The invention discloses an array baseplate, preparation and driving methods thereof, and a liquid crystal display panel, so as to lower driving pressure for a liquid crystal display device and increase light permeability. The array baseplate comprises data lines and grid lines vertically and transversally crossed to form a plurality of pixel units; each pixel unit comprises a pixel electrode and a common electrode; the common electrodes comprise first common electrodes and second common electrodes; the first common electrodes, the second common electrodes, and the pixel electrodes are in the same layer; the first common electrodes and the second common electrodes are in strip-shaped patterns; the first common electrodes, the pixel electrodes, and the second common electrodes are mutually arranged at intervals; the first common electrodes are connected to a first common electrode conducting wire through first contact holes; the second common electrodes are connected to a second common electrode conducting wire through second contact holes; and the first common electrode conducting wire and the second common electrode conducting wire are parallel with the grid lines.
