1. A display control method for a display control device of a display apparatus, comprising:
determining a data stream format of a tth frame of image according to received data streams for the tth frame of image, wherein the data stream format comprises an entire frame transmission format and a regional transmission format, the entire frame transmission format is used for transmitting data for entire frame of image, and the regional transmission format is used for transmitting image data for a dynamic region with refreshed content, t being an integer greater than 1;
determining the dynamic region and the image data for the dynamic region in the tth frame of image from the received data streams for the tth frame of image in response to that the data stream format of the tth frame of image is the regional transmission format, wherein the tth frame of image further comprises a static region in addition to the dynamic region; and
transmitting the image data for the dynamic region in the tth frame of image and/or image data for a (t−1)th frame of image in a buffer space of the display control device to a display assembly of the display apparatus according to an end-of-transmission identifier in the data streams for the tth frame of image and a configuration command of the tth frame of image, so that the display assembly refreshes the display image,
the regional transmission format comprises a plurality of pixel segments of the image data for the dynamic region, a plurality of regional end-of-transmission identifiers indicating that transmission of the image data for the dynamic region in the tth frame of image is finished, and an entire frame end-of-transmission identifier indicating that transmission of image data for the tth frame of image is finished, wherein
each of the plurality of pixel segments is followed by a corresponding one of the plurality of regional end-of-transmission identifiers.
