Along with the continuous maturation of lcd technology, market is developed towards directions such as high-contrast, high brightness, low colour cast, wide angle of visibilities for the performance requirement of liquid crystal indicator. The technology being capable of wide angle of visibility requirement at present mainly has three kinds: Twisted Nematic liquid crystal (TwistNematic, TN) liquid crystal indicator of wide viewing-angle film, copline switch mode (InPlaneSwitch are mixed, IPS) liquid crystal indicator, multi-domain vertical alignment (Multi-domainVerticalAlignment, MVA) liquid crystal indicator. Wherein, MVA liquid crystal indicator, by the orientation of liquid crystal molecule is split, forms double; two farmland, four points of farmlands and eight points of domain modes, thus improving viewing angle characteristic.

Example, as shown in Figure 1 and Figure 2, grid line 1 and data wire 2 intersection limit subpixel regions to the structure of a subpixel regions in existing pair of farmland display floater 100, and subpixel regions includes thin film transistor (TFT) 3, pixel electrode 11 and public electrode 21. Wherein, public electrode 21 is formed on the second substrate 23 of second substrate 20 and has multiple second projection 22 on public electrode 21; Pixel electrode 11 is formed on the first substrate 13 of first substrate 10 and has multiple first projection 12 on pixel electrode 11.

When public electrode 21 and pixel electrode 11 no applied voltage, long axis of liquid crystal molecule is perpendicular to first substrate 10 and second substrate 20, but as in figure 2 it is shown, the liquid crystal molecule near the first protruding 12 and second projection 22 can present the heeling condition of correspondence along with the surface of the first protruding 12 and second projection 22. After public electrode 21 and pixel electrode 11 apply relevant voltage, liquid crystal molecule deflects under the effect of electric field, forms multidomain structure.

The liquid crystal molecule liquid crystal molecule difference in the first projection or the both sides of the second projection a and b as shown in Figure 3, then in the display floater of double; two farmlands, the display effect that user sees in different angles is essentially identical, and display floater has bigger visual angle.

If Fig. 4 is existing a kind of four points of farmland display floaters 100, it is by the convex design of two shown in Fig. 1 point farmland display floater into a bent shape, so that the initial tilt angle of liquid crystal doubles, forms four points of farmlands.

As shown in Figure 5, structure for a subpixel regions in a kind of eight points of farmland display floaters 100, one subpixel regions includes the first sub-sub-pix 101 and the second sub-sub-pix 102 varied in size, first sub-sub-pix and the second sub-sub-pix have certain voltage difference, every sub-sub-pix forms four points of farmlands, and two sub-sub-pixs form eight points of farmlands.

Embodiments provide the driving method of a kind of display device, including:

Step 201, to grid line export scanning gate signal.

Step 202, to data wire outputting data signals.

Step 203, export the first voltage signal to the first public electrode.

Step 204, export the second voltage signal to the second public electrode; Wherein, the voltage swing of the first voltage signal and the second voltage signal is different.

Simultaneously driving it should be noted that above-mentioned steps 201-step 204 is preferably when driving, grid line and data wire export signal respectively and so that the thin film transistor (TFT) of each subpixel regions of correspondence is opened, and then can charge to pixel electrode.Simultaneously, different voltage signals is loaded with step 204 to the first public electrode and the second public electrode by step 203, then the first public electrode and pixel electrode form the first electric field, second public electrode and pixel electrode form the second electric field, the intensity of the first electric field and the second electric field is different, thus the liquid crystal deflection angle being positioned at the first electric field and the second electric field is different, it is achieved a point farmland number for a subpixel regions is doubled, and then the visual angle of the display floater increased.

The above; being only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope that the invention discloses; change can be readily occurred in or replace, all should be encompassed within protection scope of the present invention. Therefore, protection scope of the present invention should be as the criterion with described scope of the claims.
