Abstract: A controller for a display panel includes a detector, a timing controller, and a voltage generator. The detector detects a predetermined pattern in an image signal. The timing controller generates a control signal based on detection of the pattern. The voltage generator changes at least one driving voltage for a display panel from a first level to a second level based on the control signal. The predetermined pattern may correspond to at least one region having a predetermined arrangement of at least first and second gray scale values of pixels in an image corresponding to the image signal.

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.
