Fig. 3 is in correlation technique, founds the schematic diagram of the 3 d display device 2D display device of technology based on liquid crystal lens pillar film.From structure, this liquid crystal lens pillar film 3 d display device 100 comprises three parts generally, and namely 2D shows module layer 110, rotatory device layer 120 and liquid crystal lens pillar film 130.Wherein, it can be common TFT-LCQ and thin-film transistor LCD device that 2D shows module layer 110, repeats no more here.Rotatory device layer 120 mainly comprises just to the first substrate 121 arranged and second substrate 122, be formed at the first electrode 123 of first substrate 121 side, the second electrode 124 being formed at second substrate 122 side and the liquid crystal layer 125 be sealed between first substrate 121 and second substrate 122.First electrode 123 and the second electrode 124 are provided with horizontal alignment film near the side of liquid crystal layer 125, and its frictional direction is mutually orthogonal, 90 degree of angles.Liquid crystal lens pillar film 130 mainly comprises three parts, i.e. flexible base plate 131, be formed at the some concavees lens unit 132 on flexible base plate 131, and the liquid crystal layer 133 be filled among concavees lens unit 132, here flexible base plate 131 is generally resistant to elevated temperatures PET, concavees lens unit 132 carries out extruding also ultra-violet curing by Optical transparent adhesive at mould or tool surface to take shape in the surface of flexible base plate 131, (in figure, small circle represents that the molecular long axis normal of liquid crystal layer 133 is in paper to liquid crystal layer 133, namely liquid crystal molecule molecular long axis is parallel to Y-direction) be generally ultraviolet curable positivity liquid crystal material, solid state powder is generally under normal temperature, the formation process of liquid crystal layer 133 mainly comprises friction, molten state liquid crystal aligning and ultra-violet curing.Liquid crystal lens pillar film 130 and rotatory device layer 120 generally carry out face subsides by Optical transparent adhesive or liquid optical cement, and rotatory device layer 120 and 2D show between module layer 110 and generally carry out face subsides by liquid optical cement.
(X in three Cartesian coordinates, Y, Z) in, if the polarized light polarization direction showing polaroid outgoing module layer 110 from 2D is aa ', aa ' is parallel to Y-axis, when rotatory device layer 120 be in be not energized namely OFF state time, ideally after 90 degree of optically-actives, be bb ' direction from the line polarisation polarization direction 90-degree rotation of rotatory device layer 120 outgoing, bb ' is parallel to X-axis.If the friction orientation direction that rr ' (being parallel to Y-axis) is liquid crystal layer 133, for liquid crystal layer 133, because the polarization direction bb ' of incident light is vertical with long axis of liquid crystal molecule direction, now refractive index is no (no is liquid crystal molecule 133 short-axis direction refractive index), when forming the refractive index n=no of Optical transparent adhesive of concavees lens unit 132, then do not reflect at the interface of liquid crystal layer 133 with concavees lens unit 132, namely incident light rectilinear propagation can show 2D.
As shown in Figure 4, if the polarized light polarization direction showing polaroid outgoing module layer 110 from 2D is aa ', namely Y-axis is parallel to, when rotatory device layer 120 is in energising and ON state, ideally its optically-active characteristic disappears, be parallel to aa ' from the line polarisation polarization direction bb ' of rotatory device layer 120 outgoing, be namely parallel to Y-axis.If the friction orientation direction that rr ' (being parallel to Y-axis) is liquid crystal layer 133, for liquid crystal layer 133, because the polarization direction bb ' of incident light is parallel with long axis of liquid crystal molecule direction, now refractive index is that (ne is liquid crystal molecule 133 long axis direction refractive index to ne, owing to being positivity liquid crystal material, therefore ne>no), and form the refractive index n=no<ne of the Optical transparent adhesive of concavees lens unit 132, then reflect at the interface of liquid crystal layer 133 with concavees lens unit 132, namely incident light can show 3D because reflecting convergence.During 3D display, if the first electrode 123 of rotatory device layer 120 and the second electrode 124 are all face electrodes, show overall 3D, if when the first electrode 123 of rotatory device layer 120 and the second electrode 124 wherein have at least an electrode to have a special graph, local 3D display can be realized.
As the description in above, liquid crystal lens pillar film 3 d display device 100 realizes 3D display by the form of pad pasting (130) outward at liquid crystal cell (including rotatory device layer 120 and 2D display module layer 110), in addition also have a kind of so-called incell3D technology, core devices such as the lens arrangement being about to realize 3D is arranged on liquid crystal cell inside.Be that a kind of existing liquid crystal post lens 3 d display device 2D shows schematic diagram as shown in Figure 5, this liquid crystal post lens 3 d display device 200 comprises three parts generally, i.e. backlight 210,2D display panel 220 and liquid crystal post lens 230.Wherein, 2D display panel 220 mainly comprises (colored filter) glass substrate 224, under (array) glass substrate 223, be attached at the upper polaroid 222 on top glass substrate 224 surface, the lower polaroid 221 being attached at lower glass substrate 223 surface and the liquid crystal layer (not shown) be sealed between upper and lower glass substrate 224 and 223.Liquid crystal post lens 230 comprise infrabasal plate 231 and just to arrange upper substrate 232, infrabasal plate 231 and upper substrate 232 can be glass or other transparent materials, the first electrode 237 is provided with on upper substrate 232, the transparent material 235 (being generally optical resin) that refractive index is n is provided with on the first electrode 237, transparent material 235 just to the side of infrabasal plate 231 formed periodic groove structure (as, concavees lens), 236 is each periodic grooves structure spacing in the X direction, it is level and smooth convex lens curved surface that the groove structure that transparent material 235 is formed should make by the upper space formed between transparent material 235 and infrabasal plate 231.Liquid crystal layer 233 is filled between upper substrate 232 and infrabasal plate 231, because transparent material 235 has periodic groove structure, the liquid crystal layer 233 be therefore filled between upper substrate 232 and infrabasal plate 231 has convex lens curved surface in the side near transparent material 235.Infrabasal plate 231 just the side of upper substrate 232 is being provided with the second electrode 238, first electrode 237 and the second electrode 238 can be formed by ITO and indium tin oxide etc.Liquid crystal layer 233 can be negative liquid crystal (i.e. dielectric anisotropy △ ε=ε ∥-ε ⊥ <0, in formula, ε ∥ is the dielectric coefficient in long axis of liquid crystal molecule direction, ε ⊥ is the dielectric coefficient of liquid crystal molecule short-axis direction), also can be positivity liquid crystal, here for positivity liquid crystal.
As shown in Figure 5, (X in three Cartesian coordinates, Y, Z) in, when carrying out 2D display, only need apply certain driving voltage between the first electrode 237 and the second electrode 238, the size of this driving voltage should be enough to the initial orientation changing liquid crystal molecule in liquid crystal layer 233, thus makes the major axis of the liquid crystal molecule in liquid crystal layer 233 (being also direction of an electric field) homeotropic alignment along the Z direction.Now, from 2D display panel 220, the polarized light of the Y-direction of polaroid 222 outgoing is no by refractive index during liquid crystal layer 233, due to the refractive index n=no of transparent material 235, therefore do not reflect at the interface of liquid crystal layer 233 with transparent material 235, can 2D display be carried out.
Then without the need to driving liquid crystal post lens 230 during 3D display, liquid crystal molecule in liquid crystal layer 233 is still Y-direction orientation, i.e. natural orientation (small circle in Fig. 6 in liquid crystal layer 233 represents that the long axis of liquid crystal molecule of liquid crystal layer 233 is perpendicular to paper, and namely molecular long axis is parallel to Y-direction).From the line polarisation bb ' of the Y-direction polarization of 2D display panel 220 outgoing by liquid crystal layer 233 time, because polarization direction is parallel with the long axis of liquid crystal molecule direction of liquid crystal layer 233, its refractive index is ne, because of the refractive index n=no<ne of transparent material 235, therefore reflect at the interface of liquid crystal layer 233 with transparent material 235, light collection can carry out 3D display.
Above-mentioned two kinds of 2D/3D compatible techniques, be that pad pasting realizes 3D display or incell3D relates to the friction process of post lens coating or substrate (being respectively formed at flexible diaphragm if PET or rigid substrate are as glass surface by post lens microstructure), incell3D technology also related to PI and the sub-alignment films coating process of polyamides of post lens substrate.As shown in Figure 1, the concavees lens array of structures 235 formed by materials such as Optical transparent adhesive is arranged at substrate 232 surface, because the sagitta h of concavees lens unit is larger, general about about 20um or more, make high some A in concavees lens unit, pole low spot B 2 has larger vertical short difference, can not by method printing PI (planographic) of APR impact transfer printing as TFT_LCQ, existing scheme adopts the form syringe needle 10 of inkjet printing that PI liquid 11 is sprayed at concavees lens body structure surface, simultaneously for preventing from PI liquid from flowing causing B dot thickness large and A dot thickness is little, form coating PI (thick black line represents) adopting sprinkling limit, limit to be heating and curing is in concavees lens cell surface.
Post lens arrangement array is when carrying out friction orientation, as shown in Figure 2,20 is friction rollers, and 21 is double faced adhesive tapes, for fixed friction cloth 22 at roller 20 circumferentially, when friction roller 20 and concavees lens array of structures move in a circle by direction as shown respectively and rectilinear motion time can complete friction.During friction, because high some A of concave mirror arrangements 235 and pole low spot B vertical section difference h is larger, the intensity that concavees lens curved inner surface ABC is rubbed everywhere is different, the vertical range comparatively friction intensity being positioned at the PI alignment films distance friction cloth 22 of A point is larger, and the larger frictional strength of vertical range being positioned at the PI alignment films distance friction cloth 22 of B point is less, the difference of PI alignment film rubbing intensity causes diverse location liquid crystal aligning degree varies to cause, and when finally causing 3D to show, crosstalk increases.
In view of this, this application provides bore hole 3D display device, as shown in Figure 18 and Figure 19, comprising:
Liquid crystal lens pillar layer;
Described liquid crystal lens pillar layer comprises the Fresnel Lenses unit 1301 of multiple column, and multiple described Fresnel Lenses unit 1301 be arranged in parallel;
Described Fresnel Lenses unit 1301 comprises rectangular sheet base plate 1305, the first projection 1302 of column and the second projection 1303 of column, described first projection 1302 and described second projection 1303 are all arranged on the side surface of described base plate 1305 towards beam projecting, described first protruding 1302 and described second protruding 1303 all be arranged in parallel along the length direction of described base plate 1305, and the primary optical axis 1306 of the primary optical axis 1306 of described first projection 1302 and described second projection 1303 overlaps.
In fact, four parts are included in Fresnel Lenses unit 1301, the first projection 1302 respectively, second projection 1303, 3rd projection 1304 and base plate 1305, first projection 1302, second protruding 1303 and second projection 1303 is arranged on the same side of base plate 1305, first protruding 1302 and second protruding 1303 equal indentations, the shape of 3rd projection 1304 in convex lens, the sagitta h ' (as shown in Figure 7) of each projection is maximum is no more than 20um, preferable range is between 5 ~ 15um, the sawtooth quantity formed in each Fresnel Lenses unit is no more than 6 (namely the quantity of the first protruding 1302 and second projection 1303 is all 3), be preferably 2 and (namely only have one first protruding 1302 and second projection 1303, in Fig. 7, sawtooth is 4).
Wherein, as shown in figure 19, the state that multiple described Fresnel Lenses unit be arranged in parallel is illustrated.Concrete, all first protruding 1302 and second projection 1303 be all be arranged in parallel (in other words, the short transverse of all formation first projections 1302 edge and all second projections 1303 the edge of short transverse be all parallel).
Below, the formation basic theory of Fresnel Lenses unit is first introduced.With reference to one, the top figure of Fig. 7, it is the plano-convex lens structure (specifically referring to be filled with the dash area of array spot) that existing 3 d display device realizes 3D display employing, the sagitta that these convex lens have is h (marking in left side), when the light being parallel to convex lens principal-axis incident penetrates from convex lens curved surface, due to from optically denser medium to the difference of optically thinner medium refractive index, its focus O will be converged according to refraction principle.Because light only reflects at curved surface place, with reference to the view being positioned at middle part in Fig. 7, the part (grey fill area) not changing light transmition direction is removed, the curvature portion of reservation convex lens, and by remaining part translation to lens, just the view as Fig. 7 bottom can be obtained, i.e. Fresnel Lenses.Because Fresnel Lenses is identical with former convex lens radius-of-curvature everywhere, same refraction law of observing pools picture to incident light.Simultaneously, owing to having carried out the translation of lens curved surface part, the Fresnel Lenses focal length formed shortens, and (former concave lens focus is O, the Fresnel Lenses focus formed is O ', namely focus moves to O ' point from O), make that 3 d display device viewing distance is corresponding to be reduced, be therefore more suitable for using in small-medium size individual consumer's goods field.While formation Fresnel Lenses, because eliminating the part material not changing light transmition direction in convex lens, Fresnel Lenses is made to have less sagitta h '.As can be seen from Figure 7, the sagitta of former convex lens is h, and the Fresnel Lenses sagitta h ' formed can meet h ' h/2.
It should be noted that, Tu18Zhong, the said first protruding 1302 and second projection 1303 all refers to mutually corresponding projection.As in Figure 18, first first, left side protruding 1302 and first, right side the second projection 1303 are mutually corresponding, and second first, left side protruding 1302 and second, right side the second projection 1303 are mutually corresponding.Can be that the first projection 1302 of correspondence mutually and the primary optical axis 1306 of the second projection 1303 overlap, also can be that the primary optical axis 1306 of each first protruding 1302 and second projection 1303 all overlaps.In fact, primary optical axis 1306 is set of the focus of the focus of the first projection 1302, the focus of the second projection 1303 and the 3rd projection 1304, and only these three protruding focuses overlap completely, thus define primary optical axis 1306.
Below, with four concrete examples, the bore hole 3D display device that the application provides also is described respectively.
Example 1:
As shown in Figure 8,1000 be bore hole 3D display device first embodiment that the application provides 2D show schematic diagram.From structure, this bore hole 3D display device 1000 comprises three parts generally, and namely 2D shows module layer 110, rotatory device layer 120 and liquid crystal lens pillar layer 1300.Wherein, 2D shows the 3 d display device (Fig. 3 in the structure of module layer 110 and rotatory device layer 120 and correlation technique, Fig. 4) substantially identical, for rotatory device layer 120, first substrate 121 and second substrate 122 can be glass or other transparent soft materials, first electrode layer 123 and the second electrode lay 124 can be ITO electro-conductive glass (indium tin oxides), 3rd liquid crystal layer 125 generally selects positivity liquid crystal material, i.e. dielectric anisotropy △ ε=ε ∥-ε ⊥ >0, in formula, ε ∥ is the dielectric coefficient in long axis of liquid crystal molecule direction, ε ⊥ is the dielectric coefficient of liquid crystal molecule short-axis direction, 3rd liquid crystal layer 125 is common twisted nematic (twistnematic) liquid crystal, be rendered as liquid crystal state at normal temperatures.And liquid crystal lens pillar layer 1300 uses Fresnel lens structure, specifically, at first flexible base plate 1311 (the first flexible base plate, as PET) surface be provided with transparent optical glue-line 1321 (the first transparent optical glue-line), form the curved-surface structure needed for Fresnel Lenses at transparent optical glue-line 1321 (the first transparent optical glue-line) away from the side of flexible base plate 1311, filled by liquid crystal layer 1331 and form Fresnel Lenses.Flexible base plate 1311, away from the side of Optical transparent adhesive 1321, needs to carry out surface treatment make it possess the skin hardness of 2H ~ 3H for strengthening its adhesion strength.In three Cartesian coordinates in (X, Y, Z), if be aa ', aa from the line polarisation polarization direction of 2D display module layer 110 outgoing ' be parallel to Y-axis.Under the cold state of rotatory device layer 120, from the polarized light bb ' of rotatory device layer 120 outgoing parallel with X-axis because of polarization direction 90-degree rotation (aa ' ⊥ bb '), because the friction orientation direction rr ' of liquid crystal lens pillar layer 1300 is parallel with Y-axis, polarization direction be bb ' incident light by time the 3rd liquid crystal layer 1331 (referred to as liquid crystal layer 1331) because of polarization direction vertical with long axis of liquid crystal molecule in the 3rd liquid crystal layer 1331 (in figure, small circle represents that the major axis of liquid crystal molecule is vertical with paper), refractive index is no, because of the refractive index n=no of optical clear glue-line 1321, therefore do not reflect at the curved surface of Fresnel Lenses, now still show 2D.
As shown in Figure 9, under rotatory device layer 120 "on" position, its optically-active characteristic disappears, the linearly polarized light of aa ' the direction polarization of module layer 110 outgoing is shown by not changing its polarization state after rotatory device layer 120 from 2D, namely parallel with aa ' from the light polarization direction bb ' of rotatory device layer 120 injection.And the incident light of bb ' direction polarization state is for liquid crystal layer 1331, due to polarization direction bb ' and the long axis direction of liquid crystal molecule parallel (both are all parallel to Y-axis) in liquid crystal layer 1331, now refractive index is ne, refractive index because of optical clear glue-line 1321 is n, and meet n=no<ne, therefore the refraction effect will produced as convex lens on the curved surface of Fresnel Lenses, thus display 3D information.
Example 2:
Figure 10 is that the 3D of the bore hole 3D display device example 2 that the application provides shows schematic diagram.This 3D 3 d display device 2000 comprises three parts generally, i.e. backlight 210,2D display panel 220 and liquid crystal post lens 2300, wherein backlight 210 and 2D display panel 220 as identical in corresponding part in Fig. 3/Fig. 4 with existing 3 d display device, when 2D display panel 220 are selfluminous devices as during OLED then without the need to backlight 210 (in other words, can be understood as in 2D display panel 220 and include backlight 210).Liquid crystal post lens 2300 and liquid crystal post lens 230 difference of existing 3 d display device as shown in Fig. 3/Fig. 4 are, in this embodiment, on upper substrate 2321 (the 3rd substrate), form the curved-surface structure needed for Fresnel Lenses by Optical transparent adhesive 2351 (the second transparent optical glue-line), the liquid crystal layer 2331 encapsulated between upper substrate 2321 and infrabasal plate 2311 (tetrabasal) is filled and is formed Fresnel Lenses.If parallel with Y-axis from the linearly polarized light polarization direction of 2D display panel 220 outgoing, the alignment film rubbing direction being arranged on liquid crystal layer 2331 (being filled in the second transparent optical glue-line 2351 and the 4th electrode layer 2381) both sides is all parallel with Y-axis, when liquid crystal post lens jacket 2300 is in the state do not powered up, for positivity liquid crystal, due to long axis of liquid crystal molecule parallel with Y-axis (in figure, small circle represents that the major axis of liquid crystal molecule in liquid crystal layer 2331 is vertical with paper), from the Fresnel Lenses that the linearly polarized light parallel with Y-axis of 2D display panel 220 outgoing is formed through liquid crystal layer 2331, because of linearly polarized light polarization direction bb ' and liquid crystal layer 2331 longer axis parallel, refractive index is ne, and fresnel lens surface side Optical transparent adhesive 2351 refractive index is n, and ne > no=n, therefore reflect at fresnel lens surface, 3D can be shown.
As Figure 11, parallel with Y-axis from the linearly polarized light polarization direction of 2D display panel 220 outgoing, the alignment film rubbing direction being arranged on liquid crystal layer 2331 both sides is all parallel with Y-axis, electrode layer 2371 in liquid crystal post lens jacket 2300 and apply a larger driving voltage between electrode layer 2381, for positivity liquid crystal, because long axis of liquid crystal molecule is along direction of an electric field orientation i.e. parallel with Z axis (scheming the major axis that medium and small transverse represents liquid crystal molecule in liquid crystal layer 2331), the Fresnel Lenses refractive index formed through liquid crystal layer 2331 from the linearly polarized light in the bb ' direction of 2D display panel 220 outgoing is no, and fresnel lens surface side Optical transparent adhesive 2351 refractive index is n, and no=n, therefore do not reflect at fresnel lens surface, still carry out 2D display.
Example 3:
The Optical transparent adhesive 2351 used in optical clear glue-line 1321 used in example 1 and example 2 is all the glue compared with low-refraction, i.e. refractive index n and liquid crystal material birefraction (ne, no) one less in equal, to positivity liquid crystal material and n=no<ne.And high index of refraction Optical transparent adhesive in following embodiment, will be adopted, namely larger in Optical transparent adhesive refractive index n and liquid crystal material birefraction (ne, no) one is equal, to positivity liquid crystal material and n=ne>no.
As Figure 12 be the application the 2D of bore hole 3D display device example 3 that provides show schematic diagram.Rotatory device layer 120 in example 3 is identical with the rotatory device layer 120 in example 1, no longer repeat specification.Example 3 and example 1 (as Fig. 8,9) unlike, in the first example, flexible base plate 1311 is positioned at the side away from rotatory device layer 120, liquid crystal layer 1331 is positioned at the side near rotatory device layer 120, and Fresnel Lenses is formed by liquid crystal layer 1331, in addition, in the first embodiment frictional direction rr ' and the 2D of liquid crystal lens pillar layer 1300 to show module layer 110 emergent light polarization direction aa ' parallel.And in the third embodiment, flexible base plate 1312 (the second flexible base plate) is positioned at the side near rotatory device layer 120, liquid crystal layer 1332 is positioned at the side away from rotatory device layer 120, and Fresnel Lenses is formed by the Optical transparent adhesive 1322 of high index of refraction, in addition, in the 3rd example frictional direction rr ' and the 2D of liquid crystal lens pillar layer 3300 to show module layer 110 emergent light polarization direction aa ' vertical.At three Cartesian coordinates (X, Y, Z) in, if show the linearly polarized light polarization direction aa ' //X-axis of module layer 110 outgoing from 2D, under rotatory device layer 120 no power and OFF state, linearly polarized light 90-degree rotation after rotatory device layer 120 in aa ' direction is bb ' direction, bb ' is parallel with Y-axis, it is vertical that frictional direction rr ' (rr ' //Y) and 2D due to liquid crystal lens pillar layer 3300 show module layer 110 emergent light polarization direction aa ', the incident light of bb ' polarization direction when liquid crystal layer 1332 because its polarization direction is parallel with long axis of liquid crystal molecule (in figure, small circle represents that long axis of liquid crystal molecule is perpendicular to paper), refractive index is ne, and Optical transparent adhesive 1322 refractive index is n, and n=ne, therefore there is not refraction display 2D in fresnel lens surface part.
As Figure 13, if show the linearly polarized light polarization direction aa ' //X-axis of module layer 110 outgoing from 2D, disappear in rotatory device layer 120 energising and ON state By Rotatory characteristic, the linearly polarized light in aa ' direction is constant through rotatory device layer 120 rear polarizer direction, i.e. bb ' //aa ', it is vertical that frictional direction rr ' (rr ' //Y) and 2D due to liquid crystal lens pillar layer 3300 show module layer 110 emergent light polarization direction aa ', the incident light of bb ' polarization direction when liquid crystal layer 1332 because its polarization direction is vertical with long axis of liquid crystal molecule (in figure, small circle represents that long axis of liquid crystal molecule is perpendicular to paper), refractive index is no, and Optical transparent adhesive 1322 refractive index is n, and n=ne>no, therefore in fresnel lens surface position because generation refraction is converged thus display 3D by refractive index difference.
Example 4:
As Figure 14 be the application the 2D of bore hole 3D display device example 4 that provides show schematic diagram.With example 2 (as Figure 10, Figure 11) unlike, the Optical transparent adhesive 2351 used in the liquid crystal post lens 2300 of example 2 is arranged on upper substrate 2321, filled by liquid crystal layer 2331 and form Fresnel Lenses, and in this embodiment (example 4), high index of refraction Optical transparent adhesive 2352 is arranged on infrabasal plate 2312 (the 6th substrate), and forming Fresnel lens structure by Optical transparent adhesive 2352, liquid crystal layer 2332 is arranged on Fresnel Lenses 2352.At three Cartesian coordinates (X as shown in the figure, Y, Z) in, if from the linearly polarized light polarization direction bb ' //Y-axis of 2D display panel 220 outgoing, when liquid crystal layer 2332 (the second liquid crystal layer) the friction orientation direction rr ' //Y-axis of liquid crystal post lens jacket 4300 inside, under no power state (without pressure reduction between electrode layer 2372 and electrode layer 2382), because long axis of liquid crystal molecule in liquid crystal layer 2332 is parallel with Y-axis, (in figure, small circle represents the vertical paper of long axis of liquid crystal molecule in liquid crystal layer 233, namely parallel with Y-axis), polarization direction is the incident light of bb ' is ne to the refractive index of liquid crystal layer 2332, because Optical transparent adhesive 2352 refractive index is n, and meet n=ne, therefore the difference of liquid crystal layer 2332 refractive index is there is not at fresnel lens surface place, there is not refraction directly by liquid crystal post lens 4300 thus display 2D in incident light.As shown in Figure 14,15, liquid crystal post lens jacket 4300, from top to bottom, upper substrate 2322 (the 5th substrate), electrode layer 2372 (the 5th electrode layer), liquid crystal layer 2332 (the second liquid crystal layer), optical clear glue-line 2352 (forming the Optical transparent adhesive of Fresnel Lenses unit), electrode layer 2382 (the 6th electrode layer) and infrabasal plate 2312 (the 6th substrate) is disposed with.
As Figure 15, if from the linearly polarized light polarization direction bb ' //Y-axis of 2D display panel 220 outgoing, when the inner liquid crystal layer 2332 friction orientation direction rr ' //Y-axis of liquid crystal post lens 4300, (pressure reduction between electrode layer 2372 and electrode layer 2382 is enough to change liquid crystal molecule initial orientation in liquid crystal layer 2332 in the energized state, thus make molecular long axis along direction of an electric field and Z axis arrangement), (in figure, long axis of liquid crystal molecule in liquid crystal layer 2332 is represented with little transverse because long axis of liquid crystal molecule in liquid crystal layer 2332 is parallel with Z axis, namely parallel with Z axis), polarization direction is the incident light of bb ' is no to the refractive index of liquid crystal layer 2332, because Optical transparent adhesive 2352 refractive index is n, and meet n=ne>no, therefore occur to reflect because of the difference of refractive index at fresnel lens surface place thus show 3D.
In above four embodiments, after adopting Fresnel Lenses to replace existing convex lens, because sagitta reduces (h ' h/2) greatly, can contribute to carrying out the coating of PI alignment films and friction on lens curved surface, be described for friction as shown in figure 16.For the existing apparatus (the left figure of Figure 16) adopting convex lens structures to realize stereo display, because lens have larger sagitta h in friction process, high some A of lens arrangement and pole low spot B is caused to there is larger vertical section poor, the PI alignment films being formed at surface is subject to the intensity difference of friction cloth friction, cause its orientation capacity variance very large, affect the consistance of liquid crystal molecular orientation.And adopt the 3 d display device of Fresnel lens structure (right figure of Figure 16) in friction process, because sagitta h ' can be reduced to more than at least 50%, significantly can improve lens arrangement high some A ' poor with the vertical section at low spot B ' place, pole, reduce diverse location PI alignment film rubbing strength difference, improve the orientation consistance of liquid crystal molecule, be convenient to obtain less crosstalk when 3D shows, improve display quality.
As the structural representation that Figure 17 is each example, at three Cartesian coordinates (X, Y, Z) in, for example 1,3, liquid crystal lens pillar layer 1300/3300 is positioned at the side near observer, rotatory device layer 120 is arranged at 2D and shows between module layer 110 and liquid crystal lens pillar layer 1300/3300, for example 2,4, liquid crystal post lens 2300/4300 are positioned at the side near observer, and 2D display panel 220 is arranged between backlight 210 and liquid crystal post lens 2300/4300.If the axis direction ss ' of Fresnel Lenses unit is α (0≤α≤40 degree with Y-axis angle, the angle of recommending is 72 degree), spacing (pitch) between each lenticule is p, at the projected length px=p/cos α of X-direction, when α=0 degree px=p also each lenticule extend all along the Y direction, and when α ≠ 0, px > p is also each lenticule is all certain angle of inclination with Y-axis, fine setting inclination alpha can change the size of lens unit at X-direction projection px, thus fine setting 3D visible angle, and eliminate the impact of Morie fringe.
Adopt the bore hole 3D 3 d display device that Fresnel lens structure is formed, compare the existing 3 d display device utilizing convex lens to realize 3D display, because the sagitta of lens unit reduces over half, be convenient to form lens coating needed for 3 d display device or substrate reduces vertical section difference in PI printing and friction process, improve the consistance of PI alignment film rubbing intensity and the consistance of liquid crystal molecular orientation, thus reduce the crosstalk of 3D display device, improve display effect;
For the 3 d display device adopting liquid crystal post lens, the sagitta of lens unit reduces more than 1/2, thickness of liquid crystal layer d is reduced greatly, due to liquid crystal cell response time t ∝ d2, therefore can make the response time be reduced to original 3 d display device 25% or less, improve 2D/3D switch speed, provide possibility for high-frequency drive (>=120HZ) realizes full HD 3D display;
Compare former convex lens due to Fresnel Lenses and have less focal length, the 3 d display device of formation has shorter 3D viewing distance, is therefore more suitable at individual consumer's goods as the handheld device such as mobile phone, flat board field uses;
Because adopting the 3 d display device sagitta of Fresnel Lenses to reduce more than 1/2, thickness of liquid crystal layer d reduces greatly, significantly can reduce and use liquid crystal consumption, reduces cost of products.
