During crystal coating 143, because the polarization direction of incident light is vertical with long axis of liquid crystal molecule direction in liquid crystal coatings 143, then liquid crystal is applied
Refractive index is ordinary refraction index n for layer 143o。
As shown in figure 3, because the refractive index of lens microstructure 142 is more than ordinary refraction index, therefore from liquid crystal coatings 143
Light when entering lens microstructure 142, enter optically denser medium from optically thinner medium equivalent to incident light, understand according to the law of refraction
Light is penetrated to draw close to normal.It is thereby achieved that information corresponding to the left eye that the odd number sub-pixel column of 2D display units 130 is shown can
To be sent to the left eye of observer after the refraction of liquid crystal lens unit 141, the even sub-pixel columns of 2D display units 130 are shown
Right eye corresponding to information can be sent to the right eye of observer after the refraction of liquid crystal lens unit 141, make observer can be with
See correct image information.
In the next frame of present frame, the first polarization state adjustment unit 110 is still within to electricity condition, and makes first
One of one electrode of electrode layer 112 either multiple electrodes and the second electrode lay 114 exists between electrode or multiple electrodes
Voltage difference；Second polarization state adjustment unit 120 is adjusted to the state to electricity, makes the 3rd electrode layer 122 one or more
Voltage difference is not present between one or more electrode of electrode and the 4th electrode layer 124.At this point it is possible to it is the first polarization state
The polarization state adjustment unit 120 of adjustment unit 110 and second is in the second default operating condition, i.e. the first liquid crystal layer 113 with
And second the liquid crystal molecule of liquid crystal layer 123 lose optically-active characteristic, make the linear polarization for being incident to the first polarization state adjustment unit 110
The polarization characteristic of light is not changed, and the polarization characteristic for being incident to the linearly polarized light of the second polarization state adjustment unit 120 is not sent out
It is raw to change.So as to make the linearly polarized light that 2D display units 130 are emitted special by the rear polarizer of the second polarization state adjustment unit 120
Property does not change, then during by the first polarization state adjustment unit 110, polarization characteristic does not change, and is further incident to liquid crystal
During the liquid crystal coatings 143 of lens unit 141, because of polarization direction and the long axis of liquid crystal molecule direction in liquid crystal coatings 143 of incident light
Parallel, then refractive index is extraordinary ray refractive index n for liquid crystal coatings 143e。
As shown in figure 4, because the refractive index of lens microstructure 142 is less than extraordinary ray refractive index, therefore from liquid crystal coatings
When 143 light enters lens microstructure 142, enter optically thinner medium from optically denser medium equivalent to incident light, can according to the law of refraction
Know, incident light off-normal, the odd number sub-pixel column of 2D display units 130 and even sub-pixel columns are handed over during the next frame of present frame
After changing right and left eyes information, it is saturating that information corresponding to the right eye that the odd number sub-pixel columns of 2D display units 130 is shown can pass through liquid crystal
Mirror unit 141 is sent to the right eye of observer after reflecting, corresponding to the left eye that the even sub-pixel columns of 2D display units 130 are shown
Information can be sent to the left eye of observer after the refraction of liquid crystal lens unit 141, observer is can see correct figure
As information.
So as to reference to the display mode of present frame and the next frame of present frame, it is possible to achieve the 3 d display device 100
3D display state, and due in 120 frames per second, the information of left eye is shown with the time odd number sub-pixel column of half,
Even sub-pixel columns show the information of right eye, and second half time odd number sub-pixel column shows the information of right eye, even sub-pixel
Row show the information of left eye, each frame is all shown the information of left eye or the information of right eye.So that stereoscopic display fills
100 are put when carrying out 3D display, resolution ratio is not lost, and makes the 3D display effect promoting of 3 d display device 100.
In embodiments of the present invention, when one or more electrode and the one of the second electrode lay 114 of first electrode layer 112
Voltage difference is not present between individual or multiple electrodes；One or more electrode and the 4th electrode layer 124 of 3rd electrode layer 122
One or more electrode between voltage difference is not present.I.e. incident light passes through the rear polarizer of the second polarization state adjustment unit 120
Direction is rotated by 90 °, then selects 45 ° by polarization direction during the first polarization state adjustment unit 110, hence into liquid crystal layer
When, refractive index corresponding to liquid crystal coatings 143 isTherefore, as shown in figure 5, liquid crystal coatings 143 are right
The refractive index for the light that liquid crystal coatings 143 should be incident to by the first polarization state adjustment unit 110 is identical with first refractive index, from
And light when passing through liquid crystal coatings 143 and lens microstructure 142 refractive index do not change so that 2D display units 130 are shown
Image information enter the left eye and right eye of access customer simultaneously, realize 2D dispaly states, and resolution ratio is not lost.
3 d display device 100 provided in an embodiment of the present invention, it is possible to achieve 3D display state and 2D dispaly states, and
All have and when 3D display state and 2D dispaly states, resolution ratio is not lost, i.e. under two kinds of dispaly states preferably aobvious
Show effect.
