20 Claims

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;

identifying a type of each slice of a plurality of slices stored in the graphic memory;

decoding the update slice and a standby slice by using a first decoder to obtain first decoded data;

image-processing the first decoded data;

decoding at least one still slice among the plurality of slices stored in the graphic memory by using a second decoder to obtain second decoded data; and

integrating the second decoded data and the image-processed data.
