  • detecting a first update region where a display image is to be updated;

    determining a first determination to update a partial frame included in a whole frame on a display based on the first update region being completely contained within a predefined partial frame region, wherein the predefined partial frame region is less than a whole frame region;

    receiving a first indication signal indicating a first data update and corresponding to the first determination to update the partial frame included in the whole frame;

    receiving first data;

    updating the partial frame on the display with an image corresponding to the first data based on the first indication signal corresponding to the first determination to update the partial frame;

    detecting a second update region where the display image is to be updated;

    determining a second determination to update the whole frame based on at least a portion of the second update region being outside of the predefined partial frame region;

    receiving a second indication signal indicating a second data update and corresponding to the second determination to update the whole frame;
