Abstract: A display device and a driving method thereof are disclosed. In one aspect, the display device includes a display panel including a plurality of pixel rows, a data driver configured to transfer data voltages to the display panel, a gate driver configured to transfer gate signals to the display panel, and a signal controller configured to control the data driver and the gate driver. The pixel rows are divided into i (i is a natural number of 2 or more) pixel row groups including a plurality of pixel rows, respectively. The display panel displays one still image for one frame set including the i sequential frames, and each of the i pixel row groups is charged by receiving the data voltage for each frame of the frame set, and the frames in which the i pixel row groups are charged are different from each other.

Abstract: A display device includes a signal controller and a data driver. The signal controller processes an input image signal to generate an output image signal. The signal controller processes the input image signal using a correction unit. The correction unit corrects the input image signal to a first gray scale value greater than 0 gray scale value when the gray scale value of the input image signal is 0. The output image signal is based on the corrected input image signal. The data driver converts the output image signal into a data voltage to be applied to a display panel.

Abstract: A display apparatus includes a display panel, a driving controller and a data driver. The driving controller processes input image data according to a variable input frequency and generates a data signal having a varied frame length. The data driver converts the data signal into a data voltage and outputs the data voltage to the display panel. The driving controller determines a variable frequency mode and generates an asymmetric data signal including a positive data signal and a negative data signal which are asymmetric with respect to a common voltage for a same grayscale value in the variable frequency mode.
