PdWith C
Pd' produce.Stray capacitance C
PdWith C
Pd' capacitance depend on the area that transparency conductive electrode 27 and adjacent data distribution 13 overlap.
Though according to the planning of each road mask, each transparency conductive electrode 27 should be with the area that adjacent data distribution 13 overlaps and equates.But on reality was made, using between the lithography process of each road mask all to have so-called overlapping amount skew (overlay shift) to produce.This overlapping amount skew easier generation in the technology of large size panel.When the overlapping amount skew (overlay shift) of the transparency conductive electrode 27 of subregion and adjacent data distribution 13 greatly too the time, under a conversion (dot inversion), can make stray capacitance C in the single dot structure
PdWith C
Pd' capacitance because of differing too much, cause the capacitance coupling effect of opposed polarity to offset each other, so that feasible display panels (not illustrating) with thin-film transistor array base-plate 20 mades can demonstrate striped under same grey menu, or the phenomenon that other shows uneven (mura) occurs.
