The shaded rectangle in FIG. 1 is a pixel electrode 9. A switch 10 and the pixel electrode 9 are provided at the intersections of the data lines S1˜Sn and the scanning lines G1˜Gn. The switch 10 is used to connect with the pixel electrode 9, the data lines S1˜Sn, and the scanning lines G1˜Gn. The working principle thereof is that the driving IC 8 outputs the pixel voltage and the control signal to the data lines S1˜Sn and the scanning lines G1˜Gn, the scanning lines G1˜Gn receives the control signal output from the driving IC 8 to control the switch 10 to turn on or off, the data lines S1˜Sn receive the pixel voltage and charge to the corresponding pixel electrode 9.
