First display screen, 2 array is provided with multiple rgb pixels, in the embodiment shown in fig. 1, only takes out single transverse direction
Picture element provides 2 light source of the first display screen as expression, and including backlight (figure omits).Each rgb pixel is periodically shown
First picture 21 and the second picture 22.Second display screen 3 is adjacent to the side of first display screen 1, by opening or closing
The second display screen 3, making to show the projection light direction of first picture 21 or second picture 22, (i.e. its is each described
Rgb pixel) generate do not deviate or deviate.
Blue phase liquid crystal layer 4 is adjacent to the side of the second display screen 3, and the blue phase liquid crystal layer 4 has the light of an angle, θ
Axis 41, controlling the blue phase liquid crystal layer 4 by application voltage makes the projection light direction and the optical axis 41 of first picture 21
Vertically, or the projection light direction of control second picture 22 is parallel with the optical axis 41, respectively in the blue phase liquid crystal
The side of layer 4 shows first picture 21 and second picture 22.
Specifically, as shown in Fig. 2A and Fig. 3, when first display screen 1 shows first picture 21, described
Two display screens 3 are opened, and the projection light 23 of first display screen 2 does not deflect after the second display screen 3, make described first
The projection light direction of picture 21 is vertical with the optical axis 41.As shown in Fig. 2 B and Fig. 3, when first display screen 1 show it is described
When the second picture 22, the second display screen 3 is closed, and the projection light 23 of second picture 3 is after the second display screen 3
It is rotated by 90 °, keeps projection light direction parallel with the optical axis 41 of the blue phase liquid crystal layer 4, and generate along 41 side of optical axis
To birefringent light 42 (ne and no).
Please with reference to shown in Fig. 5, grating 5 is adjacent to the side of the blue phase liquid crystal layer 4, in the present embodiment, grating 5
Slit grating preferably with multiple interval blackstreaks.The rgb pixel is realized by controlling the blue phase liquid crystal layer 5
After offset, it is displayed on described in first picture 21 and second picture 22 process of the side of the blue phase liquid crystal layer 5
Grating 5 makes first picture 21 reach the left eye of viewer, and second picture 22 reaches the right eye of viewer, realizes color
Color 3D image.
Please with reference to shown in Fig. 4, the angle (θ) of the blue phase liquid crystal layer 4 is between 30-60 degree, preferably 45 degree.
The refractive index of the angle (Φ) of the birefringent light 42, the birefringent light (ne and no) is respectively 1-2, wherein
When the wavelength of second picture 22 is shorter, the birefringent light 42 is bigger, and the ratio of no/ne is smaller, thus
Second picture 22 is set to be displaced to same position.The thickness of the blue phase liquid crystal layer 4 in the present embodiment is between 3-100 microns
(um).When 4 thickness of blue phase liquid crystal layer is constant, ne is controlled by changing the voltage strength applied, makes the institute of different wave length
It states (the no and ne) ratio having the same of birefringent light 42 and obtains the angle Φ and remain unchanged, so as to control described second simultaneously
Picture 22 obtains identical offset.
In other words, the offset of each rgb pixel is realized by controlling the birefringent light 42 of blue phase liquid crystal layer 4, that is to say, that
Bore hole 3D display device 1 of the present invention shows that first picture 21 reaches the left eye of viewer in first time T1, at second
Between T2 show that the second picture 22 shifts (change apply voltage strength control ne) after blue phase liquid crystal layer 4, using light
Grid 5 reach the right eye of viewer, to realize colored 3D display, improve the resolution ratio (image of bore hole 3D display device 1 whereby
resolution).Therefore divided using the time that human eye can not almost be differentiated and spatially generate dislocation, produced by grating 5
Raw 3D image shows first picture 21 and second picture 22, and need not be by bore hole 3D display device 1 one of the invention
It is divided into two parts.
It should be noted that being also placed with multiple blue phase liquid crystal molecule (blue phase in the blue phase liquid crystal layer 5
Liquid crystal molecule) and each blue phase liquid crystal molecule optical axis 41 be single optical axis, by apply voltage make
Each blue phase liquid crystal molecule generates birefringent light 42.Specifically, when the second picture 22 of display and to each blue phase
Liquid crystal molecule can shift after applying voltage and (change refractive index), the right eye of viewer be reached using grating 5, to realize
3D display.
Since blue phase liquid crystal molecule is isotropism type (isotropic type).More specifically, when not applying electricity
When pressure, blue phase liquid crystal molecule has optical isotropy characteristic in two or three dimensions.Upon application of a voltage, blue phase liquid crystal
Molecule has birefringent characteristic (birefringence property) along a direction.Upon application of a voltage, blue phase liquid crystal
Molecule (blue phase liquid crystal molecule) has optically uniaxial characteristic (optical uniaxial
property).Therefore, with nematic liquid crystal molecules (nematic liquid crystal molecule), blue phase liquid crystal
Molecule transmissivity in the case where applying voltage has view angle dependency.On the other hand, because in isotropism liquid crystal molecule
There is no the initial orientation of optical anisotropy (optical anisotropic), so with nematic liquid crystal molecules difference, blue phase
Liquid crystal molecule can be along the direction orientation of electric field.
Please also refer to shown in Fig. 6, the present invention also provides a kind of naked eye 3D display methods, comprising the following steps: S10, mentions
