ABSTRACT:
A liquid crystal display (300) includes a liquid crystal panel (310) having a plurality of pixels P(i,j)arranged in a matrix, a brightness identification unit (343) configured for identifying a brightness of an image element to be displayed by at least one pixel, a polarity analyzing unit (344) configured for analyzing a result of the identification, and a data circuit (330). The polarity analyzing unit is also configured for generating a composed binary signal having a first binary portion the same as the primary display signal and an additive second binary portion. The data circuit is configured to provide a data voltage to drive the pixel according to the signal. A value of the data voltage is determined by a first binary portion of the composed binary signal, and a polarity of the pixel is determined by the second binary portion of the composed binary signal.
