Abstract: A driving controller of a display device controls a scan driving circuit to sequentially drive a first group of scan lines among a plurality of scan lines to an active level during a first low-frequency frame when the operation mode is a low frequency mode and to sequentially drive a second group of scan lines among the plurality of scan lines to the active level during a second low-frequency frame, outputs an image data signal according to a first arrangement order of a plurality of color pixels in a first row during the first low-frequency frame, and outputs the image data signal according to a second arrangement order of the plurality of color pixels in a second row during the second low-frequency frame.

Abstract: A data driver for providing data voltages to a display panel includes a digital-to-analog converting block, an option storing block, a data swap block and an output buffer block. The digital-to-analog converting block converts line data into the data voltages. The option storing block stores a pixel arrangement option representing a pixel arrangement structure of the display panel. The data swap block is connected to the digital-to-analog converting block and the option storing block, and selectively performs a data swap operation that swaps the data voltages based on the pixel arrangement option and whether the line data are odd line data or even line data. The output buffer block is connected to the data swap block and outputs the data voltages on which the data swap operation is selectively performed to data lines.
