Specific embodiment
Exemplary embodiment of the invention is more fully described below with reference to accompanying drawings.Although being shown in accompanying drawing
Exemplary embodiment of the invention, it being understood, however, that may be realized in various forms the present invention without should be by
Embodiments set forth here is limited.Conversely, there is provided these embodiments are able to be best understood from this
Invention, and can by the scope of the present invention it is complete convey to those skilled in the art.
Embodiment one
As shown in Figure 1 to Figure 3, The embodiment provides a kind of liquid crystal lens, including：It is relative to set
The first substrate 1 and second substrate 2 put, and the liquid crystal between first substrate 1 and second substrate 2
Layer 3, the liquid crystal layer 3 is made up of multiple liquid crystal molecules.Wherein, first substrate 1 is close to the one of liquid crystal layer 3
Face is provided with the first electrode 5 of multiple bar shapeds, and first electrode 5 is on the pixel cell 4 of display panel
Projection is in first angle with one side of pixel cell 4；Second substrate 2 is provided near the one side of liquid crystal layer 3
The second electrode 6 of multiple bar shapeds, and projection and picture of the second electrode 6 on the pixel cell 4 of display panel
One side of plain unit 4 is in second angle.Wherein, the orientation of pixel cell 4 includes：With first direction
Parallel first order direction, and the second order direction vertical with first direction.Specifically, the first electricity
Projection of the pole 5 on the pixel cell 4 of display panel is in first jiao with the first order direction of pixel cell 4
The first order side of degree, projection of the second electrode 6 on the pixel cell 4 of display panel and pixel cell 4
To in second angle.First electrode 5 and second electrode 6 are inclined with the orientation of pixel cell 4 certain
Angle, may be such that each lens unit can light splitting in first order direction and second order direction so that screen
Curtain can be presented clearly stereoeffect when transverse and longitudinal overturns and switches；Further, it is also possible to eliminate the shadow of moire fringes
Ring, improve stereo display effect.When liquid crystal lens are used for stereoscopic display, respectively first electrode 5 and the
Two electrodes 6 apply different voltages, and electrical potential difference is formed between first substrate 1 and second substrate 2, from
And drive the liquid crystal molecule of liquid crystal layer 3 that certain deflection occurs, the liquid crystal lens unit of gradually changed refractive index is formed,
Liquid crystal lens unit can be adjusted to light, so that stereo-picture is presented.Wherein, because display screen is horizontal
With it is longitudinal when Aspect Ratio it is different, therefore first electrode 5 and second electrode 6 arragement direction and arrangement angle
Degree is different, i.e., be not parallel to each other between first electrode 5 and second electrode 6.
Wherein, when display screen is horizontal or it is longitudinal when, first electrode 5 is different with the effect of second electrode 6,
And the voltage that it applies also is differed, it is assumed that when screen is in transverse screen, using first electrode 5 as driving
Electrode, using second electrode 6 as public electrode, and applies different voltages, to drive liquid crystal to it respectively
The liquid crystal molecule of layer 3 deflects, and forms lens unit, realizes horizontal stereo display effect.When screen
Placement location changes, i.e., when transverse screen is changed into vertical screen, using first electrode 5 as public electrode, by second
Electrode 6 applies different voltages to it respectively as driving electrodes, to drive the liquid crystal point of liquid crystal layer 3
Son deflects, and forms lens unit, realizes longitudinal stereo display effect.It is worthy of note that, display screen
Curtain is horizontal or longitudinal corresponding driving electrodes and public electrode can be exchanged, and only needs applied voltage to meet lens need
Ask.
Wherein, it is spaced between multiple first electrodes 5 to set on first substrate 1, multiple second electrodes
Between 6 spaced setting on second substrate 2, i.e., two neighboring first electrode 5 or two second electrodes
Between 6 between be separated with certain distance.Because first electrode 5 and second electrode 6 are possible as common electrical
Pole and driving electrodes, the stereo display effect horizontal or longitudinal in order to ensure display screen, the width of electrode with
And the distance between adjacent electrode needs to meet certain requirements, and arranged according to the cycle.Drawn through experiment,
Electrode width is larger than electrode spacing, and generally, the ratio of electrode width and electrode spacing is more than
0.7 is less than 3.That is, the width of first electrode 5 and first electrode 5 and its adjacent first
The ratio of the distance between electrode 5 is 0.7 to 3, similarly the width of second electrode 6 and second electrode 6 and
The ratio that it is adjacent to the distance between second electrode 6 is 0.7 to 3.Preferably, electrode width and electrode
When the ratio of spacing is 1 to 1.5, stereo display effect is preferable.
Specifically, it is parallel to each other between multiple first electrodes 5, is parallel to each other between multiple second electrodes 6,
But due to display screen it is horizontal with it is longitudinal when Aspect Ratio it is different, and the arragement direction of pixel cell 4 is different,
Therefore it is the arragement direction of the stereo display effect that raising is horizontal and longitudinal, first electrode 5 and second electrode 6
Difference, i.e., above-mentioned first angle is different from second angle.That is, although multiple first electrodes 5 or many
It is parallel to each other between individual second electrode 6, arrangement, but first electrode 5 and second is extended according to unified angle
In the absence of the relation that is parallel to each other between electrode 6.
The structure to liquid crystal lens of the invention is made that simple introduction above, below in conjunction with concrete application
Scape powers up mode to it and stereoscopic display is further explained explanation.
Specifically, as shown in figure 4, when display screen is horizontal, first electrode 5 is used as driving electrodes, position
The different first voltage of intensity is applied in the first electrode 5 of diverse location, second electrode 6 is used as common electrical
Pole, is that it applies intensity identical second voltage, and the voltage difference between second voltage and first voltage is formd
The first electric field between first electrode 5 and second electrode 6, i.e., between first substrate 1 and second substrate 2
The first electric field is formed with, under the driving effect of the first electric field, the arragement direction of the liquid crystal molecule of liquid crystal layer 3
Deflect, and yawing moment and angle are not quite similar, therefore form multiple horizontal lens units；It is worth referring to
Go out, be first electrode 5 apply first voltage intensity by horizontal lens unit center to two ends according to
Secondary enhancing；And the voltage strength phase applied along the symmetrical first electrode 5 in the center both sides of horizontal lens unit
Deng unified pressurization can be used to it, or pressurizeed respectively.
Wherein, the electrode of horizontal lens unit is distributed according to centrosymmetric mode, and second voltage is electric with first
Voltage difference between pressure, is raised, i.e., successively by the center of horizontal lens unit to the two ends of horizontal lens unit
The intensity of the first electric field is strengthened successively by the center of horizontal lens unit to two ends.
Specifically, as shown in figure 5, when display screen is longitudinal, first electrode 5 is as public electrode
It applies intensity identical tertiary voltage, second electrode 6 as driving electrodes, positioned at the of various location
Two electrodes 6 are applied in the 4th different voltage of intensity, and the voltage difference between tertiary voltage and the 4th voltage is formed
The second electric field between first electrode 5 and second electrode 6, i.e., in first substrate 1 and second substrate 2
Between be formed with the second electric field, under the driving effect of the second electric field, the arrangement of the liquid crystal molecule of liquid crystal layer 3
Direction deflects, and yawing moment and angle are not quite similar, therefore forms multiple longitudinal lens units；Value
, it is noted that the intensity of the 4th voltage applied for second electrode 6 by the center of longitudinal lens unit to two
End strengthens successively；And it is strong along the voltage that the symmetrical second electrode 6 in the center both sides of longitudinal lens unit is applied
Degree is equal, unified pressurization can be used to it, or pressurizeed respectively.
Wherein, the electrode of longitudinal lens unit is distributed according to centrosymmetric mode, tertiary voltage and the 4th electricity
Voltage difference between pressure, is raised, i.e., successively by the center of longitudinal lens unit to the two ends of longitudinal lens unit
The intensity of the second electric field is strengthened successively by the center of horizontal lens unit to two ends.It is worthy of note that, along vertical
Put the voltage strength that the symmetrical electrode in center both sides of lens unit applied equal, it can be used it is unified plus
Pressure, or pressurizeed respectively.
By Fig. 4 and Fig. 5 can be seen that when display screen be in horizontal and longitudinal state when, the first electric field with
The direction of the second electric field is different, therefore the offset direction of the liquid crystal molecule of liquid crystal layer 3 is different, the lens of formation
The direction of unit is different.
In order to further illustrate, the present embodiment by taking 5.5 cun of display screens of 1080P as an example, in display screen
When horizontal, the Design of length of horizontal lens unit is 210 microns, angle be it is left-leaning 72 °, corresponding the
The electrode width of one electrode 5 and second electrode 6 be 16 microns, between two neighboring first electrode 5 away from
From or the distance between two neighboring second electrode 6 be the adjacent first electrode of 14 microns, i.e., 75 and the
Liquid crystal molecule between two electrodes 6 is configured to a horizontal lens unit, and with the center of horizontal lens unit
Symmetrical pressurization, the voltage that symmetrical first electrode 5 applies is equal；When display screen is longitudinal, longitudinal lens
The length of unit is 192 microns, and angle is 60 ° of Right deviation, corresponding first electrode 5 and second electrode 6
Electrode width be 16 microns, the distance between two neighboring first electrode 5 or two neighboring second electrode
The distance between 6 is the liquid crystal point between the adjacent first electrode of 16 microns, i.e., 65 and second electrode 6
Son is configured to a horizontal lens unit, and is pressurizeed with the Central Symmetry of longitudinal lens unit, and symmetrical second
The voltage that electrode 6 applies is equal.Or,
When display screen is horizontal, the Design of length of horizontal lens unit is 192 microns, and angle is "Left"-deviationist
72 °, the electrode width of corresponding first electrode 5 and second electrode 6 is 16 microns, two neighboring first
The distance between electrode 5 or the distance between two neighboring second electrode 6 are 16 microns, i.e., 6 adjacent
Liquid crystal molecule between first electrode 5 and second electrode 6 is configured to a horizontal lens unit, and with horizontal
The Central Symmetry pressurization of lens unit, the voltage that symmetrical first electrode 5 applies is equal；It is vertical in display screen
When putting, the length of longitudinal lens unit is 192 microns, and angle is 60 ° of Right deviation, corresponding first electrode 5
It is 16 microns, the distance between two neighboring first electrode 5 or adjacent with the electrode width of second electrode 6
The distance between two second electrodes 6 are the adjacent first electrode of 16 microns, i.e., 65 and second electrode 6
Between liquid crystal molecule be configured to a horizontal lens unit, and pressurizeed with the Central Symmetry of longitudinal lens unit,
The voltage that symmetrical second electrode 6 applies is equal.It is worthy of note that, horizontal lens unit or longitudinal lens
The design length of unit and inclination angle are according to the arrangement of pixel cell 4 and viewing distance design, with display
The size of screen does not have much relations.
Further, when display screen carries out 2D displays, the color point that may there is spacer is existing
As in order to avoid this harmful effect as far as possible, as shown in fig. 6, embodiments of the invention are to first electrode
5 and second electrode 6 be subject to the voltage of varying strength respectively, to form certain voltage difference between two-layer electrode,
Eliminate the color point phenomenon of spacer.Specifically, it is that first electrode 5 applies the voltage of intensity identical the 5th, is
Second electrode 6 applies the voltage of intensity identical the 6th, and the voltage difference between the 5th voltage and the 6th voltage is formed
The 3rd relatively uniform electric field, in the presence of the 3rd electric field, the deflection of each liquid crystal molecule of liquid crystal layer 3
The arragement direction of direction and angle all same, i.e. liquid crystal molecule is consistent, therefore liquid crystal layer 3 will not form lens
Unit, does not possess lens effect.
Because power-up mode when display screen is horizontal and longitudinal occurs certain difference, and horizontal or
2D and 3D two states occur in the state of longitudinal, it is therefore desirable to which backstage is judged and then provided phase
The control voltage answered.
For example：Display screen by horizontal power-up 2D to horizontal 3D states, it is necessary to a judgement for state,
Then the hand-off process of voltage is carried out again；By horizontal 2D to longitudinal 3D states, it is necessary to state is sentenced
It is fixed, the hand-off process of voltage is then carried out again；Screen by horizontal 2D to longitudinal 2D situation, can not
Do the hand-off process on voltage；If by horizontal 3D to longitudinal 3D states, it is necessary to be carried out on voltage
Certain hand-off process；If by horizontal 3D to horizontal 2D states, it is necessary to a judgement for state, so
Carry out the hand-off process of voltage again afterwards；If by horizontal 3D to longitudinal 2D states, it is necessary to state
Judge, the hand-off process of voltage is then carried out again；The above is several vice-versa, as the same.These hand-off process
A medium voltage state can be included, so that these states can quickly be switched.
