    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 display apparatus includes a timing controller, a data driver and a display panel. The timing controller generates a mode selection signal and output image data in response to input image data. The data driver generates first through N-th data voltages in response to the mode selection signal and the output image data and applies the first through N-th data voltages to first through N-th data lines. The display panel is connected to the first through N-th data lines. During the first operation mode, each of a polarity pattern of first through M-th data voltages and a polarity pattern of (M+1)-th through N-th data voltages repeats a first polarity pattern. During the second operation mode, the polarity pattern of the first through M-th data voltages repeats the first polarity pattern, and the polarity pattern of the (M+1)-th through N-th data voltages repeats a second polarity pattern.
