Abstract
The invention relates to a capacitive touch screen. The capacitive touch screen comprises a base plate layer, an induction electrode layer and a protection layer, wherein the induction electrode layer consists of several parallel induction electrode groups arranged in sequence; and the induction electrode layer is located between the base plate layer and the protection layer. The capacitive touch screen with the single-layer induction electrode parallel layout structure is simple in manufacture and has low cost, and is suitable for the wide range application.
Description
Technical field
The present invention relates to a kind of capacitance type touch control screen, especially a kind of capacitance type touch control screen simple in structure, with low cost.
Background technology
Touch screen has been applied on the various multimedia electronic equipments now widely, like mobile phone, and MP3; Panel computer etc.; Along with apple IPHONE, IPAD's is popular, and the touch screen technology also develops into present projected capacitive touch screen by traditional resistance-type; And projected capacitive touch screen induction electrode mainly is made up of ITO (indium tin oxide); ITO is a kind of critical material of 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 wiring that the projected capacitive touch screen is gone up ITO generally is single-surface double-layer or two-sided single layer structure; Its cardinal principle is: utilize people's bulk electric field; When the user touches; 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 same one side of glass substrate; For fear of the conducting between the two-layer different directions electrode,, so just can double-deck ITO be laid on the same one 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 for the user touch screen a kind of simple in structure, with low cost to be provided.
In order to realize above-mentioned purpose of the present invention; The invention provides a kind of capacitance type touch control screen; Comprise substrate layer, induction electrode layer and protective seam; Said induction electrode layer is arranged in order by some parallel induction electrode groups to be formed, and said induction electrode layer is between said substrate layer and protective seam.
The described individual layer induction electrode of a kind of capacitance type touch control screen of the present invention wire structures, double-deck relatively induction electrode wiring, manufacturing process is simpler; So it is with low cost; Moreover the touch-screen thinner thickness of being made up of the individual layer induction electrode is so be worthy of popularization.

Fig. 1 is a kind of embodiment according to a kind of capacitance type touch control screen according to the invention.
Fig. 2 is the synoptic diagram of the inductive layer Butut of a kind of capacitance type touch control screen 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 a kind of capacitance type touch control screen 3, comprise substrate layer 32, induction electrode layer 31 and protective seam 30, said induction electrode layer 31 is between said substrate layer 32 and protective seam 30.
More concrete is, induction electrode layer cloth 31 is put on substrate layer 32, and protective seam 30 is positioned at 3 outermost layers of touch screen, be positioned at inductive layer 31 above.
Please refer to shown in Figure 2; Wire structures for the individual layer induction electrode of capacitance type touch control screen of the present invention; Said induction electrode layer 31 is made up of a plurality of induction electrode groups 10, and said induction electrode group 10 has two induction electrodes 11 and 12, wherein; Said two induction electrodes 11 and 12 1 are anodal, and one is negative pole.Said induction electrode 11 is opposed in opposite directions with said induction electrode 12.Said positive and negative induction electrode 11 and 12 width are alternation trend, are like an induction electrode to increase progressively trend, so another induction electrode trend that then tapers off.Positive induction electrode 11 in the said induction electrode group 10 is connected respectively on the respective pins of touch-control chip 20 through lead with negative induction electrode 12.
Capacitance type touch control screen of the present invention, said substrate layer, induction electrode layer and protective seam are transparent material, in order to improve the transmittance of touch screen; The general transmittance of using is than higher material; General said substrate layer is a silicon dioxide, and the induction electrode layer is ITO, and protective seam is a tempered glass.
Above character introduction and description of drawings; Realize the concrete implementation method of said a kind of capacitance type touch control screen for the present invention; Be core concept and method for a better understanding of the present invention, those skilled in the art will appreciate that all based on above-mentioned technological thought method; That makes quoting or improving, all within protection scope of the present invention.
