Shape.And the method for improving the grey jump of display panel display comprises the following steps S1~S3.
Step S1, sets multigroup analog parameter, and the analog parameter includes the width of pixel electrode and the width of public electrode
Degree.
Specifically, using the width of public electrode as W1, the width of pixel electrode is W2, in step S1, is set multigroup
Analog parameter；For example, 9 groups of analog parameters shown in following form.Below to set 9 groups described in following form in step sl
Embodiments of the present invention are described in detail exemplified by analog parameter.
9 groups of analog parameters that table 1 is set
As above described in form, above-mentioned 9 groups of analog parameters are set in the case where craft precision is 8 μm.
S2 under the conditions of every group of analog parameter, tests the display ash jump of the display panel.
Specifically, according to the display ash jump of the 9 groups of analog parameters set in step S1, respectively test display panel, institute
State test result as seen in figures 3-5, wherein, the test result of the 1st~3 group of analog parameter is shown in figure 3, the 4th~7 group of mould
The test result for intending parameter shows that in Fig. 4 the test result of the 8th~9 group of analog parameter is shown in Figure 5.
S3, under the conditions of determining each group analog parameter, whether the display ash jump of the display panel meets the requirements.
Specifically, the grey jump of display for setting display panel shows the condition of uniformity requirements no more than 3 for satisfaction.Such as figure
Shown in 3, in the 1st~3 group of analog parameter, in the range of fabrication error (CD bias) is ± 0.5 μm, only in the 1st group of mould
Intend under Parameter Conditions, the display ash jump of display panel meets the requirements no more than 3；And the 2nd group and the 3rd group of analog parameter condition
Under, the display ash jump of display panel is all higher than 3, and therefore, 2 groups of analog parameters are undesirable.As shown in figure 4, the 4th~
Under the conditions of 7 groups of analog parameters, in the range of fabrication error is ± 0.5 μm, the display ash jump of display panel is all higher than 3, because
This, 4 groups of analog parameters are undesirable.As shown in figure 5, under the conditions of the 8th group of analog parameter, fabrication error for ±
In the range of 0.5 μm, the display ash jump of display panel is more than 3, and therefore, the 8th group of analog parameter is undesirable；9th group of mould
Intend under Parameter Conditions, in the range of fabrication error is ± 0.5 μm, the display ash jump of display panel is no more than 3, therefore, the 9th
Group analog parameter meets the requirements.
According to above-mentioned analysis, when craft precision is 8 μm, in the range of fabrication error is ± 0.5 μm, at the 1st group and the 9th
The grey jump of display of display panel under the conditions of group analog parameter meets the requirement of display homogeneity, it is to be understood that herein
In the case of, according to the 1st group and the 9th group of analog parameter, display panel is prepared, i.e., is 1.6 μm according to the width W1 of public electrode, as
The width of plain electrode W2 is 2.6 μm or is 2.1 μm according to the width of public electrode W1, and the width of pixel electrode W2 is 3.1 μm
Display panel is prepared, then the display ash jump for the display panel prepared can be not more than 3, disclosure satisfy that the display homogeneity of setting
Condition, so that display panel has good display homogeneity.
, whereas if under the conditions of above-mentioned 9 groups of analog parameters, the display ash jump of display panel is all higher than 3, then namely
It says, the display panel that any group of analog parameter in above-mentioned 9 groups is prepared, shows that grey jump can be more than 3, so as to
The requirement for meeting display homogeneity is difficult to, at this moment, it is necessary to reset analog parameter, test the analog parameter of the reset
Whether meet the requirements.
In short, in step s3, if under the conditions of having at least one set of analog parameter, definitive result is grey for the display of display panel
Jump meets display uniformity requirements, then prepares display panel according to satisfactory one or more groups of analog parameters；If
Definitive result is undesirable for the display ash jump of display panel under the conditions of multigroup analog parameter, then needs to reset mould
Intend parameter, repeat step S1~S3, uniformity requirements are shown until obtaining and can meet the grey jump of display of display panel
Analog parameter.
Specifically, in embodiment 1, the width W2 of pixel electrode and the width of public electrode in multigroup analog parameter
Difference between degree W1 differs.Usually, the difference between W2 and W1 for display panel display ash jump have compared with
It is big to influence, that is to say, that as long as W2-W1 is certain numerical value, the numerical value of W2 and W1 can free floating within the specific limits,
And some or several special values are not limited to, it can meet the grey jump of display of display panel and show wanting for homogeneity
It asks.Therefore, above-mentioned setting can make the quantity of the difference between W2 and W1 in multigroup analog parameter most, for example, 10 groups of simulations
In parameter, the difference between W2 and W1 differs, and the quantity for alloing the numerical value of W2-W1 is 10.Such effect is energy
It is enough to increase the satisfactory probability of display ash jump for making display panel in multigroup analog parameter, so as to reduce simulation
The quantity of parameter group thus reduces and the consumed process time is tested in step S2；It more meets the requirements alternatively, obtaining
Analog parameter group, so as to when preparing display panel, can have the process choice scope of bigger；Or repetition can be reduced
The probability of step S1~S3, in this embodiment it is not even necessary to repeat step S1~S3.
In another embodiment 2 of present embodiment, above-described embodiment 1 is different from, in multigroup analog parameter, pixel
The quantity of difference between the width W2 of electrode 10 and the width W1 of public electrode 11 is less than the quantity of analog parameter group.So set
For the purpose put in each group analog parameter is made, there is one or more common differences, so-called common difference in the numerical value of W2-W1
Refer to W2-W1 numerical value be equal to the common difference there are two or more group analog parameter.For example, it is enumerated in embodiment 1 upper
State in 9 groups of analog parameters, there are one common differences for the 1st group of analog parameter and the 9th group of analog parameter tool --- 1 μm, and the 2nd group of mould
Intend parameter then has another common difference with the 4th group of analog parameter --- and 0.5 μm, the 3rd group of analog parameter and the 5th group of simulation are joined
Number has the 3rd common difference --- and 0 μm.
In another embodiment 3 of present embodiment, above-described embodiment 1 and embodiment 2, multigroup simulation ginseng are different from
Number is divided into multiple subsets, and each subset includes at least two groups of analog parameters；The pixel electricity of each group analog parameter in each subset
Difference between the width W2 of pole 10 and the width W1 of public electrode 11 is identical, that is to say, that each group simulation in each subset
Parameter has 1 common difference.For example, in step sl, 12 groups of analog parameters are set, by 12 groups of analog parameters be divided into a, b,
Tri- subsets of c, each subset include 4 groups of analog parameters, and shown in the following form of concrete numerical value of 3 groups of analog parameters：
The analog parameter for 4 subsets that table 2 is set
As shown above, 4 groups of analog parameters in a subsets, between pixel electrode width W2 and public electrode width W1
Difference W2-W1 be 0.5 μm；And 4 groups of analog parameters in b subsets, pixel electrode width W2 and public electrode width W1
Between difference W2-W1 be 0.5 μm of ﹣；And 4 groups of analog parameters in c subsets, pixel electrode width W2 and public electrode
Difference W2-W1 between width W1 is 0 μm.If it is understood that under the conditions of 4 groups of analog parameters in a subsets, show
Show that the grey jump of display of panel meets the requirement of display homogeneity, it, then at least can be by the verification of 4 groups of analog parameters
As long as thinking to meet W2-W1=0.5 μm to a certain extent, i.e., the common difference of 4 groups of analog parameters can make display in a subsets
The grey jump of display of panel meets the requirement of display homogeneity, and prepares display panel according to the common difference accordingly, makes made
The display homogeneity of standby display panel meets the requirements；So can when preparing display panel, be just not limited in a subsets 4
Group technological parameter expands the scope of process choice.On the contrary, and if a are concentrated under the conditions of 1 group or multigroup analog parameter,
The grey jump of display of display panel does not meet the requirement of display homogeneity, then it is assumed that the common difference of the subset can not meet display
The requirement of homogeneity is, it is necessary to reset other common differences.B subsets and c subsets are similar, just repeat no more again.
In short, in above-described embodiment 2 and embodiment 3, if in step S3 pixel electrode 10 width W2 and common electrical
The display ash jump of display panel under the conditions of the identical multigroup analog parameter of difference between the width W1 of pole 11 conforms to
It asks, then according to the difference system between the width of pixel electrode and the width of public electrode common in multigroup analog parameter condition
Standby display panel；When preparing display panel, to realize the purpose for expanding process choice scope.
In another embodiment 4 of present embodiment, above-described embodiment 1~3 is different from, it can also be real by other means
Now expand the purpose of process choice scope.Specifically, as shown in fig. 6, after step s 3, in multigroup analog parameter, if its
In there is institute's definitive result under the conditions of n group analog parameters to meet the requirements for the display ash jump of display panel, and the n group analog parameters
Difference in condition between 11 width W1 of 10 width W2 of pixel electrode and public electrode differs, n >=1；For example, embodiment
The 9 groups of analog parameters included in 1, wherein under the conditions of having 2 groups of analog parameters, the display ash jump of display panel meets display
The requirement of one property, but under the conditions of 2 groups of analog parameters, the numerical value of W2-W1 is identical, it is determined that and the value of n is 1；, whereas if this 2
Under the conditions of group analog parameter, the numerical value of W2-W1 is different, that is, the value for determining n is 2；In these cases, following step S4 is carried out
~S6.
S4 is once again set up multigroup analog parameter, and multigroup analog parameter is divided into n subset, is simulated respectively with above-mentioned n groups
Parameter corresponds to；Each subset includes at least one set of analog parameter, and wherein in each group analog parameter pixel electrode 10 width W2
The width W2 of pixel electrode 10 in difference one group of analog parameter corresponding with the subset between the width W1 of public electrode 11
Difference between the width W1 of public electrode 11 is identical.
S5 under the conditions of every group of analog parameter of each subset, tests the display ash jump of display panel.
S6, under the conditions of determining each group analog parameter, whether the display ash jump of the display panel meets the requirements.
If in step S6, at least one subset, it includes each group analog parameter under the conditions of, institute's definitive result be display surface
The display ash jump of plate meets the requirements, as long as then can at least think that the common difference in the subset can make to a certain extent
The grey jump of display of display panel meets the requirement of display homogeneity, so as to according to each group analog parameter at least one subset
Under the conditions of difference between the width of pixel electrode and the width of public electrode prepare display panel.If conversely, in step S6, often
Height is concentrated, and under the conditions of at least one set of analog parameter, institute's definitive result does not meet for the display ash jump of display panel
It is required that then record the satisfactory analog parameter group of display ash jump that can make display panel in the subset and with the subset
Corresponding one group of analog parameter, and display panel is prepared according to the analog parameter group recorded.
Preferably, each subset in step S4 includes 3 groups or more analog parameters, that is to say, that just each common poor
Value, at least 4 groups of analog parameters come under the simplation verification common difference, and it is aobvious whether the display ash jump of display panel can meet
Show the requirement of homogeneity, so as to improve the accuracy rate of simplation verification.
Specifically, in the pixel of the display panel, each strip public electrode 11 is located at two strip pixel electrodes 10
Between, and the spacing of two strip pixel electrodes 10 of itself and this in the horizontal direction differs, so setting preferably to avoid
The influence of process deviation helps to further improve display homogeneity.In addition, each pixel of the display panel can be double farmlands
Structure, as shown in fig. 7, each pixel includes two farmlands of A, B, double domain structures can improve the colour cast of pixel, improve the standard of display
True property.Specifically, in each pixel of the display panel, double domain structures are set gradually along the first direction to second direction；And
The strip public electrode 11 in a farmland A and the strip pixel electricity positioned at 11 first direction of strip public electrode in a first direction
