Abstract
The invention relates to a single layer indium tin oxide (ITO) wiring structure. The structure consists of a plurality of touch electrode groups which are sequentially arranged, wherein each touch electrode group comprises a positive touch electrode and a negative touch electrode; the positive touch electrode and the negative touch electrode in each group are arranged opposite to each other; and the opposite part of the two electrodes has an S-shaped curve shape. Compared with a double layer ITO wiring structure, the single layer ITO wiring structure has a simpler manufacturing process, so that the cost is low; in addition, a touch screen which consists of single layer ITO is relatively thin, so that detected data is easy to process.
Description
Technical field
The present invention relates to the wire structures of a kind of ITO, refer in particular to the wire structures of a kind of individual layer ITO.
Background technology
So-called ITO (indium tin oxide) is a kind of critical material that is used to produce LCD, and at present, it has all had in fields such as instrument and meter, computing machine, electronic watch, game machine and household electrical appliance very widely uses.The capacitive touch screen of big heat also is to utilize ITO to accomplish the action that detecting touches on the market in recent years; And the wiring of ITO generally is double-deck on the capacitance touch screen; Its cardinal principle is: utilize people's bulk electric field; When the user touched, the mutual capacitance (also claiming coupling capacitance) of the infall sensing unit of surface row or row can change, and finally can detect the particular location of touch point according to above-mentioned variation.
The structure of common double-deck ITO is a diamond structure; Its double-deck ITO is laid in respectively on the ipsilateral of glass substrate; For fear of the mutual conduction between the electrode,, so just can double-deck ITO be laid on the same side of glass substrate so bridge contact need be set on glass substrate.Though said method has been realized the action that detecting touches, the touch screen structure of the double-deck ITO of this employing, not only complex process, and bridge joint place damages easily, and the product yield is low, causes cost to raise.In order to overcome above-mentioned shortcoming, part manufacturer is arranged to rectangle with the structure of ITO, two-sidedly then is arranged on the two-layer of glass substrate; So, really simple much of technology, and improved the product yield; But what still adopt is the wire structures of double-deck ITO; The cost of ITO own is just higher, adds structure of two layers, and the thickness that forms touch-screen has thus also just been increased.If can overcome the limitation that double-deck ITO layouts brings, so no matter be to consider that from the cost or the structure of touch-screen individual layer ITO all has more advantages.
Therefore need solve above problem for users provide the wire structures of a kind of easier ITO.
Summary of the invention
The actual technical matters to be solved of the present invention is how to provide a kind of technology simple, the wire structures of individual layer ITO with low cost.
In order to realize above-mentioned purpose of the present invention; The invention provides the wire structures of a kind of individual layer ITO; Constitute by several tactic successively touch-control electrode groups; Said touch-control electrode group comprises positive touch-control electrode and negative touch-control electrode, and positive touch-control electrode and negative touch-control electrode in said every group are arranged relatively, and the S-shaped curve of the opposite position of two electrodes.
The wire structures of individual layer ITO of the present invention, the wiring of double-deck relatively ITO, manufacturing process is simpler, thus with low cost, moreover, by the touch-screen thinner thickness that individual layer ITO forms, be easy to handle the data of detecting.
Description of drawings
Fig. 1 is first kind of embodiment according to individual layer ITO wiring according to the invention.
Fig. 2 is second kind of embodiment according to individual layer ITO wiring according to the invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Please refer to shown in Figure 1ly, the present invention relates to the wire structures of individual layer ITO, said ITO layer 1 is made up of a plurality of touch-control electrodes 10, and said touch-control electrode 10 has two touch- control electrodes 11 and 12, is staggered successively.Wherein, said two touch- control electrodes 11 and 12 1 are anodal, and one is negative pole, forms a touch-control electrode group, and has just constituted individual layer ITO by several tactic successively touch-control electrode groups.
Said touch-control electrode 11 in the said touch-control electrode group is arranged with said touch-control electrode 12 relatively, and the S-shaped curve of opposite position.In the said touch-control electrode group, the electrode on direction is laid in the void area between another direction electrode respectively.Said positive and negative touch- control electrode 11 and 12 area are alternation trend, if a touch-control electrode is and increases progressively trend, and another touch-control electrode trend that then tapers off so.Positive touch-control electrode 11 in said every group of touch-control electrode is connected respectively on the respective pins of touch-control chip 2 through lead with negative touch-control electrode 12 in every group of touch-control electrode.
Among said Fig. 1 among the individual layer ITO 1 touch-control electrode 10 form by the class triangle, wherein, hypotenuse is a curve, and is S-shaped.Positive and negative touch-control electrode area in said every group of touch-control electrode group equates, and the spacing of said every group of touch-control electrode equates that the spacing of promptly said any two electrode groups equates.So, can guarantee to detect more accurately the particular location of touch object.Said positive touch-control electrode 11 is staggered with negative touch-control electrode 12, and each touch-control electrode finally is wired on the respective pins of touch-control chip 2.
Among said Fig. 2 among the individual layer ITO 1 touch-control electrode 10 form by class is trapezoidal, wherein, trapezoidal hypotenuse is a curve, and is S-shaped.Positive and negative touch-control electrode area in said every group of touch-control electrode group equates, and the spacing of said every group of touch-control electrode equates that the spacing of promptly said any two electrode groups equates.So, function match property is good, and is easy to handle the data of detecting.
The above-mentioned detailed layouts of having discussed the individual layer ITO that the touch-control electrode that formed by two kinds of shapes forms; Be beneficial to the particular location that detects touch object, thus be not limited to above-mentioned two kinds of forms, as long as the S-shaped curve of opposite position of two electrodes; Even other shape equally can be designed to above-mentioned layout structure; Because principle is identical, does not discuss one by one, but all should list among protection scope of the present invention.
