Voltage V
StProvided by data driver 110, and an end of main storage electrode line 252 is to be connected to data driver 110.One end of branch's storage electrode line 250 (1) is to be coupled to main storage electrode line 252 through contact hole group 27 (1) and transparency electrode 272 (1), and the position that couples of contact hole group 27 (1) and main storage electrode line 252 is to be B (1).And an end of branch's storage electrode line 250 (2) is to be coupled to main storage electrode line 252 through contact hole group 27 (2) and transparency electrode 272 (2), and the position that couples of contact hole group 27 (2) and main storage electrode line 252 is to be B (2).Wherein, the path-length that couples between position B (1) and the data driver 110 is to be L1 ', is to be (L1 '+L2 ') and couple path-length between position B (2) and the data driver 110.
Contact hole group 27 (1) comprises contact hole 270 (1) and 270 (2), and the aperture area summation of contact hole 270 (1) and 270 (2) is total aperture area of contact hole group 27 (1).And contact hole group 27 (2) comprises contact hole 270 (3) and 270 (4), and the aperture area summation of contact hole 270 (3) and 270 (4) is total aperture area of contact hole group 27 (2).
Different for fear of path-length, cause branch's storage electrode line 250 (1) and 250 (2) V that receive
StInconsistent, the total aperture area of contact hole group 27 (2) needs greater than contact hole group 27 (1), so that branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110.In other words, because path-length (L1 '+L2 ') greater than path-length L1 ', so the aperture area of contact hole 270 (3) and 270 (4) needs accordingly greater than contact hole 270 (1) and 270 (2), so that branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110.
Because branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110, so, the voltage V that branch's storage electrode line 250 (1) to 250 (n) receives
StWill be equal in fact.
Please refer to Fig. 7, its illustrate be among Fig. 6 along the synoptic diagram of 7-7 profile line.Main storage electrode line 252 is the tops that are arranged at substrate 220, and insulation course 251 is the tops that are arranged at main storage electrode line 252.Branch's storage electrode line 250 (1) is the top that is arranged at part insulation course 251, and insulation course 253 is the tops that are arranged at branch's storage electrode line 250 (1) and part insulation course 251.
Contact hole 270 (1) and 270 (2) has respectively aperture area A1 and A2, exposing respectively main storage electrode line 252 and branch's storage electrode line 250 (1), and the size of aperture area A1 and A2 is that path-length L1 ' according to Fig. 8 gets.
Transparency electrode 272 (1) is to be arranged at contact hole 270 (1) and 270 (2) tops, so that branch's storage electrode line 250 (1) is electrically connected to main storage electrode line 252 through contact hole 270 (2), transparency electrode 272 (1) and contact hole 270 (1).
Please refer to Fig. 8, its illustrate be among Fig. 6 along the synoptic diagram of 8-8 profile line.Main storage electrode line 252 is the tops that are arranged at substrate 220, and insulation course 251 is the tops that are arranged at main storage electrode line 252.Branch's storage electrode line 250 (2) is the top that is arranged at part insulation course 251, and insulation course 253 is the tops that are arranged at branch's storage electrode line 250 (2) and part insulation course 251.
Contact hole 280 (3) and contact hole 280 (4) have respectively aperture area A3 and A4, exposing main storage electrode line 252 and branch's storage electrode line 250 (2), and the size of aperture area A3 and A4 is that path-length (L1 '+L2 ') according to Fig. 8 gets.Because the large expression resistance value of the aperture area of contact hole is lower, so the aperture area of contact hole 270 (3) and 270 (4) namely needs relatively greater than contact hole 270 (1) and 270 (2), so that branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110.
Transparency electrode 272 (2) is to be arranged at contact hole 270 (3) and 270 (4) tops, so that branch's storage electrode line 250 (2) is electrically connected to main storage electrode line 252 through contact hole 270 (4), transparency electrode 272 (2) and contact hole 270 (3).
Please refer to Fig. 9, it illustrates is equivalent circuit diagram for Fig. 6.Form resistance R 1 between data driver 110 and the transparency electrode 272 (1), and form resistance R 1 ' between transparency electrode 272 (1) and the branch's storage electrode line 250 (1).And be to form resistance R 2 between transparency electrode 272 (1) and the transparency electrode 272 (2), and form resistance R 2 ' between transparency electrode 272 (2) and the branch's storage electrode line 250 (2).
The first embodiment is according to data driver 110 and respectively couple path-length size between the position, determine the aperture area of contact hole 270 (1) to 270 (4) (as shown in Figure 5), so that (R1+R1 ') equal (R1+R2+R1 ').In other words, because the large expression resistance value of the aperture area of contact hole is lower, so the aperture area of contact hole 270 (3) and 270 (4) needs greater than contact hole 270 (1) and 270 (2), so that branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110.
Because branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110, so, the voltage V that branch's storage electrode line 250 (1) to 250 (2) receives
StWill be equal in fact.
Please refer to Figure 10, it illustrates is two part synoptic diagram for the first embodiment.In addition, when the aperture area of each contact hole is identical, also can adjust the contact hole number of each contact hole group according to the path-length that respectively couples between position and the data driver 110, so that each branch's storage electrode line is equal in fact to the resistance of data driver 110.
As shown in figure 10, the path-length that couples between position B (1) and the data driver 110 is to be L1 ', is to be (L1 '+L2 ') and couple path-length between position B (2) and the data driver 110.Contact hole group 27 (1) comprises M1 contact hole 270 (1) and 270 (2), and contact hole group 27 (2) comprises M2 contact hole 270 (3) and 270 (4).Contact hole number M1 and M2 are non-vanishing positive integers, and the number of contact hole number M1 depends on path-length L1 ', and the number of contact hole number M2 depends on path-length (L1 '+L2 ').
In other words because the contact hole number gets over multilist and shows that resistance value is lower, so contact hole number M2 need accordingly greater than contact hole number M1 so that branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110.
Because branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110 will be so the voltage Vst that branch's storage electrode line 250 (1) to 250 (2) receives will be equal in fact.
In addition, also can be in contact with it the hole area size by the contact hole number of controlling each contact hole group simultaneously, so that each branch's storage electrode line is equal in fact to the resistance of data driver 110.
The second embodiment
The compensation section 510 (1) to 510 (n) that Fig. 7 illustrates for example is respectively compensating line.For convenience of description, following the second embodiment is as the example explanation take two compensating lines and two branch's storage electrode lines, but do not limit to claim of the present invention, the present invention also can use more compensating lines and couple with multiple-limb storage electrode line more, so that the voltage V that each branch's storage electrode line receives
StReach unanimity.
Please refer to Figure 11, it illustrates is part synoptic diagram for one of second embodiment.Voltage V
StProvided by data driver 110, and an end of main storage electrode line 252 is to be connected to data driver 110.One end of compensating line 310 (1) is to be coupled to main storage electrode line 252 through contact hole group 27 (1) and transparency electrode 272 (1), and the other end of compensating line 310 (1) is coupled to an end of branch's storage electrode line 250 (1).And an end of compensating line 310 (2) is to be coupled to main storage electrode line 252 through contact hole group 27 (2) and transparency electrode 272 (2), and the other end of compensating line 310 (2) is coupled to an end of branch's storage electrode line 250 (2).
Contact hole group 27 (1) also comprises contact hole 270 (1) and 270 (2), and the position that couples of contact hole group 27 (1) and main storage electrode line 252 is to be B (1).And contact hole group 27 (2) comprises contact hole 270 (3) and 270 (4), and the position that couples of contact hole group 27 (2) and main storage electrode line 252 is to be B (2).
The track lengths of compensating line 310 (1) depends on the path-length L1 ' that couples between position B (1) and the data driver 110.And the track lengths of compensating line 310 (2) depends on the path-length that couples between position B (2) and the data driver 110 (L1 '+L2 ').
Because the shorter expression resistance value of the track lengths of transmission line is lower, so the track lengths of compensating line 310 (2) need relatively be shorter than compensating line 310 (1), so that branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110.
Because branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110, so, the voltage V that branch's storage electrode line 250 (1) to 250 (2) receives
StWill be equal in fact.
Please refer to Figure 12, it illustrates is the second part synoptic diagram for the second embodiment.In addition, also can adjust the trace width of each compensating line according to the path-length that respectively couples between position and the data driver 110, so that each branch's storage electrode line is equal in fact to the resistance of data driver 110.
As shown in figure 12, the path-length that couples between position B (1) and the data driver 110 is to be L1 ', is to be (L1 '+L2 ') and couple path-length between position B (2) and the data driver 110.The trace width of compensating line 310 (1) depends on path-length L1 ', and the trace width of compensating line 310 (2) depends on path-length (L1 '+L2 ').
Because the larger expression resistance value of the trace width of transmission line is lower, so the trace width of compensating line 310 (2) needs relatively greater than compensating line 310 (1), so that branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110.
Because branch's storage electrode line 250 (1) and 250 (2) equal in fact to the resistance of data driver 110, so, the voltage V that branch's storage electrode line 250 (1) to 250 (2) receives
StWill be equal in fact.
The 3rd embodiment
The compensating unit 50 that Fig. 4 illustrates for example one has cancellated transmission line, following the 3rd embodiment has cancellated transmission line with one to be coupled between data driver 110 and each the branch's storage electrode line, so that each branch's storage electrode line is identical in fact with resistance between the data driver 110.

Vertical cabling 430 (a) is in order to the horizontal cabling 420 of vertical connection (a) and 420 (b), and similarly disposes abreast with spacing d1.Vertical cabling 430 (a) is to be staggered with branch's storage electrode line 250 (1) to 250 (9), and is to equate in fact with the distance of branch storage electrode line 250 (1) to 250 (9).In other words, the distance of the vertical adjacent two branch's storage electrode lines with the left and right sides of cabling 430 (a) is all between 0.5 times apart from d1.
And vertical cabling 430 (b) is in order to the horizontal cabling 420 of vertical connection (b) and 420 (c), and disposes abreast apart from d1 between 2 times.Vertical cabling 430 (b) is to equate in fact with the distance of vertical cabling 430 (a).In other words, the distance of vertical cabling 430 (b) adjacent with the left and right sides two vertical cablings 430 (b) is all between 0.5 times apart from d1.
Vertical cabling 430 (c) is in order to the horizontal cabling 420 of vertical connection (c) and 420 (d), and similarly disposes abreast apart from d1 between 2 times.Vertical cabling 430 (c) is staggered with vertical cabling 430 (b), and is to equate in fact with the distance of vertical cabling 430 (b).In other words, the distance of vertical cabling 430 (a) adjacent with the left and right sides two vertical cablings 430 (b) is all spacing d1.
And vertical cabling 430 (d) is in order to the horizontal cabling 420 of vertical connection (d) and 420 (e), and similarly disposes abreast apart from d1 between 2 times.Vertical cabling 430 (d) is staggered with vertical cabling 430 (c), and is to equate in fact with the distance of vertical cabling 430 (c).In other words, the distance of vertical cabling 430 (d) adjacent with the left and right sides two vertical cablings 430 (c) is all spacing d1.
The length of main storage electrode line 252 is to be h5, and main storage electrode line 252 is in order to couple data driver 110 and transmission line 410.The voltage V of data driver 110 outputs
StBe passed to branch's storage electrode line 250 (1) to 250 (9) through main storage electrode line 252 and transmission line 410.
Because the shortest path length between data driver 110 and the branch's storage electrode line 250 (1) to 250 (9) is all (4d1+h1+h2+h3+h4+h5), therefore, branch's storage electrode line 250 (1) to 250 (9) will equate in fact with resistance between the data driver 110, and so that the voltage V that branch's storage electrode line 250 (1) to 250 (9) receives
