Abstract
The invention provides a wiring structure of a single-layer ITO (indium tin oxide). The wiring structure is composed of a plurality of positive and negative touch electrodes; and an edge of the touch electrode is provided with a boss. The wiring structure of the single-layer ITO has simpler manufacturing process in comparison with the wiring structure of a dual-layer ITO; therefore, the cost is low; furthermore, a touch screen made of the single-layer ITO is thinner and has good mutual matching performance in function.
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, it is made up of a plurality of positive and negative touch-control electrodes, and an edge of said positive and negative touch-control electrode is provided with a convexity.The wire structures of individual layer ITO of the present invention, the wiring of double-deck relatively ITO, manufacturing process is simpler, so with low cost; Moreover by the touch-screen thinner thickness that individual layer ITO forms, matching performance is good each other on the function.
Description of drawings
Fig. 1 is the structural representation of 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 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 width of said touch-control electrode 11,12 demonstrates the trend of alternation; One of the width of said positive and negative touch-control electrode is when increasing progressively trend; Another trend that then tapers off, therefore an end of wherein said touch-control electrode 11 relative broads is in an end place of another said touch-control electrode 12 relative narrower.On an edge of said touch-control electrode, be provided with convexity 13,14, described protruding 13,14 position is near the narrower end of said touch-control electrode.Identical and the area of two said electrode 11,12 shapes equates, the position of a touch-control electrode 11 another touch-control electrode 12 dextrorotation turnbacks relatively wherein, and promptly two said electrodes become the center symmetry.
Said protruding 13,14 can extend to long end from a narrower end, and limiting case can be said convexity extends to broad always from the narrower end of said touch-control electrode a end.The advantage of this structure is to increase near the said narrower area of an end, thereby increases the sensitivity and the degree of accuracy of touch-control.
Compared with prior art, capacitive touch screen of the present invention is provided with both positive and negative touch-control electrode on one deck ITO, simple in structure, and has reduced the ITO layer, has also reduced the cost of touch-screen.
The present invention is not limited to the foregoing description, and said touch-control electrode 11,12 also can be selected other shapes for use, depends on the position and the size of said convexity, just gives unnecessary details no longer one by one because principle is identical, all should list in protection scope of the present invention.
