1. A method of operating a display driving circuit, the method comprising:
receiving an update slice;
writing the update slice to at least a portion of a graphic memory;
decoding the update slice to obtain first decoded data and image-processing the first decoded data to obtain image-processed data;
decoding at least one still slice among a plurality of slices stored in the graphic memory to obtain second decoded data; and
integrating the second decoded data and the image-processed data.
