Image display method and display apparatus

A display apparatus, comprising:

• a screen configured to display an image;
• a user interface configured to receive a command from a user;
• a communication device configured to communicate with an external device according to a predetermined protocol;
• a memory configured to store computer instructions and data associated with the display apparatus;
• at least one processor, connected to the screen, the user interface, the communication device and the memory, and comprising a first processor and a second processor;
• a first control system, a second control system, and a switch device;
• wherein:
• the screen comprises N display areas;
• wherein N is an integer greater than 1;
• the first control system comprises:
• the first processor and N first control modules;
• wherein the N first control modules are connected in series to form a first serial link, the first processor is connected to one end of a 1st first control module in the first serial link;
• each of the N first control module is connected to a display component of the screen in a corresponding display area through the switch device;
• the N first control modules correspond one-to-one to the N display areas;
• the second control system comprises:
• the second processor and N second control modules;
• wherein the N second control modules are connected in series to form a second serial link, and the second processor is connected to one end of a 1st second control module in the second serial link;
• each of the N second control module is connected to a display component of the screen in a corresponding display area through the switch device;
• the N second control modules correspond one-to-one to the N display areas;
• a display area corresponding to a i-th first control module in the first serial link is same as a display area corresponding to a (N−i+1)th second control module in the second serial link;
• i is an integer greater than or equal to 1 and less than N;
• the i-th first control module in the first serial link is configured to execute the computer instructions to enable the display apparatus to:
• detect whether a (i+1)th first control module in the first serial link has an abnormality;
• based on that the (i+1)th first control module has an abnormality, send indication information indicating that the (i+1)th first control module has an abnormality to the first processor and the second processor through the switch device;
• the first processor is configured to execute the computer instructions to enable the display apparatus to:
• in response to the indication information, control display areas corresponding to the 1st first control module to the i-th first control module in the first serial link to display an image;
• the second processor is configured to execute the computer instructions to enable the display apparatus to:
• in response to the indication information, control display areas corresponding to the 1st second control module to a (N−i)th second control module in the second serial link to display an image.
