Step S112, exports the drive unit of parallax baffle to by the voltage across poles of described parallax baffle, thus controls corresponding region generation shading striped or printing opacity striped; The voltage across poles of described display panel is exported to the drive unit of display panel, thus control display panel display frame.
That is, the technical scheme that the present embodiment 1 provides is set the parameter of parallax baffle side, as long as display panel side normally display initial picture.
Concrete, to the setting of the voltage across poles of parallax baffle side in step S111, with reference to voltage distribution graph as shown in Figure 9, in first electrode 1202 of parallax baffle, the electrode voltage of electrode X2 and X3 in control 3D region is Vx, the voltage of electrode X1 and X4 in control 2D region is V1, in second electrode 1205 of parallax baffle, the voltage of electrode a2 and a3 of the photic zone in control 3D region is Va, the voltage of the electrode b2 of the shading region in control 3D region is Vb, and in the second electrode, the voltage of electrode a1, b1, b3 and the a4 in all the other regions is V2;

| Vb-Vx|≤Vth; Preferably, | Vb-Vx|=0;
|V1-V2|≈Vt,|V2-Vx|≈Vt,|V1-Va|≈Vt,|V1-Vb|≈Vt；
Wherein Vth is the threshold voltage that liquid crystal produces shading striped; Vsat is saturation voltage, and namely when being greater than threshold voltage, liquid crystal presents black state, completely light tight; Vt is the voltage required when Δ=0, and when Δ=0, the transmitance in the 3D region of parallax baffle is equal with the transmitance in 2D region.
So from above-mentioned relation:
For the shading region in 3D region, | Va-Vx|>Vth, or preferably, | Va-Vx|>Vsat, now liquid crystal is vertical, and the region corresponding to electrode a2 and a3 presents black state, realizes blocking completely;
For the photic zone in 3D region, | Vb-Vx|≤Vth, or preferably, | Vb-Vx|=0; Now, the region that electrode b2 is corresponding, namely the electric field intensity inside high of the photic zone in 3D region is 0, and liquid crystal does not deflect, and is shown as through state;
Thus for 3D region, the region display clear state that electrode b2 is corresponding, the region that electrode a2 and a3 is corresponding shows black state, and obtaining now overall transmitance is T

Step S122, exports the drive unit of parallax baffle to by the voltage across poles of described parallax baffle, thus controls corresponding region generation shading striped or printing opacity striped; The voltage across poles of described display panel is exported to the drive unit of display panel, thus control display panel display frame.
Concrete, to the setting of the voltage across poles of parallax baffle side in step S121, with reference to voltage distribution graph as shown in Figure 9, in first electrode 1202 of parallax baffle, the electrode voltage of electrode X2 and X3 in control 3D region is Vx, the voltage of electrode X1 and X4 in control 2D region is V1, in second electrode 1205 of parallax baffle, the voltage of electrode a2 and a3 of the photic zone in control 3D region is Va, the voltage of the electrode b2 of the shading region in control 3D region is Vb, and in the second electrode, the voltage of electrode a1, b1, b3 and the a4 in all the other regions is V2;
Above electrode voltage meets following relation:
| Va-Vx|>Vth; Preferably, | Va-Vx|>Vsat;
| Vb-Vx|≤Vth; Preferably, | Vb-Vx|=0;
|V1-V2|≦Vth,|V2-Vx|≦Vth,|V1-Va|≦Vth,|V1-Vb|≦Vth；
Wherein Vth is the threshold voltage that liquid crystal produces shading striped; Vsat is saturation voltage, and namely when being greater than threshold voltage, liquid crystal presents black state, completely light tight.
So from above-mentioned relation:
For the shading region in 3D region, | Va-Vx|>Vth, or preferably, | Va-Vx|>Vsat, now liquid crystal is vertical, and the region corresponding to electrode a2 and a3 presents black state, realizes blocking completely;
For the photic zone in 3D region, | Vb-Vx|≤Vth, or preferably, | Vb-Vx|=0; Now, the region that electrode b2 is corresponding, namely the electric field intensity inside high of the photic zone in 3D region is 0, and liquid crystal does not deflect, and is shown as through state;
Thus for 3D region, the region display clear state that electrode b2 is corresponding, the region that electrode a2 and a3 is corresponding shows black state, and obtaining now overall transmitance is T
