Dot structure

Technical field

The present invention relates to a kind of dot structure, and particularly relevant for a kind of dot structure that improves the vertical cross-talk (vertical cross-talk) of LCD.

Background technology

Generally speaking, the dot structure of LCD comprises scan line, data wire, active member and pixel electrode.In dot structure, it is big to be healed in the area design ground of pixel electrode, can promote the aperture opening ratio (aperture ratio) of LCD.Yet, when pixel electrode and data wire too near the time, (capacitance between pixel and data line Cpd) can become big to the stray capacitance between pixel electrode and the data wire.Thus, in the switch element down periods, the voltage of pixel electrode can receive the influence of the signal that data wire transmits and so-called crosstalk effect (cross-talk) takes place, and then influences the display quality of LCD.

In addition, present large-sized LCD uses the drive form of row counter-rotating mostly.Be expert under the drive form of counter-rotating, to equate to make vertical cross-talk be zero for pixel electrode and the coupling capacitance of the holding wire that is positioned at the pixel electrode both sides (data wire) in theory.Wherein, the number that is positioned at the data wire of pixel electrode both sides all only has one, and every data wire is straight, and every neither intermeshing of data wire.But, in fact,, cause having side-play amount to a certain degree between each rete of dot structure because can there be contraposition skew to a certain degree in the multiple tracks masking process of dot structure.To make that so the distance between the holding wire of pixel electrode and its both sides is different, so that the coupling capacitance between the holding wire of pixel electrode and its both sides and unequal.In other words, in fact still there is the problem of vertical cross-talk, and the display quality of LCD is affected.

Summary of the invention
