ARRAY SUBSTRATE, DISPLAY DEVICE, AND METHOD FOR DRIVING ARRAY SUBSTRATE

摘要

An array substrate, a display device, and a method for driving the array substrate not only can implement polarity inversion but also can effectively reduce a driving voltage of a pixel electrode and a common electrode, achieving the objective of reducing power consumption. The array substrate comprises: several pixel units (14); several grid lines (11) providing a grid scanning signal for the pixel units (14); several data lines (12) providing a data signal for the pixel units (14); and several first common electrode lines (131) and several second common electrode lines (132), each first common electrode line (131) being connected to an odd-numbered columns of pixel units (141) and each second common electrode lines (132) being connected to an even-numbered columns of pixel units (142). Common voltages with inverse polarities are respectively provided for the odd-numbered columns of pixel units (141) and the even-numbered columns of pixel units (142). A polarity of a driving voltage difference loaded to any pixel unit (14) through the data line (12) and the first common electrode line (131)/the second common electrode line (132) is inverse to a polarity of a common voltage loaded to the pixel unit (14).
