A pixel region is surrounded in any adjacent scan lines and any adjacent data lines. Two thin film transistor (TFT) groups that are controlled by different scan lines are located in each pixel region. The two data lines respectively send different polarity data to the pixel region through the two TFT groups. At least one capacitor is used to couple with the two TFT groups for providing a coupling effect to make sure the voltage in the two connection points simultaneously goes up and down.
