Abstract
The invention adds a compensation branch electrode on each side of a pixel electrode of an active matrix LCD, thus balancing parasitic capacitances formed by the pixel electrode and data lines on its two sides through parasitic capacitances formed by the compensation branch electrode and the data lines because of process offset; and on the condition of using point or straight-line reverse drive, able to balance parasitic capacitance effect and simultaneously reduce parasitic capacitance imbalance caused by crosstalk or nonuniformity at exposure joint.
Description
Technical field
The present invention relates to a kind of Thin Film Transistor-LCD component structure and technology, particularly relate to can the compensation pixel electrode and signal wire between the design of stray capacitance.
Background technology
Generally speaking, liquid crystal panel causes data line and the overlapping skew of pixel electrode because of process deviation easily, make pixel electrode and data line too approaching, produce stray capacitance (parasiticcapacitance between pixel and data line as shown in Figure 1, Cpd, Cpd '), (cross talk) phenomenon and excessive stray capacitance will cause crosstalking; Or because the difference that the exposure joint produces, also cause overlapping skew easily and produce exposure and engage uneven problems affect image quality such as (shot mura).These all are one of principal elements that influences pixel electrode aperture opening ratio size design.
Therefore, for reducing parasitic capacitance effect and reaching the demand of high aperture, prior art utilizes different designs to solve, for example with covering electric capacity (shielding Cs), and between data line and pixel electrode, add one layer of polymeric insulation film (polymer insulator film).Wherein, add the design of one layer of polymeric insulation film, though can reduce parasitic capacitance effect, and can allow pixel electrode cross over data line and reach high aperture, yet the impact polymer insulation film reduces the parameter of parasitic capacitance effect, depends primarily on the dielectric coefficient of selected polymer insulation film, and the thickness size of polymer insulation film, that is the size of pixel electrode and data line distance.Be subject to the exploitation of polymer insulation membraneous material, influenced by other processing step with its dielectric coefficient value and thickness and change, so still can influence the ability that stray capacitance is reduced.Therefore, the difference in size of pixel electrode and data line lap still can cause the imbalance of Cpd and Cpd ', crosstalks or other defective and produce.
In addition, for solving the effect that stray capacitance caused, the liquid crystal panel that utilizes some counter-rotating (dot inversion) or craspedodrome counter-rotating modes such as (column inversion) to drive is also arranged at present, so that the signal positive-negative polarity that adjacent data line was sent with the time is opposite, and then allow Cpd and Cpd ' offset.And, if the area that allows pixel electrode cross on the right and left data line is simultaneously fixed, more Δ Cpd can be reduced to minimum.
But, though on the topological design of photomask, can the fixed pixel electrode and the overlapping area of data line, as shown in Figure 2, Fig. 2 is the pixel electrode and the overlapping synoptic diagram of data line of primary light mask.In original photomask design, each pixel electrode 20 and left and right sides data line 26,28 overlapping areas equate.Yet on actual production technology, the skew that original design load but may produce different contraposition layers because of gold-tinted technology, and take place as the situation of pixel electrode on the actual panel that Fig. 3 illustrated 30 with the overlapping area variation of left and right sides data line 36,38, the overlapping area that causes pixel electrode 30 and left data line 36 causes the imbalance of stray capacitance greater than the overlapping area of pixel electrode 30 with right side data line 38.
Summary of the invention
The invention provides a kind of can the compensation pixel electrode and signal wire between the structure and the technology of Thin Film Transistor-LCD element of stray capacitance, to solve the effect that existing stray capacitance is caused.
According to claim of the present invention, it respectively increases by a compensation branch electrode in former pixel electrode both sides, because of the stray capacitance that process shifts and data line are produced, makes the stray capacitance balance of the data line of pixel electrode and the right and left with the compensation pixel electrode.Therefore, under the situation of using some inversion driving or craspedodrome inversion driving (the adjacent data line positive-negative polarity is opposite), can balance Cpd and the effect of Cpd ', and lower simultaneously and crosstalk or uneven unbalanced phenomenon of equal Cpd, Cpd ' that is caused of uneven Cpd, Cpd ' that other produces because of the exposure joint.
Because the present invention has the design of compensation pixel electrode, thus can effectively solve because of process deviation makes data line and the overlapping skew of pixel electrode, and generation is crosstalked or because the unequal problem that influences image quality that the exposure joint produces.In addition, the invention is not restricted to the design of linear pattern data line, it also can be applicable to the design of zigzag data line, and arranges the LCD of pixel design with triangular form (delta).
