    Abstract: A display device includes a display panel, a data driver which provides data voltages to the display panel, and a controller which provides output image data to the data driver. The controller includes a data line memory which stores input image data for each pixel row of the display panel, an address line memory which stores addresses for the input image data, and a data serialize block which generates the output image data provided to the data driver by rearranging the input image data stored in the data line memory based on the addresses stored in the address line memory.
