Traditional liquid crystal indicator shows image by using electric field controls liquid crystal molecule to rotate.As shown in Figure 1, traditional liquid crystal indicator generally includes: liquid crystal panel 100, is formed at a plurality of data lines 101 on liquid crystal panel 100, many gate lines 102, public electrode wire 103, gate line circuit 104, data line circuit 105 and public electrode wire output circuits 106.
Fig. 1 is the structural representation of a display panels in prior art.As shown in Figure 1, definition first direction is vertical direction, and definition second direction is horizontal direction.Described data line 101 extends in a first direction, and described gate line 102 extends in a second direction and intersects with described data line 101, and described public electrode wire 103 is parallel with described gate line 102 and intersect with described data line 101.Described a plurality of data lines 101 and gate line 102 form the pixel cell 110 of arrayed, are also configured with thin film transistor (TFT) (TFT) in each pixel cell 110.In addition, liquid crystal panel 100 is also equipped with memory capacitance C
sT, for maintenance medium crystal cell C
lCthe voltage of middle pixel electrode.One end of each gate line 102 described connects gate line circuit 104, and described gate line circuit 104 is for providing grid voltage to this gate line 102; Described data line 101 is connected with described data line circuit 105, and described data line circuit 105 is for providing data voltage to described data line 101; Described public electrode wire 103 is connected with described public electrode wire output circuit 106, and described public electrode wire output circuit 106 is for providing common electric voltage Vcom by described public electrode wire 103 to every row pixel cell 110.
After gate line circuit 104 provides a grid voltage to the grid of the TFT of corresponding line pixel cell 110 by gate line 102, corresponding TFT is opened, if at this moment data line 101 provide a driving voltage to pixel cell 110 and public electrode wire 103 provides a common electric voltage Vcom to pixel cell 110 time, then can change the arrangement of liquid crystal molecule thus control the transmittance of pixel cell 110; The TFT of remaining row pixel cell 110 is then in closed condition.
In order to keep the electric polarity of liquid crystal molecule, the type of drive for liquid crystal indicator is mainly divided into type of drive that common electric voltage Vcom is constant and the type of drive that common electric voltage Vcom overturns.Conventional type of drive is the type of drive that common electric voltage Vcom overturns, Fig. 2 is the sequential chart of common electric voltage in the display panels shown in Fig. 1, as shown in Figure 2, in order to keep the electric polarity of liquid crystal molecule, common electric voltage Vcom needs when often scanning one-row pixels unit 110, namely overturns once, then in each frame of scanning liquid crystal panel 100, common electric voltage Vcom will overturn many times, then common electric voltage Vcom discharge and recharge number of times is more, and the power consumption of liquid crystal indicator is higher.
