摘要： A display apparatus includes a display panel and a timing controller. The timing controller generates first output image data based on input image data and sets a driving frequency of the display panel as a first frequency in a first operation mode. The timing controller converts the input image data into second output image data and sets the driving frequency of the display panel as a second frequency lower than the first frequency in a second operation mode. The display panel displays a first image based on the first frequency and the first output image data in the first operation mode. The first image is represented by X grayscales. The display panel displays a second image based on the second frequency and the second output image data in the second operation mode. The second image is represented by Y grayscales, where Y is less than X.

摘要： A method of driving a display panel and display device including the same are disclosed. In one aspect, the method comprises providing input image data, generating a gamma reference voltage, generating a data voltage based on the gamma reference voltage and input image data, providing the data voltage to the display panel, and determining whether the input image data represents a still image or a video image. The method further comprises substantially periodically and alternately generating first and second common voltages when the input image data represents the still image, and providing the first and second common voltages to the display panel.

摘要： A display apparatus includes a timing controller, a data driver and a display panel. The timing controller receives input image data at a first frequency substantially equal to a frame rate of an input image. The timing controller generates a data signal having the first frequency based on the input image data having the first frequency. The data driver converts the data signal into a data voltage. The display panel displays an image based on the data voltage.

摘要： A display apparatus includes an image analyzer that analyzes image data and outputs an interrupt signal at a period during which the image data of a low frequency change to the image data of a high frequency, a frequency detector that detects the high frequency, a frame rate controller that outputs a vertical synch signal of the high frequency in response to the interrupt signal, a polarity compensation controller that determines a last frame of the low frequency based on an interrupt period at which the interrupt signal is generated, generates a reversed polarity signal with respect to a polarity signal of the last frame and outputs the reversed polarity signal during a polarity compensation period close to the interrupt period, and a data driver circuit that outputs a data signal based on the reversed polarity signal to a data line during the polarity compensation period.
