Fig. 3 is refer to, Fig. 3 is that the data transfer device for calculating sub-pixel a is illustrated according to an embodiment of this disclosure
Flow chart.For convenience of explanation, the operation of pixel conversion unit 142 shown in FIG. 1 can together be said with data transfer device 300
It is bright.As shown in figure 3, data transfer device 300 include step 301, step 302, step 303, step 304, step 305,306,
Step 303a, step 304a, step 304b, step 305a, step 306a and step 306b.
In step 301, pixel data generation unit 142 receives more pixel data DATA2.It is as it was earlier mentioned, every
One pixel information DATA2 includes red color range value, green color range value, blue color range value and white color range value.
In step 302, pixel data generation unit 142 is by prime color range value compared with first grade color range value.
If first grade color range value is more than or equal to prime color range value, step 303 is performed.Conversely, before if first grade color range value is less than
During grade color range value, then step 305 is performed.
In step 303, pixel data generation unit 142 more by a magnitude D1 compared with first predetermined value TH1,
The absolute value of differences of the middle magnitude D1 between prime color range value and first grade color range value.First predetermined value TH1 can be according to aobvious
Show that the system specification of panel 100 is set, and in advance in the buffer of storage pixel data generation unit 142.If magnitude D1 is more than
Equal to first predetermined value TH1, step 303a is performed.Conversely, if magnitude D1 is less than first predetermined value TH1, step 304 is performed.
In step 303a, after pixel data generation unit 142 confirms that magnitude D1 is more than or equal to first predetermined value TH1, just

Big person).So, it can be ensured that display panel 100 maintains certain brightness, and avoids the edge generation of word on picture jagged
Problem, and then improve the fluency of picture.
For example, by taking the sub-pixel a in the 2nd pixel of Fig. 2 as an example, it is assumed that first predetermined value TH1 is arranged to 64.By
White need to be shown according to color alignment, pixel data generation unit 142 is by prime color range value in the sub-pixel a of the 2nd pixel 124
The white color range W1 ' (being, for example, 16) of the 1st pixel information DATA2 is arranged to, and first grade color range value is set into the 2nd picture
The white color range value W2 ' (being, for example, 128) of plain data DATA2.
In this instance, pixel data generation unit 142 compares prime color range value (16) and first grade color range value (128),
And it learns first grade color range value and is more than prime color range value (i.e. step 302).Pixel data generation unit 142 is according to prime color range
Be worth the mathematic interpolation magnitude D1 (D1=| 16-128 |=112) between first grade color range value, and by compare magnitude D1 with
After first predetermined value TH1, learn that magnitude D1 is more than first predetermined value TH1 (i.e. steps 303).Therefore, pixel data generation unit
The sub-pixel value of sub-pixel a is arranged to first grade color range value (128) by 142.
Referring once again to Fig. 3, in step 304, pixel data generation unit 142 is more by magnitude D1 and second predetermined value
TH2 is compared, and wherein first predetermined value TH1 is more than second predetermined value TH2.It is identical to first predetermined value TH1, second predetermined value
TH2 can be also pre-set at according to actual specification demands in the buffer of pixel data generation unit 142.If magnitude D1 is more than
Equal to second predetermined value TH2, step 304a is performed.Conversely, if magnitude D1 is less than second predetermined value TH2, step 304b is performed.
In step 304a, the sub-pixel value of sub-pixel a is arranged to first grade color range by pixel data generation unit 142
Value and the product of the first weight coefficient X1 and the summation of prime color range value and the product of the second weight coefficient X2.Due to first
Grade color range value is more than prime color range value, and in this instance, the first weight coefficient X1 can set to be more than the second weight coefficient X2, that is,
The first grade color range value with higher brightness is allowed with higher weight.In this way, can make sub-pixel a sub-pixel value have compared with
Enough brightness.
For example, by taking the sub-pixel a in the 2nd pixel of Fig. 2 as an example, it is assumed that first predetermined value TH1 is arranged to 64, and
Second predetermined value TH2 is arranged to 32.Since the sub-pixel a of the 2nd pixel 124 need to show white, pixel number according to color alignment

First predetermined value TH1 (i.e. steps 303).Therefore, pixel data generation unit 142 more by magnitude D1 and second predetermined value TH2 into
Row relatively (i.e. step 304).In this instance, since magnitude D1 is equal to second predetermined value TH2, pixel data generation unit 142 will
The sub-pixel value of sub-pixel a is arranged to the product of first grade color range value and the first weight coefficient X1 and prime color range value and the
The summation of the product of two weight coefficient X2.
Referring once again to Fig. 3, in step 304b, pixel data generation unit 142 sets the sub-pixel value of sub-pixel a
For the average value of prime color range value and first grade color range value.It, can be in prime color range value and the in this way, by such set-up mode
One grade color range value very close to when, make sub-pixel a that there is more uniform brightness performance.
For example, when second predetermined value TH2 is arranged to 16, prime color range value is 24, and when first grade color range value is 16, as
The sub-pixel value of sub-pixel a can be arranged to 20 by plain data generating unit 142.
Step 305,305a, 306, the operation of 306a and 306b and above-mentioned steps 303,303a, 304,304a and
The operation of 304b is similar.Difference is, in step 305,305a, 306,306a and 306b, prime color range value is more than first
This grade of color range value.Therefore, before the sub-pixel value of sub-pixel a can be arranged to by pixel data generation unit 142 in step 305a
Grade color range value (i.e. prime color range value and the greater in first grade color range value).In step 306a, pixel data generates single
The sub-pixel value of sub-pixel a can be arranged to prime color range value and the product of the first weight coefficient X1 and first grade by member 142
The summation of color range value and the product of the second weight coefficient X2.Wherein the first weight coefficient X1 can be more than the second weight coefficient X2, i.e.,
The prime color range value for making brightness higher has more weight, so that sub-pixel a can have certain brightness.
Data transfer device 300 provides three kinds of different subpixel a by first predetermined value TH1 and second predetermined value TH2
Sub-pixel value set-up mode.In this way, can make the sub-pixel value of sub-pixel a via two neighbouring pixel datas and itself
Corresponding pixel data is determined, is showed with the picture brightness for reaching more uniform and smooth.
Fig. 4 is refer to, Fig. 4 is that the data transfer device for calculating sub-pixel c is illustrated according to an embodiment of this disclosure
Flow chart.Data transfer device 400 includes step 401, step 402, step 403, step 404, step 405,406, step
403a, step 404a, step 404b, step 405a, step 406a and step 406b.
In step 401, pixel data generation unit 142 receives more pixel data DATA2.In step 402, as
Plain data generating unit 142 is by secondary color range value compared with second grade color range value.If second grade color range value is more than etc.
When secondary color range value, step 403 is performed.Conversely, when if second grade color range value is less than secondary color range value, step is performed
405。
In step 403, pixel data generation unit 142 more by magnitude D2 compared with first predetermined value TH1, magnitude
D2 is the absolute value of the difference between secondary color range value and second grade color range value.If magnitude D2 is more than or equal to first predetermined value
TH1 performs step 403a.Conversely, if magnitude D2 is less than first predetermined value TH1, step 404 is performed.
In step 403a, after pixel data generation unit 142 confirms that magnitude D2 is more than or equal to first predetermined value TH1, i.e.,
By the sub-pixel value of sub-pixel c be arranged to second value color range value (i.e. secondary color range value with it is larger in second value color range value
Person).
For example, by taking the sub-pixel c in the 2nd pixel of Fig. 2 as an example, it is assumed that first predetermined value TH1 is arranged to 64.By
Green need to be shown according to color alignment, pixel data generation unit 142 is by secondary color range value in the sub-pixel c of the 2nd pixel 124
The green color range value G3 ' (being, for example, 16) of the 3rd pixel information DATA2 is arranged to, and second grade color range value is set the 2nd
The green color range value G2 ' (being, for example, 128) of pixel information DATA2.
In this instance, pixel data generation unit 142 compares secondary color range value (16) and second grade color range value (128),
And it learns second grade color range value and is more than secondary color range value (i.e. step 402).Pixel data generation unit 142 is according to secondary color range
Be worth the mathematic interpolation magnitude D2 (D2=| 16-128 |=112) between second grade color range value, and by compare magnitude D2 with
After first predetermined value TH1, learn that magnitude D2 is more than first predetermined value TH1 (i.e. steps 403).Therefore, pixel data generation unit
The sub-pixel value of sub-pixel c is arranged to second grade color range value (128) by 142.
In step 404, pixel data generation unit 142 is more by magnitude D2 compared with second predetermined value TH2.If amount
Value D2 is more than or equal to second predetermined value TH2, performs step 404a.Conversely, if magnitude D2 is less than second predetermined value TH2, perform
Step 404b.
In step 404a, the pixel value of sub-pixel c is arranged to second grade color range value by pixel data generation unit 142
With the product of the first weight coefficient X1 and the summation of secondary color range value and the product of the second weight coefficient X2.Similarly, due to
Second grade color range value is more than secondary color range value, and in this instance, the first weight coefficient X1 can be set more than the second weight coefficient X2.
In this way, the sub-pixel value of sub-pixel c can be made there is enough brightness.
By taking the sub-pixel c in the 2nd pixel of Fig. 2 as an example, it is assumed that it is predetermined that first predetermined value TH1 is arranged to 64, and second
Value TH2 is arranged to 32.Since the sub-pixel c of the 2nd pixel 124 need to show green according to color alignment, pixel data generates single
Secondary color range value is arranged to the green color range value G3 ' (being, for example, 32) of the 3rd pixel information DATA2 by member 142, and by second
Grade color range value sets the green color range value G2 ' (being, for example, 64) of the 2nd pixel information DATA2.
In this instance, pixel data generation unit 142 is according to the difference between secondary color range value and second grade color range value
Calculate magnitude D2 (D2=| 32-64 |=32), and by magnitude D2 and first predetermined value TH1 is compared after, learn that magnitude D2 is less than
First predetermined value TH1 (i.e. steps 403).Therefore, pixel data generation unit 142 more by magnitude D2 and second predetermined value TH2 into
Row relatively (i.e. step 404).In this instance, since magnitude D2 is equal to second predetermined value TH2, pixel data generation unit 142 will
The sub-pixel value of sub-pixel c is arranged to the product of second grade color range value and the first weight coefficient X1 and secondary color range value and the
The summation of the product of two weight coefficient X2.
In step 404b, the pixel value of sub-pixel c is arranged to secondary color range value and the by pixel data generation unit 142
The average value of two grade color range values.For example, when second predetermined value TH2 is arranged to 16, secondary color range value is 24, and second grade color
When rank value is 16, the sub-pixel value of sub-pixel c can be arranged to 20 by pixel data generation unit 142.
Step 405,405a, 406, the operation of 406a and 406b and above-mentioned steps 403,403a, 404,404a and
The operation of 404b is similar.Difference is only that, in step 405,405a, 406,406a and 406b, secondary color range value is more than the
Two grade color range values.Therefore, the sub-pixel value of sub-pixel c can be arranged to by pixel data generation unit 142 in step 405a
Secondary color range value.In step 406a, the sub-pixel value of sub-pixel c can be arranged to secondary color by pixel data generation unit 142
