Abstract
The invention relates to a single-layered ITO (indium tin oxide) wiring structure, which comprises a plurality of positive and negative touch control electrodes, the positive and the negative touch control electrodes are arranged in a staggering way, and the structural distribution of the touch control electrodes of the middle part of a single layer of ITO and the control electrodes of the edge of the single layer of ITO is uneven. Compared with the double-layered ITO wiring structure, the single-layered ITO wiring structure has the advantages that: the manufacturing process is simpler, so the cost is low; and moreover, a touch screen formed by the single layer of ITO is thinner, and therefore the linearity of the formed touch screen is better.
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; Form the interlaced arrangement of said positive and negative touch-control electrode, the touch-control electrode structure skewness of the touch-control electrode of said individual layer ITO center section and marginal portion by a plurality of positive and negative touch-control 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 the touch-screen thinner thickness by individual layer ITO forms has the better linearity degree for the touch-screen that forms.

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; Said touch-control electrode 10 has two touch- control electrodes 11 and 12; Wherein, said two touch- control electrodes 11 and 12 1 are anodal, and one is negative pole.Said touch-control electrode 11 is arranged with said touch-control electrode 12 in opposite directions, and 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.Said individual layer ITO 1 is divided into three parts; Be upper and lower marginal portion and center section; And the touch-control electrode structure skewness of the touch-control electrode of said individual layer ITO 1 center section and marginal portion, promptly the touch-control electrode of said marginal portion is more sparse than the touch-control electrode structure of center section.Said a plurality of touch- control electrode 11 and 12 is divided into two groups, and first group comprises that 11, the second groups at a plurality of positive touch-control electrodes comprise a plurality of negative touch-control electrodes 12, and above-mentioned two arrays of electrodes is connected respectively on the respective pins of touch-control chip 2 through lead.
The positive touch-control electrode 111 and the negative touch-control electrode 121 of the marginal portion among said Fig. 1 among the individual layer ITO 1 are formed by a triangle, and the positive touch-control electrode 112 of center section is formed by two triangles with negative touch-control electrode 122.Wherein, the positive touch-control electrode 111 of marginal portion equates that with negative touch-control electrode 121 areas the positive touch-control electrode 112 of center section also equates with negative touch-control electrode 122 areas.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.
The positive and negative touch-control electrode 11 of the marginal portion among said Fig. 2 among the individual layer ITO 1 and 12 is formed by two triangles, and the positive touch-control electrode 11 of center section is formed whole individual layer ITO layout structure indentation with negative touch-control electrode 12 by three triangles.Wherein, the positive touch-control electrode 11 of marginal portion equates that with negative touch-control electrode 12 areas the positive touch-control electrode 11 of center section also equates with negative touch-control electrode 12 areas.Said positive touch-control electrode 11 is staggered with said negative touch-control electrode 12; This moment first group touch-control electrode by the positive electrode with ditrigon 111 with have three leg-of-mutton positive electrodes 112 and form, second group touch-control electrode is by the negative electrode with ditrigon 121 and have three leg-of-mutton negative electrodes 122 and form.Because in the layout structure of individual layer ITO 1 of the present invention, the topology layout of center section is tighter, and the topology layout of upper and lower two edges part is loose, thus the problem that solves edge treated of utilizing is arranged, and also matching performance is good each other on the function; Moreover the individual layer ITO of employing said structure because each electrode is formed by several triangles, so the data that draw are more, is easy to handle, and for the touch-screen that forms the better linearity degree is arranged.
Above-mentioned detailed the argumentation mixed the layouts of the triangle of composition for individual layer ITO 1; Be not limited to the form of above-mentioned mixing; And singly be not that the touch-control electrode that triangle forms has above-mentioned layout structure, other shape can be designed to above-mentioned layout structure as trapezoidal, arc, because principle is identical; Do not discuss one by one, but all should list among protection scope of the present invention.
