Abstract
A method of operating a display device involves detecting whether a frame mode of the display device is a normal mode in which image data are received with a constant frame rate or a variable frame mode in which the image data are received with a variable frame rate. An output buffer drivability of a data driver included in the display device may be set according to the detected frame mode, and an image is displayed by outputting data voltages corresponding to the image data with slew rates corresponding to the set output buffer drivability. Power consumption in output buffer amplifiers may be selectively lowered by setting a relatively low output buffer drivability corresponding to a relatively low slew rate.
