the first display module, if yes, acquire the target control information, and if not, output the modulation information to other display modules via the second communication interface for other display modules to determine whether their address information is consistent with the target address information.
