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, the corresponding information of right eye that the odd number sub-pixel column of 2D display units 130 is shown can be saturating by liquid crystal
Mirror unit 120 is sent to the right eye of observer after reflecting, the left eye that the even sub-pixel columns of 2D display units 130 are shown is corresponding
Information can be sent to the left eye of observer after the refraction of liquid crystal lens unit 120, and observer is made to can see correct figure
As information.
So as to reference to the display mode of present frame and the next frame of present frame, realize 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, the other half time odd number sub-pixel column shows the information of right eye, even sub-pixel
Row show the information of left eye, and each frame is made all to show the information of left eye or the information of right eye.So that stereoscopic display dress
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, can be that there are the first predeterminated voltage is poor with the second electrode lay 114 for first electrode layer 112
When, make the first liquid crystal layer 113 that incident linearly polarized light polarization angle be changed 90 degree for 90 degree of liquid crystal molecule natural distortion,
So as to fulfill the first polarization adjustment state.Can be that there are the second predeterminated voltage is poor with the second electrode lay 114 for first electrode layer 112
When, the liquid crystal molecule of the first liquid crystal layer 113 is made to lose optically-active characteristic, the polarization direction for making incident line style polarised light is constant, from
And realize the second polarization adjustment state.
Specifically, the first predeterminated voltage difference can be poor less than the second predeterminated voltage.Wherein, the first predeterminated voltage difference can be
0, the second predeterminated voltage difference is that the liquid crystal molecule of the first liquid crystal layer 113 can be made to lose the voltage difference of optically-active characteristic.Certainly, first
The concrete numerical value of predeterminated voltage difference and the second predeterminated voltage difference is not intended as limiting in embodiments of the present invention.
In embodiments of the present invention, under 2D dispaly states, there are thirds with the second electrode lay 114 for first electrode layer 112
During predeterminated voltage difference, polarization state adjusts unit 110 and is in third polarization adjustment state.Liquid crystal coatings 123 are corresponded to from first partially
The refractive index of light that status adjustment of shaking unit 110 is incident to liquid crystal coatings 123 is identical with first refractive index, so that 2D display units
The image informations of 130 displays simultaneously into the left eye and right eye of access customer, wherein, third predeterminated voltage difference is between the first default electricity
Between pressure difference and the second predeterminated voltage difference.
Wherein, third predeterminated voltage difference is between the first predeterminated voltage difference and the second predeterminated voltage difference.Third presets electricity
Pressure difference makes the half liquid crystal molecule in the first liquid crystal layer 113 lose optical activity, 90 ° of half liquid crystal molecule natural distortion, thus will
