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.
