In order to prevent during contraposition the Grating Film local buckling of 3D display screens or deformation band to come for example, bubble is not Good influence, the size of above-mentioned bit cell is not less than the size of above-mentioned 3D display screens.It is flat after Grating Film absorption so as to ensure Whole property, prevents that Grating Film understands local buckling during aligning or deformation band carrys out the harmful effect of such as bubble.
Embodiment 2
The present embodiment proposes a kind of 3D display screens alignment method, and system is aligned using the above-mentioned 3D display screens of above-described embodiment 1 System, executive agent is contraposition processing module, for obtaining the above-mentioned chromaticity coordinates that above-mentioned chromaticity coordinates measurement module is measured, and works as root When determining that above-mentioned 3D display screens need contraposition according to above-mentioned chromaticity coordinates, alignment operation is carried out to above-mentioned 3D display screens.
Alignment method flow shown in Figure 4, the 3D display screen alignment methods that the present embodiment is proposed, including in detail below Step:
Pixel in the domain of left eye viewing zone when step 400, the left eye viewing zone domain of acquisition 3D display screens show the first color The first chromaticity coordinates and right eye viewing zone domain pixel in the domain of right eye viewing zone when showing the second color the second chromaticity coordinates.
Wherein, there is line of demarcation between above-mentioned left eye viewing zone domain and above-mentioned right eye viewing zone domain.Such as:The line of demarcation is just It is the straight line O1O2 in the synthesis chromaticity coordinates P3 shown in Fig. 2 and Fig. 3.
When contraposition processing module shows the first color by the first colorimeter and the second colorimeter acquisition left eye viewing zone domain Picture in the domain of right eye viewing zone when the first chromaticity coordinates of pixel and right eye viewing zone domain show the second color in the domain of left eye viewing zone Second chromaticity coordinates of vegetarian refreshments.
Step 402, when determining picture in above-mentioned left eye viewing zone domain according to the first chromaticity coordinates for getting and the second chromaticity coordinates When vegetarian refreshments shows that pixel shows the second color in the first color and above-mentioned right eye viewing zone domain, comprehensive chromaticity coordinates is obtained;
Specifically, above-mentioned steps 402 comprise the following steps (1) to step (4):
(1) judge whether the first chromaticity coordinates got meets default first chromaticity coordinates threshold value, if it is perform step Suddenly (2), if otherwise performing step (4);
(2) continue to judge whether the second chromaticity coordinates got meets default second chromaticity coordinates threshold value, if it is hold Row step (3), if otherwise performing step (4);
(3) determine that pixel shows pixel in the first color and above-mentioned right eye viewing zone domain in above-mentioned left eye viewing zone domain Point shows the second color, and obtains comprehensive chromaticity coordinates;
(4) alignment operation is carried out to 3D display screens.
In above-mentioned steps (1), the first color is if red, then the first chromaticity coordinates of corresponding standard is set to (0.670,0.330), can preset the first chromaticity coordinates threshold value for (0.670 ± 0.015,0.330 ± 0.015) so that right Whether the color of pixel is that red is judged in the domain of left eye viewing zone.When the chromaticity coordinates of pixel falls into the first chromaticity coordinates threshold During the scope that value is marked, it is determined that red is shown in the pixel.
Accordingly, in above-mentioned steps (2), the second color is if green, then the second chromaticity coordinates can be set to (0.210,0.710), then preset the second chromaticity coordinates threshold value for (0.210 ± 0.015,0.710 ± 0.015) so as to the right side Whether the color of pixel is that green is judged in eye viewing areas.Judgment mode and the above-mentioned determination pixel display color Whether it is that red process is similar, repeats no more here.
After comprehensive chromaticity coordinates is got by above-mentioned steps 402, following steps 404 can be continued through left eye is watched Whether the line of demarcation in region and above-mentioned right eye viewing zone domain, which tilts, is judged.
Step 404, when determining above-mentioned left eye viewing zone domain and above-mentioned right eye viewing zone domain according to above-mentioned comprehensive chromaticity coordinates When line of demarcation is tilted, alignment operation is carried out to above-mentioned 3D display screens.
In correlation technique, because beholder is not that head is fixed on into same position all the time, such as slight head movement exists Very common phenomenon, can cause the image information seen to have inclined line of demarcation, cause the 3D display screens after contraposition to also have string Defect is disturbed, the viewing visual angle of 3D display screens is greatly reduced.Therefore, lack in order to ensure the 3D display screens after contraposition occur without crosstalk Fall into, above-mentioned steps 404 comprise the following steps (1) to step (6):
(1) the chromaticity coordinates component color coordinates matrix for meeting default chromaticity coordinates interval is obtained out of above-mentioned comprehensive chromaticity coordinates;
(2) judge that whether each row chromaticity coordinates meets respective column chromaticity coordinates threshold value in above-mentioned chromaticity coordinates matrix, if it is holds Row step (3), if otherwise carrying out alignment operation to above-mentioned 3D display screens;
(3) trichromatic coordinates that respective column chromaticity coordinates threshold value is unsatisfactory in each row chromaticity coordinates is determined;
(4) above-mentioned trichromatic coordinates is subjected to linear fit, obtains above-mentioned left eye viewing zone domain and above-mentioned right eye viewing zone The line of demarcation in domain;
(5) angle of inclination in above-mentioned line of demarcation is calculated;
