Abstract: A display apparatus includes a display panel and a driving circuit. The display panel includes pixels. Each of the pixels is connected to one of gate lines and one of data lines. The driving circuit drives the gate lines and the data lines to display an image on the display panel. The driving circuit alternately provides a first polarity data driving signal and a second polarity data driving signal to each of the plurality of data lines. During an asymmetrical mode, the first polarity data driving signal is provided to first data lines of the data lines during a first frame period before a blank period begins, and the second polarity data driving signal is provided to the first data lines during a second frame period after the blank period ends. The second frame period excludes the blank period.

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 device includes a driving controller controlling a data driving circuit and providing a clock signal and a driving voltage in response to an image signal and a control signal received from an external source. The driving controller restores a data enable signal having a display period and a blank period in one frame on the basis of the control signal and sets a voltage level of the driving voltage applied to the gate driving circuit in accordance with a duration of the blank period. During a sequence of frames having a changing frame rate, the driving voltage for each respective frame may be set based on the duration of each respective blank period.
