Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of patent protection of the present invention.
According to an aspect of the present invention, a kind of holographic display floater is embodiments provided.As shown in figure 1, institute
Stating holographic display floater 100 includes：Multiple pixels 101 of array arrangement and the light emission side for being arranged in the plurality of pixel 101
Phase-plate 102；And stop member 103, the stop member 103 is arranged in the light path between pixel 101 and phase-plate 102
Edge, for stopping by the marginal portion of the light beam 104 of the diffraction of the pixel 101.
In embodiments of the present invention, using the stop member of arrangement above, husband thinkling sound in small-sized pixel is solved well
With light beam cross-interference issue caused by the institute of fraunhofer-diffraction angle.Therefore, using the configuration of the embodiment of the present invention, can not only obtain clearly
Pixel edge, eliminates color cross-talk and gray scale crosstalk, additionally it is possible to provide accurate image depth, improves the vision of holographic display
Effect.
As shown in figure 1, the pixel 101 can be the pixel in display panels, it utilizes liquid crystal 105 to control each

Keep off by the marginal portion of the light beam of pixel diffraction, it is to avoid inject the corresponding phase-plate of neighbor in the marginal portion.
For given pixel, Fraunhofer diffraction angle θ=1.22 λ/w.For less angle, θ, θ/2 ≈
tgθ/2=a/d.It is possible thereby to obtain the width a=0.61 λ d/w of the stop member 103.
From above-mentioned relation, with the increase apart from d, the width a of the stop member 103 also accordingly increases.
For given pixel wide w, too big stop member 103 may can stop on the contrary the close optical axis of the light beam 104
Part, so as to lose light intensity.Therefore, should be by the width a of the stop member 103（Or, the stop member 103 with
The distance between the pixel 101 d）It is limited in appropriate scope.Assume between adjacent two pixels 101 at intervals of p,
Then the width a of stop member 103 should be less than p.Thus can obtain, 0.61 λ d/w≤p, i.e., described stop member 103 and the picture

Constitute（As shown in Figure 3 a）.The phase-plate of one can include multiple effective districts, and the plurality of effective district corresponds respectively to described
Multiple pixels.The phase-plate of one can be directly arranged at the light emission side of the plurality of pixel, so as to control from described many
The light beam of individual pixel.In the context of the disclosure, " light path between pixel and phase-plate " refer to single pixel and with institute
State the light path between the corresponding sub- phase-plate/effective district of pixel.
Similarly, it is also possible to which the phase-plate of the phase-plate of one or many sub- phase-plate compositions is arranged in into first base
The stop member is arranged in the first substrate in the face of the plurality of pixel by backboard from the surface of the plurality of pixel
Surface.In this case, it is possible to make the stop member using the black matrix technique in such as display panels.Cause
This, stop member can have multiple openings, the plurality of opening and the plurality of effective district or a pair of many sub- phase-plates 1
Should.
Alternatively, the phase-plate is diffraction grating.
Using the diffraction grating with different parameters, can be by the light beam regulation of pixel to desired direction.By
This, as shown in Figure 3 a, phase-plate 102 can control angle of diffraction β of the emergent ray of Jing phase-plates 102.Wherein, the above-mentioned angle of diffraction
Degree β is the angle between the emergent light of phase-plate 102 and the direction of propagation of incident light.
It should be noted that because above-mentioned multiple phase-plates 102 are used to carry out incident light diffraction, therefore the phase-plate
102 can adopt phase grating, i.e. diffraction grating.On this basis, in order to improve the utilization rate of light, can be with selective transmission
Grating is used as above-mentioned phase-plate 102.In the case, due to light transmission grating projection and sunk part phase place not
Together, therefore, it is possible to so that light occurs diffraction after the transmission grating.
Specifically, when the phase-plate 102 is transmission grating, the transmission grating can be single-order grating as shown in Figure 3 b
Or multistage grating as shown in Figure 3 c.In the case, the diffraction angle beta of transmission grating m order diffractions ripple only by screen periods P,
The wavelength X and incident angle β of incidence wave0Determine, i.e. sin β-sin β0=m λ/P (m=0, ± 1, ± 2 ...).Therefore, in incidence
In the case of the wavelength X identical of light, the cycle P for adjusting transmission grating can be passed through, reach the purpose for adjusting diffraction angle beta.

Display floater shows the multiple images with the different depth of field, so as to provide the picture with multiple depth of field.
Specifically, as shown in Fig. 3 a and Fig. 5, the different pixel 101 of three adjacent colors can be counted as pixel 01
Three sub-pixels, from the angle of diffraction β all same of the light beam of phase-plate 102 corresponding with them outgoing.Similarly, with pixel
Angle of diffraction β of the light beam of three sub-pixel 101' corresponding phase-plate 102 outgoing of 01' ' all same, and β ≠ β '.It is some
Individual pixel 01 and pixel 01' constitute the first pixel groups 10.From the reverse extending line of the light beam of pixel 01 and from pixel 01'
