Embodiment 2
The present embodiment proposes a kind of 3D display screen alignment method, aligns system using the above-mentioned 3D display screen of above-described embodiment 1
System, executing subject are to align processing module, the above-mentioned chromaticity coordinates measured for obtaining above-mentioned chromaticity coordinates measurement module, and work as root
When determining that above-mentioned 3D display screen needs to align according to above-mentioned chromaticity coordinates, alignment operation is carried out to above-mentioned 3D display screen.
Alignment method process shown in Figure 4, the 3D display screen alignment method that the present embodiment proposes, including in detail below
Step:
Pixel in the domain of left eye viewing zone when step 400, the left eye viewing zone domain for obtaining 3D display screen 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 comprehensive 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 include the following steps (1) to step (4):
(1) whether the first chromaticity coordinates that judgement is got meets preset first chromaticity coordinates threshold value, if it is executes step
Suddenly (2) then follow the steps (4) if not；
(2) continue whether the second chromaticity coordinates that judgement is got meets preset second chromaticity coordinates threshold value, if it is hold
Row step (3), thens follow the steps (4) if not；
(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 screen.
In above-mentioned steps (1), the first color is if it is red, then the first chromaticity coordinates of corresponding standard is set as
(0.670,0.330), can preset the first chromaticity coordinates threshold value is (0.670 ± 0.015,0.330 ± 0.015), thus right
Whether the color of pixel is that red is determined in the domain of left eye viewing zone.When the chromaticity coordinates of pixel falls into the first chromaticity coordinates threshold
When the range that value is marked, it is determined that red is shown in the pixel.
Correspondingly, the second color is if it is green in above-mentioned steps (2), then the second chromaticity coordinates can be set to
(0.210,0.710), then presetting the second chromaticity coordinates threshold value is (0.210 ± 0.015,0.710 ± 0.015), thus to the right side
Whether the color of pixel is that green is determined in eye viewing areas.Judgment mode and the above-mentioned determination pixel display color
It whether is that red process is similar, which is not described herein again.
After through the above steps 402 get comprehensive chromaticity coordinates, 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 tilts, alignment operation is carried out to above-mentioned 3D display screen.
In the related technology, since viewer is not that head is fixed on same position always, such as slight head movement exists
Very common phenomenon, will lead to the image information seen has inclined line of demarcation, and there are also go here and there for the 3D display screen after leading to contraposition
Defect is disturbed, the viewing visual angle of 3D display screen is greatly reduced.Therefore, it is lacked in order to ensure the 3D display screen after contraposition does not occur crosstalk
It falls into, above-mentioned steps 404 include 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 column 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 screen；
(3) the third chromaticity coordinates that respective column chromaticity coordinates threshold value is unsatisfactory in each column chromaticity coordinates is determined；
(4) above-mentioned third chromaticity 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) tilt angle in above-mentioned line of demarcation is calculated；
(6) tilt angle in the above-mentioned line of demarcation being calculated when basis determines above-mentioned left eye viewing zone domain and above-mentioned right eye
When the line of demarcation inclination of viewing areas, alignment operation is carried out to above-mentioned 3D display screen.
