Patent attributes
A liquid crystal display and a driving method therefor comprises a plurality of pixels arranged in a matrix; data lines and gate lines connected to the pixels; a signal controller processing first image data and a plurality of control signals from an external device and transmitting the processed first image data and control signals; and a data driver connected to the signal controller, wherein the signal controller divides the first image data into and sequentially processes a plurality of sets respectively including the first image data for at least two pixel rows, while delaying the remaining image data excluding the last image data among the first image data of each of the sets, and the data driver applies a charge sharing voltages as impulse voltages to the predetermined number of pixel rows during the delayed time, thereby displaying impulse images. In this way, since impulse images are displayed only by delaying image data within the same time and separate black image data are not transmitted, the data transmission frequency is not increased.
