Abstract
The invention relates to a wiring structure with single layer indium tin oxide (ITO). The structure consists of a plurality of positive touch electrodes and a plurality of negative touch electrodes, wherein the positive touch electrodes and the negative touch electrodes are arranged oppositely; and the electrodes in one direction are arranged in gap areas among the electrodes in the other direction. Compared with a wiring structure with double layer ITO, the wiring structure with the single layer ITO has the advantages that: the manufacturing process is simpler, so cost is low; and a touch screen consisting of the single layer ITO has high mutual matching performance in function due to a small thickness.
Description
Technical field
The present invention relates to the wire structures of ITO, refer in particular to the wire structures 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; Be made up of a plurality of positive and negative touch-control electrodes, said positive and negative touch-control electrode is arranged in opposite directions, and the electrode on direction is laid in the void area between another direction electrode respectively.
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, matching performance is good each other on the function.

Fig. 3 is the third 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 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.
Positive touch-control electrode 11 in the ITO layer 1 that relates among said Fig. 1 is formed by ditrigon with negative touch-control electrode 12; Indentation; Said positive touch-control electrode 11 is staggered with said negative touch-control electrode 12; And area equates, a plurality of touch-control electrodes 12 interlaced arrangements of a plurality of touch-control electrodes 11 of first group and second group in the promptly said ITO layer 1.Each touch- control electrode 11 and 12 in the said two arrays of electrodes finally is wired on the respective pins of touch-control chip 2.
Positive and negative touch- control electrode 11 and 12 in the ITO layer 1 that relates among said Fig. 2 is indentation also; But form by three triangles; And said positive touch-control electrode 11 still is staggered with said negative touch-control electrode 12; And area equates, a plurality of touch-control electrodes 12 interlaced arrangements of a plurality of touch-control electrodes 11 of first group and second group in the promptly said ITO layer 1.
Positive and negative touch- control electrode 11 and 12 in the ITO layer 1 that relates among said Fig. 3 is indentation also; Wherein, The electrode 111 and 121 that is arranged in the upper and lower part of said ITO layer 1 is made up of ditrigon; The electrode 112 of center section and 122 is made up of three triangles; And 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.A plurality of touch-control electrodes 12 interlaced arrangements of a plurality of touch-control electrodes 11 of first group and second group in the said ITO layer 1, said electrode is connected on the respective pins of touch-control chip 2 through the lead correspondence.Said structure is divided into three parts in upper, middle and lower with individual layer ITO; The layout of center section is tighter, adopts the electrode of being made up of three triangles, and upper and lower two-part layout is loose; The electrode that employing is made up of two triangles; So, utilize the problem that solves edge treated with regard to having, and matching performance is good each other on the function; Moreover the individual layer ITO of employing said structure owing to being three parts in upper, middle and lower with an entire cloth score of the game, so the data that draw are more, is easy to handle, and for the touch-screen that forms the better linearity degree is arranged.
The wire structures of the above-mentioned detailed touch-control electrode of having discussed ditrigon, three triangles and having combined by both to form; Wire structures is similar, so thisly all can be laid on the individual layer ITO, in addition greater than two leg-of-mutton wirings; With similar other shape of the present invention; Such as trapezoidal, arc etc., as long as two electrodes are alternation trend, and interlaced arrangement all should be listed among protection scope of the present invention.
