Again one carry be, the present embodiment comprises with these dark lines the first dark line, the second dark line and the 3rd dark line that occur continuously, and the center of the center of the first dark line and the 3rd dark line is at a distance of second distance K, but, because dark line corresponds to the trough of brightness distribution curve C, and bright rays corresponds to the crest of brightness distribution curve C, therefore, as shown in Figure 1B, these troughs can comprise the first trough, the second trough and the 3rd trough that occur continuously, and second distance K also may be defined as the distance between the first trough and the 3rd trough.In this, the first trough or the 3rd trough may correspond between two these electrode section 1431 adjacent, and the second trough corresponds to these electrode section 1431 one of them; Or the first trough or the 3rd trough also may correspond to one of them in these electrode section 1431, and the second trough corresponds between two these electrode section 1431 adjacent, does not limit.Or in another embodiment, these crests can comprise the primary peak, secondary peak and the 3rd crest that occur continuously, and second distance K also may be defined as primary peak and the peak-to-peak distance of the 3rd ripple.
Penetrating brightness and can be tried to achieve by the integration of brightness distribution curve C from the brightness distribution curve C of Figure 1B, pixel P.In other words, brightness distribution curve C is carried out the area under curve that integration obtains, just can obtain it and penetrate brightness.But the penetrance of display panel 1 can be subject to the impact that bright rays and dark line distribute, and in order to analyze the penetrance of display panel 1, that first can analyze pixel P penetrates brightness.If pixel P penetrates brightness for time best, that just can derive display panel 1 entirety penetrates brightness also for best.
In brightness distribution curve, we find, trough place (dark line) brightness (integral area) is less along with the change of second distance K is large.In addition, crest place (bright rays) becomes large along with the large and brightness (integral area) of the change of second distance K, therefore, when spacing (namely the first distance S is at the certain value) of certain electrode section 1431, as long as find the second distance K of corresponding the best (or to be called dark line cycle K, or bright rays cycle K) just can make its overall brightness integration (i.e. luminance integration of dark line cycle K, or the luminance integration of bright rays cycle K) be maximal value, and then make the penetrance of pixel P and display panel 1 for best.
Therefore, the first distance S and second distance K is the factor affecting brightness distribution curve C, that is impact penetrates the factor of brightness, therefore the present embodiment describes its relation with function L (x) containing K, S parameter.Wherein, function L (x) is a brightness distribution curve equation (x is position parameter):

Then, function L (x) of above formula is done the length integration of a bright rays (or dark line) cycle K, and be multiplied by 1/K, the Luminance Distribution integral function f (K) under bright rays (or dark line) the cycle K of unit can be obtained, that is the relation function of unit brightness (Lu) and bright rays (or dark line) cycle K: Lu=f (K).As shown in Figure 2 A, then after carrying out differential to f (K), it is made to equal 0 and get its extreme value:
wherein, L (x)=acos (bx)+csin (dx)+e,
And a, b, c, d, e are the coefficient containing K and S.Therefore, under optimization penetrance can be obtained, bright rays (or the dark line) optimum value (i.e. K_otm) in cycle and the relational expression K=h (S) of the first distance S.
Due to equation: K=h (S) is quite complicated, and therefore, the utility model is Directly solution equation not: K=h (S), but solves this problem with numerical solution.Numerical solution is function L (x) a certain numerical value S being substituted into above formula, and function L (x) is done the length integration of a bright rays (or dark line) cycle K, (because do the integration of length K after being multiplied by 1/K again, so 1/K need be multiplied by again, with the Luminance Distribution integration under the bright rays cycle obtaining unit, i.e. unit brightness Lu), do normalized again, under this numerical value S can be obtained whereby, the relation function Lu=f (K) of unit brightness Lu and bright rays cycle K:
wherein, L (x)=acos (bx)+ccos (dx)+e
Because S brings numerical value into, therefore a, b, c, d, e are only the coefficient containing K; Under finding out this numerical value S again, the optimum value (K_otm) corresponding to maximal value of f (K).Then, continue to repeat above-mentioned calculating with different numerical value S, to obtain optimum value (K_otm) corresponding under different S.Therefore, obtain corresponding optimum value (K_otm) by different numerical value S, the relational expression of the optimum value (K_otm) in the first distance S under optimization penetrance and bright rays (or secretly line) cycle can be obtained: K=h (S).Such as, as S=3 μm, f (K)=-0.13313K2+1.33461K-0.30853, its differential is asked its extreme value after equaling 0 again, and the optimum value that can obtain K is 5.01243 μm; In addition, as S=3.5 μm, f (K)=-0.15858K2+1.75793K-1.82412, its differential is asked its extreme value after equaling 0, the optimum value that can obtain K is 5.54272 μm, by that analogy.Therefore, as shown in Figure 2 B, so the equation (1) that just can obtain K=h (S) be:
K=-0.43715 × S
3+ 4.37035 × S
2-13.49956 × S+17.98982, wherein, 1≤S≤10, and the unit of S and K is micron.
In other words, when the relational expression of K and S meets equation (1), pixel P can be made to have preferably penetrance, and then make display panel 1 have preferably penetrance.But, consider process variation, in the present embodiment, when K and S meets so that display panel 1 can be made during lower inequality to have preferably penetrance:

2-13.49956×S+17.98982)-0.5≤K
≤(-0.43715×S
3+4.37035×S
2-13.49956×S+17.98982)+0.5
Preferably, when K and S more meets following equation, display panel 1 can have better penetrance:
(-0.43715×S
3+4.37035×S
2-13.49956×S+17.98982)-0.3≤K
≤(-0.43715×S
