Liquid crystal display device and driving method thereof

Abstract

A liquid crystal display device comprises a display panel; a source driver configured to provide source outputs to the display panel; a memory configured to store polarities of the source outputs with respect to a panel self-refresh operation and a normal refresh operation that is not the panel self-refresh operation as a first inversion pattern and to store the polarities of source outputs with respect to a low refresh rate operation as a second inversion pattern; and an LRR controller configured to control the polarities of the source outputs with the first inversion pattern in panel self-refresh frames before the low refresh rate operation is performed, to control the polarities of the source outputs with a third inversion pattern referring to the first inversion pattern in low refresh rate frames in which the low refresh rate operation is performed, and to control the polarities of the source outputs with a fourth inversion pattern referring to the second inversion pattern in normal refresh frames after the low refresh rate operation ends.
