Specific embodiment
Below in conjunction with accompanying drawing in the embodiment of the present invention, to the embodiment of the present invention in technical scheme carry out clear, complete
Ground description, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiment.Generally exist
The component of the embodiment of the present invention described and illustrated in accompanying drawing can be arranged and be designed with a variety of configurations herein.Cause
This, is not intended to limit claimed invention to the detailed description of the embodiments of the invention for providing in the accompanying drawings below
Scope, but it is merely representative of the selected embodiment of the present invention.Embodiments of the invention are based on, those skilled in the art are not doing
The every other embodiment obtained on the premise of going out creative work, belongs to the scope of protection of the invention.
Occur in that multiple 3D display devices in correlation technique, such as divided from the tilt condition of 3D display modules, can be with
It is divided into tiltedly row and in line two kinds.In current techniques, whether tiltedly arrange or in line 3D display devices, using hereinbefore step
The process of I-IV is processed.
As shown in Fig. 2 be a kind of lens pillar film 3D module schematic diagrams of oblique row, at two-dimensional Cartesian system (X, Y)
In, lens pillar film 111 forms angle of the inclination angle for β with 2D display screens 101 in X-direction, and β is Design Theory value herein.Due to
Many fabrication errors, actually lens pillar film 111 are β 1, β 1 and β with 2D display screens 101 in the angle that X-direction is formed
Compare either large or small (i.e. actual value has gap with theoretical value)；And lens pillar film 111 may have certain displacement in the X direction
Amount dx (dx is the error of lens pillar film 111 and theoretical position).In certain limit, the error that either dx and β-β 1 bring,
Or the fabrication error of raster pitch p can be fitted (I～III) by the flow process shown in Fig. 1 and red green correction (IV)
Actual parameter value is obtained, and on this basis by way of row's figure so as to obtaining preferable 3D effect.
Fig. 3 is the disparity barrier 3D module schematic diagrams of oblique row, and the spacing between any two of which adjacent slots is p, one
Determine in scope because of the difference caused by fabrication error between Design Theory angle of inclination beta and the angle of inclination beta 1 after actual laminating and parallax
Side-play amount dx that barrier 3D light-splitting devices 112 are fitted in X-direction with 2D display screens 101, fabrication error of slit separation p etc. because
Element, it is also possible to be corrected by the flow process shown in figure one.
Above-mentioned correcting process (step I-IV) is only suitable for tiltedly row 3D modules.The bearing calibration is only to tiltedly row's 3D moulds
Group is suitable for, and is primarily due to (structure as shown in Figure 2) when lens pillar film 111 is inclined, according to grating edge cuts when inclining
Sub-pixel such as 1/5,1/6 grade weighting readjustment entire row nomography of size, edge can be smoothed.To in line mould
Group, if dx is slightly displaced from and angle does not have error (in line lens pillar film 111 inclines 90 degree, i.e. lens pillar
Film 111 is parallel to the Y-direction in figure four), at this moment While it can be seen that 3D, but viewing location is not in screen center, i.e. center
To the left or to the right；And if angle has error, necessarily cause grating pitch P in the horizontal direction to become p/sin (β) (such as
Fig. 2, β are optical grating axial and horizontal direction angle, p/sin (β)=p when β=90 degree).Such as Fig. 4, in line grating must be covered
Even number pixel, that is, 6 times for sub-pixel width of horizontal direction pitch P when designing, 12 times, 18 times etc., and p/sin (β) is no longer
Picture will be caused when being these multiples to show abnormal, (picture will be shown as discontinuous, bar as red green synthesising picture normally can not show
The phenomenons such as stricture of vagina), crosstalk is also increased dramatically therewith, so the impact of angular error is bigger, it is necessary to preferential guarantee, and shown in Fig. 1
Flow process (step I-IV) laminating when cannot ensure the precision of angle and the side-play amount in x directions, so being not suitable in line.
Existing 3D display modules, are entirely almost oblique row's mode in large-sized advertisement machine field.At undersized
People's consumer product area such as mobile phone, in flat board application, a variety of technical schemes in addition to oblique 3D modules of row's mode, using regarding
Difference barrier-type and lens coating pad pasting also have much in line 3D modules.
Fig. 4 is without the in line schematic diagram of rib grating 3D modules.Grating extension direction in the 3D modules, without rib grating 111
(length direction) aa ' is vertical with the same color sub-pixels direction of 2D display screens 101.Two-dimentional Descartes as shown in Fig. 4
In coordinate system (X, Y), direction aa ' is parallel with Y direction for grating extension, and same color sub-pixels such as R, G, B and X-axis are flat
OK.Figure five is the in line schematic diagram of disparity barrier 3D modules, in the 3D modules, the extension direction of liquid crystal slit or fixed slit
Vertical with the same color sub-pixels direction of 2D display screens 101.In the two-dimensional Cartesian system shown in, liquid crystal slit
Or the extension direction of fixed slit is parallel with Y direction, and same color sub-pixels such as R, G, B is parallel with X-axis.To similar
This in line 3D modules, Anawgy accuracy requirement are very high, and existing equipment and technological process are difficult to meet.The reason for because of row's figure,
Extension direction and same color sub-pixels direction out of plumb, i.e. 3D light-splitting devices 111 or 112 and 2D when grating or slit
Display screen 101 have rotated certain angle when fitting so that slit or grating extension direction aa ' are no longer parallel with Y-axis.Or
During laminating X-direction exist larger bit errors (it is generally acknowledged that>The error of more than 10um is larger bit errors) when, figure
Flow process shown in 1 cannot be suitable for, and therefore module is also watched less than good 3D effect.
For above-mentioned due to bit errors excessive, so as to the situation for causing 3D display devices normally cannot show.The application
A kind of corresponding manufacture method of bore hole 3D display device is provided, as shown in Figure 10, is comprised the steps：
S1001, for the purpose of being overlapped 3D device layers and 2D display screen layers, 3D device layers and 2D display screen layers is entered
The thick para-position of row；
S1002, is coated with liquid optical cement in 2D display screens layer towards the side of 3D device layers, to form liquid optical cement
Layer；
3D device layers and 2D display screens layer are carried out eclipsed form laminating by liquid optical cement layer, to form flat board by S1003
The 3D display screens of shape, 3D display screens include 3D device layers, liquid optical cement layer and the 2D display screen layers that order is stacked；
3D device layers and 2D display screens layer, by the way of right and left eyes image calibration, are carried out exactitude position by S1004；
S1005, to exactitude position after 3D device layers and 2D display screens carry out ultra-violet curing.
In step S1001, need for 3D device layers and 2D display screens layer to carry out thick para-position, during thick para-position and need not use
Extra alignment mark, this two-layer correspondingly can be gone up substantially.As 3D device layers and 2D display screens layer are usually size, shape
Shape (typically rectangle) all same plane, therefore can adopt the edge at the edge of 3D device layers and 2D display screen layers
The thick para-position in step S1001 is carried out to its mode.It is, of course, also possible to be that alignment mark is set in the corner of the two, such as
Mark can be respectively provided with the upper left corner of 3D device layers, the upper left corner in the upper right corner and 2D display screen layers, the upper right corner, in para-position,
The two marks can in para-position can (3D device layers and 2D display screens layer be transparent, therefore can be by this kind of mode
Carry out para-position).
Para-position in step S1001, is only that the position of the two can be corresponded to, when general operation, can make
With crosshead, the now thick para-position in step S1001 is to enable the two to essentially coincide (now 3D device layers and 2D display screens
Layer is not touched together).
In step S1002, the side coating liquid optical cement towards 3D device layers in 2D display screens layer is needed, to form liquid
State optical cement layer.It should be noted that liquid optical cement layer can be coated directly onto on 3D device layers, 2D can also be just coated on
Display screen layer, but need ensure be liquid optical cement layer be between 3D device layers and 2D display screen layers, in order to hold
Row step S1003.
In step S1003,3D device layers and 2D display screens layer are carried out by eclipsed form laminating by liquid optical cement layer, now
3D device layers and 2D display screens layer pass through liquid optical cement layer joint.But as time of contact is not long, do not carry out ultraviolet yet
Solidification, therefore now liquid optical cement layer paste and insecure.Further, in step S1004, right and left eyes image can be adopted
3D device layers and 2D display screens layer are carried out exactitude position by the mode of calibration.Exactitude position refers to aobvious to 3D device layers and 2D
The relative position of display screen layer carries out high-precision fine setting.When the foundation of high precision fine tuning is broadcasting pictures, (left eye is imaged left eye
Head) whether the image that receives meets expection, and/or whether the image that right eye (right eye photographic head) is received meets expection, such as
Really incongruent, then the relative position of 3D device layers and 2D display screen layers should be adjusted, until left eye (left eye shooting
Head) whether the image that receives meet expection, and/or the image that receives of right eye (right eye photographic head) meet expected till.
Afterwards, after the exactitude position of step S1004 terminates, just can be with execution step S1005, using the side of ultra-violet curing
3D device layers and 2D display screens are firmly fixed by formula.
Above-mentioned steps are executed for convenience, it is possible to use corresponding device can such as use upper vacuum aiding in executing
Absorption platform and lower vacuum absorbing platform are carrying upper vacuum absorbing platform or lower vacuum absorbing platform respectively.Now, step
S1001 includes：
3D device layers and 2D display screen layers are separately positioned on upper vacuum absorbing platform and lower vacuum absorbing platform；Upper true
Empty absorption platform and lower vacuum absorbing platform are in tabular, and are parallel to each other, and vertically overlap；
Vertically moved by driving upper vacuum absorbing platform or lower vacuum absorbing platform, make vacuum absorbing platform
Close to each other with lower vacuum absorbing platform, 3D device layers and 2D display screens layer are carried out thick para-position.
Similar, in other steps, when needing mobile 3 D device layer and 2D display screen layers, it is also possible to by driving upper vacuum
(upper vacuum absorbing platform and lower vacuum absorbing platform could be arranged to motor to complete for absorption platform and lower vacuum absorbing platform
The form being driven).
Below, a kind of making side of bore hole 3D display device provided herein is illustrated with a specific example

The image that eye/left eye photographic head is received only has left eye picture, the image that right eye/right eye photographic head is received to there was only right eye figure
Piece).
2 ', point solidification, after right and left eyes image calibration terminates, in four corners of 3D display screens 1000, i.e. ultra-violet curing
Pointing out (this four corners are generally invalid viewing area) carries out the solidification of ultraviolet point, to prevent upper and lower vacuum abutted platform U10, D10
During vacuum breaker there is relative displacement with 3D devices 1100 in 2D display screens 1010.After the solidification of ultraviolet point terminates, then to 3D devices
1100 carry out vacuum breaker process.
(IV), after upper and lower vacuum absorbing platform U10, D10 vacuum breaker, the 3D display screens 1000 that post are removed and is carried out
Comprehensive ultra-violet curing, reaching makes 1020 completely crued purpose of liquid optical cement.Here the set direction of ultra-violet curing is from compared with appearance
Side easily through UV light is irradiated.
Upper and lower vacuum absorbing platform U10, D10 in the embodiment preferably has the property that：(1), transparent material is used
Matter：For lower vacuum absorbing platform D10, preferable transmitance is unlikely to lose too many backlight illumination；For upper vacuum is inhaled
For attached platform U10, preferable transmitance enables the display letter that dual camera L and R are captured on 3D display screens through the platform
Breath；(2), plane displacement：In the three Cartesian coordinates (X, Y, Z) shown in Fig. 7, upper and lower vacuum absorbing platform U10,
At least one platform of D10 (preferably going up vacuum absorbing platform U10) can be distributed to enter with Y-direction in X/Y plane along the X direction
Row micro translation (within ± 100um), to drive 3D device layers and 2D display screens carry out relative translation；(3), put down

Maximum angle (being represented with spending) as β=2* δ Y/ δ X, be usually no more than 2 °.
Below the process of above-mentioned steps III is described in detail.
The process of step III mainly includes two contents, and first is 3D device layers and 2D display screen horizontal rotation types
Relative movement, second be 3D device layers and 2D display screen horizontal translations relative movement.Therefore, reality is being carried out using equipment
When operation, need to carry out three judgements successively to determine again specifically to adjust content
First judges it is to judge that whether the picture captured by left eye photographic head only has left eye picture, or judge that right eye is taken the photograph
As whether the picture captured by head only has right eye picture；
If the judgment is No, then execution step III (i.e. adjustment 3D device layers and 2D display screen layers relative position)；If
It is judged as YES, then can skips the process of the relative position of adjustment 3D device layers and 2D display screen layers, directly carry out ultraviolet solid point
Change.
In execution step III, should judge whether first to need to carry out revolving adjustment, that is, judge left eye photographic head
In the picture for being captured, whether the boundary line of left eye picture and right eye picture is to incline, or judge that right eye photographic head is caught
To picture in the boundary line of left eye picture and right eye picture be whether to incline；Inclination herein refers to left eye picture and the right side
Whether the boundary line of eye pattern piece is parallel with Y-axis, parallel with Y-axis, does not incline, conversely, being then to incline.
If inclining, then 3D device layers and 2D display screen layers are rotated against, until left eye photographic head is caught
To picture in the boundary line of left eye picture and right eye picture no longer incline (the i.e. boundary line and Y of left eye picture and right eye picture
Axle is parallel) till.Afterwards, if 3D device layers and 2D display screens layer are carried out left and right translation by necessity again again, until left eye is imaged
Whether the picture that captured of head only has left eye picture, or whether the picture that captured of right eye photographic head only has the right eye picture to be
Only.
If not incline, then 3D device layers and 2D display screens layer can be carried out relative translation in X direction directly, until
Whether the picture captured by left eye photographic head only has left eye picture, or whether the picture captured by right eye photographic head is only right
Till eye pattern piece.
Whether the above-mentioned boundary line for first determining whether left eye picture and right eye picture is inclined mainly it is considered that after rotation is adjusted
The position of boundary line can be changed, if first translational adjustment, then rotate regulation, then after rotation is adjusted, may be there is still a need for carrying out
Translational adjustment, then cause the waste of step.
Certainly, during concrete operations, corresponding mode can be selected to be adjusted with foundation particular situation.As shown in figure 9, showing
Several situations being likely encountered when step III is adjusted are gone out.
