Specific implementation mode
Below in conjunction with attached drawing, to the specific embodiment party of a kind of pixel compensation method provided in an embodiment of the present invention and device
Formula is described in detail.It should be noted that described embodiments are only a part of the embodiments of the present invention, rather than it is complete
The embodiment in portion.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Inventor has found under study for action, in display panel shown in FIG. 1, including：One borehole region W, all diggings are surrounded
The display area A of bore region W and non-display area B around display area A；Borehole region W can be used for that camera shooting is arranged
The structures such as head, sensor, inductor or receiver；Certainly, the setting quantity of borehole region W is not limited to 1, can also be arranged
Have multiple, the setting shape of borehole region W can have any shape, and be not specifically limited, the borehole region W in Fig. 1 be with
It is illustrated for circle.Display panel further includes a plurality of data line arranged in parallel (such as D1 to D4), and segment data line can
With by borehole region W, it is specific as shown in Figure 1, labeled as D1, D2 and D3 three data lines by borehole region W, due to digging
The structures such as camera are set in bore region W, so frame (border, such as sparse stain fill area in the W of borehole region
Domain) setting it is relatively narrow, when D1 to D3 is by borehole region W, need to pass through from the border in the W of borehole region, so D1 is extremely
D3 sees not to be straight line on the whole, but is bent in borehole region W so that near the W of borehole region, D1 and its
The spacing L4 between spacing L3 and D1 and D2 between the adjacent data line in left side (being labeled as D4), is less than at other
The spacing of position (position far from borehole region W), L3 and L4 as shown in Figure 1 are respectively less than L1；Similarly, for D3,
Spacing L2 near the W of borehole region between D3 and data line adjacent on the right side of it (being labeled as D5), is also less than in other positions
The spacing of (position far from borehole region W), L2 as shown in Figure 1 are less than L1.
In the making of actual display panel, in the region far from borehole region W, the spacing between adjacent two data line
L1 is not less than 10 μm, not will produce generally and interferes with each other；And near the W of borehole region, L2, L3 and L4 may only have 3 μm or so,
So that spacing between D1 and D4 is smaller, the spacing between D1 and D2 is smaller and spacing between D3 and D5 is smaller, produces each other
Life interferes with each other, and finally influences display effect.
Therefore, for above-mentioned display panel, an embodiment of the present invention provides a kind of pixel compensation methods, to improve this kind
The display effect of display panel.
It should be noted that pixel compensation method provided in an embodiment of the present invention, is directed to be provided in display area
The display panel in borehole region, but it is specific there is no carrying out to the setting quantity in borehole region, installation position, and setting shape
It limits, as long as being provided with borehole region in display area, belongs to invention which is intended to be protected.
Specifically, above-mentioned pixel compensation method provided in an embodiment of the present invention, as shown in Fig. 2, may include：
S201, sub-pixel to be compensated in the pixel of display panel is determined；
Coupled capacitor between S202, the data line and adjacent data line that are correspondingly connected with according to sub-pixel to be compensated, and
Positioned at the grayscale of the sub-pixel on sub-pixel periphery to be compensated, the grayscale of sub-pixel to be compensated is compensated.
For above-mentioned display panel, using pixel compensation method provided in an embodiment of the present invention, can determine to show first
Show the sub-pixel to be compensated in panel, since a data line connects multiple sub-pixels, it is possible to utilize sub-pixel to be compensated
The ash of the sub-pixel of coupled capacitor and sub-pixel periphery to be compensated between the data line and adjacent data line that are correspondingly connected with
Rank, realization compensates the grayscale of sub-pixel to be compensated, to improve display effect.
In the specific implementation, in order to determine sub-pixel to be compensated, step S201 in embodiments of the present invention is true
Determine the sub-pixel to be compensated in the pixel of display panel, can specifically include：
According between two data line of the input sequence of the grayscale of each row sub-pixel and arbitrary neighborhood in display panel
Spacing determines the sub-pixel to be compensated in the pixel of display panel.
Specifically, display panel may include：The multiple pixels 2 being arranged in array, as shown in figure 3, Fig. 3 is real in Fig. 1
The close-up schematic view of wire frame 1, and each pixel 2 includes：Red sub-pixel R, green sub-pixels G and blue subpixels B,
And one row sub-pixel only have a kind of color；Display panel can also include：The multiple selector 3 being connected with data line, such as Fig. 1
It is shown, for inputting grayscale signal for data line, to realize display function.Also, it is inputted for each data line in multiple selector 3
When grayscale signal, it can input in the following way：Successively grayscale is inputted to the data line that different colours sub-pixel is correspondingly connected with
Signal.For example, the data line that is first correspondingly connected with to red sub-pixel while inputting grayscale signal, then gives green sub-pixels to correspond to and connect
The data line that connects while grayscale signal is inputted, the data line being finally correspondingly connected with to blue subpixels while inputting grayscale signal.
If according to such input mode, when the spacing between adjacent data line is too small, in the number of rear input grayscale signal
According to line can to formerly input grayscale signal data line generate interference, i.e., it is preceding input grayscale signal data line can be by rear
Input the signal interference of the data line of grayscale signal；For example, structure shown in Fig. 3, if the sub-pixel that D1 is correspondingly connected with is green
Sub-pixels G, the sub-pixel that adjacent data line D4 is correspondingly connected on the left of D1 is red sub-pixel R, then D4 is first inputted
Grayscale signal inputs grayscale signal after D1, so D4 can be generated interference by the grayscale signal on D1；For another example, connect if D2 is corresponded to
The sub-pixel connect is blue subpixels B, and the sub-pixel that D1 is correspondingly connected with is green sub-pixels G, then D1 first inputs grayscale signal,
D2 recently enters grayscale signal, thus D1 can by the grayscale signal on D2 generate interference, and D2 due to be in each data line most
Input signal afterwards, so will not be by any interference.
Therefore, be based on above-mentioned analysis, in embodiments of the present invention, according in display panel the grayscale of each row sub-pixel it is defeated
Enter the spacing between sequence and two data line of arbitrary neighborhood, determines the sub-pixel to be compensated in the pixel of display panel, it can
To specifically include：
Determine that the input sequence of the grayscale of each row sub-pixel is followed successively by：It is each row red sub-pixel, each row green sub-pixels, each
Row blue subpixels；Wherein, each row sub-pixel with same color inputs grayscale simultaneously；
Determine whether the spacing between two data line of arbitrary neighborhood meets preset condition；
When the spacing between determining two data line of arbitrary neighborhood meets preset condition, determines to exist in display panel and wait for
Sub-pixel is compensated, and each red sub-pixel that the data line for meeting preset condition is correspondingly connected with and each green sub-pixels are determined as
Sub-pixel to be compensated；Wherein, a row sub-pixel is correspondingly connected with a data line.
Wherein, preset condition can be：Any position is smaller than predetermined threshold value between adjacent two data line, also
It is to say, between adjacent data line, as long as there are one both positions when being smaller than predetermined threshold value, you can judge to meet and preset item
Part；Based on this, meeting the data line of preset condition can be：By the data line in borehole region, and with pass through borehole region
Data line is adjacent and data line except the borehole region.
As shown in figures 1 and 3, by taking D1 and D2 as an example, although D1 and D2 spacing in the region except solid box 1 is L1,
But when in the W of borehole region, the spacing of the two is then L4, it is evident that L4 ratios L1 is much smaller, in actual manufacturing process, and L1
Generally 10 μm, and L4 may be small to 3 μm, therefore, D1 and D2 are the data lines for meeting preset condition.Similarly, D4, D3 and D5
It is the data line for meeting preset condition.
Therefore, if being followed successively by according to the input sequence of the grayscale of each row sub-pixel：Each row red sub-pixel, each row green
When pixel, each row blue subpixels, in conjunction with partial schematic diagram shown in Fig. 3, the red sub-pixel R being correspondingly connected with D4 and D3 is equal
For sub-pixel to be compensated, same as the green sub-pixels G of D1 and D5 connections is sub-pixel to be compensated.
In actual implementation, in fact not necessarily according to each row red sub-pixel, each row green sub-pixels, each row blue
The input sequence of sub-pixel inputs grayscale signal for the data line that is correspondingly connected with, can also be certainly according to：The sub- picture of each row green
Plain, each row blue subpixels, each row red sub-pixel sequentially input, and the spacing between adjacent data line meets preset condition
Under the premise of, then at this point, the data line that green sub-pixels are correspondingly connected with, it can be by respectively from blue subpixels and red
The signal interference of the data line of the corresponding connection of pixel；The data line of the corresponding connection of blue subpixels, can be by from red
The signal interference for the data line that sub-pixel is correspondingly connected with；And for red sub-pixel, due to being the grayscale signal recently entered, institute
With will not be by any interference.Based on this, the green sub-pixels and indigo plant that the data line for meeting preset condition can be correspondingly connected with
Sub-pixels are determined as sub-pixel to be compensated.Therefore, it in conjunction with shown in Fig. 3, in this case, then will be connect with D1 and D5 green
Sub-pixels G is determined as sub-pixel to be compensated, and the blue subpixels B being connect with D2 is determined as sub-pixel to be compensated.
Certainly, in addition to the above, can also be according to：Each row blue subpixels, each row red sub-pixel, each row
Green sub-pixels, under the premise of the spacing between adjacent data line meets preset condition, then at this point, blue subpixels correspond to
The data line of connection, can be by dry respectively from the signal of red sub-pixel and the data line of the corresponding connection of green sub-pixels
It disturbs；The data line that red sub-pixel is correspondingly connected with, can be dry by the signal of the data line from the corresponding connection of green sub-pixels
It disturbs；And for green sub-pixels, due to being the grayscale signal recently entered, so will not be by any interference.It, can be with based on this
Blue subpixels and red sub-pixel that the data line for meeting preset condition is correspondingly connected with are determined as sub-pixel to be compensated.Cause
The red sub-pixel R being connect with D4 and D3 in this case, is then determined as sub-pixel to be compensated by this in conjunction with shown in Fig. 3,
The blue subpixels B being connect with D2 is determined as sub-pixel to be compensated.
Therefore, in conjunction with above-mentioned analysis, it was determined which sub-pixel is determined as sub-pixel to be compensated and each row
The grayscale input sequence of pixel has very important relationship, so when determining sub-pixel to be compensated, it is necessary first to determine
The grayscale input sequence of each row sub-pixel.
Following example is followed successively by according to the input sequence of the grayscale of each row sub-pixel：It is each row red sub-pixel, each
Row green sub-pixels, each row blue subpixels illustrate.
In the specific implementation, gray scale compensation is carried out to sub-pixel to be compensated in order to realize, improves display effect, in the present invention
Coupled capacitor between data line and adjacent data line that step S202 in embodiment is correspondingly connected with according to sub-pixel to be compensated,
And the grayscale of the sub-pixel positioned at sub-pixel periphery to be compensated, the grayscale of sub-pixel to be compensated is compensated, it can be specific
Including：
Step 1: determining the coupled capacitor between the data line and adjacent data line that sub-pixel to be compensated is correspondingly connected with；
Wherein, in the coupled capacitor between determining the data line and adjacent data line that sub-pixel to be compensated is correspondingly connected with,
It can be determined according to the grayscale input sequence for each row sub-pixel determined in the above, that is to say, that in each sub- picture of row
The input sequence of grayscale of element is：When each row red sub-pixel, each row green sub-pixels, each row blue subpixels, for waiting mending
Red sub-pixel is repaid, coupled capacitor may include：The data line that red sub-pixel to be compensated is correspondingly connected with and each side phase
Coupled capacitor between two adjacent data lines；For green sub-pixels to be compensated, coupled capacitor may include：Green to be compensated
Coupled capacitor between data line and each side adjacent a data line that sub-pixel is correspondingly connected with.
For example, six data lines are illustrated only shown in Fig. 4, in figure, and the sub-pixel being connected respectively with each data line, and
If when being smaller than predetermined threshold value of any position between six data lines, from left to right by 6 data lines shown in figure
It is denoted as Rn-1, Gn-1, Bn-1, Rn, Gn and Bn successively, wherein Rn-1 indicates the data that the (n-1)th row red sub-pixel is correspondingly connected with
Line, similarly, Gn-1 indicate that the data line that the (n-1)th row green sub-pixels are correspondingly connected with, Bn-1 indicate the (n-1)th row blue subpixels pair
The data line that should be connected, Rn indicate that the data line that the n-th green red sub-pixel of row is correspondingly connected with, Gn indicate the n-th row green sub-pixels
The data line being correspondingly connected with, Bn indicate the data line that the n-th row blue subpixels are correspondingly connected with.
Since the corresponding data line of red sub-pixel first inputs grayscale signal, followed by the corresponding data line of green sub-pixels
Grayscale signal is inputted, is finally the data line input grayscale signal that blue subpixels are correspondingly connected with, therefore, for Rn, by
To the interference of Gn-1, Bn-1, Gn and Bn, so the coupled capacitor between Rn and adjacent data line is：Gn-1, Bn-1, Gn and Bn
The coupled capacitor formed between Rn respectively.For Gn, interfered by Bn-1 and Bn, thus Gn and adjacent data line it
Between coupled capacitor be：The coupled capacitor of the Bn-1 and Bn formation between Gn respectively.
That is, the coupled capacitor between data line and adjacent data line that sub-pixel to be compensated is correspondingly connected with can wrap
It includes：Coupled capacitor between data line and at least one adjacent data line that sub-pixel to be compensated is correspondingly connected with.
Step 2: determining the grayscale for adjacent particular sub-pixel of going together with sub-pixel to be compensated；
Wherein, determining that the input sequence of the grayscale of each row sub-pixel is followed successively by：Each row red sub-pixel, each row green
When sub-pixel, each row blue subpixels, when sub-pixel to be compensated is red sub-pixel to be compensated, particular sub-pixel is to wait mending with this
Repay the green sub-pixels and blue subpixels that red sub-pixel is gone together and left and right is adjacent；Sub-pixel to be compensated is green to be compensated
When pixel, particular sub-pixel is and the blue subpixels that green sub-pixels to be compensated are gone together and left and right is adjacent.
For example, in conjunction with shown in Fig. 4, each sub-pixel in figure is marked respectively first, label result can be found in as shown in the figure,
In the grayscale for determining particular sub-pixel, it is necessary first to the position for determining particular sub-pixel, with RmnFor, particular sub-pixel is
Gm(n-1)、Bm(n-1)、GmnAnd Bmn；For GmnFor, particular sub-pixel Bm(n-1)And Bmn。
Step 3: determining the grayscale of a upper sub-pixel adjacent with particular sub-pixel same column；
Wherein, when the grayscale input time of particular sub-pixel is later than the grayscale input of the adjacent upper sub-pixel of same column
Between；For example, in conjunction with shown in Fig. 4, if particular sub-pixel is Bmn, a upper sub-pixel adjacent with its same column is B(m-1)n；If specific
Sub-pixel is Gmn, a upper sub-pixel adjacent with its same column is G(m-1)n；Similarly, if particular sub-pixel is Bm(n-1), same with it
It is B to arrange an adjacent upper sub-pixel(m-1)(n-1)；If particular sub-pixel is Gm(n-1), a upper sub-pixel adjacent with its same column
For G(m-1)(n-1)。
Step 4: determining the grayscale difference between a particular sub-pixel upper sub-pixel adjacent with same column；
Step 5: according to the coupled capacitor and grayscale difference determined, the gray scale compensation of sub-pixel to be compensated is determined
Value；
Specifically, the gray scale compensation value that following formula calculates sub-pixel to be compensated may be used；
VRnm=[△ VG(n-1)m×Cn_RGL+△VGnm×Cn_RGR+△VB(n-1)m×Cn_RBL+
△VBnm×Cn_RBR]/CRn；
VGnm=(△ VB(n-1)m×Cn_GBL+△VBnm×Cn_GBR)/CGn；
Wherein, VRnmIndicate the gray scale compensation value for being located at the red sub-pixel to be compensated of m rows in the n-th row red sub-pixel,
VGnmIndicate the gray scale compensation value for being located at the green sub-pixels to be compensated of m rows in the n-th row green sub-pixels, △ VG(n-1)mIt indicates
Grayscale difference between the green sub-pixels and the green sub-pixels of m-1 rows of m rows in the (n-1)th row green sub-pixels,
△VGnmIt indicates to be located at the ash in the n-th row green sub-pixels between the green sub-pixels and the green sub-pixels of m-1 rows of m rows
Scale value, △ VB(n-1)mIndicate to be located at blue of the blue subpixels of m rows and m-1 rows in the (n-1)th row blue subpixels
Grayscale difference between pixel, △ VBnmIndicate to be located at the blue subpixels and m-1 rows of m rows in the n-th row blue subpixels
Grayscale difference between blue subpixels, Cn_RGLIndicate that the data line that the n-th row red sub-pixel is correspondingly connected with is adjacent with left side
Coupled capacitor between the data line that (n-1)th row green sub-pixels are correspondingly connected with, Cn_RGRIt indicates that the n-th row red sub-pixel corresponds to connect
Coupled capacitor between the data line that the data line that connects the n-th row green sub-pixels adjacent with right side are correspondingly connected with, Cn_RBLIt indicates
The data line that data line that n-th row red sub-pixel is correspondingly connected with, the (n-1)th row blue subpixels adjacent with left side are correspondingly connected with

The basic capacitance of the data line of connection, n are not less than 0 not less than 1, m.
For example, in conjunction with partial schematic diagram shown in Fig. 3, for the ease of understanding and illustrating, part sub-pixel is carried out in figure
Label, label result can be found in the lower right corner of sub-pixel；For the sub-pixel P7 to be compensated being connect with D3, in conjunction with above-mentioned
Formula can obtain：VP7=[(VP3-VP4)×CD3-D1+(VP5-VP6)×CD3-D2+(VP9-VP10)×CD3-D5+(VP11-VP12)×
CD3-D6]/CD3.It is located in the W of borehole region due to only having D1 to D3, and D1 and D2 are located at the left side in the W of borehole region
The regions border, D3 are located at the right side regions border in the W of borehole region, so for D3, the spacing between D3 and D5
It is smaller, and the spacing between D3 and D2, D3 and D1 and D3 and D6 is larger, therefore coupled capacitor between them is smaller and can
To ignore, therefore, above-mentioned calculating formula can be further represented as：VP7=[(VP9-VP10)×CD3-D5]/CD3.Again because of VP9With
VP10Numerical value both from driving IC, so the numerical value of the two can from driving IC in obtain, CD3-D5Coupling between D3 and D5
Capacitance is closed, can be learnt by capacitance calculation formula, CD3For the basic capacitance (coupling between such as D3 and other signal wires on D3
Capacitance), it is consequently possible to calculate obtaining the offset V that P7 needsP7, to before inputting grayscale signal to P7 by D3, just carry
Before compensate and then the grayscale after compensation be input in P7, to improve display effect.
In another example for the sub-pixel P9 to be compensated being connect with D5, can be obtained in conjunction with above-mentioned formula：VP9=[(VP5-
VP6)×CD5-D2+(VP11-VP12)×CD5-D6]/CD5, it is located at due to D2 in the left side border of borehole region W, D5 is positioned at borehole
Normal region except on the right side of the W of region, so the spacing between D2 and D5 is larger, coupled capacitor between the two is smaller to neglect
Slightly disregard, and the spacing between D5 and D6 is L1, coupled capacitor between the two can also be ignored not only, so obtaining VP9=0,
That is it is not necessarily to compensate for the grayscale of P9.
Step 6: according to the gray scale compensation value of sub-pixel to be compensated, the grayscale of sub-pixel to be compensated is compensated.
That is, before inputting grayscale to sub-pixel to be compensated, just mended in advance using calculated offset
It repays, then the grayscale after compensation is input in sub-pixel to be compensated, the grayscale of sub-pixel to be compensated is mended to realize
It repays, improves display effect.
Therefore, above-mentioned pixel compensation method provided in an embodiment of the present invention does not need to carry out the structure of display panel
It improves, it is only necessary to the offset of sub-pixel to be compensated is precomputed, then by driving IC to be carried out automatically using the offset
It is input to again in corresponding sub-pixel to be compensated after compensation, realizes driving IC direct compensations, carried for the implementation of pixel compensation
