Display driving method and apparatus, display driver integrated circuit chip and terminal

A display driving apparatus, configured in a display driver integrated circuit (DDIC) chip and comprising:

• a mobile industry processor interface (MIPI) configured to receive a current image frame;
• an adaptive porch controlling component configured to generate a vertical porch corresponding to the current image frame according to a current image transmission speed of an AP;
• and
• a driving component configured to drive a display screen to display the current image frame according to the vertical porch corresponding to the current image frame.

A terminal, comprising:

• a display screen;
• a DDIC chip electrically connected with the display screen;
• and
• an AP electrically connected with the DDIC chip through an MIPI;
• wherein the DDIC chip is configured to drive the display screen to display an image transmitted from the AP by performing acts comprising:
• receiving a current image frame;
• generating a vertical porch corresponding to the current image frame according to a current image transmission speed of an application processor (AP);
• and
• driving a display screen to display the current image frame according to the vertical porch corresponding to the current image frame.
