Display control module and display control method of display device

A display control method of a display device, comprising:

• shielding an initial frame control signal based on an enabled underrun signal to generate a frame control signal which is disabled;
• and
• providing the frame control signal to a plurality of IP core modules;
• enabling an underrun signal based on an image data volume indication signal;
• generating a core module status signal corresponding to statuses of the plurality of IP core modules;
• and
• disabling the underrun signal based on the core module status signal.

A display control method for a display device, wherein the display device includes an image frame streaming path and an image frame stream transmitted on the image frame streaming path, the image frame stream comprises a plurality of image frame, a plurality of processing units are sequentially arranged on the image frame streaming path, the plurality of processing units perform different processing on the same image frame of the image frame stream, each of the plurality of the processing unit receives an image frame frequency signal to sequentially process the plurality of image frames of the image frame stream, each of the plurality of processing units processes a current image frame of the plurality of image frames at a first time point, and the display control method comprises:

• after the first time point, generating a prompt signal when transmission of the image frame stream is uncoordinated on the image frame streaming path;
• generating an image frame frequency disabling signal based on a combination of the image frame frequency signal and the prompt signal;
• and
• for each of the plurality of the processing units, receiving the image frame frequency disabling signal after the first time point, and keeping processing the current image frame based on the image frame frequency disabling signal.
