Abstract: A liquid crystal display (1) includes a liquid crystal panel (10) including pixel units, a digital video card (14), a regulator (12) and a controller (13). The digital video card is configured for sequentially generating video signals. The regulator is configured for generating modulated video signals and generating a black-inserting signal. The controller is configured for receiveing the source video signals, the modulated video signals and the black-inserting signal, and selectively outputting the source video signals, the modulated video signals and the black-inserting signal to the pixel units during each frame.

Abstract: An exemplary method for driving a typical liquid crystal display (2) with a matrix of pixels (205) includes the steps of: (a) applying video signals with a first polarity pattern to the pixels during a frame period, (b) re-defining the first polarity pattern by sequentially shifting the polarity sequences of one row to an adjacent row within a 2K-by-2K square sub-matrix of the pixels; (c) applying video signals with the re-defined first polarity pattern to the matrix of pixels during next frame period; and (d) repeating steps (b) and (c).

Abstract: An exemplary driving circuit (250) of an LCD (200) includes: gate lines (210) that are parallel to each other and that each extend along a first direction; data lines (202) that are parallel to each other and that each extend along a second direction substantially orthogonal to the first direction; a gate driving circuit (210) connected to the gate lines; a data driving circuit (220) connected to the data lines; and a pre-charging voltage circuit (240). The pre-charging voltage circuit is configured to provide a pre-charging voltage to each of the data lines before the gate driving circuit scans the gate lines.
