摘要： An array substrate (40), a driving method thereof and a display apparatus, relate to a field of display technique. The array substrate (40) comprises a plurality of pixel units (33) arranged in a matrix form and divided by a plurality of crisscrossed gate lines (31) and data lines (32), each of the pixel units (33) comprises pixel electrodes (331) and further comprises common electrodes (332); in the matrix of the pixel units (33), voltage polarities of the common electrodes (332) corresponding to pixel units (33) with a sum of numbers of rows and columns being equal are the same; voltage polarities of the common electrodes (332) of adjacent pixel units (33) are reverse. By adopting the array substrate of such a structure, the voltage swing of the data line (32) driving voltage between the positive and negative polarity gray scale is greatly reduced while the dot reversal driving is realized, thereby effectively reducing the power consumption of the array substrate (40) in the dot reversal driving mode.
