Description
Technical field
The utility model relates to 3D stereo display technique field, in particular to 3D optical splitter and 3 d display device.
Background technology
In 3D stereo display technique, bore hole 3D, because just can watch the advantage in convenience and the application of 3D effect without other utility appliance, becomes the center of gravity of 3D display technique research.In various bore hole 3D display techniques, the auto-stereoscopic display device that adopts liquid crystal lens and liquid crystal slit grating is subject to extensive concern because of distinctive advantage separately.
The 3 d display device that adopts liquid crystal lens to realize, mainly to utilize, on two plate bases of liquid crystal layer both sides, positive and negative electrode is set respectively, and on Different electrodes, apply the driving voltage varying in size, thereby between two plate bases, form the vertical electric field with varying strength, form varifocal liquid crystal lens to drive Liquid Crystal Molecules Alignment.Therefore, the voltage that only need to control in respective electrode distributes, and the index distribution of liquid crystal lens will change accordingly, thereby the distribution of pixel emergent light is controlled, and realizes free stereo demonstration and 2D/3D and freely switches.
As Fig. 1 shows a kind of structural representation of common liquid crystal lens 3 d display device.As shown in Figure 1, existing liquid crystal lens 3 d display device 100 comprises two parts, and wherein Part I is conventional 2D display device 120, as LCD, OLED etc.; Part II is to be placed in 2D display device 120 liquid crystal lens array 110 before, and both generally paste by periphery or whole attaching process fits together formation auto-stereoscopic display device.Particularly, liquid crystal lens array 110 comprises multiple liquid crystal lens unit (as L1 and L2, only having drawn two lens units as example in figure), and each lens unit (as L1 and L2) has identical structure.Liquid crystal lens array 110 comprises first substrate 101 and second substrate 102, and first substrate 101 and second substrate 102 are just to arranging.On first substrate 101, be provided with the first electrode 103, on second substrate 102, be provided with the second electrode 107.Within each lens unit, taking L1 as example, the first electrode 103 comprise S11, S12, S13 ..., multiple strip electrodes that separate at certain intervals and be arranged in parallel such as S18, S19, the quantity of electrode is generally odd number (describing as an example of nine electrodes example below), the width of each strip electrode be respectively W (S11), W (S12), W (S13) ..., W (S18), W (S19) etc.Generally speaking, strip electrode possesses identical width, i.e. W (S11)=W (S12)=W (S13)=...=W (S18)=W (S19).Share same strip electrode S19 (S21) in joint, two liquid crystal lens unit (between L1 and L2).Further, liquid crystal lens array 110 also comprises the dielectric layer 104 being arranged on the first electrode 103; Be arranged on the second alignment film 108 on the second electrode 107 and be arranged on the first alignment film 105 on dielectric layer 104 for controlling the orientation of liquid crystal molecule, wherein the first alignment film 105 is parallel with the frictional direction of the second alignment film 108, and liquid crystal material 106 is encapsulated between first substrate 101 and second substrate 102.
As shown in Figure 1, in the time that needs carry out 2D demonstration, make liquid crystal lens array 110 in off working state, or make voltage difference between the first electrode 103 and the second electrode 107 be less than the threshold voltage of liquid crystal material 106, now the molecular orientation of liquid crystal material 106 is still initial orientation.(be △ ε=ε ∥-ε ⊥ >0 with positivity liquid crystal material, in formula, ε ∥ is the dielectric coefficient of long axis of liquid crystal molecule direction, ε ⊥ is the dielectric coefficient of liquid crystal molecule short-axis direction) be example, the major axis of all liquid crystal molecules is regularly arranged along the direction that is parallel to paper.From the light of 2D display panel outgoing, after impinging perpendicularly on liquid crystal layer 106, there is no optical path difference, also do not reflect, what therefore audience saw is still 2D picture, due to the high permeability of liquid crystal lens array 110, whole liquid crystal lens 3 d display device 100 still possesses the feature such as high brightness, high contrast, and the optical characteristics of former 2D display device 120 is substantially unaffected.
As shown in Figure 2, in the time that needs carry out 3D demonstration, at each strip electrode of the first electrode 103 of liquid crystal lens array 110 as S11, S12, S13, S18, on S19 (taking lens unit L1 as example) etc., apply symmetrical voltage, the second electrode 107 as public power extremely voltage be set to zero, taking positivity liquid crystal material as example, can make V (S11)=V (S19) >V (S12)=V (S18) >V (S13)=V (S17) >V (S14)=V (S16) >V (S15), the voltage minimum applying on the central electrode S15 of liquid crystal lens unit, and at the edge electrodes S11 of lens unit, the voltage maximum applying on S19, voltage from lens center to rims of the lens on each strip electrode distributes with certain gradient.Due to the voltage maximum applying on lens unit edge electrodes, the liquid crystal molecule corresponding with edge electrodes S11 and S19 position substantially presents vertical direction and distributes, and less the closer to the center voltage of lens unit, therefore liquid crystal molecule can tend to horizontal direction arrangement gradually.In each lens unit, because voltage symmetry distributes, liquid crystal material is along with the variation of electric field intensity presents the gradual change of refractive index, thereby whole liquid crystal lens array 110 forms multiple lenticules, to reflect light splitting from the light of 2D display device 120, the image of right and left eyes is projected to respectively to audience's left eye and right eye, thereby produces stereopsis.Taking four viewpoints in Fig. 2 as example, when distributing while being positioned at the position such as 1 and 2,2 and 3 and 3 and 4, audience's right and left eyes can see stereopsis.
For liquid crystal lens array 110, in each liquid crystal lens unit if each strip electrode in L1 is as S11, S12, S13 ..., S18, applies on S19 etc. after symmetrical voltage, arranges by voltage optimization, can obtain optical path difference in each lens unit and distribute.For crosstalking of reducing that liquid crystal lens causes in the time that 3D shows, avoid left (right side) eye image information to be perceived by right (left side) eye the quality that reduces stereo display respectively, need liquid crystal lens and the distribution of parabolic type lens light path difference to match.
As Fig. 3 has compared the difference that common liquid crystal lens optical path difference distributes and parabolic type lens light path difference distributes after optimizing.As can be seen from the figure, approach with desirable para-curve although liquid crystal lens unit optical path difference distribution curve after voltage optimization is basic in lens center, but two liquid crystal lens unit intersections (identifying with square frame in figure), liquid crystal lens optical path difference distributes and still obviously departs from desirable para-curve, use the 3 d display device generation of liquid crystal lens to crosstalk more greatly thereby cause, reduced stereo display effect and observed comfort level.

As shown in Figure 7, the voltage of the first common electrode 1007 is set to certain reference value Vref1, at the first electrode 1003 of each lens unit intersection (as 10031, 10032 and 10038, 10039 etc.) with the second electrode 1021 (as 10211 and 10218 etc.) on the voltage that applies equal Vref1, and at other first electrodes 1003 (as 10033, 10034, 10035, 10036 and 10037 etc.) with other second electrodes 1021 (as 10212, 10213, 10214, 10215, 10216 and 10217 etc.) on, apply certain identical driving voltage, this driving voltage is preferably the square wave of positive-negative polarity reversion, when positive-negative polarity reversion, relative the first common electrode 1007 has same pressure differential △ V1, the size of △ V1 should be enough to make the liquid crystal molecule optically-active characteristic of the first liquid crystal layer 1005 in this region to disappear, making long axis of liquid crystal molecule be parallel to z direction arranges.For the first liquid crystal layer 1005, liquid crystal molecule now produces two kinds of complete different orientations: the first at each lens unit intersection because the first electrode 1003 is (as 10031, 10032 and 10038, 10039 etc.) with the second electrode 1021 (as 10211 and 10218 etc.) on voltage equal the voltage Vref1 of the first common electrode 1007, between the liquid crystal molecule upper/lower electrode in this region, there is not pressure reduction, the initial orientation of liquid crystal molecule does not change, to produce optically-active effect from the linearly polarized light of 2D display device 1200 outgoing during by this region liquid crystal layer 1005, will be parallel with y direction of principal axis from the polarization direction of the linearly polarized light of liquid crystal layer 1005 outgoing, because the polarization direction of the first polaroid 1014 is x direction, therefore this region shows dark state.It two is on the non-marginal position of each liquid crystal lens unit, because the first electrode 1003 is (as 10033, 10034, 10035, 10036 and 10037 etc.) with the second electrode 1021 (as 10212, 10213, 10214, 10215, 10216 and 10217 etc.) on, apply certain identical driving voltage, the existence of pressure reduction △ V1 disappears the liquid crystal molecule optically-active characteristic of the first liquid crystal layer 1005, these region first liquid crystal layer 1005 long axis of liquid crystal molecule are arranged along z direction, from the linearly polarized light of 2D display device 1200 outgoing enters first liquid crystal layer 1005 in this region, the linearly polarized light polarization direction of incident does not change, be still the linearly polarized light parallel with x direction, because the polarization direction of the first polaroid 1014 is also x direction, therefore this region shows bright state.Therefore, under this voltage arranges, become light and dark striped from the light of the first polaroid 1014 outgoing, each lens unit intersection is narrower dark fringe, and is wider bright fringes at the non-intersection of each lens unit.
Meanwhile, the voltage of the second common electrode 1011 is set to certain reference voltage Vref 2, on third electrode 1009, apply a larger driving voltage, for the second liquid crystal layer 1013, form larger voltage difference in the second liquid crystal layer 1013 both sides, its molecular long axis of liquid crystal molecule on the strip electrode of each third electrode 1009 (in as figure five 10091 and 10095) will be parallel with direction of an electric field, arrange along z direction.In each lens unit, along with the strip electrode apart from third electrode 1009 (as 10091 and 10095), more electric field is more weak, and liquid crystal molecule tends to gradually horizontal direction and arranges.In each lens unit, due to the symmetrical distribution of voltage, the second liquid crystal layer 1013 is along with the variation of electric field intensity presents the gradual change of refractive index, form a lenticule unit, from the linearly polarized light parallel with x direction of the first polaroid 1014 outgoing enters the second liquid crystal layer 1013, will reflect to different angles.Because the light from the first polaroid 1014 outgoing is dark state at each lens unit intersection, therefore the liquid crystal slit being positioned under each lens unit intersection is closed, reduce crosstalking of lens unit intersection.According to actual needs, can adjust that in the first electrode 1003 and the second electrode 1021, to apply reference voltage Vref 1 number of electrodes how many, reach best appreciation effect with crosstalk reduction.
