1). the vertical direction liquid crystal slit grating of compatible 2D and 3D demonstration simultaneously: shown in Fig. 4 a and Fig. 4 b, be the utility model part-structure synoptic diagram of compatible 2D and the vertical direction liquid crystal slit grating of 3D demonstration simultaneously, wherein 100 is second glass substrate of liquid crystal slit grating, and 200 is first glass substrate of liquid crystal slit grating.Wherein, 101 for being deposited on whole electro-conductive glass ITO(indium tin oxide on second glass substrate 100) or the IZO(indium-zinc oxide) etc., 201 for being produced on the strip electrode (ITO, IZO etc.) on first glass substrate, 200 surfaces, and 202 zones are non-electrode district.Among Fig. 4 b, the strip electrode 201 on first glass substrate 200 is divided into 6 zones, is respectively A, B, and C, D, E, F, each zone is separate, but all electrodes link together within each zone.
Fig. 5 has represented the situation that vertical direction liquid crystal slit grating 2D and 3D show simultaneously visually, because each zone is separate, voltage can separately be controlled.Suppose that second glass substrate 100 is a certain reference voltage, after all electrodes of the regional A of first glass substrate 200 apply another voltage and form certain pressure reduction, namely can chequered with black and white striped occur at regional A and (zone of electrode be arranged for black, electrodeless zone is white), so can realize that 3D shows at regional A; Meanwhile, when the voltage that applies in other area electrodes equaled reference voltage, other zones chequered with black and white striped can not occur owing to there is not pressure reduction, still presented 2D and showed, so 2D and 3D just are presented on the zones of different of same screen simultaneously.
At some in particular cases, need to realize that the zone that local 3D shows may be inconsistent with the isolated area that arranges.As shown in Figure 6, suppose to realize that for certain sub-picture the zone that 3D shows covers A and B zone fully, need apply then that a certain voltage forms first, second glass substrate 200,100 pressure reduction just can be realized in A, B zone.Suppose under certain situation, need the zone of 3D demonstration shown in P1 among Fig. 6, covered most of zone of A and B, can apply still then that a certain voltage forms first, second glass substrate 200,100 pressure reduction is realized in A, B zone, can sacrifice the zone that small part 2D shows this moment, because the area sum in A and B zone is greater than the area of P1, the zone that the P1 periphery on a small quantity should 2D shows has been shown by 3D.In contrast, suppose under certain situation, need the zone of 3D demonstration shown in P2 among Fig. 6, most of zone and the few part B zone of A have been covered, can only apply in the a-quadrant then that a certain voltage forms first, second glass substrate 200,100 pressure reduction is realized, can lose the information that small part 3D shows this moment, because the area of a-quadrant is less than the area of P2, the image of the former 3D that should show in few part B zone but present the 2D demonstration.Certainly, if the zone that slit grating is divided into is more many, the unit of independent control is also just more many, thisly in particular cases sacrifices a small amount of 3D or 2D shows that the situation of information will be more few.
2). the horizontal direction liquid crystal slit grating of compatible 2D and 3D demonstration simultaneously: as shown in Figure 7,200 is first glass substrate of liquid crystal slit grating.First glass substrate 200 is divided into 12 zones, is respectively A, B, and C, D ..., K, L.Each zone is separate, but all electrodes link together within each zone.
The expression of Fig. 8 image horizontal direction liquid crystal slit grating 2D and 3D situation about showing simultaneously because each zone is separate, voltage can separately be controlled.Suppose that second glass substrate 100 is a certain reference voltage, after all electrodes of the regional D of first glass substrate 200 apply another voltage and form certain pressure reduction, namely can chequered with black and white striped occur at regional D and (zone of electrode be arranged for black, electrodeless zone is white), so can realize that 3D shows at regional D; Meanwhile, when the voltage that applies in other area electrodes equaled reference voltage, other zones chequered with black and white striped can not occur owing to there is not pressure reduction, still presented 2D and showed, so 2D and 3D just are presented on the zones of different of same screen simultaneously.Accept or reject for type of drive in particular cases, can realize with reference to Fig. 6.
3). except above-mentioned realization level and vertical direction 2D and 3D show simultaneously, for reducing to crosstalk and balance aberration etc., also electrode can be tilted place according to certain angle.
In fact, the strip electrode 201 on first glass substrate 200 can be divided into the identical or different unit of several sizes, forms the matrix structure of the capable x N row of M.For amounting to M x N independently matrix, can be as required therein any a plurality of zone realize that 2D and 3D show simultaneously.
The preferred embodiment that the above is only created for the utility model; do not create in order to limit the utility model; all any modifications of within spirit that the utility model is created and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain that the utility model creates.
