Step S112 exports the voltage across poles of described parallax baffle to the drive unit of parallax baffle, produces shading striped or printing opacity striped thereby control corresponding zone; The voltage across poles of described display panel is exported to the drive unit of display panel, thus control display Display panel picture.
That is to say, the technical scheme that the present embodiment 1 provides is for to set the parameter of parallax baffle side, and as long as display panel side is the normal initial picture that shows.
Concrete, in step S111 to the setting of the voltage across poles of parallax baffle side, with reference to voltage distribution plan as shown in Figure 9, in the first electrode 1202 of parallax baffle, the electrode X2 in control 3D zone and the electrode voltage of X3 are Vx, the electrode X1 in control 2D zone and the voltage of X4 are V1, in the second electrode 1205 of parallax baffle, the electrode a2 of the photic zone in control 3D zone and the voltage of a3 are Va, the voltage of the electrode b2 of the shading region in control 3D zone is Vb, and the voltage of all the other regional electrode a1, b1, b3 and a4 is V2 in the second electrode;
Above electrode voltage satisfies following relation:
| Va-Vx|〉Vth; Preferably, | Va-Vx|〉Vsat;
| 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 the shading striped; Vsat is saturation voltage, and namely when greater than threshold voltage, liquid crystal presents black attitude, and is fully light tight; Vt is needed voltage when the Δ=0, and when Δ=0, the transmitance in the 3D zone of parallax baffle equates with the transmitance in 2D zone.
So by above-mentioned relation as can be known:
For the shading region in 3D zone, | Va-Vx|〉Vth, perhaps preferably, | Va-Vx|〉Vsat, this moment, liquid crystal was vertical, and the corresponding zone of electrode a2 and a3 presents black attitude, realizes blocking fully;

| 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 the shading striped; Vsat is saturation voltage, and namely when greater than threshold voltage, liquid crystal presents black attitude, and is fully light tight.
So by above-mentioned relation as can be known:
For the shading region in 3D zone, | Va-Vx|〉Vth, perhaps preferably, | Va-Vx|〉Vsat, this moment, liquid crystal was vertical, and the corresponding zone of electrode a2 and a3 presents black attitude, realizes blocking fully;
For the photic zone in 3D zone, | Vb-Vx|＜=Vth, perhaps preferably, | Vb-Vx|=0; At this moment, the zone that electrode b2 is corresponding, namely the internal electric field intensity of the photic zone in 3D zone is 0, not deflection of liquid crystal is shown as through state;
Thereby for 3D zone, the zone that electrode b2 the is corresponding attitude that shows transparency, the zone that electrode a2 and a3 are corresponding shows black attitude, obtaining this moment whole transmitance is T
