Polarity reversion driving method and apparatus of liquid crystal display, and a liquid crystal display
Polarity reversion driving method and apparatus of liquid crystal display and a liquid crystal display are provided. In the method, four frames constitute one polarity reversion driving period, in which a first frame and a third frame have a same polarity arrangement with reversed polarities; a second frame and a fourth frame have a same polarity arrangement with reversed polarities; the first frame and the second frame have different polarity arrangements and corresponding pixels in adjacent two frames have complementary charging effects. The apparatus includes a time schedule controller, a logic controller and a source driver. Charging effects of pixels in frames are controlled by setting a polarity arrangement of pixels in each frame so that charging effects of corresponding pixels are complementary in adjacent two frames, thereby relieving the problem of reduced display quality due to inconsistent charging effects of pixels on two sides of data lines.
