Display driving method of integrated circuit, integrated circuit, display screen and display apparatus

A display driving method, comprising:

• receiving current boundary pixel data from a first integrated circuit;
• carrying out a sub-pixel rendering calculation on current sub-pixel data stored in a second integrated circuit based on the current boundary pixel data to obtain compensated pixel data;
• and
• transmitting the compensated pixel data to a driven region connected with the second integrated circuit to drive the driven region to display.

A display screen, comprising:

• a first driven region and a second driven region successively arranged;
• and
• a first integrated circuit and a second integrated circuit for respectively driving the first driven region and the second driven region,
• wherein the first integrated circuit is configured to send current boundary pixel data stored in the first integrated circuit to the second integrated circuit, and the second integrated circuit is configured to carry out a sub-pixel rendering calculation on the current boundary pixel data and current sub-pixel data, wherein the current sub-pixel data is stored in the second integrated circuit.
