Embodiment
The explanation of following embodiment is refer to the attached drawing, can be to the specific embodiment implemented to the example present invention.
It refer to shown in Fig. 2, the embodiment of the present invention provides a kind of LCDs mura compensation methodes, LCDs bag
Splicing regions and non-splicing regions are included, LCDs mura compensation methodes include：
The mura measurement offset datas of the multiple predetermined GTGs of LCDs gone out by measurement camera measurement are obtained, according to institute
The mura measurement offset datas for stating predetermined GTG obtain the mura offset datas of non-each GTG of splicing regions；
The mura measurement offset datas of the multiple predetermined rgb values of LCDs gone out by measurement camera measurement are obtained, and are carried
The mura measurement offset datas of multiple predetermined rgb values of splicing regions are taken out, are measured according to the mura of the multiple predetermined rgb value
Offset data obtains the mura offset datas of each rgb value in splice region；
Mura compensation is carried out to the display image of non-splicing regions using the mura offset datas of each GTG, using institute
The mura offset datas for stating each rgb value of splicing regions carry out mura compensation to the display image of splicing regions.
The mura compensation methodes of the present embodiment, the splicing situation on 8k LCDs is taken into full account, to splicing regions
Specially treated is carried out, is compensated using three color RGB mura offset datas, compensation is more accurate, eliminates splicing regions
Mura phenomenons, make splicing regions transitions smooth, display is finer and smoother, improves the quality of LCDs.
Specifically, the multiple predetermined GTGs of LCDs are gone out by measuring camera measurement first to reduce memory data output
Mura measurement offset data, such as GTG 25, GTG 60 and GTG 225 mura measurement offset data, other GTGs
The mura measurements offset data for the predetermined GTG that mura offset datas pass through storage obtains, for example with linear interpolation mode, root
The mura offset datas of GTG 50 are obtained according to GTG 25 and GTG 60.
Similarly, the mura for the multiple predetermined rgb values of LCDs being gone out by measuring camera measurement measures offset data, can
With understanding, GTG is formed by tri- component combinations of R, G, B, for example, GTG be 60 when, tri- components of R, G, B all be 60；
And when measuring RGB mura data, if R is 60, G, B are 0, then measure corresponding R mura offset datas；If G
For 60, R, B are 0, then measure corresponding to G mura offset datas；If B is 60, R, G are 0, then measure corresponding
B mura offset datas.
Because the mura measurement offset datas that measurement camera measures the multiple predetermined rgb values come are to be directed to whole viewing area
, the present embodiment also needs to extract the mura measurements offset data of multiple predetermined rgb values of splicing regions.It is foregoing " to spell
Connect region " be greater than on display screen because CF light shields splicing caused by actual splicing regions so that compensation more comprehensively, exhaustive.So
The mura offset datas of the offset data acquisition each rgb value in splice region are measured according to the mura of the multiple predetermined rgb value afterwards, such as
Using linear interpolation mode.
Again as shown in figure 3, being its corresponding linear interpolation formula below：
I.e.：Y=a × y1+b × y2；Wherein, a=(x1-x)/(x1-x0), b=(x-x0)/(x1-x0).Wherein, x1, x0
GTG corresponding to adjacent GTG or predetermined rgb value is represented, y1, y0 are that corresponding mura measures the offset data (mura of GTG
Measure offset data or the mura measurements offset data of rgb value), x represents GTG corresponding to each GTG or each rgb value.
As it was previously stated, when being calculated by above-mentioned linear interpolation formula, RGB is that the data of form are different with GTG, GTG
Mura measurements offset data be exactly that tri- components of RGB use same data, it is exactly RGB that RGB mura, which measures offset data,
Three component data differences.
After calculating the mura offset datas of GTG and RGB mura offset datas, you can pointedly compensate：
The mura that the mura offset datas of each GTG are used for non-splicing regions display image is compensated, by each rgb value
The mura that mura offset datas are used for splicing regions display image is compensated.
Because splicing regions have splicing mura, the present embodiment uses the mura offset datas of rgb value to compensate to it,
And non-splicing regions are compensated using the mura offset datas of GTG；If to whole viewing area using RGB's
Mura offset datas compensate, then offset data amount can be quite big, and the capacity for causing flash is increased.
Further, the mura measurement compensation numbers of the multiple predetermined GTGs of the LCDs gone out by measurement camera measurement are obtained
According to when, also compressed with the interregional of M × N (M, N are the integer more than 1, such as 8 × 8) pixel every doing, by the more of splicing regions
The mura measurements offset data of individual predetermined GTG is extracted and stored in memory.As a kind of example, multiple predetermined ashes
Rank can be GTG 25, GTG 60, GTG 225.
When display image is sent, first read in advance from memory splicing regions multiple predetermined GTGs (such as
GTG 25, GTG 60, GTG 225) mura measurement offset datas, then measured with the mura of multiple predetermined GTGs of splicing regions
Offset data carries out the mura offset datas that linear interpolation obtains each GTG of splicing regions.For example, according to GTG 25, GTG 60,
GTG 225 and GTG 0, the measurement offset data of GTG 255 carry out the mura offset datas that linear interpolation obtains each GTG.Can be with
Understand, GTG 0 and GTG 255 are minimum value and maximum respectively, and its mura measurements offset data is fixed, and GTG
225, GTG 60, the mura measurements offset data of GTG 25 is what is come out by measuring camera measurement.
Linear interpolation formula as shown in Figure 3 is as follows：
I.e.：Y=a × y1+b × y2；Wherein, a=(x1-x)/(x1-x0), b=(x-x0)/(x1-x0).Wherein, x1, x0
Adjacent predetermined GTG is represented, y1, y0 are corresponding measurement mura offset datas, and x represents each GTG.
It can be obtained from above：As long as non-linearly changing a, b value can realizes non-linear interpolation.
Splice mura because existing, a, b can be stored in memory respectively as two parts of coefficients, and portion is splicing regions
Mura penalty coefficient, portion are normal mura coefficients.
After a, b are stored in into memory, the mura offset datas using each GTG of the splicing regions show to splicing regions
Diagram picture carries out mura compensation, viewing splicing mura demura effects.If splicing regions still can also be seen by human eye
Mura be present, then foregoing two parts of coefficients (a, b) of non-linear trimming memory, demura effects are watched when adjusting, until mura
Disappear.Yet further, because the red resistance in CF light shield splicing regions, green resistor width, blue resistor width differ
Sample (compared with being not splicing regions), during corresponding color resistor width difference, in same grayscale, the light that passes through also not phase
Together, so that colour cast can be caused.Therefore, the present embodiment is also adjusted to the colour cast of LCDs.
If display panel has the splicing of CF light shields, display panel is divided into two regions, joined with reference to different white balances
Examine form and white balance is adjusted to described two regions.Specifically, for CF light shield splicing regions, joined by changing the first white balance
The white balance code examined in form carries out blank level adjustment, to offset because color resistor width difference caused by the splicing of CF light shields causes
Colour cast.For non-CF light shields splicing regions, then put down in vain by changing the white balance code in the second white balance reference table
Weighing apparatus adjustment.
By described above, the beneficial effect of the embodiment of the present invention is：Take into full account on 8k LCDs
Splicing situation, to splicing regions carry out specially treated, compensated using three color RGB mura offset datas, compensation it is more smart
Really, the mura phenomenons of splicing regions are eliminated, make splicing regions transitions smooth, display is finer and smoother, improves LCDs
Quality.
Above disclosure is only preferred embodiment of present invention, can not limit the right model of the present invention with this certainly
Enclose, therefore the equivalent variations made according to the claims in the present invention, still belong to the scope that the present invention is covered.
