Array substrate, display device and driving method

A method of driving the array substrate, the array substrate comprising a plurality of gate lines extending in a first direction, a plurality of data lines extending in a second direction crossing the first direction, and a plurality of pixel units arranged as an array along the first direction and the second direction, wherein each of the plurality of data lines is arranged between two columns of the pixel units, the two columns of the pixel units extending in the second direction and being adjacent to each other in the first direction, and each of the plurality of data lines is connected to immediately adjacent pixel units;

• and wherein each of the plurality of data lines switches a connection direction from one side to the other in an alternating manner with each two adjacent rows of pixel units, and the plurality of data lines have the same connection direction in each row of pixel units,
• the method comprising:
• keeping the polarities of output signals on each data line unchanged within one frame, and making the polarities of output signals on two data lines adjacent in the first direction to be opposite, so that a voltage applied to the pixel units has a polarity inversion in the first direction using one pixel unit as a period and in the second direction using two pixel units as a period,
• wherein each pixel unit includes a first pixel electrode and a second pixel electrode, as well as a first thin film transistor and a second thin film transistor corresponding to the first pixel electrode and the second pixel electrode, respectively, the first pixel electrode and the second pixel electrode being respectively connected to respective drains of the first thin film transistor and the second thin film transistor,
• two gate lines corresponding to one row of pixel units are respectively connected to respective gates of the first thin film transistor and the second thin film transistor in said row of pixel units, connection relationship between gate lines and the first and the second thin film transistors being changed once every two rows of pixel units,
• the data lines are connected to the corresponding pixel units through respective sources of the first thin film transistor and the second thin film transistor.
