DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

The present invention relates to a display device and a driving method thereof. The display device according to an embodiment of the present invention comprise: a plurality of gate lines; a plurality of data lines; a plurality of pixels comprising a switching element connected to the gate lines and data lines; a data driver; a gate driver; and a signal controller for controlling the data driver and gate driver. The method for driving the display device comprises the steps of: generating output image data by compressing, by the signal controller, vertical resolution of input image data of first frame by 1/k (k is a natural number) or receiving by the signal controller the compressed input image data or receiving and processing, by the vertical resolution, the compressed input image data by 1/k; generating, by the data driver, data voltages based on the output image data and applying the data voltages to the data lines; and applying, by the gate driver, gate-on voltage pulses concurrently to k number of neighboring gate lines corresponding to each image data of the output image data. In the first frame, starting times of applying the gate-on voltage pulses of at least two gate lines of the k number of neighboring gate lines are different from each other. The present invention is designed to soften image edges by lessening the aliasing phenomenon that may occur when vertical resolution is reduced because of gate doubling driving.
