Embodiment
As shown in Figure 3 and Figure 5, a kind of bore hole 3D image displays, including：First display panel 1, includes multiple first
X and second direction Y array arrange that first pixel is to that should have left-eye image and eye image to pixel in the first direction respectively；
Second display panel 2, is arranged on first display panel 1, and includes multiple second pixels Y and the in a second direction respectively
One direction X array arrangement, including multiple pixels, the multiple second pixel include left eye pixel and right-eye pixel；Display light source
3；Liquid crystal lens array device 4, is face in the display surface of second display panel 2, and saturating including multiple cylinders
Mirror 41, the multiple cylindrical lens 41 is configured to along the direction of the arrangement states according to second display panel 2
It is in tilted layout, range of tilt angles is 30 °~45 °, wherein 45 ° of best results；And processor, the processor reception first
The signal of pixel, and control instruction is sent accordingly to control module, the control module control constitutes opening for second pixel
Open and close.
In horizontal bar arrangement, oblique lenticular lens systems are used to eliminate irregularity in brightness.The cylindrical axes of cylindrical lens
(central shaft) is inclined with angle, θ in the plane parallel to the display surface of the second display panel 2 from the Y direction in construction space
Tiltedly.When using oblique lenticular lens systems to eliminate irregularity in brightness, in the case where horizontal bar is arranged, in horizontal direction
Sub-picture element pitch is more than the sub-picture element pitch in vertical bar deployment scenarios.In other words, when the pixel pitch on shorter direction be Px,
And when the pixel pitch on longitudinal direction is Py (Py ＞ Px), in the case where vertical bar is arranged, the sub- picture in horizontal direction
Plain pitch is Px, but in the case where horizontal bar is arranged, the sub-picture element pitch in horizontal direction is Py.Therefore, post is added
The tiltangleθ of face lens, therefore, it is difficult to the anaglyph on separation of level direction.In addition, being allocated the adjacent son of identical quantity
Pixel R, G and B (Ri, Gi and Bi, i=1,2,3 ...) the unit pixel for combining to form colored display.For example, in inclination side
Sub-pixel (R2, G2 and B2) adjacent to each other combines to form unit pixel upwards.
Sub-pixel R, G and B of 1 pixel are constructed with 1 row and 1 arranged for interval arranged.The tiltangleθ of cylindrical lens now leads to
Cross θ=tan-1(Py/Px) obtain.In typical display panel, the depth-width ratio of 1 pixel is 1: 1, so as to establish Py=
3Px.Therefore, the tiltangleθ of cylindrical lens is 72.4 °.In the case, the refracting power in vertical direction (Y-direction) is more than
Refracting power in horizontal direction (X-direction), so that the separation degree of the anaglyph in vertical direction is more than horizontal direction.
In stereoscopic vision, the parallax in horizontal direction is important, it is therefore desirable to which tiltangleθ is 45 ° or smaller.Accordingly, it is considered to pass through
Distance in vertical direction between sub-pixel R, G and B of increase by 1 pixel of construction and the tiltangleθ for reducing cylindrical lens
Method.
As shown in figure 5, cylindrical lens 41 is preferably column prism arranged in parallel, and it is common with the second black matrix"
Bearing of trend is tilted relative to first direction X and second direction Y.Because the black matrix" of cylindrical lens 41 and second is relative to second
Direction Y is tilted, thus may be corresponded to above projection overlapping area adjacent on second direction Y different cylindrical lens 41 and
Second black matrix".In other words, the light that projection overlapping area adjacent on second direction Y is produced will all be not by surface
Or the outgoing of cylindrical lens 41 of the same side oblique upper, therefore both shooting angles can be made different.As it was previously stated, in a first direction
Several projection overlapping areas of the upper same rows of X can have identical light modulation amount to merge generation large viewing scope, and real
It is to be treated as same pixel to use on border.In other words, resolution ratio in a first direction on X is come compared with the quantity in projection overlapping area
Must be low.It can now be tilted by the above-mentioned black matrix" of cylindrical lens 41 and second and cause two neighboring projection weight on second direction Y
Repeatedly the irradiant dislocation in area and differential seat angle relation, the aobvious of overlapping area is projected by next column (next column on second direction Y)
Show that signal fills into previous column, and the pixel as same row is used, therefore the loss of resolution ratio on X in a first direction can be made up.
As it was previously stated, first pixel can produce two projection overlapping areas on second direction Y, so even the projection that two are arranged
Overlapping area is used as a row, and actually the resolution ratio on second direction Y can still maintain the first pixel of script in second direction Y
On quantity.
When having gap between the first display panel 1 and the second display panel 2, it is possible to produce light because of the elongation of light path
Cross-talk (crosstalk) phenomenon of signal in space so that the correctness of optical signal is affected.In the implementation shown in Fig. 7
In example, there is the first display panel 1 first black matrix" to be arranged between the first adjacent pixel；Second display panel 2 has the
Two black matrix"s are arranged between the second adjacent pixel.First black matrix" and the second black matrix" can preferably be made on processing procedure
The mode for making black matrix is formed.First black matrix" has the first width U1 on X in a first direction, and the second black matrix" is first
There is the second width U2 on the X of direction.Another second pixel has the second pixel wide W2 on X in a first direction.As the first width U1
And second width U2 sum total be more than the second pixel wide W2 when, two adjacent first pixels under different second pixels are produced
Raw light is to be not likely to produce cross talk phenomenon.If as shown in fig. 7, the first width U1 and the second width U2 sum total are more than the second picture
Plain width W2, when the light produced by two adjacent first pixels under different second pixels both passes through a top therein
During the second pixel, it can be influenceed respectively by the first black matrix" and the second black matrix" so that both exiting angle ranges
Overlapping is controlled, to alleviate cross talk phenomenon.Similarly, it on second direction Y, can also make similar setting, be showed with alleviating cross-talk
As.
The control module individually controls to constitute the opening and closing of the partial pixel of second pixel so that regulation and control are more
Plus it is fine, while saving the energy.
As shown in figure 8, light produced by projection overlapping area is projected after cylindrical lens floor, its light field is in a first direction on X
Width F can be represented with following formula, if wherein assuming that the second pixel wide W2 is negligible relative to F：Wherein, wherein：θ=tan-1[(6W1-2U1+U2)/2d],
As shown in figure 8, the first pixel is in having the first pixel wide W1 on first direction X, cylindrical lens 41 is in first party
There is prism width P, the second display panel 2 and cylindrical lens interlayer have the first space D on to X, the first display panel 1 and the
There is the second spacing d between two display panels 2；Wherein, width F of the light field in a first direction on X is preferably cylindrical lens 41 same
On one direction between 2 to 3 times of width, then U1, U2, W1, P, D and d relation preferably meet relational expression：2P*d<D(5W1-
2U1+U2)≦3P*d。
Herein under a design, the light that at least adjacent three cylindrical lenses 41 can be produced by single projection overlapping area irradiates
Arrive.Because at least one in the second black matrix" corresponding to adjacent three cylindrical lenses 41 can be corresponding with this projection overlapping area
First black matrix" has identical color, it is thus ensured that the light in this projection overlapping area at least can be by a cylindrical lens 41
Outgoing.
Further, the black matrix" is 1st/1st to five/6th of the first pixel and the second pixel wide.
The liquid crystal lens array device includes two parallel first substrates and second substrate, in the middle of two substrates
Liquid crystal layer and both sides first electrode and second electrode, vertical throwing of the first electrode on the surface of the second substrate
Shadow, has a lap with adjacent second electrode, and the lap has an overlap length, and the overlap length is 3~6 μ
m。

Upright projection of one first electrode on the surface of second substrate, second electrode adjacent with two partly overlaps (i.e. overlapping portion
Divide O1).And upright projection of each second electrode on the surface of first substrate, first electrode adjacent with two partly overlaps
(i.e. lap O2).
Consequently, it is possible to when apply between first electrode and second electrode liquid crystal molecule in an electric field, liquid crystal layer just by
Change its orientation to the influence of electric field so that the index distribution of liquid crystal layer is similar to solid lens.In detail, it is first
The normal direction for first defining first substrate and second substrate is vertical direction, and the bearing of trend of first substrate and second substrate is
Horizontal direction.In the case where applying electric field, the electric field between first substrate and second substrate is between lap O1 and O2
It is different with other regions.There is most strong vertical electric field between lap O1 and O2, and further away from lap O1
With O2, vertical electric field strength is weaker.Refractive index of the liquid crystal molecule under vertical electric field is defined as first refractive index, and in level electricity
Refractive index off field is defined as the second refractive index.Therefore between lap O1 and O2, liquid crystal molecule has first refractive index,
As away from lap O1 and O2, liquid crystal molecule changes into the second refractive index gradually.Consequently, it is possible to via the first above-mentioned electricity
Pole and the arrangement mode of second electrode, overall liquid crystal layer can produce the index distribution similar in appearance to solid lens.
