Inner side.When liquid crystal lens are in running order, for a lens unit, first electrode 104 and planar sub-electrode 51
The current potential for being loaded is equal, planar sub-electrode 51 and ring-type sub-electrode 52 according to order loading from inside to outside current potential gradually
Raise, thus, the liquid crystal molecule inside lens unit is deflected in the presence of electric field and is equivalent to hemispherical lens, and the hemispherical is saturating
The refractive index of mirror is centrosymmetric distribution along center, is gradually reduced from center to marginal position, this is because in lens list
Planar sub-electrode when unit is in running order positioned at center is equal with the voltage that first electrode is loaded so that positioned at centre bit
The liquid crystal molecule put does not deflect in original state, the plane that the longer axis parallel of liquid crystal molecule is located in electrode, and makes
The refractive index of center is close to ne, and the liquid crystal molecule at edge is located in the electricity produced by ring-type sub-electrode and first electrode
At utmost deflect in the presence of, the plane that the major axis of liquid crystal molecule is located perpendicular to electrode makes the refractive index of marginal position
Close to no, the polarization degree of the liquid crystal molecule between center and marginal position is not by deflecting to deflection completely
For at utmost gradually transition, refractive index is in noTo neBetween, the index distribution for thus making each position in liquid crystal lens more connects
Nearly ideal delay curve, improves the effective rate of utilization of liquid crystal lens.
The top view of the second electrode 104 of above-mentioned liquid crystal lens provided in an embodiment of the present invention as shown in Fig. 4 a- Fig. 4 c, face

Shape etc..Optionally, the outline of ring-type sub-electrode 52 can be circular or regular polygon.Planar sub-electrode 51 is located at ring-type sub-electrode
The center of 52 center, planar sub-electrode 51 and ring-type sub-electrode 52 overlaps, and planar sub-electrode 51 and ring-type sub-electrode
52 interval is equal, i.e. the inward flange everywhere of ring-type sub-electrode 51 is all equal apart from the beeline of planar sub-electrode 51.Will
Planar sub-electrode 51 and ring-type sub-electrode 52 arrange at equal intervals can when to 105 applied voltage of first electrode 104 and second electrode,
Symmetrical electric field is formed between electrodes, so that liquid crystal molecule is consistent in symmetric position degree of deflection.
Further, as shown in Fig. 4 a- Fig. 4 c, the Internal periphery of ring-type sub-electrode 52 and the shape of outline are electric with planar
The outline of pole 51 is identical, and symmetric figure centered on the electrode pattern of ring-type sub-electrode 52 and planar sub-electrode 51.That is planar
Sub-electrode 51 is consistent with the figure of ring-type sub-electrode 52.Such as, planar sub-electrode 51 is circle, then ring-type sub-electrode 52 is circle
Ring, preferably, ring-type sub-electrode 52 is the annulus with the circular planar sub-electrode 51 for concentric circles.

The shape of pole 51 can be regular hexagon.Additionally, the shape of planar sub-electrode 51 can also be other regular polygons, ring-type sub-electrode 52
There is identical graph outline with planar sub-electrode 51, it is numerous to list herein.
The delay curve of each lens unit in liquid crystal lens of the prior art and ideal delay curve comparison figure such as Fig. 5
It is shown, wherein, O represents the center of liquid crystal lens, and the liquid-crystal refractive-index of center is n to the maximummax, prolong to surrounding from centered on O points
The refractive index for stretching liquid crystal molecule is gradually reduced, and to edge liquid-crystal refractive-index minimum of a value n is reduced tomin, the refractive index of transitional region
neffIn maximum nmaxWith minimum of a value nminBetween.As can be seen from Figure, the center O of liquid crystal lens of the prior art
Refractive index maximum n at placemax<ne, and it is located at refractive index minimum of a value n of edgemin>no, this is because right in prior art
During two electrode applied voltages, the trend that the oriented center of fringe field formed positioned at the plane-shape electrode of upper substrate is drawn close, in making
Originally the liquid crystal molecule to be remained unchanged deflects the heart, so as to the refractive index of center is diminished, makes prolonging for center
Late curve is dragged down.
And the second electrode 105 in above-mentioned liquid crystal lens provided in an embodiment of the present invention includes being located at the planar of center
Sub-electrode 51 and peripherally located ring-type sub-electrode 52.When to liquid crystal lens applied voltage, the liquid crystal molecule in liquid crystal layer 103
Deflection situation as shown in fig. 6, due to make be located at center planar sub-electrode 51 it is equal with the current potential of first electrode, so as to
So that the liquid crystal molecule of center is not affected to keep original state, and refractive index n of center by fringe fieldmaxMore
Close ne, refractive index n of marginal positionminCloser to no, so that the delay curve of each lens unit is closer in liquid crystal lens
Ideal delay curve, as shown in Figure 7.Further, due to retardation Retadation=Δ n × d × liquid crystal effective rate of utilization,
Wherein, Δ n=ne-noDetermined by liquid crystal self property, be certain value, d is that liquid crystal cell is thick, is also certain value.
Therefore, put forward retardation Retadation when using above-mentioned liquid crystal lens structure provided in an embodiment of the present invention
Height, so as to improve the effective rate of utilization of liquid crystal.
In the specific implementation, one or more can be set according to the periodic dimensions of the equivalent hemispherical lens of lens unit

Individual ring-type sub-electrode 52；And the lens unit equivalent lens cycle it is larger when, second electrode 105 then need arrange it is multiple
Ring-type sub-electrode 52.So that second electrode 105 includes circular planar sub-electrode 51 and circular sub-electrode 52 as an example, in lens unit
The equivalent lens cycle it is less when, second electrode structure as shown in fig. 4 a, only including a circular sub-electrode 52；In lens
When the unit equivalent lens cycle is larger, second electrode structure is as shown in figure 8, including multiple circular sub-electrodes 52.
Further, the embodiment of the present invention only includes a ring-type using TechWiz liquid crystal simulation software to second electrode
In the case of sub-electrode, the experiment of the liquid crystal effective rate of utilization of planar sub-electrode and ring-type sub-electrode in the case of different in width.Its
Experimental result is as shown in the table：
As can be seen from the above table when ring-type sub-electrode 52 width W2 and planar sub-electrode 51 Breadth Maximum W1 ratio W2/
The effective rate of utilization that W1 is set smaller than liquid crystal when 0.5 is higher.
In another kind of enforceable mode, when second electrode 105 includes multiple ring-type sub-electrodes 52, as shown in figure 8,
Each ring-type sub-electrode 52 expands outwardly successively distribution centered on planar sub-electrode 51；And it is in running order in liquid crystal lens
When, the voltage that each ring-type sub-electrode 52 is loaded increases successively from inside to outside.
