    Abstract: A display apparatus includes a display panel, a timing controller, a data driver, and a gate driver. The timing controller receives image data at a number of frames per second of a first level and generates a gate control signal and a data control signal. The timing controller includes an image converter that operates in film mode or normal mode when the input image data are moving image data, and that outputs film image data at a number of frames per second of second level lower than the first level during the film mode. The data driver applies a data voltage corresponding to the film image data to the display panel based on the data control signal. The gate driver applies a gate voltage to the display panel based on the gate control signal. The display panel operates at a frequency of the second level during the film mode.

    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.
