When light passes through lens microstructure 122 again, orientation refraction occurs.When sub-pixel corresponding to 2D display units 130 shows have respectively
During the right and left eyes image of certain parallax, sub-pixel on 2D display units 130 is presented after the refraction of liquid crystal lens unit 120
Left eye information and right eye information are refracted into the left eye and right eye of people respectively, observer is obtained stereoscopic vision.The display shape
Under state, to the light of incidence orientation refraction can occur for all positions of liquid crystal lens unit 120, therefore be accomplished that the first 3D
Dispaly state, i.e., full stereoscopic display state.
When each lenticule unit 124 centre position or both ends face the second electrode lay 117 the second electrode lay
In electrode 118 and at least one first electrode layer electrode 113 of first electrode layer 112 between each first electrode layer electrode 113
In the absence of the voltage difference for meeting the second preparatory condition, remaining the second electrode lay electrode 118 and first electrode of the second electrode lay 117
Exist at least one first electrode layer electrode 113 of layer 112 between each first electrode layer electrode 113 and meet the second default bar
During the voltage difference of part, first electrode layer electrode 113 of the light Jing Guo first electrode layer 112 that is emitted due to 2D display units 130 and
The second electrode lay electrode 118 of the second electrode lay 117 exist the polarization direction after the liquid crystal layer 115 of the position face of voltage difference with
The arragement direction of liquid crystal coatings 123 is consistent, first electrode layer of the light that 2D display units 130 are emitted Jing Guo first electrode layer 112
After the liquid crystal layer 115 for the position face that voltage difference is not present in the second electrode lay electrode 118 of electrode 113 and the second electrode lay 117
Polarization direction it is vertical with the arragement direction of liquid crystal coatings 123, therefore, with the of first electrode layer 112 in the second electrode lay 117
The liquid crystal coatings 123 that the face of the second electrode lay electrode 118 of voltage difference is not present in one electrode layer electrode 113 are corresponding by polarizing shape
The refractive index that state adjustment unit 110 is incident to the light of liquid crystal coatings 123 is no, in the second electrode lay 117 with first electrode layer 112
The liquid crystal coatings 123 of the face of the second electrode lay electrode 118 that voltage difference be present of first electrode layer electrode 113 corresponding pass through
The refractive index that polarization state adjustment unit 110 is incident to the light of liquid crystal coatings 123 is ne.So as to refer to Fig. 3 or Fig. 4, often
Orientation does not occur to the light of incidence and reflects for the centre position or both ends of individual lenticule unit 124, and each lenticule unit 124
To the light of incidence orientation refraction occurs for remaining position.Also, the of the relative the second electrode lay 117 of each lenticule unit 124
The second electrode lay electrode of voltage difference in two electrode layer electrodes 118 with the first electrode layer electrode 113 of first electrode layer 112 be present
118 number, account for the ratio of the total number of the second electrode lay electrode 118 of the relative the second electrode lay 117 of each lenticule unit 124
Example should be more than or equal to 60%, so as to so that most of position of each lenticule unit 124 can be to the light of incidence
Produce orientation refraction, when sub-pixel shows the right and left eyes image with certain parallax respectively corresponding to 2D display units 130, warp
Cross after liquid crystal lens unit 120 reflects the left eye information that sub-pixel on 2D display units 130 is presented and right eye information is distinguished
The left eye and right eye of people are refracted into, observer is obtained stereoscopic vision；And the centre position of each lenticule unit 124 or
End positions the light of incidence do not occur orientation refraction, the information of the sub-pixel of 2D display units 130 can be made into observation simultaneously
The left eye and right eye of person receives, that is, contains part 2D display informations.It is thus possible to the second 3D display state is realized, and second
The resolution ratio of 3D display state is more than the resolution ratio of the first 3D display state.
In embodiments of the present invention, the first preparatory condition can be identical with the second preparatory condition, for example, the first preparatory condition
And second default regulation can be 20V.Certainly, the first preparatory condition can also be different from the second preparatory condition, for example, the
One preparatory condition is 15V, and the second preparatory condition is 20V.It should be noted that the first preparatory condition of the above and the second default bar
The numerical value of part is only for example, and the concrete numerical value of the first preparatory condition and the second preparatory condition is not intended as limiting.
When each electrode in one or more of electrodes of the first electrode layer 112 and the second electrode lay
When voltage difference being not present between each electrode in 117 the multiple electrode, because the light that 2D display units 130 are emitted passes through
Polarization direction after the polarization state adjustment unit 110 is vertical with the orientation of the pixel column, and therefore, the liquid crystal applies
The refractive index of the corresponding light for being incident to the liquid crystal coatings 123 by the polarization state adjustment unit 110 of layer 123 is no.From
And refer to Fig. 5, it is possible to achieve when being incident to the light of liquid crystal coatings 123 and passing through lens microstructure 122 again, orientation folding does not occur
Penetrate.The information of sub-pixel from 2D display units 130 is all received by the left eye of people and right eye simultaneously, realizes that 2D shows shape
State.
