When to judge that a region or multiple regions in the display image being subtracted have without exception bright for microcontroller component 199
Band, can be shown in via display component 197 display image in abnormal bright band brightness value (i.e. the brightness value of compensating basin) and
The brightness value (i.e. the standard values of standard regions) in other regions not comprising abnormal bright band.For example, the brightness value of abnormal bright band
Brightness value for 100 and other regions is 128 bits.Then, microcontroller component 199 is according to the brightness value and exception in other regions
The brightness value of bright band, calculates the offset of abnormal bright band, makes the brightness value of abnormal bright band close to the brightness in other regions whereby
Value is even identical with the brightness value in other regions.It is subsequent, according to different MURA types, with specific image compensation method
The MURA of compensation display image, as described below.
Refering to Fig. 3 and Fig. 4, the MURA type (gradual offset) of the first kind: for the positive perspective images of display panel 120
The side perspective images of zero defect and display panel 120, which are detected, one or more MURA.Microcontroller component 199 can analyze side view
The MURA of angle image, and the offset for corresponding to compensating basin is obtained, as shown in step S110.
Compensating basin be side perspective images abnormal bright band, and correspond to multiple arrays compensating unit, even it is multiple simultaneously
The compensation row of row.For example, in the display image of right side perspective, left side of the standard position in display image, compensation
Right side of the position in display image, the adjacent compensating basin in standard regions.Right margin court of the brightness value of compensating basin from display image
The adjoiner of standard regions and compensating basin gradually brightens or gradually dimmed (gradually brightening from right to left or gradually dimmed).Microcontroller
Component 199 analyzes the brightness value of compensating basin, and obtains the offset of compensating basin, such as from the right margin of display image towards standard regions and
The adjoiner of compensating basin is gradually dimmed or gradually brightens, and but not limited to this.The offset of compensating basin is from the top of compensating basin
Boundary is gradually dimmed towards the adjoiner of standard regions and compensating basin or gradually brightens.
Disclosure collocation attached drawing describe the offset of compensating basin from right to left, from top to bottom, by directions such as centres to boundary
It is gradual to brighten or dimmed, after keeping the brightness value of compensating basin compensated, level off to the standard values of standard regions, even with standard value
It is identical.Term described in the disclosure, such as " from right to left ", " from top to bottom ", " by centre to boundary " direction, keep the field usual
Skill understands and realizes accordingly the image compensation method of " gradual offset ", is not to want to limit the right of the disclosure
It asks.The protection scope of the disclosure is also fallen with the range that aforementioned multiple directions extend.
Then, microcontroller component 199 accounts for the ratio and those side offsets of the display panel 120 according to side compensating basin, certainly
A fixed sequence, which can be the geometric progression sequence corresponding to those side offsets, as shown in step S120.Citing comes
It says, side compensating basin is to account for the 20% of side perspective images, and side compensating basin is the compensation row (or column) of 5 rows side by side.Multiple side compensation
Value generates multiple whole offsets multiplied by the sequence, to compensate side compensating basin.From the first compensation row of adjacent standard regions to away from
The sequence of the fiveth compensation row farthest from standard regions is to be successively decreased with 4% side offset equal proportion.The sequential value is sequentially from correspondence
Compensating capable side offset to the side offset for corresponding to the 5th compensation row in first is 20%, 16%, 12%, 8%, 4%.
Subsequent, microcontroller component 199 generates multiple whole offsets according to the sequence and those side offsets after operation,
As shown in step S130.For example, every side offset corresponds to the side of the first compensation row multiplied by corresponding sequential value
Offset is multiplied by the side offset of the 20%, second compensation row multiplied by the side offset of 16%, third compensation row multiplied by the 12%, the 4th
The side offset for compensating row compensates the side offset of row multiplied by 4% multiplied by the 8%, the 5th.
Later, according to those whole offsets, the side compensating basin is compensated, as shown in step s 140.
In some embodiments, side perspective images have a standard regions of side compensating basin and the adjacent side compensating basin, such as walk
Shown in rapid S102.Standard regions correspond to the display unit of multiple arrays in display panel 120, and the brightness value of each display unit
It is 128 bits for standard value, such as brightness value.Side compensating basin corresponds to the display unit of multiple arrays in display panel 120, and every
The brightness value of one display unit is the brightness value (i.e. offset) for compensating abnormal bright band, if offset is 28 bits.
In some embodiments, microcontroller component 199 generates after operation according to those standard values and those whole offsets
Whole offset.When those compensate row (or compensating unit) closer to the standard regions, then microcontroller component 199 can compensate those
Those whole offsets are closer to those standard values corresponding to row (or compensating unit), as shown in step S150.For example, more
The multiple compensating units arranged in a straight line of a compensation behavior side by side.According to the corresponding sequential value of each compensation row and corresponding
Multiple compensating units generate the sequential value for corresponding to each compensating unit.The sequential value can be the corresponding sequence of compensation row
Value generates the mean sequence value of the compensating unit divided by the sum of compensating unit.
In some embodiments, the sequential value of each compensating unit can be the sequential value of geometric progression, such as compensating unit
Closer to the center of display panel 120, then the sequential value of the compensating unit is bigger.For example, the sequential value of third compensation row
It is 12%.The first to the 5th compensating unit of first compensation behavior five sequentially from top to bottom, and the first compensation row is mended with third
Repay unit be boundary line, first and the 5th compensating unit it is symmetrical, second and the 4th compensating unit it is symmetrical.So, third
The sequential value of compensating unit is that the sequential value of 12%, the second and the four compensating unit is respectively 8%, the first and the five compensating unit
Sequential value be respectively 4%.
Refering to Fig. 5 to Fig. 8, the MURA type (side view angle overlaps substitution formula offset) of the second class: for display panel 120
The side perspective images of positive perspective images zero defect and display panel 120, which are detected, one or more MURA.For example, so that
Few two acquisition units 110 capture the first side perspective images and second side perspective images of display panel 120 respectively.Then, micro-
After control assembly 199 receives the first, second side perspective images via communication component 193, the analysis of microcontroller component 199 first,
The MURA of second side perspective images, and then the multiple first sides offset for corresponding to side compensating basin is obtained to compensate the first side
The MURA of perspective images, as shown in step S210；And the multiple second side offsets for corresponding to side compensating basin are obtained, to
The MURA for compensating second side perspective images, as shown in step S220.
Subsequent, multiple first sides offset and multiple second side offsets are superimposed on the side compensating basin of display panel 120, such as
Shown in step S230.For example, two acquisition units 110 respectively from the right side of image-forming range N capture right side perspective image with
And left side perspective image is captured from the left side of image-forming range N.Microcontroller component 199 receives left and right side view via communication component 193
Angle image, and the MURA of left and right side perspective images is analyzed, and then provide the multiple of the side compensating basin for corresponding to display panel 120
First side offset, compensating the MURA of left side perspective, and corresponding to multiple second side offsets of the side compensating basin,
Its MURA to compensate right side perspective.
Later, those the first side offsets and those second side offsets are via a substitution program, by those of a part
Second side offset replaces those the first side offsets of a part, as shown in step S240.The substitution program is with a part
Multiple second side offsets replace multiple first sides offset of a part, generate multiple whole compensation in the compensating basin of side
Value, whole offset are that multiple second side offsets of the part and unsubstituted multiple first sides offset are located at side compensation
Area.Specifically, side compensating basin includes the compensation row of multirow side by side, and each compensation row corresponds to a side offset.So,
Replacing program is using the ratio of multiple first sides offset and multiple second side offsets as the foundation replaced.Such as: first
Side offset: second side offset is three: two, is implied that in multiple first sides offset corresponding to three rows compensation row, any two
Those capable the first side offsets are replaced by multiple second side offsets.When the corresponding compensation row a total of nine of side perspective images
Row, corresponding to side offset be sequentially from left to right respectively that the first compensation row corresponds to the first side offset, second and the
Three compensation rows correspond to second side offset, and the 4th compensation row corresponds to the first side offset, and the 5th and the 6th compensation row corresponds to
In second side offset, and so on.
Then, then make those second side offsets of the part and those the first side offset conducts of unsubstituted part
Multiple whole offsets corresponding to side compensating basin, as shown in step S250.
In some embodiments, which can account for according to multiple first sides offset with multiple second side offsets aobvious
Show the ratio of panel 120, multiple whole offsets in the compensating basin of side is generated, such as step S242.That is, with the part
Those second side offsets replace those the first side offsets of the part.For example, working as the corresponding display surface of side perspective images
A total of ten row of plate 120 compensation row, the first side offset accounts for total compensation behavior 60%, and second side offset accounts for total compensation behavior
40%.That is, the first side offset: second side offset is three: two, implies that multiple first corresponding to three rows compensation row
Side offset has those the first side offsets of any two rows compensation row to be compensated by the multiple second side for corresponding to two rows compensation row
Value replaces.
In some embodiments, side compensating basin includes the compensation row of multirow side by side, and each compensation row corresponds to every a line
Whole offset, and the whole offset of every a line is that multiple first sides offset and the compensation of multiple second side are arranged with a preset interval
Value, as shown in step S252.For example, side perspective images a total of ten row of corresponding display panel 120 compensation row, and those
Compensation row respectively corresponds multiple whole offsets.First side offset: second side offset is three: two.So, first to third mend
It repays row and corresponds to the first side offset, the 4th and the 5th compensation row corresponds to second side offset, continues the 6th to the 8th compensation
Row corresponds to the first side offset, and the 9th and the tenth compensation row corresponds to second side offset.Therefore, which is at interval of two
The corresponding multiple first sides offset of compensation row arrangement three rows compensation row.Correspond to multiple second side as the two compensation row to mend
Repay value.
In some embodiments, side compensating basin includes the compensating unit of multiple arrays, and each compensating unit corresponds to often
One whole offset.It is respectively the first side offset and second side offset per two adjacent whole offsets, such as step S254
It is shown.For example, side compensating basin is that two compensation rows are mutual side by side, and each compensation row implies that side is mended there are five compensating unit
Repay the compensating unit that area shares ten arrays.Every two adjacent compensating unit adjoins each other, one of compensating unit pair
Ying Yuyi the first side offsets, another compensating unit correspond to second side offset.
It in some embodiments, can be according to one positioned at multiple first sides offset in compensating basin and multiple second side offsets
Weighted value and generate multiple whole offsets, as shown in step S256.The weighted value can be divided into average weight value and Gauss weighted value.
When showing image is N*N matrix, average weight value is N*N.When showing image is N*N matrix, Gauss weighted value can foundation
Regression analysis and obtaining levels off to 2NAnd N is any real number.For example, when display image is 3*3 matrix, then average weight
Value is 9；Gauss weighted value is 16.When display image is 5*5 matrix, then average weight value is 25；Gauss weighted value is 273.Cause
This, can be with average weight value or Gauss via the multiple first sides offset and multiple second side offsets that replace program and generate
Weighted value arithmetic such as adds, subtracts, multiplication and division, opening radical sign, taking logarithm or other mathematical operation symbols.
Refering to Fig. 9 to Figure 12, the MURA type (just, side view angle overlaps substitution formula offset) of third class: for display panel
The positive perspective images of the one of 120 and at least side perspective images are detected respectively one or more MURA.Such as: three acquisitions are single
Member 110 captures a front image, a left side image and a right side perspective image from the different perspectives of display panel 120 respectively,
And microcontroller component 199 is sent to via communication component 193.Then, the front image and the silhouette are via revision program
It is all the positive perspective images and side perspective images for being parallel to display panel 120 after amendment.
Microcontroller component 199 analyzes one or more MURA of positive perspective images, and obtains corresponding to positive perspective images
