bCan further have jagged edge.In addition, make the LCD of the pel array 200 with LCD keep superior display quality, the pel array 200 of the LCD of present embodiment can further comprise one first common lines 142, one second common lines 144, one the 3rd common lines 242, one the 4th common lines 244.In addition, above first common lines 142, one second common lines 144, one the 3rd common lines 242, one the 4th common lines 244, more can further comprise respectively and dispose at least one first top electrode pattern, at least one second top electrode pattern, at least one the 3rd top electrode pattern and at least one the 4th top electrode pattern (not shown among Fig. 2, as to please refer to the setting of top electrode pattern shown in Figure 1 152,154).
Except the set-up mode of the described dot structure group of above-mentioned Fig. 2, the setting of other dot structure group can also be arranged, as shown in Figure 3.In Fig. 3, the pel array 300 of LCD is similar with the pel array 200 of the LCD of Fig. 2, but the two main difference part is: the first switch module 232a of the first dot structure 330a in the dot structure group 330 of present embodiment is electrically connected to different data lines respectively with the second switch assembly 232b of the second dot structure 330b.Further say, the position at the position at the first switch module 232a place and second switch assembly 232b place is in alignment with each other, and the first switch module 232a and second switch assembly 232b lay respectively at the corner regions of the first dot structure 330a and the second dot structure 330b.In addition, in this corner regions, the first switch module 232a and the first data line DL1 electrically connect, and the second switch assembly 232b and the second data line DL2 electrically connect.
As shown in Figure 3, in the second dot structure 330b, the second data line DL2 has an extension DL ' who is parallel to sweep trace.Therefore, second switch assembly 232b can electrically connect with the second data line DL2 by extension DL '.Yet, extension DL ' and the pixel electrode 234S second time
bBetween also capacitance coupling effect can take place.In order to reduce the otherness of the capacitance coupling effect between the first dot structure 330a and the second dot structure 330b, the pel array 300 of LCD is configuration one compensating line CL in the first dot structure 330a further.Wherein, compensating line CL can be electrically insulated with the first switch module 232a, and extends to the second data line DL2 with identical bearing of trend with sweep trace and electrically connect with the second data line DL2 from the first switch module 232a.
From the above, present embodiment not only possesses the advantage of first, second embodiment, and first, second dot structure 330a, 330b in each group dot structure 330 also can reduce the difference of capacitance coupling effect to each other by the configuration of compensating line CL.
In addition, according to another embodiment of the present invention, the design of dot structure group can also be as shown in Figure 4.In Fig. 4, the pel array 400 of LCD is similar with the pel array 300 of the LCD of Fig. 3, but the two main difference part is: the first switch module 232a in the dot structure group 430 and second switch assembly 232b lay respectively at the zone line that the first dot structure 430a and the second dot structure 430b are close to a side of corresponding sweep trace.
As shown in Figure 4, the first data line DL1 and the second data line DL2 have the first extension DL1 ' and the second extension DL2 ' that is parallel to sweep trace respectively.Therefore, the first switch module 232a can utilize the first extension DL1 ' and electrically connect with the first data line DL1, and second switch assembly 232b can utilize the second extension DL2 ' and electrically connect with the second data line DL2.Yet the first extension DL1 ' can the while and the first primary and secondary pixel electrode 234M
a, 234S
aProduce capacitive coupling, and the second extension DL2 ' only can with the pixel electrode 234S second time
bProduce capacitive coupling.In order to reduce the otherness of the capacitance coupling effect between the first dot structure 430a and the second dot structure 430b, the pel array 400 of LCD is configuration one first compensating line CL1 in the first dot structure 430a further, and disposes one second compensating line CL2 in the second dot structure 430b.Wherein, the first compensating line CL1 and the first switch module 232a are electrically insulated, and extend to the second data line DL2 with identical bearing of trend with sweep trace and electrically connect with the second data line DL2 from the first switch module 232a; The second compensating line CL2 and second switch assembly 232b are electrically insulated, and extend to the first data line DL1 with identical bearing of trend with sweep trace and electrically connect with the first data line DL1 from second switch assembly 232b.
According to further embodiment of this invention, the design of dot structure group can also be as shown in Figure 5.In Fig. 5, the pel array 500 of LCD is similar with the pel array 400 of the LCD of Fig. 4, but the two main difference part is: the position at the second switch assembly 232b place of the position at the first switch module 232a place of the first dot structure 530a in the dot structure group 530 and the second dot structure 530b is interlaced with each other.In more detail, the first switch module 232a and the first data line DL1 electrically connect, and second switch assembly 232b and the second data line DL2 electrically connect, and wherein the first switch module 232a corner regions that is positioned at the first dot structure 530a can present arrangement mode interlaced with each other with the corner regions that second switch assembly 232b is positioned at the second dot structure 530b.
In the present embodiment, because the first switch module 232a is adjacent to the first data line DL1 and second switch assembly 232b is adjacent to the second data line DL2, therefore, the capacitive coupling of the first dot structure 530a and the second dot structure 530b does not have too big-difference.Yet the deviser also demand of visual product is provided with compensating line in the first dot structure 530a and the second dot structure 530b, but not as limit.
In other embodiments, when the position at the first switch module 232a place is can be with the position at second switch assembly 232b place interlaced with each other, the first switch module 232a and second switch assembly 232b can be electrically connected to same data line, for example the first data line DL1.Certainly, also optionally compensating line is set in position, to compensate the capacity coupled difference of the first dot structure 530a and the second dot structure 530b.
In sum, in the pel array of LCD of the present invention every group or each dot structure are divided into different voltage regime by main pixel electrode with time pixel electrode, the first capacitive coupling pattern electrode pattern that wherein is positioned at time pixel electrode both sides proximity data line and the second capacitive coupling pattern electrode pattern help the stray capacitance between inferior pixel electrode of balance and proximity data line, and better capacitance balancing effect is arranged.Dot structure of the present invention is applied in the LCD, and then the cross-talk phenomenon of this LCD can be improved.
Though the present invention with preferred embodiment openly as above; but it is not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; when can doing a little change and modification, so protection scope of the present invention is as the criterion when looking the accompanying Claim book person of defining.
