The invention discloses an array substrate, a drive method of the array substrate and a display device. The array substrate comprises a plurality of rows of pixel thin film transistors, at least one row of virtual pixel thin film transistors, a plurality of grid lines and a plurality of data lines. The multiple grid lines are connected with grid electrodes of the pixel thin film transistors and the virtual pixel thin film transistors in corresponding rows. The data lines are connected with source electrodes of the pixel thin film transistors and the virtual pixel thin film transistors in corresponding lines. The drain electrodes of the virtual pixel thin film transistors are connected with common electrodes so that preset voltage can be provided. The drain electrodes of the virtual pixel thin film transistors and the common electrodes are connected through via holes, during 3D displaying, data signals are pulled to the preset voltage, a black picture is displayed, and a black insertion function of a left eye image and a right eye image is achieved. During 2D displaying, the voltage of the data lines is pre-charged to the preset voltage after one frame picture is finished, the situation that the voltage of the data line is directly changed into a positive voltage value from a negative voltage value is avoided, and the flicking phenomenon of picture display is reduced.
