    Abstract: A display driver integrated circuit is provided which includes a first line buffer which receives first pixel data of an odd lane in response to an external clock and outputs the first pixel data in response to an internal clock; a second line buffer which receives second pixel data of an even lane in response to the external clock and outputs the second pixel data in response to the internal clock; a line buffer controller which receives display data by the two pixel data to output the first and second pixel data; a data merger which merges the first pixel data output from the first line buffer and second pixel data output from the second line buffer; and an image data processing block which processes the merged pixel data, wherein a frequency of the internal clock is lower than a frequency of the external clock.

    Abstract: A display driving circuit includes first through (2*n)-th buffers, a buffer controller, first through n-th image processing units, and a source driver. The buffer controller circularly selects one of the first through (2*n)-th buffers in an order from the first buffer to the (2*n)-th buffer at each of a plurality of first time intervals, and stores pixel data received during the first time interval in the selected buffer. Each of the first through n-th image processing units is coupled to two corresponding buffers among the first through (2*n)-th buffers, and processes the pixel data, which are stored in at least one of their corresponding buffers, during n of the first time intervals to generate processed data when the pixel data are stored in the corresponding buffer during the first time interval. The source driver generates analog signals based on the processed data.
