step S3, controlling the other grid wire of the two grid wires to be opened;
step S4, during the period of starting another grid wire, sequentially controlling the first Demux wire, the second Demux wire and the third Demux wire to be started; controlling the source wire to transmit signals to the pixel pairs connected with the data wires at the first position and the second position during the starting period of the first Demux wire; controlling the source wire to transmit signals to the pixel pairs connected with the data wires at the third position and the fourth position during the starting period of the second Demux wire; during the starting period of the third Demux trace, controlling the source trace to transmit signals to the pixel pairs connected with the data traces at the fifth position to the sixth position;
step S5, loop through steps S1-S4, drives each pixel cell.
