As shown in Figure 9, Fig. 9 is a kind of schematic block diagram that uses the 2D/3D display switching device of this driver module.This 2D/3D display switching device comprises M the first electrode 11 with N the second electrode 12, the first electrode 11 and the second electrode 12 intervals and is oppositely arranged.Between the first electrode 11 and the second electrode 12, be provided with liquid crystal layer (not shown).The first Voltage-output module 13 is respectively each first electrode 11 the first driving voltage is provided, and second voltage output module 14 is respectively each second electrode 12 the second driving voltage is provided.The first electrode 11 and the second electrode 12 are strip electrode arranged in a crossed manner, yet in other application, the first electrode 11 and the second electrode 12 can adopt drive electrode and public electrode.The effect of the first electrode 11 and the second electrode 12 is by the liquid crystal molecule of liquid crystal layer is applied to different electric fields, makes liquid crystal molecule in different deflection angles, and then realizes 2D or 3D display effect.
The first Voltage-output module 13 further receives the first voltage adjustment signal, and according to the first driving voltage of the first voltage adjustment signal adjustment output.In addition, second voltage output module 14 further receives second voltage and adjusts signal, and according to second voltage, adjusts the second driving voltage of signal adjustment output.
Can produce according to different situations the first voltage adjustment signal and/or second voltage and adjust signal, adjust the first driving voltage and/or the second driving voltage.
Can according to the first Voltage-output module 13 or second voltage output module 14 the first driving voltages of output or the off-set value of the second driving voltage relative standard voltage generates the first voltage adjustment signal or second voltage is adjusted signal.For example, when the first Voltage-output module 13 or second voltage output module 14 the first driving voltages of output or the magnitude of voltage of the second driving voltage being detected because of design error or other reasons generation skew, and the off-set value of its relative standard's voltage has surpassed the scope allowing, thereby may cause switching time by mistake, according to this off-set value, producing the first voltage adjustment signal or second voltage adjusts signal and adjusts the first Voltage-output module 13 or second voltage output module 14, to change the first driving voltage of its output or the magnitude of voltage of the second driving voltage, voltage difference between the first electrode and the second electrode is remained in rational scope.
In addition, also can switch the shown 3D displaying contents of stereoscopic display device according to 2D/3D and produce the first voltage adjustment signal and second voltage adjustment signal.For different 3D displaying contents, its needed 3D display effect is also not quite similar.Therefore, according to different 3D displaying contents, producing the first different voltage adjustment signals or second voltage adjusts signal and changes the voltage difference between the first electrode and the second electrode, and then realize the dynamic adjustment of the deflection angle of the liquid crystal molecule in 2D/3D display switching device, produce the power contrast of stereoeffect, and can improve sharpness and the visual granular sensation of 3D picture.
Further, can produce the first voltage adjustment signal and second voltage adjustment signal according to 3D viewing area positional information, and then according to user, need to change the position of 3D viewing area.
The first Voltage-output module 13 and second voltage output module 14 show to switch according to 2D/3D need to export different magnitudes of voltage.For example, in the situation that whole picture only shows 2D picture, the first Voltage-output module 13 to each first electrode 11 output amplitude at the first magnitude of voltage (for example, 1.6V) with second voltage value (for example, the first driving voltage of pulse change 2.8V), second voltage output module 14 to each second electrode 12 output amplitude at the first magnitude of voltage (for example simultaneously, 1.6V) with second voltage value (for example, the second driving voltage of pulse change 2.8V), and the first driving voltage and the second driving voltage inverting each other.That is to say, when the first driving voltage is 1.6V, the second driving voltage is 2.8V, when the first driving voltage is 2.8V, the second driving voltage is 1.6V, guarantees thus whole the first electrodes 11 that whole picture is corresponding and the remain at ± 1.2V of voltage difference between the second electrode 12.Now, the liquid crystal molecule in 2D/3D display switching device is all in the first deflection angle, and then whole picture can be used for only showing 2D picture.
In the situation that whole picture only shows 3D picture, the first Voltage-output module 13 to each first electrode 11 output amplitude in tertiary voltage value (for example, 0.4V) with the 4th magnitude of voltage (for example, the first driving voltage of pulse change 4.0V), second voltage output module 14 to each second electrode 12 output amplitude in tertiary voltage value (for example simultaneously, 0.4V) with the 4th magnitude of voltage (for example, the second driving voltage of pulse change 4.0V), and the first driving voltage and the second driving voltage inverting each other.That is to say, when the first driving voltage is 0.4V, the second driving voltage is 4.0V, when the first driving voltage is 4.0V, the second driving voltage is 0.4V, guarantees thus whole the first electrodes 11 that whole picture is corresponding and the remain at ± 3.6V of voltage difference between whole the second electrode 12.Now, the liquid crystal molecule in 2D/3D display switching device is all in the second deflection angle, and then whole picture can be used for only showing 3D picture.
As shown in figure 10, when needs show 2D and 3D picture simultaneously, according to 3D viewing area positional information, determine and show the 3D viewing area 29 of 2D picture and the 2D viewing area 21-28 that shows 2D picture, determine the first electrode 11 and the second electrode 12 in corresponding 3D viewing area 29 simultaneously, and then generate the first corresponding voltage adjustment signal and second voltage adjustment signal.
For example, 3D viewing area positional information can be the coordinate figure (or, can also be the coordinate figure at 29 edges, 3D viewing area) in four corners of 3D viewing area 29.Now, a to the b the first electrode 11 in M the first electrode 11 is in 3D viewing area 29, and c to the d the second electrode 12 in N the second electrode 12 is in 3D viewing area 29 simultaneously.
The first Voltage-output module 13 according to the first voltage adjustment signal to a to b in 3D viewing area 29 the first electrode 11 output amplitudes in tertiary voltage value (for example, 0.4V) with the 4th magnitude of voltage (for example, the first driving voltage of pulse change 4V), first electrode 11(1st to a-1 first electrode 11 and b+1 to the M first electrode 11 of while outside 3D viewing area 29) output at the first magnitude of voltage (for example, 1.6V) with second voltage value (for example, 2.8V) between the first driving voltage of pulse change.
Second voltage output module 14 to c to the d in 3D viewing area 29 the second electrode 12 output amplitudes in tertiary voltage value (is for example adjusted signal according to second voltage value, 0.4V) with the 4th magnitude of voltage (for example, the second driving voltage of pulse change 4V), second electrode 12(1st to c-1 second electrode 12 and d+1 to the N second electrode 12 of while outside 3D viewing area 29) output at the first magnitude of voltage (for example, 1.6V) with second voltage value (for example, 2.8V) between the second driving voltage of pulse change.
Now, on the first electrode 11 outside control 3D viewing area 29 and the second electrode 12, the first driving voltage and the second driving voltage are inverting each other, therefore the first electrode 11 outside 3D viewing area 29 and the still remain on ± 1.2V of voltage difference between the second electrode 12.That is to say the first electrode 11 in 2D viewing area 21,23,25,27 and the remain on ± 1.2V of voltage difference between the second electrode 12.
Control the first electrode 11(a to the b the first electrode 11 in 3D viewing area 29) on the first driving voltage and 3D viewing area 29 outside the 1st to c-1 the second electrode 12 of the second electrode 12(and d+1 to the N the second electrode 12) on the second driving voltage homophase, simultaneously the second electrode 12(c to the d the second electrode 12 in 3D viewing area 29 each other) on the second driving voltage and 3D viewing area 29 outside individual the first electrode 11 of the first electrode 11(the 1st to a-1 and individual the first electrode 11 of b+1 to the M) on the first driving voltage homophase each other.That is to say, when the first driving voltage is 0.4V, the second driving voltage is 1.6V, when the first driving voltage is 4V, the second driving voltage is 2.8V, guarantees thus the first electrode 11 or the second electrode 12 outside the second electrode 12 and 3D viewing area 29 or the also remain ± 1.2V of voltage difference between the first electrode 11 in 3D viewing area 29.That is to say the first electrode 11 in 2D viewing area 22,23,24,28 and the remain on ± 1.2V of voltage difference between the second electrode 12.
Meanwhile, the first driving voltage the first electrode 11 of the first electrode 11(a to the b in 3D viewing area 29) and the second electrode 12(c to the d in 3D viewing area 29 the second electrode 12) on the second driving voltage inverting each other.Namely, when the first driving voltage is 4V, the second driving voltage is 0.4V, and when the first driving voltage is 0.4V, the second driving voltage is 4V, guarantees thus the first electrode 11 in 3D viewing area 29 and the remain ± 3.6V of voltage difference between the second electrode 12.
In this way, can be so that the liquid crystal molecule in the 2D viewing area 21-28 in 2D/3D display switching device all under the voltage difference in ± 1.2V, so that in the first deflection angle, example direction as shown in Figure 2, and then can be used for only showing 2D picture.Meanwhile, the liquid crystal molecule in the 3D viewing area 29 in 2D/3D display switching device is all under the voltage difference in ± 3.6V, so in the second deflection angle, example direction as shown in Figure 1, and then can be used for showing 3D picture.
If user changes the position of 3D viewing area 29 in Figure 10, for example, toward moving to left, still can use said method, 3D viewing area and 2D viewing area are changed, still can show well 3D picture and 2D picture.
If user changes the size of 3D viewing area 29 in Figure 10, for example dwindle or expand 3D viewing area 29, still can use said method, 3D viewing area and 2D viewing area are changed, still can show well 3D picture and 2D picture.
By the way, according to user's needs, change the position of 3D viewing area, solved crosstalking between 2D viewing area and 3D viewing area simultaneously.
In addition, as shown in Figure 8, voltage adjustment signal can directly be inputted by control port 19, also can be produced by processing module 20.When being produced by processing module 20,3D viewing area positional information, 3D displaying contents or variation value are input to processing module 20 through control port 19, then produce corresponding voltage adjustment signal by the predetermined processing logic of processing module 20 execution.
More than explanation is just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skills understand, in the situation that do not depart from the spirit and scope that claims limit; can make many modifications, variation or equivalence, but all will fall within the scope of protection of the present invention.
