摘要： 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.

摘要： A display apparatus includes a timing controller and a display panel. The timing controller generates output image data based on input image data and generates a polarity control signal by analyzing the input image data. The display panel displays a plurality of frame images based on the output image data during a plurality of frames and operates based on an inversion driving scheme in which a polarity pattern of the plurality of frame images is changed based on the polarity control signal per N frames, where N is a natural number. The number N is variable based on the polarity control signal.

摘要： A display apparatus includes a display panel, a first timing controller, a second timing controller and a third timing controller. The first timing controller controls an operation of a first region in the display panel, and generates a reference clock signal. The second timing controller controls an operation of a second region in the display panel, and receives the reference clock signal. The third timing controller controls an operation of a third region in the display panel, and receives the reference clock signal. The first, second and third timing controllers are synchronized with one another in response to the reference clock signal and a state synchronization signal, and operate in one of a plurality of states depending on an operation of the display apparatus.
