It is because of display panel it should be noted why picture shown on display panel to be adjusted
When normally being shown, the electricity being filled in the pixel of two adjacent rows is had a certain difference, and so, will lead to
There is visual microgroove in the display picture that display panel is presented, which easily influences user and use the ornamental of the display panel
Therefore effect to solve this problem, needs to be adjusted picture shown on display panel, make up data line with this
Itself has defect brought by certain resistance, so that microgroove no longer occurs in the display picture.It will be apparent that thus may be used
To find out, preset display mode above-mentioned refers to that microgroove no longer occurs in display panel.
Wherein, step S3 is specifically included: firstly, picture shown on display panel is adjusted, so that display
No longer there is microgroove in picture shown by panel, at this point, then acquired in obtaining step S1, positioned at fourth line, tertial indigo plant
The grayscale value of sub-pixels B；Then, it is divided again according to gamma, obtains reality corresponding with the grayscale value of blue subpixels B
Border data voltage.It is understood that at this point, the real data voltage of blue subpixels B should be greater than it in step s 2
Acquired termination data voltage.
S4, according to initial data voltage, terminate data voltage and real data voltage, and according to preset algorithm, obtain
Reference voltage change rate.
Specifically, in this step, according to initial data voltage value acquired in step S2, data voltage is terminated, and
Real data voltage acquired in step S3, and according to preset algorithm, to obtain reference voltage change rate.Wherein, herein pre-
Imputation method can be c=(VB-VA)/(VC-VA)；Wherein, c is benchmark voltage change ratio, VAFor initial data voltage, VBTo terminate
Data voltage, VCFor real data voltage.
S5, according to initial grayscale value, terminate grayscale value and reference voltage change rate, obtain actual gray value, and generate

It should be noted that initial grayscale value, termination grayscale value herein is known grayscale value, i.e., it is as shown in Figure 3,
The numerical value such as 0,32,64,96 positioned at the first row are the initial grayscale value of the present embodiment, positioned at 0,32,64,96 etc. of first row
Numerical value is the termination grayscale value of the present embodiment.
That is, in this step, obtaining known initial grayscale value first, terminating grayscale value；Then, according to gamma
Partial pressure obtains initial data voltage V corresponding with the initial grayscale value, termination grayscale value respectivelyA, terminate data voltage VB, and
According to reference voltage change rate c acquired in step S4 and preset algorithm c=(VB-VA)/(VC-VA), it can be obtained reality
Data voltage VC；Finally, being divided again according to gamma, obtain and real data voltage VCCorresponding actual gray value, such as:
When initial grayscale value is 32, and termination grayscale value is 64, actual gray corresponding with the two can be obtained according to preset algorithm
Value 65.So, step S5 is repeated several times, it can generate the first mapping table as shown in Figure 3 namely different initial ashes
Rank value, the mapping table for terminating grayscale value and different actual gray values.
S6, according to step S5 the first mapping table generated, when display panel is shown, to the data on data line
Voltage is adjusted.
Specifically, when being scanned to certain a line grid line, the pixel of the row can be switched on, at this point, according to step S5
First mapping table generated, the data voltage on data line connected respectively to each sub-pixel of the row are adjusted,
So that each sub-pixel of the row can normally be shown.
S7, display panel is obtained when being shown according to the first mapping table, the display pattern of each subregion, and according to
Display pattern is adjusted numerical value store in the second mapping table, corresponding with the subregion, and according to adjustment result pair
Data voltage on data line is adjusted again；Wherein, the second mapping table is that different subregions are closed from the corresponding of different numerical value
It is table.
It should be noted that the display pattern of above-mentioned each subregion refers to: display panel is according to the first mapping table
When being shown, whether each subregion there is the case where microgroove.In addition, the difference stored in above-mentioned the second mapping table referred to
The magnitude range of numerical value is 0~255；Wherein, numerical value 128 is that benchmark numerical value namely display panel are generated according to step S5
When first mapping table is shown, if numerical value corresponding to certain sub-regions is 128, the data electricity of the subregion is implied
Data voltage corresponding to actual gray value in pressure as the first mapping table, then display picture shown by the subregion will not
There is microgroove.Correspondingly, then implying that the subregion is shown when the numerical value corresponding to certain sub-regions is more than or less than 128
There are microgrooves for the display picture shown.
Specifically, the display panel of the present embodiment includes the multiple subregions being arranged in array, wherein as shown in figure 4, this
Embodiment is divided into 28 sub-regions (i.e. X1Y1 subregion, X1Y2 sub-district shown in Fig. 4 with the display area of display panel
Domain, X1Y3 subregion, X1Y4 subregion, X2Y1 subregion etc.) for be illustrated.
Step S7 includes: to obtain every when display panel is shown according to step S5 the first mapping table generated
The display pattern of sub-regions, if at this point, the display pattern of X1Y1 subregion is obtained, X1Y1 is worked as by taking X1Y1 subregion as an example
When microgroove does not occur in subregion, then X1Y1 subregion numerical value corresponding in the second mapping table should be 128, at this point, nothing
Data voltage on data line need to be adjusted；When microgroove occurs in X1Y1 subregion, then to storing in the second mapping table
Numerical value corresponding to X1Y1 subregion is adjusted, so that until X1Y1 subregion no longer microgroove occurs；Wherein, when adjusted
When numerical value is greater than 128, then it represents that data voltage required for the X1Y1 subregion should be greater than the practical ash in the first mapping table
Data voltage corresponding to rank value, at this point, the data voltage on data line should be increased to solve the problems, such as microgroove；Work as adjustment
Numerical value afterwards is less than 128, then it represents that data voltage required for the X1Y1 subregion should be less than the reality in the first mapping table
Data voltage corresponding to grayscale value, at this point, the data voltage on data line should be reduced to solve the problems, such as microgroove.
